Pengembangan LAPD Berorientasi Contextual Teaching and Learning (CTL) untuk Melatihkan Literasi Sains pada Materi Kesetimbangan Kimia

The Development of Contextual Teaching & Learning-Oriented Worksheet to Improve Science Literacy on Chemistry Equilibrium Materials

Tuntutan keterampilan abad 21 sejalan dengan tujuan Kurikulum Merdeka, salah satunya yaitu untuk menumbuhkan kemampuan menganalisis berbagai isu ilmiah dan mengevaluasi berbagai fenomena dalam kehidupan sehari-hari  Penelitian ini bertujuan untuk menghasilkan Lembar Aktivitas Peserta Didik (LAPD) berorientasi Contextual Teaching and Learning (CTL) yang dapat meningkatkan kemampuan literasi sains pada materi kesetimbangan kimia. Metode yang digunakan pada penelitian ini mengacu pada model pengembangan Borg and Gall dengan 3 tahap, yaitu tahap studi pendahuluan, tahap pengembangan, dan tahap uji coba. Desain penelitian ini menggunakan One Group Pretest Posttest. Kelayakan LAPD terkait aspek validitas diukur berdasarkan hasil penilaian 3 validator, aspek kepraktisan ditinjau dari hasil angket respon dan pengamatan aktivitas siswa, sedangkan aspek keefektifan dilihat dari nilai N-gain pretest-posttest literasi sains. Hasil dari penelitian ini menunjukkan bahwa validitas isi sebesar 87,88% dan validitas konstruk 90,79% dengan kategori sangat valid, nilai kepraktisan 96,1% respon positif peserta didik dan 94,43% berdasarkan aktivitas siswa, serta rata-rata N-gain sebesar 0,7853 pada kategori tinggi. Kesimpulan yang diperoleh, LAPD berorientasi CTL valid, praktis, dan efektif untuk meningkatkan literasi sains siswa pada materi kesetimbangan kimia.

The challenges of 21st century skills are in line with the objectives of the Merdeka Curriculum, one of which is to grow the ability to analyze various scientific issues and evaluate various phenomena in everyday life. This study aims to produce Contextual Teaching and Learning-oriented student worksheets that can improve science literacy skills on chemical equilibrium material. The method used in this research refers to the Borg and Gall development model with 3 stages, namely the preliminary study stage, the development stage, and the trial stage. This research design uses One Group Pretest Posttest. The feasibility of the student worksheet related to the validity aspect is measured based on the results of the assessment of 3 validators, the practicality aspect is reviewed from the results of the response questionnaire and observation of student activities, while the effectiveness aspect is seen from the N-gain value of the pretest-posttest of science literacy. The results of this study showed that the content validity was 87.88% and construct validity was 90.79% with a very valid category, the practicality value was 96.1% positive response and 94.43% based on student activity, and the average N-gain was 0.7853 in the high category. In conclusion, the Contextual Teaching and Learning-oriented student worksheets is valid, practical, and effective to improve students' science literacy on chemical equilibrium material.
