DEVELOPMENT OF LABORATORY STUDENT WORKSHEET BASED ON GUIDED INQUIRY IN THERMOCHEMISTRY TOPIC FOR XI GRADE SENIOR HIGH SCHOOL

Abstract

Tujuan dari penelitian pengembangan ini adalah untuk mengetahui kelayakan LKS ditinjau dari kelayakan isi, kelayakan penyajian, kelayakan bahasa, dan kesesuaian dengan model pembelajaran inkuiri serta melihat hasil belajar siswa dan respon siswa setelah menggunakan LKS berbasis inkuri terbimbing pada materi termokimia. Metode  penelitian yang digunakan adalah metode Research & Development (R & D) oleh Sugiyono (2010). Penelitian ini merupakan deskriptif kuantitatif dengan rancangan penelitian menggunakan“Pre-test Post-test Design”.Instrumen yang digunakan dalam penelitian ini adalah lembar telaah, lembar validasi, angket respon siswa, dan lembar soal pretest dan postes. Berdasarkan hasil penelitian, diperoleh rata-rata kelayakanisi, kelayakanpenyajian, kelayakanbahasa, dankesesuaiandengan model pembelajaran inkuiri adalah sangat baik dengan perolehan persentase berturut-turut 79%, 82,5%, 82,5%, dan 82% yang berarti LKS yang  dikembangkan layak digunakan. Hasil belajar siswa diperoleh nilai rata-rata kelas adalah 3,03dan dikatakan tuntas secara klasikalsebesar 81,25%.

Kata kunci: LKS berbasisinkuiriterbimbing, kelayakan, termokimia.

 The aims of this  development research are to know the feasibility of worksheets in terms of content feasibility, presentation feasibility, language feasibility, conformity with inquiry learning model, student mastery learning, and student respon after using the worksheets based on guided inquiry inthermochemstry topic. Research methodology which was used is Research & Development (R&D) method by Sugiyono (2010). This research is descriptive quantitative research design using "Pre-test Post-test Design". The instruments used in this research are the study sheet, validation sheet, pre-study questionnaire, student questionnaire responses, and the pretest and post-test booklet. Based on the research results, obtained an average of content feasibility, presentation feasibility, language feasibility, and conformity with inquiry learning model are very good with the acquisition of the respective percentages of 79%, 82.5%, 82.5%, and 82%. It means that worksheet that developed is very good to be used. Student mastery learning obtained an average value of 3.03 and classical mastery learning is 81.25%.
