This document provides instructions for a lesson on digital annotation using Diigo. The lesson is intended to improve students' reading skills and last approximately one class period. Students will set up Diigo accounts, read and annotate a text by highlighting important information and adding sticky notes with questions, related knowledge, opinions, and a summary including the author's purpose. Then students will evaluate a classmate's annotations using an evaluation form before returning to improve their own annotations based on the feedback. The teacher can assess the lesson through student completion of peer evaluations or by grading individual student annotations within private accounts or collaborative class groups on Diigo.
