As a result of the pandemic, many physics courses moved online. Alongside, the popularity of Internet-based problem-solving sites and forums rose. With the emergence of large language models, another shift occurred. One year into the public availability of these models, how has online help-seeking behavior among introductory physics students…

This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

The Technological, Pedagogical Content Knowledge (TPACK) model serves as a comprehensive conceptual framework that delineates the essential knowledge domains teachers must possess to effectively integrate technology within educational settings. By synthesizing technological knowledge, pedagogical knowledge, and content knowledge, TPACK empowers…

This study employed a case study methodology to investigate students' misconceptions about solid, liquid, and atmospheric pressure. The research included 36 8th-grade students from various middle schools in Giresun, comprising 19 girls and 17 boys. Data collection involved a test consisting of 14 concept cartoon questions, and the concept cartoons…

This study was aimed at assessing the research trends in the family resemblance approach to the nature of science (FRA-to-NOS). This was accomplished through bibliometric analysis using the R program and a literature review employing the analysis framework. The findings demonstrated that the field of FRA-to-NOS has been experiencing growth, with…

We conducted an observational exploratory study of distraction by digital devices in multiple different sections across three large undergraduate physics courses. We collected data from two different settings based on the type of devices used for classroom polling: lecture sections that required mobile devices for polling and those that used…

Researchers have reported that participation in agricultural education reinforces STEM concepts. The use of projects is common in agricultural education. However, the foundational understanding of certain tenets of project use is not clear. A quasi-experimental study was conducted to test the effects of project authenticity on learning. AFNR…

For nearly two decades, augmented reality (AR) has found diverse applications in education, particularly in science education, where its efficacy has been supported by relevant theories and many empirical studies. However, previous studies have revealed the following research deficit: While AR technology appears to influence learning-related…

Assessment feedback is an essential way to promote student learning. Students and teachers may benefit from educational technologies during the feedback process. The purpose of this study was to identify the feedback dimensions that were fulfilled by iPad applications (apps) and to compare teacher practice to the affordances of apps. Typological…

[This paper is part of the Focused Collection on Curriculum Development: Theory into Design.] When we examined student responses to questions about the direction of the static friction force in various situations, we both had strong ideas about how to write a tutorial to promote deeper understanding. But our ideas were quite different. In this…

In the light of own measurements on a Faraday generator, the well-known theories concerning Unipolar Induction and the Faraday paradox seem to be problematic. On the other hand, all results obtained, and all other processes described as a paradox in connection with the Faraday generator can be explained without contradiction based on the theory of…

Important changes were recently made to the International System of Units. The readers involved in chemistry and physics, either teachers or advanced students, should be aware of the new definitions of the kilogram, the mole, and more generally of the changes in International System of Units (SI, "Système International") recently…

Einstein's theory of general relativity (GR) provides the best available description of gravity. The recent detection of gravitational waves and the first picture of a black hole have provided spectacular confirmations of GR, as well as arousing substantial interest in topics related to gravitation. However, to understand present and future…

In a familiar demonstration, a hoop and a solid disk of the same diameter and mass are started from rest at the top of an inclined plane and race to the bottom. The disk reaches the bottom with a larger speed than the hoop and arrives first. Why?

A standard physics experiment for students is to measure the terminal velocity of an object in air or in glycerine. A more difficult challenge is to measure the terminal velocity in water since the depth of the water needs to be large or the object needs to be dropped in the water at a speed close to its terminal velocity. Results obtained by…
