Moodle is a web-based learning management system that allows teachers to create online courses, lessons, assignments, quizzes and more. Teachers can upload materials, create forums for discussions, collect and grade student work, and communicate with students in a controlled online environment. The guide explains how to access Moodle through the school district homepage, set privacy settings while building a course, and use various modules like resources, assignments, forums and quizzes to develop engaging online content and activities for students. Contact information is provided for technology support staff to assist teachers with any Moodle questions.
