Create an introduction and summary of the topic
The summary should be no more than a paragraph or two. The purpose is to provide the learner with a preview/overview and summary of the main points you presented in the weekly topic (based on the objective). The summary gives the learner another chance to learn and verify what they should be learning. The summary is a recap of the main points taught in the topic.
A good introduction is short, welcomes the learner, and introduces the learner to your topic.
