I particularly enjoy the idea of using both concepts.  Sometime the thought of using one standard concept becomes so focused we loose the idea that people and or student are not available at that time, such as other priorities.

Although it is or was somewhat confusing the use of technology and technology tool.  I did realize that the use of various teaching funchtions is necessary and the use of technology is very important.  It is the adjustment all instructors have to try to master, and the idea that we share some of the burden to the students is a great concept.
