For the Color Sleuth lesson/project, has anyone considered ways to prepare for helping students who have one or another form of color blindness?
Great that you’re thinking about making sure the activity is accessible to students with color blindness.
I hadn’t thought about it really and this may be a totally naive way to approach it, but I figured I would just have the student do the same project but “easier”, as in have their program start out with a larger difference in colors.
Another possibility (that again, I haven’t fully thought through), is to have them create something else to compare, like circles of slightly different radii. Or different color and different radii, so the player can go off either/both cues.
In terms of playing the game it is really about detecting a difference in brightness not color. The difference color can be a slightly different hue do to how color works when you add 20 to each channel, but in general the color is irrelevant.
We had a color blind student in our class and it did not present a problem…As a previous poster mentioned, it detecting a difference in brightness
I heard from a teacher who shared that this activity actually lead to a student discovering that they were colorblind. They did those tests with the circles with color dots.
