We don't buy into the idea that there's a "right" way to teach. We want your way, because that way is perfect for someone. But, if you're looking for some tips on how to write a great explanation, here are some best practice techniques:
Don't assume
Great explanations are the ones that meet the students at their level. It can be hard to know what that level is, but remember that your reader is someone who needs help understanding the topic. Try to not assume too much preexisting knowledge – you can always include links to more advanced applications.
Use examples
It can be hard to understand a new topic when everything is abstract. Make the topic concrete by showing an example or demonstrating an application.
Include visuals
Media like images and videos can be great teaching tools because they allow learners to process information in more than one way. Visuals work best when they're relevant to the topic and paired with explanatory text.
Ask questions
Questions help engage learners and let them check to see if they're following along. They're also a great way for you to provide interactive feedback. Is there a common misconception? Try providing that as an answer option and write feedback explaining why that isn't right.
Break it up
Explanations that are endless blocks of text can be overwhelming and intimidating. Break it up with paragraph breaks and pause points to help your readers stay focused. If your explanation is particularly long, it becomes even more important to orient your readers.
Be yourself
You might not be allowed to use personal pronouns in your English papers, but they're totally fine on expii! The best explanations are ones that are friendly and approachable – think about what your explanation would be if a friend asked you for help.
