PENINGKATAN KETERAMPILAN GENERIK SAINS SISWA MELALUI TASK BASED LEARNING PADA LARUTAN BUFFER

Abstract

ABSTRAK Task based learning (TBL) adalah suatu pembelajaran yang menuntut siswa berperan aktif dalam kegiatan pembelajaran sehingga diharapkan dapat meningkatkan keterampilan berpikir dalam memahami konsep-konsep yang dipelajari. Keterampilan generik sains memiliki indikator, di antaranya: pengamatan langsung, pengamatan tidak langsung, bahasa simbolik, inferensi logika, pemodelan matematik, dan membangun konsep. Tujuan penelitian ini untuk mendeskripsikan keterampilan generik sains siswa pada pembelajaran TBL larutan buffer. Metode penelitian yang digunakan adalah metode peneitian tindakan kelas dengan dua siklus sesuai ketercapaian KKM. Subjek penelitian adalah siswa kelas XI IPA-5 dari salah satu SMA negeri di kota Bandung sebanyak 32 orang. Instrumen yang digunakan adalah soal yang mengacu pada indikator keterampilan generik sains. Data hasil penelitian diolah dengan menggunakan statistika dekriptif persentase. Hasil tes keterampilan generik sains siswa mengalami peningkatan dengan rata-rata pada siklus I 70 dan siklus ke II 82. Maka hasil peneltian ini menunjukkan bahwa penerapan TBL dalam pembelajaran kimia dapat meningkatkan keterampilan generik sains siswa. Kata Kunci: Task Based Learning (TBL),Keterampilan generik sains, buffer. ABSTRACT Task Based Learning (TBL) is a kind of learning that requires students to actively participate in learning activities that are expected to improve thinking skills in understanding the concepts being studied. Generic science skill has several indicators, i.e. direct observation, indirect observation, symbolic language, logic inference, mathematical modeling, and building concepts. The purpose of this study was to describe generic science skills of students in learning the concepts of buffer solution through TBL. The method used was classroom action research (two cycles) according to the achievement of KKM. The subject of this study was 32 students belong to class XI IPA-5 in a state high school located in Bandung city. The instrument used in this study was questions/problems refers to indicators of generic science skills. The resulting data was processed using descriptive statistical percentages. The generic science skills test results of students has increased with an average of 70 in the first cycle and 82 in the second cycle. Thus, the results of this research indicate that the application of TBL in chemistry learning could increase the generic science skills of students.
