Summary of Project:
It can be difficult for students to understand how a computer monitor works, and even more so to understand how an individual pixel works. When telling students that Red, Green, and Blue can be combined to make white, students often have a large disconnect. It doesn’t make sense, at first, that shrinking individual Red, Green, and Blue colors into a tiny space will produce the color white, especially when we’ve been taught since we were really young that they (Well, actually, Red, Yellow, and Blue) produce black (or a really ugly brown). The following image shows how difficult it is to wrap our heads around this RGB idea:
Because of this, I developed a software program (in Java) which allows students to see how the individual colors of Red Green and Blue (RGB) can be combined and pressed into such a small area that they appear to be a single color.
It’s amazing, when watching the RGB colors get smaller and smaller, that you can actually see the change in color take place. It’s even more apparent when you begin adjusting the Red, Green, and Blue sliders to create different colors.
This program is a great example of a digital tool designed to promote student learning and creativity through playing with 3 basic colors and seeing how they combine to create every other color available.
This project the meets requirements from Standard 2 by:
- Designing a relevant learning experience that incorporates digital tools to promote student learning/creativity.
Below is a java applet that should display the color changing program. If it’s not running, try downloading the executable jar file instead.
