Some college classes may not offer as many courses this fall if conditions change with the coronavirus pandemic. It’ll depend on whether that course can be brought online, or must be taught in person. But other fields of study require in-person contact for accreditation, or from sheer practice. Art schools are still planning to give students face-to-face time with an instructor in studio courses. Many technical programs with hands-on work also plan to do that in person. In either case, that will necessitate in-person contact during a pandemic that has infected more than 4.3 million Americans.
