THE EFFECTS OF ORGANIZING MATHEMATICS LEARNING ACTIVITES ON RATIO, PROPORTION AND PERCENTAGE BASED ON CONSTRUCTIVIST THEORY WITH COOPERATIVE LEARNING TECHNIQUE (TAI) FOR THE STUDENTS IN SEVENTH GRADE

Abstract

The aims of this quasi-experimental research were 1) to study the effects of organizing mathematics learning activities for efficiency learning results according to E1/E2. 2) to compare the learning achievement before and after using the organizing mathematics learning activities and 3) to study the satisfaction of students towards organizing mathematics learning activities, on ratio, proportion and percentage based on Constructivist theory with cooperative learning technique TAI for the Students in Seventh Grade. The research samples were 33 Students in Seventh Grade in academic year 2019. The researchers used clustered random sampling in this research.

In addition, the research instruments were (1) organizing learning activities plan, which efficiency level was at 0.95. (2) Learning achievement test, which confidence interval level, difficulty level, and discrimination level was 0.899, 0.49-0.80 and 0.25-0.70 respectively. (3) the satisfaction of students towards organizing learning activities assessment form, which the reliability of Cronbach alpha coefficient was 1.00. The data analyzed by mean, percentage, standard deviation, t-test dependent

Lastly, the findings of the study were (1) the efficiency level of effects of organizing mathematics learning activities was at 85.60/86.36 which met the efficiency criteria according to E1/E2. (2) the learning achievement results after learning activities was higher than before organizing the activities, which statistical significance level was at .05. (3) the satisfaction level of students towards organizing Mathematics learning activities in general was 96.36 percent that means the student's satisfaction was at high to highest level.
