Abstract

Graphic interpretation is as critical in physics education as problem-solving. However, we know that today's classes focus more on problem-solving. This study uses a survey to determine college students' graphic interpretation skills. The study consists of two phases. The first phase includes the development and statistical analysis of the survey. The second phase includes comparing and discussing the data resulting from the application of the developed survey. The research data were analyzed using both exploratory factor analysis and confirmatory factor analysis techniques. The survey on graphic interpretation skills, including the understanding and analysis processes, consisted of 17 items based on analysis results. The survey data were collected using purposive sampling from 113 college volunteers during the fall semester of 2022-2023 at Dokuz Eylul University in Turkey. The participants consisted of 57 geoscience students and 56 mining students. The survey results showed that the kinematic interpretation skills of mining engineering students were higher than those of geoscience students. These differences between geoscience and mining engineering students in cognitive, affective, and psychomotor behaviors were discussed.

Abstract

The study investigated the effects of a combination of Peer Discussion and Isomorphic Problems (PD-IPs) on high school students' graph understanding and conceptual learning. The study was conducted on kinematics and Newton’s Laws of Motion with 67 high school students from two groups. The experimental group (EG) consisted of 34 students, while the control group (CG) combined with 33 students. The students in EG were taught using the PD-IPs approach, while those in CG were taught using the traditional method. The research data were collected using the Force Motion Achievement Test (FMAT), which was composed by selecting multiple-choice questions from some standardized tests (Force Concept Inventory, Mechanic Baseline Test, Test of Understanding Graphs in Kinematics). The FMAT includes 25 multiple-choice questions. 11 were related to graph understanding, and the rest were related to conceptual learning. The research showed that the PD-IPs approach had a more positive effect on students' understanding of graphs and conceptual learning than the traditional teaching method. The findings indicate that implementing the PD-IPs approach requires minimal effort while demonstrating the potential to evaluate and improve high school student's academic performance in physics education.
