2021 #VWEDU: DTA: Could a college replace lecturers with videos? A good lecture video could serve the entire freshman class. And all the online classes, too

Could a college replace lecturers with videos?  

A good lecture video could serve the entire freshman class.  

And all the online classes, too

Suppose videos replace lectures in college.

College lectures online

• Collège lecturers can convert to online teaching: Here is how:
• Model for many freshman "lecture" classes. Teaching online. Reinventing the teacher career. Teaching is creating conditions in which students learn.
• But suppose they don't.  Could a college do that instead?
• No point in simply converting all the lectures.. Just convert the best lectures.

What are the best lectures?

• Those that best meet the student needs.
• Two measures go into that:  Student performance and student satisfaction.
• Since student study preferences vary, there is probably no single best lecture.
• But If multiple lectures are available on the same subject matter, there is a procedure for evaluating them on the criteria above.
• Thus a college could develop an evaluated set of lectures that should be better than the work of any individual professor. 
• It could even offer lectures for specific learning styles.

The value of videos (for research)

• A video is replicable. A live lecture is not.
• The video of the lecture by professor X is the same every time.
• Live lectures will vary on each occasion.
• If we evaluate the video,  we can be sure that it stays the same.
• And that it stays the same in the future.  

The value of videos (as educational products)

• The evaluation results are much more valuable for the video than they would be for the live lecture for professor X.
• The video can be replicated without limit.  
• The copyright owner can sell licenses to other schools.
• Professor X could make a lot of money from that if he owns the copyright.  
• If the school pays for making the video, the school may own the copyright.

Video collections as textbooks

• Of course.  They are as easy to duplicate as textbooks are.
• They might even be combined with textbooks.

What happens to lecturers?

• A few make a lot of money making video lecturers.
• Most transfer to other work, either in the schools or elsewhere.

How do schools justify their charges for such courses?

• They don't.  Universities augment the courses with DTA's. 
• The Digital Teaching Assistant (DTA) for MUVES (virtual worlds): Summary with JIT learning design
• Junior colleges merely offer them online at low cost.
• Smart high school students take them online at their school or at home.
• Many 4-year colleges simply allow transfer of credit from junior colleges, perhaps with certification tests.
