I use video lectures for the preclass work assignments so there is some amount of dual coding going on. However, I have not really optimized the preclass work and have depended mostly on the retrieval practice in the iRAT and tRAT for building the knowledge base. I was wondering if anyone has best practices to share, particularly with managing cognitive load in the preclass work.
Hi @JayPascual
I have struggled for several years to get prework done.
Spontaneously, just 15-25% of students did it.
I switched to interactive videos including :
- easy questions to verify attention,
- open answer spaces to introduce their own questions along the video
activating “prevent skipping” function in order to assure they watch the whole video
Regarding cognitive load, in my experience it has to be low-medium: video length is maximum 30 mn, otherwise students get angry.
I think this prework has to introduce main concepts, and we wil later reinforce them during the exercises.
In my opinion, Edpuzzle is a great tool to create educational videos and learning analytics eases teachers´ work.
Hi @JayPascual You can refer to our blog post on managing cognitive load:
3 Best Practices to Reduce Cognitive Load during the Readiness Assurance Process
@znoel Are there any particular best practices or strategies that you would recommend?
Will try EdPuzzle @david.prandi . I think it is a great idea. Thanks for sharing!
The suggestions by @JayPascual are excellent examples of ways to manage cognitive load. Some easy ways to help manage cognitive load:
- Segmentation (break content up into smaller, more consumable segments )
- Signaling (highlight/signal key points that you want students to take from the pre-class content. Alternatively, provide them with a list of learning questions to help guide their focus & attention)
- If you’re using pre-recorded lectures with PowerPoint, there are a host of cognitive load principles that can be applied. Here’s an infographic of some common ones. [Processing: Principles of Multimedia Learning_Infographic.jpg…]
The other often forgotten piece of this is how much time you build for students to spend on the pre-class content. In other words, cognitive load is contingent upon time constraints and the finite capacity of working memory. Allowing more time/space to spend on pre-class content eases the cognitive burden. So what is “optimal” or “ideal” for pre-class work is at least partially dependent on how much time you build into your course for students to complete pre-class work.
