Cool. Now we are where I want to be. There is (almost all) really bad
CBT. In fact, I currently know of only two examples of what I consider
good CBT.

The first, and the one on which I learned my design principles, is a
calculus course written by Jerry Uhl (U of Illinois) and Bill Davis (Ohio
State). This course is completely contained in Mathematica documents.
It uses socratic like principles and asks students to experiment by
copying mathematica code and making their own mathematica code. It is
in this way that the Mathematics is taught much the same way experimental
science is taught. The instructors do not lecture, but instead coach the
course. They also are encourged not to answer questions directly but to
attempt to lead students to their own conclusions by asking them to
consider questions.

The power of this method becomes evident when one enters the "lab" and
sees students discussing mathematics and creating their own principles
and demonstrations for hours on end. One does not generally see this
in a standard "stand up" calulus course.

The secret of this course, is embedding the materials in a program which
gives the students the SAME editorial and programming power that the
author has. This gives students a wide range of creative freedom
in the medium to ask and answer their own questions.

This is more than "interactive" it is "USERactive".

The other example is of my own design to teach HTML and JavaScript.
The course is embedded in an evironment (online editor) in which students
can experiment and create on their own as well as follow the tutorials'

To see this for yourself see

I am also making courses on other programming languages such as
PERL, C++ and Java.

Jason, good CBT can and is being done.
