Students are introduced to the term wavelength in optics at school level. In this paper, we present an inexpensive and simple method to measure the wavelength of the light of a light emitting diode using a light depending resistor. This experimental set-up is developed at Science Laboratory, Nehru Planetarium (Mumbai), India. It is useful as an…

A central goal of introductory physics for the life sciences (IPLS) is to prepare students to use physics to model and analyze biological situations, a skill of increasing importance for their future studies and careers. Here we report our findings on life science students' ability to carry out a sophisticated biological modeling task at the end…

The "Primary SPACE Project Research Report: Sound" (Watt and Russell, 1990) provides interesting reading relating to primary-aged children's concepts of sound. It reveals a range of children's views on how sound is made, how sounds are heard and how sound travels. While some children are shown to have knowledge that sounds travel and are…

This paper presents improvements made to a computerized adaptive testing (CAT)-based version of the FCI (FCI-CAT) in regards to test security and test efficiency. First, we will discuss measures to enhance test security by controlling for item overexposure, decreasing the risk that respondents may (i) memorize the content of a pretest for use on…

Inquiry-based representation-focused approaches in science education have shown promising outcomes when students engage in knowledge building via an active process of constructing, coordinating, and evaluating representations. To date, much of the existing research around these approaches has taken place in pre-digital classrooms, but the…

The pendulum was an important scientific instrument in the 17th century. It became a typical textbook problem in the 18th century. After the introduction of vectors in physics in the 1890s, the pendulum problem started to be progressively solved in the manner we know nowadays from introductory mechanics courses. Starting from "F = ma"…

The real-time graphing of simple harmonic motion of mass on springs with an Arduino based on an experiment set for teaching and learning physics in high schools where students can learn from real experiences. The objectives of this study are to create and develop a real-time measurement for vertical oscillations of mass on springs using the…

The innovation calls insist on the fact to identify new forms and models of learning and teaching. Actually, the educational approaches that encourage effective learning among student, is the Investigative Approach, which demonstrates more and more its potential in teaching. It is a scientific approach based on questioning and investigation where…

The magnetic field is a more complex and abstract physics subject than other physics subjects, causing students' low ability to solve problems. So there is a need for learning instruments to overcome these problems, especially when online learning during the COVID-19 pandemic. Research creates and implements an online problem-based learning (OPBL)…

This study evaluated the success or failure of using Virtual Workspace (VW) in a projectbased physics laboratory. This study uses a qualitative approach with 4E evaluation methods: educational effectiveness, ease of use, involvement, and environment. Data were collected through a questionnaire to evaluate the implementation and practical functions…

Currently, the physics disciplines are represented by a significantly larger number of professional males, compared to females. Although the problem of underrepresentation of female physicists has several causes, one likely reason is the lower interest that female school students have in physics activities. Several instructional solutions have…

This preliminary study reports upon students' experiences in engaging friends and family members in discussing global climate change for required assignments in a laboratory-centered physics course for prospective elementary and middle school teachers, (https://open.oregonstate.education/physicsforteachers). Research questions included: What…

Lately, new materialism has been proposed as a theoretical framework to better understand material-dialogic relationships in learning, and concurrently network analysis has emerged as a method in science education research. This paper explores how to include materiality in network analysis and reports the development of a method to construct…

Understanding how physicists solve problems can guide the development of methods that help students learn and improve at solving complex problems. Leveraging the framework of cognitive task analysis, we conducted semistructured interviews with theoretical physicists (N=11) to gain insight into the cognitive processes and skills that they use in…

This study investigated the effects of providing domain information in an early stage of an inquiry process, together with an aligned hypothesis scratchpad, on inquiry learning, and hypothesis generation in particular. Participants were provided with basic domain information that was adapted to their prior knowledge (experimental condition) or…
