PENGEMBANGAN E-LKPD BERBASIS INKUIRI TERBIMBING PADA MATERI PERTUMBUHAN DAN PERKEMBANGAN  TUMBUHAN UNTUK MELATIHKAN KEMAMPUAN BERPIKIR KRITIS SISWA

KELAS XII SMA

DEVELOPMENT OF E-LKPD BASED ON GUIDED INQUIRY ON PLANT GROWTH AND DEVELOPMENT MATERIAL TO TRAIN STUDENTS' CRITICAL THINKING SKILLS CLASS XII SMA

Seiring berkembangnya zaman tuntutan pendidikan semakin pesat, siswa dituntut untuk menguasai teknologi dan keterampilan 4C agar dapat bersaing di era ke-21. Salah satu keterampilan 4C yang dibutuhkan siswa adalah berpikir kritis. Keterampilan berpikir kritis dapat dilatihkan melalui penggunaan E-LKPD  berbasis Inkuiri terbimbing sebagai jawaban dari perkembangan teknologi. Penelitian ini bertujuan untuk menghasilkan E-LKPD berbasis inkuiri terbimbing untuk melatih kemampuan berpikir kritis siswa yang layak berdasarkan validitas, kepraktisan, dan keefektivan. Metode yang digunakan yaitu lembar validasi, angket respons, dan lembar tes. Validitas E-LKPD dinilai oleh dua validator ,yakni dosen ahli pendidikan dan dosen ahli materi. Kepraktisan E-LKPD diukur berdasarkan data hasil pengamatan keterlaksanaan aktivitas pembelajaran, sedangkan keefektivan diukur melalui data hasil belajar siswa kelas XII yang diperoleh melalui pengerjaan penilaian akhir E-LKPD dan ketercapaian indikator berpikir kritis. Tahap uji coba dilakukan terhadap 20 siswa kelas XII MIPA di SMA Ta’miriyah Surabaya. Berdasarkan hasil penelitian menunjukkan bahwa E-LKPD yang dikembangkan sangat valid dengan skor validitas dari kedua validator 97,33%, kepraktisan E-LKPD dinyatakan sangat praktis dengan skor pengamatan keterlaksanaan aktivitas pembelajaran mencapai 97,15% dan respons siswa mencapai 97,6%, keefektivan E-LKPD dinyatakan sangat efektiv dengan persentase ketuntasan penilaian akhir E-LKPD mencapai 100%. Dengan demikian, dapat dinyatakan bahwa E-LKPD berbasis inkuiri terbimbing untuk melatih kemampuan berpikir kritis siswa layak digunakan dalam pembelajaran berdasrkan validitas, kepraktisan, dan keefektivan.

As the times develop, the demands of education are increasing rapidly, students are required to master technology and 4C skills in order to compete in the 21st era. One of the 4C skills that students need is critical thinking. Critical thinking skills can be trained through the use of E-LKPD based on guided inquiry as an answer to technological developments. This study aims to produce guided inquiry-based E-LKPD to train students' critical thinking skills that are feasible based on validity, practicality, and effectiveness. The methods used were validation sheet, response questionnaire, and test sheet. The validity of the E-LKPD was assessed by two validators, namely educational expert lecturers and material expert lecturers. The practicality of the E-LKPD was measured based on data from observations of the implementation of learning activities, while the effectiveness was measured through data on the learning outcomes of class XII students obtained through the E-LKPD final assessment and the achievement of critical thinking indicators. The trial phase was conducted on 20 students of class XII MIPA at SMA Ta'miriyah Surabaya. Based on the results of the study, it shows that the E-LKPD developed is very valid with a validity score from both validators of 97.33%, the practicality of E-LKPD is declared very practical with the observation score of the implementation of learning activities reaching 97.15% and student responses reaching 97.6%, the effectiveness of E-LKPD is declared very effective with the percentage of completeness of the final assessment of E-LKPD reaching 100%. Thus, it can be stated that the E-LKPD based on guided inquiry to train students' critical thinking skills is feasible to use in learning based on validity, practicality, and effectiveness.
