PENERAPAN PEMBELAJARAN PROBLEM BASED LEARNING BERBANTU VIRTUAL LABORATORY DITINJAU DARI HASIL BELAJAR DAN KEMAMPUAN BERPIKIR LOGIS SISWA SMP

This study was conducted aimed at testing the effectiveness of the Problem Based Learning (PBL) learning model. The subjects of this study were eighth grade students of Muhammadiyah Middle School Aimas, Sorong Regency. The research method used was quasi-experimental. Data collection techniques in this study were observation, tests and questionnaires. The test instrument consisted of learning outcomes tests and students' logical thinking abilities. Questionnaires here contain questionnaires for students' responses to PBL learning using the VR Math application. The results of the study concluded that the experimental class had been given a Problem Based Learning (PBL) model using the VR Math application. The results of the sample obtained the highest learning outcomes scores of learning outcomes 72 and low 56, and the highest logical thinking ability 12 and low scores. 6. The values obtained were analyzed using one mathematical software obtained (1) the significance of 0.447 <0.05 and t count <t table (-0.777 <1.740) so that H0 is accepted and Ha is rejected so PBL learning models using VR Math applications are not effectively reviewed from student learning outcomes. (2) the results of the effectiveness tests of logical thinking abilities obtained a significance of 0,000 <0,05 and t count <t table (-9,160 <1,740) so that the PBL learning model uses the VR Math application effectively in terms of students' logical thinking abilities (3) test significance results Trace Hotteling is obtained sig. 0,000 <0,05 so that the PBL learning model uses the VR Math application effectively in terms of learning outcomes and students' logical thinking abilities.
