The Effectiveness of the Treffinger Learning Model Assisted by a Web Authoring Platform on Students' Mathematical Problem-Solving Ability

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
