Abstract

The purpose og this study was to describe the critical thinking skills of students with high, medium, and low math abilities in solving math problems. This research is a qualitative descriptive study. The subjects of this study were 3 students of class XI MIPA at SMA Negeri Ngoro Jombang, with categories of high, medium, and low mathematical abilities. Methods of data collection in this study using the method of tests and interviews with the main instruments of the researchers themselves and supporting instruments in the form of test sheets for the ability to think critically in mathematics and interview guidelines. Checking the validity of the research data was done by triangulating time. Data analysis techniques are carried out by reducing, presenting data, and make conclusions The results of this study reveal that the indicator of the ability to think critically in mathematics in solving math problems was that students present the information that was known and what requested from the questions correctly, presents information that had not been clearly stated in the questions and the information needed to solve the problems, presents conclusions of concepts / ideas that are relevant to solving the problem, and presenting the steps for completion in a coherent and correct manner and presenting the correct result of solving the problem. The ability to think critically in mathematics of students who have high abilities in solving questions is able to meet all indicators of critical thinking skills, students who are able to think critically in mathematics who are moderate in solving questions are able to meet the three indicators of critical thinking abilities because students are unable to present the correct results, while the ability critical thinking mathematics students with low ability to solve problems are only able to meet two indicators of critical thinking skills, namely students are only able to present the information that is known and the things that are requested from the questions correctly, presenting information that has not been clearly stated in the questions and the information needed to solve the problem.

Abstract

Penelitian ini dimulai dari observasi awal peneliti terhadap aktivitas dan hasil belajar matematika siswa kelas V SD Negeri Jombatan IV. Peneliti menemukan beberapa masalah dalam pengamatan tersebut diantaranya beberapa siswa masih mengalami kesulitan pada materi menghitung volume kubus dan balok dan siswa tidak dapat menyelesaikan soal apabila diberikan soal yang sedikit berbeda dari yang dipelajari. Peneliti mencoba melakukan pembelajaran dengan penerapan strategi pembelajaran Beach Ball (Bola Pantai) untuk mengatasi hal tersebut. Penelitian ini bertujuan untuk mendeskripsikan penerapan strategi pembelajaran Beach Ball (Bola Pantai) dalam meningkatkan aktivitas dan hasil belajar matematika materi volume kubus dan balok tahun pelajaran 2019/2020. Jenis penelitian ini adalah penelitian tindakan kelas. Rancangan penelitian tindakan kelas yang digunakan dalam penelitian ini adalah model yang dikembangkan oleh Kemmis dan Mc Taggart. Penelitian dilaksanakan dalam 2 siklus, siklus pertama terdiri dari 2 pertemuan dan siklus kedua terdiri dari 2 pertemuan. Peneliti melakukan pengumpulan data dengan cara observasi, dan tes. Subjek dalam penelitian ini adalah siswa kelas V SD Negeri Jombatan IV tahun pelajaran 2019/2020. Hasil penelitian menunjukkan bahwa penerapan strategi pembelajaran Beach Ball (Bola Pantai) dalam pembelajaran matematika materi volume kubus dan balok pada siswa kelas V SD Negeri Jombatan IV dapat meningkatkan aktivitas siswa, dan hasil belajar siswa. Aktivitas siswa pada siklus 1 mencapai 60,62% dengan kriteria cukup menjadi 81,4% pada siklus 2 dengan kriteria baik. Hasil belajar siswa pada siklus 1 mencapai ketuntasan klasikal sebesar 62,85% menjadi 82,85% pada siklus 2
