Commentary pages can provide:

Further information about how the readings and resources relate to the assessments that relate to the weekly objectives
Extra support around challenging concepts and context for the resources you assigned. Some folks may have more commentary pages if they use fewer course resources, while others may choose to have one commentary page. Try to keep the format as consistent as possible.

Here are a few tips to keep in mind as you create your content for this page:

Keep it interesting: Consider adding interesting stories, cases, videos, and examples into each commentary to keep students engaged. If they are hooked, they’ll look for more in future.
Add visuals: Students are more likely to stay engaged with a course if they are looking at interesting visuals instead of blocks of text.
Someone might say it better: Don’t feel like you have to take the time to develop a text-heavy commentary page each week. You may find that there are great, reliable, relevant materials already out there. Feel free to include links to videos or websites and use this page to provide context around the materials.
