Pengembangan E-LKPD Berbasis Pendekatan Konstruktivisme Pada Submateri Pembelahan Sel Untuk Melatihkan Keterampilan Berpikir Kritis Siswa Kelas XI

Development Of E-LKPD Based On A Constructivism Approach On Cell Division Submatter To Train Critical Thinking Skills In Class XI Students

Keterampilan berpikir kritis diperlukan dalam meningkatkan kualitas pendidikan abad ke-21 di Indonesia. Penelitian ini bertujuan menghasilkan e-LKPD berbasis pendekatan konstruktivisme pada sub materi pembelahan sel untuk melatihkan keterampilan berpikir kritis siswa SMA Kelas XI yang valid, praktis, dan efektif. E-LKPD berbasis pendekatan konstruktivisme adalah e-LKPD yang dibuat menggunakan media liveworksheet yang dapat langsung digunakan untuk menjawab soal, menonton video agar tampilan lebih menarik dan interaktif. Penelitian ini menggunakan model pengembangan 4D (Define, Design, Develop, Disseminate). Validasi e-LKPD dinilai berdasarkan validasi oleh dosen ahli pendidikan, dosen ahli materi, dan guru biologi. Kepraktisan e-LKPD diukur berdasarkan keterlaksanaan dan angket respon peserta didik mengenai kegiatan dan penggunaan e-LKPD selama pembelajaran. Keefektifan e-LKPD diukur berdasarkan hasil belajar kognitif dan ketercapaian kemampuan berpikir kritis menggunakan pretest dan posttest. Penelitian ini diujicobakan pada 20 siswa kelas F11.4 SMA Hang Tuah 1 Surabaya. Hasil penelitian menunjukkan e-LKPD berbasis pendekatan konstruktivisme dinyatakan valid dengan skor 3,81. E-LKPD dinyatakan praktis dengan hasil uji keterlaksanaan dengan persentase 98% dan hasil uji respon peserta didik dengan persentase 97,8%. E-LKPD dinyatakan efektif dengan rerata persentase hasil belajar kognitif dan keterampilan berpikir kritis berturut-turut yaitu 100% tuntas dan 91% baik dengan rata-rata N-Gain sebesar 0,73 dengan kategori peningkatan tinggi. Berdasarkan hasil tersebut, dapat disimpulkan bahwa e-LKPD yang dikembangkan berbasis pendekatan konstruktivisme valid, praktis, dan efektif untuk melatihkan kemampuan berpikir kritis peserta didik pada sub materi pembelahan sel kelas XI SMA.

Critical thinking skills are needed to improve the quality of 21st century education in Indonesia. This study aims to produce e-LKPD based on constructivism approach on cell division sub-material to train critical thinking skills of Class XI high school students that are valid, practical, and effective. E-LKPD based on constructivism approach is an e-LKPD made using liveworksheet media that can be directly used to answer questions, watch videos to make the display more interesting and interactive. This research uses the 4D development model (Define, Design, Develop, Disseminate). The validation of e-LKPD was assessed based on validation by education expert lecturers, material expert lecturers, and biology teachers. The practicality of e-LKPD was measured based on the implementation and response questionnaire of students regarding the activities and use of e-LKPD during learning. The effectiveness of e-LKPD was measured based on cognitive learning outcomes and the achievement of critical thinking skills using pretest and posttest. This research was tested on 20 students of class F11.4 SMA Hang Tuah 1 Surabaya. The results showed that the e-LKPD based on the constructivism approach was declared valid with a score of 3.81. E-LKPD is declared practical with the results of the implementation test with a percentage of 98% and the results of the student response test with a percentage of 97.8%. E-LKPD is declared effective with the average percentage of cognitive learning outcomes and critical thinking skills respectively, namely 100% complete and 91% good with an average N-Gain of 0.73 with a high improvement category. Based on these results, it can be concluded that the e-LKPD developed based on the constructivism approach is valid, practical, and effective for training students' critical thinking skills on cell division sub-material in class XI SMA.
