Pemahaman Konsep Matematika Menggunakan Model Pembelajaran Problem Based Learning Dan Group Investigation

Abstract

<p class="Els-keywords">The purpose of this research is to determine whether there are differences in the understanding of the concept of students who learn by applying the model Problem Based Learning with Group Investigation. This research in to the type of quasi-experimental design of non-equivalent pretest-posttest control group. The samples taken were class XI IPA 2 (experimental class I) and class XI IPA 3 (experimental class II). The instrument applied was a learning outcome test containing 5 items. Data analysis was calculated using analysis techniques: descriptive and inferential. The results of the descriptive data obtained mean scores of 44.81 pretest and 76.54 posttest for the experimental class I, while the experimental class II scored 47.54 pretest and 84.14 posttest. From the independent sample test, it was obtained a sign score: 0.000 at a significance level of 5%. This means that H<sub>0 </sub>is rejected, so it was decided that the level of conceptual understanding for the model is Problem Based Learning different from the level of concept understanding in the model Group Investigation.</p>

Pengaruh Model Pembelajaran Group Investigation terhadap Kemampuan Pemecahan Masalah Matematis Berdasarkan Self Confidence Siswa SMP/MTs

“…Siregar dalam Fatimah et al (2021) menemukan bahwa pembelajaran kooperatif atau berkelompok Group Investigation tidak hanya membantu siswa dalam menciptakan kemampuan bekerja sama, berfikir kritis, dan bersosialisai, tetapi juga membantu siswa dalam menemukan ide. Menurut Natsir and Taufik (2020), pelaksanaan pembelajaran dengan menerapkan model pembelajaran group ivestigation dapat memberikan kenyamanan bagi siswa dan dalam suasana dan aktivitas belajar dalam segala bentuk pengalaman belajar yang memberikan kesempatan bagi siswa untuk mendapatkan informasi yang berhubungan dengan kenyataan atau gagasan dari pokok bahasan/isu yang dibahas.…”

Using Problem-Based Learning to Improve 12th Grade Students’ Learning Outcome of Mathematical Three-Dimension

“…Problem-based Learning (PBL) is an approach in education that means helping students find real problems, collect information with self-determined strategies and make decisions (Timor et al, 2021). PBL helps learners improve their skills in terms of critical thinking and solving problems (Fatimah et al, 2021).…”

“…The Problem-based Learning (PBL) learning model is superior to conventional in the aspect of shiva's critical thinking skills. PBL also changes students' interest and learning achievement for the better (Mashuri et al, 2019), because problem-based learning is an approach in education that means helping students find real problems, gather information with self-determined strategies and make decisions (Fatimah et al, 2021).…”
