My Research Simulation Project

My simulation research project is I want to study the effects on a child and its single-parent family having a mentoring program come into his or her home and mentor the parent on how to help his or her child physically, emotionally, and academically.  The project would start before the child is born with basic parenting classes and until the child is four.  Through this time, an early childhood educator, social worker, or advocate would come once a week into the parent’s home and provide techniques and strategies for the parents to help their child grow academically, emotionally, and physically.  By the time the child is four he or she will be given an assessment to see what progress has been made and the parents will also be given survey about what he or she has learned about parenting.  The biggest factor I have learned from completing the research simulation is sometimes it takes triangulation, which is the use of multiple research methods to get full and complete data is the best way to see the full picture.  What do you see would be the best way to start collecting data of my research simulation?
