STAD DAN PAPAN BILANGAN: INOVASI PEMBELAJARAN MATEMATIKA DI SDN 02 KANIGORO

Abstract

Mathematics learning in elementary school requires a learning experience that enable students to understand abstract concepts through concrete and meaningful activities. The initial condition in grade II students of SDN 02 Kanigoro showed that students experienced difficulties in understanding the concept of place values, especially tens and units. This study aims to describe the application of a cooperative learning model of the Student Teams-Achievement Divisions (STAD) type combined with number board media and to increase the understanding of the concept of student place values. This study uses Classroom Action Research (PTK) which is carried out in two cycles with stages of planning, implementation, observation, and reflection. The research subjects are 24 grade II students. Data was collected through observation, tests, and documentation. Data analysis was carried out descriptively by calculating the average score and percentage of learning completeness. The results showed an increase in the average score from 65.63 in the pre-cycle to 69.13 in the first cycle and 90.96 in the second cycle. The completeness of learning also increased, namely 10 students (42%) in the pre-cycle, 8 students (33%) in the first cycle, and 23 students (96%) in the second cycle. Students' learning activities also developed from cycle I to cycle II. The increase was supported by the improvement of number board media through pasting and counting pictures. The results showed that the combination of STAD and number board media can create more active, concrete, and collaborative mathematics learning and support the understanding of the concept of the value of students'places.
