Improving Motivation and the Decimal Computation Skill by Using Manipulatives in Thematic-Integrated Learning in Elementary School

Abstract

This study aims to: (1) determine whether teacher’s performance in teaching using manipulatives media are in good classification to support arithmetic skills and students’ learning motivation (2) increase the learning motivation, and (3) increase the decimal computation skill of class IV B students of SDN 15 Ulu Gadut, Padang by using manipulatives. The results are as follows: (1) the teacher’s teaching performance is in a good category with a total score of cycles I, II, and III, 160.5, 174, and 179.17 respectively. (2) the students’ learning motivation has increased by 62.04 in cycle I, 65.56 in cycle II, and 68.16 in cycle III and then, the result of students’ motivation scale test is in a very high category, with an average increase of 79.41, 85.05, and 87.05 in cycles I, II, III. (3) the results of arithmetic skill test at the end of the third cycle are at an average score of 90.81 at level I, 93.51 at level II, 75.14 at level III, 75.68 at level IV, and 76.76 at level V.
