Development of Problem Based Learning (PBL) Oriented E-LAPD to Improve Students' Chemical Literacy Skills on Acid-Base Material

Penelitian ini bertujuan untuk mengetahui kelayakan E-LAPD berorientasi Problem Based Learning (PBL) untuk meningkatkan kemampuan literasi kimia peserta didik pada materi asam basa. Kelayakan E-LAPD berorientasi Problem Based Learning (PBL) yang dikembangkan ditinjau berdasarkan aspek validitas, kepraktisan, dan keefektifan. Jenis penelitian ini menggunakan Research and Development (R&D) dengan model pengembangan 4D. Model penelitian ini terdiri dari tahap define, design, dan dibatasi hingga tahap develop. Desain uji coba pada penelitian ini menggunakan one group pretest-posttest design. Validitas E-LAPD menunjukkan bahwa E-LAPD 1 dan 2 pada kriteria isi mendapatkan modus 4 dengan kriteria valid. Pada kriteria konstruk, E-LAPD 1 dan 2 mendapatkan modus sebesar 4 dengan kriteria valid. Kepraktisan E-LAPD ditinjau dari respon peserta didik dan didukung oleh hasil observasi aktivitas peserta didik yang mendapatkan persentase sebesar 92,69% dan 91,67% dengan kriteria sangat praktis. Keefektifan E-LAPD mendapat kriteria sangat efektif ditinjau dari N-Gain Score literasi kimia sebesar 0,63 dengan kriteria sedang. Keefektifan E-LAPD juga didukung oleh hasil tes kognitif peserta didik dengan ketuntasan klasikal mencapai 86,11%.

This study aims to determine the feasibility of Problem Based Learning (PBL) oriented E-LAPD to improve students' chemical literacy skills on acid-base material. The feasibility of E-LAPD oriented to Problem Based Learning (PBL) developed is reviewed based on aspects of validity, practicality, and effectiveness. This type of research uses Research and Development (R&D) with the 4D development model. This research model consists of define, design, and limited to develop stages. The trial design in this study used a one group pretest-posttest design. The validity of E-LAPD shows that E-LAPD 1 and 2 on content criteria get mode 4 with valid criteria. On construct criteria, E-LAPD 1 and 2 get a mode of 4 with valid criteria. The practicality of E-LAPD is reviewed from the students' responses and supported by the results of observations of students' activities which get a percentage of 92.69% and 91.67% with very practical criteria. The effectiveness of E-LAPD received very effective criteria in terms of the N-Gain Score of chemical literacy of 0.63 with moderate criteria. The effectiveness of ELAPD is also supported by the results of students' cognitive tests with classical completeness reaching 86.11%.
