Pengaruh Penerapan Model Pembelajaran Example non Example terhadap Kemampuan Pemecahan Masalah Matematis Siswa

The problems studied in this study are related to the less than optimal achievement of students' mathematical problem-solving abilities. The purpose of this study was to determine the effect of the Example non Example learning model on the mathematical problem-solving abilities of class VIII students in the Even Semester of SMP Negeri 19 Bandar Lampung in the 2024/2025 Academic Year. This study used an experimental method with the population in this study being all class VIII students of SMP Negeri 19 Bandar Lampung consisting of 7 classes. While the sample was taken from two classes, namely class VIII B as the experimental class that applies the Example non Example learning model, and class VIII C as the control class that applies the conventional learning model. The sample was taken using the Cluster Random Sampling technique. To determine students' mathematical problem-solving abilities, the author conducted a test in the form of five essay questions that had previously been tested for validity and reliability. Hypothesis testing in this study used the t-hit formula and obtained t = 3,29. From the t-distribution table at a significance level of 5%, it is known that t = 1,67, so , which means that the average mathematical problem-solving ability of students using the Example non Example learning model is higher than the average mathematical problem-solving ability of students using the conventional learning model.
