DEVELOPMENT OF STUDENTS WORKSHEET BASED ON METACOGNITIVE STRATEGY ON STOICHIOMETRY MATTER FOR X GRADE SENIOR HIGH SCHOOL STUDENTS

Abstract

Tujuan penelitian ini adalah untuk mengembangkan LKS berbasis strategi belajar metakognitif pada kategori metacomprehension pada materi perhitungan kimia dan mendeskripsikan kelayakan LKS, serta untuk mengetahui respon siswa terhadap LKS yang dikembangkan. Metode penelitian yang digunakan adalah model 4-D tetapi hanya tiga tahap yang dilakukan pada pengembangan ini (3-D models), yaitu define, design, develop. Sasaran penelitian ini yaitu lembar kerja siswa berbasis strategi belajar metakognitif terutama kategori metacomprehension pada materi perhitungan kimia. Uji coba LKS secara terbatas di SMA Negeri 2 Lamongan pada 20 siswa kelas XI. Hasil penelitian menunjukkan bahwa kelayakan LKS mendapat rata-rata skor validasi untuk tiap aspek, meliputi aspek komponen LKS, penyajian LKS, isi LKS, kesesuaian dengan komponen bahasa dan kesesuaian dengan kriteria metacomprehension dengan skor berturut-turut sebesar 83,33%, 80%, 86,67%, 85%, 80%, dan 97% dengan kategori kuat. Dan siswa merespon positif terhadap LKS yang dikembangkan dengan skor ≥ 61% untuk tiap aspek, dengan skor tiap aspek berturut-turut sebesar 97%, 92%, 100%, dan 97%..

Kata kunci: lembar kerja siswa berbasis strategi belajar metakognitif, metacomprehension, perhitungan kimia

The aims of this research were to develop student’s worksheet based on metacognitive strategy in metacomprehension category on stoichiometry matter, to describe its feasibility and to know student’s response to the worksheet developed. This research method used 4-D model but only three steps were done (3-models), such as define, design, and develop. This research target was student worksheet based on metacognitive strategy especially in metacomprehension category on stoichiometry matter. The trial of student worksheet was done limited to 20 students in XI grade of SMA Negeri 2 Lamongan. The result showed that student worksheet were developed with feasibility score for each components, such as component aspect of worksheet, presentation of worksheet, content of worksheet, suitability with language component, and suitability with metacomprehension criterion with the score continuously are 83.33%, 80%, 86.67%, 85%, 80% and 97% which categorized as good. And students responded positively to the worksheet with score is ≥ 61% for each aspect, with the score for each aspect continuously are 97%, 92%, 100%, and 97%.

Key words: student worksheet based on metacognitive strategy, metacomprehension,    stoichiometry
