I’ve had two high school biology teachers and two university professors tell me that they do not want to post observations on iNaturalist because they worry about getting the identifications wrong and the students questioning their abilities. Since I don’t know their classrooms, I have to respect that. But I still encourage them to get an account and make at least 100 observations under a pseudonym before designing lesson plans and class activities. We also have faculty who are very successful using iNat themselves and with their students.
