J.F. Pane and B.A. Myers, "The Impact of Human-Centered Features on the Usability of a Programming System for Children," CHI 2002 Extended Abstracts: Conference on Human Factors in Computing Systems, Minneapolis, MN: ACM Press, April 20-25, 2002, pp. 684-685.
HANDS is a new programming system for children that was designed for usability. This paper examines the effectiveness of three features of HANDS: queries, aggregate operations, and data visibility. The system is compared with a limited version that lacks these features. In the limited version, programmers can achieve the same results but must use more traditional programming techniques. Children using the full-featured HANDS system performed significantly better than their peers who used the limited version. This provides evidence that usability of programming systems can be improved by including these features.
