Textbook anatomy depiction of the hepatobiliary tree is present in 55%-62% of the population. Misidentification of hepatobiliary variants can lead to bile duct injuries in cholecystectomies. A better understanding of variants has been cited as a key area for improvement in anatomy education. The aim of this study was to compare the effectiveness…

With the already widespread nature of multiple-choice assessments and the increasing popularity of answer-until-correct, it is important to have methods available for exploring the validity of these types of assessments as they are developed. This work analyzes a 20-question multiple choice assessment covering introductory undergraduate chemistry…

The multiple-choice section of the final examination for the first-year Advanced Physics I course at the University of Newcastle, Australia between 2010 and 2018 was investigated for gender bias. A Mantel-Haenszel analysis revealed that approximately 20% of the multiple-choice questions exhibited statistically significant gender bias. A schema for…

The use of multiple-choice (MC) instruments to assess pedagogical content knowledge (PCK) has advantages in terms of test economy and objectivity, but it also poses challenges, for example, in terms of adequately capturing the intended construct. To help address these challenges, we developed and evaluated a new instrument to assess science…

Resonance is a foundational organic chemistry concept, but it is consistently misunderstood by undergraduate students. The development of a concept inventory--a multiple-choice assessment where the incorrect answer choices stem from commonly held alternate conceptions--on the concept of resonance could help organic chemistry instructors quickly…

Complex subjects such as physiology can be challenging for students to learn. These challenges are not uncommon in implementing the learning process in physiology and affect learning outcomes. Dramatization is an interactive and effective method to improve learning outcomes. In a project designed by senior medical students, junior medical students…

Probing children's understanding of science concepts has been a focus of research in science education since the 1980s. In the process of learning, learners often produce many conceptions that differ from established scientific knowledge, which are commonly labelled as alternative conceptions (ACs). Knowing these ACs, their prevalence, nature,…

While formative assessment is a widely valued instructional approach to support meaningful learning, putting it into classroom practice remains a challenge, also because the time resources required may conflict with other goals. In a cluster-randomized controlled intervention study with 29 teachers and 604 students (mean age 15.6 years) at…

This study aims to describe the effect of the Nyerayo-based Science, Environment, Technology, and Society learning model on the scientific literacy skills of elementary school students in East Kluet District, South Aceh Regency. Learning Science, Environment, Technology, Society (SETS) has an important role in improving the scientific literacy and…

The Energy and Momentum Conceptual Survey (EMCS) is a multiple-choice survey that contains conceptual problems involving a variety of energy and momentum concepts covered in a typical introductory physics course for science and engineering majors. Prior studies suggest that many concepts on the survey are challenging for introductory physics…

This study aimed to develop a standardised instrument for diagnosing science misconceptions in primary school children. Following a developmental research approach using the 4-D model (Define, Design, Develop, Disseminate), 100 four-tier multiple choice items were constructed. Content validity was established through expert evaluation by six…

The method for producing monoclonal antibodies (MAbs) was first published in 1975. MAbs have revolutionised research, diagnosis, and disease treatment approaches. While students need a good understanding of MAb production, teaching the key steps via traditional methods can be challenging. Numerous resources exist, but these focus on hybridoma…

Online assessment is an essential part of online education, and if conducted properly, has been found to effectively gauge student learning. Generally, textbased questions have been the cornerstone of online assessment. Recently, however, the emergence of generative artificial intelligence has added a significant challenge to the integrity of…

This research is quantitative research to determine the effect of using the Discovery Learning model to assist animation video on the critical thinking skills of students grade XI on the digestive system. The research method used is Quasi Experiment with a Non-equivalent Control Group Design and used purposive sampling. The research instruments…

Anatomy and physiology courses are foundational in nursing education but are often perceived as challenging due to heavy content load. Innovative teaching methods, including social media platforms like Instagram Reels, may enhance student engagement and learning. In this quasi-experimental pre-post-test design with a control group, we examined the…
