How these tools might be used
- By choosing Blackboard Collaborate, you can meet with a group of your students to discuss several topics and then end the session with a quiz.
- If you are a professor who needs to set up office hours or hold an important class session while you are away from campus, Blackboard Collaborate can meet your needs.
- Your four-person campus working group is revising a document. Rather than driving across campus and finding parking, you use Google Hangouts to set up a video call to discuss and work on the document together.
- As a pathology professor, you want to show real time video microscopy to a group of students and colleagues. The high quality video provided by WebEx Meetings Server allows you to share very detailed images in real time.
- You have to schedule a training session for regulatory personnel in all 100 North Carolina counties. Knowing that several of them cannot attend in person but can participate by phone, you decide to use WebEx Meetings Server. You can also record the session and share it with all the invitees to view at their leisure.
