In this paper, we present a case study of a beginning chemistry teacher who enrolled in a project aimed to contribute to the development of teachers' knowledge of models and modelling in science. The project consisted of a series of institutional meetings in combination with an action research project the teacher conducted in her own classes. By…

The purpose of this article is to describe the development, validation and use of the "Constructivist Multimedia Learning Environment Survey" (CMLES). This questionnaire assesses teachers' and students' perceptions of the learning environment when students use online multimedia programs while teachers use constructivism as a referent for their…

The purpose of this study was to describe how three primary teachers attempted to overcome incomplete content knowledge when teaching an astronomy unit. Daily observations of science activities were videotaped and transcribed from each classroom to determine the influences on the changes in teacher and student ideas of astronomy. Teachers' ideas…

The new 1?9 curriculum framework in Taiwan provides a remarkable change from previous frameworks in terms of the coverage of content and the powers of teachers.

In this paper I examine the phenomenon of university teachers as researchers in their own classrooms. I use examples of three research teams in which we studied: (1) student response to a science and society course; (2) teacher and student perceptions of inquiry in a physics course; and (3) teaching and learning about the nature of science in an…

We report on a study of what happened when we recycled a conceptual examination question in a first-year university physics course. The question, which was used for three consecutive years, asked about an astronaut's experience of weighing in an orbiting space-craft. The original intention was to use a phenomenographic approach to look for…

During their years of schooling, students develop perceptions about learning and teaching, including the ways in which teachers impact on their learning experiences. This paper presents student perceptions of teacher pedagogy as interpreted from a study focusing on students' experience of Year 7 science. A single science class of 11 to 12 year old…

The explanations of thirty primary pupils for changes in matter were recorded through individual, semi-structured interviews. The analysis of data pointed to the construction of a system for classifying pupils' explanations of changes in matter. A parallel analysis of data focused on the identification and interpretation of associations between…
