Pengaruh Pembelajaran Inkuiri Terbimbing Terhadap Kemampuan Berpikir Reflektif Matematis dan Self Confidence

Abstract

This study aims to determine the influence of guided inquiry learning model towards mathematical reflective thinking skills and self confidence. The research population were all students of VII grade Bandarlampung State Middle School 8 semester 2018/2019 academic year as many as 280 students and distributed into nine classes. The research sample were all students of class VII A and VII B who were selected through cluster random sampling technique. The design used were the randomized pretest-posttest control group design and the randomized posttest only control group design. The research data analysis showed that the increase in students’ mathematical reflective thinking skills in guided inquiry learning was higher than conventional learning, but there was no difference in the average students' self confidence in guided inquiry learning and conventional learning. Based on the results of the research and discussion, it was concluded that the guided inquiry learning model influenced students' mathematical reflective thinking skills, but did not influence students' self confidence.

Penelitian ini bertu­juan untuk mengetahui pengaruh pembelajaran inkuiri terbimbing terhadap kemam­puan berpikir reflektif matematis dan self confidence. Populasi penelitian adalah seluruh siswa kelas VII SMP Negeri 8 Bandarlampung semester ganjil tahun pelajaran 2018/2019 sebanyak 280 siswa dan terdistribusi ke dalam sembilan kelas. Sampel penelitian adalah seluruh siswa kelas VII A dan VII B yang dipilih melalui teknik cluster random sampling. Desain yang digunakan adalah the randomized pretest-posttest control group design dan the randomized posttest only control group design. Analisis data penelitian menunjukkan bahwa peningkatan kemampuan berpikir reflektif matematis siswa pada pembelajaran inkuiri terbimbing lebih tinggi daripada pembelajaran konvensional, namun tidak ada perbedaan rata-rata self confidence siswa pada pembelajaran inkuiri terbim­bing dan pembelajaran konvensional. Berdasarkan hasil penelitian dan pembaha­san, disimpulkan bahwa  model pembelajaran inkuiri terbimbing berpengaruh ter­hadap kemampuan berpikir reflektif matematis siswa, namun tidak berpengaruh terhadap self confidence siswa.
