Abstract
This research is a quasi-experimental study (quasi-experimental) with post-test only control group design, aiming to find out whether students^ ability to operate algebraic forms taught using creative problem solving (CPS) learning models with the help of geometric props is better than conventional learning models. The population of this research is the students of class VII SMP in the academic year 2014/2015 which consists of 15 classes. The sample was determined by cluster random sampling technique and obtained class VII.5 and VII.14 as the experimental class while class VII.7 and VII.15 as the control class. Data on students^ ability to operate algebraic forms were collected using an algebraic operation ability test. From the test results, the average score of the operational ability of the experimental class students was 74.48, while the average score of the control class^s algebraic form of operation ability was 72.44. These results were analyzed by t-test at a significance level of 5% and obtained tcount of 1.714. From the calculation of SPSS 16.0 for Windows obtained significance = 0.089 (because of the 1-sided test then 0.089: 2 = 0.0445). If the significance level is = 0.05, then the value of sig. (0.0445) is much smaller than the value of. Therefore, it can be concluded that the creative problem solving (CPS) learning model with the help of geometric props has a very positive effect on students^ ability to operate algebraic forms.
