PENGEMBANGAN E-LKPD BERBASIS PROBLEM BASED LEARNING UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS PADA MATERI HEREDITAS MANUSIA

Development of Problem Based Learning Based E-LKPD to Train Critical Thinking Skills in Human Heredity Topic

Kurikulum 2013 mengharuskan peserta didik untuk berperan aktif dalam proses pembelajaran. Salah satu model pembelajaran yang relevan untuk diterapkan pada kurikulum 2013 adalah Problem Based Learning (PBL), karena berorientasi student-centered learning dan memfasilitasi keterampilan berpikir kritis. Tujuan penelitian ini menghasilkan e-LKPD berbasis PBL untuk melatihkan keterampilan berpikir kritis pada materi hereditas manusia yang layak berdasarkan validitas, kepraktisan, dan keefektifan. Model penelitian ini mengacu pada model 4D (Define, Design, Develop, dan Disseminate). Data didapatkan menggunakan metode validasi, observasi, tes, dan angket respon. Data validasi didapatkan melalui lembar validasi, data kepraktisan didapatkan dari hasil observasi keterlaksanaan, dan data keefektifan didapatkan dari hasil tes, ketercapaian indikator, dan respon peserta didik. Data tersebut dianalisis secara deskriptif kuantitatif. Hasil analisis menandakan bahwa e-LKPD memperoleh validitas dengan kategori sangat valid sebesar 97.8%. Hasil kepraktisan mendapatkan persentase dengan kategori sangat praktis sebesar 93.09%, dan keefektifan mendapatkan beberapa hasil yaitu ketuntasan hasil tes sebesar 100%, ketercapaian indikator keterampilan berpikir kritis sebesar 85.6% dan respon positif peserta didik sebesar 97.76%. Dengan demikian, e-LKPD berbasis PBL pada materi hereditas manusia yang dihasilkan dinyatakan valid, praktis, dan efektif digunakan sebagai bahan ajar dalam pembelajaran serta mampu melatihkan keterampilan berpikir kritis.

Curriculum 2013 requires learners to have an active role in every activity in learning process. One of the relevant learning models to be applied to the 2013 curriculum is Problem Based Learning (PBL), because it is oriented towards student-centered learning and facilitates critical thinking skills. The purpose of this research is to produce e-LKPD based on PBL to practice critical thinking skills on appropriate human heredity topic based on validity, practicality, and effectiveness. This research refers to a 4D model development (Define, Design, Develop, and Disseminate). The results were obtained uses validation, observation, test, and questionnaire methods. Data was obtained with a validation sheet, practicality was obtained from the results of observations of implementation, and effectiveness was obtained from test results, the achievement of indicators, and the response of learners. The data obtained is analyzed descriptively quantitatively. The results of the analysis indicated that e-LKPD obtained validity with a very valid category of 97.8%. Practicality results got a percentage with a very practical category of 93.09%, and the effectiveness got several results include completeness of test results of 100%, achievement of critical thinking skills indicators of 85.6% and positive student responses of 97.76%. Thus, PBL based e-LKPD in human heredity topic produced is declared valid, practical, and effective for as teaching materials in learning and is able to train critical thinking skills.
