There are many distance learning technologies available to support your teaching. This section of the website provides an overview of the technologies for which faculty/staff support is available from either the College of Food, Agricultural and Environmental Sciences, Communication and Technology or Office of Information Technology at The Ohio State University. The table highlights each technology, basic characteristics, and contact information for assistance and support.
