This study aims to develop a structured scaffolding-guided inquiry (SSGI) learning model that is oriented toward nurturing argumentation skills to solve complex problems. Test the effectiveness of the SSGI model in improving students' argumentation skills to solve complex problems. This research is development research that refers to Dick and…

In this paper, we demonstrate the fruitfulness of a theoretical framework called "Commognition," developed in the context of mathematics education research, for conceptualizing and analyzing a professional development (PD) process on measurement uncertainty for secondary physics teachers. Evaluating measurement uncertainty is an…

This research is a type of descriptive research with a quantitative approach, with sampling using cluster sampling technique. The purpose of this research is to see the ability of prospective physics teachers in preparing TPACK-based learning tools. The results obtained on the ability of Content Knowledge (CK) were at a score of 52.66 in the…

Reforming the professionalization experiences of future faculty members, including their undergraduate experience, provides a possible means to create scalable change in higher education. However, this requires an understanding of where faculty undergraduate training occurs. We analyze data from 7748 tenure-line faculty members across 611 U.S.…

Doctoral qualifying exams are considered essential in assessing a student's readiness for research and advanced studies. Despite their significant role in many physics programs, questions have been raised about their format, execution, and relevance. Our research investigates perceptions held by faculty members regarding the graduate doctoral…

In this article, we describe a study in which a validated motivational survey was used to investigate the effect of working in mixed or same-gender groups on physics self-efficacy and self-reported peer influence on self-efficacy in a calculus-based introductory physics course in which women are severely underrepresented both in our sample and in…

The implementation of California Assembly Bill (CAB) 705 has impacted how students enroll into Physics courses. This paralleled anecdotal evidence of a decline in student mathematical abilities. The goal of this research study was to determine the existence of a relationship between CAB 705 and student success in specific Physics courses. This…

The field of geometrical optics features a broad knowledge base concerning conceptual learning difficulties and student conceptions. However, in contrast to other areas of physics, no widely used standard test instrument exists to assess middle school students' conceptual knowledge of geometrical optics. This is even more true for other areas of…

Chemical bonding is central to explaining many phenomena. Research in chemical education and the Framework for K-12 Science Education (the "Framework") argue for new approaches to learning chemical bonding grounded in (1) using ideas of the balance of electric forces and energy minimization to explain bond formation, (2) using learning…

There is an ongoing challenge with STEM education: making physics, math, and science, in general, interesting, understandable, and retentive for college science and non-science majors, K-12 students, and the public. If not imparting detailed knowledge, at least one would like to introduce important concepts that will be remembered, appreciated,…

Science education researchers typically face a trade-off between more quantitatively oriented confirmatory testing of hypotheses, or more qualitatively oriented exploration of novel hypotheses. More recently, open-ended, constructed response items were used to combine both approaches and advance assessment of complex science-related skills and…

Self-Regulated Learning (SRL) is important to solve learning problems. This research aimed to determine the effect of the problem-solving based Self-Regulated Learning (SRL) strategy on simple harmonic motion material toward the metacognitive abilities of student's senior high school. This research applied a quasi-experimental method with a…

We have developed a stereo vision system for observing real objects for experimental physics demonstration. The stereo vision observes objects from two different points of view. An observer can identify the distance and velocity of an object based on at least two different points of view. This paper demonstrates our comprehensive observation in a…

This paper reports on topic-specific pedagogical content knowledge (PCK) enacted by three pre-service science teachers during their final year school-based internship. An interpretive, qualitative case study was conducted to investigate to what extent the pre-service teachers applied the knowledge taught during a preceding physical science method…

Since the vibration of a single pendulum is very periodic, measuring its period is a very interesting topic. When students are asked to measure the period of a single vibration, they start and stop the stopwatch when the pendulum reaches the top point as a reference point. In this paper, we try to show that the error can be reduced more by using…
