Recent research on principles of best practice for designing effective multimedia instruction has rarely taken into account students’ alternative conceptions, which are known to strongly influence learning. The goal of this study was to determine how well students of quantum mechanics could learn ‘vicariously’ by watching a student-tutor dialogue based on alternative conceptions. Two video treatments were created to summarize key aspects of quantum tunneling, a fundamental quantum mechanical phenomenon. One video depicted a student-tutor dialogue, incorporating many of the common alternative conceptions on the topic, and resolving inconsistencies in reasoning through discussion. The other presented the same correct physics material in an expository style without alternative conceptions. Second year physics students were randomly assigned to one of the two treatments and were tested before and after watching the video during a lecture. Results show a statistically significant (p < .01) advantage for the learners in the dialogue treatment (d = 0.71). Follow-up interviews of students yielded insight into the affective and cognitive benefits of the dialogue video.  相似文献

One of the bedrock of Sustainable Development Goals (SDGs) is eradication of poverty and hunger. In an attempt to actualize this goal, the role of public libraries in information provision to agricultural extension agents in Nigeria becomes paramount. This paper discusses provision of information to agricultural extension agents in a developing country. It starts with the concept of extension agents and the essence of information provision to them. It further discusses types, sources and challenges of public libraries in information provision to agricultural extension workers in a developing country. Some of the challenges are as follows: poor funding of public libraries, demotivated staff, and so on. Based on these discussions, the paper recommended adequate training and retraining of staff, adequate funding of public libraries by the federal, state and local government, the revitalization of the abandoned mobile library services among others. The paper therefore concludes that information provision to agricultural extension agents by public library is very crucial for national development. The current state of poverty, hunger and lack in Nigeria and some other African countries could be reduced to a great extent if current, relevant and up-to-date information are provided by libraries to the concerned agencies.  相似文献

Interpersonal respect is a fundamental aspect of relating to others. This is especially true for teachers, as cultivating relationships is implicit in effective teaching. This three-year qualitative study examines a developing understanding of respect for pre-service teachers that progresses on to their first year’s teaching to examine the influential factors on that understanding. These teachers’ pupils were also asked to comment on their perceptions of respect. The findings indicate that interpersonal respect in an educative relationship is influenced by the level of autonomy afforded pupils and minimising the power differential between teachers and pupils.  相似文献

High-fidelity anatomical models can be produced with three-dimensional (3D) scanning techniques and as such be digitally preserved, archived, and subsequently rendered through various media. Here, a novel methodology—digital body preservation—is presented for combining and matching scan geometry with radiographic imaging. The technique encompasses joining layers of 3D surface scans in an anatomical correct spatial relationship. To do so, a computed tomography (CT) volume is used as template to join and merge different surface scan geometries by means of nonrigid registration into a single environment. In addition, the use and applicability of the generated 3D models in digital learning modalities is presented. Finally, as computational expense is usually the main bottleneck in extended 3D applications, the influence of mesh simplification in combination with texture mapping on the quality of 3D models was investigated. The physical fidelity of the simplified meshes was evaluated in relation to their resolution and with respect to key anatomical features. Large- and medium-scale features were well preserved despite extensive 3D mesh simplification. Subtle fine-scale features, particular in curved areas demonstrated the major limitation to extensive mesh size reduction. Depending on the local topography, workable mesh sizes ranging from 10% to 3% of the original size could be obtained, making them usable in various learning applications and environments.  相似文献

The paper is reviewing the tools to handle high-order sliding mode design and robustness. The main ingredient is homogeneity which can be checked using an algebraic test and which helps us in obtaining one of the most desired properties in sliding mode control that is finite-time stability. This paper stresses some recently obtained results about homogeneity for differential inclusions and robustness with respect to perturbations in the context of input-to-state stability. Lastly within this framework, most of the popular high-order sliding mode control schemas are analysed.  相似文献

The ‘theory-practice divide’ in teacher education can be viewed not simply as an acceptance of a body of knowledge but instead an acceptance of the teacher educator’s authority to determine what is relevant educational theory. This research aimed to explore student teachers’ views of ‘educational theory’ and how it was discursively positioned relative to their practice in an attempt to examine whether their acceptance or rejection of it was also related to accepting the authority of the teacher educator. Using one-to-one interviews with 23 student teachers and employing a discourse analysis, four categories of students emerged. The paper describes these four categories and discusses the implications of these findings for initial teacher education and our understanding of the ‘theory-practice’ gap.  相似文献
