The Influence Of Two Stay Two Stray (TS-TS) Cooperative Model On Problem Solving Ability

The purpose of this research is to know whether there is an influence of cooperative model type Two Stay Two Stray (TS-TS) on problem-solving abilities on the subject of ecosystem class VII at junior high school. This type of research is Quasi-Experimental Design research. The technique of collecting data using a test, test in the form of description is 7 problem. Data analysis techniques to see problem-solving ability using normality test, homogeneity test, and t-test (t-test). The result of this research is the average value of post-test in the experimental class 73,71 and the control class 60,86, for the mean value per indicator that is in the experimental class of the indicator understand the problem (49,71), prepare the problem-solving plan (11.80) and implementing a problem-solving plan (12,19). While in the control class the indicator understands the problem (36,43), prepares the problem-solving plan (11,38), and implements the problem-solving plan (13,04). To test the hypothesis obtained t-count (4,5395)> t-table (1.6801). Thus there is influence of Two Stay Two Stray (TS-TS) cooperative model on problem-solving ability on VII classroom SMPN 2 Sembalun Bumbung Academic Year 2016/2017.
