In this study, the effect of conceptual-change-texts-oriented instruction to seventh-grade students' understanding of ecological concepts was investigated. Using information collected through interviews and related literature, the Ecology Concept Test was developed and administered to 58 elementary students in two classes of an elementary school…

The conceptions of chemistry teachers with diverse backgrounds within a large urban district are assessed. The Chemistry Concepts Inventory (CCI) and Mulford and Robinson's research study were utilized for reference and conceptual factors contributing to teachers' conceptions such as degree major and credential status were analyzed from data…

Several Canadian universities and colleges have been working together for years to build Web-accessible computer-based applets to help students learn physics concepts. This paper reports the findings from a study that evaluated the effectiveness of these applets in enhancing conceptual learning. We integrated quantitative and qualitative methods…

This paper reports on a paper and pencil concept-sorting strategy that enables trainee teachers to restructure their knowledge in any one domain of science. It is used as a self-study tool, mainly to enable them to break down and understand the progression of concepts beyond the level at which they have to teach. The strategy involves listing key…

This study examined 10th-grade students' use of theory and evidence in evaluating a socio-scientific issue: the use of underground water, after students had received a Science, Technology and Society-oriented instruction. Forty-five male and 45 female students from two intact, single-sex, classes participated in this study. A flow-map method was…

In one Australian state, a concerted effort has been made to impact the literacy achievement of students during the early years of schooling, especially those students attending primary schools in identified least-advantaged areas. While these initiatives have been successful, their impact has been enhanced by the development of print-enriched…

"The pleasure of finding things out" is a collection of short works by the Nobel Prize winning scientist Richard Feynman. The book provides insights into his infectious enthusiasm for science and his love of sharing ideas about the subject with anyone who wanted to listen. Feynman has been widely acknowledged as one of the greatest physicists of…

An important aim of primary science programmes should be to continue to encourage and nurture children in creating their own explanations. As Osborne and Freyberg (1985) contended, the aims of primary science in the early years should start with the children developing explanations for their experiences. The first two of their six developing aims…

The purpose of this paper is to describe an instructional sequence where students invent a method for locating lines of eigenvectors and corresponding solutions to systems of two first order linear ordinary differential equations with constant coefficients. The significance of this paper is two-fold. First, it represents an innovative alternative…

This article focuses on the kinds of conceptual changes that occur when students have to deal with negative numbers in elementary algebraic operations. Interviews were carried out with twelve 8th-grade level students who were selected on the basis of their results in a test where they were required to reduce polynomials. The questions applied to…

This article profiles a group of college students with learning disabilities, outlines strategies used to help those students in their 100-level expository-writing class, and illustrates persistent writing problems with three student writing samples. This study revealed that, even with explicit support, students whose learning disabilities had an…

Findings are presented from a small-scale longitudinal study of first-year psychology students' learning. Three developmental hierarchies were derived in the analysis of the interview data, which described different aspects of the variation in students' accounts of their conceptions of essay writing. Although the findings did suggest that the…

The growth in science understanding and reasoning of 12 children is being traced through their primary school years. The paper reports findings concerning children's growing understandings of evaporation, and their changing responses to exploration activities, that show the complexity and coherence of learning pathways. Children's responses to…

In this investigation, we examined children's knowledge of cosmology in relation to the shape of the earth and the day-night cycle. Using explicit questioning involving a choice of alternative answers and 3D models, we carried out a comparison of children aged 4-9 years living in Australia and England. Though Australia and England have a close…

Objective: To investigate the effect of a nutrition education intervention and four hours of related teaching on the nutrition concepts of a sample of 9 year-old children. Design: Prepost test design. Children's food classification concepts were assessed before and after the intervention and nutrition teaching. Setting: Year 4 class of a suburban…
