A substantive topic of interest is the importance of a diverse teaching workforce as there are disparities between the racial composition of American children and the racial composition of the American teaching force. The three core designs discussed with mixed methods research were 1. convergent, 2. explanatory sequential and 3. exploratory sequential. Directions: There are validity issues attached to each type of mixed methods design. Choose one of the core designs you might use in a study for the substantive topic of interest above (the importance of a diverse teaching workforce as there are disparities between the racial composition of American children and the racial composition of the American teaching force) and explain in a paragraph that indicates what specific strategies you would use to address the potential threats to validity for this design
