PENGEMBANGAN LEMBAR KERJA PESERTA DIDIK (LKPD) BERPENDEKATAN CONTEXTUAL TEACHING AND LEARNING (CTL) UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS RESPONSIBILITY PESERTA DIDIK PADA MATERI TERMOKIMIA

DEVELOPMENT OF STUDENT WORKSHEETS WITH CONTEXTUAL TEACHING AND LEARNING (CTL) APPROACH TO TRAIN CRITICAL THINKING SKILLS RESPONSIBILITY OF STUDENTS ON THERMOCHEMICAL MATERIALS

Penelitian ini bertujuan untuk menghasilkan dan mendeskripsikan kelayakan LKPD berpendekatan Contextual Teaching and Learning (CTL) dalam melatih keterampilan berpikir kritis responsibility pada materi termokimia. Penelitian ini menggunakan jenis penelitian Research and Development (R&D) yang mengacu pada model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Sampel penelitian adalah 24 peserta didik kelas XI IPA MA Nurut Taqwa Grujugan Cermee Bondowoso. Hasil penelitian menunjukkan bahwa: 1) Analisis kevalidan memperoleh persentase rata-rata sebesar 87% dengan kriteria sangat valid; 2) Analisis kepraktisan berdasarkan persentase angket respon dan observasi aktivitas peserta didik sebesar 88% dan 98% dengan kriteria sangat praktis; 3) Analisis keefektifan berdasarkan data pretest-posttest: a) Uji normalitas pengetahuan kognitif dan keterampulan berpikir kritis 0,985 dan 0,297 berdistribusi normal; b) Uji Paired Sample t-Test 0,000 menunjukkan adanya peningkatan hasil belajar; c) Uji N-Gain pengetahuan kognitif dan keterampilan berpikir kritis memperoleh nilai 93% dan 79% menunjukkan adanya peningkatan hasil belajar dan sikap responsibility memperoleh skor 87% dengan kriteria sangat baik. Maka dapat disimpulkan bahwa pengembangan LKPD berpendekatan Contextual Teaching and Learning (CTL) dikategorikan layak dengan kriteria sangat valid, praktis dan efektif. Pengembangan LKPD sebagai bahan ajar untuk meningkatkan keterampilan berpikir kritis responsibility peserta didik menjadi alternatif pilihan pembelajaran belajar menjadi lebih bermakna diiringi sikap siswa yang penuh tanggung jawab menjadi suatu hal yang penting untuk dilakukan.

This study aims to produce and describe the feasibility of Student Worksheet with a Contextual Teaching and Learning (CTL) approach in training critical thinking skills and responsibility in thermochemical material. This study uses a Research and Development (R&D) type which refers to the ADDIE (Analysis, Design, Development, Implementation, Evaluation). The research sample was 24 students of class XI IPA MA Nurut Taqwa Grujugan Cermee Bondowoso. The results showed that: 1) Validity analysis obtained an average percentage of 87% with very valid criteria; 2) Practical analysis based on the percentage of response questionnaires and student activity observations of 88% and 98% with very practical criteria; 3) Analysis of effectiveness based on pretest-posttest data: a) Normality test of cognitive knowledge and critical thinking skills 0.985 and 0.297 normally distributed; b) Paired Sample t-Test 0.000 showed an increase in learning outcomes; c) The N-Gain test of cognitive knowledge and critical thinking skills scored 93% and 79% showed an increase in learning outcomes and attitude of responsibility obtained a score of 87% with very good criteria. So it can be concluded that the development of Student Worksheet with a Contextual Teaching and Learning (CTL) approach is categorized as feasible with very valid, practical and effective criteria. The development of Student Worksheet as a teaching material to improve students' critical thinking skills, become an alternative choice for learning to make learning more meaningful, accompanied by the attitude of students who are full of responsibility, which is an important thing to do.
