Hi. Just viewed Dr. Merrell's video and thought it was informative, insightful and helpful. I was just thinking yesterday about the numerous amount of information available on instructional design and trying to determine what I should focus on or skip. Dr. Merrell talks about this. Just wanted to share it with my classmates and anyone who's interested in viewing. See link below.
Hope its helpful. Thank you.
