Since ECHIP no longer exists, I guess it is OK to reveal some of the stuff we did. We taught a course to engineers for more than 20 years and our statistics indicated that 9 out of every 10 attendees ran at least one experiment after the course.

One of the things that was done was intended to break the mind set of the students, and we did this by posing a problem for them to solve before we attempted to teach them anything. We usually used the funnel, although in the early days it was a computer simulation. Many students had some idea of design to begin with, and tried to put what they knew to work with mixed success, while others rolled their own. Teams were used, and someone from each team reported the results. Criticism was always constructive. We followed this up by solving the problem using a design, and we explained the methodology as we went along with all students collecting and analyzing the data on their own computers.

Almost all students (even those reluctantly required to attend by management) bought into the problem; becoming so interested, that we often had to chase them from the classroom at the end of the day.
