Understanding the photosynthesis concepts is challenging due to its abstract nature, often leading to student misconceptions. This study aims to identify and analyze misconceptions among science and social studies students using the image analysis method. A total of 78 students (32 science, 46 social studies) participated, selected through a…

The aim of this study is to define epigenetic literacy and describe how it can be included in school biology. Epigenetics is a new field of research in biology with abundant societal consequences and conceptual implications on how genetics is understood. Epigenetics explains how genes are regulated, thereby clarifying cell differentiation, and…

This study provides insights into the use of metaphors in protein synthesis descriptions in upper secondary chemistry and biology textbooks. Data were collected from seven Swedish textbooks and analyzed with the Metaphor Identification Protocol and categorized within the framework of Conceptual Metaphor Theory. The results reveal two main parallel…

Virtual simulations are a very useful educational resource to improve the teaching of chemistry. Their use makes it possible to facilitate the comprehension of concepts, promotes the development of scientific competences and even improves student attitudes toward chemistry. However, it is important to point out that a simulation by itself is not…

Especially since the COVID-19 pandemic when teachers might have found or created videos for students to watch, flipped classroom methodology has interested many secondary-level chemistry teachers. However, as the secondary coauthor teachers here found, most of the research on the effectiveness of flipped classroom methodology has been performed at…

This study explored the use of an innovative instructional approach called Productive Failure (PF) to design an educational game and its support. The study then examined the effects of two different types of instruction--PF vs. Direct Instruction (DI)--on learning genetics and relevant mathematical knowledge in a Game-Based Learning (GBL)…

Quantum science is in the news daily and engages students' interest and curiosity. A fundamental quantum science concept that underpins medical imaging, quantum computing and many future technologies is quantum spin. Quantum spin can explain many physical phenomena that are in the lower secondary school curriculum, such as magnetism and light,…

The French natural philosopher Henri Victor Regnault (1810-1878) was one of many researchers who contributed to the development of the thermometer in the 19th century. In this paper, we use an example from Regnault's work to explore how the history of thermometry can provide a context for teaching upper-secondary chemistry students about the…

Modern, student-oriented teaching can be characterized by the promotion of autonomy and interest. In the school subject of biology, it is necessary to focus on different ecosystems from different aspects. One ecosystem that has hardly been considered in biology didactics so far is the UNESCO World Heritage Wadden Sea. Therefore, this study…

We present a new secondary school teaching method of quantum uncertainties of two-state systems. Intending to be a material teachable in schools, only two-state systems described by real numbers can be considered. An elementary argumentation based on school statistics leads to the identification of the uncertainty of a physical quantity in such…

Why does a raindrop on a window pane show an image of the environment that is turned upside-down? And why does vision go blurry underwater, but is perfectly clear with diving goggles? Our everyday life is rich in optical phenomena. Unfortunately, these phenomena often play a subordinate role in Optics teaching, compared to ray constructions or…

While the distinction between academic disciplines and school subjects has received some attention, the question of which subject matter content knowledge (CK) teachers need as a foundation for initial teacher development has been raised. In science education, Teacher-related Science Content Knowledge (TerSCK) has been conceptualized to model the…

This study investigates the role of environmental insight--defined as students' prior knowledge--and the use of a virtual reality laboratory in exploring celestial bodies and solar system content integrated with Qur'anic science, with a focus on their effects on students' argumentation abilities. The research employs a quasi-experimental design,…

To make sense of our interconnected and algorithm driven world, students increasingly need proficiency with computational thinking (CT), systems thinking (ST), and computational modeling. One aspect of computational modeling that can support students with CT, ST, and modeling is testing and debugging. Testing and debugging enables students to…

Representations constitute an important part of chemistry knowledge. This paper revisits the notion of the term, symbolic, in the chemistry triangle proposed by Johnstone using the theoretical lens of social semiotics. In doing so, this paper proposes a framework of chemistry learning that highlights representational re-description and…
