Tech-Time : Pixels and Resolution


About Tech-Time

Tech-Time is a category on the Tech Teachers web site that consists of short videos of interest that a teacher can use to show to his/her class at the end of the day/cycle/lesson to generate discussion, inspire, create interest, inform or perhaps even help solidify some of the concepts being taught in CAT "theory".

I try find videos that I can use in my class and share them here on the web site in the category called Tech-Time. I hope you can use these videos too for your classes.

A folder with ALL featured Tech-Time videos in MP4 format is available in the Resources section

The terms “Pixel” and “Resolution” became a part of our everyday language, but not everyone knows what a pixel is and how it relates to their screen resolution. This video goes back to basics and explains how pixels work, and how many are needed to create a FullHD image.
