Multilevel Effects of Student and Classroom Factors on Elementary Science Achievement in Five Countries

This study examined the effects of individual student factors and classroom factors on elementary science achievement within and across five countries. The student‐level factors included gender, self‐confidence in science and home resources. The classroom‐level factors included teacher characteristics, instructional variables and classroom composition. Results for the USA and four other countries, Singapore, Japan, Australia and Scotland, were reported. Multilevel effects were examined through Hierarchical Linear Modelling, using the Trends in International Mathematics and Science Study 2003 fourth grade dataset. Overall, the results showed that selected student background characteristics were consistently related to elementary science achievement in countries investigated. At the student level, higher levels of home resources and self‐confidence and at the classroom level, higher levels of class mean home resources yielded higher science scores on the TIMSS 2003. In general, teacher and instructional variables were minimally related to science achievement. There was evidence of positive effects of teacher support in the USA and Singapore. The emphasis on science inquiry was positively related to science achievement in Singapore and negatively related in the USA and Australia. Recommendations for practice and policy were discussed.     

Discipline orientations of pre‐service teachers before and after student teaching

This study examined the classroom discipline orientations of pre‐service elementary teachers both before and after the student teaching experience. Prior to beginning and immediately after completing their full‐time student teaching experience, pre‐service teachers (N = 220) from three southeastern universities in the USA completed a discipline belief instrument which identified their preferred model of classroom discipline. The results showed that the student teaching experience significantly increased beginning teachers’ preferences toward a more assertive discipline model (Rules and Consequences) and decreased their preferences toward the humanistic discipline model (Relationship–Listening). These results demonstrate that the student teaching experience may be creating a dissonance in prior knowledge and beliefs, and experiences of pre‐service teachers in classrooms. The results of the study suggest that teacher education programs can help pre‐service teachers transition more smoothly into classroom teaching by providing a school–university partnership as well as more lessons and advice on handling specific classroom management situations.     

Developing a Scale of Attitudes Toward Seeking Psychological Help: Validity and Reliability Analyses

The present study was conducted to develop the scale for Attitudes Toward Seeking Psychological Help (ASPH). Four dimensions of ASPH were determined by using factor analysis, which was conducted with 356 participants. The dimensions were named as confidence for getting psychological help; beliefs about the functions of psychological help; endurance against labelling, and self-disclosure. Reliability coefficient was found as satisfactory in the scale (.88) and subscales (.76, .77, .76, and .68). Test-retest reliability was .99. Validity of the scale was examined by using discriminant validity analysis and it was observed as sufficient. The results of the study showed that ASPH has an identifiable factor structure and it is a reliable and valid scale.     

Developing epistemologically empowered teachers: examining the role of philosophy of chemistry in teacher education

History and philosophy of science have been widely promoted in science teacher education for several decades. However the application of themes from philosophy of science in science teacher education has been rather broad and not particular relative to the domain-specific features of the science in question. The purpose of this paper is to investigate how the new field of philosophy of chemistry can contribute to science teacher education. Since the beginning of the 1990s, philosophy of chemistry has emerged as a relatively new branch of philosophy of science examining the distinctive nature of chemical knowledge. Some implications of this domain in chemical education have been investigated although the research territory in this area remains underdeveloped. The paper is intended to contribute to this area of research by focusing on a particular theme, the microscopic/macroscopic relationship (or the so-called ‘supervenience’ problem) in the context of models and modelling. Literature review of students’ and teachers’ understanding of models and modelling in chemistry highlights the importance of incorporating the epistemological aspects of related chemical concepts. The implications for teacher education are discussed.     

Reconceptualizing the Nature of Science for Science Education

Two fundamental questions about science are relevant for science educators: (a) What is the nature of science? and (b) what aspects of nature of science should be taught and learned? They are fundamental because they pertain to how science gets to be framed as a school subject and determines what aspects of it are worthy of inclusion in school science. This conceptual article re-examines extant notions of nature of science and proposes an expanded version of the Family Resemblance Approach (FRA), originally developed by Irzik and Nola (International handbook of research in history, philosophy and science teaching. Springer, Dordrecht, pp 999–1021, 2014) in which they view science as a cognitive-epistemic and as an institutional-social system. The conceptual basis of the expanded FRA is described and justified in this article based on a detailed account published elsewhere (Erduran and Dagher in Reconceptualizing the nature of science for science education: scientific knowledge, practices and other family categories. Springer, Dordrecht, 2014a). The expanded FRA provides a useful framework for organizing science curriculum and instruction and gives rise to generative visual tools that support the implementation of a richer understanding of and about science. The practical implications for this approach have been incorporated into analysis of curriculum policy documents, curriculum implementation resources, textbook analysis and teacher education settings.     

Reconceptualised family resemblance approach to nature of science in pre-service science teacher education

A recent framework on nature of science (NOS) is the Family Resemblance Approach (FRA). FRA presents NOS as a cognitive-epistemic and social-institutional system with a set of categories: aims and values, scientific methods, scientific practices, scientific knowledge and social-institutional aspects of science. Although FRA has been problematised philosophically and its implications for science education have been considered by science educators, its empirical adaptations in science education are limited. In order to illustrate the educational adaptations of FRA, we refer to Reconceptualised Family Resemblance Approach to Nature of Science or RFN. We present a study based on a funded pre-service science teacher education project whose aim was to design, implement and evaluate the impact of RFN strategies. Fifteen pre-service teachers participated in a 14-week teacher education intervention that infused RFN. A 70-item questionnaire was designed to investigate the outcomes of the teacher education intervention. Individual interviews with pre-service teachers were also conducted. Quantitative and qualitative data analysis suggest that the teacher education intervention had an overall significant impact on pre-service teachers’ views of NOS. The paper contributes to the understanding of how NOS can be incorporated in science teacher education using a new orientation to NOS based on FRA.     

Drawing Nature of Science in Pre-service Science Teacher Education: Epistemic Insight Through Visual Representations

Developing pre-service science teachers’ epistemic insight remains a challenge, despite decades of research in related bodies of work such as the nature of science (NOS) in science education. While there may be numerous aspects to this problem, one critical element is that the NOS is a meta-concept that demands higher-order cognitive skills. One possible strategy to facilitate pre-service teachers’ understanding of epistemic aspects of science is visualisation. Visual representations of objects and processes can be tools for developing and monitoring understanding. Although the NOS and visualisation literatures have been studied extensively, the intersection of these bodies of literatures has been minimal. Incorporating visual tools on the NOS in teacher education is likely to facilitate teachers’ learning, eventually impacting their students’ learning of the NOS. The objective of this paper is to illustrate how the visual tools of scientific knowledge and practices aspects of the NOS can be integrated in science teacher education in order to develop pre-service teachers’ epistemic insight. The paper presents an empirical study that incorporated visual tools about the NOS in primary science teacher education. Data on 14 pre-service teachers’ are presented along with in-depth case studies of 3 pre-service teachers illustrating the influence of the teacher education intervention. The qualitative analysis of visual representations before and after the intervention as well as verbal data suggests that there was improvement in pre-service teachers’ perceptions of the NOS. Implications for future research on visualisation of the NOS are discussed.
