Analysis of collisions is standardly included in the introductory physics course. In one dimension (1D), there do not seem to be any unusual issues: Typically, the initial velocities of the two colliding objects are specified, and the problem is to find the final velocities. In 1D there are therefore two unknown variables. One can write the…

In recent years, smartphone sensors have been frequently used in educational demonstrations to improve students' understanding of certain physical kinematic topics. In particular, the sensors on modern smartphones enable students to use their phones as physics mini-laboratories, and they have been used to analyze objects' speeds and accelerations…

Background: While there has been increasing recognition of the importance of attending to students' views about what counts as knowing and learning a STEM field, surveys that measure these "epistemological" beliefs are often used in ways that implicitly assume the fields, e.g., "physics," to be a single domain about which…

The conical pendulum is a topic theoretically approached in physics literature, but with little experimental activity developed due to the difficulty of reproducing the conical motion in ideal experimental conditions. This work consisted of studying the motion of a rigid conical pendulum using video analysis. The experimental results were used as…

This study aims to measure Brewster's angle of glass and acrylic brick with an easy-to-obtain mobile application (app) by changing the tungsten light source to a red laser. The popularization of the smartphone has inspired many to use its various built-in sensors to carry out general physics experiments. Many others have adopted both a laser and a…

Observing children tossing a ball in a game of catch or pumping their legs to move a swing, it is obvious that they have already experienced and learned to control the basics of pushes and pulls. Through everyday experiences as simple as rolling a ball across the floor, to more complex activities like team sports, children are building a…

In a classical electronic laboratory, there is an experiment where a diode is connected in a series with a resistor and a variable DC voltage source in order to draw the characteristic I-V curve of the diode. Input voltage is gradually increased starting from 0 V, and the potential difference between the diode's terminals is read by using a…

After targeted instruction designed to improve student conceptual understanding of physics, a significant fraction of students are not able to answer many questions in a consistent manner. Prior research suggests that even those students who demonstrate that they acquired the relevant knowledge and skills (i.e., possess the requisite…

Calls for reform to instructional labs mean many instructors and departments are facing the daunting task of identifying goals for their introductory lab courses. Fortunately, the American Association of Physics Teachers (AAPT) released a set of recommendations for learning goals for the lab to support lab redevelopment. Here we outline the…

New learning strategies try to extend the use of common devices among students in physics lab practices. In particular, there is a recent trend to explore the possibilities of using smartphone sensors to describe physics phenomena. On the other hand, the study of the moment of inertia by the use of the torsion pendulum is a typical example in the…

Gay-Lussac's law states that the pressure of an ideal gas is directly proportional to its absolute temperature if the volume is constant. Students observe this relationship by taking measurements on the pressure of gas in a flask or metal sphere at different temperatures and then extrapolate the data to estimate absolute zero. In our college…

This study aimed to compare the online and face-to-face teaching of a required algebra-based physics course for non-physics majors in large-enrollment course sections. The study design is quasi-experimental; the students self-selected to enroll in either the fully online and asynchronous course or the face-to-face course. In this study, we look at…

This paper describes the development of a light polarization experimental apparatus for a remote laboratory. The apparatus had been developed by controlling the analyzer rotation using a stepper motor controlled via the Arduino. Device control and data acquisition applications were developed with LabVIEW which provides remote control panel…

Models are at the heart of any physics discipline, and in recent decades physics education has shifted heavily toward teaching students how to think using models. Involving students in an investigation of a real phenomenon through measurements and the applications of models is an ideal learning experience for a physics student and is the aim of…

Metacognition inventory supports increased awareness and self-control to improve student's academic success, including physics. However, there are limitations to revealing the Physics Metacognition Inventory (PMI), especially in Indonesia. This study aims to explore and evaluate the psychometric properties of PMI. This survey research has involved…
