PENGEMBANGAN LKPD BERBASIS INQUIRY UNTUK MELATIHKAN HIGH ORDER THINKING SKILL (HOTS) PADA MATERI LAJU REAKSI

DEVELOPMENT OF INQUIRY STUDENT WORKSHEET TO TRAIN HIGH ORDER THINKING SKIL (HOTS)

 IN RATE REACTION

    Penelitian ini memiliki tujuan untuk mendeskripsikan kelayakan LKPD berbasis inquiry untuk melatihkan High Order Thinking Skill (HOTS) pada Materi Laju Reaksi. Pada penelitian ini digunakan metode penelitian model 4-D (Define, Design, Develop, Dissiminate). Namun pada penelitian ini hanya dilakukan sampai tahap Develop. Selanjutnya dilakukan uji coba terbatas pada 12 peserta didik kelas XI di SMAN 1 Krian. Instrumen penelitian menggunakan lembar telaah, lembar validasi, lembar angket respon, lembar tes hasil belajar ranah pengetahuan dan lembar soal pretets-posttest HOTS. Kelayakan LKPD ditinjau berdasarkan 3 kriteria yakni validitas dari hasil validasi oleh validator, kepraktisan dari respon peserta didik dan keefektifan dari tes hasil belajar ranah pengetahuan dan hasil pretest-postttest HOTS. Analisis data menggunakan metode deskriptif kuantitatif. Hasil yang diperoleh menunjukkan presentase validitas LKPD untuk kriteria isi, kebahasaan, kepraktisan dan keefektifan sebesar 86,2%, 87,8%, 88,4% dan 91,3% dengan kategori sangat valid. LKPD yang dikembangkan mendapatkan respon yang sangat positif dengan mendapat presentase sebesar 92,2% dan dinyatakan sangat praktif. Hasil peningkatan HOTS peserta didik digambarkan dengan perolehan score n-gain sebesar 0,71 dengan kategori tinggi. Pada setiap komponen HOTS meliputi menganalisis (C4) sebesar 82,5%, mengevaluasi (C5) sebesar 81% dan mencipta (C6) sebesar 91,3% dengan kategori tinggi dan dinyatakan efektif.

This study aims to describe the feasibility of Students’ Worksheet using inquiry-based to train High Order Thinking Skill (HOTS) on the Reaction Rate Material. The research method used is the 4-D model (Define, Design, Develop, Disseminate), but in this study it only reaches the stage Develop. Furthermore, a limited trial was carried out on 12 students of class XI at SMAN 1 Krian. The research instrument consisted of a review sheet, a validation sheet, a response questionnaire, a test sheet for learning outcomes in the domain of knowledge and a HOTS pretets-posttest question sheet. The feasibility of Students’ Worksheet is reviewed based on 3 criteria, as the validity of the validation results by the validator, the practicality of the students' responses and the effectiveness of the learning outcomes test in the realm of knowledge and the HOTS pretest-posttest results. Data analysis using quantitative descriptive method. The results obtained showed the percentage of Students’ Worksheet validity for content, language, practicality and effectiveness criteria of 86.2%, 87.8%, 88.4% and 91.3% with very valid categories. The developed Students’ Worksheet received a very positive response with a percentage of 92.2% and was stated to be very practive. The results of the increase in HOTS of students are described by the acquisition of an n-gain score of 0.71 in the high category. Each HOTS component includes analyzing (C4) of 82.5%, evaluating (C5) of 81% and creating (C6) of 91.3% in the high category and declared effective.
