In this paper, we look backwards to educational development principles and practices as implemented in the 1990s at Chalmers University of Technology, Sweden, and forward to ideal principles and practices for the design of courses for teachers in higher education. The bridge between the two lies partly in an evaluation study, which we will describe, and partly in the theoretical work of John Bowden on knowledge capabilities for learning for an unknown future. The underlying framework depends on phenomenography, with its theoretical emphasis on learning as becoming able to discern the whole from its background, and how the constituents of the whole relate to one another and to the whole, and its empirical emphasis on qualitative variation in the ways in which students understand, conceptualize or experience phenomena they meet in their studies. A PET model and PET process are described, relating Practice, Experience and Theory through reflective problematization.  相似文献

The research is an investigation of teachers’ experience of working with socio-scientific issues (SSI). A large group of teachers (55) chose one of six cases with the characteristics of SSI and were free to organize the work as they found appropriate. The research focuses on how teachers chose content, organized their work and experienced the students’ interest and learning. The teachers answered a questionnaire after working with the cases and seven of them were interviewed to provide in-depth understanding of issues raised in the questionnaire. The teachers found the SSI to be current topics with interesting content and relevant tasks and they felt confident about the work. They were quite content with the students’ learning of scientific facts, how to apply scientific knowledge and to search for information. However, they found that the students did not easily formulate questions, critically examine arguments or use media to obtain information about the task. The interviewed teachers did not find this work new, but they organized it as ‘a special event’. They understood SSI work as ‘free’ work and group work was frequent, but only a few of the teachers developed explicit strategies for teaching SSI. They had different ideas about learning but they all talked about knowledge as a set of facts to be taken in by the students. They all included elements of SSI but mostly to introduce the regular science content. However the teachers started to reflect upon the potential of using SSI to cover more goals in the curriculum.  相似文献

There have been numerous anecdotal reports of an improvement in reading in dyslexic children fitted with tinted spectacle lenses. Few of these cases have been subjected to any sort of scientific scrutiny. We report the findings in two dyslexic brothers each of whom showed a marked improvement in reading facility when reading print material either through a semi-transparent tinted plastic sheet (overlay) or through tinted spectacle lenses. Other observed effects of the tinted overlays and/or tinted lenses were improved visual acuity, improved figure/ground perception and reduction in apparent distortions and fragmentation of print. Such improvements were noted in either one or both of the boys. A speculative explanation for this effect is that the lenses act by altering the transmission of impulses along the primary visual pathway.  相似文献

Enhancing the quality of argumentation in school science   总被引:1,自引:0,他引:1  
The research reported in this study focuses on the design and evaluation of learning environments that support the teaching and learning of argumentation in a scientific context. The research took place over 2 years, between 1999 and 2001, in junior high schools in the greater London area. The research was conducted in two phases. In phase 1, working with a group of 12 science teachers, the main emphasis was to develop sets of materials and strategies to support argumentation in the classroom, and to support and assess teachers' development with teaching argumentation. Data were collected by video‐ and audio‐recording the teachers' attempts to implement these lessons at the beginning and end of the year. During this phase, analytical tools for evaluating the quality of argumentation were developed based on Toulmin's argument pattern. Analysis of the data shows that there was significant development in the majority of teachers use of argumentation across the year. Results indicate that the pattern of use of argumentation is teacher‐specific, as is the nature of the change. In phase 2 of the project, the focus of this paper, teachers taught the experimental groups a minimum of nine lessons which involved socioscientific or scientific argumentation. In addition, these teachers taught similar lessons to a comparison group at the beginning and end of the year. The purpose of this research was to assess the progression in student capabilities with argumentation. For this purpose, data were collected from 33 lessons by video‐taping two groups of four students in each class engaging in argumentation. Using a framework for evaluating the nature of the discourse and its quality developed from Toulmin's argument pattern, the findings show that there was improvement in the quality of students' argumentation. This research presents new methodological developments for work in this field. © 2004 Wiley Periodicals, Inc. J Res Sci Teach 41: 994–1020, 2004  相似文献

This article shows how the Genre Teaching Methods developed in Australia can be adapted to the study of literature in secondary English classrooms. The theoretical position taken by those in Australia needs to extend beyond the textual focus to take account of the processes and culture of the reader and writer. It will be seen how the genres of Narrating, Describing, Explaining and Arguing can be used to analyse specific features of literature analysis - plot, character, setting, theme and style. Modelling texts and providing scaffolds for pupils' writing are a part of the systemic and structured approach to ensure progression and understanding in pupils' writing about English literature.  相似文献

Serial naming speed and its association with reading ability was examined in a longitudinal investigation. Participants were 68 children aged between 4.0 and 4.5 years when the study began and between 5.0 and 5.5 years when the study ended. Serial naming speed was measured at three equidistant time points over the 12‐month period as children progressed from a pre‐literate to early‐literate stage. Children's responses were digitally recorded to computer to enable analysis of the sound files. During analysis, the articulation time for each word and the length of each pause between the spoken words were measured independently. At the end of the study, children's word‐level reading ability was measured. Results suggest that children aged 4.0 to 5.5 years show wide variability in serial naming speed that is predominately attributable to the length of the pauses between the articulated words. There appears to be a developmental association between the duration of the pauses and word‐level reading ability.  相似文献

The surge of interest in evidence-based interventions necessitates MSW graduates who will pursue research activities in the workplace. However, evidence suggests that social workers tend not to use their research skills after graduation. This study examined three constructs that inform students’ relationships to research: (a) confidence in research skills, (b) academic activities that stimulate students’ interest in research, and (c) anticipated outcomes from future involvement in research activities. The findings suggest that MSW programs need to extend research training beyond the classroom by providing holistic research learning environments that clarify the role and purpose of research for the social work profession and provide opportunities for students to transform didactic research training into practical research skills.  相似文献

This article reports the outcomes of a project in which teachers' sought to develop their ability to use instructional practices associated with argumentation in the teaching of science—in particular, the use of more dialogic approach based on small group work and the consideration of ideas, evidence, and argument. The project worked with four secondary school science departments over 2 years with the aim of developing a more dialogic approach to the teaching of science as a common instructional practice within the school. To achieve this goal, two lead teachers in each school worked to improve the use of argumentation as an instructional practice by embedding activities in the school science curriculum and to develop their colleague's expertise across the curriculum for 11‐ to 16‐year‐old students. This research sought to identify: (a) whether such an approach using minimal support and professional development could lead to measurable difference in student outcomes, and (b) what changes in teachers' practice were achieved (reported elsewhere). To assess the effects on student learning and engagement, data were collected of students' conceptual understanding, reasoning, and attitudes toward science from both the experimental schools and a comparison sample using a set of standard instruments. Results show that few significant changes were found in students compared to the comparison sample. In this article, we report the findings and discuss what we argue are salient implications for teacher professional development and teacher learning. © 2013 Wiley Periodicals, Inc.

An ongoing research project has been focusing on the changing roles of colleagues based both in school and in college who are involved in the supervision of students in school and on their professional development needs.

This article focuses on three elements of the research findings which we have obtained from the collation and analysis of the evaluations of the programmes so far. box Aspects of the training which have been most useful

box Issues arising from the meetings of the mentor support groups

box Implications for the continuing professional development and career development of the mentors

The findings have been further informed by a series of semi‐structured interviews.  相似文献
