This study revises and enhances a guided inquiry activity designed to introduce undergraduate and high school students to the physiological concepts of exercise fatigue during a 400-meter dash. This activity has been employed since 2016 in entry-level human physiology courses at the University of Minnesota and across 30 high schools. Using…

Given the recently proposed three-filament theory of muscle contraction, we present a low-cost physical sarcomere model aimed at illustrating the role of titin in the production of active force in skeletal muscle. With inexpensive materials, it is possible to illustrate actin-myosin cross-bridge interactions between the thick and thin filaments…

Background: Cognitive load theory is widely used in educational research and instructional design, which relies heavily on conceptual constructs and measurement instruments of cognitive load. Due to its implicit nature, cognitive load is usually measured by other related instruments, such as commonly-used self-report scales of mental effort or…

The theory of socially shared regulation of learning (SSRL) suggests that successful collaborative groups can identify and respond to trigger events stemming from cognitive or emotional obstacles in learning. Thus, to develop real-time support for SSRL, novel metrics are needed to identify different types of trigger events that invite SSRL. Our…

Background: This study explored the physiological correlates of students' self-reported emotions in ecologically valid settings by combining biosignal data (on physical and cardiac activity) and experience sampling method (ESM) data. Aims: The aim was to examine the concurrent associations between self-reported excitement, calmness, anxiety, and…

The rapid development of information and communication technology has influenced the field of education, which can be utilized in the learning process through the application of technology in learning media usage. Abnormalities and disorders in the circulatory system are complex subtopics involving interconnected organs in the blood circulation…

Research suggests that students hold misconceptions about the immune system, but little is known about how they reason about the mechanisms by which the immune system operates. This study investigated how students reasoned about the immune system in Beirut, Lebanon. The study used a qualitative approach and investigated 16 Grade 12 participants…

Purpose: Changes in biophysiological markers related to perceived burnout and self-comfort were tested in this study. Method: Forty-two student-athletes from middle and high school grades were evaluated for burnout, salivary cortisol levels, measures of arousal-related physiological markers (i.e., blood volume pulse; BVP), galvanic skin response…

This study aims to develop e-worksheet teaching materials on the excretory system, assess their feasibility, analyze teacher responses, and evaluate trial results using the e-worksheet. The research follows a Research and Development (R&D) approach, employing the ADDIE development model. The study was conducted at SMAN 8 Tanjung Jabung Timur,…

Karate martial arts is one of the full body contact martial arts. In karate martial arts there are two types of categories namely Kata (art) and Kumite (fighting). In the kumite/fight (fighter) class, its success is greatly influenced by kime. The "kime" process occurs due to movements performed with speed, explosive power and strength…

Proteins are essential for cell function, and their biological performance depends on three-dimensional (3D) structures. Insulin is made up of 51 amino acids and is a critical hormone involved in glycaemia regulation. In basic education, concepts involving proteins (synthesis, structure, interactions, and function) are abstract and difficult for…

Using hidden Markov models (HMM), the current study looked at how learners' metacognitive monitoring is related to their physiological reactivity in the context of collaborative learning. The participants (N = 12, age 16-17 years, three females and nine males) in the study were high school students enrolled in an advanced physics course. The…

The present paper examines whether there exists a change in the concentration of carbon dioxide that is trapped in the surgical facemask during the procedure of respiration and whether the results of the sequestered CO[subscript 2] can have harmful effects on the human organism. In order to answer the research questions, an experiment has been…

The COVID-19 pandemic not only affected education at its peak, it continues to affect learning in its aftermath. High schools were forced to transition to remote learning, throwing students and educators alike into a new reality. Recovering from the pandemic has forced the need for innovative ways to engage students. Some successful attempts at…

The biology material on the excretory system has a high level of learning difficulty, including the complexity of the material and the high level of abstraction, which can affect students' learning process and outcomes. Therefore, it is necessary to analyze the internal and external sources causing learning difficulties by conducting research that…
