Teachers’ episodic memories influence their beliefs. The investigation of episodic memories can help identify the teacher beliefs that limit technology-integration. We propose the Episode-Centered Belief Change (ECBC) model that utilizes teachers’ episodic memories for changing beliefs impeding effective technology integration. We also propose guidelines for using ECBC model in professional development to promote teacher belief change for effective technology integration. A preliminary study was conducted to apply the ECBC model in a teacher education course. The findings suggest that the ECBC model was effective in changing teacher beliefs regarding technology integration. Finally, the implications of the ECBC model and guidelines for research and practice are discussed. 相似文献

College readiness of students and the effectiveness of remedial mathematics courses have been under consideration for the last two decades. There is a considerable misalignment between the expectations of students regarding secondary education and those regarding higher education. Information about current expectations and perspectives of college mathematics faculty who have to deal with this gap is missing in the literature. This study explores college readiness of first-year students and topics that they need to have mastered before entering college. A survey was disseminated to college/university mathematics faculty throughout the US (48 states) whose email addresses were shown on their institutional webpages, and data were gathered from 737 faculty. The survey instrument includes scaled items reflecting the Common Core State Standards and free response items. The scaled items are divided into six subscales: Basics, Algebra, Functions, Geometry, Statistics and Probability, and Reasoning and Generalisation. Faculty responses are categorised and statistically analysed with respect to types of institution, position titles of the participants and types of course offered by those institutions. Findings indicate that faculty view first-year students as having poor mathematical ability in terms of what they consider to be important topics for college preparation. Faculty also agree that students need remediation, which, in its current state, is not sufficient. Implications of these results for further research and practice are discussed. 相似文献

In this paper, we propose a novel optimal quality adaptation algorithm for MPEG-4 fine granular scalability (FGS) stream over wired network. Our algorithm can maximize perceptual video quality by minimizing video quality variation and increasing available bandwidth usage rate. Under the condition that the whole bandwidth evolution is known, we design an optimal algorithm to select layer. When the knowledge of future bandwidth is not available, we also develop an online algorithm based on the optimal algorithm. Simulation showed that both optimal algorithm and online algorithm can offer smoothed video quality evolution. 相似文献
