Cornell note taking is a system for organizing class notes that involves dividing a page into three sections - a narrow column on the left for questions and key terms, a wider column on the right for notes, and a summary section at the bottom. The presentation provides instruction on how to use the Cornell note taking system, including taking notes during class, adding questions to the left column after class, and writing a summary of the lesson. Benefits of the Cornell method include organizing information for easier studying and review.
