This study examined the effect of diaries on self-regulation strategies of the pre-service science teachers. The participants of the study were 60 pre-service science teachers, 30 of which were in the experimental and the remaining 30 were in the control group. The Pintrich’s self-regulation model was taken as a basis in the study. The Pintrich’s model of self-regulation includes 3 general categories of strategies: (a) cognitive learning strategies, (b) metacognitive or self-regulatory strategies to control cognition, and (c) resource management strategies. In the study, the pre-service science teachers in the experimental group reported the self-regulation strategies they used for daily …

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 …

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 …

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 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 …

The purpose of this study was to determine the predictors of student grades in introductory physics courses utilizing problem-based learning (PBL) approach and traditional lecturing. The study employed correlational/predictive methods to investigate and describe/explain relationships of students’ physics grades with their expectations, attitudes, epistemological beliefs about physics and physics learning, and demographic variables. The subjects involved in this study were 264 freshmen engineering students (PBL, n = 100; traditional, n = 164) at Dokuz Eylül University (DEU) in Izmir, Turkey. All students were surveyed at the beginning and at the end of the spring 2007 semester using the Maryland Physics …

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 …

Children’s knowledge about human anatomy can be examined through several different ways. Making a drawing of the internal features of the human body has been frequently used in recent studies. However, there might be a serious difference in results obtained from a general instruction to students (What you think is inside your body) and specific (e.g. Draw bones that are inside your body) instruction. We examined relationships between these two types of instructions using drawings of the urinary and endocrine systems as the examples with pupils aged 10-14 years. An ANCOVA showed significant relationships between general and special instruction, but …

Recent research suggests that the issue of global warming is one of great concern for Australian children. This point to the need for effective teaching about this issue. Children should be properly informed about actions that help reduce carbon emissions as this may give them a sense of empowerment and go some way to alleviating concerns. This study followed the development in the knowledge of global warming of 29 primary school students in year 6 (the final year of primary) from two regional Australian schools over one school term. A hands-on science unit dealing specifically with global warming was prepared …

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 …
