In this work we present the application of design based research (DBR) methodology to conduct a systematic iterative study of the design and implementation of a teaching-learning sequence (TLS) on emf (electromotive force). This work is the final part of a broader study that started with the analysis of students' difficulties with emf in the…

The present work explores students' repertoire of explicit knowledge fragments relevant to the atomic structure, seeking to answer which of those and through which routes are activated by students when constructing their explanations for some everyday situations. For this purpose, six tasks describing different situations were given to 225…

Scientific expertise is manifested through extensive cycles of making and acting on decisions. To learn the processes and practices of science, therefore, students must have practice with scientific decision making. We argue that this can only happen if students are afforded agency: the opportunity to make decisions to pursue a goal. In this…

Light has the most interesting phenomena among physics concepts. We designed the light phenomena conceptual assessment (LPCA) to help teachers measure their students' conceptual understanding of light phenomena. We expected to measure increases in student understanding of light phenomena after learning about the wave and particle nature of light…

Learning physics at SMA, does not only involve memorizing facts, but it also engages the students in solving more problems without delay and attaining a real learning achievement. This study aimed to analyze the effect of project-based learning (PjBL) compared with direct instruction (DI) and student procrastination on student cognitive…

Electric potential is one of the most challenging concepts taught in high school physics classes due to the abstract nature of the concept. When taught, electric potential is often taught using a poorly triangulated set of instructional analogies, each possessing different strengths and limitations. Within this paper we share our learning from a…

I am a parent first and foremost, but I am also an educator. What does one role have to do with the other? I realized that the different identities that make me who I am are not independent of each other during the process of formulating my teaching philosophy. Realizing the link between the different identities in my life influenced my teaching…

As targeted, single-conception curriculum research becomes more prevalent in physics education research (PER), the need for a more sophisticated statistical understanding of the conceptual surveys used becomes apparent. Previously, the factor structure of the Force Concept Inventory (FCI) was examined using exploratory factor analysis (EFA) and…

We elaborate on a new approach of assessing content-based epistemic clarity of college physics students in terms of their ability to discriminate between different epistemic warrants for propositions in a chained argument in physics. A threefold classification (nominal, physical, and mathematical) of warrants is used, with each class split into a…

The objective of this study is to design a temperature measurement system based on a non-contact method using a sensor camera from a webcam. The material being measured is nickel wire given an electrical current of 4.5 A-6.5 A with an interval of 0.5 A. The temperature measurement is based upon the measurement of the average pixel value…

Systematic research on physics teacher education (PTE) programs in the United States is rare, owing both to the great variety of practices and structures enacted by U.S. PTE programs and to the lack of measurement tools available to measure what successful PTE programs do. To help meet the need for a specific, objective, and reliable guide for…

The concepts of the Coriolis and the centrifugal force are essential in various scientific fields and they are standard components of introductory physics lectures. In this paper, we explore how students understand and apply concepts of rotating frames of reference in the context of an example lecture demonstration experiment. We found in a…

Many instructional physics labs are shifting to teach experimentation skills, rather than to demonstrate or confirm canonical physics phenomena. Our previous work found that many students engage in questionable research practices in attempts to confirm the canonical physics phenomena, even when confirmation is explicitly not the goal of the lab.…

The paper examined gender difference in the Scholastic Achievement Test (SAT) among senior secondary school adolescents using the physical science of physics in three (3) separate papers. The paper attempted to ascertain whether gender difference accounts for the score differential observed in the Scholastic Achievement Test (SAT). The study…

The paper is focused on the investigation of impact of created experimental natural scientific programme for preschool-age children. Our programme concentrates on physics teaching adapted for preschool age in which children have possibilities to make experiments themselves--empirical cognition. Its innovation with respect to other stimulation…
