Since the first use of ‘scientific literacy’ in the late 1950s, numerous science educators and policy makers have reconceptualised the term to such an extent that it has been described as being ‘ill-defined and diffuse’. Despite this lack of clarity, the term is the focus of curriculum standards in many countries and is at the heart of international comparisons of student attainment including the Organisation for Economic Cooperation and Development’s (OECD) Programme for International Student Assessment (PISA) study. Uncritical use of the term masks the existence of deep-seated philosophical clashes that hinder reform of science education in many countries throughout …

This paper sets out to provide an overview of scientific literacy specifically related to whether emphasis is placed on the ‘science’ or the ‘literacy’ aspect, accepting that literacy, wherever used, is wider than simply reading and writing. It does this from a general rather than a country perspective. The emphasis in giving meaning to scientific literacy is placed on the literacy component in recognition of the trend towards relating scientific literacy to skills and values appropriate for a responsible citizen. Rejected is a consideration that scientific literacy is related to an emphasis on the acquisition of content and this is …

This paper draws attention to the literature in the areas of learning, specifically, constructivism, conceptual change and cognitive development. It emphasizes the contribution of such research to our understanding of the learning process. This literature provides guidelines for teachers, at all levels, in their attempt to have their students achieve learning with understanding. Research about the constructive nature of students’ learning processes, about students’ mental models, and students’ misconceptions have important implications for teachers who wish to model scientific reasoning in an effective fashion for their students. This paper aims to communicate this research to teachers, textbook authors, and college …

The purpose of this study was to investigate Thai students’ understanding of dilution and related concepts. The literature suggests that a complete understanding of chemistry concepts such as dilution entails understanding of and the ability to integrate mental models across three levels of representation: the macroscopic, sub-microscopic and symbolic. In this work students’ understanding was probed using the interview about events (IAE) approach employing open-ended questions, and also by analysis of student descriptions, and drawings. The research findings suggest that all students were able to answer openended questions related to dilution and related concepts. Less able students presented representations at …

It is generally accepted that the environmental education deals with a wide range of environmental experiences, methods and processes. Teaching the subject of the environment should not be considered as an easy task. It should not only cover pure ecology education; but also include the citizenship responsibilities and the problems that are sourced from other interdisciplinary factors. Therefore teachers should have the responsibility to facilitate environmental issues. Hitherto no researcher has undertaken a comprehensive study that focuses on environmental education in teacher training programs. This study aims to detect basic environmental knowledge of Turkish teacher candidate at the onset of …

Based on students‟ alternative conceptions of the topics „electric circuits‟, „electric charge flows within an electric circuit‟, „how the brightness of bulbs and the resistance changes in series and parallel circuits‟, the current study aims to present a combination of different conceptual change methods within four-step constructivist teaching model. Therefore, the author assumes that such a design may give a chance to eliminate students‟ alternative conceptions fully. Also, some suggestions were made for further research.

In this decade of Education for Sustainable Development, it is timely to consider the methodological issues associated with researching this topic not only with adults but also with the young children who, as members of the next generation, will experience the success or otherwise of current environmental sustainability efforts. We argue that it is important when making methodological choices to recognize that both the sustainability issues themselves and the way individuals learn about these issues, are socially and culturally constructed. In this article we are interested in ways of gaining representations of individuals’ mental constructions of environmental sustainability issues. We …

With the increased global awareness of the negative impact of scientific, technological and industrial activities on the environment and copious examples of sustainable practices existing in many an indigenous community, the new South African science curriculum statement has called on science teachers to integrate school science with the Indigenous Knowledge Systems (IKS). In response to this call, this study used an Argumentation-Based course (A-B course) to enhance teachers’ understanding of the Nature of Science (NOS) and IKS and their ability to integrate science and IKS in their classrooms. Nine teachers participated in the course over a six-month period. Using questionnaires …

The article aims to introduce Environmental Education (EE) in Finland and to discuss how it has been taken into account in Finnish nature schools. Firstly, we present EE models used in Finland. Thereafter we describe a qualitative case study on EE in nature schools (NS). The aim of the study was to get information for the development of EE. The research questions were: Who are the visitors to NSs? What are the educational aims in NSs? What kind of educational methods and approaches do NS teachers use? The resultant data for the questions from 1 to 3 is based on …

The study of teachers’ beliefs forms part of the process of understanding how teachers conceptualize their work which in turn is important to the understanding of teachers’ practices and their decisions in the classroom. A growing body of research argues that teachers’ beliefs should be studied within a framework that is aware of the influence of culture. These studies also argue that teachers’ beliefs and practices cannot be examined out of context. This shows that the relationship between teachers’ beliefs and their practices is complex and context dependent. Some researchers have found consistencies between teachers’ beliefs and their practices whilst …
