Application of Creative Problem Solving Learning Model to Problem Solving Ability in Chemistry Material
This study aims to determine the effect of applying creative problem solving (CPS) learning models on students problem solving abilities in chemistry on acid-base material. This study uses a quasi experimental research design with a pretest-posttest control group design. The population of this study was class XI MA As adiyah Tolai Parigi Moutong Regency as many as 2 classes consisting of 44 students. The sampling technique in this study was saturated sampling, so class XI A was the control class and XI B was the experimental class, each of which consisted of 22 students. Data collection using a problem solving ability test instrument. The results showed that the level of problem solving ability in the control class using conventional learning models obtained an average value of 70 while the experimental class using creative problem solving learning models obtained an average value of 82. Analysis of each indicator of problem solving ability showed that students had able to understand the problem, plan problem solving, and carry out the solution plan well. However, students have not been able to re examine the results of problem solving properly. The analysis of hypothesis testing using t test shows that the value of sig-(2-tailed) obtained is 0,004 less than 0,05 so that it shows the effect of applying creative problem solving (CPS) learning models on students problem solving abilities in acid-base material.
