Research has shown that teachers and students have difficulties in connecting climate change evidence with climate change claims. Such difficulties may come from the lack of knowledge about how scientific models and modeling work in climate science. Climate change as a complex system with a large time and land scale requires sophisticated…

The teaching and learning of quantum physics has recently become a topic of increasing interest in physics education research. In particular, the study of two-state systems is gaining importance as a means of teaching quantum physics at various educational levels. Meanwhile, a number of approaches have been developed that are also suitable for…

This study aimed to examine the effect of three teaching approaches: The traditional teaching method, Teacher based demonstration experiment (TBDE), and the Student hands-on experiment (SHE), on students' conceptual understanding of solutions and titration. The data were collected using a chemistry achievement test (CAT) comprising of 30…

Digital practical work (DPW) has emerged as a highly effective and indispensable component of science education, enhancing and extending traditional laboratory experiences. DPW aims to complement physical laboratory experiments, particularly those that teachers may find challenging to conduct or lack the confidence to perform. In this study, a…

Virtual laboratories and simulations have emerged as innovative solutions for science teaching. However, existing resources have various limitations and constraints including cognitive load/mental burden and limited coverage of all necessary steps in scientific inquiry, focusing mainly on the experimental simulation. To bridge this gap and address…

The study investigated the potency of ethnoscience instruction on the critical thinking ability of biology students. The study employed a quasi-experimental research design, with a total of 113 senior secondary school two (the equivalent of grade 11) students from two schools in educational district V of Lagos State, Nigeria. All students in the…

Leaders, policymakers, and researchers have called attention to the need to improve critical aspects of physics programs, from teaching and pedagogy to making physics more diverse and equitable. As such programmatic changes are challenging and require a second-order change to be effective, many physics faculty responsible for carrying them out are…

Heavy content, high volume courses commonly create challenges for undergraduate students. Two such courses at our university are the introductory semesters of anatomy and physiology for first-year nursing students, taught by biology instructors. Despite the vast literature indicating the efficacy of using concept maps as a tool for learning, it is…

Background: Studies in biology have shown that students perceive variation and evolution to be difficult areas to learn. This has sparked rote learning of variation and evolution concepts and is evidenced in poor performance in tests involving these concepts. Purpose: In light of the significant role of variation and evolution in a human's…

With the rapidly increasing demand for STEM skills, many scientists, mathematicians, engineers, and technology professionals encourage students to pursue STEM careers. However, communicating science to lay audiences is challenging due to complex scientific terminology. This qualitative research aimed to demonstrate how an exemplary scientist, Dr.…

This communication reports the curriculum changes and how they worked when an upper-level experimental physical chemistry course had to switch from face-to-face to online teaching within a matter of days. Although several of the learning goals of the laboratory-based course could still be met in the online environment, others required…

There are multiple ways to put science into a case. This column provides original articles on innovations in case study teaching, assessment of the method, as well as case studies with teaching notes. This month's issue discusses different ways of presenting science in case studies.

This article critically explores the epistemic "practices" of bioscience, using creative writing and analyses of science studies to implicate the non-linguistic side of science where a "feeling for the organism" matters more, perhaps, than theoretical precision. It offers new critique of curricula in science which are so…

The oscillating atmospheric CO[subscript 2] concentrations at Mauna Loa, on the island of Hawaii, Hawaii, United States of America, are Fourier transformed in order to extract the period of oscillations. Also well-known as the Keeling curve, CO[subscript 2] concentrations (in time series) at Mauna Loa oscillate in direct association with seasonal…

The push for project-based learning (PBL) has been at the forefront of education for the last decade. Exposure to projects even in the lower grade levels helps students learn foundational skills that will strengthen the collaborative and leadership skills that will assist them as they get older. The result of a typical PBL project requires…
