Marie Ståhl and Anita Hussénius have defined what discourses dominate national tests in chemistry for Grade 9 in Sweden by using feminist, critical didactic perspectives. This response seeks to expand the results in Ståhl and Hussénius's article "Chemistry inside an epistemological community box!--Discursive exclusions and inclusions in the…

This study involved the evaluation of the efficacy of a planned instructional program to facilitate understanding of the macroscopic, submicroscopic and symbolic representational systems when describing and explaining chemical reactions by sixty-five Grade 9 students in a Singapore secondary school. A two-tier multiple-choice diagnostic instrument…

This paper reports on an investigation of the effectiveness an intervention using several different methods for teaching solution chemistry. The teaching strategy comprised a four-step approach derived from a constructivist view of learning. A sample consisting of 44 students (18 boys and 26 girls) was selected purposively from two different Grade…

The present study focused on investigating the effectiveness of instruction via newly developed teaching materials based on cooperative learning when compared to a traditional approach, on ninth grade students' understanding of metallic bonding. Fifty-seven ninth grade science students from two science classes in the same high school participated…

This report is an evaluation of an attributional retraining intervention conceptualized to promote girls gifted in the natural sciences. The attributional retraining was based on a modeling technique, and conceptualized for ninth-grade chemistry students attending a college preparatory high school (German Gymnasium). The aim of the training was to…

The aims of this study were considered under three headings. The first was to elicit misconceptions that students had about the terms "solute", "solvent" and "solution." The second was to understand how students' prior learning affected their misconceptions. The third was to determine if students were able to make a…

The project was to design, produce, and field test interactive video materials to increase junior high school student interest in physics and chemistry. A curriculum development team consisting of junior high school physical science students and teachers and university educators produced a seven-part videotape series entitled "The…

The Second International IEA Science Study (SISS) had participants from 24 countries. In this report the data collected in 17 countries are analyzed and reported. Students from the 5th, 9th, and 12th grades were tested. The results from achievement tests, student questionnaires, opinionnaires, a science teaching and learning inventory, a word…
