Abstract

Penelitian ini bertujuan untuk mendeskripsikan: 1) validitas perangkat pembelajaran berorientasi model pembelajaran berbasis masalah yang dikembangkan, 2)  kepraktisan perangkat pembelajaran berorientasi model pembelajaran berbasis masalah yang dikembangkan, 3) keefektifan perangkat pembelajaran berorientasi model pembelajaran berbasis masalah yang dikembangkan, 4) peningkatan kemampuan komunikasi matematis siswa dengan menggunakan perangkat pembelajaran berorientasi model pembelajaran berbasis masalah yang dikembangkan, 5) peningkatan self-efficacy dengan menggunakan perangkat pembelajaran berorientasi model pembelajaran berbasis masalah yang dikembangkan, 6) mengidentifikasi proses jawaban siswa dengan menggunakan perangkat pembelajaran berbasis masalah yang telah dikembangkan. Penelitian ini merupakan penelitian pengembangan (research and development), produk yang dihasilkan adalah rencana pelaksanaan pembelajaran, lembar aktivitas siswa, buku petunjuk guru, dan buku siswa.Pengembangan perangkat pembelajaran berorientasi model pembelajaran berbasis masalah dikembangkan dengan menggunakan model pengembangan Four-D dengan 4 tahap yaitu: define, design, develop dan disseminate. Subjek dalam penelitian ini adalah siswa kelas VIII-A dan VIII-B di SMP Islam Terpadu Nurul ‘Azizi  Medan. Dari hasil ujicoba I dan ujicoba II diperoleh:1) perangkat pembelajaran yang dikembangkan memenuhi kriteria valid, baik dalam validitas isi maupun validitas konstruk. 2) perangkat pembelajaran yang dikembangkan memenuhi kriteria praktis, 3) perangkat pembelajaran yang dikembangkan memenuhi criteria efektif, 4) terdapat peningkatan kemampuan komunikasi matematis siswa menggunakan perangkat pembelajaran yang dikembangkan, 5) terdapat peningkatan self-efficacy siswa menggunakan perangkat pembelajaran yang dikembangkan, 6) proses jawaban pada ujicoba II lebih banyak memperoleh kriteria penilaian “baik”. Proses jawaban siswa pada ujicoba II lebih terstruktur, sistematis, serta sesuai dengan indikator kemampuan komunikasi matematis.Kata Kunci: Model Pembelajaran, Pembelajaran Berbasis Masalah, Model Four-D Thiagarajan,   Kemampuan Komunikasi Matematis, Self-Efficacy

Abstract

 This study goals to determine the implementation of science-technology-society (STS) based on collaborative with mind mapping media to improve students' creative thinking on hidrocarbon material. The sampling technique used was using Pre-experimental Design (Nondesign) in the form of a one-group pre-test-post-test design in class XI MIPA 1 as an experimental class taught using a collaborative-based learning model using a mind map. media. The analysis technique used is the average difference test, the percentage increase in learning outcomes, normality test, and hypothesis testing. The results obtained from the average value of the pretest data before the treatment is given in the experimental class is 49.83 while post-test data after treatment in the experimental class is 77.66, the gain results also show a value of 0.543 which means it can meet the standard of determination value with creative abilities. developed are 2 indicators. students) was 69%.

Abstract

Differences in student learning styles as part of individual characteristics that cause differences in student learning outcomes need to be considered in the learning process. This study aims to analyze the differences in the learning styles of high achieving students and students with scores below the KKM. This research is a qualitative research with a sample of 50 students of SMA Negeri 1 Aek Natas. Data collection techniques were carried out by giving questionnaires, interviews, and observation. Data analysis techniques were carried out using the Miles and Huberman methods. The results showed that for a visual learning style tendency of 28, students with a kinesthetic learning style tendency of 14, and students with an auditory learning tendency of 8. The learning style of achieving students with ratings 1-3 dominates the auditory where students prefer discussion and active in giving opinions to friends and teachers. The learning styles of students with grades below the KKM are all three. However, students prefer kinesthetic learning styles because the material is delivered practically so that students are more enthusiastic in learning activities.
