Berpikir kritis merupakan salah satu kemampuan yang sangat dibutuhkan peserta didik pada abad ke-21. Kemampuan berpikir kritis dapat dilatih melalui kegiatan berbasis literasi sains dalam pembelajaran. Penelitian ini bertujuan untuk menghasilkan E-LKPD berbasis literasi sains pada sub-materi tumbuhan lumut dan tumbuhan paku untuk melatih kemampuan berpikir kritis peserta didik yang valid, praktis, dan efektif. Penelitian menggunakan metode 4D terdiri dari define, design, develop, dan disseminate. Uji coba dilakukan di SMA Muhammadiyah 1 Taman dan melibatkan 26 peserta didik kelas X-3. Variabel penelitian mencakup hasil validitas, kegiatan peserta didik, respons peserta didik, dan hasil belajar dari pre-test dan post-test untuk mengetahui kemampuan berpikir kritis dan ketuntasannya. Indikator berpikir kritis yang diukur berupa inferring, advanced clarification, dan strategies and tactics. Hasil validitas E-LKPD sebesar 92,69% kategori sangat valid. Hasil kepraktisan berdasarkan keterlaksanaan sebesar 93% dengan kategori sangat praktis dan respons peserta didik sebesar 85% dengan kategori praktis. Hasil keefektifan E-LKPD dengan n-gain sebesar 0,68 kategori sedang dan ketercapaian indikator berpikir kritis inferring 83%, advanced clarification 75%, dan strategies and tactics 78%. E-LKPD berbasis literasi sains dinyatakan layak digunakan dari segi validitas, kepraktisan, dan keefektifan untuk melatih kemampuan berpikir kritis peserta didik.

Critical thinking is one of the most needed skills for students in the 21^st century. Critical thinking skills can be trained by activities with scientific literacy base in the class. The aim for this research is develop scientific literacy-based E-Worksheet on Bryophythes and Pteridophytes sub-materials to train students’ critical thinking which is proper to use in class based on validity, practicality, and effectiveness. This research use 4D developing research consist of define, design, develop, and disseminate. Research trials have been done in SMA Muhammadiyah 1 Taman and involved 26 students of class X-3. The research variables consist of validity of expert validators results, practicality of student activities and student responses, and efficacy of student outcomes to know their critical thinking levels and their completeness. The collected data were analyzed using a quantitative descriptive techniques. The E-Worksheet validity was obtained by two validators in percentage of 92.96% with very valid categorized. The E-Worksheet practicality on implementation test get 93% score with very practical categorized and student responses questionnaire get 85% score with practical categorized. The effectiveness was obtained by pre-test and post-test on n-gain score was 0.64 with medium categorized and achievement of critical thinking indicators which the inferring was 85%, advanced clarification was 75%, and strategies and tactics was 78%. Based on the results, the E-Worksheet based on scientific literacy is proper based on validity, practicality, and effectiveness to train students’ critical thinking.
