EFFECTIVENESS COMPARISON BETWEEN COOPERATIVE MODELS WITH NUMBERED-HEADS-TOGETHER AND TEAM ASSISTED INDIVIDUALIZATION IN GEOMETRY

Abstract

This is an experiment research aims to describe (1) implementation of cooperative learning model type Numbered-Heads-Together (NHT) and Team Assisted Individualization (TAI), (2) effectiveness of TAI based on three aspects: students’ learning outcomes, students’ activities, and students’ responses, (3) effectiveness of NHT based on onthree aspects: students’ learning outcomes, students’ activities, and students’ responses; and (4) comparison of the effectiveness of NHT and TAI. Two classes were selected from six classes in grade VII (Junior level)of SMP Negeri 2 Bua. One class used TAI and another used NHT. The effectiveness based on three aspects:students’ learning outcomes, students’ activities, and students’ responses. The results showed that: (1) The implementation of TAI is in high level with the average 3.60. (2) The implementation of TAI is effective in terms of the three aspects: (a) the learning outcomes of students with an average post-test score is greater than the average score of pretest, posttest score average is 79,47≥ KKM (standard score), and the percentage of students who completed is 88.89% ≥ 85%; (b) the students learning activities with an average of 3.24; and (c) the students’ responses with an average of 3.57 (positive category). (3) The implementation of NHT is inhighcategory with an average of 3.69. (4) The implementation of NHT is effective in terms of three aspects: (a) the students’ learning outcomes with an average post-test score greater than average score pretest, posttest score average is 78,64≥KKM (standard score), and the percentage of students who passed the score is 86.11% ≥ 85%; (b) the students learning activities with an average of 3.11; and (c) the students’ responses with an average of 3.46. (5) Based on the three aspects of effectiveness, it derives that the implementation of TAI is more effective than the type NHT.
