This quantitative study investigated the relationship between teacher dispositions, subject content knowledge, pedagogical content knowledge, and reasons that school principals recommend non-renewal of probationary teachers' contracts. Principals in the Southeastern Unites States completed an e-mailed survey. Two nonparametric tests, Kruskal-Wallis and Mann Whitney U, were used to statistically analyze group responses. Principals reported that they observed most a lack of pedagogical content knowledge from ineffective teachers and they prioritized the importance of instructional skills in deciding whether to non-renew a teacher contract. Principals identified teacher integrity, dependability, and honesty as important dispositions. The studies' findings are important for universities that prepare preservice teachers and also for the planning of professional development initiatives. The study findings suggest that principals tend to view dispositions as personality characteristics rather than as teacher competencies and that teacher expertise in both subject content and pedagogy must be woven together. 相似文献
Background: In recent years increasing attention has been given to models-based approaches to physical education as a way of promoting standards and particular types of learning through better alignment of teacher planning and delivery with pupil learning and achievement. However, little attention has been given to the specific contribution a pedagogical model for outdoor adventure education (OAE) has to make to pupils learning.
Purpose: This paper is presented in two parts. Part one is an advocacy paper and draws upon the broader discourse around models-based practice to make a case for the development of a pedagogical model for OAE. Drawing upon guidelines for models-based approaches to physical education, this paper considers the theoretical foundation, rationale, review of research findings and major theme that inform the development of a model of OAE.
Conclusions: The selected review of the research suggests that the major impact of OAE is upon the affective domain, particularly in relation to pupils developing a positive self-concept. Learning is also evident in the cognitive and physical domains, but this is secondary to learning in the affective domain. Drawing upon the analysis of the research literature, the major theme for the model is identified as ‘personal growth through adventure’ and ‘OAE’ is suggested as the name of the model. Part two of this paper builds upon these foundations to outline what a pedagogical model for OAE might look like in a secondary school in the UK. 相似文献
Big data, like MOOCs, altmetrics and open access, is a term that has been commonplace in the library community for some time yet, despite its prevalence, many in the library and information sector remain unsure of the relationship between big data and their roles. This editorial explores what big data could mean for the day‐to‐day practice of health library and information workers, presenting examples of big data in action, considering the ethics of accessing big data sets and the potential for new roles for library and information workers. 相似文献
We contrast the current science education reform effort with the reforms of the 1960s and suggest how the current effort could be enhanced. We identify insights from recent research that we believe can inform the reform process, in particular, to reach all science students and also impart a cohesive view of science. We propose an alternative models view of scientific explanation and show how this view would contribute to reforms of (1) course goals, (2) social aspects of science learning, (3) instructional practices, and (4) roles for technology.This paper summarizes discussions and debates that the authors have had over the last few years. The dialogue stems, in part, from our joint participation in the American Educational Research Association Special Interest Group on Education in Science and Technology (AERA SIG:EST) leadership. This paper communicates the spirit of our thinking and does not necessarily reflect the view of SIG:EST, or any other organization.We gratefully acknowledge the support of National Science Foundation Grant MDR-9253462 in work related to this paper.

The interrelationship among language components is the main conceptual framework for this study which examined the written language performance of Jamaican children with severe to profound hearing loss. Twelve subjects aged 15 to 16 years completed text level tasks in writing, reading and sign language. Hearing children aged 13 to 14 years completed writing and reading tasks. Multilevel analyses were undertaken. Differences and parity in performances were observed within and between groups at the word, sentence and text levels. Deaf children's ability to express complex ideas in sign language in the Jamaican education system indicated a need for nontraditional approaches in the teaching of written language. Suggestions are outlined for developing an instructional model to enhance written language using a bilingual approach. 相似文献
In each of two experiments, rats were trained to press the lever in a Skinner box, food reinforcement being available on a variable-interval 60-sec schedule (VI 60). There followed an “exposure phase” for which the levers were removed from the boxes, and then a final test with the levers replaced to assess the effects of the intervening treatment on instrumental responding. Experiment 1 showed that simple exposure to the box reduced the vigor of instrumental performance in comparison with a condition in which food was made available during the exposure phase. Animals which received no exposure treatment also showed a relatively high rate of response. Experiment 2 demonstrated that an exposure treatment in which the occurrence of food is signaled by a light stimulus also leads to a decline in instrumental responding. These results are held to support the notion that associations between the context and the reinforcer serve to energize appetitive instrumental behavior. 相似文献
