Abstract

Siswa menganggap matematika sebagai pelajaran yang sulit sehingga membuat mereka kurang memahami konsep dalam pelajaran matematika. Kemampuan siswa untuk memahami konsep abstrak matematika juga sangat tergantung pada model, rencana pelajaran, atau alat belajar yang digunakan. Untuk itu penelitian ini bertujuan untuk mengembangkan modul matematika dengan Realistic Mathematics Education (RME) dengan bermuatan soal High Order Thinking Skill (HOTS). Materi pada modul ini yaitu sistem persamaaan linear dua variabel. Penelitian pengembangan ini menggunakan empat fase dari model Plomp, yaitu: 1) pengumpulan informasi awal; 2) desain; 3) konstruksi; dan 4) tes, evaluasi, dan revisi. Subjek pada penelitian ini adalah siswa kelas IX. Instrumen yang digunakan dalam penelitian adalah lembar validasi ahli, yang terdiri atas ahli pendidikan, materi dan media, serta angket kepraktisan untuk guru dan respon siswa. Para ahli menilai modul dengan memberikan skor 1-5 terhadap modul. Berdasarkan hasil uji ahli didapat rata-rata skor sebagai berikut: 4,5 untuk ahli media, yang mencakup kriteria yang sangat valid; 4.65 untuk ahli materi, yang mencakup kriteria yang sangat valid; dan 4.56 untuk ahli pendidikan, yang mencakup kriteria sangat valid. Hasil angket praktikalitas guru dan respon siswa masing-masing sebesar 94.54% dan 91.56% dengan kriteria keduanya adalah sangat baik. Berdasarkan hal tersebut maka modul matematika berbasis RME dengan soal HOTS layak digunakan khususnya untuk siswa kelas IX. Kata Kunci: Modul Matematika; RME; HOTS

Abstract

E-learning, assisted by Google Classroom, can be used to provide material and discussions. This research aimed to analyze the effect of e-learning on mathematical disposition and mathematical concept understanding using discovery learning. This research was experimental research with a non-equivalent control group design. The population of this research was the eleventh-grade science students (168 students). The sampling technique employed was random cluster sampling. Data collection techniques used were interviews, tests, and questionnaires. The test results showed that students in the experimental class obtained an average score of 71.7, while the control class obtained a score of 62.9. The results of the mathematical disposition questionnaire showed that experimental class students were more active and confident in solving problems. Thus, e-learning using discovery learning can improve mathematical disposition and mathematical concept understanding. It is suggested to the teacher to develop this learning for other materials.

Abstract

Efforts to improve the quality of education continue to be carried out comprehensively, including aspects of knowledge, skills, attitudes, and values. Mathematics learning is understanding mathematical concepts when solving a problem. Therefore, whether or not mathematics learning has been achieved can be demonstrated if students can understand and master a given concept. This research aims to determine the increase in students' ability to understand concepts using teaching materials with a problem-based learning approach. This research used one class with 36 students. Data collection uses observation and tests. The pretest and posttest results show that the posttest results are better, namely having 10.417 points more than the pretest results. The results of the t-test analysis show a significance of 0.000. After being tested, it can be concluded that teaching materials using a problem-based learning approach are effective in improving students' ability to understand mathematical concepts.
