In Moodle, a lesson is an activity that's structured to adapt answers to questions and send learners to different pages of the lesson based on their answers. Moodle adapts to the learner so content can be interesting and ever-changing. Lessons are most useful (and fun) when you're presenting branched or guided content or an assessment activity because these types of lessons enable learners to follow their own paths through the information.
Unlike other activities in Moodle, creating lessons is more complicated, but if you spend time planning them, you will quickly find they aren't as tricky as they may first appear. Taking extra time thinking and organizing your content will benefit the lesson's success and usefulness. Go on; jump in and have fun!
