Abstract

Pembelajaran matematika di setiap tingkat pendidikan lebih berorientasi pada peningkatan kecerdasan siswa dibanding perkembangan kreativitas siswa. Bagi siswa terkadang hasil belajar lebih penting dibandingkan proses saat mereka belajar. Sehingga, siswa lebih mementingkan nilai daripada ilmu yang mereka dapatkan. Dalam pembelajaran matematika di MTs Negeri Sukasari Cimahi, mengenai materi SPLDV, siswa kelas VIII G merasa kesulitan dalam: 1) memahami informasi pada soal cerita SPLDV, dan 2) mengingat dan mengaplikasikan metode-metode penyelesain pada soal SPLDV. Pendekatan open-ended digunakan sebagai salah satu strategi pembelajaran agar terjadi peningkatan pada kemampuan berpikir kreatif matematis siswa. Penelitian ini dilakukan dengan 2 siklus dengan setiap siklus terdiri dari 2 pertemuan. Sebelum dimulai tindakan dilakukan tes awal kepada siswa, kemudian dilanjutkan dengan kegiatan siklus I dan siklus II yang menggunakan pendekatan open-ended. Hasil penelitian ini menunjukkan adanya peningkatan kemampuan berpikir kreatif matematis siswa terlihat dari ketuntasan hasil belajar siswa yaitu pada hasil tes awal tidak ada siswa yang nilainya melebihi KKM, pada siklus I terjadi peningkatan sebesar 30,6%, pada siklus II terjadi peningkatan sebesar 47,2%. Hal ini menunjukkan bahwa kemampuan berpikir kreatif matematis siswa kelas VIII MTs Negeri Sukasari Cimahi dapat ditingkatkan melalui pendekatan open-ended.

Abstract

This research is a descriptive study that aims to find out the difficulties faced by students in solving the problem of understanding mathematical concepts. Indicators of the ability to understand concepts as learning outcomes of mathematics are as follows: (1) The ability to restate a concept; (2) The ability to clarify objects according to certain characteristics in accordance with the concept; (3) Ability to give examples and not examples; (4) Ability to present concepts in various forms of mathematical representation; (5) Ability to develop necessary requirements or sufficient requirements from a concept; (6) Ability to use, utilize and choose certain procedures; (7) Ability to clarify concepts or algorithms to problem solving. The subject of this study was 80 students of class VIII SMP PGRI 1 Cimahi 2017/2018 school year. The instruments in this study included the ability test sheet to understand concepts and interview guidelines. Based on the results of data analysis and discussion, it can be concluded that students cannot arrange the meaning of words that are thought in the form of mathematical sentences, less careful, forgetfulness, less practice in working on the problems of storytelling with varying ones and lack of understanding the questions.

Abstract

This research is aims to improve learning approach Discovery learning and Self Confidence to junior high school students on two linears equation. The research was conducted in one of Junior High School in Purwakarta. understanding of students in understanding the concept of system of linear equations of two variables is still very low because students emphasized the use of  formulas and routine exercises. because of that, the researcher seeks to apply learning approach Discovery Learning to stundents Self Confidence. this research uses classroom action research method which is implemented through two cycles consisting of one cycle on one meeting. the instrument used is the observation sheet, interview, preliminary tests and tests each cycle. In the preliminary tests showed that confidence in the mastery of the concept of linear equations of learners is still very low. On the cycle of a stundent's activities is listening explanation about the matter of concept of linear equation of two variable, identifiying, collecting information, and solving the problems that the teacher provides. On the one cycle many students are still confused in understanding the two-variable linear equation material and their confidence are still very low. In the second cycle the students has improved in understanding the concept of linear equations of two variables and has a good selfconfidence. The result of this research showed that the used of learning approach Discovery Learning on stundent's self confidence  on understanding the concept of linear equations of two variables has increased.
