Pengembangan E-LKPD Berbasis Contextual Teaching And Learning Untuk Melatihkan Keterampilan Berpikir Kritis Pada Materi Keanekaragaman Hayati

The Development of E-LKPD Based on Contextual Teaching and Learning to Train Critical Thinking Skills on Biodiversity

Pentingnya keterampilan berpikir kritis pada abad ke-21 dapat diperluas melalui pendekatan contextual teaching and learning yang mengintegrasikan situasi kehidupan sehari-hari dengan materi pembelajaran. Dalam upaya melatih keterampilan berpikir kritis, digunakan bahan ajar berbasis elektronik. Penelitian ini bertujuan untuk menghasilkan lembar kerja peserta didik elektronik berbasis contextual teaching and learning untuk melatihkan keterampilan berpikir kritis pada materi keanekaragaman hayati yang valid berdasarkan hasil validasi, praktis berdasarkan hasil observasi keterlaksanaan, respons guru dan respons peserta didik serta efektif berdasarkan hasil belajar peserta didik. Penelitian menggunakan model pengembangan 4D yang terdiri dari tahap define, design, develop dan tanpa tahap disseminate. Penelitian ini dilakukan di Jurusan Biologi, UNESA, dan diujicobakan kepada 20 peserta didik dari kelas X-3 di SMAN 16 Surabaya. Instrumen penelitian yang digunakan adalah lembar validasi E-LKPD, lembar observasi keterlaksanaan, lembar angket respons guru, lembar angket respons peserta didik serta lembar penilaian pretest dan posttest. Analisis  data  dilakukan secara deskriptif  kuantitatif.  Berdasarkan hasil validasi yang ditinjau berdasarkan penyajian, isi dan bahasa, E-LKPD dinyatakan sangat valid dengan persentase 99,65% dan sangat praktis ditinjau berdasarkan hasil observasi keterlaksanaan dengan persentase 95%, respons guru dengan persentase 98,61%, respons peserta didik dengan persentase 96,84% serta sangat efektif ditinjau dari adanya peningkatan hasil belajar yang dapat dilihat dari rata-rata n-gain 0,72 dengan kategori tinggi.

The importance of critical thinking skills in the 21st century can be expanded through the contextual teaching and learning approach, which integrates real-life situations with learning materials. In the effort to cultivate critical thinking skills, electronic-based teaching materials are utilized. The validity of the worksheet is determined through validation results, its practicality is assessed based on observations of implementation, and its effectiveness is evaluated by measuring students learning outcomes. This research refers to the 4D development model, consisting of the Define, Design, Develop, and without the Disseminate stages. The research was conducted at the Department of Biology, UNESA, and tested on 20 students from class X-3 at SMAN 16 Surabaya. The research instruments used included the E-LKPD validation sheet, implementation observation sheet, teachers questionnaire, students questionnaire, pretest, and posttest assessment sheets. Data analysis was performed using descriptive quantitative research. Based on the validation results, considering the presentation, content, and language, the E-LKPD was deemed highly valid with a percentage of 99.65%. In terms of practicality, it achieved a high level of practicality with a percentage of 95% based on the implementation observation, 98.61% based on the teacher's response, and 96.84% based on the student's response. Furthermore, the worksheet was highly effective, as indicated by the significant improvement in students' learning outcomes, with an average n-gain of 0.72, which falls under the high category.Top of Form
