Efektivitas worked example dengan strategi pengelompokan siswa ditinjau dari kemampuan pemecahan masalah dan cognitive load
No full textPada penelitian ini bertujuan untuk mendeskripsikan dan membandingkan efektivitas strategi pembelajaran worked example dan problem solving dengan strategi pengelompokan siswa (kolaboratif dan individual) ditinjau dari kemampuan pemecahan masalah dan cognitive load. Penelitian ini melibatkan 64 siswa kelas 8 sebagai partisipan penelitian yang dibagi menjadi empat kelompok secara acak dengan menggunakan desain eksperimen 2 × 2 (worked example vs. problem solving) × kolaboratif vs. individual). Hasil penelitian ini mengindikasikan bahwa tidak terdapat perbedaan signifikan penerapan strategi worked example dengan pengelompokan kolaboratif dan individual ditinjau dari kemampuan pemecahan masalah. Ditinjau dari cognitive load, strategi worked example efektif ketika siswa belajar individual, namun tidak efektif ketika siswa belajar secara kolaboratif. Ketika siswa belajar secara individual, strategi worked example dapat mengaktifkan cognitive load lebih rendah daripada strategi problem solving, sedangkan ketika siswa belajar secara kolaboratif, strategi worked example dan problem solving tidak berbeda dalam mereduksi cognitive load.
The effectiveness of worked example with students\u27 grouping strategy viewed from problem-solving abilities and cognitive load
Abstract
The study aimed to describe and compare the effectiveness of learning strategies (worked example and problem-solving) with the strategy of grouping students (collaborative and individual) viewed from problem-solving abilities and cognitive load. There were 64 of 8th-grade students as study participants divided into four groups randomly using experimental design 2 × 2 (worked example vs. problem-solving × collaborative vs. individual). The results of the study indicate that there is no significant difference implementation of worked example strategy between the collaborative strategies and individuals viewed from problem-solving abilities. Viewed from the cognitive load, the worked example strategy was effective when students learn individually, but it was not effective when students learn collaboratively. When students learn individually, worked example strategies could activate cognitive load lower than problem-solving strategies, whereas when students learn collaboratively, worked example strategies and problem-solving were no different in reducing cognitive load
