We describe work on developing workshop activities that are part of wConnect, a project that is building an online community of women in computer and information science. The workshops are designed by college women for high school girls, with hands-on construction of dynamic web sites. Because of limited workshop time, the activities use scaffolding to help girls achieve the intended learning objectives. In this paper we describe the design of the activities, their formative evaluation in a series of four workshops, and how we are using these results in the larger project.
