Decision making is influenced by multiple factors, especially when approaching controversial socio-scientific issues, such as stem cell research. In the present study, we used qualitative data from 132 college student papers in a biotechnology course to investigate how students made decisions about stem cell research issues. Students indicated…

Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

This paper introduces the four research papers in this paper set, which all derive from a European research project, STTIS (Science Teacher Training in an Information Society). The central concern of the project was to study curriculum innovations in science, and to investigate ways in which teachers transform these innovations when putting them…

Within the overall STTIS (Science Teacher Training in an Information Society) framework, this paper focuses on transformations of innovative teaching of optics, following a recommended change of approach to optics in the French curriculum. The empirical investigation of how teachers responded to this change, the main results of which are briefly…

This Italian contribution to the STTIS (science teacher training in an information society) investigations of transformations of curriculum innovations looks at the implementation of the use of real-time experiments and images (RTEI), in which computer data acquisition and display is built in to aspects of science teaching. Certain critical…

This Spanish contribution to the STTIS (Science Teacher Training in an Information Society) investigations of transformations of curriculum innovations studies the implementation of a particular innovative teaching sequence on energy degradation in Spanish secondary schools. The paper describes the transformations found in teachers'…

This paper, from the UK group in the STTIS (Science Teacher Training in an Information Society) project, describes research into the nature of teachers' transformations of computer modeling, and the development of related teacher training materials. Eight teacher case studies help to identify factors that favor or hinder the take-up of innovative…

This study focused on informal reasoning regarding socioscientific issues. It sought to explore how content knowledge influenced the negotiation and resolution of contentious and complex scenarios based on genetic engineering. Two hundred and sixty-nine students drawn from undergraduate natural science and nonnatural science courses completed a…

This paper reports the results of applying a particular analytical perspective to data from an interview study: a typology of learning impediments informed by research into learning and students' ideas in science. This typology is a heuristic tool that may help diagnose the origins of students' learning difficulties. Here it is applied to data…

Project-based learning (PBL), which is increasingly supported by information technologies (IT), contributes to fostering student-directed scientific inquiry of problems in a real-world setting. This study investigated the integration of PBL in an IT environment into three undergraduate chemistry courses, each including both experimental and…

The purpose of this study was to explore how science teachers' epistemological beliefs and teaching goals are related to their use of lab activities. Research questions include: (1) What are the teachers' epistemological beliefs pertaining to lab activities? (2) Why do the science teachers use lab activities? (3) How are the teachers'…

This paper offers an account of, and findings from, an approach to designing and evaluating an instructional sequence set in the context of Newton's third law. The design of the sequence draws upon conceptual change theory and the concept of the "bridging analog" is extended to introduce the notion of a "bridging representation" Attention is also…

National assessments and other investigations have drawn attention to the fact that there is considerable room for improvement in science teaching and learning. This article describes, exemplifies, and discusses a research program set up to address this unsatisfactory state of affairs. Briefly, the idea of the program is that researchers in…

In some contexts, a photograph may be worth a thousand words. Previous research revealed a dialectical character of photographs: they simultaneously lack determinacy and exhibit an excess of meaning. The purpose of this study was to understand how, under this condition, high school students interpret photographs that were accompanied by different…

What science-related knowledge is actually used by nurses in their day-to-day clinical reasoning when attending patients? The study investigated the knowledge-in-use of six acute-care nurses in a hospital surgical unit. It was found that the nurses mainly drew upon their professional knowledge of nursing and upon their procedural understanding…
