Purpose -- This study is part of a comprehensive investigation conducted in Malaysia, examining science teachers' understanding of the Nature of Science (NOS) and their ability to translate this knowledge into Pedagogical Content Knowledge (PCK) for NOS. This paper specifically examines how teachers apply their NOS knowledge to develop NOS PCK in…

This article reports on the effect of textbook analysis as a tool of teacher professional development on nature of science (NOS) understanding of 10 science teachers in South Africa. The teacher professional development program (TPDP) was based on an explicit reflective methodology of textbook analysis and conducted online due to the Covid-induced…

This study examined pre-service primary teachers' (PPTs) initial NOSI conceptions and their evolution after the immersion in a specific teaching module focused on inquiry and NOSI. The participants were 40 PPTs attending a science education course during a semester. The study consisted of a pre-test/post-test design approach framed qualitative…

Advancing inquiry-based science education is crucial for fostering sustainable development among science teachers. Integrating digital technology into teacher preparation programs is essential due to its widespread use in inquiry-based methodologies. Understanding the Nature of Scientific Inquiry (NOSI) is fundamental for pre-service science…

This paper explores the influence of Science Teaching Orientations (STOs) on Teacher Professional Knowledge (TPK) domains of five in-service Malawian secondary school science teachers. The study was grounded within Friedrichsten et al.'s (2011) definition of STOs and Gess-Newsome's (2015) conceptualization of TPK. We gathered data using…

The purpose of the present study was to reveal the effectiveness of the Nature of Science (NOS) embedded in Argument-Driven Inquiry (ADI) instructional method on pre-service science teachers' (PSTs) content knowledge and self-efficacy in evolution theory. The study was a mixed-method study in which the qualitative data collection and analysis was…

The topic 'photosynthesis' contains many intangible and abstract scientific concepts, regarding which students hold many preconceptions. Conceptual learning is a process of co-creation and flow that requires the teachers' higher educational level on conceptual teaching. The present research considers photosynthesis as an example. Results of Ball's…

Students at upper secondary and college level in many countries are introduced to quantum physics (QP) in a mostly mathless course. Research shows that addressing epistemological and philosophical aspects would be beneficial for novice students' conceptual understanding. However, physics teachers seldom address these nature of science (NOS)…

The present study elaborates on a domain-specific approach to NOS (Nature Of Science) and employs a NOTSs (Nature Of The Sciences) agenda to investigate how Greek in-service physics teachers understand the unique features of school physics and biology. Our theoretical framework focuses on the notion of worldview and important differences that…

Due to the lack of success of German students in recent program for international student assessment (PISA) studies since 2001, the question arises whether German teacher training has an impact on this performance. This publication is based on a systematic review which deals with German-language publications of various PISA-relevant areas within…

Science teacher's self-efficacy has been at the center of many investigations on students' achievement in science, teacher burnout, and teacher performance. While overly studied, this construct has not been examined with scientific literacy in depth. Thus, this study aims to identify the influence of science teacher's scientific literacy on their…

Research in teacher education has given increasing attention to pedagogical content knowledge (PCK) as a theoretical construct that describes necessary knowledge for teachers to teach specific content. This research study aims to examine whether an understanding about the nature of science (NOS) correlates with orientation to teaching science…

This study, which was conducted in 2016-2017 academic year, scrutinized the impact of a purposefully designed professional development program titled 'NOS-PD' on the understandings of the Nature of Science (NOS) via instructional practices. Specifically, the purpose of this qualitative multiple-case study was to delineate the impact of a NOS…

The mole concept is one of the fundamental concepts in chemistry. However, a number of studies carried out in various countries have shown that teachers and learners face many difficulties in teaching and learning the concept. One of the underlying sources of teaching and learning difficulties of the mole concept identified in literature is the…

This study investigates the preservice elementary teachers' ability to use the components of an argument structure on a given science topic as well as the quality of the developed argument during their sophomore and senior year. In doing so, the study also aimed to discuss the effect of teacher education programs on the development of…
