The purpose of this study was to investigate the possible relationships between pre-service science teachers&#039 / understanding of nature of science (NOS) and their personal characteristics / understanding of nature of scientific inquiry (NOSI), epistemological world views, self-efficacy beliefs regarding science teaching, attitudes towards science teaching, metacognitive awareness level and faith/worldview schemas. The sample of the present study were 60 PSTs that are 3rd year students at elementary science education department at a public university in the Marmara region. The sample was chosen by using purposive sampling from the PSTs enrolled in the &quot / Nature of Science and History of Science&quot / course. Using a descriptive and associational case study design PSTs&rsquo / understandings of NOS, understanding of NOSI, epistemological world views, metacognitive awareness levels, self-efficacy beliefs, attitudes toward science teaching, and faith/worldviews were determined through different questionnaires and the associations between variables were investigated. Qualitative and quantitative questionnaires were analyzed and statistical analyses were conducted to see whether there is an association between PSTs&#039 / level of understanding of NOS and their personal characteristics. The results of the study revealed that PSTs understanding of NOS and NOSI were highly related. Similarly, self-efficacy beliefs regarding science teaching, metacognitive awareness levels and faith/worldviews of the PSTs were found to be significantly related to understanding of NOS. On the other hand, there were not any significant associations between PSTs&#039 / epistemological world views, attitudes towards science teaching and understanding of NOS.

Philosophiae Doctor - PhD / The study investigated the impact of a dialogical argumentation instructional model (DAIM) as an intervention teaching strategy to assist pre-service science teachers to implement integrated science-indigenous knowledge (IK) lessons during their seven week block teaching practice at schools in the Western Cape. This imperative is found in Specific Aim 3 of the Curriculum and Assessment Policy Statement (CAPS) of the South African School Curriculum (Department of Basics Education, 2011). The study focussed on the pre-post conceptions of pre-service science teachers’ conceptions of the nature of science and the nature of indigenous knowledge. In addition the study examined pre-service teachers’ sense of self-efficacy in deploying a dialogical argumentation instructional model to implement an integrated science-IK lesson. The sample consisted of a cohort of thirty (30) Post-graduate Certificate of Education (PGCE) students training to teach at the Further Education and Training (FET) phase of school. They were a combined class enrolled for method in Natural Sciences, Life Sciences and Physical Sciences. A mixed methods approach was used to generate quantitative and qualitative data using a series of questionnaires, reflective diaries, journals and focus group interviews. Transcripts provided a rich bank of data of which only exemplars were used to highlight trends and to illustrate how theoretical constructs were used as analytical tools. The theoretical constructs used were Toulmin’s (1958/2003) Argumentation Pattern (TAP), Ogunniyi’s (1997) Contiguity Argumentation Theory (CAT) and Banduras’ Social Cognitive Theory (1986). The findings showed that the pre-service teachers appeared to overestimate their sense of self-efficacy (i.e. the ease and comfort) in using DAIM to implement a science- IK curriculum at the pre-test than at the post-test. The study also identified important implications for policy, teacher training programmes, teaching practice, pre-service science teachers, learners and further research. Furthermore, the pre-service reflective experiences indicated their increased awareness of the challenges and successes related to using dialogical argumentation to integrate a science-IK lesson. The most important contribution of this study to an argumentation paradigm was the emergence of a visual model called the Pyramid Argumentation Model that succinctly connected the apparent disparate module units in a holistic way (To be discussed in follow-up reports). The findings revealed numerous complexities as the participants navigated their own cosmologies of a scientific worldview and that of their indigenous knowledge worldview. Finally, the findings have not only corroborated the findings in earlier studies with respect to the merits and demerits of argumentation instruction but also identified various challenges that prospective and even practicing teachers might encounter in an attempt to make school science relevant to the sociocultural environment of learners especially those living in indigenous or traditional societies like the participants in this study.

The purpose of this explanatory sequential mixed methods study was fourfold: examine the pre-service science teachers' pedagogical orientations about science teaching; examine the pre-service science teachers' beliefs about science teaching; establish the extent to which the pre-service science teachers' pedagogical orientations correlate with their beliefs; and establish factors that shape the pedagogical orientations and beliefs of pre-service science teachers. A sample comprised 140 secondary school pre-service science teachers at three universities in Zambia. There were 102 males and 38 females. In the first phase, data were collected using the Pedagogy of Science Teaching Test (POSTT) that was adapted to suit the Zambian curriculum, and the Teacher Beliefs Interview (TBI) protocol. Whereas, in the second phase, a semi-structured interview was used to collect data. Twelve pre-service science teachers were interviewed to solicit in-depth information on the findings from the POSTT and TBI protocol.

The aim of this study was to examine the relationships among pre-service science teachers&rsquo / personality, self-regulation, and teaching self-efficacy by proposing and testing a comprehensive conceptual model. In the model, it was hypothesized that personality traits are directly linked to pre-service science teachers&rsquo / self-efficacy and academic self-regulation, and pre-service science teachers&rsquo / academic self-regulation is directly related to their self-efficacy. A total of 1794 pre-service science teachers (876 males and 905 females) from 27 education faculty partic ipated in the study. Self-efficacy (i.e. self-efficacy for student engagement, for instructional strategies, and for classroom management), academic self-regulation (i.e. achievement goals, task value, control of learning beliefs, test anxiety, metacognitive self-regulation, effort regulation, and peer learning), and personality trait (i.e. Neuroticism, Extraversion, Openness, Agreeableness, and Conscientiousness) were assessed by self-report instruments. The results of the path analysis revealed that agreeableness, neuroticism, performance approach goals, and use of metacognitive strategies were positively linked to different dimensions of self-efficacy, namely self-efficacy for student engagement, instructional strategies, and classroom management. In general, while agreeableness and neuroticism were found to be positively associated with different facets of academic self-regulation and self-efficacy, openness was found to be negatively linked to these adaptive outcomes.

The purpose of this study was to investigate the preservice science teachers&rsquo / perceived technological pedagogical content knowledge (TPACK) on genetics. More specifically, the purpose was to examine the relationships among the components of TPACK and genetics knowledge of the preservice science teachers. Moreover, findings the effect of the demographic information on perceived TPACK was also aimed. This study was conducted with preservice science teachers who were enrolled in elementary science education department of Education Faculties of eight public universities located in Central Anatolia. 1530 preservice science teachers participated to the study. There were two instruments used in this research which were perceived TPACK questionnaire, which was later adopted by the researcher as perceived TPACK on genetics, and genetic concepts test. v Data were analyzed by using descriptive and inferential statistics. In order to answer the first research question, descriptive information about the components of TPACK was given. Correlational analyses were used to identify the relationship between each component of the perceived TPACK on genetics and their genetic knowledge. Another correlational analysis was conducted for the third research question which seeks the relationships among the components of the TPACK. Moreover, MANOVA was conducted to investigate the impact of gender and year of enrollment on perceived TPACK on genetics of preservice science teachers. The results revealed that genetic knowledge was correlated with each component except the perceived project specific technology knowledge. Moreover, there were positive significant correlations among the components of the TPACK. According to the MANOVA results, the mean scores of male and female preservice science teachers differ in five components of TPACK, namely project specific technology knowledge, pedagogical knowledge, pedagogical content knowledge, technological content knowledge and technological pedagogical content knowledge. The results of MANOVA for year of enrollment revealed that the mean ETK, GTK, PSTK, and CK scores of participants with different year of enrollment differ significantly.
