Dynamics course − is themost useful model because it can be used even before a semester begins and thus the instructorhas sufficient time to consider what proactive measures s/he will use in the new semester.However, if an instructor wants to generate a large number of good predictions, so s/he can focuson individual students, particularly those “academically at risk” students, Model #1 should not beused because of its lowest percentage of good predictions. Either Model #2 or Model #3 can beused after the first or second mid-term exams because both models have moderate predictabilityto generate good predictions. For example, if Model #2 or Model #3 predicts that a student willreceive a final exam score below 50 (out of 100), the student will be

A university-wide survey was conducted to identify areasof instruction that needed improvement, and solicit suggestions on ways

However, much more time is required if one designs and builds custom apparatuses,such as a rig for 2 DOF torsional system developed by Souza et al. 3 Also, with a customapparatus, custom instrumentation and transducers are required – which may or may not beresearch caliber instruments.

‘depth-averaged’ model.However major subsequent contributions to the subject matter took place during the 1960’s,wherein ‘variable-depth’ models were introduced. Let us consider for example, the potential flow over a horizontal bed. Let us consider a three-dimensional space with co-ordinates, x, y, z. However, for this example let us consider only the two dimensional plane x and z. If h is the mean water depth, and z is the vertical coordinate, then z = – h. One can arrive at a Taylor Expansion of the velocity potential η∀(x,z,t) around the bed level, z = – h. Page 15.214.3 Assume that u is the

comprehensive review of this literature here, wecite and discuss selected works that have influenced our thinking.A large body of research evidence suggests that active learning techniques – broadlytaken here to mean any form of instruction that engages students beyond passivelyreceiving information – promote learning10,11. A particularly convincing study conductedby Hake in the 1990’s demonstrated that physics students exposed to some form of“interactive engagement” developed higher levels of conceptual understanding than thosein “traditional” instructional settings12. Active learning grounds the SCALE-UP projectat North Carolina State University13, many of the integrated engineering curricula thatemerged in the 1990’s14, and some of the emerging
