Turkish Pre‐Service Science Teachers’ Views on Science–Technology–Society Issues

The international science education community recognises the role of pre‐service science teachers’ views about the interdependence of Science, Technology, and Society (STS) in achieving scientific literacy for all. To this end, pre‐service science teachers’ STS views signal the strengths and the weaknesses of science education reform movements. Turkey, a country that follows the international reform movement, aims at improving citizen’s understanding of the STS interdependence to enable them to fully participate in an industrialised, democratic society. This study explores the Turkish pre‐service science teachers’ views (n = 176) on STS issues and discusses the ongoing reform efforts’ strengths and weaknesses within the context of the study findings. Data were collected through an adopted “Views on Science–Technology–Society” instrument. Analysis revealed that many participants held realistic views on science, technology, and society interdependence, while their views on technology and the nature of science were differed. Some viewed technology as an application of science, and some viewed science as explanatory and an interpretation of nature. Most agreed that the scientific knowledge is tentative but they did not present a thorough understanding of the differences between hypotheses, laws, and theories.

The Nature of Pre-service Science Teachers’ Argumentation in Inquiry-oriented Laboratory Context

The aim of this study was to investigate the kinds of argumentation schemes generated by pre-service elementary science teachers (PSTs) as they perform inquiry-oriented laboratory tasks, and to explore how argumentation schemes vary by task as well as by experimentation and discussion sessions. The model of argumentative and scientific inquiry was used as a design framework in the present study. According to the model, the inquiry of scientific topics was employed by groups of participants through experimentation and critical discussion sessions. The participants of the study were 35 PSTs, who teach middle school science to sixth through eighth grade students after graduation. The data were collected through video- and audio-recordings of the discussions made by PSTs in six inquiry-oriented laboratory sessions. For the analysis of data, pre-determined argumentation schemes by Walton were employed. The results illustrated that PSTs applied varied premises rather than only observations or reliable sources to ground their claims or to argue for a case or an action. It is also worthy of notice that the construction and evaluation of scientific knowledge claims resulted in different numbers and kinds of arguments. Results of this study suggest that designing inquiry-oriented laboratory environments, which are enriched with critical discussion, provides discourse opportunities that can support argumentation. Moreover, PSTs can be encouraged to support and promote argumentation in their future science classrooms if they engage in argumentation integrated instructional strategies.

The importance of teacher–student interpersonal relationships for Turkish students’ attitudes towards science

The purpose of this study was to examine associations between Turkish high school students’ perceptions of their science teachers’ interpersonal behaviour and their attitudes towards science. Students’ perceptions of the teacher–student interpersonal relationship were mapped with the Questionnaire on Teacher Interaction (QTI), which uses two relational dimensions: influence and proximity. Data on Students’ subject‐related attitudes were collected with the Test of Science Related Attitudes (TOSRA). A total of 7484 students (Grades 9 to 11) from 278 science classes (55 public schools) in 13 major Turkish cities participated in the study. Multilevel analyses of variance indicated that influence was related with student enjoyment, while proximity was associated with attitudes towards inquiry and with enjoyment.

Science Teaching Efficacy Beliefs

Teacher self-efficacy is considered one of the most powerful constructs in explaining both student and teacher behaviors, including the goals they set for themselves, their persistence in the face of difficulties, and the effort they invest. For over the past three decades, a number of educational studies have emerged about meaning, measurement, and correlates of this construct, as well as application in different domains like science teaching efficacy. This chapter focuses on science teaching efficacy beliefs. First, we present the historical background of self-efficacy including origins, definition, and distinctive features of self-efficacy beliefs. Next, we focus on teachers’ sense of efficacy, highlighting the conceptual framework and critical measurement issues. We then review research on science teaching efficacy by summarizing major findings. We conclude our chapter by offering recommendations for future research.

Elementary Students’ Scientific Epistemological Beliefs in Relation to Socio-Economic Status and Gender

This study investigated students’ scientific epistemological beliefs in relation to socio-economic status (SES) and gender. Data were obtained from 1,152 eight grade Turkish elementary school students using Scientific Epistemological Beliefs instrument. Canonical correlation analysis indicated that students with a working mother and educated parents as well as greater number of books at home together with a separate study room are more likely to have tentative views and less likely to have fixed views about science compared to students with unemployed mother, uneducated parents, less books at home, and no separate study room. Generally, results revealed while family SES correlated positively with tentative views, it was negatively associated with fixed views, implying that students from high SES family were more likely to believe that knowledge is uncertain and not handed down by authority compared to students from low SES family. This study, however, failed to indicate any relationship between father work-status, buying daily newspaper and epistemological beliefs. In addition, Multivariate Analysis of Variance indicated that boys more likely to have tentative beliefs compared to girls.

Preservice Elementary Teachers' Self-Efficacy Beliefs and Their Conceptions of Photosynthesis and Inheritance.

The purpose of this study was to examine preservice elementary teachers’ understanding of the concepts of photosynthesis and inheritance, to explore their self-efficacy beliefs in the teaching of science, and to investigate the relationship between these two issues. Data was gathered through the use of a misconception instrument and science teaching efficacy beliefs instruments. Seventy-nine preservice elementary teachers participated in this study. The results showed that participants held alternative conceptions regarding photosynthesis and inheritance and have generally positive self-efficacy beliefs regarding science teaching. The results also suggested that those participants with fewer alternative conceptions regarding photosynthesis had relatively high personal science teaching efficacy. Teachers are clearly a central component for student success in learning science; however, in 1983, Feistritzer and Boyer reported that among elementary teachers, understanding science concepts was at a low level. Previous studies have shown that elementary teachers often have negative attitudes toward science (Shrigley, 1974), have science anxiety (Czerniak & Chiarelott, 1990), have low science interest (Tilgner, 1990), and do not have confidence in their ability to teach science (DeTure, Gregory, & Ramsey, 1990). Studies also have found that elementary teachers generally possess a low level of knowledge regarding the concepts, facts, and skills concerning science (Stevens & Wenner, 1996; Victor, 1962; Wenner, 1993). A number of studies have documented that both preservice and inservice elementary teachers frequently hold alternative conceptions (or misconceptions) for a variety of science concepts and harbor misunderstandings (Atwood & Atwood, 1996; Schoon, 1993; Schoon & Boone, 1998). This often causes elementary teachers to avoid teaching science to children (Czerniak & Chiarelott, 1990; Westerback, 1982) or to spend less time teaching science in comparison to other subjects (Westerback, 1982).

The Effect of Explicit Embedded Reflective Instruction on Nature of Science Understandings in Advanced Science Students.

The purpose of this study is to investigate the effectiveness of explicit-embedded-reflective (EER) instruction in nature of science (NOS) understandings of ninth-grade advanced science students. This study was conducted with 71 students, who were divided into three groups, by using non-equivalent quasi-experimental design. In the treatment groups, the EER teaching was conducted, while in the comparison group NOS instruction was carried out in the same time interval by lecturing, demonstration and questioning strategies. Views on Nature of Science Questionnaire-Form C and follow-up interviews were used for data collection. Categorisation of the participants’ profiles on aspects of the NOS was used for data analysis. According to the results, participants had misunderstandings about ‘scientific methods’, ‘laws and theories’ and ‘observation and inference’, while they had expert views on ‘the role of creativity and imagination’ in the beginning of the study. For changing naive NOS understandings, the EER approach was found to be effective.

The Pedagogy of Argumentation in Science Education: Science Teachers' Instructional Practices.

ABSTRACT Argumentation has been a prominent concern in science education research and a common goal in science curriculum in many countries over the past decade. With reference to this goal, policy documents burden responsibilities on science teachers, such as involving students in dialogues and being guides in students’ spoken or written argumentation. Consequently, teachers’ pedagogical practices regarding argumentation gain importance due to their impact on how they incorporate this practice into their classrooms. In this study, therefore, we investigated the instructional strategies adopted by science teachers for their argumentation-based science teaching. Participants were one elementary science teacher, two chemistry teachers, and four graduate students, who have a background in science education. The study took place during a graduate course, which was aimed at developing science teachers’ theory and pedagogy of argumentation. Data sources included the participants’ video-recorded classroom practices, audio-recorded reflections, post-interviews, and participants’ written materials. The findings revealed three typologies of instructional strategies towards argumentation. They are named as Basic Instructional Strategies for Argumentation, Meta-level Instructional Strategies for Argumentation, and Meta-strategic Instructional Strategies for Argumentation. In conclusion, the study provided a detailed coding framework for the exploration of science teachers’ instructional practices while they are implementing argumentation-based lessons.

Analysing Middle School Students’ Perceptions of Their Science Classroom In Relation to Attitudes and Motivation

In recent years, education has been blamed for graduates not being sufficiently able to apply their knowledge to solve complex problems in working contexts. Therefore, the development and implementation of instructional practices that foster students’ skills to communicate, think and reason effectively, make judgements about the accuracy of information, solve complex problems and work collaboratively in diverse teams, remains an important challenge for today’s education (Pellegrino, Chodowsky, & Glaser, 2001).

Preservice science teachers’ collective efficacy in a science methods course

Abstract This study investigated how preservice teachers develop collective efficacy when preparing lesson plans for a science methods course, and how this collective efficacy changed over time. The data were collected from four preservice science teachers working in a group to fulfil the requirements of the course. Findings revealed that four factors, including collaborative work, sharing the same goal, attitudes towards group work and group cohesion, played an important role in the development of collective efficacy among preservice teachers. The study also showed that collective efficacy improved continuously over the semester.
