Teaching Online: Continuity Guide-Web Conferencing Tools

ACC has four web conferencing tools available for students and employees that are compatible with online instruction: Blackboard Collaborate, Google Meet, Zoom, and Webex. We recommend faculty use the tool that they are most comfortable with for their teaching. To decide which web conferencing tool is best for your needs or to choose a new one, please reference the table below.

Note: Webex requires account requests and setup, so our staff will only be providing support to those that already have their accounts up and running.

Web Conferencing Tools

Review the chart below to choose which technology might be right for your teaching needs.

Note: To use these web conferencing tools, faculty need a computer with the web conferencing tool installed, an internet connection, a microphone, and a webcam (can be built into laptop). Faculty in need of equipment, please visit the Check Out Equipment page for options.

To use these web conferencing tools, students can connect via computer/laptop, on mobile apps for the web conferencing tool, or call in via phone. If students are in need of equipment, please direct them to visit the “Technology Support” section on the ACC Remote Student Support page.
