Ray diagrams are widely used in introductory physics textbooks to illustrate the behavior of ideal systems of lenses or mirrors in geometrical optics. Their virtue lies in their explicit display of multiple ray paths connecting object and image points, which leads naturally to an understanding of how a planar object is transformed into a planar…

It is well known that when two waves are added they produce beats. These beats are the amplitude modulation of the initial waves and occur periodically at a rate equal to the frequency difference of the two waves. Acoustical beats arise from sound waves of nearly equal frequencies. Optical beats arise from the interference of two light waves of…

Learning scientists often use Donald Stokes's influential characterization of the relation between basic and applied research in his book "Pasteur's Quadrant" to suggest that most of the work in the learning sciences lies, or should lie, at the intersection of both types of research, that is, in the cell that is epitomized by Pasteur's…

Work, kinetic energy (KE), and potential energy (PE) are key physics concepts, taught in essentially every introductory physics course along with the physical laws such as the work-kinetic energy theorem and the conservation of mechanical energy, which describe how the values of those quantities change during various processes. Quite appropriately…

This article presents an empirical study of the use of Indigenous knowledge of the "Bulan" kite to teach the concept of "equilibrium" among Muslim students (n = 109 students) in private Islamic schools (in the southern part of Thailand). The design of the culturally responsive teaching comprising three lessons was guided by the…

Raspberry Pi Pico, based on chip RP2040, is an easy-to-use development microcontroller board that can provide flexible input/output functions and meets the teaching needs of basic electronics to first-year university undergraduates. This article presents our blended laboratory design using Raspberry Pi Pico for the course unit Digital Circuits and…

Many students majoring in biology education at university find genetics as a quite complicated and difficult subject. A reflective journal has been used widely in teacher education to improve students' performance. This study aims to describe the role of the reflective journals for biology education students ina genetics course. The subjects in…

Two generative approaches to reaction mechanism instruction for novice students were compared to lecture instruction. In both approaches, students were coached to propose selected reaction mechanisms based on prior knowledge. New instructional methods were correlated with increased skill in representations of electron movements and other gains.…

Purpose: To align with the artificial intelligence and robotics (AIR) research and policy agenda, this paper puts forth an adapted five big ideas framework specifically tailored to teaching young children about artificial intelligence (AI) via robotics. Design/Approach/Methods: Grounded in early childhood education research, the proposed framework…

A STEM education program entitled "Come rain or shine" implemented in a primary rural school in southern Greece as part of the "Diffusion of STEM (DI-STEM)" project and the results of its implementation are presented in this paper. The educational program deepened in weather education and intended to develop eight scientific…

Mastering creative thinking skills (CTS) is crucial for enhancing students' science conceptual understanding. However, conventional teaching prioritizes linear thinking over the three sub-CTS essential to science learning: associative, visual, and divergent thinking. Weaknesses in these three sub-CTS cause students to have misconceptions,…

Intuitive conceptions based on cognitive biases (teleology, anthropomorphism, and essentialism) often prove helpful in everyday life while simultaneously being problematic in scientific contexts. Nonetheless, students often have intuitive conceptions of scientific topics such as evolution. As potential approaches to enable students to…

Although Machine Learning (ML) is found practically everywhere, few understand the technology behind it. This presents new challenges to extend computing education by including ML concepts in order to help students to understand its potential and limits and empowering them to become creators of intelligent solutions. Therefore, we developed an…

Science identity, encompassing perceptions of competence, interest, and recognition in science, alongside learning self-efficacy reflecting confidence to master science skills, are key drivers of outcomes. However, developmental patterns likely vary across contexts. Participants were 512 Chinese students spanning grades 1-3 who completed the…

Researchers engaging in science communication tend to present information that they find most important. However, understanding the level of prior knowledge and interest of a target audience is key for effective communication of science, especially when dealing with complex and mediatic themes, such as climate change. This study relies on a…
