Research on playfulness, science, and creativity suggests that there is a connection between having positive background experiences with science and the development of interest in science. However, there is little empirical research on where, how, and when teachers’ interests in science develop. The purpose of this research was to explore connections between preservice elementary teachers’ background science experiences and interest in science. Subjects were 53 preservice teachers in two sections of a science methods course. The data were collected by administering a self-report Science Background Experiences Survey. Students with low and high initial interest in science were significantly different on …

This study examined the similarities and differences among 171 Grade 7-12 science teachers from three different countries (54 U.S, 63 Bolivian, and 54 Turkish) with respect to their attitudes toward environmental education (EE) and instructional practices. The instrument employed explored how teachers‘ knowledge, instructional practices, decisionmaking process, and cultural features influenced their EE attitudes and praxis. The instrument, which was translated into Spanish and Turkish and then back into English, contained a personal data form that included demographic questions and a three-part questionnaire. Based on the analysis completed, significant differences were found between these three countries with respect to 1) …

Sociocognitive conflict has been used as a teaching strategy which may contribute to change students’ conceptions about science concepts. The present paper aims at investigating the structure of the dialogic argumentation developed by students, when they are involved in science teaching sequence that have been designed to change their conceptions through sociocognitive conflict strategy. For this purpose, teaching sequence targeted at the elaboration of students’ conceptions about floating and sinking -based on sociocognitive conflict processes- were prepared and implemented among 14 years old students. Next, the dialogues which the students had during the teaching sequence were analysed with the help …

Determination of conceptual problems which may cause alternative conceptions in science and technology textbooks is significant to increase in success of pupils and teachers. It is a vital issue to arrange books in a way removing or decreasing these faults in order to improve a better education via textbooks. This study aims to determine conceptual problems which may cause alternative conceptions in biology topics in science and technology textbooks of primary schools. In this study, the units of each textbook were analyzed page by page according to document examination method and conceptual problems were determined. The founded conceptual problems have …

This paper describes the design of an educational module which aims to raise awareness and change the attitudes of elementary school students about focal endangered species in protected areas. The proposed design builds on, and extends the General Teaching Model. The educational module which was developed through this approach was pilot-tested in two Greek elementary school classes, involving 29 students who provided their opinion through a questionnaire. The results verify that the educational module had a significant effect on the cognitive level and the attitudes of the students. Therefore, it is argued that the proposed design approach can form the …

In the United States and around the world, calls for educational reform stress the need for a scientifically literate population, prepared for the twenty-first century workforce. These calls have translated into new curricula, which in isolation, are not enough? Teachers play an essential role in the development of scientifically literate citizens. Their purposes for teaching science act as filters for acceptable learning and teaching activities. This paper examines the congruence of eight private school teachers’ purposes for teaching science, and aspects of scientific literacy in the Middle Eastern country of Lebanon. Findings are discussed in light of contextual factors that …

The late 20th century and beginning of 21st century have witnessed unprecedented rapid economic development due to advances in technology and globalization. In response to this development, a renewed call for science literacy has become louder in the USA and many other countries. Common to all science education reforms around the world is emphasis on achieving science literacy by all children before high school graduation. This paper first reviews definitions of science literacy in the literature; it then examines the status of science literacy in the USA and other countries. Following the above, this paper then presents a new notion …

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 …

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 …
