<![CDATA[Penelitian ini bertujuan untuk mengetahui efektivitas model pembelajaran inquiry terintegrasi laboratorium virtual terhadap pemahaman konsep dan keterampilan metakognitif siswa. Quasi eksperimen dengan nonequivalent control group design digunakan dalam penelitian ini. Sampel penelitian ini adalah 56 siswa yang terbagi ke dalam 2 (dua) kelas parallel yang dipilih menggunakan cluster random sampling technique. Instrumen yang digunakan berupa tes pemahaman konsep dan instrumen lembar penilaian (LP) keterampilan metakognitif yangtelah dinyatakan valid dan reliabel. Data penelitian dianalisis secara deskriptif menggunakan persamaan n-gain dan statistic dengan bantuan software IBM SPSS 23 Version. Hasil penelitian menunjukkan bahwa pemahaman konsep siswa pada kelompok eksperimen (mean= 79,19; n-gain= 0,76 dengan kategori tinggi) lebih baik dari kelompok kontrol (mean= 43,08; n-gain= 0,36 dengan kategori sedang) dan berbeda secara signifikan (p < 0.05). Keterampilan metakognitif siswa menunjukkan hal serupa, kelompok eksperimen (pertemuan I= 54,69 (pertemuan II= 67,86; pertemuan III= 79,24) ditemukan lebih baik dari kelompok control (pertemuan I= 46,09; pertemuan II= 53,01; dan pertemuan III= 55,13). Hasil penelitian menunjukkan model pembelajaran inquiry terbimbing terintegrasi laboratorium virtual efektif dalam meningkatkan pemahaman konsep dan keterampilan metakognitif siswa dalam pembelajaran kimia materi larutan penyangga. Virtual Laboratory Integrated Guided Inquiry Learning Model to Improve Students' Concept Understanding and Metacognitive Skills Abstract This study aims to determine the effectiveness of the virtual laboratory integrated guided-inquiry learning model on students' concept understanding and metacognitive skills. Quasi experimental with nonequivalent control group design was used in this study. The sample of this study was 56 students who were divided into 2 (two) parallel classes which were selected using the cluster random sampling technique. The instruments used were in the form of a concept understanding test and a metacognitive skill assessment sheet (LP) which had been declared valid and reliable. The research data were analyzed descriptively using the n-gain equation and statisticaly with the help of IBM SPSS 23 Version software. The results showed that students' concept understanding in the experimental group (mean = 79.19; n-gain = 0.76 in the high category) was better than the control group (mean = 43.08; n-gain = 0.36 in the medium category) and significantly different (p < 0.05). Students’ Metacognitive skills showed the same thing, the experimental group (meeting I = 54.69; meeting II = 67.86; meeting III = 79.24) was found to be better than the control group (meeting I = 46.09; meeting II = 53, 01, and meeting III = 55.13). The results showed that the virtual laboratory integrated guided-inquiry learning model was effective in improving students’ concept understanding and metacognitive skills in buffer solution chemistry learning subject.]]>
