This article reports on findings from a two-year project--'Improving Science Together'--undertaken in 20 primary and four secondary schools in and around Bristol, UK. The project was funded by the pharmaceutical company AstraZeneca PLC as part of their national Science Teaching Trust initiative, and had as one of its aims the development of…

A models and modelling approach was adopted to investigate the educational potential of a science museum exhibition. It focused on patterns of relationship between the teaching models proposed by designers and students models in regard to four exhibits concerning astronomical cycles. Student's models were elicited by interviewing 21 pupils…

The objective of this study was to investigate the effect of a socio-cognitive teaching strategy on young children. It tests their understanding of the factors that friction depends on when an object is projected across a horizontal surface. The study was conducted in three phases: pre-test, teaching intervention, and post-test. The sample…

This study is an investigation of the impact of collaborative teaching by student-teachers and classroom teachers on children's enjoyment and learning of science. The paper describes findings from a project in which undergraduate science specialist student-teachers were placed in primary schools where they 'co-taught' investigative science and…

The search for authentic science research tools to evaluate student understanding in a hybrid learning environment with a large multimedia component has resulted in the use of concept maps as a representation of student's knowledge organization. One hundred and seventy third-semester introductory university-level engineering students represented…

In this study, we investigated the perceived professional needs of Korean science teachers majoring in chemical education, and examined their preferences for online and on-site inservice teacher training programmes. The results were also compared with those of preservice teachers. Participants were 120 secondary school teachers and 67 preservice…

The paper reports findings from research into the extent to which an on-line course, "Try Science", achieved its objectives compared with a face-to-face course with the same content and objectives. "Try Science" has the dual aims of developing participants' understanding of science content and of teaching science through enquiry. Whilst the…

We compare the content that was expected with what actually was put into practice in a course of ongoing education of secondary education (12-16 year olds) science teachers, and describe the most relevant problems that arose. We believe that the educational content--its nature, how it is organized and presented to the teacher participants, and so…

This paper reports design experiments on two Japanese elementary science lesson units in a sixth-grade classroom supported by computer support for collaborative learning (CSCL) technology as a collaborative reflection tool. We took different approaches in the experiments depending on their instructional goals. In the unit 'air and how things…

This article reports the use of a computer-based collaborative learning instruction designed to help students develop understanding of image formation by lenses. The study aims to investigate how students, working in dyads and mediated by multimedia computer-assisted learning (CAL) programs, construct shared knowledge and understanding. The…

The increased availability of computational modeling software has created opportunities for students to engage in scientific inquiry through constructing computer-based models of scientific phenomena. However, despite the growing trend of integrating technology into science curricula, educators need to understand what aspects of these technologies…

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…

Accepting that scientific literacy is the primary purpose of science in the compulsory years of schooling leads to the question 'What does scientific literacy mean in a particular community?' This paper reports a study designed to provide some insight into that question. Data were gathered through interviews with a sample of community leaders, in…

This study investigated prospective secondary science teachers' understandings of and intentions to teach about scientific modelling in the context of a model-based instructional module. Qualitative methods were used to explore the influence of instruction using dynamic computer modelling. Participants included 14 secondary science prospective…

The purpose of this paper is to carefully examine the evolution of students' theory building and modeling, critical components of scientific epistemologies, over a unit of study on sinking and floating in one third/fourth grade classroom. The study described in this paper follows in the tradition of Design Experiments (Brown 1992, Collins 1990)…
