The purpose of this study was to examine the effect of STEM designed activities on academic achievement of 7th grade elementary school students in work and energy unit. For that purpose, four STEM activities were chosen to be implemented in the work and energy unit. Semi-experimental research design was utilized for the research. Two different…

A subject of physics includes various complex and sophisticated concepts that pose a challenge for both instructors to teach and students to grasp the clarity in the subject. Many researchers have discussed this challenge toward adopting an appropriate approach to teach physics in the institution. Therefore, the study reviews the research articles…

The ideal gas law, "PV = nRT," is one of the simplest physical laws in nature that is introduced to students as early as in high school and first year in college. In this equation, "P" stands for pressure, "V" is the volume, "n" is the amount expressed in mole, "T" is the temperature in Kelvin…

In this article we present a simple technique for determination of the Young modulus of the material of a metallic ruler using it as a cantilever. This method employs with a slide potentiometer and a digital multimeter. The linear region of potentiometer resistance which is calibrated in terms of length has been used to record the load vs.…

The refractive index of a liquid is known to depend strongly on the temperature gradient of liquids. When a laser beam passes through a transparent material going through thermal diffusion, the light projected onto a screen will be displaced in relation to the thermal diffusivity. A simple apparatus is used to measure the time evolution t of the…

Difficulties presented by students on the concept of instantaneous velocity are well known. This is in part due to instantaneous speed being often defined in terms of the notion of mathematical limit, which may not be clear to many students in introductory physics courses. In this work we present a complementary teaching proposal that can help…

Granular flows appear frequently in the natural world and in civil engineering applications. These flows can exhibit features which are surprising and counter-intuitive and are often used to test the limits of the classical continuum approximation for modelling of fluid flows. An important sub-class of the granular flows are the gravity-driven…

This study aims to determine Turkish high school students' misconceptions about the electric charge imbalance by using a four-tier misconception test, where the main questions are accompanied by a question about the reason for the answer, as well as student declarations about their degrees of certainty. A four-tier electric charge imbalance…

Teaching the noncommutativity of the product of matrices to high school or college level students is a difficult task when approached from a purely formal perspective. The aim of this paper is to present a simple experimental activity for teaching the noncommutativity of the matrix product, based on the Jones calculus, a mathematical formalism for…

We present an experiment designed to study standing waves in a tube with one closed end. Two smartphones are used, one to emit a sound signal with a chosen frequency and another equipped with a microphone to detect the sound pressure level inside the tube. Due to the finite diameter of the tube, the standing wave node (or antinode) appears…

In this work a review of the research on augmented reality (AR) and its use of the learning of physics in the classroom is carried out. These two concepts of technology and learning are interrelated. Teachers have pre-teaching concepts and methods (conceptual changes), with the aim of having a deeper understanding of physical concepts that occur…

Co-design is an increasingly common process for curriculum development in science education, where teachers and researchers work together to create curricula, drawing on mutual knowledge and expertise. In efforts to understand this process, I looked at design dilemmas that occurred during design meetings and categorized the ideas that emerged in…

Module analysis for multiple-choice responses (MAMCR) was applied to a large sample of Force Concept Inventory (FCI) pretest and post-test responses (N[subscript pre] = 4509 and N[subscript post] = 4716) to replicate the results of the original MAMCR study and to understand the origins of the gender differences reported in a previous study of this…

This paper describes the use of a smartphone's sensors to investigate the motion of a torsion pendulum to demonstrate energy conservation. The smartphone was placed on and attached to a metal disk hanging by a wire. The oscillation of the disk was measured using the smartphone's sensors to simultaneously record angular position, angular speed and…

We investigate upper-division student difficulties with direct integration in multiple contexts involving the calculation of a potential from a continuous distribution (e.g., mass, charge, or current). Integration is a tool that has been historically studied at several different points in the curriculum including introductory and upper-division…
