Abstract

Penelitian ini bertujuan untuk mengetahui keefektifan pendekatan problem based learning (PBL) dan  problem solving (PS) ditinjau dari kemampuan berpikir kritis dan kemandirian belajar siswa. Penelitian ini merupakan penelitian eksperimen semu dengan desain penelitian Nonequivalent Pretest-Posttest Group Design. Populasi dalam penelitian ini siswa SMP di Gantiwarno dan sampel penelitian kelas VIIIC dan VIIID. Instrumen pengumpulan data menggunakan tes kemampuan berpikir kritis, angket kemandirian belajar siswa, dan lembar observasi keterlaksanaan pembelajaran. Validitas isi dilakukan dengan v aiken diperoleh nilai v hitung pretest sebesar 0,97 dan v hitung posttest sebesar 0,99 lebih besar dari v tabel. Estimasi reliabilitas dengan alpha croncbach diperoleh hasil estimasi nilai reliabitas pretest sebesar 0,861, posttest sebesar 0,832, dan angket sebesar 0,90. Hasil reliabilitas alpha croncbach ini > 0,70 maka reliabilitas terpenuhi. Hasil penelitian dan analisis data diperoleh bahwa pendekatan PBL lebih efektif dibandingkan pendekatan PS dalam meningkatkan kemampuan berpikir kritis dan kemandirian belajar siswa SMP.

Abstract

The Covid-19 pandemic has hampered learning while at the same time making teachers and students learn to carry out online learning. There are obstacles in the implementation of online learning such as the difficulty for teachers to engage active students and decreased student achievement. To overcome this, there is a need for learning innovation by implementing blended learning. The blended learning program is a learning model that combines face-to-face learning with online learning. The purpose of this study was to evaluate the blended learning program at SD N 1 Baturan and to find out the supporting and inhibiting factors in implementing blended learning. The method used in this research is a case study with a qualitative approach. Data collection techniques are carried out by observation, interviews, and documentation. The results of the evaluation show that the blended learning program at SD N 1 Baturan has been implemented well even though it has several obstacles and there are several supporting and inhibiting factors for the blended learning program. Supporting factors include the school environment, government, and teaching staff, while inhibiting factors include facilities and infrastructure, students' technological literacy, and face-to-face time limitations.

Abstract

Education plays an important role in creating a young generation to be able to compete in the era of globalization, one of which is through mathematics learning. The objectives of mathematics learning include mathematical communication, learning to reason mathematically, learning to solve problems, and learning to connect ideas. These abilities are abilities that students must have in facing global challenges. This study aims to determine the improvement of communication skills, the sharpness of mathematical problem solving, and self-efficacy using a scientific approach through the application of the discovery learning model. This study is a quantitative study, and the type of research used in this study is quasi-experimental. The research design used is one group pretest-posttest. This study was conducted in one of the high schools in West Aceh. The study population was 29 grade 10 students. Data collection techniques used test and non-test methods. The findings of the study showed a significant increase in communication skills, problem-solving abilities, and self-efficacy when using the discovery learning approach in the context of trigonometric ratios. The approach is considered quite effective, which means it produces a substantial increase in the cognitive abilities mentioned above among students.
