Pricing for learners/attendees is another matter. Sometimes one drives the other, sometimes they don’t (it depends on the association’s education mission and strategy).

I definitely agree with your two points. During my time working for a content creation vendor, I saw a single five-hour seat time course plummet from mid-six figures to upper five figures. We developed moderately interactive courseware — no high end simulations, but plenty of strong on-screen interactions, some branching, etc. All because of the tools available — more templates, more WYSIWYG, ASP, XML, and other developments in technology made the difference.

Would you attribute the drop in prices to the same reasons?

As a vendor of content creation tools, we notice that price depends mainly on
the product quality and on the target market.
And the trends for elearning content development now are
1. Price for high-quality content goes up.
2. Price for low-quality content goes down. It used to be expensive.
