Previous studies have demonstrated that the socio-scientific issue approach (SIA) and design thinking (DT) can inspire creative thinking in science learning. However, the way in which the integration of SIA and DT fosters creative thinking in entrepreneurship (CTE) among rural secondary school students during science learning remains unclear. To…

The underrepresentation of women in science, technology, engineering, and mathematics (STEM) fields limits their development, their career opportunities, and societal progress. This study used social cognitive career theory to explore the relationship between informal STEM learning activities and STEM career intention in female high-school…

Epigenetics shows how environmental factors and life experiences alter gene activity without changing the gene sequences. This review examines key epigenetic mechanisms such as DNA methylation, histone modifications, microRNAs, and long non-coding RNAs, and their roles in gene regulation. It also highlights the impact of maternal diet, stress, and…

We outline the basic theory behind white light interferometry and the workings of a typical light interferometer microscope. We study WLI images obtained for rough and smooth chrome steel spheres to illustrate the principle that curved rough surfaces can be imaged with such a device as long as the surface roughness is kept within certain limits.

We present a simple and affordable method for making a surface electrodynamic trap for microparticles. The principles of electrodynamic trapping of charged particles are discussed and step-by-step instructions on how to make a surface trap are given. In addition to the electrodynamic trap implementation and operation process, options for its…

Learning progressions (LPs) serve as frameworks for understanding the level of complexity of students' ideas within a domain. Multifaceted LPs contain multiple interrelated constructs where increased knowledge in one construct may increase knowledge of a separate construct. While it is challenging to identify and test these contingencies between…

In this article, we demonstrate the use of a simple pendulum to explore the concepts of kinematics and dynamics. A simple homemade pendulum and a phone-based accelerometer are used to determine, at various points in time, the acceleration of a moving train. The dynamical and kinematics data from the homemade pendulum and the accelerator can then…

The distinction between pressure in a liquid and in a gas is often treated in a cursory way, or not treated at all, even in university level textbooks. Most texts fail to point out the relation between pressure and density in a gas as compared to pressure in a--virtually incompressible--liquid. In many instances this also results in a dismissive…

Content and accuracy evaluation of textbooks is important as it provides quality assurance to both teachers and learners, especially in the new normal where modular instruction is used. This research aimed at evaluating the biology textbooks used by Senior High School STEM Science teachers (n=15) in content, presentation, and learning strategies.…

This article considers science teaching and learning as may be understood through the integration of indigenous artefacts into physics curriculum in Zimbabwean schools. It comments significance of and elaborates on the issues raised in Nadaraj Govender and Edson Mudzamiri's paper entitled: Incorporating indigenous artefacts in developing an…

The science curriculum aims to provide students with the identity of a researcher, thinking skills, and scientific process skills. Critical thinking skill emerges as one of the skills that should be emphasized in the teaching process in terms of its structural features and the qualities aimed to be given to individuals. For individuals to gain…

Global climate change (GCC) presents unprecedented global concerns, notably food supply limitations, unsustainable use of natural resources, and widespread environmental degradation. The International Panel on Climate Change (IPCC) reports a 0.85 °C increase in global average temperatures between 1880 and 2018 and a 50% increase in global carbon…

The excess of curriculum content is a well-known problem in high school biology. Some strategies to adjust the amount of content to the available classroom time have been proposed, but none has been widely accepted and applied. Furthermore, biology is frequently presented in high school not as an integrated science, but as a collection of…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…
