Experimental results are presented concerning the motion of a ball that bounces up an incline a few times then bounces back down again. The number of bounces up the incline is typically small since the speed of the ball in a direction parallel to the incline decreases rapidly, not only during each bounce but also while the ball is in the air. The…

About 30 years ago I taught a series of summer enrichment programs for high school physics teachers, using funding from the Howard Hughes Medical Institutes. I deliberately chose teachers from smaller cities and towns who were unlikely to have contact with other physics teachers. One of my more interesting teachers came from a rural area in a far…

Involving students in laboratory and inquiry-based activities can help them understand the concepts of physics. However the learning process should not only focus on the concepts. Moreover, the advantages of using virtual or physical labs are still under examination. The purpose of this study is to analyse which of the two modes (virtual or…

The use of texts is an indispensable resource for students' learning, especially in science domains. While developing understanding of a specific topic usually is the main goal of reading expository texts, an important consideration is how to best measure whether this understanding has been reached. In this study, we aimed to analyze gains in…

Difficulties in understanding physics concepts are often experienced by students such as in the material of regular uniform motion. This study aims to describe the mental models of first-year secondary school students on regular straight-line motion. This research utilized a case study method of 167 students at the secondary level with an average…

We consider the operation of the hypothetical mechanical vehicle driven by an engine powered by small rockets introduced by P D Hanstead in the inaugural volume of this journal. Hanstead arrived at three contradictory conclusions regarding the change in velocity should some of the rockets malfunction at a particular time. This thought experiment…

Students' challenges in learning mechanics are well documented from test situations, and group discussions are considered a fruitful way to meet these challenges. In this paper, we present a study from an authentic teaching setting where upper secondary students in groups solve the task of calculating the acceleration of an elevator by means of a…

Exploring students' physics conceptions, science engagement and misconceptions in physics together with their association to certain variables (gender, educational background, and program of study) are essential in improving physics teaching and learning. However, few studies have been conducted to explore these three measures and almost none…

Introductory calculus-based mechanics ("Physics 1") is an important gateway course for students desiring to pursue a science, technology, engineering, and mathematics (STEM) career. A major challenge with this course is the large spread in the students' incoming physics preparation. This level of preparation is strongly predictive of a…

The Force Concept Inventory (FCI) is a popular multiple-choice instrument used to measure a student's conceptual understanding of Newtonian mechanics. Recently, a network analytic technique called module analysis has been used to identify responses to the FCI and other conceptual instruments that are preferentially selected together by students;…

Despite recognising momentary challenges while learning, collaborative groups do not necessarily regulate and adapt their learning process according to the demands. Various online measures have recently been explored to unobtrusively study engagement and adaptation in collaborative learning (CL), as it occurs in the classroom. For example,…

Women, especially Black and Latina women, are marginalized in physics, including in high school classrooms. Recognition is one of the ways women and girls experience marginalization in physics. This dissertation is comprised of three distinct but related studies examining how students experience recognition in an AP Physics 1 classroom. The first…

This paper explores the views of leading Czech physicists regarding a physics curriculum for upper secondary schools. This paper presents the first part of an effort to define starting points for a new physics curriculum in Czechia (subsequent phases would analyze the opinions of other scientists, education experts, and physics teachers regarding…

The motion of a cylindrically or spherically symmetric body on an accelerated treadmill, inclined of an angle [theta] with respect to the horizontal, is described by means of Newtonian mechanics. By assuming that the conveyor belt has an acceleration "a[subscript O][superscript ']", not necessarily constant, and that the body rolls on…

This study analyses the effectiveness of directed vs. minimally directed inquiry-based instructional approaches in improving students' attitudes toward physics. It specifically compares the impacts of cognitively guided instructional strategy (CGIS) and Cubing instructional strategy (CIS) on student attitudes. Using a pretest--post-test…
