Hi, Georgia! I am currently working on my dissertation in special education. (My topic involves Asperger's.) You are correct about the Ed.D. = practical and Ph.D. = theoretical.
The big question is "What do you want to do with your career after you finish your doctorate?" If you are hoping to teach on the college level and continue researching, you would be better served by a Ph.D. People with Ed.D.s tend to become administrators such as principals, deans, and department heads. I think the Ed.D. would lead to a career that involved more social skills.
As far as the actual research, and without getting into a quagmire of doctoral info, there are research methods that can accommodate a variety of social needs and preferences. For example, I can tell you a bit about my own topic. I am using a design known as Interpretative Phenomenological Analysis (IPA). One of the main "rules" of IPA is to treat the participants (in my case, people with Asperger's) as the experts. The participants become co-researchers and are offered the opportunity to check my work for accuracy. I am using online interviews through the private messaging feature here at WrongPlanet. The people who have been kind enough to share with me are not subjected to face-to-face interviews, telephone interviews, or instant messaging interviews. I chose this method of interviewing in hopes of making the experience as comfortable as possible for my participants. (Of course, if a participant prefers telephone communication, I would be willing to accommodate that preference.)
If you have any other questions, or just want to talk doctoral studies in special education, feel free to PM me.
