Description

Course Description Icon

This lesson will do a quick dive into the evolution of desktop monitors.

The earliest computers were rooms filled with electronics-filled cabinets — usually with little or no visual indication of the information they were processing and spitting out.

For that, you needed a paper print-out. It took until the early 1970s for cathode-ray tube (CRT) technology, already widely used as the core of television sets.

Eventually the LCD takes center stage

Target Audience

We think this material can be understand by students as young as 3rd grade.

Testing?

YES.  Just like most of our micro-lessons there will be a test after this lesson.

The entire class is 20 minutes long. 15 minutes will be devoted to material mixed with tests and games.

The remaining 5 minutes for testing or retesting. You will do great. Don't worry. You can always retest again if you aren't able to achieve 80% or better the first time around.
