If your lectures are essentially a summary of the text, students will figure that out and probably choose to either read or watch your videos. Consider the use of reading guides with questions the students answer while reading to ensure they get the main points. Actually, it can also be helpful to encourage students to take notes on instructional videos as well.
It is also acceptable to link to materials you've found online rather than create everything yourself. The role of an instructor in the digital age has moved more to someone who has the expertise to curate online information. You will be able to get your perspective in the course through introduction videos, feedback, news items, and the creation of content you cannot find online.
Here are some suggestions on when to create instructional videos:
- To fill gaps in available content - If you are able
to find online materials that meet your teaching objectives, use them.
Creating high quality multimedia content is very time consuming. If you
can't find what you need, then create something yourself.
- To make connections between materials - It's ideal
if you can set up low stakes assessments such as discussions where the
students can make connections themselves, but sometimes they still need
you to make the connections.
- To clarify the materials or elaborate on difficult concepts
- If you've taught the class before, you know where the students
struggle and will need extra help. Sometimes they need to hear the same
information in a few different ways, but save your effort for when it's
really necessary. Consider using videos created for this purpose in your
face-to-face class as well, so they can review.
- To emphasize very important concepts - There are
probably some concepts in your class that are so important that you
really want to emphasize them - those are the things that could be
digital content. Don't spend a lot of time creating a video about
something that isn't particularly important in your course.
- To add your own stories and personal experience related to the content. People learn particularly well from stories but adding too much extraneous information can inhibit learning of the core content.
- To introduce modules - Creating an intro video can
personalize you to the students and allow you to share your enthusiasm,
although you may not actually be sharing much content.
- When it can be reused - Try to create videos of concepts that don't change regularly so you can use them for a long time.
- If you use an example, use a generic one rather than a very
time-specific one. You can also include a time-specific example in a
medium like text that can be changed more easily.
- Don't specifically reference the time of year, or the class you're
creating it for. You may be able to use your videos in multiple classes -
maybe as a review for a more advanced class.
- Don't talk too much about the book, in case it changes.
- Try not to reference assignments or discussions because you may decide to change them later, unless you are creating an introduction video you anticipate changing for each class.
- If you use an example, use a generic one rather than a very time-specific one. You can also include a time-specific example in a medium like text that can be changed more easily.
