THE DISCREPANCY OF THE STUDENTS’ MATHS ACHIEVEMENT BASED ON THE COMBINATION OF COOPERATIVE LEARNING MODEL, STUDENTS’ CHARACTERS BEHAVIOUR, AND EDUCATION LEVEL (EXPERIMENTAL STUDY ON THE STUDENTS OF SENIOR AND JUNIOR HIGH SCHOOLS IN KENDARI)

This 3x3x2 factorial - designed experimental study aims at analysing the discrepancy of students' Maths achievement based on the combination of cooperative learning model (Jigsaw - STAD, TSTS - STAD and STAD), the students' character behaviours (low, moderate, high), and the education level (public junior and senior high schools) in Kendari, southeast Sulawesi province in 2016 with 450 students as the sample. A program package of EViews - 7 is used to analyze the six types of discrepancy results as follows: (i) type 1 accepts null hypothesis, (ii) type 2 rejects null hypothesis, (iii) type 3 rejects null hypothesis, (iv) type 4 accepts null hypothhesis, (v) type 5 accepts null hypothesis, and (vi) type 6 accepts null hypothesis. Accepting null hypothesis means that the average score of students' Maths achievement between experiment and control class does not have any significant difference, while rejecting null hypothesis refers to the definition that the average score between control and experiment class is significantly different.
