In this paper, we present and apply a multi-level method for discourse analysis in science classrooms. This method is based on the structure of human activity (activity, actions, and operations) and it was applied to study a pre-service physics teacher methods course. We argue that such an approach, based on a cultural psychological perspective,…

This opinion piece paper urges teachers and teacher educators to draw careful distinctions among four basic learning goals: learning science, learning about science, doing science and learning to address socio-scientific issues. In elaboration, the author urges that careful attention is paid to the selection of teaching/learning methods that…

The call for inquiry science to be a part of the school science curriculum is popular in many parts of the world. While some research in this area revealed success stories of students' learning when they are engaged in student-directed, open-ended scientific inquiry activities, others are more sceptical about how these activities impact students'…

On several levels it can be said that the act of modelling in science is inherently an argumentative act. That is, in virtually all aspects of modelling, from developing a question to judging between competing models that might answer that question, an individual is engaged in persuasive acts. Those acts may be private or public. They may be…

This article describes a qualitative study of college mathematics and science faculty (n = 6) and their engagement in a reform-based program, Japanese lesson study (LS), to change their teaching practices. LS is a process in which a team of four to six teachers jointly design, teach, observe, analyze, and revise a single class lesson. A series of…

Contemporary genomics research will impact the daily practice of biology teachers who want to teach up-to-date genetics in secondary education. This article reports on a research project aimed at enhancing biology teachers' expertise for teaching genetics situated in the context of genetic testing. The increasing body of scientific knowledge…

Compared with research on the role of student engagement with expert representations in learning science, investigation of the use and theoretical justification of student-generated representations to learn science is less common. In this paper, we present a framework that aims to integrate three perspectives to explain how and why…

The theme of this paper is students' interest in future natural sciences-related careers. It is based on data from the Programme for International Student Assessment survey that in 2006 focused attention on the science literacy achievements of students. The paper uses the methods of linear regression modelling and structural equation modelling in…

The idea that chemical knowledge can be represented in three main ways: macro, submicro, and symbolic (chemistry triplet) has become paradigmatic in chemistry and science education. It has served both as the base of theoretical frameworks that guide research in chemical education and as a central idea in various curriculum projects. However, this…

International assessments provide important knowledge about science education and help inform decisions about policies, programmes, and practices in participating countries. In 2006, science was the primary domain for the Programme for International Student Assessment (PISA), supported by the Organisation for Economic Cooperation and Development…

This paper describes the expressed models that children aged 7, 11, and 14 years have about micro-organisms and microbial activity. These were elicited using a variety of data collection techniques that complemented each other, resulting in a rich dataset, and provided information about the level of knowledge and progression of ideas across the…

The purpose of this article is to provide an overview of the nature of models and their uses in the science classroom based on a theoretical review of literature. The ideas that science philosophers and science education researchers have in common about models and modelling are scrutinised according to five subtopics: "meanings of a model",…

This paper describes the process for creating and validating an assessment test that measures the effectiveness of instruction by probing how well that instruction causes students in a class to think like experts about specific areas of science. The design principles and process are laid out and it is shown how these align with professional…

Undergraduate students pursuing a three-year marine biology degree programme (n = 86) experienced a large-group drama aimed at allowing them to explore how scientific research is funded and the associated links between science and society. In the drama, Year 1 students played the "general public" who decided which environmental research areas…

Principles of direct current have long been recognised in the literature as presenting difficulties for learners. Most of these difficulties have been reported in the context of the traditional electron flow model. In this paper, an alternative approach for high school students using a field model is explored. Findings from a range of short pilot…
