Development of Guided Inquiry-Oriented Student Activity Sheets to Train Metacognitive Skills on the Material of Reaction Rate
Penelitian ini mengembangkan Lembar Aktivitas Peserta Didik (LAPD) berorientasi inkuiri terbimbing untuk melatihkan keterampilan metakognitif pada materi laju reaksi. Latar belakang menunjukkan rendahnya keterampilan metakognitif dan kesulitan peserta didik memahami materi tersebut. Metode yang digunakan adalah R&D model Borg and Gall hingga tahap uji coba produk, dengan subjek 30 siswa kelas XI-8 SMAN 1 Gedangan. Hasil penelitian menunjukkan bahwa LAPD yang dikembangkan valid, praktis, dan efektif. Validitas isi dan konstruk tergolong sangat valid dan valid, kepraktisan terlihat dari respons peserta didik mencapai 90,9%, dan aktivitas relevan lebih dari 91%. Efektivitas terlihat dari peningkatan skor N-Gain (0,55–0,90) dan hasil uji paired sample t-test yang signifikan (Sig. 0,000). Angket inventori metakognitif juga menunjukkan hasil sangat baik. Dengan demikian, LAPD ini layak digunakan untuk melatihkan keterampilan metakognitif dalam pembelajaran laju reaksi.
This study developed a guided inquiry-oriented student activity sheet to train metacognitive skills on reaction rate material. The background shows low metacognitive skills and students' difficulties in understanding the material. The method used was the Borg and Gall R&D model up to the product trial stage, with 30 students of grades XI-8 of Gedangan High School as subjects. The results showed that the developed student activity sheet was valid, practical, and effective. Content and construct validity were classified as very valid and valid, practicality was seen from student responses reaching 90.9%, and relevant activities were more than 91%. Effectiveness was seen from the increase in the N-Gain score (0.55–0.90) and the results of the paired sample t-test were significant (Sig. 0.000). The metacognitive inventory questionnaire also showed very good results. Thus, this activity sheet is suitable for training metacognitive skills in learning reaction rates.
