In response to this, and contrary to the approaches based on computer tutorials, this paper introduces a set of laboratory experiments that analyze the above phenomenon from a practical perspective. The aim hereby is to visually demonstrate and clarify the main concepts of the photoelectric effect using real equipment. Specifically, the relationship between incident lighting (across different wavelengths and intensities) and the generated photocurrent is studied using a specially designed simple device. The experiments furthermore calculate the Planck constant, elucidate the linear relationship between photon energy and frequency, and prove that the stopping voltage is independent of the incident light intensity. Hence, the proposed experiments may foster a deeper understanding of the corpuscular nature of light among students.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"18 3","pages":"226-232"},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41962604","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}

Given that the role of engineering education has gained prominence within Science, Technology, Engineering and Maths (STEM) area, this work discusses some problems and strategies used in a case study developed with undergraduate students during the COVID-19 pandemic. The case study consisted of developing a mechanical ventilator adapting PBL strategies. The major challenge was to include groups of undergraduate students from some universities of Brazil, using only virtual platforms to collaboratively leverage design processes throughout technical-based teams for developing a low-cost mechanical ventilator. Therefore, this research covers two stages. The first was the action research, where professors and students worked together to develop the equipment. Then, after six months of activities entirely performed remotely, a questionnaire was made available to students to assess learning, motivation, difficulties, among others. This paper reflects these two moments at the project execution. The perception analysis of students’ learning and satisfaction demonstrates that the project provided a socialization space in times of pandemics. Finally, it was noticed that the totally virtual environment did not negatively impact students.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"18 3","pages":"199-210"},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41593197","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}

In this work, we focus on the use of video in the higher education space. In particular, we question whether summary videos of learning objectives and exercises can be used effectively to enhance learning. Recent methodologies and the new online paradigm have increased the use of Learning Management Systems (LMS), especially at the higher level education system. One of the advantages is that LMS allows the acquisition of objective data from student activity. In our study, we applied the video-mentioned methodology and further analyzed the student’s behavior. This allows us to provide a student categorization based on their online profile activity and concisely characterize their LMS platform interaction. The study was developed in an undergraduate Engineering degree course at the Universitat de València, allowing us to measure the success of video use for students. Our promising results indicate there is a relation between access to educational videos and the student’s academic performance, supporting educational videos can be effectively used to enhance learning.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"18 3","pages":"233-238"},"PeriodicalIF":0.0,"publicationDate":"2023-08-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42637642","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 research made it possible to forecast each student’s results and thus make decisions on reinforcement strategies to improve student performance. Therefore, a Learning Analytics approach based on three stages was developed: first, analysis and debugging of the database; second, multivariate analysis; and third, machine learning techniques. The results show an association between the performance levels in the Highschool test and the university test results. In addition, the machine learning algorithm that adequately fits the research problem is the Generalized Linear Network Model.

The research question explored here is as follows: what is the impact of Just in Time Teaching (JiTT) implementation on student academic achievements as measured by the grades obtained by engineering students in physics laboratories? We examined the research question by statistical analysis of the grades obtained by students before and after the implementation of the JiTT strategy. The statistical analysis showed an increase in the percentage of students with grades over 4.0/5.0 upon the implementation of this strategy. A significant difference between the grades obtained before and after implementation in the Physics I and Physics II laboratories was confirmed by ANOVA (p < 0.005); in contrast, in Physics III laboratories, we observed similar grades before and after the implementation. We conclude that the implementation of JiTT improves the grade distribution over higher values, suggesting that students have better learning outcomes; more efforts are needed in Physics III laboratories to achieve a similar (or greater) increase in grades than in Physics I and II.","PeriodicalId":38963,"journal":{"name":"Revista Iberoamericana de Tecnologias del Aprendizaje","volume":"18 2","pages":"190-197"},"PeriodicalIF":0.0,"publicationDate":"2023-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41512422","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}
