Penelitian ini bertujuan untuk menghasilkan LKS dalam melatihkan literasi geosains siswa SMP kelas VII yang layak berdasarkan tiga aspek yakni validitas, kepraktisan, dan keefektifan. LKS berisi kegiatan yang berfokus pada tiga aspek literasi sains dan pengamatan analogi untuk melatihkan literasi geosains. Metode yang digunakan adalah R&D dan One Group Pretest-Posttest Design. Teknik pengumpulan data menggunakan metode observasi, angket, dan tes. Hasil aspek validitas ditinjau dari modus tiga syarat yakni syarat didaktik sebesar 4, syarat konstruksi sebesar 4, dan syarat teknis sebesar 3. Aspek kepraktisan ditinjau dari modus hasil keterlaksanaan pembelajaran sebesar 4, persentase aktivitas siswa sebesar 96,3%, dan persentase respon siswa sebesat 95,7%. Aspek keefektifan diperoleh berdasarkan hasil N-gain dari pre-test dan post-test yakni sebesar 0,81 dengan kategori tinggi. Hasil penelitian menunjukkan bahwa LKS sangat layak berdasarkan aspek validitas, aspek kepraktisan, dan aspek keefektifan.

The aim of this study is to develop a feasible worksheet for 7th grade Junior High School students to practice geoscience literacy. The worksheet feasibility is determined through three aspects, there are validity, practicality, and effectiveness. The worksheet mainly focused on three aspects of scientific literacy and analogy observation which uses plate tectonic boundaries as its content. Research designs used in this study are Research & Development (R&D) and One Group Pretest-Posttest Design, with quantitative descriptive analysis and data collection techniques such as observation, questionnaire, and test. The result showed that for validity aspect which determined through modus, the worksheet is valid with score 4 for didactic, 4 for construction, and 3 for technical. For practicality aspect, it is practical with modus 4 for learning implementation, 96,3% for students activity, and 95,7% for students response. For effectiveness aspect, it is effective with 0,81 for N-gain result. Based on those results, it can be concluded that the student worksheet is very feasible to be used.

Keywords: Student worksheet, geoscience literacy, analogy observation, plate tectonic boundaries.
