Abstract

The purpose of this study is to improve students’ creativity through problem solving learning. Students’ creativity is an important issue in Mathematics Economics class. Some of the problems that occur are (1) the lack of students in asking questions; (2) low idea of students; (3) lack of courage in expressing opinions; (4) lack of ability to solve difficult mathematical problems in class, and (5) ) lack of courage in defending his opinion when discussing. This research is a classroom action research on mathematics economics course in Mathematics Education Department, University of Muhammadiyah Purwokerto in 2018/2019 academic year. The research phase includes (1) planning, (2) implementing actions, (3) observation, and (4) reflection. The results of this study show good results, because of the 55 students, only 3 students who scored less in the category and the second cycle only 1 student who scored less. Therefore, it can be concluded that problem solving learning can enhance students’ creativity.

Abstract

Penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematis mahasiswa semester 1 Program Studi Pendidikan Matematika Universitas Muhammadiyah Purwokerto melalui pembelajaran GAB (Geometri Analitik Bidang) yang termodifikasi dengan teori Dienes dan Van Hiele. Kemampuan representasi matematis merupakan kemampuan untuk mengungkapkan gagasan atau ide-ide matematika dalam upaya untuk mencari suatu solusi dari masalah yang sedang dihadapi. Oleh karena itu, dengan merepresentasikan idenya mahasiswa akan mengalami kemudahan dalam menyelesaikan suatu permasalahan matematika. Model pembelajaran yang digunakan adalah model pembelajaran yang termodifikasi dengan teori belajar Dienes dan teori belajar Van Hiele. Subjek penelitian adalah mahasiswa semester 1 kelas A yang berjumlah 35 mahasiswa Program Studi Pendidikan Matematika Universitas Muhammadiyah Purwokerto, sedangkan objek penelitian adalah seluruh proses dan hasil pembelajaran matematika dengan penerapan pembelajaran yang termodifikasi Dienes dan Van Hiele untuk mengetahui deskripsi kemampuan representasi matematis mahasiswa di kelas tersebut. Instrumen penelitian berupa lembar observasi kemampuan representasi matematis, pedoman wawancara, dan tes kemampuan representasi matematis. Hasil penelitian menunjukkan pembelajaran pada mata kuliah Geometri Analitik Bidang yang telah dimodifikasi dengan teori belajar Dienes dan Van Hiele dapat membantu perkembangan kemampuan representasi matematis mahasiswa. Pengembangan pembelajaran dilakukan sesuai dengan kebutuhan pada mahasiswa.

Abstract

This study was employed to enhance learning motivation and mathematical problem-solving abilities of class VIII A students of SMP Negeri 7 Purwokerto through SFAE learning with problem-solving strategies. The subjects of this study were 31 students of class VIII A SMP Negeri 7 Purwokerto. This study is a Classroom Action Research (CAR), which was conducted collaboratively and participative. The action research was carried out in 3 cycles, with each cycle consisting of 2 meetings. Students were given a questionnaire to measure learning motivation and a test to measure their mathematical problem-solving abilities at the end of each cycle. Data collection techniques in this study include observation, questionnaires, tests, and documentation. Data analysis was carried out by descriptive qualitative and quantitative. The finding showed that implementing of SFAE learning with problem-solving strategies could increase students’ learning motivation and mathematical problem-solving abilities. The study found that (1) The average percentage of the overall learning motivation questionnaire is steadily increased from 61.71% in cycle one to 68.10% in cycle two and 76.03% in cycle three. (2) The average percentage of student tests for problem-solving abilities in cycle one also significantly increases from 35.21% to 53.20% in cycle two and 79.61% in cycle three. The average student test rate for each indicator of problem-solving ability has met the study’s success criteria.
