Beefing up the bibliography

After talking with Dr. Dawson last week, I decided to refocus and beef up the bibliography that we had to turn in last week. The reason I am doing this is to hopefully get an article published about the use of virtual learning environments in engineering education. I did a literature search today and found 20 articles that initially match the search criteria. I will have to read them over to see if they all pertain to what I want to write about, and if not, I will exclude them.
