Abstract


This study aims to describe the effectiveness of the Treffinger learning model assisted by a web authoring platform on the mathematical problem-solving abilities of grade VII junior high school students on algebraic form material. The method used in this study is an experiment with a pre-experimental design with a One Group Pretest-Posttest Design. The research instrument is a mathematical problem-solving ability test given before and after treatment. The results of data analysis using the paired sample t-test showed that the thitung value of -12.416 is smaller than the -ttable of -1.725 and the p-value of 0.001 <0.05. This shows that there is a significant difference between the pretest and posttest results, which means that the Treffinger model assisted by Google Sites has an effect on improving students' mathematical problem-solving abilities. The average pretest score of 43.429 increased to 74.143 in the posttest, showing an increase of 30.714%. This study shows that the application of the Treffinger learning model assisted by Google Sites can be an effective alternative in mathematics learning to improve students' problem-solving abilities.
