The ethnomethodological programme of studies of work is drawn on to provide a general framework within which we might develop ways to undertake thein situ analysis of the competencies which constitute student learning activities. The objective of such research is to describe the locally managed and temporally organised nature of student learning work. Emphasis is placed on the development of methods of investigation which will enable us to describe the whatness of the work from within the setting of that work's accomplishment. The twin conceptions of the visibility and sequential order of student activities are discussed in detail. The implications of this approach for the notion of student learning are also examined.  相似文献

Large scale computer-assisted instruction systems generally impose severe constraints upon the demands that individual users may make. Nevertheless, it is possible to overcome these problems and a program is described which teaches students how to fly a specific maneuver through real-time simulation of the flight of a student-controlled airplane. This is achieved in spite of the fact that the student is flying his plane through the use of a manually controlled analog input device. Both computational and educational implications are discussed.Contractual support for this work was provided in part by the Life Sciences Program Air Force Office of Scientific Research, Contract number F44620-70-C-0105.

If Whitehead is right, science teachers who try to increase student interest by making the science they teach more pure and by covering more material are going about their work in just the wrong way. Science, for purposes of precision in measurement, translates the dynamic world of feeling and force, of causal efficacy (for example, the San Francisco earthquake), into a static representation spatialized and given presentational immediacy (for example, the Richter scale). But notice that the Richter scale isn't very interesting (even as abstract art) apart from its connection, via symbolic reference, to the earthquake. Such reference is essential to give both a sense of reality and a feeling of interes to the subject, but it makes the science less pure, and it takes more time to cover the material. An example of teaching pure and impure formal logic is given as a case study.  相似文献

This study investigated HyperCard as a tool for assessment in science education and determined whether or not a HyperCard assessment instrument could differentiate between expert and novice student performance (balancing stoichiometric equations) in science education. Five chemical equations were presented by traditional pen-paper and by a HyperCard (Hyperequation) program. Thirty honors (expert) and 30 regular (novice) chemistry students were randomly divided into HyperCard and traditional pen-paper groups of 15 students each. Scoring was based on five dependent variables: performance scores, number of attempts, rate of attempts, time on task, and correctness. Correlation results indicated that students with high performance scores correctly balanced more equations, required fewer attempts to balance equations, and required less time per attempt than did students with low performance scores. MANOVA results showed that performance scores and correctness scores for both experts and novice were significantly higher on HyperCard compared to pen-paper assessment; the novice scores on HyperCard nearly equaled the expert pen-paper assessment scores. Significant interactions were found for time on task and for correctness. The results suggest that HyperCard can be a suitable tool for assessment in science education and that such an instrument can differentiate between expert and novice student performance.  相似文献

A two-dimensional analysis of student ratings of instruction   总被引：2，自引：1，他引：2  
Student ratings of instruction were analyzed in terms of two global factors. One factor, which includes items on advanced planning, presentation clarity, and increased student knowledge, was named pedagogical skill. The other factor taps information about class discussion, grading, and the availability of help and was named rapport. Ratings on the skill factor did not covary with class size or the leniency of the instructor's grading but did correlate with a reasonable external criterion of student learning. Ratings of rapport correlated inversely with class size and directly with average class grade and showed only a weak relationship to the external criterion of student learning. The skill factor showed more interclass stability than the rapport factor. Previous research studies which have examined the reliability and validity of instructional ratings and their relationship to student grades and class size have reported inconsistent findings. These inconsistencies appear to result from an inappropriate unidimensional analysis of ratings which should be examined in terms of two of more separate attitude dimensions.  相似文献

What began as a case study of intergenerational initiatives in university-based early childhood programs evolved into a comparative study of two different program implementation processes. Despite operating with the same goals, university partners, and resources, two early childhood centers pursued fundamentally different strategies for launching their intergenerational programs. One site followed what we call an explicit intervention with a set timeline and series of planned steps for finding, placing, and involving seniors in classroom activities. The other pursued what we call an emergent (or organic) strategy with no predetermined plan for finding senior volunteers and integrating them into classroom activities. Drawing on data collected from interviews with program staff and parents, and observations of intergenerational activities, this study serves to describe, compare, and contrast these alternative program initiation strategies. Both models are effective, but represent different approaches to valuing the contributions of older adults in the lives of young children.  相似文献

Inauguration of double-shift junior secondary schooling in Trinidad and Tobago in 1973 created several problems for local planners, policy makers, parents, and students themselves. In some cases solution has been found, but in others problems have remained defiant and irresolute. In the latter category is the problem of deviant student behaviour during off-shift sessions, believed to be the result of poor student choice regarding the use of time. Recommendations have been made to redress this situation through engagement of community groups. This paper argues that this approach is problematical and contradictory and will not achieve stipulated objectives. The main reason for the gloomy outlook is the principle of decentralization, which must be taken into account in any attempt to engage the local community. Community engagement is examined against certain imperatives of decentralization. The paper concludes, however, that as a strategy, community engagement is doomed to failure. Poor choices by junior secondary school students in the use of their off-shift hours are therefore very likely to persist.  相似文献

On the nature of problems   总被引：2，自引：0，他引：2  
This paper is an attempt at clarifying the concept of problem, and originates from a concern for improving the teaching of problem solving.The following categories are identified and employed in the analysis of several examples of problems and related notions: (a) the formulation of a problem, i.e. the definition of the task to be performed, (b) the context in which the problem is embedded, (c) the set of suitable solutions, (d) the methods of approach that could be employed in solving the problem.Commonalities as well as contrasts among specific examples are used to identify important elements of problems. The study suggests a possible classification of types of problems of educational interest, and draws some implications for the choice and use of problems in classroom instruction.  相似文献

One of the main differences between novice and expert problem solving in physics is that novices mostly construct problem representations from objects and events in the experimental situation, whereas experts construct representations closer to theoretical terms and entities. A main difficulty in physics is in interrelating these two levels, i.e. in modelling. Relatively little research has been done on this problem, most work in AI, psychology and physics education having concentrated on how students use representations in problem solving, rather than on the complex process of how they construct them. We present a study that aims to explore how students construct models for energy storage, transformation and transfers in simple experimental situations involving electricity and mechanics. The study involved detailed analysis of problem solving dialogues produced by pairs of students, and AI modelling of these processes. We present successively more refined models that are capable of generating ideal solutions, solutions for individual students for a single task, then models for individuals across different tasks. The students' construction of energy models can be modelled in terms of the simplest process of modelling — establishing term to term relations between elements of the object/event world and the theory/model world, with underlying linear causal reasoning. Nevertheless, our model is unable to take into account more sophisticated modelling processes in students. In conclusion we therefore describe future work on the development of a new model that could take such processes into account.1. CHENE = CHaîne ENErgetique, or Energy Chain. (In French Chêne also means oak).2. Throughout the rest of the paper we use the following simple notation in order to avoid possible confusion between modelling as a process performed by the students, in the domain of physics, and AI modelling of the former modelling process: students' modelling in physics = modelling SP ; AI modelling (of modelling SP ) = modelling AI .3. It has not been necessary to use more sophisticated strategies at the stage of our work reported here. The next system, modelCHENE, will directly address this issue.4. Note that what we refer to in this context as problem solving may in another context be viewed as construction of a qualitative representation for subsequent quantitative problem solving.5. The protocols indicate that students use this as a kind of anchor in their reasoning-some students returning to it in order to resolve impasses. As the current problem solver provides no mechanism for handling impasses we cannot model the reuse of information in any meaningful way.6. We are grateful to an anonymous reviewer for this example.7. This provides the minimum distinction for our initial needs.8. Though there is a difficult step in deciding that the moving object really is the last unassigned object-since that requires setting aside any need to assign roles to, for example, connecting strings etc.9. At the moment we have to provide psCHENE with slightly different rulesets: providing rules with priorities would be more convenient.  相似文献

summary This article presents a case study class response to Mildred Taylors now classic and widely read novel, Roll of Thunder Hear My Cry. Through data collected during one school year, the ways urban, adolescent students use their contemporary lenses to interpret the literary theme of confronting, overcoming and challenging racism are discussed. The participants responses are organized into four reader response categories that explicate the complex and interactive interpretations developed by the children while reading the novel. In addition to providing insights about the participants textual understanding, pedagogical findings indicate that the book can also be used to explore the nature of racism while creating a safe space to confront and more deeply understand racisms impact on the past as well as the students current reality.  相似文献

The term certification, as used in discussions concerning higher education, is clarified and a distinction made between terminal awards which do have a genuine certifying effect in the sense of procuring admission to a profession and those which do not. Institutions wishing to increase the value of the certifying effect of their awards, seek to do this by stimulating applications for entry to their institution. The longer the queue at the gate the greater the prestige of the terminal award. The ability to influence the certifying effect of an award does not, however, lie with the teaching institutions alone; business, the employers and the professions can, and increasingly do, determine the relative value of awards and of different ways of preparing for the exercise of a particular profession. The case of the business schools in France is described to illustrate how teaching institutions once they are established seek to increase the certifying effect of the diplomas they award by actually reducing the number of graduates. The numerus clausus, as applied to medical schools, provides another example of the same phenomenon. Such strategies lead to what the author describes as consumer effect. Once admittance to a prestige institution has been gained, entry to a position of influence and possibly affluence, is more or less assured. Students in such institutions, in both capitalist and communist countries, have exploited this by persuading teaching staff to acquiesce in a reduction of the demands made by the course, though some directors of institutions have begun to respond by failing more students, seeking to re-establish positions surrendered in the days of student unrest and by these and other means seeking to reduce consumer effect. Teacher training colleges provide an interesting example of institutions having a low but certain certifying effect, producing a high consumer effect. The possibility of deriving a general theory from the proposition put forward in the article is discussed.This is an improved version of an article published earlier in French: Effet certifiant et effet clientèle.

The paper analyzes the relationship between the epistemological nature of mathematical knowledge and its socially constituted meaning in classroom interaction. Epistemological investigation of basic concepts of elementary probability reveals the theoretical nature of mathematical concepts: The meaning of concepts cannot be deduced from more basic concepts; meaning depends in a self-referent manner on the concept itself. The self-referent nature of mathematical knowledge is in conflict with the linear procedures of teaching. The micro-analysis of a short teaching episode on the concept of chance illustrates this conflict. The interaction between teacher and students in everyday teaching produces a school-specific understanding of the epistemological status of mathematical concepts: the concept of chance is conceived of as a concrete generalization, which takes chance as a fixed and universalised pattern of explanation instead of unfolding potential and variable conceptual relations of chance or randomness and developing the theoretical nature of this concept in an appropriate way for students' comprehension.  相似文献

The Changing Debate on Internationalisation of Higher Education   总被引：3，自引：0，他引：3  
Internationalisation, the growing border-crossing activities between national systems of higher education is losing ground to globalisation, increasing border-crossing activities of blurred national systems which is often employed to depict world-wide trends and growing global competition. This article addresses recent issues of knowledge transfer. It points out tensions between increasing diversity in higher education and efforts to facilitate recognition of prior studies on student mobility. It shows the diversity of steering and management policies with respect to internationalisation and globalisation. Finally, it asks whether globalisation of higher education has to be viewed as a manifestation of turbo-capitalism or could be viewed instead as a move towards global understanding.  相似文献

The goal of this study was to develop a framework for classifying algebra story problems and to determine observed frequencies for each problem type. A total of 1097 algebra story problems were selected from ten standard algebra textbooks. These are divided into eight families based on the nature of the source formula involved; for example, nearly 300 problems were classified in the time rate family because they were based on the source formula, distance = rate x time or output = rate x time. Each family was divided into problem categories based on the general form of the story line; for example, the time rate family consisted of motion, current, and work categories. Each category was divided into templates based on the specific propositional structure of the problem; for example, there were a dozen templates for motion problems such as overtake, closure, round trip, etc. This article describes the procedure for generating families, categories, and templates and provides frequency counts for each observed template. Implications for fostering productive research and instruction are discussed.This research was supported by grant NIE-G-78-0162 from the National Institute of Education.

This statistical study of Canadian university presidents was prompted by the discovery that there is no systematic demographic information available on university administrators in Canada. The vitae of 98 current Canadian university presidents and their immediate predecessors were collected and statistics such as age and length of tenure were compared with those of American counterparts. The Canadian university presidents assumed office at about 49 years of age and held office for about eight years. They tend to be born in geographical proximity to the institution they will head and to circle it geographically during their careers. A former association with the University of Toronto, either as a student or teacher, was common. There appears to be a career ladder which includes a decanal and/or vice-presidential position, particularly in central Canada; few presidents move to a second presidency, although several move into what might be termed an academic superstructure. Few Canadian presidents majored in the field of Education as a student or teacher and there is generally poor representation from the Arts as compared to the U.S.; on the other hand, the hard sciences are well represented. The implications of these tendencies are discussed.  相似文献

Drawing upon Freud's seminal discussion of psychological identification vis-a-vis group psychodynamics, this study investigated the relationship between degree of student identification with an instructor and students' ratings of instructional effectiveness. Specifically, it was hypothesized that students who highly identify with their instructor will rate the course more favorably, perceive greater progress on their part toward course related objectives, and report higher motivation to learn than students who do not identify with their instructor. Using a 50 item personality trait Q-sample, 96 undergraduates from eight different courses taught by three different instructors were asked to describe the instructor, their actual self, and their ideal self; Q-sorts for the instructor and ideal self were correlated separately for each student as the measure of identification. Instructional effectiveness was assessed using the Kansas State IDEA form. Correlational and path analyses of the data provided support for the hypothesis. Results are discussed in light of the unique contribution made by the traditional notion of identification to instructional outcomes and evaluation.  相似文献

This paper describes a year-long study of the way a group of six 12-year-old children went about solving a special class of geometric problems, using a computer and a limited set of Logo programming tools. We examined children's solution strategies from the perspective of whether the strategies led to insights about the underlying mathematical relations. It was found that the feedback aspect of the computer graphics screen encouraged solution strategies that were qualitative and driven by visual data, rather than being based on explicit or implicit relations. These visually based strategies did not lead to the kind of mathematization of problem-situations that we as mathematics educators would like to see and, in fact, seemed to be a barrier to the development of higher levels of geometric thinking.  相似文献

Insofar as the basic concepts (in particular, meaning, interpretation, text) and theses of Martin Eger's hermeneutics of the sciences are intelligible they are not distinctive, and insofar as they are distinctive they are unintelligible and/or lack backup arguments. Ambiguity characterises much of the argument. James Cushing's elaboration of hermeneutics, using the history of quantum mechanics as an illustration of its supposed strengths, does nothing to rescue the position against the criticisms here levelled at Martin Eger's formulations of it.  相似文献

The thesis of this paper is that it is a productive venture to introduce preservice students to social theories that are typically not a part of teacher preparation programs. Examples of these theories are those associated with terms such as habitus, the carnivalesque, power / knowledge, seduction, detournement, the spectacle,la perruque, (the wig), and the art of making do,as well as others. In this paper, I describe a project that involved exploring the theory of habitus to problematize the tendency of preservice students to not think in terms of relations between what goes on in the classroom and what goes on in society. I introduced habitus by having preservice students read selected print materials and by having them view, analyze, and respond in writing to popular school films. Students also analyzed their experiences in classrooms in terms of habitus, making a connection between theory and practice.  相似文献

The errors made when high-school students locate reflections in horizontal, vertical or slanting mirrors were examined. A questionnaire consisting of thirty-six perspective drawings, each portraying an upright transparent cube containing a two-sided mirror, was given to 394 Australian students from grades 7, 9 and 11. On a corner, an edge, or a face of each cube was drawn either a point or a straight-line segment. The task was to draw its image (reflection). Analysis of errors revealed a strong tendency towards horizontal or vertical sliding, suggesting that the edges of the cube act in much the same way as a horizontal-vertical background grid does in the two-dimensional case.  相似文献
