Abstract

This research aims to determine the effectiveness comparison between the open ended, ELPSA, and problem solving approach, with the STAD type cooperative model in learning SPLDV material in class VIII of SMP Negeri 2 Sungguminasa.This type of research is quantitative research. The design of this study is a quasi experimental design in the form of nonequivalent pretest-posttest comparison group design. The population in this study were all students of class VIII of SMP Negeri 2 Sungguminasa consisting of 11 classes and the sample was determined using the double random sampling cluster technique, 3 classes of experiments will be selected, all students in the three classes are the samples in this study. The instruments in this study were (1) observation sheet of learning implementation, (2) mathematics achievement test, (3) teaching material, (4) student observation sheet, and (5) student response questionnaire. Data analysis techniques used in this study are descriptive statistical analysis and inferential statistical analysis.
Descriptive analysis results show that: (1) the application of the open ended approach is effective in learning SPLDV material- (2) application of the ELPSA approach is effective in learning SPLDV material- (3) the application of an effective problem solving approach in learning SPLDV material- (4) the results of the comparative effectiveness respectively are the ELPSA approach, the open ended approach, and the problem solving approach, with the STAD type cooperative model.
One way ANOVA test results at 95% confidence level showed that: (1) there were no significant differences in the learning outcomes of SPLDV students, (2) there were no significant differences in student activity, and (3) there were no differences in students^ responses significantly. Thus, inferential there is no significant difference from the application of the open ended approach, ELPSA, and problem solving, with the STAD type cooperative model in learning SPLDV material

Keywords: Comparison, Effectiveness, Open Ended approach, ELPSA approach, Problem Solving Approach, and STAD Type Cooperative Model
