The Rasch Analysis of Students’ Characteristics in Physics Concept Understanding Improvement through Challenge-Based Learning

Abstract

Concept mastery is one of the main goals in the learning process. This study aimed to analyze the improvement of students’ physics concept mastery by implementing challenge-based learning with Edmodo-assisted learning. This study used mixed methods with an embedded experimental model research design. The research sample was 10th-grade students in a public vocational school’s food crops and horticulture agribusiness program. Data analysis employed the Rasch model with the help of ministeps software version 4.1.1. The results of this study indicate a significant increase in students’ conceptual mastery of +3.44 logit. The average logit value of students’ abilities is higher than the average logit value of the item difficulty level. Students’ physics concept mastery can be improved through the challenge-based learning model assisted by Edmodo.

Analysis of Changes in the Level of Difficulty of Elementary School Students in Learning the RADEC Model on the Concept of Energy Transformation Using the Rasch Model

“…In addition, the skills of students to explain the results of group discussions are still very low, as well as the lack of creativity of students to make a project to achieve the goals of current learning (Aisyah et al, 2023;Novianti et al, 2023;Sukmawati, 2023). According to Aldeya (2019), students can present an idea in another form that is not the same as in the textbook provided they have the capacity to describe concepts (Bohori et al, 2022), identify them, and provide instances or non-examples of them. Therefore, in order to assist students in learning for particular objectives, we need a learning model that can offer a systematic explanation of how to execute learning (Maryana & Sukmawati, 2021;Sukmawati, 2018;Sukmawati et al, 2021b).…”
