Physics phenomena are widely viewed in daily life, and the technical nature of physics makes modern life seem to be simpler than it was many years ago. Physics teaching and learning, on the other hand, has not always been done effectively, especially in developing countries. This study aimed measured the effectiveness using mobile physics on…

The classical demonstration experiment on acoustic beats using two signal generators and a dual trace oscilloscope is an important ingredient in teaching the subject. This short laboratory note aims to point out what may be the simplest demonstrative experiment on acoustic beats to carry out in a classroom without employing any lab apparatus.

The Kaleidophone, invented by Charles Wheatstone (1802-1875) in 1827, is a delightful mixture of physics and art. A typical example of the device, dating from the latter part of the 19th century, is shown in Fig. 1. The upright rods, which are approximately 25 cm in length, are of variously circular, oval, square, and rectangular cross section,…

It is a common practice to fix a vertical gnomon and study the moving shadow cast by it. This shows our local solar time and gives us a hint regarding the season in which we perform the observation. The moving shadow can also tell us our latitude with high precision. In this paper we propose to exchange the roles and while keeping the shadows…

A routine problem in an introductory physics course considers a rectangular block at rest on a plane inclined at angle a to the horizontal. In order for the block not to slide down the incline, the coefficient of sliding friction, µ, must be at least tan a. The situation is similar for the case of a ball rolling down an inclined plane. In order…

While the radiometer is readily available as a toy, A. E. Woodruff notes that it is also a very useful tool to help us understand how to resolve certain scientific problems. Many physicists think they know how the radiometer works, but only a few actually understand it. Here we present a demonstration that shows that a radiometer can be thought of…

This study is about the dynamics of a sliding ladder leaning against a vertical wall. The results are understood by considering the motion divided in two parts: (i) for 0 = t = t[subscript s] with one degree of freedom, and (ii) for t > t[subscript s] with two degrees of freedom, where the separation is determined by the instance t[subscript…

This paper describes a number of active learning strategies based on implementing the Raspberry Pi as low-cost single-board computing device for carrying out physics laboratory activities. This Microcomputer-Based Laboratory (MBL) Project has been funded by the Baden-Württemberg Foundation and it encompasses the use of high-accuracy yet…

For several decades, scholars have studied the role of cooperation and its outcomes in educational contexts. Yet we lack a complete understanding of how different instructional strategies impact the relationship between cooperation and learning. In this paper we present results from a field experiment with 82 first-year students in an introductory…

In this research an instrument was developed to measure students' anxiety about the jargon of physics. Levels of anxiety were then compared with student content performance and general classroom anxiety. Anxiety levels were also compared based on students' language of origin (native vs. nonnative English speaking students). Statistical analyses…

The study was intended to examine the utilization as well as the availability of E-learning facilities in the teaching of senior school physics in Ilorin, Nigeria. The study was a survey type and all physics teachers constitute the population. A total of 60 teachers was sampled for the study. Multi-stage sampling technique was adopted in the…

The term "Virtual Reality" currently refers to a profound sensory immersion of the user in a synthetically generated virtual environment. It is foreseen that virtual reality will gain a substantial role in the instruction of science. In this literature review, the purpose was to investigate the research on the utilization of virtual…

In this paper, I (SH) will apply a counter-storytelling method to highlight a perspective that is not often present in the physics culture. The counter-storytelling (or counter-narrative) method gives voice to people from traditionally marginalized groups to share their untold experiences. Counter-storytelling, as the name implies, challenges…

The overall aim of the present study is to study model-based teaching and the collaborative inquiry learning of chemical processes and physical phenomena in preschool, with a specific focus on the verbal communication established between teachers and children (4-5 years old). According to variation theory, learning is always directed at a specific…

This research aims to implement the guided inquiry learning model to improve the understanding of concepts and critical thinking skills of Vocational High School (SMK) students. The quasi-experiment method with the randomized pretest-posttest control group design was used to obtain data from students of one of the Vocational High Schools (SMK) in…
