Peer tutoring involves pairing students, usually with a higher-level student helping a lower-level student. This helps deepen understanding as students discuss concepts and use scaffolding techniques. Peer tutoring increases engagement and helps students progress in their zone of proximal development. It benefits skills in literacy, reading comprehension, and subject areas like algebra. Positives are that students learn from each other, enhance their skills, and take control of their learning. Negatives can include lack of focus or progress between students. Sources discussed show peer tutoring shifts teacher and student roles, and enhances student motivation through interaction.
