Acoustic levitation is an application of standing-wave phenomena, growing in popularity through the recent adoption of low-cost ultrasound transducers. Nevertheless, acoustic levitation has not yet been included in the standard phenomena investigated in undergraduate and upper-secondary physics courses. The objective of this Frontline is to introduce acoustic levitation in the classroom. This is done with LeviLab, a low-cost and easy-to-use experiment, accompanied by three hands-on procedures (LeviLabs): modifying the cavity length, visually representing standing waves with multiple levitated particles, and a tactile experience by moving a single particle between nodes. The first procedure yields the most accurate speed of sound measurements, while the second and third offer valuable qualitative insights into standing wave properties. This work demonstrates the educational potential of acoustic levitation to investigate sound waves. It aims to make the phenomenon accessible as a learning resource for upper-secondary and undergraduate physics laboratories by providing engaging hands-on experiences for qualitative and quantitative exploration.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"201 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254134","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}

This discrepancy between current school education and our modern scientific understanding has led to calls for the modernisation of the science curriculum. Although there have been attempts to introduce topics of Einsteinian physics (i.e. quantum physics and relativity) to school education, often at the secondary level, we still lack a seamless curriculum in which modern science concepts are gradually introduced in primary and middle schools. Guided by the Model of Educational Reconstruction and following a mixed-methods research design, the Einstein-First project aims to address this gap. Einstein-First has developed and implemented an Einsteinian curriculum from Years 3–10 (students aged 7–16) that resolves the disconnect between science in schools and modern scientific understanding. This paper presents the concepts and rationale for the Einstein-First learning approach, as well as a summary of learning outcomes in six Australian schools with 315 students across Years 3–10. Our generally positive findings lay the foundation for informed curriculum development and school education that provides all students with awareness and appreciation of the fundamental concepts that underpin the technologies of the modern world.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"108 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142254135","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}

As a result, in the academic years 2020/2021 and 2021/2022, students in the second year Electricity and Magnetism courses at the University of Guelph were asked to complete personalized study guides/portfolios as a means of communicating to the instructor what they had learned in the course. Although research has shown that portfolio-style assessment procedures support student achievement at least at the same level as traditional assessment procedures and appear to have additional benefits, they have not been widely adopted in the physical sciences. The goal of this work was to assess some of the affective consequences of using portfolio assessment procedures in an upper-level core physics course. Feedback from students, both in the form of an online anonymous survey as well as a more in-depth, in-person, focus group discussion, was positive. The general consensus was that students found the portfolios to be similar in workload to preparing for a final examination but offered additional benefits such as finding them to be significantly less stressful as well as feeling a greater sense of accomplishment after submission. Learning outcomes of the course were achieved through this approach at similar levels as seen previously, as demonstrated through student performance on the pre- and post-conceptual assessment, and further evidenced by the high-level example problems included here from student submissions. Grades earned on the portfolios were similar to those seen previously with invigilated traditional final examinations. Based on these findings, portfolio assessments will remain a core component of the pedagogical toolbox employed by faculty in physics at the University of Guelph. This project was reviewed by the Research Ethics Board at the University of Guelph for compliance with federal guidelines for research involving human participants. Approval was granted on 11 January 2023, REB # 22–11-004.","PeriodicalId":39773,"journal":{"name":"Physics Education","volume":"100 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142197993","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}
