The activity has proven to be challenging but feasible. It features both collaborative and competitive elements thereby surely creating an energizing buzz in the classroom.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"42 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141119000","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}

How could we determine how much heating oil remains in the tank? In this paper, we ask students to engage in mathematical deduction to devise methods for approximating a solution to this intriguing engineering problem. The only tools that we have access to are measuring tape, and a long clean stick, so resourcefulness becomes key. We establish a mathematical relationship between the parameters that we have access to measure and the volume of oil that remains in the tank. Expanding the scope, we encapsulate this solution within a Jupyter Notebook (Python), allowing for the calculation of oil in any cylindrical tank.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"28 10","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140979933","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}

We carried out a two-dimensional analysis to examine the place of the lightwave in the high school physics curriculum. We administered a test to assess the conceptual understanding of secondary school and university students. The analysis of the curricula revealed several shortcomings in the teaching of geometrical and wave optics. Furthermore, the assessment of conceptual understanding revealed that a significant proportion of students have misconceptions about the wave concepts of lightwaves and that these misconceptions persist throughout their higher education.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"13 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140979558","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 reflection was made on the academic production of the research group ‘Teaching and learning of physics’. This group has posed a sequence of research questions has been raised to find out how physics teachers understand the relationship between physics and mathematics in the physics teaching process. In 2003 they studied the idea of ‘mathematical beauty’ in the early days of quantum mechanics, suggesting that there would be a difference between the way scientists assume the physical/mathematical relationship and the way physics is taught. In 2010, they wondered if there would be research in this field that would allow transformations in teaching focused on equations as the set of mathematical–physical relationships, finding that there are at least three trends. In 2019, they verified that despite the research in the literature, many students continue with the same reductionist idea about this relationship. In 2020, they made a proposal, showing a possibility of educating the teacher’s thinking for new understandings in this regard. The main conclusion is that it is possible to develop mathematization processes in the classroom from three specific phases that educate scientific thinking. The first phase tries to make the student aware of the existence of phenomenology and describe it. The second phase educates the study of nature in a systematic way, building the meaning of the organization of a physical system. The third phase promotes explanation and argument so that students achieve an explanatory model. These phases are configured as a criterion to guide the sequence of activities in a class, a set of classes or a complete course and have been worked on and tested in ‘physics didactics’ courses in a physics teacher training course.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140930365","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}
