Students often use incoherent strategies in their problem solving involving force and motion, as revealed, e.g. when they are asked to draw force diagrams for amusement rides involving circular motion, whether in horizontal or vertical planes. Depending on the questions asked, assignments involving circular motion can reveal different types of…

Smartphone-based experimental exercises were incorporated as part of the homework problems in an introductory mechanics course at a university. A quasi-experimental field study with two cohorts design was performed to measure the impact of such exercises on motivation, interest and conceptual understanding. The empirical results on learning…

Described is the interview-about-instances method used to gain insight into children's and adults' views of the world and the meanings people have for the words they use in explaining their views. Physics teachers can utilize this technique to become aware of the various concept understandings pupils bring to physics classrooms. (DS)

Focuses on the quantum atomic model Electronium. Outlines the Bremen teaching approach in which this model is used, and analyzes the learning of two students as they progress through the teaching unit. (Author/MM)

Outlines an alternative atomic model to the probability model, the descriptive quantum atomic model Electronium. Discusses the way in which it is intended to support students in learning quantum-mechanical concepts. (Author/MM)

Does a sensori-motor experience help a physics student understand the movement of molecules in solids, liquids, and gases? Students aged 9-10 were given either traditional demonstrations of solids, liquids, and gases and the variation of molecular motion with temperature (iconic presentation), or they were involved in physical activities as they…

Describes an approach to assessing the use of rules in solving problems related to Newton's third law of motion. Discusses the problems used, method of questioning, scoring of problem sets, and a general overview of the use of the technique in aiding the teacher in dealing with student's conceptual levels. (JM)

Suggests that the process view of science is flawed. Argues that (1) it is superficial and misleading to portray the method of science in process terms; (2) many of the processes have no special association with science; and (3) there is no evidence that performance is improved. Speaks of the challenge facing science education. (RT)

Critiques five arguments cited in support of process science. Considers the problematic nature of the processes and consequent difficulties encountered in mirroring these processes. Suggests an alternative way of viewing physics education through a trio of types of knowledge which can be used as governing principles in shaping education. (RT)

Discusses the process of increasing academic standards of students and broadening their knowledge in a balanced science education program. Describes assessment levels of knowledge with understanding and the basis for choosing course content material. Cites problems arising from management of project. (RT)
