PENGEMBANGAN LKPD BERORIENTASI LEARNING CYCLE 7-E UNTUK MENINGKATKAN KETERAMPILAN BERPIKIR KRITIS PESERTA DIDIK PADA MATERI KESETIMBANGAN KIMIA  

DEVELOPMENT OF SETUDENT WORKSHEETS ORIENTED LEARNING CYCLE 7-E TO IMPROVE STUDENTS CRITICAL THINKING SKILLS IN CHEMICAL EQUILIBRIUM MATERIALS

Abstrak

Penelitian ini bertujuan mengembangkan Lembar Kerja Peserta Didik (LKPD) berorientasi learning cycle 7E pada materi kesetimbangan kimia yang memenuhi syarat kelayakan. Penelitian ini mengikuti desain Research and Development (R&D) namun terbatas sampai tahap uji coba produk. Subjek penelitian terdiri atas 15 peserta didik SMA Negeri 1 Kedungadem, Bojonegoro. Kelayakan LKPD ditinjau dari validitas, kepraktisan, dan keefektifan yang ditentukan menggunakan instrumen penelitian secara berturut-turut yaitu lembar validitas, lembar angket respon, dan tes hasil belajar. Hasil penelitian menunjukkan LKPD dinyatakan valid berdasarkan kriteria isi, penyajian, kegrafikan, kesesuaian model learning cycle 7E, dan kesesuaian keterampilan berpikir kritis yang memperoleh persentase secara berturut-turut adalah 82%, 85%, 85%, 88,7%, dan 87,5% kategori sangat valid. LKPD juga memenuhi syarat kepraktisan berdasarkan lembar respon peserta didik yang memperoleh rata-rata persentase sebesar 92,5% kategori sangat baik. LKPD juga dinyatakan efektif berdasarkan hasil tes pengetahuan dihitung berdasarkan n-gain score dengan perolehan persentase 63,3% kategori tinggi dan 46,7% kategori sedang dan tes keterampilan diperoleh persentase pada setiap komponen berpikir kritis yaitu, interpretasi 79,51%, analisis 86,6%, inferensi 88,3%, dan evaluasi 80,35% dengan kategori tinggi.

Abstract

This study aims to develop a learning cycle 7E-oriented Student Worksheet (LKPD) on chemical equilibrium materials that meet the eligibility requirements. This research follows the design of Research and Development (R&D) but is limited to the product trial stage. The study subject consisted of 15 students of SMA Negeri 1 Kedungadem, Bojonegoro. The feasibility of LKPD is reviewed from the validity, practicality, and effectiveness determined using successive research instruments, namely validity sheets, response questionnaires, and study results tests. The results showed LKPD declared valid based on the criteria of content, presentation, graphing, conformity of learning cycle 7E model, and conformity of critical thinking skills that obtained percentage in a row is 82%, 85%, 85%, 88.7%, and 87.5% categories are very valid. LKPD also qualified for practicality based on the response sheet of students who obtained an average percentage of 92.5% of the excellent category. LKPD was also declared effective based on knowledge test results calculated based on n-gain score with a percentage gain of 63.3% high category and 46.7% moderate category and skill test obtained percentage on each critical thinking component i.e., interpretation of 79.51%, analysis of 86.6%, inference of 88.3%, and evaluation of 80.35% with high category.
