Pengaruh LKPD Untuk Memfasilitasi Kooperatif Group Investigation Dalam Meningkatkan Keterampilan Proses Sains Siswa SMP Dan MTs

The Effect of LKPD to Facilitate Cooperative Group Investigation in Improving Science Process Skills for Junior High School and Madrasah Tsanawiyah Students

Penelitian ini bertujuan untuk mengidentifikasi pengaruh LKPD untuk memfasilitasi kooperatif group investigation dalam meningkatkan keterampilan proses sains siswa pada pembelajaran IPA materi gerak benda siswa kelas VIII di MTs Ulul Albab, SMP Ulul Albab, dan MTs Akhyariyah tahun ajaran 2020/2021. Penelitian ini merupakan jenis penelitian Quasi Experimental dengan desain penelitian Nonequivalent Control Group design. Sampel yang digunakan adalah seluruh siswa kelas VIII SMP dan MTs. Teknik analisis pengujian hipotesis keterampilan proses sains siswa menggunakan Uji-t sampel bebas, N-gain score, dan uji anova. Model group investigation berbasis LKPD cukup efektif dalam meningkatkan keterampilan proses sains siswa kelas VIII SMP dan MTs. Sementara pembelajaran group investigation tanpa LKPD kurang efektif dalam meningkatkan keterampilan proses sains kelas VIII SMP dan MTs sesuai hasil N-gain. Peningkatan keterampilan proses sains siswa di tiga sekolah adalah sama, sesuai nilai F_hitung < F_tabel (0,604 < 3,37). Rata-rata angket respon siswa MTs Ulul Albab, SMP Ulul Albab, dan MTs Akhyariyah sebesar 83,29% dengan kategori baik. Berdasarkan hasil analisis data tersebut maka dapat disimpulkan bahwa terdapat pengaruh LKPD untuk memfasiitasi group investigation dalam meningkatkan keterampilan proses sains siswa SMP dan MTs.

This study purpose to identify the effect of worksheet to facilitate cooperative group investigation in improving students' science process skills in learning science of object motion material for class VIII students at MTs Ulul Albab, SMP Ulul Albab, and MTs Akhyariyah for the academic year 2020/2021. This research is a quasi-experimental research with a Nonequivalent Control Group design. The samples used were all students of class VIII SMP and MTs. The analysis technique for testing the hypothesis of students' science process skills was using the free sample t-test, N-gain score, and the ANOVA test. The worksheet -based group investigation model is quite effective in improving the science process skills of class VIII SMP and MTs students. Meanwhile, group investigation learning without LKPD is less effective in improving science process skills for class VIII SMP and MTs according to the results of N-gain. The improvement of students' science process skills in the three schools was the same, according to the value of Fcount < Ftable (0.604 < 3.37). The average questionnaire response of students at MTs Ulul Albab, SMP Ulul Albab, and MTs Akhyariyah was 83.29% in the good category. Based on the results of the data analysis, it can be concluded that there is an influence of worksheet to facilitate group investigation in improving the science process skills of Junior high school and Madrasah Tsanawiyah students.
