Abstract

This research goals to fix the activeness and knowing results of students using the STAD type cooperative learning model on the subject matter of algebraic function limits. The points of this research were students of grade XII RPL 2 SMK AL-Ihsan Batujajar with a total of 26 students, consisting of 9 male students and 17 female students. The instrument used in this study was the observation sheet and the test description and interview of the mathematics teacher at the school. The results of student activeness research in the first cycle of 65.38% were in the criteria of being quite active, and the second cycle at 84.61% were in active criteria. And the results of research on student learning outcomes in the first cycle is in the percentage of class completeness by 53.84% and in the second cycle is the percentage of class completeness by 92.30%, it can be seen student learning outcomes from cycle I has intensified in cycle II. Based on the research outcomes, it can be resumed that the use of the STAD type of cooperative upgrading on the subject of algebraic functional limit in class XII RPL 2 SMK AL-Ihsan Batujajar there is an influence of increasing student learning outcomes and activeness.

Abstract

Penelitian ini dilatarbelakangi oleh pembelajaran yang kurang terhubung dengan kehidupan nyata, sehingga siswa kurang paham dengan pembelajaran. Penyebabnya adalah karena cara mengajar guru yang masih terlalu berpatokan pada buku pelajaran. Solusinya, peneliti menerapkan model pembelajaran pendekatan kontekstual. Pendekatan Kontekstual merupakan pendekatan dengan konsep belajar yang mengaitkan materi dengan kehidupan nyata. Jenis penelitian ini adalah penelitian kualitatif. Tujuan penelitian adalah untuk mengetahui penerapan pendekatan kontesktual terhadap siswa kelas VIII SMP terhadap materi perbandingan dan skala. Sampel penelitian yaitu siswa kelas VIII A SMP Pasundan Rongga 2019/2020. Instrumen penelitian adalah soal tes berbentuk uraian dan pedoman wawancara. Penelitian mengacu pada, siswa dapat menyelesaikan soal cerita dengan langkah-langkahnya, siswa mengerjakan sesuai intruksi.Hasil analisis data wawancara, bahwa penerapan pendekatan kontekstual terhadap siswa kelas VIII SMP Pasundan Rongga masih mengalami kesulitan dalam menyelesaikan soal cerita. This research is motivated by learning that is less connected to real life, so students lack an understanding of learning. The reason is because of the way to teach teachers who still rely too much on textbooks. The solution, researchers apply a learning model of contextual approaches. A contextual Approach is an approach to the concept of learning that links material with real life. This type of research is qualitative research. The purpose of this study was to determine the application of the contextual approach to eighth-grade students of SMP on comparison and scale material. The research sample is students of class VIII A, Pasundan Cavity 2019/2020. The instrument in this study was a test item in the form of a description and interview guidelines. Research refers to, students can solve story problems with steps, students work according to instructions. The results of the interview data analysis show that the application of the contextual approach to the eighth-grade students of Pasundan Rongga Middle School still had difficulty in completing story questions.

Abstract

Mempelajari matematika dianggap sulit oleh mayoritas siswa. Solusinya, peneliti menerapkan sebuah pendekatan pembelajaran kontekstual. Penelitian ini bertujuan untuk menyelidiki faktor-faktor penyebab kesulitan siswa dalam mempelajari materi perbandingan. Penelitian deskriptif kualitatif ini menggunakan instrumen soal cerita berjumlah 3 soal. Subjek penelitian adalah 24 orang siswa yang dipilih secara purposive sampling pada salah satu SMP di Kabupaten Bandung Barat. Pengumpulan data dilakukan dengan menggunakan tes dan wawancara. Hasil penelitian kemudian dianalisis secara deskriptif untuk mencapai tujuan penelitian. Hasil penelitian menunjukkan bahwa siswa SMP Pasundan Rongga belum sepenuhnya mencapai target yang diharapkan. Siswa masih banyak yang mengalami kesulitan untuk menyelesaikan soal cerita. Kesulitan siswa yang dominan dapat dikategorikan ke dalam tiga bentuk, yaitu kurangnya pemahaman konsep, tergesa-gesa menyelesaikan soal, dan kurangnya memahami soal. Berdasarkan hasil wawancara, penyebab kesulitan tersebut karena siswa belum terbiasa diberikan soal berbentuk cerita. Soal cerita perlu lebih sering diberikan kepada siswa guna menambah pengalaman belajarnya. Learning mathematics is considered difficult by the majority of students. The solution, researchers apply a contextual learning approach. This study aims to investigate the factors that cause students' difficulties in studying comparative material. This qualitative descriptive study used three-story questions as instruments. The research subjects were 24 students who were selected by purposive sampling at one of the junior high schools in West Bandung Regency. Data collection was carried out using tests and interviews. The research results were then analyzed descriptively to achieve the research objectives. The results showed that the students of SMP Pasundan Rongga had not fully achieved the expected targets. There are still many students who have difficulty solving story questions. The students' dominant difficulties can be categorized into three forms, namely a lack of understanding of the concept, rushing to solve the problem, and a lack of understanding the problem. Based on the results of the interview, the cause of the difficulty was because students were not used to being given questions in the form of stories. Story questions need to be given to students more often in order to increase their learning experience.
