Which of the following helps improve adult learners' retention of information?

Peer teaching is particularly effective in enhancing adult learners' retention of information due to several key factors. When adults engage in peer teaching, they not only reinforce their own understanding of the material but also deepen their grasp as they prepare to teach others. This method fosters active engagement, critical thinking, and discussion, allowing learners to explore different perspectives and clarify their understanding.

Moreover, the interactive nature of peer teaching encourages collaboration and discussion among learners, creating a dynamic learning environment. When individuals explain concepts to their peers, they are more likely to retain the information as they process and articulate it in their own words. This social aspect of learning is crucial for adult learners, who often benefit from connecting new knowledge to their existing experiences and frameworks.

In contrast, independent study may limit interaction and discussion; while it can promote self-discipline and individual learning, it may not suffice for retention compared to peer interactions. Group projects can promote collaboration but may vary in effectiveness depending on the group's dynamics and individual participation. Lecture-based sessions typically focus on information delivery rather than interactive learning, which may not engage adult learners as effectively, ultimately impacting retention.
