Presents notes on the objectives of laboratory instruction, the design of assessment systems on the principles of criterion-referenced measurement, student ability to measure, and student attitudes toward the importance of physics. (GS)

Presents seven selected biology notes which could be used in the school biology courses. Each includes the name of the author and a description of activities suggested. (HM)

Presents a numerical simulation of a simple food chain together with a set of mathematical rules generalizing the model to a food web of any complexity. Discusses some of the model's interesting features and its use by students. (Author/JRH)

Reports on Project 2 from the Evidence-based Practice in Science Education (EPSE) Research Network. In this project, teachers and researchers worked collaboratively on the design of three short teaching sequences on electric circuits. (DDR)

Reports on a study by the Evidence-based Practice in Science Education (EPSE) Research Network that explores practitioners' views on the nature, use, and potential of science education research. (DDR)

Summarizes the results of a meeting of activists from the field of instructional technology who consider the likely impact instructional technology will make on the future science curriculum. Contains 17 references. (DDR)

Describes an attempt to introduce differentiation by task in an inner city secondary school. Concludes that differentiated work cards lead to no significant improvement in the achievement of lower ability students. High and medium ability students improved their performance as a result of using the work cards. (DDR)
