This paper is a survey of context-based chemistry education in the United States. It begins with a very brief overview of twentieth-century chemistry texts and teaching methods, followed by a short description of a pioneering secondary school text. The major emphasis is on post-secondary instruction and the central case study is provided by…

In this paper, we present the development and implementation over the period of more than 15 years of learning materials focusing on industrial chemistry as the main theme. The work was conducted in the Department of Science Teaching at the Weizmann Institute of Science, Israel. The project's general goal was to teach chemistry concepts in the…

Some of the most pressing problems currently facing chemical education throughout the world are rehearsed. It is suggested that if the notion of "context" is to be used as the basis for an address to these problems, it must enable a number of challenges to be met. Four generic models of "context" are identified that are currently used or that may…

In this paper we reflect on the experiences and results of the development and implementation of context-based chemistry education. This development is discussed with respect to five challenges defined for chemistry curricula (Gilbert, 2006). Five context-based approaches were selected that will provide the data for this study (Bennett & Lubben,…

"Chemie im Kontext" (ChiK) is a project that aims at the improvement of chemistry teaching at secondary school in Germany. Based on a framework that was derived from theories and empirical data on the teaching and learning of science, science education researchers and teachers work together on learning communities to transform this framework into…

This paper synthesizes findings from three studies to answer a general question: What do casual, adult visitors learn about science from their science-related experiences in free-choice settings? Specifically we asked whether there are changes in how people think about science in their daily lives, the nature and use of scientific knowledge, and…

In this study, the responses of teachers and their pupils to the educational programme "Nature on the Way to School" were investigated with the help of questionnaires. The main objectives of the programme were the promotion of opportunities for children to experience nature first-hand on the way to school, the promotion of children's awareness of…

Although many research studies report students' Lamarckian misconceptions, only a few studies present learning and teaching strategies that focus on the successful development of the concept of natural selection. The learning and teaching strategy for upper secondary students (aged 15-16) presented in this study conducted in The Netherlands is…

In recent years, increasing emphasis has come to be placed, both by researchers and by policy-makers, on the adequacy of primary teachers' subject knowledge of science. Within research, this emphasis has been linked to the rise of constructivist ideas about the significance of establishing children's prior conceptions of scientific concepts for…

This paper reports the relationship between four English primary teachers' understanding of the nature of science and their practice. Action research was included as a major part of the research design in order to explore the dialectical interplay between various factors at work in the teachers' practice. The influences of both tacit and espoused…

This study explored teachers' pedagogical strategies for using multimedia simulation to structure and support secondary science teaching. Expertise was investigated across a range of classroom settings to analyse how specialist knowledge is situated within and adapted to the teaching and learning context. Analysis of data arising from 10 lesson…

Few studies have dealt with students' preconceptions of sounds. The current research employs Reiner "et al." (2000) substance schema to reveal new insights about students' difficulties in understanding this fundamental topic. It aims not only to detect whether the substance schema is present in middle school students' thinking, but also examines…

Cognitive Acceleration through Science Education (CASE) is an intervention programme conducted during Years 7 and 8 in the United Kingdom (aged 11-13 years), which has reported remarkable success in enhancing cognitive development and in raising academic achievement. Critics, however, have questioned whether a purely cognitive mechanism can…

The article presents some of the results of the questionnaire-based Relevance of Science Education Project carried out in England in the latter half of 2003 as part of a wider international comparative study based at the University of Oslo. Data, drawn from 1,277 students, most of them 14 or 15 years old, indicate their attitudes towards a series…

The development of a science education that includes a focus upon the nature of science suggests the need for "pedagogic tools" that can be used to engage children with the procedural understandings that are central to the scientific approach to enquiry. This paper reports on a collaborative action research project that focused on the use of…
