With the better understanding of human genome and genetic contributions to human complex diseases, more and more clinical genetic tests have been developed for the prevention, diagnosis, and treatment of human diseases. This has raised new challenges to classroom teaching of medical genetics (MG) in medical education of undergraduates, who are…

Effective science instruction in a blended learning approach is synonymous with the strategic use of instructional videos (IVs) to fill the gap in teacher support. This study aims to determine the IVs' effectiveness in improving students' concept retention and overall learning experiences. The experimental group was exposed to instruction…

Virtual classrooms based on the metaverse or virtual reality are useful and effective for imparting basic chemistry concepts. Interactive and immersive environments can effectively teach fundamental chemistry concepts, such as chemical bonding and formulas, thereby making these otherwise abstract and intangible ideas more accessible and…

[superscript 1]H NMR spectroscopy is a molecular characterization technique that is ubiquitously used in research and teaching laboratories alike. Strategic deuteration of molecules is a commonly employed technique in the deconvolution of [superscript 1]H NMR signals. Here this approach is applied in a second-year chemistry course in which…

In this study, firstly, university biology students' conceptual understanding and potential misconceptions concerning meiosis were studied. Secondly, an easily applicable drawing task was used to foster students' metaconceptual awareness which would help them to reach conceptual change. A quasi-experimental design with a non-equivalent control…

General Chemistry is a course where students are expected to nurture the development of their fundamental concepts in chemistry. Students begin general chemistry with alternative conceptions about the topics and fragmented knowledge structures. Majority of students who successfully complete the general chemistry course sequence continue to hold…

A qualitative pre-/post-test case study was conducted to explore the influence of inquiry-based education in eliciting learners' understanding of the particulate nature of matter in the gaseous phase. Two grade four classes (n=116) were conveniently and purposively sampled from two farm schools in Pretoria, South Africa. Data was collected through…

The Human Orrery is a representation of the Solar System at a human scale, on which positions of planets over time are symbolized by different discs. Learners can then walk along the orbits of the planets with the right pace. This pedagogical tool uses the principles of enacted cognition to promote a better understanding of the scientific laws of…

The study determined the effect of instructional scaffolding strategy on senior secondary school Biology Students' academic achievement and retention of concepts. Two research questions and two hypotheses were formulated for the study. Quasi-experimental research design involving pre-test, the post-test control group was employed. The population…

We have investigated the efficacy of on-line, multimedia learning modules (MLMs) as preparation for in-class, lecture-based tutorials in electromagnetism in a physics course for natural science majors (biology and marine science). Specifically, we report the results of a multiple-group pre/post-test research design comparing two groups receiving…

Passive, lecture-based forms of instruction are often ineffective in helping students develop deep conceptual understanding of scientific concepts. Student-centered forms of instruction based in a constructivist framework, where students are guided toward actively constructing their understanding, have been met with greater success. However,…

Interactive-engagement (IE) techniques consistently enhance conceptual learning gains relative to traditional-lecture courses, but attitudinal gains typically emerge only in small, inquiry-based curricula. The current study evaluated whether a "scalable IE" curriculum--a curriculum used in a large course (~130 students per section) and…

Previous research suggests that students; prior knowledge can interfere with how they observe and remember lecture demonstrations. We measured students' prior knowledge in introductory mechanics and electricity and magnetism at two large universities. Students were then asked to predict the outcome of lecture demonstrations. We compare…

As has been shown by previous research, students may possess various misconceptions in the area of thermal physics. In order to help them overcome misconceptions observed prior to instruction, we implemented a one-hour lecture-based intervention in their introductory thermal physics course. The intervention was held after the conventional lectures…

This study investigates the effects of using interactive computer animations based on predict-observe-explain (POE) as a presentation tool on primary school students' understanding of the static electricity concepts. A quasi-experimental pre-test/post-test control group design was utilized in this study. The experiment group consisted of 30…
