| Abstrak | : | What is the most powerful factor in teaching and learning? Different people have different answers, arising from different experiences. My experiences during four decades of university and high school teaching on three continents lead me to the following thesis: a loving care, concern, and compassion for the total welfare of our students, like that of good parents for their children (henceforth called parental care), is the most powerful factor in teaching and learning. This confirms the October 2015 TPT Editorial statement, “Teaching and learning … deeply depend on relationships that teachers and students develop with each other.”1 This is not new. Teachers being in loco parentis (in the place of parents) was an ideal and norm long ago, and a high percentage of teachers practiced it. It would be good to get back to this old ideal. |
Is There a Buoyant Force That Acts on a Submerged Object with No Liquid Under It

| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 682-683 |
| Abstrak | : | The purpose of this study is to determine whether an object fully submerged, but with no liquid under it, is lightened by a buoyant force or not. In addition, we develop an experimental protocol that allows us to measure the force exerted on this object by the liquid, and its dependence on the height of the liquid above it. This experiment allows academics to explicitly show the link between buoyancy and Stevin’s law. |
NarraCubes: A Virtual Dice Simulator to Incorporate Storytelling in Physics Classes

| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 678-681 |
| Abstrak | : | NarraCubes is a digital tool created to replicate dice rolls, specifically designed for educational purposes in high school and undergraduate classrooms. It is intended for use by students during in-class assignments and assessments, as well as by teachers in training programs. The tool aims to incorporate storytelling into basic or conceptual physics courses. The simulator was created as part of the physics education course at Instituto Federal de Educação, Ciência e Tecnologia do Ceará. In the Physics Teaching Methodology (PTM) classes, we used story dice to actively engage undergraduate students in the practice of storytelling |
Experiments on Yellow Light Using a Dark Box and Plastic Colored Cats
| Pengarang | : | Erdo?an Özdemir; Sebahattin Kartal |
| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 676-677 |
| Abstrak | : | In this study, a box, which we call a dark box, is made to keep out light and has a peephole for looking inside. Colorful remote-controlled RGB light-emitting diode (LED) lights and yellow, white, and blue plastic objects, shaped like cat masks, were inserted inside the box. We prove by several experiments using the dark box that light that appears yellow can consist of red and green light. |
An Inexpensive Armillary Sphere for Introductory Astronomy

| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 673-675 |
| Abstrak | : | Three-dimensional thinking is one of the most difficult skills introductory astronomy students struggle with. For instance, how does one’s latitude on Earth and the time of year affect the path of the Sun and stars across the sky? Why is the Sun high overhead at noon in June (in the northern midlatitudes) but not so in December? How does the time the Moon rises depend on its phase? Typically, astronomy instructors use diagrams, animations, and a lot of hand gestures to try to convey these concepts. Here I present a simple 3D model of the celestial sphere (see Fig. 1) that can be used in conjunction with 2D representations. |

| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 669-672 |
| Abstrak | : | During the last decade, major advancements in prototyping tools such as Arduino1 for managing sensors and data acquisition2 have been made. Arduino is a low-cost microcontroller board, an open-source electronics platform based on easy-to-use hardware and software.3 Some advantages of Arduino use are money saving for schools and universities,4 reliable measurements,5 and promotion of STEM programs.6–8 Additionally, Arduino can help make the educational experience more interesting and fun for students.4,9 This easy-to-use tool has led many teachers and researchers to develop experimental setups performing physics experiments in many subjects such as mechanics,4,6,10 optics,3,11 thermodynamics,12–14 waves,1,15 electricity,9,16 magnetism,17,18 modern physics,19 and energy. |
Bicycle-Powered Centrifuge: A Multidisciplinary Physics Lab Project to Engage Kinesiology Students

| Abstrak | : | The introductory physics sequence is a requirement for many undergraduate life-science majors. Pre-health profession students tend to have an unfavorable attitude toward taking a physics class.1,2 One method to improve attitudes is to integrate components of real-world applications.3,4 In this paper, a lab is presented that integrates principles of exercise physiology and physics to create an experience that benefits a variety of students. |
Analysis of the Effect of Ferromagnetic Materials on the Flux Density of a Solenoid, Using Open-Source Software and Applications
| Pengarang | : | Derek Dorbação de Araujo; Frederico Alan de Oliveira Cruz |
| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 662-664 |
| Abstrak | : | The magnetic field induced by a coil of wire or a solenoid is a theme present in physics classes in high school and university education, with great emphasis on the equations and laws used to estimate the value of some quantities. One issue, in our view, is that most of the time students just memorize mathematical expressions to obtain a numerical result that makes little sense, without understanding exactly what happens and why. This situation confirms that mastering algebraic elements does not seem to be enough for understanding physics, as already shown by Bing and Redish. |
Visualizing Light Beams Diffracted by a CMOS Sensor with a Fluorescent Dye

| Nama Majalah/Jurnal | : | The Physics Teacher |
| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 658-661 |
| Abstrak | : | Complementary metal–oxide–semiconductor (CMOS) sensor chips, made by an advanced manufacturing process, can be used for demonstrating two-dimensional diffraction since many pixel units are arrayed on the chip periodically. Coincidentally, the CMOS sensors in discarded cameras or smartphones have small pixel sizes, close to visible light wavelength. Compared with the already packaged chips with periodic structures, the CMOS periodic surface is protected by one or two transparent glass sheets (filters). |
Reinventing the Wheel: An Alternative Rotational Inertia Lab for Introductory, Calculus-Based Physics

| Volume / Edisi | : | 62 (No. 8) |
| Halaman | : | 656-657 |
| Abstrak | : | Rotational inertia is one of the most challenging topics in the first-year physics course. In the calculus-based AP Physics C course, rotational inertia comprises up to 20% of the AP mechanics exam1 and often comprises the most challenging Free Reponse Question on the AP exam. Specifically, rotational inertia’s heavy reliance on integral calculus makes it a standout unit in the introductory physics course since students often learn the required calculus concurrently or even after learning rotational inertia. The combination of challenging conceptual physics content and a reliance on more advanced math skills makes rotation an essential topic to focus on in order to build intuitive understanding. Consequently, the need exists for a high-quality and user-friendly rotational inertia lab that reinforces and strengthens students’ conceptual understanding of the topic. |
