Proposed policy for the office hours for academic support

How should academic support at an online university be given? A student may require a voice answer to an academic question. At an online university, most staff keep office hours which are 9am to 4pm, but academic support should be available when the student needs it. Most students at an online university are studying part-time and do their work after hours, so voice support should be available after hours if that is what is needed.

I propose that academic support at a fully online university should be available up until 9pm Monday to Friday. I propose that all students provide their mobile numbers when they ask for academic support, and the lecturer is then able to negotiate a time with them when the students can receive that support via a voice call.
