As physics laboratory courses (labs) transition from traditional, model-verifying activities to discovery-based investigations, it becomes crucial to understand the role of the instructor in the implementation of various lab types. Prior work has started to address this need by examining either coarse-grained frequencies or fine-grained content of…

The nature of science (NOS) has been recognised as an essential component for engagement with socioscientific issues (SSI). However, the findings on the link between the two have been inconclusive. This calls for a shift from students merely knowing about NOS, to using their understanding of it as a tool for decision-making and participation in…

The undergraduates in the major of Environmental Science and Environmental Engineering frequently ignored the importance of identifying pollution sources for water environment monitoring and knew little about the techniques of identifying pollution sources. Thus, a laboratory experiment which focused on pollution sources identification in a water…

Comprehensive curricula are described for middle and high school classrooms built around the synthesis of biodegradable calcium alginate capsules prepared from food-safe chemicals. Experiments and activities question whether calcium alginate capsules are a viable alternative to single-use water bottles and consider what characteristics are…

High school students learn the basic voltaic and electrolytic cell concepts during their last year prior to entering an undergraduate teacher-education science degree. During the 4 years of university, students complete a sequence of topics designed to build on conceptual understanding presented in previous years. At the end of their degrees,…

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…

Pre-laboratory tasks are a best practice for preparing students for learning in the laboratory. Virtual labs, which use virtual reality to place students in an emulation of a physical laboratory where they have the capacity to manipulate equipment and materials as approximations of scientific practice, are emerging as an alternative to the…

Universal Design for Learning (UDL) provides a framework, based in brain research, to design instruction around the needs of all learners. By considering the UDL principles as educators design science instruction, they can proactively address how to engage students, how to make content accessible, and how to provide options for students to…

Climate change science is complex and perceived to be controversial in nature by some stakeholders. Yet from the perspective of educators and policy makers, climate change science is an important topic to be taught in secondary science education. The presence of controversy can influence teachers' instructional decisions and cause confusion about…

Hydrogen is a sustainable and climate-friendly storage for renewable energies and can directly be generated from sunlight, e.g., by photocatalytic water splitting. This article presents the photocatalytic hydrogen evolution using LED irradiation of an aqueous ZnS particle dispersion with Na[subscript 2]S and Na[subscript 2]SO[subscript 3] as…

The declining interest in science learning, along with students' perception that science is irrelevant to their daily lives, has been identified as a significant issue. This research aimed to help students connect abstract scientific concepts with their personal and everyday experiences. To achieve this, the research utilized the metaphysical…

The scientific community continues to give conflicting impressions about the contribution of laboratory activities to science learning and yet ignores the views of students who are the focus of learning. In this paper, we reviewed postsecondary school students' experiences in the science laboratories. Students were most concerned about the impact…

In order to fix some important concepts of Fundamental Physics, either because they are not usually discussed in depth in theoretical classes and much less at laboratories, or because they are not sufficiently developed in textbooks, it is more effective not to tackle them directly, but to propose a mental or practical experiment to attract the…

Electrification by rubbing different materials is a well-known phenomenon with a history that began more than five centuries B.C. ago. However, simple experiments can lead to contradictory or inconsistent results, and the history of this phenomena is plagued with non-intuitive results. For example, triboelectric charging by rubbing identical…

Instructional resources play an important role in conducting high quality education. This research assessed the availability and utilization of instructional resources in Moro Local Government Area (LGA) of Kwara State, Nigeria. Descriptive survey research was adopted for the study. A total of sixty (60) Biology teachers were randomly sampled from…
