How are you Yukiko Oki,
I believe majority of colleges and universities might still be closed at this point because of the virus---ours shutdown back in March. The most recent report indicated public schools can re-open again this fall---September in my district. With that said, you may have to wait till then---relative to this assignment.
For colleges and universities, the wait might be shorter than K-12---the semester enrollment may have already started and back to normal operation. Your chance of getting this assignment done is much higher in California-the state is a filter ground for ESL teachers with Japanese students. Perhaps, even the public school educators in your state of Hawaii could help complete your survey. I don't personally know teachers who are teaching online-who can help complete your survey, but the probability is high if you could wait when all schools will open up again this fall---teachers who are teaching online are asked to follow the college or university academic calendar year. But those instructions, too, had already ended last month in June---if not sooner. Congratulations for getting your advance degree done. Enjoy summer!
