Electromagnetic (EM) waves are indispensable in modern telecommunications. Despite their essential role in modern technology, EM waves are considered to be an abstract concept by many students. In this activity, an inexpensive two-coil system was constructed in a teaching laboratory and used to demonstrate information transfer by non-sinusoidal EM…

This study aimed to elucidate the perceptions and mental models of 5th-grade secondary school pupils about shadows, solar eclipses and lunar eclipses through drawings. A total of 443 pupils studying at public schools in Afyonkarahisar participated in the study. It was conducted as a case study, one of the qualitative research designs. As a data…

This study was aimed to calculate teachers' effective use of time in scientific inquiry lessons. The research was designed as a case study. The study group of the research consists of 5 pre-school teachers determined by the convenient sampling method. Before the study, the participants were taken in-service training program on scientific inquiry.…

Based on the pedagogical principle of cognitive conflict, Inquiry-Based Laboratory Activities (IBLAs) have been shown to improve conceptual understanding of challenging science and engineering topics. Yet, providing students physical apparatuses to complete an IBLA is not tenable in every instructional setting. This paper reports design,…

This study aims to draw attention to data literacy, which is considered an important skill of the 21st century, and to provide an example activity that would incorporate it into chemistry education. The activity was designed using real data of Robert Boyle's experiment. The activity aims to examine Boyle's data in such a way to support data…

Case studies are helpful teaching tools that can bring scientific concepts to life. Here, we present a case study related to protein-ligand interactions, amino acids, protein structure, and protein modification. While protein-ligand interaction is a foundational concept within Biochemistry, there are few available case studies that focus on this…

The declining interest in STEM careers in the United Kingdom has raised concerns, prompting this study to explore the intricate relationship between social, cultural, and scientific identities and their impact on students' inclination towards science and technology career pathways. Additionally, the study examines the associations between gender,…

This project engaged Ghanaian secondary pupils in authentic science and engineering activities by using model biodigesters that reduce organic waste and produce biogas and fertiliser. The pupils' activities paralleled scientists' activities, such as asking research questions and designing experiments. Our study included two cohorts of Ghanaian…

The forest school approach to nature learning has gathered momentum in the UK and across parts of Europe including Scandinavia for well over 50 years. In other contexts that include Canada, China, New Zealand and Australia, nature-based early childhood education and care settings, influenced by European forest school approaches, are in a rapid…

The ubiquitous bouncy ball, or "superball," is an engaging child's toy that has endured for more than 50 years. But what makes a bouncy ball so uniquely suited to its name? Steel balls, for example, are more highly elastic than are butadiene bouncy balls. Yet it is butadiene balls, and not steel balls, that appear in toy stores and…

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…

The purpose of "practical work" in chemistry lessons as perceived by teachers varies and does not always correspond with an emphasis on procedural learning. Teachers project various objectives in them. These activities have various characteristics and potential. The goal of this study is to find out the set of characteristics of…

Space science education is an area of emerging importance in the 21st Century. Missions sponsored by the U.S. National Aeronautics and Space Administration (NASA) and programs facilitated through the NASA Space Science Education Consortium (NSSEC) offer unique opportunities to foster learner interest in space science as well as the broader field…

The present study examines the exemplification practices of a university biology instructor during a semester-long course. Attention is given specifically to how the instructor approaches "memorable exemplification"--classroom episodes identified by students as a source of memorable learning experiences. A mixed-method research approach…

Light is a topic that is often taught in year 3 (ages 7-8) in English schools, where children learn that light is needed for us to see, that it can be reflected from shiny surfaces and that shadows form when light is blocked by an object. They may also have some experience of how the size of shadows changes when the distance between a light source…
