Abstract

The aim of this study is to analyze the influence of collaborative problem solving on the enhancement of mathematical proportional reasoning ability. The problems underlying this study include the proportional reasoning ability of students is still low so innovation in learning that can develop students' proportional reasoning abilities. The method used is quasi-experiment with non-equivalent control group design. The sampling technique is purposive sampling. Quantitative analysis was performed by calculating the N-gain using the normality test, and t-test. Research results of this study are (1) The enhancement of mathematical proportional reasoning ability of students who received collaborative problem solving is better than students who received conventional learning, (2) There is difference of mathematical proportional reasoning ability of students who received collaborative problem solving and students who received conventional learning, (3) The average of N-gain proportional reasoning ability are 0.33 in the experimental class and 0.22 in the control class.
