Narrated lectures, when properly structured and brief, can be a good tool to deliver course content to your students.

Chunk Your Content

We recommend that you “chunk” your lectures into smaller manageable pieces no longer than 5-7 minutes. Chunking accomplishes three things for you. First, by breaking the lectures into brief topics, the likelihood of being able reuse a lecture in another course increases. Second, it is easier to update or re-record a single short video than a longer video. Third, it is easier for your students to find time to sit and concentrate for less than 10 minutes.

Write a Script

Remember to write a script for your lectures. It will help keep you from using verbal fillers and keep your videos brief, but more importantly, the script gives an alternative content piece to present to students who cannot hear your lecture and for visually impaired students. It is also very easy to create captions for your lecture by using the YouTube caption editor.

Use Images & Visual Explanations

Narrated PowerPoint lectures give you the opportunity to present your materials in a visual way, and can help you reach students who are visual learners. Try to include images that enhance your lecture. Replace text descriptions with visual representations of your topic — flow charts, graphs, diagrams, photographs, artwork, maps. Visuals will add value to your lecture and help to keep you from reading every word on your slide — something that students could easily do for themselves.
