The primary purpose was to investigate the efficacy of a full year of single-sex (SS) teaching of science. The secondary aims were to locate any differentiation by set and gender, and to relate these to more proximal variables. Participants were 13 year olds. Higher set girls gave evidence of clear benefits overall, and higher set boys also,…

This paper examines what is important about talk between learners during school science and, having identified this, suggests how we can ensure that what we consider important happens. By looking at the interaction between teachers and learners talking about science, it is possible to indicate ways in which learners can be helped to continue this…

This study explores college students' representations about the nature of theories during their enrollment in a large astronomy course with instruction designed to address a number of nature of science issues. We focus our investigation on how nine students represent their understanding of theory, how they distinguish between scientific theories…

The aim of this study was to detect primary students' conceptions about the origin and conveyance of electric current and about the connection of household electric appliances. In total, 383 students (aged 11-12) from the town of Volos, Greece, participated; 213 of them drawn from experimental classes and 170 from control groups. The results…

Just how open-minded are modern scientists? In this paper we examine this question for the science faculty from New Zealand and UK universities. The Exeter questionnaire used by Preece and Baxter (2000) to examine superstitious beliefs of high school students and preservice science teachers was used as a basis for a series of in-depth interviews…

This paper addresses the concept of geological time as used by students who face tasks that demand three types of skills: to locate events in time, to order them according to time calendar, and to manage time intervals. The empirical study consisted of asking high school students as well as technical school students to carry out tasks that…

This paper is concerned with issues affecting equity in science education for girls and boys. In the paper the results of an investigation into the recently published (1998-2000) series of textbooks entitled Lower Secondary Science for Brunei Darussalam are presented. In the first part of the paper, background issues of continuing gender…

In an investigation of the learning of science content knowledge in a postgraduate preservice education course, it was found that the 'failure of further learning' effect can be overcome, at least in part, in well-designed courses. Nevertheless the persistence of certain misconceptions among some students did indicate the partial salience of the…

Studies exploring school students' views about science have not always distinguished between different branches of science. Here, the views of 1395 secondary school students aged 11-16 about physics and, as a science comparator, biology were determined using a closed-form questionnaire. Over the period of secondary schooling a decreasing…

Design activities allow students to create their own solutions, drawing upon a personal understanding of science principles and examples. We created the 'Houses in the Desert' project to engage middle school students in designing a passive solar house that will keep its owners comfortable in the desert climate. Students used their knowledge of…

The construct of "situational interest" involves the identification of classroom factors that arouse student interest, but previous research has focussed on non-science domains such as reading or mathematics. The first aim of this study was to identify the sources of situational interest in a science content/methods course for primary teacher…

In this study we investigated the design of assignments by students as a knowledge-generating activity. Students were required to design assignments for 'other students' in a computer simulation environment about electrical circuits. Assignments consisted of a question, alternatives, and feedback on those alternatives. In this way, subjects were…

This paper looks at three case studies within the teaching and learning of chemistry. Each case considers the effectiveness of group learning activities in terms of the ways in which they enhance cooperative learning. Group tasks are generally undertaken in order to encourage learners to develop their understanding of particular issues, lthough…

The problem addressed in the study was whether 10-year-old and 11-year-old children, collaborating within a computer-supported classroom, learned an explanation-driven process of inquiry that had characteristics of the progressive nature of scientific inquiry. The technical infrastructure for the study was provided by the Computer-Supported…

In this study, we juxtapose the purpose and procedures for school science inquiry activities as they are portrayed in curriculum policy statements, provincial assessment materials and teacher resources with a teacher's enactment of these policy and resource directives in her classroom. This article draws on data collected during a Grade 6…
