<![CDATA[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.]]>
