The Threat Of Nuclear Weapons Essay Research free essay sample

The Threat Of Nuclear Weapons Essay, Research Paper Ever since the first atomic arm was built in 1945, atomic war has been a menace. The two major atomic powers in the universe today are the Soviet Union and the United States. If a war of all time broke out between the two, which involved the usage of atomic arms, the whole universe would endure from the effects. In this study I am traveling to turn out that atomic arms are a menace to all of us. A atomic arm is any device that causes an detonation by the release of the energy in an atom. They are much more powerful than any conventional or # 8220 ; non atomic # 8221 ; arms. Nuclear arms are divided into two groups: fission arms, which are frequently called atom bombs, and thermonuclear or merger arms, which are frequently called H bombs because that is what they are made of. FISSION WEAPONS Fission arms cause an detonation by the splitting of atomic karyon. We will write a custom essay sample on The Threat Of Nuclear Weapons Essay Research or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page This happens when a neutron collides with the karyon of an atom. The protons in the karyon are transformed into a great sum of energy and two or three more neutrons are sent out, which go on to divide other karyon. If this continues a procedure called a concatenation reaction will happen. When this happens a fission detonation is the consequence. To organize a concatenation reaction, a certain sum of stuff is needed. This sum is known as the critical mass. If the sum is excessively little it is known as a subcritical mass. The critical mass of a material depends on its pureness. The stuffs used in doing fission arms are uranium and Pu. They are the lone elements able to be used in doing a fission arm. There are two different ways to do a fission arm: the gun-type method and the implosion method. In the gun-type method, two pieces of stuff, each holding a subcritical mass, are placed at opposite terminals of a metal cylinder. One of the pieces has a powerful, nonnuclear explosive behind it that explodes on impact and drives the piece into the 1 at the other terminal. The atoms in the stuff the collide and get down a concatenation reaction. In the implosion method a ball of either uranium or Pu is surrounded by a big sum of nonnuclear explosive. When triggered it compresses the atomic stuff, which besides causes a concatenation reaction. FUSION WEAPONS Thermonuclear or merger arms get their destructive power from the combine of light atoms. Hydrogen, the lightest component, is used in doing merger arms. When the atoms of the component fuse, they release a great sum of energy. The lone job is that the vitamin E lement must be heated to a temperature of 50 million grades Celsius. The lone manner to make this, without utilizing more energy than is produced, is to utilize a fission detonation. So, a ball of H is surrounded by either U or Pu and so by a non atomic explosive. When the explosive is set off it causes the U or Pu to fission, which in bend causes the H to blend. History In 1939, the U.S. authorities became concerned that the Nazi Germans may be capable of constructing a atomic arm, so upon fall ining World War II, the United Sates began a secret operation called the Manhattan Undertaking to construct their ain atomic arm. The first experimental atomic arm was exploded on July 16,1945, by J. Robert Oppenheimer. It was a 22 kiloton implosion-type device. This trial convinced the U.S. authorities that atomic arms could be used in war. On August 6, 1945, the United States used the first atomic arm on the Nipponese metropolis of Hiroshima. It was a 13 kiloton gun-type fission bomb. Three yearss subsequently, the United States dropped a 22 kiloton implosion-type fission bomb on another Nipponese metropolis called Nagasaki. On August 14, eight yearss after the first bomb was dropped, the Nipponese surrendered, which brought an terminal to World War II. Effects The three chief effects that would follow a atomic detonation are blast, thermic radiation or heat, and radiation. The really first thing to go on is the formation of a bolide. The fireball gives off the thermal radiation that vaporizes anything within a one-fourth stat mi and ignites flammable stuffs within 10 stat mis. The thermic radiation can do oculus hurts every bit good as tegument Burnss called flash Burnss. Between 20 and 30 per cent of the deceases at Hiroshima and Nagasaki were caused by flash Burnss. When the bolide begins to disperse it signifiers a blast moving ridge that travels off from the detonation at velocities up to 400 stat mis per hr. This destroys most edifice within 6 stat mis. It besides kills most people within 3 stat mis and badly injures or kills most people up to 6 stat mis off. Then comes the radiation. It is made up of neutrons that were left over after the detonation. When these neutrons come in contact with populating cells they damage or even destruct them. A individual exposed to big sums of radiation will normally decease. Some scientists believe that the dust and fume from the fires after a atomic war would do a worldwide chilling of the planet, which is known as a atomic winter. For this ground, the states at war would non be the lone 1s to endure.

Georgian Speekle - A Giant Isopod

Georgian Speekle - A Giant Isopod The Georgian speekle is the name given to a giant isopod that was found in the state of Georgia in the United States. Photos of the monstrous-looking creature went viral on the internet, leading to comments like Fake! and Photoshop. However, the animal really does exist and yes, it really is over a foot long. Is an Isopod a Bug? No, the Georgian speekle is not an insect or a bug. One defining characteristic of an insect is that it has six legs. The speekle has many more than six appendages. A bug, on the other hand, belongs to the order Hemiptera and mostly resembles an insect, except it has hardened wings and sucking and piercing mouthparts. The speekle is a type of isopod. Isopods dont have wings, nor do they bite like bugs. While insects, bugs, and isopods are all types of arthropods, they are in separate groups. An isopod is  a type of crustacean, related to crabs and lobsters. Its closest land relatives are pill bugs or the common woodlouse. Of the 20 or so species of isopods, the largest is the giant isopod Bathynomus giganteus. How Big Is the Giant Isopod? While B. giganteus is an example of marine gigantism, its not particularly huge. Its not on the order of, say, a giant squid. A typical isopod is around 5 centimeters long (about 2 inches). An adult B. giganteus can be 17 to 50 centimeters (6.7 to 19.7 inches) long. While thats large enough to look scary, the isopod doesnt pose a threat to people or pets. Giant Isopod Facts B. giganteus lives in deep water, off the coast of Georgia (USA) to Brazil in the Atlantic, including the Caribbean and the Gulf of Mexico. Three other species of giant isopods are found in the Indo-Pacific, but none have been found in the East Pacific or East Atlantic. Because its habitat is largely unexplored, additional species may await discovery. Like other types of arthropods, isopods molt their chitin exoskeletons as they grow. They reproduce by laying eggs. Like other crustaceans, they have blue blood, which is really their circulatory fluid. The hemolymph is blue because it contains the copper-based pigment hemocyanin. Most photographs of isopods show them as gray or brown, but sometimes a sick animal appears blue. Although they look intimidating, isopods arent aggressive predators. Rather, they are opportunistic scavengers, mostly living on decaying organisms in the seas benthic zone. They have been observed eating carrion, as well as small fish and sponges. They use their four sets of jars to tear apart their food. Isopods have compound eyes that have over 4000 facets. Like cat eyes, isopod eyes feature a reflective layer at the back that reflects back light (the tapetum). This enhances their vision under dim conditions and also makes the eyes reflective if a light is shined on them. However, its dark in the depths, so isopods probably dont rely much on sight. Like shrimp, they use their antennae to explore their environment. The antennae house chemoreceptors which can be used to smell and taste molecules around them. Female isopods have a pouch called a marsupium that holds eggs until they are ready to hatch. Males have appendages called peenies and masculinae used transfer sperm to the female after she molts (when her shell is soft). Isopods have the largest eggs of any marine invertebrate, measuring about a centimeter or half an inch in length. Females bury themselves in sediment when they are brooding and stop eating. The eggs hatch into animals that look like their parents, except smaller and missing the last pair of legs. They gain the final appendages after they grow and molt. In addition to crawling along in the sediment, isopods are skillful swimmers. They can swim either right-side up or upside-down. Isopods in Captivity A few giant isopods have been kept in captivity. One specimen became famous because it wouldnt eat. This isopod appeared healthy, yet refused food for five years. It eventually died, but its unclear whether starvation is what killed it. Because isopods live on the sea floor, they can go a very long time before encountering a meal. Giant isopods at the Aquarium of the Pacific are fed dead mackerel. These isopods tend to eat four to ten times a year. When they eat, they gorge themselves to the point where they have trouble moving. Although the animals arent aggressive, they do bite. Handlers wear gloves when working with them. Like pillbugs, giant isopods curl up into a ball when threatened. This helps protective their vulnerable internal organs from attack. References Lowry, J.

The Importance of Space Essay Example | Topics and Well Written Essays - 2000 words

The Importance of Space - Essay Example This paper illustrates that during construction one must be able to understand elements such as space, centers, boundaries, paths and alignments during construction. According to David Summers conceptualization, the center was used to define a place where heavens could be traced.According to this author, the center was not articulated initially but stones were placed as signs of signifying the rising of the sun and moon1. The author also argues that paths are important since they acknowledge places and centers hence providing a means of approach and departure. He further argues that the paths cannot be in place without the concept of understanding lines. According to the author, most of the lines converge at the center. On the other hand, the purpose of alignment is to put the center in the most direct possible contact with the external thing that may be the moon, mountain or another center. Using David Summer’s conceptualization the building was located in the center. Surroun ding the mansion was a brick wall in a rectangular manner. The building was located at the center to allow for approach and departure from both sides. From the gate directly to the main entrance of the building is a path neatly done with stone blocks. The main entry faces the gate. This is aimed at ensuring that visitors do not interfere with private properties. The direct path from the gate is also important in case of emergency and this can help in the evacuation. From the main door inside the building is a path that leads to the sitting room and to the diner. On the left is the visitor's bedroom. There is a considerable space between the dining room and the sitting room allowing space for easy movement. The main window is located just near the main entrance door which also illuminates light into the house. The path from the main entrance leads directly to an exit which can also be used as an emergency door in case of any danger. The rear end of the building also contains a wider spacing which is open. However, this spacing is private in the sense that only recommended people can access it especially those living and working within the building.

Comparative Education Essay Example for Free

Comparative Education Essay France has a highly organized educational system, which is divided into primary, secondary and tertiary (college) education. Primary and secondary education is usually imparted at public schools although a strong network of private schools also exists. All educational programs in France are regulated by the Ministry of National Education. Schooling in France is mandatory as of age 6, the first year of primary school while secondary education consists of college for the first four years after primary school and the lycee for the next three years. The baccalaureat is the end-of-lycee diploma that students must attain and is comparable to British A-Levels and American SATs. Students have a choice of sitting for the baccalaureat general which is divided into 3 streams of study, the baccalaureat technologique or baccalaureat professionnel. Higher education is funded by the state and fees are very low. Students from low-income families can also apply for scholarships. Academic councils called academies are responsible for supervising all aspects of University education in a given region. ANALYSING TECHNOLOGY EDUCATION THROUGH THE CURRICULAR EVOLUTION AND THE INVESTIGATION THEMES France Twenty years ago, many of them started with this new concept: introducing technology education (TE) in our curriculum. From this point, we developed many project implementing this new subject area and we built progressively meaningful to this area. The aim of this paper is to present this evolution from the French viewpoint with some interest to compare with foreign experiences. We present this evolution through two perspectives: the curricular evolution and the place ofinvestigation. Briefly, we can observe through the French national curriculum a phase of Epistemological delimitation, followed by a phase of activities definitions, arriving, recently, to a phase of activities defined as applied sciences without poor link to the initial epistemological definition. Over these factual dimensions, we can analyze this evolution as the weakness of the knowledge meaningful expressed in the national curriculum, weakness that reinforce the weakness of the TE in front of other subjects as math, literature, foreign language†¦ Many works tried to analyse this particular approach but their audience never really get out the little sphere of TE investigators. A birthday is more the occasion to open perspective and project some ideas and the experience taught us that the position of TE is more a question of social positioning through the knowledge than a question of purposed activities’ interest. 1. CURRICULUM EVOLUTION IN FRANCE The aim of this paper is to present you some aspects about Technology Education in the French school. French schooling has two levels. Primary school starts at the age of three and lasts until the age of eleven, in three cycles: the initial learning cycle (children three to five years old), the basic learning cycle (five to eight years), and the fundamental learning cycle (eight to eleven). Secondary school is divided into two main cycles: middle school (ages eleven to fifteen) and high school (fifteen to eighteen for general education or fifteen to nineteen for vocational training). Technology education was implemented at each of these two levels in the early eighties. 1. 1 THE FIRST CURRICULUM 1. 1. 1 Some elements about the general background The main idea of French schooling is the progressive elaboration of the different school subjects. Understanding the world of children goes hand in hand with organizing that world in different knowledge areas, from the general view to the particular description given by the different subjects. Technology education, like that of science, history, or geography, appears as a school subject specific to the middle school level (Ginestie, 2001a). The second idea of French schooling is the concept of project pedagogy. The introduction of this pedagogy in the Eighties was a departure from a traditional idea that the academic and dogmatic transmission of knowledge is the sole approach to teaching. Under the pressure of a massive rise in number pupils in middle and high schools, project pedagogy was presented as a possible solution to meeting the needs of the diversity of pupils, addressing their individual needs, and developing pupil autonomy (Ginestie, 2002). It was in this context, in 1985, that technology education was introduced in France as a part of science and technology education in elementary schools, as a new subject for all pupils in middle schools and as an optional subject in high schools. We can note four stages of organization of technology education between 1985 and today. 1. 1. 2 1985-1991: the implementation of the first curriculum Technology education was conceived of as a new subject and took the place of MTE (manual and technical education) in terms of hours, classrooms, and teachers. The curriculum emphasized the industrial environment, leaving little room for home economics and craftsmanship (COPRET, 1984). It had two different elements that made these references plain. On the one hand, the general part of the course described the overall goals, context, and aims of technology education in France. The aims were in terms of pupils attitudes towards technology (as related in many papers, e. g. de Vries, 1994; Jones, 1997; Compton Jones, 1998; Gardner Hill, 1999; Dugger, 2000) and in terms of the social and professional world of industrial production (this idea can also be found in many papers all over the world, e. g. Kantola et al. , 1999). It offered a broad perspective to prepare pupils for professional training. At that time, the middle school became the intermediate cycle where pupils had to make their own personal plan for school, and technology education was responsible for indicating possible career choices. On the other hand, general goals were broken down into concepts and skills. This second element of the curriculum described the organization of concepts based on four domains of reference: mechanical construction, electrical construction, and economics management and computer science. Clearly, the chosen references oriented technology education in Jacques Ginestie Analyzing Technology Education the world of industry towards electro-mechanical production, to the exclusion of other possibilities (Ginestie, 2001b). The main problem in introducing the TE curriculum has been to link the general aims to the specific fields (Sanders, 1999; Ginestie, 2004). These difficulties appeared with in-service teacher training programs. Earlier, the French Ministry of Education strongly affirmed the principle that TE was not a compendium of a little mechanics, a little electronics, and a business management with different aspects of computer science as a binder. To link these subjects together, teachers have had to connect general aims and specific concepts into an overall pedagogical project (Ginestie, 2005). Many in-service teacher training programs develop this orientation rather than aiming simply for the acquisition of specific knowledge. The implementation of technology education has not been reduced to the simple substitution of cooking or handicraft lessons by lessons in mechanics, but the true construction of a new world (Ginestie, 2003). Many original curriculum experiments were conducted at the same time to develop new teaching approaches (differential pedagogy, autonomous work, cooperative work, personal projects, etc. ) and to integrate the new references to industry, the market economy, and new labor organizations by taking into account the needs, design, production, marketing, use, and rationale of industrial methods. The major plan was to combine the pedagogical project with a theoretical industrial project method (IPM). We can note comparable initiatives in the UK at the same time (e. g. Hennessy Murphy 1999). 1. 2 THE CURRICULUM EVOLUTIONS 1. 2. 1 1992-1999: Introduction of the Industrial Project Method (IPM) At the beginning of the Nineties, IPM appeared to be a good solution for implementing TE in the middle schools. Certainly, IPM has taken an overwhelming place in TE leaving no other alternatives for organizing technology education courses. This position was made official with different additions and modifications to the initial curriculum. The main decision to use IPM was published in 1992 by the French Ministry of Education. This method allows for the simultaneous definition of content and method for organizing the teaching learning process in TE. Everything was done so that each TE teacher plans and organizes a new project each year for each group of pupils. 1. 2. 2 1999-2004: The second curriculum Three problems arose that reduced the role of the project in TE. First, projects were mainly single production projects without any real progression from one year to the next. Secondly, the teachers profile evolved considerably during this period, with a large increase in new graduates from the advanced technological universities. Thirdly, the union of industrial science and technique, with teachers exerting pressure to open the curriculum to new technologies and new patterns of labor organization. The implementation of the new curriculum took four years, from 1996 until 1999. These changes tried to organize the relationship between the respective roles of the project and the concepts. For the first three years of middle school, pupils have to make different modules of the whole project, but they do not have to make all of it. The teachers task is to focus the attention of the pupils on specific points. During the last year, the pupils have to do a complete project (Ginestie, 2001c). The IPM is always a very strong frame of reference for TE in middle school (Ginestie, 2002). 1. 2. 3 2005: And so long, another change. There is actually a new phase of curriculum change. The Ministry of Education wants to promote the pupils individual choices about their future and by consequences the study they have to do. We can observe a real reduction of the TE as general and Jacques Ginestie Analyzing Technology Education Page 3 cultural subject. The general aspects are more and more developed as applications of sciences; the general method is not the process of design and technology but more and more the process of observation and experimentation (as we can find it in sciences education). The main knowledge properly identified as technological knowledge is banished and the first draft of this new curriculum promote the links with the scientific knowledge. The IPM is still a reference but it is more an object to study more than a method to use with pupils. 2. CONDITIONS OF STUDY IN TECHNOLOGY EDUCATION As we can see briefly, the TE curriculum is unstable as we can note through these major changes since the first writing. These changes are not linked with the technological evolution but mainly due to the lack of understanding about the place of TE in the general systems and to the misunderstanding about the aims of this subject and the knowledge taught. This lack of knowledge’s definition is patent when we observe the structure of the curriculum. This question of knowledge is not so easy to solve. Entry through analysing the conditions of study about TE’s knowledge supposes, in terms of questions for research, a strong agreement with two points: o There is some thing to study in technology education; o There would be multiple study conditions, perhaps different. These two points don’t make evidence. A majority of opinion is that TE is simply a kind of mix between handicraft activities and elements to highlight vocational training choices (Ginestie, 2000; Chatoney, 2003; Brandt-Pomares, 2003). In this posture, all the knowledge comes from sciences and TE is only a question of activities or applications. Evidently, this kind of entry weakens the position of TE as school subject and the recent French evolutions must be understood like this. It is the radical opposite we choose to work in our laboratory. First orientation we choose is to understand the significance of the anthropological approach. 2. 1 THE ANTHROPOLOGICAL APPROACH The anthropological approach allows registering knowledge in a theory of the activity and in a social field identified. The articulation between task and activity is incomplete if we do not speak about the manner to make. The manner to make relieves of the technique employed by the person to realise the task, that it is appointed by the situation or by him. The articulation between the task and the technique defines a know-how that expresses the manner to realise a determined task type (Ginestie, 1995). To get off this private organization either to account for the activity, or to clarify the manner to make, supposes the utilisation of language mediation. To tell the manner to make necessitate proceeding to an extraction of the individual praxis to elaborate a praxeological organisation, significant of the manner to realise the type of tasks and the context in which these tasks are registered. In fact, it concerns to give the senses in the typical articulation between tasks and techniques by elaborating a field of meaning in connection with a technology, perhaps with a theory. It is this elaboration of meanings on the practice that defines, in the anthropological perspective, knowledge. This approach allows rendering account organisations of knowledge as relationships between praxis, taken in the senses of the activity oriented to finality, and a field of significations that allows referring practice to a technology and/or to a theory (Ginestie, 2001c). The epistemological entry is interested in the nature of knowledge (well obviously in the evoked anthropological perspective above) and to the demarcation of a field of reference (Ginestie, 1997). Some articulations allow thinking these fields, objects to know that are fastened there and the manner of which they are or been able being, taken into account in the framework of a technology education: i. The world of technical objects, their mode of existence and social organizations by and in order that these objects exist so as to register the technological education in the human and social activity field; ii. The articulations between functioning, function, structure, form in the senses of a lighting of interdependences and the different manners to describe an object; iii. The articulation design, production, utilisation notably for marks given on process put at stake in each of terms, but equally, of a more global manner, either in a specific approach on an object, or from an evolutionist viewpoint, in a perspective of an history of technical activities; iv. The articulation object, activity, language in an ergonomic inscription (from the thing to the object, the object to the tool, the tool to the instrument) as revealers of the bonds between gestures and techniques, techniques and technologies. The report to techniques is thought in this framework as a demarcation; the report to languages notices the elaboration of symbols (in a relationship meaning, meant) but equally tools to think the world of technical objects and to act in this world. Well obviously, this qualification of fields is a bit coarse, it needs to be specified, notably if we want to be able to read existent curricular organisations, perhaps to propose evolution of these organizations. The curricular approach is one way to understand the knowledge’s organizations for teaching purposes. The problem is not the transposition of praxis but the transposition of praxeological organizations. It is not difficult to ask to pupils making something, but it is difficult allowing them to construct the meaningful on what they make. Certainly, the important instability of our curriculum is based on this difficulty to elaborate this meaningful. Furthermore, the curricular entry is envisaged here as one of the stages of the didactic transposition process: that the placement in text of teaching objects in an prescriptive aimed that has to organize the teaching activity, to the breadth of the production of these teaching objects in the framework of the class to elaborate some objects of study for pupils, objects of study that are going to determine activities of pupils. This placement in text defines the matter to teach and induces the manner to teach it. 2. 2 SCHOOL INSTITUTIONALIZATION We can thus notice the specification and identification work that operates in this process of scholastic institutionalisation. School institution is characterized as the placement of interactions, surely tensions, between three poles: the pupil, the professor and the knowledge. As soon as we wish to describe these interactions, we are confronted with a problem of methodology, methodology that derives of course the framework in which place our study. Thus, analysing the conditions of the study is going to concern us in what the school institution puts to the study and the manner that’s this study functions. This crossing of analysis rests on the articulation between task and activity: o The task is significant to the knowledge put at stake in the elaborated situation by the teacher in the framework that is fixed (curricular organizations, conditions of exercises, particular constraints, etc. ); o The activity is significant to the work undertaken by the pupil to progress in the task that is appointed it by the teacher and representative of the knowledge’s learning process. Jacques Ginestie Analyzing Technology Education Page 5 It concerns to define a framework of analysis that allows looking the functioning of a teaching situation (Ginestie, 1992). The initial framework, elaborated by these analyses method, does not prejudge of: o Knowledge put at stake, their presence or not and their school form; o Organizations elaborated by the teacher so as to organize conditions of the study of these knowledge; o Activities developed by the pupil that are induced by the organization put in game for this study. These two cross analyses, task and activity, characterize the interactions between three complementary existing logics but that can also appear as rival: the logic of subject, the logic of teaching and the logic of learning. The first one follows from knowledge organisation and requires an epistemological study; the second one takes in account the professional activity of the teacher considering his organisation, his style, his manner to do, the professional gestures he develops; the last one can be highlight by the learning theories, specifically the viewpoint of socio-constructivism theories. Many works have shown the incidence of these logics on the school situations and how they are inscribed in different references and different temporality. In fact, stressing these three logics in a school institution can be looked of different manners. But, for ourselves, we are really interested by what it happens in a class; specifically, we try to analyze the effects produced by this placement in tension (Ginestie, 1996). On the one hand, this approach allows the identification of the organisational and structural elements that act and interact in the process of teaching-learning. In this perspective, the task appears as the preferential expression of the teaching’s logic. It express simultaneously what is at stake, the context in which it is situated, what it is waited and what it is necessary that the pupil makes to achieve the task. In this senses, the task is a concentrated expression of a totality of values, models, elements of theories, knowledge that base the subject’s references and that identify the teacher in a teaching population. The analysis of the task is therefore significant how curriculum is implemented, in the particular intimacy of a specific class. It is equally significant activities that it induced at pupils. It is also characteristic of the epistemological, curricular, didactical or pedagogical presupposition (Ginestie, Brandt-Pomares, 1998). On the other hand, the passage to the real supposes to put in stake an analysis of the activity of the pupil. His perusal of the task, the manner he has to organize its activity and to orient its actions, what it takes in consideration and what it does not see even, allow characterising his learning process. In this perspective, we can notice difficulties that he meets, the manner whose he processes them, adopted strategies and the planning of his different actions (Ginestie, Andreucci, 1999). Reading activity through the description of the task allows proceeding pupil’s activity with some precise characteristic elements of the task. We can value difficulties met by the pupil and identify which are relevant to the context (the formulation of the task, the organization of conditions of the study, the use of models, materials, etc.) and which notices obstacles to the learning (Amigues, Ginestie, 1991). 3. SCHOOL ORGANISATION AND PUPIL’S WORK Organizations implemented at school, in the classroom and by the teacher have a direct influence on the work of the pupil and on the result of this work. Concerning the technology education (but it is not specific for these subject), it is important to specify and to define what is waited from the pupil, recourses he disposes to get there, the manner whose he gets there. Therefore, we have to understand the evaluation the Jacques Ginestie Analyzing Technology Education Page 6 nature of the goal, the manner to get there but also the breach of the goal; everything that allows to bring in front understanding about the process of knowledge’s transmission-appropriation. From this point, we are not in a curricular approach that has for object to define contents of teaching and to determine goals to reach; we discuss goals fixed by the institution, their institutional pertinence, their coherence in a scholastic organization datum. Of course, the temptation is great to believe that we could have act on prescription as to reduce these gaps. The evolution of curriculum shows that this kind of actions is limited because it enters in social negotiations that the research can illuminate to defect to inspire them, even to affect them. 3. 1 TASK ANALYSE Our entry by the situations is an analytic viewpoint to render real situations of classify or in a prospective perspective to think possible evolution. For that, the crossed analysis task-activity presents a good framework. The task’s analyze gives some understanding about the placement in text (or the placement in word) of the object of study. This placement in text constitutes one of the last stages of the didactical transposition, stage in the course of which the teacher anticipates and executes the production of the object of study that it makes return in its class. Many indicators allow characterising some ingredients of the organisation that it counts to put in place: o The nature of knowledge that he exhibits,  o The display of the result expected at the end of the sequence, o The spatial and temporal organization type that he puts in act, o The strategies that he gives to orchestrate the activity of pupils, o The different levels of evaluation on which he counts to lean (evaluation his activity, the progress of his sequence, the activity of pupils, the breach of results), o The devices of mediation and remediation that he envisages, o etc. Others indicators allow to notice explicit or implicit models that he uses for the organization of this production: o model of the logic of pupil learning organized around acquisition of competence noticed to the breadth of significant observable behaviours versus a constructivist approach based on the elaboration of knowledge; o Model of the activity of pupils according to a logic of smooth away difficulties versus a logic of confrontation to obstacles; o Model of the teaching organisation according to a logic of guidance of the action of the pupil versus a logic of problem-solving; o Model of the organization of knowledge references that one can caricature in a binary alternative: in technology education, there is nothing to know versus there is only knowledge. The construction of these models supposes the elaboration of a strong theoretical reference by which we can predict the appearance of the objects of study and how they become into school organisations. Of course, we front three different viability risks: one is an instant risk about what’s happen with the course that is going to unfold here, at this hour, in this  classroom, with this teacher and these pupils; second is a progression risk about what happen in the duration of the class, the articulation of the different sessions and their succession; third is durability risk about the permanency of a teaching at such level, in such class, in such context, according to evolution, development, interaction with the other subjects as a kind of general educational ecology. Jacques Ginestie Analyzing Technology Education Page 7 . 3. 2 ACTIVITY ANALYSE The analyse of the activity, as for it, tries to understand the logic of pupils in their evolution to achieve the task that is confided them and the manner of which they adapt conditions organised by the teacher. Retained indicators refer directly to theories of the apprenticeship, notably through: o The strategy they adopt, o The manner to organize their actions, o The manner to notice and to anticipate difficulties and to overcome them or to avoid them,  o The manner to notice or not constraints imposed by the situation and to take into account them or no, o etc. Analysing the activity of pupils is a powerful tool that allows to notice, to qualify and to valorise gaps between what the teacher waits them, what they obtain really and the manner that they use to reach this result. It concerns, on the one hand, to give indicators of efficiency of a device concerning learning and, on the other hand, indicators on the manner to conceive plan. To adopt a criterion of efficiency of plan put in place by teachers is not easy. That supposes to place the question of the acquisition of knowledge by pupils to the heart of the educational act, what is not without consequences in TE. This challenge is important if we want to reinforce the position and the role of the TE as a general education subject. Through our French experience, but also through some related experiences in different countries, we have change of period. The first time of innovation and implementation is definitively done. Many countries know a decrease period with disaffection for TE: decrease of budget, reduction of school time devoted to the subject. At the same time, more and more teams develop investigation in TE. May be, we have to diffuse the results of these investigations and to develop the support that we can provide to the teacher but also to the curriculum designers, this is our challenge to bring our contribution to TE. ICT and Education in Indonesia Harina Yuhetty I. Introduction  In the beginning globalization is fully believed to be able to lead to greater economic development in the sense of greater market scale, which in turn will increase the gross national product. So people believed that poor countries or third world countries will develop faster, thus the economic gap between the rich developed countries and the third world countries will diminished. However, facts show the contrary. It is true that the gross national product of countries will increase, but the gap between the income of the rich and poor countries is also getting wider. The main reason for this gap is the extra-ordinary growth of information as a result of the development of communications and information technologies in northern developed countries which have full control of these technologies. This information boom enables multinational companies to compete with changes in market demands, new products and new technologies, which in turn can boost the economy of a country, increase its efficiency and win global dominance. On the other hand, in third world countries which are also known as southern hemisphere countries, they have difficulties to seek, to receive, to process and to produce information. The lack of appropriate information at the right time will result in low productivity, low quality research works, and waste of time to pursue information and even to do research which actually had been done by others or in other countries. Indonesia as a third world country has a great concern over this deficiency and believe that the digital divide should be reduced so that there will be an economic recovery. The Indonesian government is determined to utilize the information technology effectively to support efforts to increase the national competitiveness. This aspiration is reflected in the Indonesian Presidential Decree Number 50 year 2000 about the establishment of the Coordination Team of Telemathics of Indonesia. This team consists of all the ministers in the cabinet including the Minister of Education. Its tasks are among others to define the government policy in the area of telemathics; to decide the phases and priorities of development in the area of telemathics and its uses in Indonesia; to monitor and control the implementation of telemathics in Indonesia; and to report the development of telemathics in Indonesia to the President. The government realizes that the success of the development and utilization of telemathics depends mostly on the infrastructure which can provide easy access, and also ensure availability of information and subjects. To meet these three provisions, a competent human resources is a necessity. That is why the preparation of qualified human resources is given priority, because it requires hard work and takes time. Meanwhile, we also know that scarcity of and low quality human resources in the area of Information and Communications Technologies can delay mastery of communication and information technology. As such, the government through the Minister of Efficiency of State Apparatus as Head of the Coordination Team of Telemathics of Indonesia in his letter number 133/M. PAN/5/2001 had drawn up a Five-Year Action Plan for the Development and Implementation of Information and Communication Technologies (ICT) in Indonesia. This plan among others includes a plan for the implementation of the use of telemathics in the area of education starting from 2001 until 2005, which includes: * Develop collaboration between ICT industry and ICT educational institutions through training and R D collaboration, and found a network for skill and capacity development * Develop and implement Curricula of ICT. * Use ICTs as an essential part of the curricula and learning tools in schools/universities and training centers * Establish distance education programs including participation in Global Development Learning and other networks * Facilitate the use of internet for more efficient teaching and learning From this action plan we can see that the emphasis of human resources quality improvement is especially geared on the provision and expansion of education of human resources in ICT area. Besides that, utilization of ICT for education and learning purposes, as an effort to fill digital divide, which in turn is hoped to be able to improve the national competitiveness to revive the economy is another emphase. II. ICT in Indonesia As mentioned above, the success of utilization of ICT is among others depends on the infrastructure which includes the telecommunication network, the availability of internet facilities and the use of internet. In general the development of ICT in Indonesia nowadays is less encouraging compared to the developed countries, or even compared to neighboring countries such as Singapore, Malaysia, Thailand and others. To give a general picture of the ICT condition in Indonesia let us consider the data quoted from the Center for Research and Application of Information and Electronic Technologies of the Office for the Research and Application of Technologies, 2001 as follows. A. Public Telephone Lines for 203,456,005 populace 1. The number of Telephone kiosks 228,862 2. The number of Telephone booths 345,307 3. Telephone patrons 6,304,798 B. Internet 1. Internet Service Providers 40 2. General Access Speed rate of ISPs 15 KBPS 3. Patrons of ISPs 511,000 with 1,980,000 users ( 1% of Indonesian population).

Panopticon: The Ideal Social Order :: essays research papers

Panopticon: The Ideal Social Order "The Panopticon is a marvelous machine which, whatever use one may wish to put it to, produces homogenous effects of power." Panopticism is a style of controlling the individual and making him conform to the system. That system could refer to the police or the world as a whole. There is never a definite top position, therefore, everyone feels as if they are being monitored by someone else. It is for this reason that this disciplinary mechanism is so effective. The Panopticon serves as a tool for discipline and a laboratory of power. The capabilities of a Panopticon are endless. It is the basis for the government while it could also aid in the criminal activities for the mafia. In the government there is a system of checks and balances where nothing can get accomplished without the authorization of a higher ranked official. Once these ideas are passed they are then imposed on the individuals of society by other organizations . Whether it be the police, the IRA, or a neighborhood watch group. The Panopticon can serve the public in many ways. It can defend a country, reform prisoners, treat the ill, and educate the public. It does this by creating channels of power and distributing them to the individuals. In the Panopticon, no one individual shall be granted too much power so as to place his or her own values upon the masses. The concept behind panopticism is the distribution of power in order to better society as a whole. The historical problems with power have proven, when it is unevenly distributed, those with the power take advantage and impose their values on the public. For instance, Hitler was given too much power and he massacred millions of innocent people. The Panopticon, on the other hand, serves to increase the wealth, welfare, education, and spirituality of society. The Panopticon does punish but it does so in a means of reform. It attempts to restore the individual to a being that can be a productive and positive influence. The system has two main purposes, the distribution of power and the means of establishing discipline. Every aspect of the world has the ideas and principles of panopticism behind them. The world is full of intricate and complicated people. These people group together to create tribes, governments, countries, and or civilizations. What are the rules? How are we, the most complicated form of life that we know of, suppose to act towards one another. The panoptic system has implemented itself upon the world. It has created a system where no one
