Brief overview and history of instructional technology

I really liked this article by Robert Whelan, "Instructional Technology & Theory
A Look at Past, Present & Future Trends." It gave a brief summary of the three major learning styles: behaviorism, cognitivism, and constructivism, which was a good review for me. I agreed with what he said regarding new infrastructures: “These emerging infrastructures are, however, useless without content, and trends in content development are characterized by the most interesting innovations.” This is what my library is grappling with, as we determine where and how our electronic services should be delivered.
