For most students textbooks are the main source of their information about scientific concepts; however, there are a number of errors which frequently appear in textbooks and are consequently transmitted to both teachers and students. Some of these errors which may represent widespread misconceptions of teachers are outlined. (Author)

Discusses the use of logarithm and reciprocal graphs in the college physics classroom. Provides examples, such as electrical conductivity, reliability function in the Weibull model, and the Clausius-Clapeyron equation for latent heat of vaporation. Shows graphs with weighting of points. (YP)

Presents examples of evaluation studies of visitor interactions with science museum exhibits. Example one involves application of existing findings about naive notions of motion to task of engineering a novel encounter with parabolic trajectories. Example two is a student project evaluating a prototype exhibit on light pipes and concludes that…

A general model of conceptual change which is largely derived from current philosophy of science, but which can illuminate learning as well, is described. Some features of this model are illustrated by interviews with students studying special relativity in physics. Finally, some pedagogical implications are presented. (Author/PB)
