Pengembangan E-LKPD Virus Berbasis Problem Based Learning untuk Melatihkan Keterampilan Berpikir Kritis Siswa Kelas X 

Development of Problem Based Learning Based Virus E-LKPD to Train Critical Thinking Skills for 10th Grade Student

Pandemi COVID-19 mengubah sistem pendidikan di Indonesia menjadi sistem pembelajaran online. Sebagai pendidik, guru harus mampu memahami situasi dan menyiapkan bahan ajar yang cocok digunakan agar pembelajaran dapat terus berjalan secara optimal. Salah satu bahan ajar yang cocok digunakan saat pembelajaran online yaitu E-LKPD. Penelitian ini bertujuan untuk menghasilkan bahan ajar berupa E-LKPD virus berbasis Problem Based Learning (PBL) untuk melatihkan keterampilan berpikir kritis siswa kelas X yang valid, praktis dan efektif. Penelitian ini menggunakan metode penelitian pengembangan dengan model 4-D yang terdiri atas Define, Design, Develope dan Disseminate. Parameter yang diukur yaitu validitas, keefektifan dan kepraktisan. Validitas E-LKPD dinilai dengan menggunakan instrumen lembar validasi yang dilakukan oleh dosen ahli materi, dosen ahli pendidikan dan satu guru Biologi SMA. Keefektifan diukur menggunakan hasil pretest dan post-test yang kemudian dianalisis menggunakan N-gain score serta analisis ketercapaian aspek berpikir kritis. Sedangkan kepraktisan E-LKPD didapatkan melalui hasil respon siswa menggunakan angket respon siswa. Hasil validasi E-LKPD memperoleh persentase sebesar 89,25% yang dikategorikan sangat valid. Hasil keefektifan memperoleh N-gain score sebesar 0,84 dengan kriteria tinggi dan ketercapaian aspek berpikir kritis dengan persentase sebesar 94,18% yang dikategorikan sangat kritis. Sedangkan kepraktisan mendapatkan persentase 99% yang dikategorikan sangat praktis. Dari hasil penelitian dapat disimpulkan bahwa E-LKPD virus berbasis PBL untuk melatih keterampilan berpikir kritis dinyatakan sangat valid, praktis dan efektif sebagai bahan ajar untuk kelas X SMA. Dengan menggunakan E-LKPD virus berbasis PBL dapat melatihkan dan meningkatkan keterampilan berpikir kritis siswa, serta mengetahui penguasaan siswa terhadap materi virus. Selain itu pengembangan E-LKPD juga bisa diterapkan pada materi yang lain

The COVID-19 pandemic has changed the education system in Indonesia into an online learning system. As educators, teachers must be able to understand the situation and prepare teaching materials that are suitable so that learning kept running by optimally. One of the suitable teaching materials for online learning is E-LKPD. This research aims to produce teaching materials in the form of the form of Problem Based Learning (PBL)-based virus E-LKPD to train the critical thinking skills of class 10th students that are valid, practical, and effective. This study used a development research method with a 4-D model consisting of Define, Design, Develop and Disseminate. The parameters measured were validity, effectiveness, and practically. The validity of the E-LKPD was assess using a validation sheet instrument which was carried out by material expert lecturers, education expert lecturers, and one high school Biologi teacher. The effectiveness was measured using the results of pretest and post-test of students which was then analyzed using the N-gain score and analysis of the achievement of critical thinking aspects. While the practicality of E-LKPD was obtained through the results of student responses using student response questionnaires. The results of the E-LKPD validation obtained a percentage of 89.25% was categorized as very valid. The effectiveness of getting an N-gain score of 0.84 with high criteria and the achievement of critical thinking aspects with a percentage of 94.18% was categorized as very critical. While practicality gets a percentage of 99% which was categorized as very practical. From the research results, it can be conclude that the form of PBL-based virus E-LKPD to train critical thinking skills is state to be very valid, practical, and effective as teaching material for class 10th in senior high school. By using PBL-based virus E-LKPD, it can train and improve students' critical thinking skills, as well as determine students' mastery of virus material. In addition, the development of E-LKPD can also be applied to other materials
