To give operational definitions to the hypothetical constructs of handedness and learning development, I would define handedness as a strong preference for either the left or right hand, as exhibited through a child's daily activities, such as writing or eating. For learning development, I would focus on test scores on standardized tests such as the MontCAS, which screens for understanding of reading/math.
I would use a cross-sectional research design with participants' ages ranging from 5-10 in order to study learning development at different stages in their education. I would select 25 left and 25 right handed kids from each age group. I would utilize Teacher/Parental reports for additional information on a child's learning patterns/abilities, in addition to the data that could be gleaned from test scores.
