Videobased lesson analysis: Effective science PD for teacher and student learning     

Kathleen J. Roth  Helen E. Garnier  Catherine Chen  Meike Lemmens  Kathleen Schwille  Nicole I.Z. Wickler 《科学教学研究杂志》2011,48(2):117-148

The Science Teachers Learning from Lesson Analysis (STeLLA) project is a videobased analysis‐of‐practice PD program aimed at improving teacher and student learning at the upper elementary level. The PD program developed and utilized two “lenses,” a Science Content Storyline Lens and a Student Thinking Lens, to help teachers analyze science teaching and learning and to improve teaching practices in this year‐long program. Participants included 48 teachers (n = 32 experimental, n = 16 control) and 1,490 students. The STeLLA program significantly improved teachers' science content knowledge and their ability to analyze science teaching. Notably, the STeLLA teachers further increased their classroom use of science teaching strategies associated with both lenses while their students increased their science content knowledge. Multi‐level HLM analyses linked higher average gains in student learning with teachers' science content knowledge, teachers' pedagogical content knowledge about student thinking, and teaching practices aimed at improving the coherence of the science content storyline. This paper highlights the importance of the science content storyline in the STeLLA program and discusses its potential significance in science teaching and professional development more broadly. © 2011 Wiley Periodicals, Inc., J Res Sci Teach 48: 117–148, 2011  相似文献   

The disaster of the ‘self‐managing school’ – genesis,trajectory, undisclosed agenda,and effects     

John Smyth 《Journal of educational administration and history》2011,43(2):95-117

Sometimes an educational idea is inexplicably adopted around the world with remarkable speed and consistency and in the absence of a proper evidence base or with little regard or respect for teachers, students or learning. This paper examines what has arguably been the most contentious and virulent educational reform of the past half‐century. Variously labelled, in what amounts to the self‐managing school, what this reform has done is virtually dismantle public education and privatise it without public debate or proper scrutiny. This paper considers the alleged claims by the enthusiastic proponents and examines what has subsequently transpired, particularly in respect of the most disadvantaged students and the broader mission of improved learning.  相似文献   

The lost promise of teacher professional development in England     

V. Darleen Opfer  David Pedder 《欧洲师范教育杂志》2011,34(1):3-24

This paper explores three influences on the effectiveness of teacher professional development for improving schools – the individual teacher, the learning activities in which teachers participate and the structures and supports provided by schools for teacher learning. It does so by relying on survey data collected for a national study of teacher professional development in England. The analysis indicates that while the professional development of teachers in England is generally ineffectual and lacks school level systems and supports, the professional development and supports for professional learning by teachers in high performing schools display many of the characteristics associated with effective professional learning. Given the results showing a link between school factors and professional learning and the lack of influence of individual teacher factors, the paper concludes that the previously reported importance of school capacity in influencing learning and improvement is supported by the findings.  相似文献   

Research engagement and educational decentralisation: problematising primary school English teachers’ research experiences in China     

Xuesong Gao  Gary Barkhuizen  Alice Wai Kwan Chow 《Educational studies》2011,37(2):207-219

Teachers are encouraged to enhance professional competence through reflective practice and they are also asked to undertake research to generate evidence for their professional practices. This paper reports on an inquiry into a group of primary school English language teachers’ research engagement in the province of Guangdong on the Chinese mainland. The inquiry explored the effect of educational reforms on the participants’ research engagement through the use of an open‐ended questionnaire and group interviews. The inquiry revealed that research engagement had become an important part of the teachers’ professional lives. Emerging findings from the inquiry also problematised their research engagement as it was found to have been undermined by a competitive promotion mechanism, the teachers’ conceptualisations of research and challenges in the knowledge dissemination process. The paper ends with reflections on how to make teacher research “educational” for teachers and serve as an effective way for professional development.  相似文献

Team-based learning in anatomy: an efficient, effective, and economical strategy     

Vasan NS  DeFouw DO  Compton S 《Anatomical sciences education》2011,4(6):333-339

Team-based learning (TBL) strategy is being adopted in medical education to implement interactive small group learning. We have modified classical TBL to fit our curricular needs and approach. Anatomy lectures were replaced with TBL that required preparation of assigned content specific discussion topics (in the text referred as "discussion topics"), an individual self-assessment quiz (IRAT), analysis of the discussion topics, and then the team retaking the same quiz (GRAT) for discussion and deeper learning. Embryology and clinical correlations were given as lectures. Unit examinations consisted of graded IRAT and GRAT. The National Board of Medical Examiners (NBME) Subject Examination was the comprehensive final examination. To evaluate the effect of TBL on student performance we compared the departmental and NBME subject examination scores between the traditional and TBL curricula. We collected five years of data on student performance in TBL-based anatomy and lecture-based preclinical courses. Our results show that departmental and NBME subject examination scores for TBL-based anatomy were higher than those for lecture-based anatomy. We subsequently compared average NBME scores for anatomy with those in other preclinical courses that were lecture-based. Average NBME anatomy scores were significantly higher than those for all the lecture-based preclinical courses. Since the introduction of TBL in anatomy, student performance has progressively improved in the NBME subject examination. Students perceived TBL as a motivator to be a responsible team member and to contribute to collective learning by the team. Further, it reinforced self-directed learning and fostered an appreciation for peer respect. Interestingly, these perceptions were uniform irrespective of student course performance.  相似文献

EditorialEvidence based library and information practice     

Grant MJ 《Health information and libraries journal》2011,28(2):91-92

Whilst many of us engage in supporting clinicians in identifying, appraising and using evidence, how many of us adopt the same approach to our own work? A recent survey by the UK LIS Research Coalition indicated that 60% of respondents use research reports as a source of information whilst a similar proportion of health library respondents use professional events such as conferences as a source of information. This summer sees the 6^th International Evidence Based Library and Information Practice (EBLIP6) being held at the University of Salford, UK between 27^th‐30^th June which will go some way to satisfying this latter information need whilst the Health Information and Libraries Journal can help satisfy the need for research reports. Whatever you’re doing this summer, let’s make it evidence based.  相似文献   

Bridging the ‘Know‐Do Gap’: a role for health information professionals?     

Booth A 《Health information and libraries journal》2011,28(4):331-334

This feature briefly examines the development of knowledge translation, knowledge transfer and the knowledge broker role as constituting the next manifestation of the movement that brought us evidence based medicine and its derivatives. It examines the extent to which health information professionals currently meet the specification for a knowledge broker role. In doing so it assesses the strengths and weaknesses of the profession when ranged alongside the five components of the knowledge transfer process that is, problem identification; knowledge development and selection; analysis of context; knowledge transfer interventions; and knowledge utilization. Current deficiencies also lie in a need for political astuteness and awareness and in a lack of knowledge of the most significant models of behavioural change. The feature concludes by examining the potential for knowledge team approaches arguing that gains from a wider perspective that encompasses the entire knowledge process may be even more significant than the pooling of collective knowledge, skills and expertise.  相似文献
