Our professors always mention how difficult it is to 'connect' with students when teaching distance learning. It feels more natural to talk to students casually before and after class, or meet them in the office. I've been really impressed with 2 tools from Adobe that help make this 'connection' easier for professors in our program.
One is the Adobe Commenting on PDF files. Most people know that you can type comments, but did you know you can also record your voice with commenting? It's easy to use, and most professors have access to it with Adobe Acrobat's full version. Our students say they love hearing their professors' voices with feedback.
The other tool is Adobe Connect. This product allows you to have web meetings and collaborate with up to 5 people in their 30 day free version. Professors can use a webcam and microphone to meet with teams, or give individuals some extra tutoring. They could even use it for a remote guest speaker! It's pretty easy to use, and includes the ability to have a whiteboard, share a file, or show your desktop and record. Thunderbird purchased a license to make it even easier for faculty.
