I am designing a questionnaire for algebra 2 students. I would like to conduct interviews so that I may determine the initial conceptual understanding that my students possess before instruction. I would like for the questions to be broad in order to leave the door wide open for responses. Some examples that I have started with: #1. What is algebra? #2. What are variables used for? #3. What is a function? I would appreciate any suggestions. I would like to have 8 to 10 questions!
