Self-regulatory strategies of goal setting and goal striving are analyzed in three experiments. Experiment 1 uses fantasy realization theory (Oettingen, in: J. Brandstätter, R.M. Lerner (Eds.), Action and Self Development: Theory and Research through the Life Span, Sage Publications Inc, Thousand Oaks, CA, 1999, pp. 315–342) to analyze the self-regulatory processes of turning free fantasies about a desired future into binding goals. School children 8–12 years of age who had to mentally elaborate a desired academic future as well as present reality standing in its way, formed stronger goal commitments than participants solely indulging in the desired future or merely dwelling on present reality (Experiment 1). Effective implementation of set goals is addressed in the second and third experiments (Gollwitzer, Am. Psychol. 54 (1999) 493–503). Adolescents who had to furnish a set educational goal with relevant implementation intentions (specifying where, when, and how they would start goal pursuit) were comparatively more successful in meeting the goal (Experiment 2). Linking anticipated situations with goal-directed behaviors (i.e., if–then plans) rather than the mere thinking about good opportunities to act makes implementation intentions facilitate action initiation (Experiment 3).  相似文献

This article is the first of two that will examine the claims of contemporary sociology of scientific knowledge (SSK) and the bearing of these claims upon the rationale and practice of science teaching. It is maintained that if the claims of SSK are true then there are serious, and educationally and culturally deleterious, implications which follow. The two articles will argue that, fortunately, the claims of SSK for the external causation of scientific belief are baseless. And thus science teachers should resist admonitions to accept the findings of the sociology of science.

I look forward to the day when the last proponent of the strong program in the sociology of science is strangled in the entrails of the last expert in the theory of metaphor

There has been a disturbing decline in the take-up of physics within second-level education in Ireland since the early nineties. Here, an analysis is presented of the main factors influencing the take-up of physics from the perspective of secondary school teachers. The database underpinning the analysis is based on a comprehensive survey of teacher opinion in Irish schools conducted in December 2004. The sample included all such schools in Ireland and was directed at school principals, senior cycle physics teachers, and junior cycle science teachers. The data reveal that most senior cycle physics teachers in Ireland do not possess a ‘physics-dominated’ primary degree, are dissatisfied with the technical back-up available to them and their students, consider that many of their students lack the basic mathematical skills needed for physics, believe their students are not adequately informed about career opportunities in physics, and feel students are disadvantaged in regard to grade points in the leaving certificate examination compared with most other subjects. These findings echo those of a previous report by the Government Task Force on the Physical Sciences and lend renewed urgency to the necessity of implementing a comprehensive action programme to reverse the decline in physics take-up before it impacts negatively on the Irish economy.  相似文献

An important purpose of internships in teacher preparation programmes is to develop competence through experience. The research questions in the present study concern student teachers’ interpersonal profiles (i.e. patterns of their interpersonal behaviour as perceived by students) and the accuracy of their self-belief regarding the interpersonal relationship with students at the beginning and end of the internship. Participants were student teachers (n=34) of a one-year teacher education programme. There were fewer student teachers with preferable interpersonal profiles at the end of the internship than in the beginning. Self-beliefs at the beginning indicated that the majority of student teachers were underestimating themselves; at the end of the internship most of them were overestimating themselves. About two-thirds had more accurate self-beliefs at the end of the internship than at the beginning. Overestimating oneself seemed negatively related to more accurate self-beliefs at the end of the internship and student teachers with more preferable profiles had more accurate self-beliefs.  相似文献

The problem addressed by this study is that first-year college chemistry students learn little of the conceptual material associated with chemistry experiments they perform. The thesis of this research is that the construction of prelab and postlab concept maps help students understand the concepts involved in the experiments they perform. The study was conducted using 32 non–science majors enrolled in a first-year chemistry course. The experimental group constructed prelab and postlab concept maps, while the control group wrote essays explaining the conceptual chemistry of the four experiments used in this study. Both groups took 25-item achievement tests 1 week after each experiment. Prelab and postlab concept maps were scored and evaluated for significant differences. Five students were interviewed to investigate their perceptions regarding the usefulness of concept maps in chemistry laboratories. No significant differences were found between treatment groups with respect to students' conceptual understanding as determined by the multiple choice achievement tests. Students responded very positively toward the use of concepts maps in the laboratory. They felt strongly that constructing prelab and postlab concept maps helped them understand the conceptual chemistry of the experiments. © 1998 John Wiley & Sons, Inc.

The use of circle time is becoming increasingly widespread in this country, but what exactly it involves and should achieve is subject to a wide range of interpretations. Such a situation can make the identification of what should count as good or appropriate practice very hard to undertake. This paper describes three examples of the development of circle time in other countries. These models are used as a means of critically reflecting on practice here. Some key points raised are the importance of the relationship between theory and practice and between specific processes and their outcomes. Lack of evaluative research and adequate training are also identified as significant issues.  相似文献

Research findings on class size differences need to be examined carefully because of their far reaching pedagogical and resource implications. An examination of research on the possible causal effect of class size differences on pupil progress, and on possible mediating factors, also raises important issues for educational research in general. In this chapter critically different approaches to research on class size effects are reviewed and an approach used in current research at the Institute of Education, that seems most likely to inform this controversial topic is described. Researchers need to pay more attention to providing a more reliable and valid measure of class size itself. In keeping with the bulk of research in this area the emphasis is on quantitative approaches, although possible limitations and alternative research approaches are considered. Limitations of earlier cross sectional research are examined, and the well-known STAR research is used to highlight some limitations of experimental designs. Finally, the advantages of longitudinal research, using multi-level modelling techniques, are examined.  相似文献

There are signs that teams are becoming more popular in ethnographic research. New technology and, in the UK, the Research Assessment Exercise have facilitated the establishment and continuance of teams. In this paper, the authors discuss their experiences in one particular research team in recent years. Securing adequate funding has been the essential structural prerequisite. The authors distinguish among project, federated, and whole teams, depending on function and level of analysis. They consider team structure, approach, business, and processes, and the relationship between individual and team. Teamwork has enabled a wider and deeper coverage of work, a broader comparative base, and multiple researcher triangulation. The team provides a forum for the discussion of ethical issues, an immediate supportive reference group. It has opened up horizons, and promoted individual change and development. It has aided analysis and writing, and promoted clearer and more robust arguments. The article concludes with some caveats.  相似文献
