PENGEMBANGAN LKPD ELEKTRONIK BERBASIS PENDEKATAN SAINTIFIK UNTUK MELATIHKAN KETERAMPILAN BERPIKIR KRITIS PADA MATERI TRANSPOR MEMBRAN

DEVELOPMENT OF ELECTRONIC WORKSHEET BASED ON SCIENTIFIC APPROACH TO TRAIN CRITICAL THINKING SKILLS ON MEMBRANE TRANSPORT TOPIC

Pada abad 21 ini, peserta didik perlu untuk menguasai keterampilan yang dapat membantunya menghadapi era yang penuh tantangan. Salah satu keterampilan tersebut adalah keterampilan berpikir kritis. Keterampilan berpikir kritis peserta didik dapat dilatihkan dengan melakukan inovasi bahan ajar yang terintegrasi dengan pendekatan saintifik. Penelitian ini bertujuan untuk menghasilkan LKPD Elektronik berbasis pendekatan saintifik yang dapat melatihkan keterampilan berpikir kritis pada materi transpor membran yang valid, praktis, dan efektif. Penelitian pengembangan ini menggunakan model pengembangan 4-D (Define, Design, Develop, Disseminate). Parameter yang diukur yaitu validitas, kepraktisan, dan keefektifan. Analisis data menggunakan teknik deskriptif kuantitatif. Validitas LKPD Elektronik dinilai oleh 3 validator dan memperoleh rata-rata persentase sebesar 3,69 dengan kategori sangat valid. Kepraktisan ditentukan berdasarkan hasil observasi oleh 4 orang pengamat selama pelaksanaan LKPD Elektronik dan memperoleh rata-rata persentase sebesar 93,28% dengan kategori sangat praktis. Keefektifan ditentukan berdasarkan penilaian hasil belajar mendapatkan skor ketuntasan post test sebesar 83,33% dengan kategori sangat efektif, N-gain score sebesar 0,69 dengan kategori sedang, rata-rata ketuntasan tiap indikator berpikir kritis sebesar 80,18% serta respon peserta didik memperoleh rata-rata persentase sebesar 98,14% yang termasuk dalam kategori sangat efektif. LKPD Elektronik layak digunakan pada kelas XI SMA berdasarkan aspek validitas, kepraktisan, dan keefektifan. LKPD Elektronik yang telah dikembangkan dapat memperkaya bahan ajar alternatif di sekolah.

In this 21^st century, students need to be mastered with skills that help them face this challenging era. One of the skills is critical thinking skills. Students’ critical thinking skills can be train by innovating teaching materials which integrated with scientific approach. This study aims to produce Electronic Worksheets based on a scientific approach to train critical thinking skills on membrane transport materials that are valid, practical, and effective. This development uses the 4-D development model (Define, Design, Develop, Disseminate). The parameters measured were validity, practicality, and effectiveness. The data analysis was using quantitative descriptive techniques. The validity of the electronic worksheet was assessed by 3 validators and obtained an average percentage of 3.69 with a very valid category. Practicality was determined based on the results of observations conducted by 4 observers during the implementation of Electronic Worksheet which got an average percentage of 93.28% in the very practical category. Effectiveness was determined based on the assessment of learning outcomes and got a post-test completeness score of 83.33% in the very effective category, the N-gain score was 0.69 in the moderate category, the average completeness of each critical thinking indicator was 80.18%, and in terms of student responses got an average percentage of 98.14% which was included in the very effective category. Electronic Worksheet is suitable for use at class XI SMA based on the aspects of validity, practicality, and effectiveness. Electronic Worksheet that has been developed can enrich alternative teaching materials in schools.
