Tips for Success

Christopher Columbus High School’s C-Tech Team offers best practices for conducting successful videoconferences on topics including class (meeting) preparation, communicating effectively, and etiquette.

Class Preparation

  • C-Tech suggests that you arrive well before your videoconference starts to test the system and the interface
  • Try and minimize distracting glare and uneven lighting by pulling the shades on windows and doors and covering glass-framed wall hangings
  • Make sure the room you are in has adequate lighting. If it's too dark, the other people in your class won't be able to see you clearly
  • Make sure you have a back channel for communication - Remind (app), Instant Message (in video conference platform) or email. This allows for communication without interrupting the class session
  • Wear Columbus attire to class! Avoid plaids, stripes, polka dots, and very bright colors—they can cause distracting effects on screen

Communicate Effectively

  • Perform an audio check before the class begins to ensure that everyone can hear you
  • Talk directly into the microphone on your device. Do not turn your head from side to side while talking or your voice will fade in and out at the remote site
  • Speak in a normal voice, you shouldn't have to shout
  • When you start talking, JUST KEEP TALKING! Assume that everything is working fine. You will be interrupted if something is wrong
  • When possible, keep your microphone muted. Un-muted microphones can be the single most important problem communicating during a videoconference meeting
  • Limit excess movement to avoid looking jerky on screen


  • Platforms like Zoom allow you to load a virtual background. Some teachers may think this is fun, but most find it distracting and unprofessional
  • Look directly at the camera. This will give the teacher and fellow Explorers the impression that you are looking directly at them
  • When your microphone is on, be careful with side conversations and do not rustle papers or make tapping sounds near the microphone. Any sounds you make will be heard by the other sites and can be distractive
  • Do not cause echo. If you are causing echo, it will disrupt the videoconference
  • Be direct with your questions
  • Expect a few seconds of delay in getting an answer because of the technology and distance involved
