In recent years, the use of multiple representations in physics teaching and learning has become more common. This study sought to determine if engineering students’ performance in Rwanda might be improved by the use of numerous representations when solving mechanics problems. Multiple representations improve students’ comprehension and recall of mechanics ideas, supporting efficient teaching methods and critical thinking. This study employed a quasi-experimental research design with pre-and post-test control and experimental groups. A total of 100 students were enrolled in the study, divided into two groups: the experimental group consisted of 52 students who received instruction using multiple representations, and the control group consisted of 48 students who received instruction using traditional methods. In the study, students’ performance was measured before and after intervention using a mechanics test. The mechanics problem-solving pre-test findings indicated a p-value greater than 0.05 between the control and experimental groups, indicating no statistically significant differences between the two groups. A post-test revealed a p-value < 0.001 between the groups, indicating that the experimental group outperformed the control group significantly. According to the findings, engineering student’s academic performance in physics can be improved through the use of multiple representations in teaching and learning mechanics problem-solving. This study will support the development of Rwandan education policies, instructional approaches, and global pedagogy are all supported by this study.
近年来，在物理教学中使用多种表征已变得越来越普遍。本研究旨在确定在解决力学问题时使用多重表征是否能提高卢旺达工科学生的成绩。多重表征可以提高学生对力学思想的理解和记忆，支持高效的教学方法和批判性思维。本研究采用了准实验研究设计，分为前后测试对照组和实验组。共有 100 名学生参加了研究，分为两组：实验组由 52 名学生组成，他们接受了使用多重表征的教学；对照组由 48 名学生组成，他们接受了使用传统方法的教学。在研究中，学生的成绩在干预前后通过力学测试进行测量。力学问题解决前测结果显示，对照组和实验组之间的 p 值大于 0.05，表明两组之间没有显著的统计学差异。后测结果显示，两组之间的 p 值小于 0.001，表明实验组的成绩明显优于对照组。研究结果表明，工科学生的物理学习成绩可以通过在力学问题解决的教与学中使用多重表征来提高。这项研究将为卢旺达教育政策、教学方法和全球教学法的发展提供支持。

Classical mechanics has long been a conceptually challenging topic for students. Escape Experience Aeroseum offers a novel approach to help address this issue by integrating classical mechanics into an educational escape room (EER). The escape room creatively combines physics with aerospace engineering principles, with the aim of aiding learners in making more sense of classical mechanics concepts through solving interactive, hands-on challenges. In the paper, we discuss the design and educational potential of Escape Experience Aeroseum, including the need for adaptability and appeal across different educational settings. By introducing an EER centered around classical mechanics, this work contributes to the growing interest in developing and evaluating EERs as a possible means to increase students learning, engagement, and interest in physics.

A simple do-it-yourself (DIY) apparatus is designed and built for the measurement of the electrical resistivity of materials. The tool is portable and easy to operate, and students/new researchers can build their own apparatus with a minimum amount of time and raw materials. The apparatus’ spring-loaded four-point probes help provide a good electrical contact between the sample surface and the probes. It has been checked for its reliability by comparing the resistivity data with literature values and the measurements match well with the previous data. The apparatus is suitable for measurements from room temperature to ∼100 °C.

Assigning students the seemingly simple task of drawing the Moon’s trajectory in the heliocentric system can ignite a profound discussion about the intricacies of the trajectory. This article presents a diverse set of plots depicting suggested trajectories, alongside a detailed discussion of their differences and the implications of various details. The provided reasoning exemplifies analytical thinking, showcasing how even a small dataset enables us to dismiss certain suggested trajectories (hypotheses).

The article presents an experiment for studying the Doppler effect using the Arduino sensor integrated with LabVIEW to detect the frequency of the rotating sound source. A mobile phone application is used as a sound generator emitting 500–1100 Hz frequencies and rotated in a uniform circular motion. The Arduino sound sensor is affixed at rest, acting as a listener to observe the frequency of the mobile phone moving toward and away from it. This experiment can express a significant concept of the Doppler effect concerning a shift in the observed frequency of a sound wave when the sound source moves relative to the observer. Moreover, students can interpret a graph and calculate the tangential speed of the rotating mobile phone.

In this study, we employed the harmonic series experiment to determine the end correction factor of the Indonesian Angklung. Indonesian Angklung are categorized as one-closed-end resonance tubes and consist of different lengths that represent different musical notes. The end correction factor of the Indonesian Angklung is determined from the L-intercept of Lres versus 1f graph. The findings indicate that the experimental values of the end correction factor are less than 6.00% compared to theoretical values. Hence, the harmonic series experiment can be utilized to determine the end correction factor of the Indonesian Angklung.
在这项研究中，我们采用谐波序列实验来确定印尼 Angklung 的端部修正系数。印尼 Angklung 被归类为单封端谐振管，由代表不同音符的不同长度组成。印尼 Angklung 的末端校正系数是根据 L res 与 1 f 关系图的 L 截距确定的。研究结果表明，与理论值相比，末端修正系数的实验值小于 6.00%。因此，可以利用谐波序列实验来确定印尼 Angklung 的末端修正系数。

This study presents an internet-connected calorimeter allowing both face-to-face and online laboratory activities. This device aims to create an environment that facilitates enquiry-based teaching strategies. There are three ways to access the device: (i) remotely via the web (WAN—Wide Area Network), locally (ii) through the local network (LAN—Local Area Network), or (iii) as a stand-alone device. It was designed with a client-server structure and utilised the Flask framework in Python. The instrument consists of two isolated containers (calorimeters), allowing for investigative activities that include comparing two liquid samples. The system was built using low-cost components based on the Arduino platform. Unlike virtual laboratories, measurements are performed on real devices. We present the results of direct electrical heating for a short time and record the temperature step of the samples. This straightforward method has proven to be suitable as a learning activity because of its conceptual clarity and effectiveness in teaching and learning. The use of a mechanical stirrer to homogenise the temperature of the liquids is crucial for obtaining high-quality experimental results. The system described in this paper is part of ‘RLab project’, an initiative to develop a platform for remote Experimental Physics Activities in Physics Teaching for public schools in Brazil. This experimental setup can be highly beneficial for implementing an experimental learning methodology, especially in the case of—but not restricted to—distance learning.
