Several researches in physics education have demonstrated the problematic status of teaching the subject of gravitation and weight and students' knowledge of these concepts. This paper presents findings of a study of students' knowledge following instruction within a changed conceptual framework of the weight concept in several 9th grade classes…

Investigates the performance, gender differences, interrelationships among five tasks, relationship with paper and pencil tests, relationships with background variables, and contribution of schools from the Israel data of the Second International Science Study (SISS). Compares the Israeli results with those of Japan. (YP)

A remedial instructional strategy (developed and implemented in ninth-grade physics classes) was found to significantly affect low/mixed ability students' achievement. The method was developed on the basis of a needs assessment of students' backgrounds and a detailed task analysis of the physics course's cognitive demands. (JN)

Data from the 1983-84 Israeli IEA (International Association for the Evaluation of Education Achievement) science study were used to explore gender-related differences (and their determinants) in the learning of science. The study (n=1974) involved several measures of science learning, 10 attitudinal measures, and items and errors classification.…

Information on the content of the intended science curriculum, what science was actually taught by the teachers, and how that science was taught is presented. Student achievement and attitudes were assessed using tests and questionnaires. Data were obtained from teachers regarding whether the content had been taught to the students (n=657) who…
