The past [approximately]15 years have seen increasing interest in defining disciplinary core concepts. Within the field of physiology, Michael, McFarland, Modell, and colleagues have published studies that defined physiology core concepts and have elaborated many of these as detailed conceptual frameworks. With such helpful definitions now in…

This article will (1) initially outline first-year nursing and undergraduate exercise sciences student perspectives on examinations of the 2011 Michael-McFarland (M-M2011) core principles in physiology through an anonymous online survey, and (2) model an updated approach based on these qualitative findings. Briefly, for the first perspective (i of…

An immense body of literature on astronomy studies has provided evidence that individuals perceive the lunar phases concept as difficult. Furthermore, many studies have shown erroneous explanations or alternative conceptions of lunar phases. However, there is also a need to understand how individuals construct an explanation of the Moon's phases.…

Learning about evolution can be challenging for students, as a full understanding may require them to see the world in new ways, to master a disciplinary language and to understand complex processes. Drawing on a long line of theoretically grounded arguments of philosophers and researchers for including wonder in science teaching, we report on the…

The Online Periodic Table of Elements (Ptable) is a Wikipedia-linked periodic table that displays a list of chemical elements organized by atomic number, electronic configuration, and recurring chemical properties. Elements are listed in reading order, increasing in atomic number, in their most basic form. The current study seeks to assess the…

Some research works have showed that Ghanaian teachers, teaching chemistry in the senior high school, have conceptual difficulties in organic chemistry. This research explored the factors contributing to teacher's conceptual difficulties on teaching organic chemistry to high school students. Through explanatory sequential mixed methods design…

One of the ways to acquire scientific knowledge is by reading science comics. This study aims to investigate the attitudes (e.g., reading habits, interest, motivation) of university students toward reading science comics, and how they read science comics for acquiring scientific knowledge reflected by an eye tracker. Sixty-five undergraduates were…

This integrated STEM activity on the design of a vertical farming system has biology as the lead discipline and relates to the concept of photosynthesis. Students investigated the optimal design of vertical farms that will deliver appropriate amounts of water, sunlight and carbon dioxide to plants such that there will be optimal yield. Through…

The aim of this study is to reveal the effect of the flipped learning model used in the laboratory practices course of pre-service teachers on their conceptual understanding and to evaluate their opinions about this model. In order to achieve this aim, science teaching laboratory applications course was conducted with the flipped learning model…

This study examined the effects of using a combination two novel technologies on the development of knowledge and understanding of ecological science concepts for a small of preservice primary teachers, who had self-identified as having low prior background knowledge in science concepts and low confidence in their abilities in teaching science.…

The primary objective of this research was to investigate the effects of model-based science instruction on the conceptual development of 7th grade students in the topic of electricity. This qualitative research was conducted during the 2022-2023 academic year, using purposive sampling method. The study comprised 33 7th grade students (18 boys and…

Cosmology presents students with ideas that stimulate their curiosity and brings together various concepts from STEM that call on a variety of reasoning types across multiple representational modes, involving subtleties of spacetime relations, a variety of models and evidence requiring multiple lines of high precision observations. This study…

The main purpose of this study was to describe the development and use of a flowchart for preservice chemistry teachers' problem solving on the First Law of Thermodynamics. Twenty-seven undergraduate preservice chemistry teachers attending a Physical Chemistry course participated in this study. The responses of the participants to the set of test…

Acid-base chemistry, and in particular the Lewis acid-base model, is foundational to understanding mechanistic ideas. This is due to the similarity in language chemists use to describe Lewis acid-base reactions and nucleophile-electrophile interactions. The development of artificial intelligence and machine learning technologies has led to the…

A problem-based learning activity focusing on the human impact on the environment and the importance of sustainable development is presented. The activity revolves around a mysterious island where the civilization is on the blink of extinction, prompting students to investigate how human behavior, ecosystems, resources, and natural balance…
