IOWA CITY, Iowa (AP) — A large community college system in eastern Iowa says that most, but not all, of its classes will be temporary held online to try to slow the spread of the coronavirus. Kirkwood College said that all classes with a lecture format will not meet in person beginning March 23 through at least April 10.The college is based in Cedar Rapids but has a secondary campus in Iowa City and several centers throughout the region. Its announcement comes one day after Iowa’s three public universities said they would suspend in-person instruction through at least April 3.
