Development of Understanding the Concept of Opportunity Through Kulibia Game with Teaching at the Right Level (TaRL) Approach

Learning mathematics with a mechanistic approach results in being difficult for students to understand. Opportunity, as one of the mathematics contents, requires a learning process, which involves hands-on activities in teaching. Students were grouped according to their abilities based on the differences in students’ understanding through diagnostic assessment in the concept of differentiated learning, and through differentiation of content. Teaching at the right level (TaRL) is a differentiated learning technique, considered appropriate, to be applied in an effort to control student activities by utilizing Kulibia media as a learning context. Kulibia is one of the marine biota usually found by people on the coast and is used as one of the traditional games for children in Maluku. Through this game, students’ understanding of the concept of chance can be developed. The participants of this study were 8th grade students in Phase D, a total of 28 students. The data analysis technique used was one sample mean difference test. The results of data analysis prove that H0 is accepted meaning that the average understanding of the concept of chance exceeds the minimum completeness criteria of 70. Analysis of understanding shows that high-group students have a better understanding than students in other groups. Keywords: comprehension, Kulibia, TaRL, differentiated learning
