Desti Naisella Lalihatu 5th International Scholars Conference Comparative Study towards Junior High School Students Mathematical Problem Solving Enhancement using Three Types Cooperative Learning Model Prepared by Louise M. Saija Desti Naisella Lalihatu 5th International Scholars Conference APIU Thailand, 2017

Problem in Mathematics Learning Mathematical problem solving ability of Indonesian students has not yet been high Factors: Students hardly understand mathematics word problems Not suitable learning approaches or strategies Solving math problems individually 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Solutions Offered Cooperative Learning Types: 1. Students Teams Achievement Division (STAD) 2. Jigsaw 2 3. Teams Games Tournament (TGT) 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Research Method Quantitative research with comparative design Comparative – Partially & Simultaneously 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Samples Junior high school students grade VII 1. SMPN 16 in Surakarta (two classes) 2. UNAI Laboratory School (one class) 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Research Instrument Mathematical problem solving tests - containing six mathematics contextual problems. (Instrument Validity and reliability test done before pretest) 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Findings 2. Partially Comparative Students mathematical problem solving enhancement between Jigsaw 2 and STAD STAD and TGT Jigsaw 2 and TGT DIFFER 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Findings 2. Simultaneously Comparative Table 6 ANOVA students within those three different groups of junior high school students who acquire three different cooperative learning model, STAD, Jigsaw 2 or TGT, averagely have different mathematical problem solving enhancement. 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

Discussion STAD and Jigsaw 2 cooperative learning model implemented strategy was suitable for the students condition The gap between the smart and the lesss intelligent students was wider in the TGT group comparing within the STAD and Jigsaw 2 group of students. Jigsaw cooperative learning considered more effective than TGT (Syahrir, 2011) vs TGT was more effective than Jigsaw towards mathematics learning for students in Klaten (Mirati et al., 2015) 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019

CONCLUSSION Jigsaw 2. STAD and TGT cooperative learning models are effective to enhance students’s mathematical problem solving ability, though the effectiveness are differ one to another Jigsaw 2, STAD and TGT can be used as learning strategy alternatives for teachers in learning mathematics to enhance the problem solving ability of junior high school students 5th International Scholars Conference, APIU - Thailand 2017 09/09/2019
