Pengaruh penggunaan bahan ajar liveworksheets dengan pendekatan saintifik untuk kemampuan pemecahan masalah matematis siswa pada pembelajaran materi statistika SMP

The aim of this research is to examine the effect of using Liveworksheets-based teaching materials in improving mathematical problem solving abilities in statistics material for class VIII junior high school students. The research method used is descriptive qualitative method. The research subjects for this study were class VIII students at SMPN 15 Cimahi consisting of 25 students. The results of this research show that the use of Liveworksheets based teaching materials can improve mathematical problem solving abilities, as evidenced by the average increase in students' mathematical problem solving ability tests before the use of the teaching materials demonstrated, which is equal to 27.20 and after use, teaching materials equivalent to 70.00. Not only that, this study influences students' mathematical problem solving abilities, seen from the results of the t-sample test calculation related to the paired-sample T-test analysis of the two-sided test. The values ​​obtained are tcount = 13,833 and ttable = 1.7109 for a significance level of 5% with df = 24, where 13.833 ≥ 1.7109.
