This study aimed to investigate the effect of experimenting with physical manipulatives (PM), virtual manipulatives (VM), and a blended combination of PM and VM on undergraduate students' understanding of concepts in the domain of "Light and Color." A pre-post comparison study design was used for the purposes of this study that involved 70…

Discusses an activity in which computers with color monitors can be used to demonstrate light blending with relative ease. (MKR)

Discusses the nature of light and its relationship to color, particularly two models of color production: the additive and subtractive models. Explains the importance of these models for understanding how computers and printers generate colors. Argues that it is important to understand these processes given the prevalence of computers in art. (DSK)

The model for color vision put forward by Edwin Land is explained. The aspects of the theory that can be demonstrated within the classroom are described. A random arrangement of straight-edged colored areas mounted on a screen, called a Mondrian, projectors, and a computer are used to calculate reflectance. (KR)

Describes a student activity that focuses on color and the production of images on computer monitors. Students discover the rules for making colors through the use of a magnifying glass and a computer monitor. Includes some tips for integrating the activity into the curriculum. (DDR)

Discusses various types of transducers and explains the use of a photoresistor in sensing light. Describes various hardware and software combinations which can be used with photoresistors in science laboratory experiments. Presents general applications of this instrument in light-meter, solarimeter, and colorimeter experiments. (TW)
