THE EFFECT OF GUIDED DISCOVERY LEARNING MODEL TOWARD STUDENT’S MATHEMATICAL REPRESENTATION SKILL

Abstract

This experimental research aimed to analyzed the effect of guided discovery learning model toward student’s mathematical representation skill. The population of this research was the eighth grade student of SMP Muhammadiah 3 Bandarlampung in academic year 2018/2019 as many as 211 students that were distributed into seven classes. Samples of this research were the student of class VIII C consist of 3 students  and VIII E consist of 31 students that were selected through purposive sampling technique. The design of this research was pretest-posttest control grup design. Data analysis in this research used t’-test and proportion test with α = 0,05. Based on the research result, that student’s matematical representation skill who followed the guided discovery learning model was higher than students who followed the non-guided discovery learning model. Thus, the guided discovery learning model affect student's mathematical representation skill.

Keywords: effect, guided discovery learning, mathematical representation skill

Peneli­ti­­an ini bertujuan untuk menganalisis pengaruh model guided discovery learning terhadap kemampuan representasi matematis siswa. Populasi penelitian adalah seluruh siswa kelas VIII SMP Muhammadiah 3 Bandarlampung tahun pelajaran 2018/2019 sebanyak 211 siswa yang terdistribusi dalam tujuh kelas. Sampel penelitian adalah siswa kelas VIII C sebanyak 31 siswa dan VIII E sebanyak 31 siswa yang dipilih dengan teknik purposive sampling. Desain penelitian adalah pretest-posttest control group design. Analisis data yang digunakan adalah uji t dengan taraf signifikan  α = 0,05. Berdasarkan hasil penelitian dan pembahasan, diperoleh informasi bahwa kemampuan representasi matematis siswa yang mengikuti model guided discovery learning lebih tinggi dari siswa yang mengikuti model non-guided discovery learning. Dengan demikian, model guided discovery learning berpengaruh terhadap kemampuan representasi matematis siswa.
