Abstract

Learning that does not involve active student participation can influence student activities, especially in mathematics learning using NHT type cooperative learning models. This study aims to determine an increase in the activity of learning mathematics in class VII D students in the even semester of SMP Muhammadiyah 2 Mlati in the 2015/2016 academic year by using the NHT type of cooperative learning model. This research is a Classroom Action Research (CAR). The setting used is class VII D, amounting to 30 students. The research plan is carried out in 3 Cycles and complete in Cycle III. In Cycle I consisted of 1 meeting, Cycle II consisted of 2 meetings, and Cycle III consisted of 1 meeting. Each Cycle uses NHT type cooperative learning models. Data collected by observation, interview and documentation. Analysis of the data used is qualitative descriptive analysis. The results showed that mathematics learning using the NHT type of cooperative learning model could increase the learning activity of students of class VII D even semester of SMP Muhammadiyah 2 Mlati, Sleman Regency Academic Year 2015/2016. This is evident from the increase in student learning activities. In Cycle I, Cycle II and Cycle III that use the NHT type of cooperative learning model experienced an increase in which the first cycle the average percentage of student activity was 37.92% with poor criteria, the average percentage of activeness in cycle II was 52.5% with sufficient criteria and the average percentage of activeness in cycle III is 65.28% with good criteria.

Abstract

Tujuan dari penelitian ini adalah untuk mengetahui pengaruh pembelajaran guided discovery dalam meningkatkan pemahaman siswa tunanetra. Penelitian ini merupakan penelitian eksperimental dengan desain Single Subject Research (SSR) A-B. Siswa yang digunakan sebagai subjek dalam penelitian ini adalah siswa kelas VII MTs Yaketunis Yogyakarta. Pengumpulan data melalui tes, observasi dan wawancara. Analisis data dilakukan berdasarkan hasil pada fase baseline maupun intervensi yang berada pada dua kondisi, yaitu dalam kondisi dan antar kondisi. Hal ini terlihat dari peningkatan hasil tes pemahaman siswa pada fase baseline dengan skor 43, 41 dan 50 menjadi 80, 83, 81, dan 90 pada fase intervensi. Demikian halnya dengan hasil analisis dalam kondisi yang menunjukkan bahwa fase intervensi memiliki arah kecenderungan arah dan stabilitas yang signifikan lebih meningkat daripada fase baseline. Melalui observasi dan wawancara juga diketahui konsistensi jawaban yang menunjukkan pemahaman konsep sudut siswa sudah terkonstruksi. Dengan pembelajaran guided discovery, siswa tidak hanya sekedar menghafal konsep tapi lebih pada aktivitas belajar bermakna dengan mengonstruksi dan memahami konsep secara mandiri, sehingga hasil belajarnya bertahan lama dalam memori siswa.
