Abstract

So often in classes that teach the non-science major students are “dog and pony” shows. The students watch demonstrations, they take notes, they supposedly “absorb” the information only to forget it after the next examination. These types of classes serve only as attempts to transfer information. But what if we give the students a toolbox that provides them with the ability to make their own observations about how light works. Then, the students are empowered to plan their experiments, manipulate the simple apparatus, make their own observations, and draw their own conclusions; more closely paralleling how scientists function. To succeed at this endeavor, we carefully designed a low cost toolbox for the students. Investigations include: Additive color mixing, digital colors and filters, shadows with colors, LED spectrum and spectra, light’s path, Polarization, Luminescence and Brightness, and simple optical instrumentation such as spectrometers. We created activities that give the students direction, but allow them freedom to explore and discover. Online forums/class discussion are also used to enhance their comprehension of their projects. Using this philosophy, we have had great success in both online and face to face classes.
