Pengembangan E-LKPD Berbasis Guided Inquiry pada Materi Fotosintesis untuk Melatihkan Keterampilan Proses Sains Terintegrasi Siswa Kelas XII SMA

The Development of Electronic Student Worksheet Based Guided Inquiry on Photosynthesis Topic to Train Integrated Science Process Skills for 12^th Grade Senior High School Students

Abstrak

Pembelajaran biologi mengajarkan peserta didik mempelajari alam secara ilmiah dan sistematis melalui proses inkuiri, sehingga dapat mengembangkan keterampilan proses sains terintegrasi. Karena itu, diperlukan penerapan keterampilan proses sains terintegrasi dalam pembelajaran yang didukung dengan model guided inquiry melalui bahan ajar inovatif berupa lembar kegiatan peserta didik elektronik (E-LKPD). Penelitian ini bertujuan menghasilkan E-LKPD berbasis guided inquiry pada materi fotosintesis untuk melatihkan keterampilan proses sains terintegrasi peserta didik kelas XII SMA yang valid, praktis, dan efektif. Penelitian ini menggunakan model pengembangan 4D (define, design, develop, dan disseminate). Validitas E-LKPD dinilai berdasarkan validasi oleh pakar Pendidikan Biologi. Kepraktisan E-LKPD diperoleh dari hasil observasi keterlaksanaan aktivitas peserta didik menggunakan E-LKPD selama pembelajaran. Keefektifan E-LKPD diukur berdasarkan tes keterampilan proses sains terintegrasi menggunakan pretest-posttest dan respons peserta didik. Data dianalisis secara deskriptif kualitatif dan kuantitatif. Hasil penelitian menunjukkan E-LKPD dinyatakan sangat valid dengan skor 98,40%. E-LKPD dinyatakan sangat praktis dengan skor 96,92%. E-LKPD dinyatakan sangat efektif dengan skor ketercapaian indikator keterampilan proses sains terintegrasi sebesar 88% dan respons positif sebesar 97,95%. Disimpulkan bahwa E-LKPD yang dikembangkan dinyatakan valid, praktis, dan efektif digunakan dalam pembelajaran.

Abstract

Biology learning teaches students how to investigate nature scientifically and systematically through a process of inquiry, so they can develop integrated science process skills. As a result, integrated science process skills must be applied in learning supported by a guided inquiry model through innovative teaching materials such as electronic student worksheet (E-LKPD). This research aims to produce an E-LKPD based guided inquiry on photosynthesis topic to train integrated science process skills for 12^th grade senior high school students that are valid, practical, and effective. This research uses a 4D development model (define, design, develop, and disseminate). The validity of E-LKPD was assessed based on the results of validation by Biology Education experts. The practicality of E-LKPD was obtained from the observations of implementing student activities using E-LKPD during learning. The effectiveness of E-LKPD was measured based on integrated science process skills tests using pretest-posttest and student responses. Data were analyzed in descriptive qualitative and quantitative. The results showed that E-LKPD was declared very valid with a score of 98.40%. E-LKPD was declared very practical with a score of 96.92%. E-LKPD was declared very effective with an integrated science process skill indicator achievement score of 88% and a positive response score of 97.95%. It concluded that the developed E-LKPD is declared valid, practical, and effective for use in learning.
