<![CDATA[The low metacognitive ability of students is caused by teachers never empowering metacognitive abilities and there are still many teachers who use conventional learning approaches. The purpose of this study was to determine the effect of the SQ3R learning model on students' metacognitive abilities on ecosystem materials and to determine the differences in students' metacognitive abilities who were taught with the SQ3R learning model and conventional learning. The sample used is two classes with a total of 76 students. The research instrument consisted of a metacognitive ability test in the form of an integrated essay with learning outcomes and a metacognitive ability questionnaire which was measured using the Metacognitive Awareness Inventory Junior (MAI-Jr). The data analysis technique in this study was analyzed using ANCOVA. It was found that the influence of the SQ3R learning model on students' metacognitive abilities and the experimental class students' metacognitive abilities was better than the control class. Furthermore, there is a significant effect of the SQ3R model on students' metacognitive abilities on each indicator of metacognitive ability. So that the findings obtained can be applied by teachers in carrying out learning, especially in Biology subjects. Keywords: ecosystem, metacognitive ability, SQ3R learning model.
