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.

- 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.
- Educational presentations in 3D. In the old days, we called them "lectures". But with modern technology, we don't just stand there and talk.
- A different kind of lecture. Dickens and the London of his time. You can have a lecture without an auditorium. You can even do without slides.
- Early Cretaceous Meat Eating Dinosaurs by Dr. Bill Schmachtenberg & Dr. Alex Hastings. Lecture and discussion in a virtual world.
- How to present without an auditorium. Present in a simulation of the subject. Valerie Hill tells about Research Row in the digital Dickens Project (excerpts).
- Can virtual worlds support large lecture classes? The past is not the future
- You could give live lectures on a virtual campus. But why would you?
- Era of the entrepreneurial educator. The unbundling of education opens the gate for entrepreneurs.
- The coming of the virtual campus: Online schools need an online campus. "Stanford University Students Flock to a Virtual Campus"
- Once you hear lecture about swimming, you never forget what you learned about lectures. Talking is not teaching.
