Argumentation is central to science learning. Students in every domain of science should have the opportunity to develop the ability to think and act in ways associated with argumentation. When engaged in argumentation, students learn how to puzzle through problems, to see multiple ways of finding solutions, to gather and evaluate evidence on…

One of the main objectives of science education is to produce students and, in general, a society that is scientifically literate. To achieve this objective, teachers across the different educational stages must work on science at school, so it is essential that students in education degrees reach scientific competence, but for this, it would be…

Information and communication technology (ICT) competences are among the most important requirements to effectively teach mathematics and science in today's classrooms. Teacher educators in the Southern African Development Community (SADC) region have prioritised ICT competences for pre-service teachers (PSTs) to effectively select suitable…

Although there is a lot of interest in the development of computational thinking (CT) and the benefits it could have for every student, integrating it into science classrooms may be more difficult than traditional teaching. This can be very challenging for South African science teachers. Thus, there is an increasing need to prepare teachers and…

It is of great importance to examine the level of science teaching self-efficacy (SE), which is related to technological developments in primary school teacher education. It is seen that this subject is not addressed in the context of technological pedagogical content knowledge (TPCK) and visual metaphors. The purpose of this research was to…

Physics II is an undergraduate course on basic electromagnetism that I teach for engineers, and it includes topics from optics as a natural application. Among the many challenges of conducting video lectures during the local restrictions of the SARS-CoV-2 epidemic was finding demonstration material. In this article, I describe how these…

In this work, we will describe a Peer Project Learning assignment focused on the STEM project-based learning activities where students build a custom board game with a series of constraints that guide them to learn (and later teach) about the main concepts of an electromagnetism physics course for undergraduate students.

Basic science courses, such as physics, are fundamental to precollege studies. For instance, in different engineering applications, electricity and magnetism require comprehending subjects such as electrical circuits and power electronics. However, abstract concepts such as electric or magnetic fields are often difficult to explain without visual…

The oscillations of one mass "m" suspended between two different springs, assuming a friction force proportional to the velocity [minuscule], have been studied. For this purpose, an assembly for this system has been made. The movement of the mass is recorded with a smartphone and analysed with "Tracker." It is obtained that the…

Enzymes are organic molecules known for their catalytic nature because they accelerate metabolic reactions in organisms. The study of enzyme functions and modes of action is essential to understand Biochemistry. This study aimed to analyse the acetylcholinesterase enzymatic activity, as well as the enzymatic inhibition mechanism in practical…

The purpose of this study is to examine changes in pre-service science teachers' entrepreneurship mindsets during engineering design-based activities. A holistic single-case study was used in the study. Twenty-eight pre-service teachers carried out engineering design-based activities (five weeks, 20 hours) in the science teaching laboratory…

The shift to student engagement in scientific and engineering practices to learn science provides opportunities for science learning and language learning to occur in tandem. These opportunities also pose new challenges for elementary pre-service teachers (PSTs) since literacy methods courses have been presented separately from science methods…

Background: Self-efficacy in the use of ICT refers to a person's belief in their ability to succeed in the use of ICT in the teaching, learning and assessment process as well as research purposes. Purpose: The incorporation of ICT into teaching, learning and assessment, and for research purposes is a powerful tool that promotes the…

The properties and functions of complex systems apply across a variety of domains of science and are at the heart of the solutions to many global crises facing the world today. As such, understanding of complex systems has been increasingly recognized as a core goal of science education. Learning about complexity-related concepts and phenomena is…

To stimulate the intellectual curiosity of elementary school students, we conducted a workshop in distance education aimed at exploring the microscopic world inside a cell. In this workshop, elementary school students motivated to learn more on the subject of science analyzed movies of the Brownian motion of micrometer-sized particles suspended in…
