I need your opinion on a course "teaser"
Hi friends! Say you have a web page on which you describe a course that professionals can take for continuing education credit. In the course description, you want to tease some of the content in a way that makes people think - "I want to learn that. I want to take that course."
Do you think it's better to:
a) Embed a short narrated video screencast of the course in action ... kind of a commercial that shows some of the compelling content and some cool interactivity....
b) Embed a thumbnail of the course, which launches an excerpt/demo of the course itself, so that people can experience a bit of the content firsthand. (And on any screen in the demo there would be a visible-but-not-obnoxious button that they could click to enroll in the full course whenever they're ready.)
