{"title":"Effect of using multiple representations in teaching mechanics problem-solving on engineering students’ academic performance in Rwanda","authors":"Niyomufasha Theogene, Celestin Ntivuguruzwa, L. Mugabo","doi":"10.1088/1361-6552/ad4944","DOIUrl":"https://doi.org/10.1088/1361-6552/ad4944","url":null,"abstract":"\u0000 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.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"64 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141106070","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"42 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141112949","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

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.

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.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"87 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141122976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
