Interviews university students in modern physics about their understanding of three fundamental experiments. Explores their development of models of microscopic processes. Uses interactive demonstrations to probe student understanding of modern physics experiments in two high school physics classes. Analyzes the nature of students' models and the…

The educational potential of agriculture stems from the diversity and tangibility of its components. As a science based human activity, it may provide the educator with a unique combination of educational opportunities in a context which is authentic and accessible to the pupil and to the teacher.

Describes an investigation of the strategies used by 47 high school students in solving volumetric analysis problems in chemistry. Reports that students in the high ability group mainly used the "formula" approach, while those in the low ability group tended to use the "proportional" approach to problem solving. (TW)

The focus on practical investigations in the National Curriculum is seen to be important if students are to attain a connoisseurship in science experimentation. The chain of processes involved in doing real science involves: non-linear thinking; creative flair; and critical evaluation within an authentic setting. The research presented in this…

Describes the use of analogy relative to the classical theory of momentum and kinetic energy, and addresses the advantages and disadvantages of this approach with respect to modern physics. Discusses the origins of the billiard ball analogy in the work of Coriolis and its influence on later theories and investigations of nuclear fission, particle…
