VALIDITAS LKPD BERBASIS ARGUMENT-DRIVEN INQUIRY (ADI) MATERI STRUKTUR SEL DAN JARINGAN TUMBUHAN UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS SISWA SMA

THE VALIDITY OF STUDENT WORKSHEETS BASED ON ARGUMENT-DRIVEN INQUIRY (ADI) IN CELL STRUCTURE AND PLANT TISSUE MATERIAL TO TRAIN CRITICAL THINKING SKILL FOR SENIOR HIGH SCHOOL STUDENTS

Kemampuan berpikir kritis merupakan salah satu kompetensi abad 21 yang perlu dikuasai peserta didik dalam dunia pendidikan, sehingga perlu adanya bahan ajar yang tepat salah satunya LKPD berbasis Argument-Driven Inquiry (ADI). Argument-Driven Inquiry (ADI) adalah model pembelajaran inkuiri yang efektif dalam meningkatkan kemampuan berpikir kritis peserta didik melalui keterampilan berargumentasi. Salah satu materi pembelajaran sesuai dengan model ADI adalah struktur sel dan jaringan tumbuhan. Penelitian ini bertujuan untuk menghasilkan LKPD berbasis Argument-Driven Inquiry (ADI) pada materi struktur sel dan jaringan tumbuhan untuk melatihkan kemampuan berpikir kritis kelas IX SMA yang layak berdasarkan validitas. Metode yang digunakan dalam penelitian ini adalah model pengembangan ADDIE (Analysis, Design, Development, Implementation, dan Evaluation). Tahap yang dilakukan hanya sampai pada tahap pengembangan LKPD. Pengembangan LKPD dilakukan di Jurusan Biologi, Fakultas Matematika dan IPA, Universitas Negeri Surabaya. Validitas LKPD diperoleh dari validasi para ahli menggunakan lembar validasi. Hasil penelitian menunjukkan bahwa LKPD yang dikembangkan dinyatakan sangat valid dengan skor rata-rata sebesar 3,74. Berdasarkan data yang diperoleh, dapat disimpulkan bahwa LKPD yang dikembangkan dinyatakan layak berdasarkan validitasnya dan dapat digunakan dalam proses pembelajaran.

Critical thinking skills is one of the 21st century competencies that students need to have in education. Therefore, teaching materials must be developed in learning process, one of them is student worksheets with Argument-Driven Inquiry (ADI) based. Argument-Driven Inquiry is an inquiry learning model that effective to improving the critical thinking skill students by argumentation skill. One of the materials apropriated with ADI model is the structure plant of cells and plant tissue. This study aimed to describe the validity and produce worksheets based on Argument-Driven Inquiry in structure of plant cells and plant tissue material to train critical thinking skill for senior high school students. The method used in this research is ADDIE (Analysis, Design, Development, Implementation, and Evaluation) development model. The phase carried out only reached the stage of student worksheets development. Student worksheets development  carried out in Biology Department, Faculty of Mathematics and Natural Sciences, Surabaya State University. The validity of student worksheets obtained from the validators using the validation sheet. The results showed that the worksheets was declaring to be very valid with an average score of 3.74. Based on the data obtained, it can be concluded that student worksheets developed declared feasible based on its validity and could be used in the learning process.
