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…

In this laboratory experiment, a guided inquiry exploring the physicochemical principles of the dissolution of Ca(OH)[subscript 2](s) in water is proposed for laboratory classes in university and high school. As part of students' inquiry, two experimental approaches are used. One is the change in solubility with temperature revealed by measuring…

Experiments serve different purposes in chemistry education ranging from illustrating a certain subject matter to providing data for school-based research projects. When students use these experiments to collect data and draw conclusions, it is important that these experiments are valid. In this study, a new experiment for the determination of the…

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…

A solenoid is a coil wound many times on a cylinder of length greater than its diameter. Solenoids are mainly used as electromagnets, because a magnetic field is formed when current flows through a solenoid. The solenoid described in secondary school and university textbooks is a single-layered solenoid. Further, textbooks and papers focusing on…

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…

Fish pekasam is a traditional fish fermentation product that can be used in biotechnology learning through the Project-Based Learning (PjBL) model. However, the use of PjBL by teachers remains low due to difficulties in developing learning instruments. This study aimet to develop PjBL learning instruments for making fish pekasam, reflecting local…

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,…

Artificial intelligence (AI) is now a major driver of societal acceleration making a significant impact on science and science education. AI is used by scientists to generate hypotheses, design experiments, collect and interpret data in ways that were not previously possible with traditional methods alone. Science education research is…

This study examines the impact of the Scientific Creativity in Practice program on students' scientific creativity. This comprehensive teaching program aims to foster general creative skills, domain-specific competencies, and certain personality traits in science education. The program includes a variety of interventions and reflection tools that…

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…

In this paper, a self-created analogy is presented based on comparing the process of osmosis with a situation recreated in a train carriage. It was implemented with upper-secondary education students at a secondary school in Chiclana de la Frontera (Cádiz, Spain). To assess the progression of the students' models on osmosis, their activities…

Based on the control-value theory, we investigated the achievement emotions experienced in science and mathematics classes by high school students in the context of digital technology use for educational purposes. Specifically, we examined the mediating role of cognitive appraisals of control and value in the relationship between students' digital…

Background: Argumentation, the justification of claims with reasons and/or evidence, has emerged as a significant goal in science education in recent years. Yet, there is limited understanding of secondary students' arguments and particularly their use of warrants in interdisciplinary contexts such as science and religious education. Furthermore,…

The number of studies analyzing chemistry textbooks has steadily increased over the years and has notably surged in the past decade. In this literature review, we examine the research literature on chemistry textbooks. The review spans 40 years of research (from 1981 to 2021) and includes 79 studies published in over 20 different journals,…
