<![CDATA[This study aims to determine the effect of the Treffinger Learning Model in terms of students' problem-solving abilities on flat geometry materials assisted by Wizer.me at SMP Negeri 2 Nibung Hangus. The research method is quasi-experimental research. Based on the results of data analysis and discussion that have been carried out regarding the application of the Treffingger learning model assisted by wizer.me on students' problem-solving abilities, it was obtained that the t-test results obtained t_(count)> t_(table) (3.037>1.669) then H (0) was rejected and H (1) was accepted. So it can be concluded that there is an influence of the Treffingger learning model assisted by wizer.me on students' problem-solving abilities. This means that the problem-solving abilities of students who are taught using the Treffingger learning model using the help of wizer.me are better than the problem-solving abilities of students who are taught using conventional learning models.]]>
