In the context of quantum mechanics, students are often asked to use delta functions to solve problems. Here, we investigate three typical problem-solving processes using delta functions: a delta function potential well problem, a position space delta function problem, and a momentum space delta function problem. We studied students'solutions in…

Many statistical methods (estimators) are available for estimating the consensus value (or average effect) and heterogeneity variance in interlaboratory studies or meta-analyses. These estimators are all valid because they are developed from or supported by certain statistical principles. However, no estimator can be perfect and must have error or…

This study proposes an online practicum model supported by Wireless Sensor Network (WSN) to implement a physics practicum after the COVID-19 Pandemic. This system is guided by exploratory inquiry questions to help structure students' mindsets in answering investigative questions. Online practicum is also integrated with video conferencing, chat,…

Old physics textbooks give us a great opportunity to learn about the history of science and rediscover different methods to teach physics to our students. There are many disused and forgotten experiments in them, but these can still be very useful to affirm and understand physics. This is the case of an instrument used in the 19th century to…

Physics is criticized for a strong disciplinary culture that many students struggle to identify with. This study uses 12 longitudinal interviews with four high-achieving students in Norway, following them from secondary physics and into university science, technology, engineering, and mathematics (STEM) studies, exploring how they perform their…

This article describes the design and evaluation of an online, asynchronous tool that mirrors the beneficial peer instruction process currently conducted in face-to-face classrooms. In the online Peer Instruction tool, students respond to a multiple-choice question with an answer and explanation. They are then exposed to peer responses to the same…

Since the beginning of the 21st century, the appropriation of the sociocultural perspective by the physics education research community has represented a linguistic turn in the field, pointing out a promising path to overcome the dominance of the "individual paradigm," both in terms of student learning and initial and continuing teacher…

Thermodynamic processes are often presented in so called P-V diagrams and the processes are often isobaric, isochoric, isothermal, and adiabatic. The purpose of the qualitative research reported here was to explore students' reasoning and interpretation of P-V diagrams that were presented by the help of GeoGebra. The research group had 15 students…

Sensory over-responsivity in the vestibular domain (aka gravitational insecurity) has been frequently identified in the literature. However, little has been written about the effectiveness of interventions, especially in toddlers with these idiopathic challenges (e.g. without a diagnosis of autism). The objective of this pilot study was to test…

Inquiry-based learning is a learning-and-teaching approach that allows students to gather and build knowledge of scientific facts by asking questions. To gain an understanding of the impact of such an instruction, this study examines the effectiveness of Video Inquiry-based Cooperative Learning (VICL) and Video Inquiry-based Learning (VIL) on…

Physics homework often boils down to solving end-of-chapter quantitative problems. For targeting different learning goals of physics education, different types of homework are needed. The aim of this research was to compare the effectiveness of simulation-based, video-based, and paper-and-pencil homework in developing an understanding about…

In light of recent efforts to increase the diversity of the physics workforce, the need to counter the long-term marginalisation of students of colour from physics has received more attention. Culturally relevant pedagogy (CRP) is a multicultural approach to teaching and learning designed to attend to students' culture as starting points toward…

The Peer Assisted Learning (PAL) program at Sacramento State was established in 2012 with one section supporting introductory chemistry. The program now serves 17 courses with high rates of students who receive a D or an F or withdraw (DFW) from the course in biology, chemistry, mathematics, physics, and statistics; the program enrolls…

Collaborative learning with peers can lead to students learning from each other and solving physics problems correctly not only in situations in which one student knows how to solve the problems but also when none of the students can solve the problems alone. We define the rate of construction as the percentage of groups collaborating on problem…

[This paper is part of the Focused Collection on Instructional labs: Improving traditions and new directions.] In this paper, we describe the results of a research project whose goals were to (1) develop and implement video-based experimental investigations using the Investigative Science Learning Environment (ISLE) approach and (2) study how…
