From 1987 to 1997 I researched and wrote my dissertation on "Task Enjoyment and Mathematical Achievement." Part of the reason it took so long was that I changed my focus from creativity to intrinsic motivation. (In those days at the University of Chicago there were few faculty who wanted to study creativity.) Another reason was that I collected classroom observations and findings for four years. This explains why there are multiple studies in the dissertation.
After graduating, my career took another turn and I did not pursue further research or publication. However, I continue to apply the findings of the importance of flow and task enjoyment in what I have done as a program director, eLearning architect, innovation consultant, business owner and professional musician.
If you are interested in this topic, I am making my dissertation available. Feel free to download it and use it as you wish. I merely ask that you cite the information you use.
