Realizing XML Driven Algorithm Visualization

AbstractIn this paper we describe work in progress on JHAVÉ-II, a new generation of the client-server based algorithm visualization system JHAVÉ. We believe this to be the first algorithm visualization system to be totally XML driven. We describe the XML scripting language visualization authors can use with JHAVÉ-II to define the sequence of graphical snapshots, integrated pop-up questions, synchronized pseudocode, and supplemental information that comprise a particular algorithm visualization. JHAVÉ-II then uses these scripts to render visualizations and support student exploration of algorithms

Do Clothing Style and Color Affect Our Perceptions of Others?

Prior research has shown that women who wear red clothing or suggestive clothing are perceived as more attractive, having greater sexual intent, and having more negative qualities than women dressed in different colors or less suggestive clothing. This bias towards perceiving sexual intent may be evolutionary or may be due to people projecting their emotions onto others. The current study builds from this research by performing a 2 (color: white or red) x 2 (clothing type: suggestive or non-suggestive) between-subjects experiment. We hypothesized that women would be perceived as more attractive and as having greater sexual intent while wearing red and suggestive clothing rather than while wearing red and non-suggestive clothing or while in either of the white clothing conditions. Although we found no significant interaction between the color and clothing conditions, we did find multiple main effects. This suggests that either the color red or the suggestive clothing type will make a difference in perceptions of attractiveness and sexual intent, but when together, the effect is alleviated

Inservice Education of High School Computer Science Teachers

The United States urgently needs strong high school computer science programs. Our economy and the technological level of our society depend upon a continuing supply of high quality scientists, mathematicians, engineers, business people, computer scientists, and technicians, all equipped with a solid foundation in computer science. This supply depends upon a strong computer science program that begins in high school..
