Strategic Intervention Material (SIM) is an instructional learner material developed to enhance the academic performance of low-performing students. This study aimed to develop e-SIM and investigate its effect on the student's academic performance and learning motivation in Newton's Laws of Motion. The participants were 40 students from Grade 12…

Cosmic expansion is an important concept in astronomy. For ease of understanding, astronomers generally draw an analogy between cosmic expansion and the expansion of a spherical surface in 3D space. This study theoretically and experimentally investigates the laws governing the motion of particles on the surface of a balloon during expansion.…

This paper describes three methods of measuring the coefficient of restitution (CoR) for two different types of ball-on-ball collision. The first collision type (for which two different CoR measurement procedures are described) is a static, hanging steel ball forming part of a Newton's cradle arrangement, which is then hit by its adjacent…

We compare the period of oscillation of an ideal simple pendulum with the period of a more "real" pendulum constituted of a rigid sphere and a rigid slender rod. We determine the relative error in the calculation of the local acceleration of gravity if the period of the ideal pendulum is used instead of the period of this real pendulum.

Playground Physics is a technology-based application and accompanying curriculum designed by New York Hall of Science (NYSCI) to support middle school students' science engagement and learning of force, energy, and motion. The program includes professional development, the Playground Physics app, and a curriculum aligned with New York State…

Research on expertise suggests that a critical aspect of expert understanding is knowledge of the relations between domain principles and problem features. We investigated two instructional pathways hypothesized to facilitate students' learning of these relations when studying worked examples. The first path is through self-explaining how…

Background: Children are not blank slates when they begin school; they bring prior conceptions about the everyday world with them. These conceptions usually do not comply with accepted scientific views and have to be changed within the process of education. However, to do this effectively more needs to be known about the relationship between the…

The propose of this study is to study Physics Learning Achievement, projectile motion, using the Mathematica program of Faculty of Science and Technology Phetchabun Rajabhat University students, comparing with Faculty of Science and Technology Phetchabun Rajabhat University students who study the projectile motion experiment set. The samples are…

The focus of the current study is to understand which unique features of an immersive virtual reality environment have the potential to improve learning relative motion concepts. Thirty-seven undergraduate students learned relative motion concepts using computer simulation either in immersive virtual environment (IVE) or non-immersive desktop…
