There has been little research into how end-user programming environments can provide explanations that could fill a critical information gap for end-user debuggers -- help with debugging strategy. To address this need, we designed and prototyped a video-based approach for explaining debugging strategy, and accompanied it with a text-only approach. We then conducted a qualitative empirical study with end-user debuggers. The results reveal the influences of the explanations on end-user debuggers'' decision making, how users reacted to the video versus textual media, and the information gaps the explanations closed. The results also reveal issues of particular importance to explanations of this type.
