There have been many recent articles in this journal highlighting simple demonstrations of a wide variety of acoustic phenomena. In introductory physics courses, sound waves and their propagation through air, and resonance in musical instruments, are covered in detail. However, attention is not usually paid to the active role that our ears play in…

The use of video analysis for the study of motion and forces is well established in the worlds of physics and biomechanics. The issue of parallax error, sometimes referred to as perspective error or scaling error, when videotaping a moving object is known, and the experimenter is often counseled to be "far away." However, "far…

A journey through the wonderful world of spinning tops, emphasising their practical use in both amusement, skill and as part of the physics curriculum.

We have designed an Arduino-based experiment to check the linear relationship between charge and voltage drop in a capacitor. The electric charge stored in a capacitor is determined by the numerical integration over time of the electric current during the charging or discharging processes through a resistor. Instead of using scientific software to…

In this study, the aim is to take the views of pre-service teachers on study sheets and evaluate these views. Problem question of the study was determined to be "What are the views of pre-service physics teachers on study sheets?" In this study, which was realized in accordance with the aims of qualitative research, a case study model…

Physics education research over the past few decades has made significant advances toward improving instructional practices and developing effective instructional materials for physics classrooms. In some contexts, however, after multiple instructional refinements difficulties can remain persistent. Recent findings in PER suggest that many of…

This mixed methods study explores college biology students' perceptions of the utility of evolution knowledge. In Phase I, 14 college biology students from an upper-level Evolution course were interviewed about their evolution acceptance and perceptions of the utility of evolutionary knowledge. In Phase II, findings from Phase I were used to…

Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…

The "Primary SPACE Project Research Report: Sound" (Watt and Russell, 1990) provides interesting reading relating to primary-aged children's concepts of sound. It reveals a range of children's views on how sound is made, how sounds are heard and how sound travels. While some children are shown to have knowledge that sounds travel and are…

This paper presents improvements made to a computerized adaptive testing (CAT)-based version of the FCI (FCI-CAT) in regards to test security and test efficiency. First, we will discuss measures to enhance test security by controlling for item overexposure, decreasing the risk that respondents may (i) memorize the content of a pretest for use on…

Inquiry-based representation-focused approaches in science education have shown promising outcomes when students engage in knowledge building via an active process of constructing, coordinating, and evaluating representations. To date, much of the existing research around these approaches has taken place in pre-digital classrooms, but the…

The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

The real-time graphing of simple harmonic motion of mass on springs with an Arduino based on an experiment set for teaching and learning physics in high schools where students can learn from real experiences. The objectives of this study are to create and develop a real-time measurement for vertical oscillations of mass on springs using the…

The innovation calls insist on the fact to identify new forms and models of learning and teaching. Actually, the educational approaches that encourage effective learning among student, is the Investigative Approach, which demonstrates more and more its potential in teaching. It is a scientific approach based on questioning and investigation where…
