I am writing my dissertation on the Universal Design for Learning in High School

I am writing my dissertation on the Universal Design for Learning in High School Math Courses and I need help writing the research design section. I have an introduction paragraph. The research questions are also written into the document. I need about two pages of research design written (double spaced, 12 pt font). I am choosing the quantitative route. Likert scale survey & Classroom observations.
