If a body is in equilibrium under the action of three non-parallel coplanar forces, the forces must be concurrent, that is, must meet at a single point. Specific examples are provided here to illustrate the validity of this statement by the use of free-body diagrams as well as during the discussion of equilibrium and moments. These cases are…

In our everyday life, it seems that magnetic phenomena are restricted to ferromagnetic materials or electromagnetism caused by electric currents. From a physics point of view, we know that this everyday experience is contrary to the nature of magnetic phenomena. If one regards the magnetic properties of the elements of the periodic table in their…

We have designed a simple Arduino-based experiment to study free fall. The experimental data associated to the free and vertical fall movement of a brass saucer are gathered with the help of an ultrasonic distance sensor and an Arduino board. The position-time curves obtained from different initial heights are then plotted and the acceleration of…

Ambient ionization mass spectrometry enables rapid in-situ analysis of a plethora of analytes that are relevant to the forensic and defense communities. As the arsenal of ambient ionization techniques, aimed at solving specific targeted problems, continues to expand, the adoption of these techniques into non-academic settings has been relatively…

This qualitative case study delved into students' understanding and positioning while they participated in solving an authentic, conceptually-based problem in a high-school chemistry class. Verbal and nonverbal cues, particularly gestures, offered broader awareness of students' engagement in sensemaking during the learning experience. The…

Understanding particle motion in force fields (PMFF), which encompasses the nature of forces and the relationship between force and motion, is fundamental to mastering mechanics and electromagnetism. Effectively solving PMFF-related problems requires advanced reasoning skills and the ability to apply knowledge across diverse contexts. Despite…

This article describes how a class dedicated to supporting language needs in concurrent science courses developed complex grammatical literacy with an emphasis on a functional understanding of language for technicality, precision, and persuasion. The success of the curriculum was predicated on three factors: the grammatical content selection and…

In an effort to promote integrated STEM education, the Malaysian government has integrated STEM teaching framework within the science and mathematics curriculum specifications to guide the science and mathematics teachers to design and implement interdisciplinary teaching while teaching science and/or mathematics concepts. Some of the factors that…

Background: There is a growing view that 'Big Ideas of science education' are useful for teaching science but there is not much knowledge of how teachers work with them. Purpose: This study explores the conceptualisation and practice of the use of Big Ideas of science education by primary and secondary teachers in Chile. Sample: A total of 63…

The purpose of this experimental study was to examine the effectiveness of the keyword strategy, one of the mnemonic strategies, in learning science concepts for middle school students with specific learning disabilities (SLD) in Türkiye. The participants were 27 middle school students between the 5th and 8th grades receiving supplemental…

Abstract concepts, such as gravity, may provide the perfect opportunity to bring phenomena into the classroom. As a knowledge generation strategy, summarizing can foster that opportunity. Using phenomena and summary writing together might help student learning since it requires making connections between their ideas and words to explain the…

This study aimed to compare the effects of computer-based lessons versus traditional lessons on achievement of university students regarding meiotic cell division. A pretest-intervention-posttest design was used. To determine the effect of our computer-based intervention, we established a control group. In total, 100 second-year university…

A widespread call has been made to develop and support more integrated approaches to STEM education. The first law of thermodynamics serves as a guiding principle for the crosscutting concept of energy and matter. A qualitative interview study was undertaken to support integrated approaches to STEM education by exploring how chemistry, physics,…

The research aimed to 1) build and assess suitability of the learning management plan of the predictive-observation-explanatory (POE) technology based learning approach to promote scientific explanation making about the change of the substance for primary school students, 2) to distill the lesson learnt of the predictive-observation-explanatory…

Background: Recent studies have highlighted the application of STEM (Science, Technology, Engineering, and Mathematics) knowledge into daily life via hands-on practical works. The limitations of the existing conventional laboratory work can be potentially overcome by the implementation of the innovative use of smartphones as an experimental tool…
