Abstract: "We discuss our experience with an interface that gives users the ability to directly represent and manipulate goals at several levels of detail. The interface is built into Bridge, a tutorial environment for novice programmers. The name comes from our intended 'bridge' between novice and expert conceptions of programming. In order to understand student designs and partial programs, Bridge provides languages that allow a student to talk about his or her high-level designs and partial work. We call the vocabulary of these languages plans. Plans are bundles of knowledge about the standard subtasks in a domain, designed and organized based on a typical user's point of view."
