Inquiry-based instruction has played an important role in science education, and been recognized as a critical approach to improve students' scientific learning effectiveness. However, current research revealed that it is a challenge for teacher education programs to improve pre-service science teachers' inquiry-based instructional activity design…

This study examined the early implementation stages of the Modeling Method of Instruction (MMI) in the science classroom to find the most valuable strategies for effective implementation. In this qualitative study, eleven teachers were interviewed to uncover effective implementation strategies. Interview data were analyzed using the constant…

Dissertation objectives included investigating how environment and plant life history influence aspects of leaf vascular infrastructure that supports photosynthesis, as well as photoprotection of the photosynthetic process. Additionally, I aimed to engage students in science and plant biology through innovative teaching methods. In summer annual…

Here we demonstrate how data from the clinical pulmonary function lab can help students learn about the principle of airway-parenchymal interdependence. We examined the relationship between airway conductance (Gaw) and lung volume (thoracic gas volume, TGV) in 48 patients: 17 healthy; 20 with emphysema, expected to have reduced airway-parenchymal…

Chemistry experiments involving biological aspects are in high demand. This laboratory exercise blends biochemistry and physical chemistry, illustrates key concepts of the virus capsid surface, and is designed for a chemistry laboratory course for students majoring in biology in college. The experimental part provides a mastery of…

Analysis of results from research in cognitive science and discipline-based education in recent years suggests that student thinking and learning can be better understood and investigated by adopting a systemic perspective that recognizes the complex and dynamic interactions taking place within and across multiple interconnected and interdependent…

This study investigates alternative conceptions of chemistry concepts among Faculty of Science students at Palestine Technical University-Kadoorie. Students are found to have incorrect views about fundamental chemistry concepts. The study aims to identify these misconceptions, understand their origins, and their impact on students' comprehension.…

Forces and motion are at the heart of physics and children start learning from the moment they are able to interact with the world. Children as young as one year show surprise when a ball does not behave as expected. This is a tremendous bonus to learning physics, but it has hidden dangers: they only learn how things move on the Earth, where we…

The amount of protein in complex matrices such as food products is an important characteristic, at both a nutritional and a pedagogical level. There are several methods available for protein quantification, from simple UV absorption to mass spectrometry. The most common are based on the interaction of the proteins with colored compounds followed…

The mercury beating heart is a classic demonstration to introduce redox reactions in the classroom. Here we report a new, safer demonstration: the Galinstan beating heart. Galinstan is a commercially available eutectic alloy composed of gallium (68.5%), indium (21.5%), and tin (10%) that has low toxicity. When an iron nail touches the Galinstan…

The Wilson cloud chamber is an apparatus used for detecting and observing the trails of alpha/beta rays or even cosmic rays in saturated gas conditions. The principle of this device is based upon the powerful ionization of the aforementioned rays within the medium. This article will provide instruction for creating a classic version of the cloud…

A classical mechanical structure with an internal degree of freedom is shown to reflect off a potential well. Such behavior is impossible for point-like or rigid classical particles. This numerical study provides insight for students studying internal energy and degrees of freedom.

It is well known that the needle of a compass in a magnetic field deflects, and that a compass near a conductive wire carrying a stable electric current deflects its needle. The only explanation of this observation is that the current-carrying wire creates a magnetic field around it. The strength of the magnetic field at any point near the wire…

If a ball rolls in a circular path on a horizontal surface at constant speed then its horizontal rotation axis changes direction with time. A simple experiment is presented showing that the torque applied to the ball is equal to the rate of change of its angular momentum, even though the magnitudes of its angular velocity and angular momentum…

Enrico Fermi is remembered for his many contributions to theoretical and experimental physics, but from an educational point of view he also popularized the use of the kind of questions we now call "Fermi problems" (or "Fermi questions"). Fermi problems (FPs) are back-of-envelope problems that arose from the need to make order…
