The users who touched the ceiling of scratch

Abstract The Scratch programming environment is widely known for its high accessibility for novice users, especially children. Recently it has also been adopted in introductory computer science courses in universities where first empirical results show that users with prior programming experience were less satisfied than others. In this paper we analyze this specific aspect by identifying difficulties that experienced programmers had with Scratch during a four-day workshop. The experiences of this particular user group suggest adding some standard integrated development environment features to Scratch. Beyond these results we argue that this obvious route might hide the real problem of discoverability of Scratch's features.
