In this article, we propose a simple and accessible model of a magnetic levitator fitted with a Hall sensor. This model also allows to determine the magnitude of the magnetic field within the levitator working volume. Students can also compare the experimental magnetic field values to reference values in magnetism textbooks. This Arduino-based…

This study was conducted with a student who is visually impaired and questioned the force of gravity. The different stages encountered in the process were specified as steps in the study and it was shared what kind of inquiry form was needed at each step. There are different activities such as waiting for a week and thought experiment in the…

A simple inquiry-based activity called "Fruit Puzzle" was designed to investigate high school students' understanding of the relationship between the concepts of density and solution concentration at a submicroscopic level. The first activity allowed students to predict whether five types of fruit would sink or float in water and asked…

The demand for improving student interest in science has increased efforts toward teaching Einstein's theory of general relativity in schools. Research has already shown that teaching Einsteinian gravity at the secondary level is feasible, however, appropriate resources must be readily available for science teachers to make Einsteinian gravity…

This article first put forward the educational application of immersive virtual laboratories for the problems of poor spatial thinking ability and weak hands-on operation ability. Second, aiming at the problems of a lack of excellent backbone teachers and insufficient educational information equipment, a Tibetan-Chinese bilingual immersion virtual…

We present an integrative mixed-methods systematic review of research on laboratory work in secondary-school science education from 1996 to 2019. The aim of the study is to identify important aspects of how to successfully make use of laboratory work as a science-teaching strategy in secondary schools. By engaging teachers, our study uses a…

Many high school students learn about nutrient cycling during biology, environmental science, and agriculture classes. These lessons often focus on soil and plants, and nutrient cycling is usually taught independently from climate change. Scientists know that animals, including fish, can have strong effects on nutrient cycling (i.e., nitrogen and…

This study investigates the effectiveness of using a REACT strategy instruction enriched with guided inquiry-based experiments to improve 7th-grade students' understanding of mixtures compared to conventional teacher-centered instruction. A convergent parallel mixed-method design was used, and 39 middle school students were divided into…

As e-commerce increases, the demand for packaging materials and the potential for generating waste and negative environmental impacts also rise. Packing peanuts are a type of plastic packaging material that are used to protect goods during the shipping process. Petroleum-based plastics are common packaging materials due to their low cost, light…

Hands-on learning is a staple in high school science education, as it provides students with a fast-learning curve and a great degree of field competency. However, due to the safety risks associated with high school students in university chemistry laboratory settings, high school students rarely engage in authentic hands-on chemical learning. To…

An inquiry-based laboratory learning unit was designed to enhance high school students' understanding of the application of lipase as a catalyst to synthesize isoamyl and geranyl ester derivatives as well as to promote their understanding and positive perceptions of green chemistry. The learning unit consisted of three laboratories and a final…

Floating and sinking (FS) is a key topic in science education, both at primary and secondary levels. The interpretation of FS phenomena, however, is challenging due to the difficulty of the scientific concepts and explanatory models involved (e.g., density, buoyancy), along with students' everyday experiences, which conflict with scientific…

The implementation of video modeling examples of mathematical hands-on experimentation may provide students with authentic and, at the same time, not too cognitively overwhelming experiences. However, the effectiveness of video modeling examples can be influenced by different characteristics of the observed models. On the one hand, based on the…

Fungi mostly reproduce through spores that are adapted for airborne dispersal; hence, fungal spores (and fungi) are found virtually everywhere. Fungi can be "friends or foes." Our friends include fungi used in the food and biotech industries, fungi that contribute to the cycling of carbon and nutrients, and those involved in the…

Hands-on experiments and teacher-based demonstrations are two standard teaching methods in secondary school when teaching chemistry in the laboratory. The available literature on these two teaching methods focuses on students' academic achievement. Most of this literature reports inconsistent results, and few studies examined teachers' and…
