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…

Green chemistry developed historically from twelve industrial principles for research chemists. Recently, interest has grown to begin introducing these principles in science classrooms even at the secondary and pre-secondary school levels. However, teachers must do significant work to adapt and translate green chemistry from the industrial or…

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…

Over the past several decades, science education reforms have called for students to develop appropriate views of the nature of science and have a comprehensive understanding of subject matter. Additionally, education research has demonstrated that teachers must have appropriate views of the nature of science and strong content knowledge as…

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 goal of this study was to examine the way preservice science teachers depict and develop their understanding of nature of science (NOS), from the perspective of the family resemblance approach (FRA). FRA defines NOS as a Cognitive-Epistemic and Social-Institutional system. Appling the dual-analytic approach via reflective drawing analysis, we…

The purpose of this paper is to investigate the effectiveness of pedagogical content knowledge (PCK)-based nature of science (NOS) teaching on pre-service science teachers' (PSTs) NOS views. The study is grounded by conceptual change and experiential learning theory. It is also framed by the teacher professional knowledge and skill (TPK&S) PCK…

This paper addresses two methodological issues related to the assessment of teachers' views of science. The first concerns the distinction between the "nature of science" (NOS) and the nature of "scientific inquiry" (SI): should the points related to NOS and those related to SI be analyzed independently? The second concerns the…

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…

This study reviewed the green and sustainable chemistry education (GSCE) research that provided training at the tertiary level from 2000 to 2024. The Web of Science and ERIC databases were screened using title and abstract review. In total, 49 studies were analysed. The analysis instrument has two main parts, namely, general characteristics of the…

Competency levels around scientific literacy for high school students in the United States are insufficient for students' future ability to be competent consumers and voters. The purpose of this action research study was to explore how students were being exposed to scientific literacy concepts in high school science courses in the United States.…

The paper reports about a study that examines changes in teachers' incorporation of epistemic practices in their design of engineering lessons and compares them to their views about the nature of engineering knowledge across 100 hours of professional development. Nineteen K-8 teachers in the USA, who were new to teaching engineering as part of a…
