This study analyzes the elements of the nature of science (NOS) with respect to environmental issues in middle-school science textbooks, covering three collections (nine and 12 books) from South Korea and Brazil, respectively. Content analysis was used to categorize the elements of the NOS using the reconceptualized family resemblance approach to…

This research investigated the effect of project-based learning (PjBL) on students' conceptual understanding of mechanics. For this purpose, a quasi-experimental research design was conducted with 50 ninth-grade students at Nazarbayev Intellectual School in Kazakhstan. We used the force concept inventory test to measure students' conceptual…

The paper reports an empirical study on the relationship between middle school students' understanding of nature of science (NOS) and their metacognitive awareness. The reconceptualised family resemblance approach to the nature of science (RFN) (Erduran & Dagher, 2014; Kaya & Erduran, 2016) as a holistic framework that covers science as…

As students read scientific texts created in generative artificial intelligence (GenAI) tools, they need to draw on their epistemic knowledge of GenAI as well as that of science. However, only a few research discussed multimodality as a methodological approach in characterising students' ideas of GenAI-science epistemic reading. This study…

Students' understanding of nature of science (NOS) has been largely examined primarily in written or verbal modes. The visual, verbal, and written modes are essential for students' meaning-making of NOS. However, research has sidelined the interaction among these three modes in understanding students' collaborative discourse of NOS. Informed by…

This study aims to investigate the effect of the teaching model developed for hot conceptual change on middle school 7th-grade students' understanding of the Nature of Science (NOS) aspects. In this qualitative and exploratory study, activities were carried out with 24 students of two classes in a village school in the South Marmara region using a…

Energy is one important concept in physics, but science education research has repeatedly shown that students struggle to develop a full understanding of energy. Especially challenging for students is the notion of potential energy. Overwhelmed by the sheer number of potential energy forms, students struggle to make connections between them.…

The purpose of this study is to see how the inquiry-based nature of science (NOS) argumentation (IB-NOSA) instructional model affects scientific literacy skills. This research used a quasi-experimental method. The design of this research is a pretest-posttest control group design. This study describes the significance of the differences between…

Despite decades of research, NOS is still rarely explicitly and accurately taught in K-12 schools (Abd-El-Khalick & Lederman, 2023). Teachers often address NOS ineffectively as a result of inadequate knowledge of NOS and science content (Wahbeh & Abd-El-Khalick, 2014) as well as NOS pedagogy (Hanuscin et al., 2011). A variety of contextual…

Understanding nature of science (NOS) is integral to the development of students' scientific literacy. While NOS studies are growing worldwide, none of these reported on the views of secondary school learners in the Philippines. Hence, this study examined the Filipino junior high school (JHS) students' views of the NOS and determined whether…

Erduran and Dagher's (2014) account of the Family Resemblance Approach (FRA) to Nature of Science (NOS) is a relatively new framework that frames NOS in a holistic fashion, inclusive of cognitive-epistemic and social-institutional aspects. This approach has also been referred to as the "Reconceptualized Family Resemblance Approach to Nature…

While the importance of explicit and reflective NOS instruction is clear in the literature, questions remain about how to enact such instruction. That is, literature is sometimes unclear in defining how to enact explicit and reflective NOS instruction. While some authors recommend using questions (e.g., Clough 2007) to enact effective NOS…

This study employed a case study methodology to investigate students' misconceptions about solid, liquid, and atmospheric pressure. The research included 36 8th-grade students from various middle schools in Giresun, comprising 19 girls and 17 boys. Data collection involved a test consisting of 14 concept cartoon questions, and the concept cartoons…

Understanding the nature of science (NOS) is an important goal of science education, and textbooks are a key factor in shaping students' conceptions of NOS. In this study, we analysed NOS represented in middle school chemistry textbooks in the Chinese mainland. The selected materials were three most commonly adopted textbook series, which were…

This study investigated the added value of real-time adaptive feedback on seventh graders' performances in tablet-based geometry learning. To isolate the effects of the medium (ie, tablet) from those of the feedback, three groups were compared: paper-and-pencil, pen-based tablet without feedback and pen-based tablet with feedback. The feedback was…
