This paper tests the utility of a new sociocognitive frame for analysing the development of teachers' knowledge--the knowledge integration perspective (Linn, Eylon, & Davis, in press; Linn & Hsi, 2000). In doing so, the paper describes one prospective elementary teacher's developing knowledge and highlights its complexity. The prospective teacher…

Science teaching environments are social environments, and teachers' emotions interact with their science teaching in powerful ways. To value the teacher is to value the whole person, not just the intellect. In this paper, a theorization of teacher emotion in science teaching is developed which illustrates the role of emotion in establishing and…

Agriculture, industry and medicine are being altered by new biotechnologies. Biotechnology education is important because today's students and citizens will make decisions about the development and application of these new molecular biologies. This article reports an investigation of the teaching of biotechnology in an Australian state, New South…

We report on two studies in which high school students who had been exposed to a cognitive training procedure known as the Conceptual Mediation Program (CMP) were compared to students who had not participated within the program. In the first study, based on data from two sites, it was found that 70 CMP students exhibited higher levels of school…

This case study describes an instructional approach that may be useful in inquiry-based science classes. It involves adopting a particular discourse orientation that aims at helping pupils value their science learning. The contextual descriptions and interpretation presented can help teachers form images of classroom practices that will be…

This paper focuses on the use of multimedia-based predict--observe--explain (POE) tasks to facilitate small group learning conversations. Although the tasks were given to pairs of students as a diagnostic tool to elicit their pre-instructional physics conceptions, they also provided a peer learning opportunity for students. The study adopted a…

This study reports on teaching practices in science classrooms of Indonesian lower secondary schools in rural areas. Using six schools from three districts in the province of Kalimantan Selatan as the sample, this study found that most teaching practices in science classrooms in rural schools were teacher-centred with students copying notes.…

This paper is about a study into the nature of analogies recorded from three Form 2 (Grade 10) classes in Kenya, instructed by three physics teachers. Through a case study method involving classroom observation, several analogies were recorded and analysed. These analogies were predominantly "environmental" (drawn from students' socio-cultural…

This study examines the nature and process of ninth grade students' conceptual change regarding their mental model of dissolution and diffusion as a result of instructions using the Dual Situated Learning Model (DSLM). The dual situated learning events of this model are designed according to the students' ontological viewpoint of the science…

The purpose of this investigation was to apply a validated curriculum evaluation instrument, the "Science Curriculum Implementation Questionnaire" (SCIQ), in an educational context in which a science curriculum review had recently been completed and, by so doing, ascertain the accuracy and potential value of the instrument as a curriculum delivery…

In this study, we defined and quantified the degree of cognitive conflict induced by a discrepant event from a cognitive perspective. Based on the scheme developed, we investigated the relationship between cognitive conflict and conceptual change, and the influences of students' cognitive characteristics on conflict in learning the concept of…

In this study, the cognitive characteristics of students' decision-making processes centered on phases, difficulties, and strategies are analysed in the personal dailylife context involving biological knowledge. The subjects were first year science and general high school students in Seoul, Korea; 6 female students and 7 male students. The…

The results are described of two case studies on the conceptions and classroom practice of two Portuguese physics and chemistry teachers on the role of problem solving in the teaching/learning of science. One of these teachers was a novice and the other had about 20 years of teaching experience. The data were obtained from a questionnaire, a…

This article reports on students' decision making processes and sources of knowledge in an integrated teaching and learning setting. The study was conducted in a Year 9 classroom as students undertook a 10-week solar-powered boat project and were exposed to related concepts from science, technology and mathematics. Data collection involved…

This research exercise, employing an action research model for curriculum improvement, explored the factors influencing science program delivery at an elementary school in New Zealand. Using a validated science program delivery evaluation tool, the "Science Curriculum Implementation Questionnaire" (SCIQ), as a foundation for data collection, staff…
