[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] We discuss the theoretical underpinnings that informed the considerations and decisions that shaped the design of a curriculum unit entitled "Electromagnetic radiation--principles, applications, and decisions". This unit is part (45 h) of the…

Recent reforms have introduced integrated science, technology, engineering, and math education (STEM) that has highlighted an interdisciplinary approach to train students as better problem solvers. In addition to STEM disciplines, art, language, and other disciplines integration are also stressed (STEM+). In this paper, a STEM+ (STEM + art +…

A descriptive, mixed methods study investigated learning outcomes and processes of integrating environmental education (EE) and science education (SE). Specifically, this study examined the impact of EE-based constructivist science teaching approach on students' science achievement scores, environmental self-efficacy, course completion rate, and…

Vaping (the use of an e-cigarette) is a common practice among teenagers; 26.7% of high school students report vaping in the last 30 days (Johnston, Miech, O'Malley, Bachman, Schulenberg, and Patrick 2019), making this issue highly relevant. In order to make an informed decision about the use of e-cigarettes, students need to understand the impacts…

Apart from classroom presentations to their instructors and peer groups, STEM students have limited opportunities or encouragement to engage in guided communication of scientific concepts to others (family, friends, or the general public). A critical need exists for accurate, comprehensible science to be disseminated to these groups. To develop…

Science learning video integrated with local potentials was developed and tested to improve students' science process skills (SPS) and concept mastery. The learning video was developed for the topic of micro-hydro power (MHP) plant. This study was aimed to determine the effectiveness of the video integrated with the local potential of MHP plant in…

The use of technology is increasing rapidly in our society, and classroom teachers must recognize the impact and importance of technology in the lives of their students. It is crucial that college faculty involved in teacher training design courses that integrate mobile technologies to prepare the next generation of teachers. In this study, we…

Today, science education demands preparation of scientifically literate people, emphasizing more the process of working with information than owning it. Such a task requires a deep understanding of pedagogical content knowledge by science teachers. This study focuses on revealing the beliefs of prospective chemistry teachers during their teaching…

"Minecraft" is a computer game that allows players to move around in a virtual world, building almost limitless creations with a vast array of cubic blocks with varying textures and properties. Its representative settings and processes link to the real world, making the game a valuable tool for both presenting scientific concepts to…

This research aimed to evaluate the students' conceptual understanding and to diagnose the students' preconceptions in elaborating the particle characteristics of matter by development of diagnostic instrument as well as Rasch model response pattern analysis approach. Data were acquired by 25 multiple-choice written test items distributed to 987…

Introduction: The emerging technology of three-dimensional (3D) printing has the potential to provide unique 3D modeling to support specific content in science, technology, engineering, and mathematics (STEM) education, particularly chemistry. Method: Seventeen (n=17) students with visual impairments were provided direct instruction on chemistry…

A qualitative pre-/post-test case study was conducted to explore the influence of inquiry-based education in eliciting learners' understanding of the particulate nature of matter in the gaseous phase. Two grade four classes (n=116) were conveniently and purposively sampled from two farm schools in Pretoria, South Africa. Data was collected through…

Conceptual change theories assume that knowledge structures grow during the learning process but also get reorganized. Yet, this reorganization process itself is hard to examine. By using concept maps, we examined the changes in students' knowledge structures and linked it to conceptual change theory. In a longitudinal study, thirty high-achieving…

In this research, the teaching of mechanical waves was realized with inquiry-based learning; the aim was to determine the changes in students' conceptual understanding of spring, water, and sound waves. It was designed as action research. The study group comprised 58 upper-secondary school students enrolled in 10th grade at an Anatolian…

Green Tycoon is a free-of-charge game-based mobile application that embraces a systems thinking approach to introducing students to a biorefining process model within green chemistry. Players adopt the role of a manager in a chemical factory, synthesizing the fictional compound, Yorkanone. Through upgrading the system and engaging with the…
