许多系统旨在帮助想要学习编程的小说，但很少有人支持那些对学习（更多）编程不感兴趣的人。当他们需要克服障碍时，如何帮助像这样的EUP学习一点。在42个青少年中，有42个青少年是隐式可行的提示与明确行动的提示的完整角色，以及在这些原则下的无上下文敏感性的重要性。比以前的营地要在相同的时间内学习相同数量的材料。
Many systems are designed to help novices who want to learn programming, but few support those who are not interested in learning (more) programming. This paper targets the subset of end-user programmers (EUPs) in this category. We present a set of principles on how to help EUPs like this learn just a little when they need to overcome a barrier. We then in stantiate the principles in a prototype and empirically investigate the principles in two studies: a formative think-aloud study and a pair of summer camps attended by 42 teens. Among the surpris ing results were the complementary roles of implicitly actionable hints versus explicitly actionable hints, and the importance of both context-free and context-sensitive availability. Under these principles, the camp participants required significantly less in person help than in a previous camp to learn the same amount of material in the same amount of time.
