Vector calculus and multivariable coordinate systems play a large role in the understanding and calculation of much of the physics in upper-division electricity and magnetism. Differential vector elements represent one key mathematical piece of students' use of vector calculus. In an effort to examine students' understanding of non-Cartesian…

In this article, we describe how the Gaussian Gun, a simple configuration of magnets and ball bearings, can be leveraged to connect ideas from physics to representations and ideas that are central to chemistry and challenging for students to learn. In particular, we show how the Gaussian Gun, an arrangement of ball bearings and magnets, models…

Physics instructors recognize the value of kinesthetic experience in learning fundamental physics concepts. We describe a kinesthetic experiment appropriate for both college and high school physics students. The experiment helps students achieve an intuitive understanding of Newton's second law in a way they find quite enjoyable. It was devised by…

This work reports a rudimentary approach to teach and measure the kinetic friction coefficient using a smartphone that can effectively be employed for teaching purposes. More specifically, the kinetic friction coefficient, which is rather difficult to teach and measure, between various surfaces was determined by two different approaches using the…

Although students experience friction in their everyday life, they have difficulty understanding the scientific concept of friction. To solve this problem, various instructional suggestions have been made by researchers concerning the teaching of friction. In this study, we conducted a survey to investigate science high school students' reasoning…

Physics students have traditionally prepared many kinds of reports-- laboratory, activity, project, and even book or article reports. Smartphones and YouTube videos are familiar cultural objects to current students, and our students use smartphone cameras to include photographs of apparatus, phenomena, hand-sketched figures, graphs, and…

The structure and definition of professional knowledge is a continuing focus of science education research. In 2012, a pedagogical content knowledge (PCK) summit was held and it suggested a model of professional knowledge and skill including PCK, which was later often called the Consensus Model (Gess-Newsome, 2015. A model of teacher professional…

Electrostatic potential energy is a topic of great difficulty for many students. In this paper, we empirically test the utility of two approaches for laying a foundation for developing an understanding of energy in an electrostatic context, with interdisciplinary relevance. We examine student responses to a question about how the potential energy…

Providing diagnostic feedback about growth is crucial to formative decisions such as targeted remedial instructions or interventions. This article proposed a longitudinal higher-order diagnostic classification modeling approach for measuring growth. The new modeling approach is able to provide quantitative values of overall and individual growth…

The purpose of this study is to examine reflections of the design process of the Rube Goldberg machines on prospective science teachers' STEM awareness. A mixed design approach was opted for in this research. Data were obtained using learning diaries and a STEM awareness scale. Quantitative data was analyzed using a paired samples test. Content…

In the present article, a simple model for teaching the falling motion of a bungee jumper is presented and evaluated in terms of students' learning. The model allows one to make qualitative predictions about the accelerations of bungee jumpers with different masses and cord densities. The model was taught during a 90min teaching unit to physics…

The mystery tube is a fairly well known activity among science teachers for illustrating the nature of science. A variety of procedures have been presented for carrying out this activity, such as Scott Miller's method based on the BCSE 5E Instructional Model. Mystery tubes and other "black box" activities allow the students to engage in…

While circuitry lessons have traditionally been first introduced in late elementary school, they remain challenging conceptually for undergraduates in physics and engineering courses. Seeking to provide a higher quality and earlier introduction to circuitry learning for young children (ages 3-5), this paper investigates the affordances of…

This paper presents the creation of an educational resource using the camera of a mobile phone and video analysis software. The movie recorded is part of a daily context: an airplane's take-off. This work shows a way to introduce information and communication technologies (ICT) and digital educational resources (DER) as tools to teach and…

Scientific concepts are the building blocks of scientific thought and science communication. Therefore, to achieve scientific literacy it is necessary to construct and define the concepts accurately. In this study, the concept of friction force, which is frequently encountered in science textbooks, is discussed. The explanations of the concept in…
