Vyew allows you to meet and share content in real-time or anytime. Upload images, files, documents and videos into a room. Up to 10 users can access and contribute at anytime. FREE!
Some teachers are using Vyew to conduct web-based presentation/lectures, hold office hours, as well as hold synchronous online instruction outside of the regular school day.
Some teachers are using Vyew to enhance a blended (F2F and online) learning experience through Blackboard (Connected Classroom) for their students. If you are interested in building an online course for your students in Blackboard, please click on the Request support link below.
