Efektivitas Model Pembelajaran Discovery Ditinjau dari Kemampuan Komunikasi Matematis Siswa

Abstract

Abstract: The Effectiveness of Discovery Learning Model in Terms of Students Mathematical Communication Skills. This quasi experimental research aimed to examine the effectiveness of discovery learning model in terms of students mathematical communication skills. The population of this research was all students of grade VII of SMP Negeri 26 Bandarlampung in even semester in academic year 2018 2019 as many as 233 students, that were distributed into eight classes. By using purposive sampling technique, two classes were taken as the sample that were VII B class as many as 30 students and VII D class as many as 29 students. This research used the pretest posttest control group design and the data collecting technique was test. The data obtained from this research was the score of students mathematical communication skills. Based on the result of t test and proportion test using 5 percent of significance level, it was concluded that discovery learning model was not effective in terms of students mathematical communication skills. However, the mathematical communication skills of students who following discovery learning was higher than mathematical communication skills of students who following conventional learning.

Abstrak: Efektivitas Model Pembelajaran Discovery Ditinjau dari Kemampuan Komunikasi Matematis Siswa. Penelitian eksperimen semu ini bertujuan untuk mengetahui efektivitas model pembelajaran discovery ditinjau dari kemampuan komunikasi matematis siswa. Populasi penelitian yaitu seluruh siswa kelas VII SMP Negeri 26 Bandarlampung semester genap tahun pelajaran 2018 2019 sebanyak 233 siswa yang terdistribusi dalam delapan kelas. Sampel penelitian ini adalah seluruh siswa kelas VII B sebanyak 30 siswa dan VII D sebanyak 29 siswa yang dipilih melalui teknik purposive sampling. Desain yang digunakan adalah pretest posttest control group design dengan teknik penilaian menggunakan teknik tes. Data yang diperoleh berupa data nilai tes kemampuan komunikasi matematis siswa. Berdasarkan uji t dan uji proporsi dengan taraf signifikansi 5 persen, diperoleh kesimpulan bahwa model pembelajaran discovery tidak efektif ditinjau dari kemampuan komunikasi matematis siswa. Namun, siswa yang mengikuti pembelajaran discovery memiliki kemampuan komunikasi matematis yang lebih tinggi dibandingkan dengan siswa yang mengikuti pembelajaran konvensional.
