Pengaruh model discovery learning terhadap hasil belajar siswa pada materi tabung di SMP negeri 1 panyabungan

This research aims to see the influence of the discovery learning model on students' mathematics learning outcomes in tube material in class IX. Quasi experimental design. The post-test control group used by researchers uses a quantitative approach. All students in class IX of SMPN 1 Panyabungan are the population of the research, while the sample consists of two classes, namely classes IX-1 and IX-2, each class consists of 22 students selected using purposive sampling techniques. The research instrument used was a learning outcomes test in the form of a final test (post-test), which consisted of 8 essay questions. Data analysis techniques include a normality test to ensure that the data is normally distributed, a homogeneity test to check the equality of variance between groups, and hypothesis testing using the t-test to determine the significance of differences in learning outcomes between the experimental and control groups. The results of the data analysis process obtained show that the calculated t-value is 9.706, which is higher than t-table value of 2.018 at the 5% significance level. This shows that the discovery learning model influences student learning outcomes in class IX curved-sided geometric shapes (tube) material at SMP Negeri 1 Panyabungan.
