If you want to limit your searching specifically to dissertations from your program, go to Scholar Commons, which is USC's institutional repository. To find Scholar Commons in our list of databases you can: 

• change "All Database Types" to Dissertations and Theses,
• search for it by name, or
• click on the letter S

Once you are in Scholar Commons, start with this search:
            “doctor of education”
AND    “curriculum and instruction”

(The first graduates from your program were in 2017, so 01/01/2017 was added as the beginning search date.)

If you would like to limit your search even further, look on the right side of the results screen and you'll see a tab for "Show Search." Click “Show Search” and then you can adjust this search by adding another search box (look for the green + icon) and additional search terms.
