A common approach for introducing computer science to middle school students is to teach them a simple yet engaging programming language A different approach is to teach them some advanced topic independent of any particular language or syntax We describe a 3-hour workshop module designed to do both This module has been piloted with a group of thirty 8th grade girls. It uses the Scratch programming language to develop the advanced software engineering concepts of specifications, refinement, and composition After this module, students were enthusiastic about continuing to program in Scratch independently and also felt they learned something about computer science as a discipline.
