Background and Purpose: The purpose of this research was to find out how virtual reality instruction affected students' conceptual understanding of physics concepts. Method: This study used a quasi-experimental approach with control groups before and after the test. 117 SSII physics students comprise the study's sample chosen at random from two…

Engaging in interactions with peers is important for student learning. Many studies have quantified patterns of student interactions in in-person physics courses using social network analysis, finding different network structures between instructional contexts (lecture and laboratory) and styles (active and traditional). Such studies also find…

The purpose of this publication is to bring attention to some physics problems whose answers seem to be paradoxical and, at first glance, do not agree with a limiting case check. Solving a problem on the motion of a system consisting of two masses and a spring, it is natural to examine the answer by considering a case when a spring constant is…

Measurement instruments of physics, especially those dedicated as teaching aids in physics classroom are improving. These measuring instruments are not only used for measurement purposes, but also to apply theoretical concept into the real world, thus making it easier for students to comprehend. Therefore, this study aims to design, construct, and…

Purpose: The purpose of this study was to evaluate the effects of nonmodal phonation on estimates of subglottal pressure (Ps) derived from the magnitude of a neck-surface accelerometer (ACC) signal and to confirm previous findings regarding the impact of vowel contexts and pitch levels in a larger cohort of participants. Method: Twenty-six vocally…

The Phantom Bouquet is a venerable lecture demonstration that does a fine job of showing how a concave spherical mirror can form a real, inverted image. In the original demonstration, a brightly illuminated artificial rose is hung by its stem in front of a concave spherical mirror. The distance from the reflecting surface to the rose is somewhat…

Thomas Young (1773-1829) is best known in the physics community for his double-slit experiment demonstrating the wave property of light and for his work on the tensile properties of solids (Young's modulus). His reputation as a physicist was built almost entirely upon a short, three-year period (1801-1803) of intense work as an instructor in…

The hydrogen spectrum is one of the most commonly demonstrated and most commonly studied. After the visible spectral lines (Balmer series) are explained by the Rydberg's formula, it becomes immediately apparent that there will also be similar infrared and ultraviolet series. As you may have taught your students, these are called the Paschen and…

The location of the center of mass of a beam can be calculated using the values of the reaction forces at its ends. The success of an apparently erroneous solution leads the authors to seek and find an explanation for why this solution works. We illustrate the procedure with an asymmetric beam.

The Augmented Reality (AR)-based learning environment not only provides educators with novel ways to present learning materials but also give learners the opportunity to spontaneously interact with the material. Previous studies have shown that AR has many advantages in education; however, few focuses on the mechanisms behind promoting inquiry…

Since 2015, Germany has officially registered over 1.3 million refugees, many fleeing the Syrian civil war during the most recent European migrant crisis. The majority reaction of 82 million German citizens and their government to the crisis led to the welcoming culture ("Willkommenskultur")--the development of multiple government,…

In this study, we evaluate the validity of question 29 (Q.29) in the Force Concept Inventory (FCI), which requires an understanding of atmospheric pressure. At least in some Japanese physics classes, the rate of the correct answer to Q.29 is reduced between the pretest and post-test. To examine this deterioration of a student's response, we…

We present a thermodynamics experiment suitable for first year undergraduate students employing Stirling Engines to create a demonstration of energy transformation and to measure the mechanical efficiency of such engines. Using an inexpensive transparent chambered Stirling Engine, students can connect concepts such as the theoretical…

Distance learning in physics is still facing challenges, mainly due to the difficult access to a laboratory for practical work. Practical work is an essential part of the physics classroom because it allows students to interact with authentic physics phenomena and develop their scientific abilities. In this paper, we propose alternative…

Building a technology-driven world appears to be the main motivational force behind students choosing to undertake engineering studies. The first year of engineering education plays a significant role in demonstrating sufficient mathematical and scientific rigor to satisfy these motivational factors. The common applied mechanics courses play a…
