Consider a short survey to assess what is working for your students and parents. Keep the survey short, maybe even offer it verbally, and if written offer multiple choice questions with one fill in the blank style summarizing question versus all fill in the blank. This makes gathering data quicker and limits those who might want to use the survey as platform.
Sometimes what works for someone else just doesn't work for you and your situation. Comparing yourself to others often leads to disappointment. As the saying goes, "Comparison is the thief of joy."
