"There has evolved from the research conducted by cognitive and behavioral psychologists a set of very specific, empirically validated procedures for teaching concepts. If followed, these procedures provide far more efficient and effective concept instruction than that typically seen in classrooms or mediated instructional materials.
"The procedures outlined in this book may appear to be extremel laborious compared to procedures you are now using to prepare instructional materials. However, after you have prepared several lessons using the recommended procedures, you will find that your planning efficiency has actually increased. In addition, your students will find your lessons more enjoyable and much easier to understand.
"... Instructional design is a phrase which means selecting and arranging instructional materials in a way which helps students learn more efficiently and effectively. It also means selecting and arranging special materials which allow you as a teacher, or the students as learners, to find out whether they have learned what you intended."
Now that's pretty much how I explain things, but I found this entire passage really clear.Â I can't wait to read the rest of the book.
