Bickel, Klaus; Denschlag, Robert – Physics Teacher, 2019
This work is inspired by a recent article in a German newspaper about the question of whether a 360 degree turn on an ordinary swing, that is, a seat suspended by chains, is possible. Although the author correctly negates the question, his remarks about the trajectory of the rocking person remain imprecise. Thus, we direct our attention to cases…

Didis Körhasan, Nilüfer – Journal of Turkish Science Education, 2021
As well as knowledge structures can be complex and coherent, they might be small and disconnected. This study focuses on knowledge elements of pre-service teachers using diSessa's phenomenological primitives (p-prims) framework. Based on group interviews, a test was developed regarding the knowledge fragments used for explaining free fall in three…

Hong, Seong Bock; Broderick, Jane Tingle; McAuliffe, Cynthia M. – Early Childhood Education Journal, 2021
As early childhood educators of young children, we recognize that children draw what they know from cultural transmissions, moving through many developmental transitions with drawing. As children's skills developed, a PreK/Kindergarten teacher in a university laboratory school classroom with 27 children was interested in studying ways children can…

Robertson, Amy D.; Goodhew, Lisa M.; Scherr, Rachel E.; Heron, Paula R. L. – Physical Review Physics Education Research, 2021
Existing research identifying common student ideas about forces focuses on students' misunderstandings, misconceptions, and difficulties. In this paper, we characterize student thinking in terms of resources, framing student thinking as continuous with formal physics. Based on our analysis of 2048 written responses to conceptual questions, we…

Cumber, Peter – International Journal of Mathematical Education in Science and Technology, 2021
Mechanical engineering students often find the formulation and analysis of dynamical systems difficult. The response of some mechanical engineering undergraduates is that as much as possible courses on mechanics are best avoided. The aim of this paper is to produce some interesting dynamical systems that may help to change the opinions of the…

Milsom, John A. – Physics Teacher, 2021
The classic brachistrochrone problem is standard material in intermediate mechanics. Many variations exist including some accessible to introductory students. While a quantitative solution isn't feasible in introductory classes, qualitative discussions can be very beneficial since kinematics, Newton's laws, energy conservation, and motion along…

Olsho, Alexis; Brahmia, Suzanne White; Smith, Trevor; Boudreaux, Andrew – Physics Teacher, 2021
Electromagnetism (E&M) is often challenging for students enrolled in introductory college-level physics courses. Compared to mechanics, the mathematics of E&M is more sophisticated and the representations are more abstract. Furthermore, students may lack productive intuitions they had with force and motion. In this article, we explore the…

Falfushynska, Halina; Kryzhanovskyi, Serhii; Korsun, Igor; Monchuk, Maryna – Physics Education, 2021
The aim of the present work is to demonstrate the expediency of using information technologies on the study of Brownian motion. The importance of using such software as VirtualDub, Tracker and Google Sheets for the study of Brownian motion has been substantiated. This made it possible to determine the values that cannot be measured directly (the…

Harshbarger, Dena; Wiechman, Joseph – Science and Children, 2021
This article describes a force and motion unit that spanned four weeks (50 minutes a day) in a fifth-grade classroom. The inquiry-based learning progression mirrors Piaget's Theory of Cognitive Development (1952) because it allowed students to manipulate materials and ideas as they actively constructed and reconstructed their knowledge of motion…

Polley, J. P. – Physics Teacher, 2021
While the three laws of conservation of energy, momentum, and angular momentum are all mentioned in introductory textbooks, there are few experiments through which students can investigate the conservation of angular momentum. Most experiments consist of collisions between rotating disks, in which one disk is dropped on another, or in which the…

Medel-Esquivel, Ricardo; Gómez-Vargas, Isidro; García-Salcedo, Ricardo; Vázquez, J. Alberto – Physics Teacher, 2021
One of the main topics of elementary physics is the idea that every material is composed of "little particles that move around in perpetual motion, attracting each other when they are a little distance apart, but repelling upon being squeezed into one other." These particles could be atoms or molecules. Atoms are the smallest part into…

Tomin, Milan; Scipioni, Marco; DeAngelis, Fred – Physics Education, 2018
In the sport of American football, the quarterback (QB) is the player almost always responsible for throwing the ball downfield to an open receiver. That important throw requires him to make a split second decision to launch the ball at the correct speed and angle to guarantee it lands directly into the hands of the receiver. In this paper we…

McLean, Doug – Physics Teacher, 2018
Every so often an article appears in the popular press pointing to the apparent confusion surrounding the topic of aerodynamic lift and alleging that even the "experts" don't fully understand it. This makes attention-grabbing copy, but it overstates the case. Actually, the science of lift is not in dispute. It is well understood in terms…

Eryilmaz-Toksoy, Seyhan – Journal of Theoretical Educational Science, 2022
In this research, it was aimed to analyze the problem solving strategies used during solving problems related to constant speed and constant acceleration motion, which are often used in graphs, according to the presentation of the problem (text and graph). The research was carried out with 119 students studying in the 11th grade. In the research…

Way, Jennifer; Ginns, Paul – Mathematics Education Research Group of Australasia, 2022
Previous psychological, neuroscientific, and educational research indicates that a focus on individual haptic modes of learning (touch, body movement, gesture, tracing), and on the development of emerging mathematical and scientific drawing, can enhance children's learning in mathematics and science. However, most of these studies have focused on…
