Abstract

Abstract. Mathematics is a lesson that is taught from primary education to higher education. However, the implementation of learning, especially SMP were encountered obstacles, one of which is the lack of representative learning device. This study was a response to the need for a valid learning tool, especially book teacher and student book. This research development, namely the development of learning tools based on open-ended approach to improve the ability to think creatively mathematical school students with materials Statistics. Software development models used in this study was a modification of the steps Plomp model, namely (1) preliminary investigation phase (phase preliminary investigation), (2) design phase (phase design), (3) realization/construction phase (phase realization/construction), and (4) test, evaluation, and revision phase (phase test, evaluation and revision. The device consists of learning learning implementation plan (RPP), teacher guide, student books, student worksheet and the test of learning outcomes. Methode of data collection was done through the validation sheet, test, and questionnaire of students’ responses. Results of the validation sheet was obtained that the RPP had an average value of 4.05 with valid criteria, teacher guide had an average value of 3.94 with valid criteria, students’ books had an average value of 3.9 with valid criteria, student worksheet had an average value of 3.83 with valid criteria, and test results of learning had an average value of 4.15 with very valid criteria. Students' response to the five components was as much as 94.3%.Keywords: Software development learning, model plomp, open-ended approach, mathematical creative thinking ability

Abstract

Kebiasaan pembelajaran yang terlalu didominasi aktivitas guru tanpa keikutsertaan aktif siswa dalam kegiatan pembelajaran matematika menjadi salah satu faktor penyebab kurang menariknya pembelajaran matematika sehingga kemampuan berpikir kreatif dan kritis matematika siswa yang diharapkan tidak meningkat dan kegiatan pembelajaran pun dirasakan kurang bermakna bagi siswa. Oleh karena itu, diperlukan suatu kegiatan pembelajaran yang dapat menuntun siswa berpikir kreatif dan kritis dalam mengkontruksikan ide-idenya melalui berbagai model pembelajaran yang dapat menjawab tantangan tersebut adalah model pembelajaran (PBL) Problem Based Learning. Berdasarkan hal tersebut dapat dilakukan penelitian tentang pembelajaran materi perbandingan dengan menyelesaikan pembelajaran matematika melalui model pembelajaran PBL pada siswa kleas VII SMP Muhammadiyah 6 Lhokseumawe. Penelitian ini menggunakan pendekatan kualitatif dengan jenis penelitian tindakan kelas (PTK). Subjek penelitian ini adalah siswa kelas VII sebanyak 22 orang. Adapun indikator keberhasilan penelitian ini adalah sebagai berikut : penelitian ini berhasil apabila ≥80% siswa memperoleh nilai KKM ≥75 dan kegiatn pembelajaran guru dan siswa berdasarkan hasil observasi berada pada kategori “baik”. Secara keseluruhan hasil penelitian dengan menerapkan model pembelajaran PBL menunjukkan bahwa hasil belajar matematika siswa mengalami perubahan yaitu dari hasil akhir siklus II siswa yang mencapai KKM yaitu 90%, hasil ini lebih besar dari persentase yang diperoleh pada hasil akhir siklus I yaitu sebesar 59%, dan persentase siklus ke II tersebut lebih besar dari standart ketuntasan yang ditetapkan. Begitu pula dengan hasil observasi siklus II terhadap kegiatan peneliti mencapai 85%, hasil ini lebih besar dari persentase yang diperoleh peneliti pada siklus I yaitu sebesar 75%. Karena persentase yang diperoleh lebih besar dari pada standar yang ditetapkan maka diputuskan bahwa siklus II telah berhasil dan tidak perlu dilanjutkan ke siklus berikutnya. Sehingga, dengan menerapkan model pembelajaran Problem Based Learning ada peningkatan hasil belajar matematika siswa kelas VII SMP Muhammadiyah 6 Lhokseumawe.

Abstract

The purpose of this study was to describe mathematical problem solving abilities in solving Higher Order Thinking Skill (HOTS) questions on the subject of opportunities for permutations and combinations of MAN Lhokseumawe students. In general, students' mathematical problem-solving skills are still lacking in solving HOTS-shaped problems, both at the steps of understanding the problem, planning a solution, solving problems, and re-examining. This type of research uses a descriptive qualitative approach by providing problem-solving ability test questions in the form of HOTS and selecting interview subjects according to predetermined abilities. The results of the research on the percentage of students' answers to the steps of problem-solving skills are: understanding the problem 37%, planning a solution 51%, solving the problem 68%, and checking back 21%. So it can be concluded that students' mathematical problem solving abilities in solving HOTS questions on the subject of permutations and combinations of probabilities are still low in understanding the problem, good enough in re-planning, good enough in solving problems, and quite low in re-examining.
