This paper is an invited adaptation of the IEEE Education Society Distinguished Lecture Approaches to Interactive Video Anchors in Problem-Based Science Learning. Interactive video anchors have a cognitive theory base, and they help to enlarge the context of learning with information-rich real-world situations. Carefully selected movie clips and…

Kumar, David Devraj; Thomas, P. V.; Morris, John D.; Tobias, Karen M.; Baker, Mary; Jermanovich, Trudy – Journal of Science Education and Technology, 2011
This study examined the impact of computer simulation and supported science learning on a teacher's understanding and conceptual knowledge of current electricity. Pre/Post tests were used to measure the teachers' concept attainment. Overall, there was a significant and large knowledge difference effect from Pre to Post test. Two interesting…

Kumar, David Devraj; Sherwood, Robert D. – Journal of Science Education and Technology, 2007
A study of the effect of science teaching with a multimedia simulation on water quality, the "River of Life," on the science conceptual understanding of students (N = 83) in an undergraduate science education (K-9) course is reported. Teaching reality-based meaningful science is strongly recommended by the National Science Education Standards…
