Kata Kunci: E-LKPD, Isu Sosio-saintifik (SSI), berpikir kritis

Perkembangan teknologi telah mempengaruhi seluruh aspek kehidupan, termasuk pendidikan. Kemajuan teknologi menuntut masyarakat untuk melek teknologi. Selain itu, terjadinya pandemi covid 19 juga mengharuskan pembelajaran dilaksanakan secara dalam jaringan (daring). Hal ini menuntut guru untuk dapat mengembangkan bahan ajar yang dapat diakses dengan mudah oleh siswa selama proses pembelajaran. Proses pembelajaran juga harus mendukung tercapainya keterampilan abad 21, salah satunya keterampilan berpikir kritis. Pembelajaran berbasis SSI dapat melatihkan kemampuan berpikir kritis. Penelitian ini bertujuan untuk menghasilkan Lembar Kerja Peserta Didik Elektronik (E-LKPD) berbasis isu sosio-saintifik (SSI) materi pencemaran lingkungan untuk melatihkan kemampuan berpikir kritis siswa kelas VII yang layak berdasarkan validitas, kepraktisan, dan keefektifan. E-LKPD dikembangkan menggunakan model pengembangan 4D. Implementasi dilakukan terhadap tiga rombongan belajar kelas VII menggunakan One-Group Pretest-Posttest Design. Pengumpulan data menggunakan teknik validasi, observasi, tes, dan angket. Validitas perangkat yang dikembangkan ditinjau dari hasil validasi RPP, E-LKPD, dan instrumen tes kemampuan berpikir kritis oleh ahli. Kepraktisan ditinjau dari keterlaksanaan RPP, aktivitas peserta didik, dan kendala-kendala pembelajaran yang ditemui. Keefektifan ditinjau dari peningkatan kemampuan berpikir kritis dan respon peserta didik terhadap pembelajaran. Data dianalisis baik secara kuantitatif maupn kualitatif. Hasil penelitian menunjukkan validitas RPP berkategori sangat valid dengan rata-rata skor 3,82 dan kelayakan 95,59%. Validitas E-LKPD berkategori sangat valid dengan skor rata-rata 3,73 dan kelayakan 93,25%. Validitas instrumen tes kemampuan berpikir kritis adalah 3,58 dan kategori valid dengan kelayakan 89,39%. Keterlaksanaan RPP di kelas VII-1, VII-3, dan VII-4 berturut-turut adalah 93,05%; 90,83%; dan 89,17%. Aktivitas peserta didik kelas VII-1, VII-3, dan VII-4 selama pembelajaran berturut-turut 88,69%; 88,09%; dan 86,31%. Kendala pembelajaran tidak berkategori krusial dan masih dapat diatasi. Peningkatan kemampuan berpikir kritis peserta didik kelas VII-1, VII-3, dan VII-4 termasuk signifikan kategori sedang dengan skor N-Gain berturut-turut sebesar 0,48; 0,52; dan 0,51. Respon peserta didik kelas VII-1, VII-3, dan VII-4 terhadap pembelajaran termasuk sangat baik berturut-turut 90,00%; 86,50%; dan 84,06%. Berdasarkan hasil yang diperoleh, maka E-LKPD yang dikembangkan dinyatakan layak untuk digunakan dalam pembelajaran untuk melatihkan kemampuan berpikir kritis.

Keywords: Electronic Student Worksheet, socio-scientific issue (SSI), critical thinking.

The developments of technology have affected all aspects of life, including education. Advances in technology require people to have technology literacy. In addition, the occurrence of the COVID-19 pandemic also requires learning to be carried out online. This requires teachers to be able to develop teaching materials that can be accessed easily by students during the learning process. The learning process must also support the achievement of 21st century skills, one of which is critical thinking skills. SSI-based learning can train critical thinking skills. The purpose of this study was to produce an Electronic Student Worksheet based on socio-scientific issues (SSI) on the topic of environmental pollution to train students of grade VII critical thinking skills based on validity, practicality, and effectiveness. Electronic student worksheet was developed using a 4D development model. The trial was conducted with three class VII students using the One-Group Pretest-Posttest Design. Data collection techniques used validation, observation, test, and questionnaire. The validity of the developed device was reviewed from the results of the validation of the lesson plans, electronic student worksheet, and critical thinking ability test instruments by experts. Practicality was reviewed from the implementation of lesson plans, student activities, and learning obstacles encountered. Effectiveness was reviewed from increasing critical thinking skills and student responses to learning. Data were analyzed both quantitatively and qualitatively. The results showed that the validity of the lesson plan was categorized as very valid with an average score of 3.82 and 95.59% feasibility. The validity of the electronic student worksheet was categorized as very valid with an average score of 3.73 and the feasibility of 93.25%. The validity of the critical thinking ability test instrument was 3.58 and the category was valid with 89.39% feasibility. The implementation of lesson plans in grades VII-1, VII-3, and VII-4 respectively were 93.05%; 90.83%; and 89.17%. The activities of students in grades VII-1, VII-3, and VII-4 during learning respectively were 88.69%; 88.09%; and 86.31%. Learning barriers were not categorized as crucial and can still be overcome. The improvement in critical thinking skills of students in grades VII-1, VII-3, and VII-4 was significant in the moderate category with a consecutive N-Gain score of 0.48; 0.52; and 0.51. The responses of students in grades VII-1, VII-3, and VII-4 to learning were very good, respectively, 90.00%; 86.50%; and 84.06%. Based on the results obtained, the developed electronic student worksheet was declared feasible to be used in learning to practice critical thinking skills.
