Challenging Topics in Science 1 Helping students understand challenging topics in science through ontology training
Chi (2005) has proposed that students experience difficulty in learning about physics concepts such as light, heat, or electric current because they attribute these concepts with an inappropriate ontological status of material substances rather than the more veridical status of emergent processes. Conceptual change could thus be facilitated by training students in the appropriate ontology prior...
متن کاملOptimizing Computer-assisted Pronunciation Instruction by Selecting Relevant Training Topics
We introduce a novel method to diagnose pronunciation errors that are most critical to the intelligibility of L2 learners. A prelimiary study showed that error rates computed by a speech recognition-based system can be used to characterize intelligibility. We deduce a probabilistic algorithm to derive intelligibility from error rates. We also define an error priority function that indicates whi...

متن کاملTopics in Representation Theory: Other Topics
• Topology of G/T : Flag manifolds G/T have cohomology only in even degrees, with Euler characteristic the degree of the Weyl group. The Euler characteristic can be calculated by a Lefschetz fixed point argument (see Adams [1], pgs. 90-92 for this). Identifying the flag manifold with a co-adjoint orbit, there is a Morse theory calulation of the cohomology that goes back to Bott, for an outline ...
متن کاملCURRENT TOPICS Effects of Physical Training on Myocardial Vascularity and Perfusion
Physical training is thought to be a stimulus for coronary vascular growth and coronary collateral development. This report is a summary of knowledge in the area. Studies in experimental animals with normal hearts indicate that physical training promotes increased myocardial capillary density and also causes enlargement of the surface coronary vessels. The physiologic effect of these changes on...
