Research Simulation Topic

For some reason, for as long as I can remember, I have always had a difficult time narrowing my focus of topics.  As I read the text this week, I knew my topic was too broad, and it needed narrowed!  I knew I wanted to focus on the positive effects of play. Therefore, after much consideration, I have decided to narrow the focus of my topic, and thus, I want to research the role of play in aiding socio-emotional development in Pre-School aged children.  I feel very passionate about this topic, and I feel that learning more about play in relation to socio-emotional development will aid me as I advocate.  Just this week, I had a meeting with my supervisor and principal, both of whom are in defense of play, and are open to learning more about the positives of it (my supervisor was adamant about making sure we are getting in the substantial portion of the day in relation to play).  Researching this will also give me resources to give to families and others who may question why we have play for substantial portion of the day.  

 In the coming days, I know that I will need to decide if I plan to use an inductive or deductive method for gathering information.  Do any of you have any suggestions regarding this?  I know from your posts last week that some of you have research experience.  Any tips would be appreciated!

Also, do you have any research articles or information that you would be willing to share about play?  I look forward to hearing from you!

Thanks!
