Natural language dialogues have been demonstrated to be effective for instruction in a variety of settings. However, previous research has demonstrated that the hierarchical structure of dialogue, which is a natural representation for linguists, is difficult for non-linguists to understand and work with. Even for linguists, it is possible to lose track of where one is in this hierarchical structure during authoring. We refer to difficulty in working with this hierarchical representation as the hierarchical navigation problem. In this short paper we present a simple but powerful tool designed to facilitate the authoring process, which includes innovative interface elements that specifically target the hierarchical navigation problem. Our user study demonstrates progress towards overcoming this difficulty.
