Model Discovery Learning Untuk Meningkatkan Kemampuan Pemecahan Masalah

Abstract

Penelitian ini bertujuan untuk meningkatkan kemampuan pemecahan masalah matematis siswa pada materi pokok kubus dan balok dengan model Discovery Learning. Penelitian ini dilakukan di SMP PGRI Kasihan. Teknik pengumpulan data menggunakan observasi dan tes. Teknik analisis data dalam penelitian ini adalah dengan menelaah seluruh data, baik data kualitatif maupun data kuantitatif dari berbagai sumber yaitu hasil observasi, tes tertulis, dokumentasi, dan catatan lapangan. Berdasarkan hasil penelitian dapat disimpulkan bahwa model Discovery Learning dapat meningkatkan kemampuan pemecahan masalah matematis siswa kelas VIII C SMP PGRI Kasihan pada pembelajaran matematika. Hasil penelitian yang diperoleh sebagai berikut: (1) pencapaian kategori tinggi dalam penerapan model Discovery Learning, (2) hasil nilai rata-rata tes tiap siklus mengalami peningkatan, dan (3) skor tiap aspek pemecahan masalah pada mata pelajaran matematika mengalami peningkatan. AbstractThis research aims to improve the ability of the mathematical problem solving of students on the subject matter of the cube and the beams with a model of Discovery Learning. This research was conducted at the SMP PGRI Kasihan. Data collection techniques using observation, test, documentation, and records of the Court. The technique of data analysis in this research is to examine all the data, both qualitative data and quantitative data from a variety of sources that the results of observation and test. Based on the results of the study, it can be concluded that the model of Discovery Learning can improve the ability of mathematical problem solving of students of class VIII C for mathematics learning. The research results obtained as follows: (1) the achievement of the high category in implementation model of Discovery learning; (2) the results of the average value of each test cycle has increased; and (3) score each aspect of problem-solving in mathematics has increased.

Mathematical Problem Solving Ability in Indonesia

“…The research was dominated by 8th grade of junior high school, for example the problem found in the research conducted by Jana and Fahmawati (2020) that students' mathematical problem solving abilities were still very low. Students are still very difficult to work on problems in the form of problems.…”

“…The study was dominated by 8th grade of junior high school because many mathematical problems were found at the 8th grade junior high school level, for example the problems found in the research conducted by Jana and Fahmawati (2020) that students' mathematical problem solving abilities were still very low. Students still have difficulty working on problems in the form of problems (Parlina, Septian, & Inayah, 2021;Septian, Komala, & Komara, 2019).…”

“…Students still have difficulty working on problems in the form of problems (Parlina, Septian, & Inayah, 2021;Septian, Komala, & Komara, 2019). Students also find it difficult what steps to take first to solve the problem (Jana & Fahmawati, 2020). Likewise, research conducted by (Yuli et al, 2020), states that Based on preliminary studies obtained from mathematics teachers in 8th grade of junior high school that there are still many students who have not reached the KKM set by the school, which is 60.…”

Development of Multiplication and Division Concept Learning Media to Increase Student’s Problem Solving Skill and Learning Interest

“…It will make student to think critically, logically, creatively indispensable in dealing with the development of society (Istikomah & Jana, 2019). Problem solving is the ability and knowledge that is central to teaching and learning activities in mathematics (Jana & Fahmawati, 2020;Usman, 2014). According to the Big Indonesian Dictionary, understanding comes from the word understanding, which means the process, method, act of understanding or understanding (Fitriani & Maulana, 2016).…”

Optimalisasi Guided Discovery Learning Untuk Meningkatkan Self-Confidence Siswa Dalam Pembelajaran Matematika

“…Model guided discovery learning mengarahkan siswa ikut aktif berpartisipasi dalam pembelajaran sehingga dapat memperkuat konsep belajar (Mahanani, Rahayu, & Fajaroh, 2019) dan membantu siswa dalam meningkatkan keterampilan pemecahan masalah matematika (Jana, Anisa, & Fahmawati, 2020). Selain itu, penelitian Hasugian (2018) memiliki hasil bahwa model guided discovery learning efektif ditinjau dari prestasi belajar siswa.…”
