Abstrak Telah dilakukan penelitian yang bertujuan mendeskripsikan kelayakan LKS secara teoritis. Penelitian ini menggunakan model pengembangan 4-D namun hanya sampai tahap develop. Data yang diperoleh dianalisis secara deskriptif. Kelayakan teoritis LKS ditentukan berdasarkan hasil telaah LKS. Hasil penelitian menunjukkan bahwa LKS 1 dan LKS 2 yang dikembangkan dinyatakan layak secara teoritis berdasarkan kriteria isi, penyajian dan kebahasaan. Kriteria isi, penyajian serta kebahasaan LKS 1 memperoleh rata-rata skor berturut-turut 3,58; 3,75; dan 3,83. Kriteria isi, penyajian serta kebahasaan LKS 2 memperoleh rata-rata skor berturut-turut 3,69; 3,58; dan 4.

The theoretical feasibility of the student worksheets was determined based on the result of validation. The results show that the student worksheet 1 and student worksheet 2 developed are theoretically feasible based on the criteria of content, presentation and language. In details, the criteria of content, presentation and language of student worksheet 1 get the average scores of 3,58; 3,75; and 3,83. The criteria of content, presentation and language of student worksheet 2 obtain an average score of 3,69; 3,58; and 4.
