Development of Integrated Curriculum Student Worksheet to Train Student Scientific Literacy Skills in Reaction Rate Material

Penelitian ini bertujuan untuk mendeskripsikan kelayakan LKS kurikulum terpadu untuk melatih keterampilan literasi sains siswa pada materi laju reaksi ditinjau dari kriteria validitas, praktis, dan keefektifan. Penelitian ini menggunakan metode Research and Development (R&D) hingga terbatas pada tahap uji coba. Instrumen yang digunakan adalah review dan validasi, observasi kegiatan, angket siswa, dan lembar tes keterampilan literasi sains. LKS yang dikembangkan diujikan pada 13 siswa kelas XI SMA Negeri 1 Grati Pasuruan yang sudah menerima materi laju reaksi. Validitas LKS diperoleh berdasarkan penilaian dari dua dosen kimia Universitas Negeri Surabaya dan dua guru kimia SMA Negeri 1 Grati diperoleh prosentase 91,46% untuk konstruk dan 88,96% untuk validitas isi. keduanya dalam kategori sangat valid. Praktik LKS diperoleh berdasarkan respon siswa dan observasi aktivitas yang mendapatkan respon positif sebesar 98,82% dan hasil aktivitas siswa relevan sebesar 98,83% baik dengan kategori praktik sangat valid. Keefektifan LKS diperoleh berdasarkan hasil tes keterampilan literasi sains siswa dimana siswa dinyatakan tuntas dengan rentang  nilai  83,9-96,8  dan  nilai  N-gain  0,8  dengan  kriteria  tinggi.  Masing-masing   ranah keterampilan literasi sains meliputi konteks sains, pengetahuan sains, kompetensi sains, dan sikap terhadap sains mendapat persentase secara berurutan 90%, 91%, 91%, dan 96%.

This research aims to describe the feasibility of integrated curriculum student worksheet to train student scientific literacy skills in reaction rate material assessed from validity, practical, and effectiveness criteria. This research uses Research and Development (R&D) method until limited the trial stage. The instruments are the review and validation, activities observation, student questionnaire, and science literacy skill test sheets. The developed student worksheet was tested on 13 students of XI grade at State Senior High School of 1 Grati Pasuruan that already accept reaction rate material. The validity of student worksheet is obtained based on assessment from two chemistry lecturers of Universitas Negeri Surabaya and two chemistry teachers of State Senior High School of 1 Grati and obtained a percentage are 91,46% for construct and 88,96% for content validity with both in very valid category. The practical of student worksheet is obtained based on student response and activities observation who get positive response of 98,82% and relevant student activities result of 98,83% both with very valid practical category. The effectiveness of student worksheet is obtained based on test result of student science literacy skills where student declared as complete with value range 83,9-96,8 and N-gain value of 0,8 with high criteria. Each domain of scientific literacy skills include science context, science knowledge, science competencies, and attitude towards science got percentages sequestially 90%, 91%, 91%, dan 96%.
