Strategies implemented by 12–13 year olds to solve electricity problems are examined. Three factors account for observed strategies:
  1. type of problem representation, itself dependent on the knowledge base;
  2. cognitive personality dimensions;
  3. form of problem statement.
Individual interviews were conducted. Each problem statement contained a perceptual ‘trap’ designed to induce contradictory responses. Strategies were coded for accuracy, latency, justification and control. Five types of problem solving strategies were observed:
  1. a strategy based on misconceptions such as the vanishing current model;
  2. a similar strategy but greater verbalization of doubt;
  3. rush to use formulas;
  4. sequential analysis of circuit;
  5. application of principles learned in class.
Analysis shows that the target problems fell into two classes: problems that triggered automatic (canonical or calculatory) responses, and problems which were much more disruptive. The latter differentiated students who could handle contradictions and control their responses. Mention is also made of difficulties caused by the signified/signifier relationship.  相似文献

Based upon a nation wide campaign called Public Private Partnership—Schools in the Net (PPP-SiN) (Public Private Partnership—Schule im Netz (PPP-SiN), 2000) we were able to initiate an externally financed project of in-service teacher education. The paper describes the realization of this project. Reflections are given on why teachers hesitate to integrate ICT into their teaching. Media competencies are recognized to be key in this context. We reflect upon the following five questions:
  1. How do we educate the right thing as well as educate the right way?
  2. Which ambient conditions must be met?
  3. Which preliminary actions have to be taken and implemented?
  4. Which tools, methods and instruments do we need?
  5. How do we make sure that the transfer of learned knowledge will take place to find its way into successful teaching?

In this article I describe three key design issues which underlie a CIRG project building an open learning hypertext package for teaching writing skills. These are issues in:
  • ? combining flexible materials with fixed structures;
  • ? giving students real flexibility in learning;
  • ? the nature of interaction in hypertext writing teaching.
  • I outline a design strategy to meet problems in all these areas.  相似文献

    This paper presents results of research concerning the construction of the concept of natural integers by children. By testing the same children, whose school history was known with accuracy, at one year in tervals, we have sought to determine:
  • — How their competence in counting and numeration evolved during this period.
  • — What the mechanisms of this evolution were.
  • — What role school learning played.

    This article examines factors affecting the development and implementation of Education Policy with special reference to the 1981 Education Act for England and Wales. Research is reported about professional practice and administrative behaviour in special education assessment. Six professional and administrative factors are identified which may affect the implementation of the new special education legislation:
    1. The nature of the professional domain of special education assessment;
    2. The emergence of competing definitions of special educational need and good practice;
    3. The concern for professional and administrative accountability;
    4. The concern for the rights of users of special education provision;
    5. The politicisation of special education through the development of interest groups;
    6. The market relations between supply and demand in special education provision.

    Two related problems have to be solved before we can have a clearer picture of cognitive development:
    1. Is development hierarchical, leading to higher-order systems controlling lower-order subsytems?
    2. If so, what are the mechanisms involved in a process of development?
    These two problems will be studied here taking as example a concept which finds its achievement only in late adolesence: the concept of proportion. Part I of this article is devoted to the first problem. It will bear on the experiment which was undertaken and the analysis of results leading to a differentiation of stages of development. These stages will be illustrated by typical protocols of each stage. Part II will be devoted to problem solving strategies at each stage, and finally to a second order analysis leading to an attempt to interpret the passage from one stage to the next in terms of increasing equilibration or adaptive restructuring of the strategies put to use to solve problems.  相似文献

    Two basic points are made in this article:
  • -We must make a choice whether we ‘isolate’ people from or ‘include’ people in our communities. Including people is the only viable option.
  • -The key to ‘including’ people is with the very people we most often label as ‘the problems’. These ‘problem people’ can help generate answers when we learn how to listen, and when we offer genuine learning opportunities and valid partnerships with those who have been ‘missed’ and discarded.
  • Examples from various Frontier College programs illustrate these points and elaborate the central philosophy of the College (Student Centred Individualized Learning — SCIL), which is based on the beliefs that:
  • -All are welcome
  • -All belong
  • -All can learn
  • -All have contributions to make
  • The programmes are focused on ‘literacy’, which is a great deal more than reading and writing — it is about what kind of society we want. Literacy is a tool for ‘inclusion’ in communities. It is hard work, and includes love and tears, grief and joy, families and friends. It is based on the Right to Learn, and builds dignity, self esteem and choices.  相似文献

    Guidance and counselling services, which were introduced to Nigeria in 1959, have recently undergone rapid growth. While the approaches of the formalized guidance services have been largely Western, traditional means of approaching an individual's problems have always existed within Nigerian communities. This article identifies areas of traditional counselling that might be used alongside those of the Western system. The special areas examined were those of mural guidance, vocational counselling, marriage counselling and emotional counselling. Findings include the following:
    1. Every adult in the society who possesses relevant experience in any problem area is capable of playing the role of a counsellor at least for that particular problem.
    2. An individual who is considered in need of guidance is invited into counselling.
    3. The early knowledge that work is essential for every adult provides individuals with appropriate skills of choosing satisfying vocations.
    4. Individuals proposing marriage undergo counselling.
    5. Divination offers a reassuring approach to counselling situation.

    Asian students in increasing numbers have over the postwar period decided to go overseas for tertiary education, and an increasing proportion of those overseas students have selected the United States as their place of study. Eight elements of the changing context of Asian-American relations are identified which influence the Asian preference for American higher education:
    1. The improving Asian-American political links
    2. The increased volume of Asian-American economic exchange
    3. The sharp increase in Asian immigration to the United States
    4. The increasing similarity in the structure and content of Asian and American educational systems
    5. The absorptive capacity of American higher education
    6. The quality of American higher education
    7. The complementarity of Asian demand and American supply
    8. The opportunities provided in American higher education to cover educational costs through part-time work

    A survey commissioned by the French Ministry of Education on mastery of the French language by the end of the elementary grades (11–12 years) was conducted on a sample of 4585 students. The data was used to compare the results obtained on tests of written French designed to measure level of acquisition with ministerial guideline objectives. Three types of analysis were performed, to attempt to define:
    1. a pattern of results between grammatical exercises
    2. a pattern of results between exercises about use of the French language in context
    3. the relationships between grammatical acquisitions and use of language in context.
    Two issues arise from this analysis: first, the problem of the relationships between the way the elementary school student analyses language through intuitive understanding of meaning vs rules of formal analysis; and second, the problem of transfer mechanisms which allow information learned in one language situation to be applied to new situations.  相似文献

    This study deals with the observation of a class composed of children aged 8–9 solving division problems. The analysis aims at differentiating the attitudes of pupils confronted with situations resulting from ‘EMPIRICAL’ learning from those observed in situations involving action resulting from ‘DIALECTIC’ learning. Two learning sequences are described in the course of the study:
  • * The first includes four classical terms which allow the use of empirical methods to find the quotient and the remainder.
  • * The second includes two terms elaborated so that they favour a dialectic of action with the children.
  • The observed differences reveal that:

  • * The repetition of drills of the same nature during the first learning sequence does not result in important variations as far as success and solution procedures are concerned.
  • * On the other hand, during the second learning sequence, all pupils use a more economical solution procedure with high level success rate.

    When and whay children change tense subsystem in a written text? 89 French and German pupils and 90 Catalan pupils aged 10, 12 and 14 produced each a fairy-tail, a short news item and a letter. The analysis of tense subsystem alternations in these texts reveals:
    1. that the factors explaining alternations are the same in the observed languages
    2. that in some cases, alternations are errors induced by the difficulty to master different enunciative levels in the text
    3. that most alternations create sense effects in relation to text structure, but since very often no other linguistic unit reinforces the effect created, it may lead to some ambiguity for the receiver.
    Nonetheless, the results show that alternation of tense subsystem can be seen as an emerging textual competence.  相似文献

    On September 7, 1983, the U.S. Department of Education announced a nationwide adult literacy initiative designed “... to promote functional literacy for the entire adult populations.” The department is committed to conducting several activities to attack and solve the problem of adult literacy. Two of the activities pertain specifically to postsecondary education. They are:
  • ? working with postsecondary education institutions to develop demonstration programs utilizing college work-study students in adult literacy programs;
  • ? promoting college student involvement through literacy tutoring experiences in college courses and through student volunteerism.
  • The authors believe that there should be much greater participation in the initiative by postsecondary education institutions, and they propose that more extensive participation can be attained through the institutions' performance of their usual functions of teaching, service, and research.  相似文献

    This study reports on grade 4 children’s (Ss) knowledge of constraints and characteristics of persuasive written requests (RQ).
    1. All Ss wrote a first RQ asking money to improve their computer lab.
    2. Experimental (E) and control (C) Ss evaluated 4 different RQ.
    3. selected and ordered, out of 30 scrambled sentences, those appropriate for a “good” RQ.
    4. A week later, E Ss had a collective “training discussion” on requests.
    5. A week later, E and C Ss wrote a second RQ asking money for their science lab.
    Results pertaining to different aspects of the produced RQ showed that the training did have some effects but both groups improved in their II RQ. The results were interpreted as suggesting that both groups actually learned what an appropriate request is by carefully evaluating the 4 requests and by constructing a request from a sentence list.  相似文献

    In teaching, representations are used as ways to illustrate the concepts underlying a specific topic. For example, use symbols (e.g., 1?+?2?=?3) to express the concept of addition. To compare students’ abilities to interpret different representations in mathematics, the symbolic representation (SR) test and the pictorial representation (PR) test were designed, and then administered to 681 sixth graders in Taipei, Taiwan. This study adopts two different modeling perspectives, the testlet perspective and the multi-ability perspective, to analyze this SR and PR test data in the context of item response theory. The main results show that:
    1. Students scored on average significantly higher on the SR test than the PR test.
    2. The effects of the item stem testlets could be large, but they are statistically non-significant; however, the influence of the number of items in the testlet should also be considered.
    3. The nature of the option representations, SR and PR, represents two different mathematics abilities.
    4. The main factor that influences students’ item responses is students’ abilities to interpret SR and PR, and the testlet effects generated from the shared item stem can be ignored.
    5. Regarding the parameter estimates of the best-fitting model: (a) the person ability variance estimates show that the ability distributions on the SR and PR dimension may not be the same, (b) the correlation estimate between the SR and PR dimension indicates that these two abilities are moderately correlated, and (c) the item difficulty estimates for different models are similar.
    Suggestions for teaching practice and future studies are provided in the Conclusion.  相似文献

    The ILO's World Employment Programme, launched officially in 1969, constitutes the major contribution of the International Labour Organisation to the Second Development Decade in the area of employment objectives and policies. The general aim of the World Employment Programme (WEP) is to provide concrete and specific guidelines to policy-makers and planners on policies and measures which enable them to choose those development strategies which have a greater weight attached to productive employment creation, and to assist in their implementation. The following activities have recently been undertaken to give practical effect to the World Employment Programme. First, so-called comprehensive employment strategy missions have been sent to Colombia, Ceylon, Iran and Kenya (ILO, 1970, 1971, 1972a, 1972b). In the light of a definition and diagnosis of the employment problem in these countries, these missions have proposed a long-term strategy based on fundamental changes in key areas of development policy, including education and training. They have also drawn up an immediate programme of action to face the most urgent problems. Second, regional teams have been established in Latin America and Asia, and several subregional teams are in the process of being constituted in Africa. Set up with a view to making a comprehensive investigation of employment problems in the countries of the region and assisting them in formulating employment policies and programmes, they are keeping under review the progress and obstacles encountered and identifying needs for further direct assistance. Third, a major research programme has been launched. The principal elements of the WEP's research programme are the following major projects which are currently being carried out or are about to start:
    1. population and employment;
    2. technology and employment;
    3. income distribution and employment;
    4. education and employment;
    5. international trade and employment;
    6. urban employment problems; and
    7. feasibility of emergency employment schemes.
    This article gives a brief account of the insights already gained and the work under way in the area of education and employment.  相似文献

    In June 1988, the SA Minister of Education announced the allocation of $650,000 to boost science and technology in State primary schools. Subsequent allocations have raised funding for Phase 1 and 2 of this ‘SCI-TEC Project’ to over $1m. This level of funding for science and technology in primary schools is unprecedented in Australia. During 1989 the Independent Schools Board sponsored a pilot project along similar lines and in 1990 the Disadvantaged Schools Program of the Catholic Education Office followed suit. Although different structures have been provided, an interactive approach to in-service has been the underpinning for all three projects. This paper examines what has happened in each of these projects so far, and reviews the strategies used to:
    1. develop interactive models of in-service education.
    2. involve teachers as effective change agents in their schools
    3. enhance the impact of focus teachers working in neighbouring schools
    4. record the insights of all participants in the projects
    5. maintain accountable procedures when using a model of in-service which rejects a ‘top-down’ approach.

    Today’s societies place challenging demands on individuals, who are confronted with complexity in many parts of their lives. What do these demands imply for key competencies that individuals need to acquire? Defining such competencies can improve assessments of how well prepared young people and adults are for life’s challenges, as well as identify overarching goals for education systems and lifelong learning. Why are competencies so important today? The PISA 2000 results underline the importance of student engagement. PISA found strong relationships between students’ attitudes, learning strategies and performance. In addition to skills related to specific parts of the school curriculum, students need to be equipped with some general competencies to solve life’s challenges. As they progress to adulthood, they need to learn to be able to complete not just pre-rehearsed exercises, but must also be able to solve problems set in unfamiliar situations by thinking flexibly and pragmatically. PISA 2003 therefore made a first-time assessment of students’ problem-solving skills. Findings revealed that just under one in five 15-year-olds in OECD countries are ‘reflective, communicative problem solvers’ able to tackle difficult tasks and also just under one in five students have problem-solving skills that cannot even be classified as ‘basic problem solvers’. What could be the basic problem and what resolution can be sought for? There are several examples in learning theory that suggests promises which need to be revisited. Barr and Tagg [From teaching to learning. Change. November/December pp. 13–25. Retrieved June 15, 2006 from http://critical.tamucc.edu/~blalock/readings/tch2learn.htm, 1995] defined the differences of paradigms in terms of learning theory comparing the notions of ‘teaching’ and that of ‘learning’, obviously expressing preferences to the later for its more in-depth effect on the learner. One of the main learner-centric approaches providing adequate positive results is problem based learning (PBL). This paper revisits the pedagogic theory behind PBL and examines it through a practical case study of a TeaM challenge game [TeaM challenge games: http://kihivas.ini.hu] with respect to its value in teacher education. It will concentrate on issues centred around:
    • Traces of use of higher order thinking skills—according to Bloom’s taxonomy.
    • Pedagogic pre-assumptions (designer’s side): requirements for design and supposed impact of students and teachers.
    • Assignment within teacher training (training side): as the task of setting up such game is performed within Informatics teacher training at ELTE University and games were launched into public education.
    • Pedagogic realities (facilitator’s side): how the teachers at a specific participant school viewed their role, the game, its impact and pedagogic value, its role in fulfilling the National Curriculum and its benefit for students.
    • Indirect impact (staff’s side): how the game has affected the whole staff at school and what impact it had of the attitude of teachers.
    • Results (evaluator’s side): how the game was evaluated in several ways and what new methods it has introduced into public education.

    This study is concerned with the problem of perspective planning of education. First it considers the underlying conception of the educational system, indicating what are the essential factors in Hungary's national education. The authors then seek, by means of a systems theory conception to give this education a place in society, and in civilization — bearing in mind that national education is “a system of relative independence”. From here they go on to examine the patterns imposed by planning for perspective development. An important section examines planning as a process and considers it as an essential concomitant of the strategy of development in the following phases:
    1. the politico-scientific process of formulating the conception.
    2. the process of checking the continuing validity of the conception.
    3. the decision-making process by which the conception is accepted.
    4. the process of initiating and implementing the conception.
    The thinking of practitioners of national education may come to regard planning as a permanent and continuing activity. A method of planning the process of continuing-development must be created on three levels, that of the great corporations concerned, that of regional directors, and that of experts in educational practice.  相似文献

    The problem of measuring instructional effectiveness was examined, and a rationale was offered for employing “student progress on relevant objectives” for this purpose. To assess such progress, it was suggested that instructor ratings of the importance of objectives be combined with student ratings of progress on these objectives. On the basis of this suggestion, data were collected from 708 undergraduate classes at Kansas State University. An analysis of these data resulted in the following conclusions:
    1. Faculty members appeared to make reliable judgments of the relative importance of these objectives.
    2. Student progress ratings were made with acceptable reliability when there were 20–25 raters. Reliability of the overall progress measure was satisfactory when only 10 raters were used.
    3. Students used some discrimination in rating progress on various objectives, but their ratings were also noticeably subject to the halo effect.
    4. An indirect test of the validity of class progress ratings yielded positive results.
    The proposed method of evaluating instruction appears generally feasible and useful. Its application would provide a practical approach to judging teaching success. Such an approach is essential before investigations can be undertaken of how teaching might be improved.  相似文献
