abstract = {Attempts to define ill-defined domains in intelligent tutoring system (ITS) research has been approached a number of times (Fournier-Viger, Nkambou, & Nguifo, 2010; Lynch, Ashley, Pinkwart, & Aleven, 2009; Mitrovic & Weerasinghe, 2009; Jacovina, Snow, Dai, & McNamara, 2015; Woods, Stensrud, Wray, Haley, & Jones, 2015). Related research has tried to determine levels of ill-definedness for a domain (Le, Loll, & Pinkwart, 2013). Despite such attempts, the field has not yet converged on common guidelines to distinguish between well-defined versus ill-defined domains. We argue that such guidelines struggle to converge because a domain is too large to meaningfully categorize: every domain contains a mixture of well-defined and ill-defined tasks. While the co-existence of well-defined and ill-defined tasks in a single domain is nearly universally-agreed upon by researchers; this key point is often quickly buried by an extensive discussion about what makes certain domain tasks ill-defined (e.g., disagreement about ideal solutions, multiple solution paths). In this chapter, we first take a step back to consider what is meant by a domain in the context of learning. Next, based on this definition for a domain, we map out the components that are in a learning domain, since each component may have ill-defined parts. This leads into a discussion about the strategies that have been used to make ill-defined domains tractable for certain types of pedagogy. Examples of ITS research that applies these strategies are noted. Finally, we conclude with practical how-to considerations and open research questions for approaching ill-defined domains. This chapter should be considered a companion piece to our chapter in the prior volume of this series (Nye, Goldberg, & Hu, 2015). This chapter focuses on how to understand and transform ill-defined parts of domains, while the prior chapter discusses commonly-used learning tasks and authoring approaches for both well-defined and ill-defined tasks. As such, this chapter is intended to help the learner understand if and how different parts of the domain are ill-defined (and what to do about them). The companion piece in the authoring tools volume discusses different categories of well and ill-defined tasks, from the standpoint of attempting to author and maintain an ITS.},

abstract = {Compared to many other learning technologies, intelligent tutoring systems (ITSs) have a distinct challenge: authoring an adaptive inner loop that provides pedagogical support on one or more learning tasks. This coupling of tutoring behavior to student interaction with a learning task means that authoring tools need to reflect both the learning task and the ITS pedagogy. To explore this issue, common learning activities in intelligent tutoring need to be categorized and analyzed for the information that is required to tutor each task. The types of learning activities considered cover a large range: step-by-step problem solving, bug repair, building generative functions (e.g., computer code), structured argumentation, self-reflection, short question answering, essay writing, classification, semantic matching, representation mapping (e.g., graph to equation), concept map revision, choice scenarios, simulated process scenarios, motor skills practice, collaborative discussion, collaborative design, and team coordination tasks. These different tasks imply a need for different authoring tools and processes used to create tutoring systems for each task. In this chapter, we consider three facets of authoring: 1) the minimum information required to create the task, 2) the minimum information needed to implement common pedagogical strategies, 3) the expertise required for each type of information. The goal of this analysis is to present a roadmap of effective practices in authoring tool interfaces for each tutoring task considered. A long-term vision for ITSs is to have generalizable authoring tools, which could be used to rapidly create content for a variety of ITSs. However, it is as-yet unclear if this goal is even attainable. Authoring tools have a number of serious challenges, from the standpoint of generalizability. These challenges include the domain, the data format, and the author. First, different ITS domains require different sets of authoring tools, because they have different learning tasks. Tools that are convenient for embedding tutoring in a 3D virtual world are completely different than ones that make it convenient to add tutoring to a system for practicing essay-writing, for example. Second, the data produced by an authoring tool needs to be consumed by an ITS that will make pedagogical decisions. As such, at least some of the data is specific to the pedagogy of the ITS, rather than directly reflecting domain content. As a simple example, if an ITS uses text hints, those hints need to be authored, but some systems may just highlight errors rather than providing text hints. As such, the first system actually needs more content authored and represented as data. With that said, typical ITSs use a relatively small and uniform set of authored content to interact with learners, such as correctness feedback, corrections, and hints (VanLehn, 2006). Third, different authors may need different tools (Nye, Rahman, Yang, Hays, Cai, Graesser, & Hu, 2014). This means that even the same content may need distinct authoring tools that match the expertise of different authors. In this chapter, we are focusing primarily on the first challenge: differences in domains. In particular, our stance is that the “content domain” is too coarse-grained to allow much reuse between authoring tools. This is because, to a significant extent, content domains are simply names for related content. However, the skills and pedagogy for the same domain can vary drastically across different topics and expertise levels. For example, Algebra and Geometry are both high-school level math domains. However, in geometry, graphical depictions (e.g., shapes, angles) are a central aspect of the pedagogy, while Algebra tends to use graphics very differently (e.g., coordinate plots). As such, some learning tasks tend to be shared between those subdomains (e.g., equation-solving) and other tasks are not (e.g., classifying shapes). This raises the central point of our paper: the learning tasks for a domain define how we author content for that domain. For example, while Algebra does not involve recognizing many shapes, understanding the elements of architecture involves recognizing a variety of basic and advanced shapes and forms. In total, this means that no single whole-cloth authoring tool will work well for any pair of Algebra, Geometry, and Architectural Forms. However, it also implies that a reasonable number of task-specific tools for each learning task might allow authoring for all three domains. To do this, we need to understand the common learning tasks for domains taught using ITS, and why those tasks are applied to those domains. In the following sections, we identify and categorize common learning tasks for different ITS domains. Then, we extract common principles for those learning tasks. Finally, we suggest a set of general learning activities that might be used to tutor a large number of domains.},

Compared to many other learning technologies, intelligent tutoring systems (ITSs) have a distinct challenge: authoring an adaptive inner loop that provides pedagogical support on one or more learning tasks. This coupling of tutoring behavior to student interaction with a learning task means that authoring tools need to reflect both the learning task and the ITS pedagogy. To explore this issue, common learning activities in intelligent tutoring need to be categorized and analyzed for the information that is required to tutor each task. The types of learning activities considered cover a large range: step-by-step problem solving, bug repair, building generative functions (e.g., computer code), structured argumentation, self-reflection, short question answering, essay writing, classification, semantic matching, representation mapping (e.g., graph to equation), concept map revision, choice scenarios, simulated process scenarios, motor skills practice, collaborative discussion, collaborative design, and team coordination tasks.
