        <p>This paper describes the purpose, goals, and guiding questions for the Adaptive Instructional System (AIS) standards workshop within the 2018 Intelligent Tutoring Systems (ITS) Conference Industry Track. Adaptive instructional systems (AISs) use human variability, learner goals and preferences, and other learner/team attributes along with instructional conditions to develop/select appropriate strategies (domain-independent policies) and tactics (actions). The goal of adaptive instruction is to optimize learning, performance, retention, and the transfer of skills between training environments and the work or operational environment where the skills learned during training are to be applied. The Institute for Electrical and Electronics Engineers (IEEE) Learning Technologies Standards Committee (LTSC) established a study group in December 2017 to evaluate the efficacy of AIS standards and the authors of this paper proposed this workshop (and several others) to inform stakeholders and solicit their participation. The interaction with stakeholders at the ITS conference will be through the ideas presented in paper presentations and via an expert panel composed of the authors of this paper and other authors in this workshop.</p>

      <p>
        Adaptive instructional systems (AIS) are defined as: “computer-based systems that
guide learning experiences by tailoring instruction and recommendations based on the
goals, needs, and preferences of each learner in the context of domain learning
objectives” [
        <xref ref-type="bibr" rid="ref1">1</xref>
        ]. Examples of adaptive instructional systems include, but may not be limited
to: intelligent tutoring systems (ITSs), intelligent mentors, recommender systems,
personal assistants for learning (PALs), and intelligent media (e.g., webpages) where the
content, frequency, and interaction (e.g., support) provided is tailored to the needs,
goals, and preferences of the learner or team of learners.
      </p>
      <p>In December 2017, the IEEE Learning Technologies Steering Committee (LTSC)
formed a 6-month Standards Study Group to investigate the possible market need for
standards across AISs. A recent AIS standards workshop in Orlando, Florida
highlighted several problems related to the authoring and maintenance of AISs that could
be resolved by improving the interoperability of AIS components. This paper discusses
the purpose, goals and guiding questions for AIS standards and is a companion
document to a live panel of experts who will discuss progress and opportunities for AIS
standards.

      <title>Workshop Purpose and Goals</title>
      <p>The purpose of this workshop is to educate AIS stakeholders about the IEEE study
group and expose them to some of the proposed approaches to standardization through
the paper presentations accepted for this workshop. A primary goal is to solicit
stakeholder participation in the study group and any resulting IEEE working groups formed
in the future in order to bring a diverse set of views and participation to bear in the
standardization process. Several interactions with stakeholder communities point to
broad interest in AIS standards. Discussions to date indicate opportunities to influence
their affordability, their interoperability and reuse, making them more appealing
learning technology solutions for the masses. By the time of this presentation at the ITS
conference, we will also have additional information to share about any proposals for
working groups.</p>
      <p>Through an interactive process, the expert panel will provide insight on activities to
standardize terms, elements and functions of AISs. The panel members will interact
with ITS Conference audience to answer questions and receive feedback from AIS
stakeholders.

      <title>Guiding Questions for AIS Standardization</title>
      <p>
        Several areas of AIS technologies are potential candidates for standardization. Robson,
Sottilare &amp; Barr [
        <xref ref-type="bibr" rid="ref2">2</xref>
        ] posed three essential questions to be considered during the IEEE
standardization development process:
• What do we want our standard(s) to do?
• What do successful standards look like?
• What is the appropriate process for developing standards?
3.1
      </p>
      <sec id="sec-3-1">
        <title>What do we want our standard(s) to do?</title>
        <p>The primary answer to this question is “solve marketplace problems”. There must be a
perceived value for any standard which is greater than the cost of implementing it.
Another driver is breakeven. Typically, business decisions (e.g., implement or don’t
implement a standard) are based on the premise of breaking even within two years. If the
cost of the standard is so high that it takes longer than two years to get to a breakeven
point, it is likely that the standard will not be implemented. This is especially true if
there are other ways to solve the problem (e.g., innovation). If the standard (e.g.,
interoperability, quality, convenience, or usability) solves a problem and does it with
minimal cost or requires only a short amount of time to recover the investment, the
standard will be perceived to have value.
3.2</p>
      </sec>
      <sec id="sec-3-2">
        <title>What do successful standards look like?</title>
        <p>Given that we (as developers of standards) believe our standard has value, what is a
reasonable measure of its success? Successful standards are adopted in relevant
markets and are sustained in those markets. Sometimes standards are adopted based on
policy, but the policymakers may be short-sighted with respect to the long term value
of the standard. The persistence of a standard in the marketplace is a sign of value and
a measure of a successful standard.</p>
        <p>Other measures of a successful standard are the diversity of the community of
interest who participate in the development of the standard and who ultimately adopt the
standard. It is critical that the working group that develops the standard are fully
representative of the global community who are intended to adopt the standard.
Representation from governments, industry members, and academics are one dimension of
diversity. Another dimension of diversity are the countries and regions of the global
community.
3.3</p>
      </sec>
      <sec id="sec-3-3">
        <title>What is the appropriate process for developing standards?</title>
        <p>The journey can often be as important as the destination when it comes to the
standardization process. We advocate for standards development through an open,
consensusbuilding process where all stakeholder groups are represented and active. This will
give AIS standards the best possible chance of being successfully adopted, will aid in
the growth and application of AIS technologies, enhance pathways for products to enter
the marketplace and reduce the probability that AIS standards will restrict innovation
and creativity in the AIS marketplace.

      <title>Discussion on Potential AIS Standards</title>
      <p>There are several AIS standards candidates that have been presented and discussed
during the six months that the IEEE AIS standards study group has existed. Workshops
like this one at ITS 2018 have engaged stakeholders and identified approaches ranging
from conceptual models to component interoperability to common data structures for
learner, domain, and instructional models. Below are four short descriptions of ideas
that seem to be taking hold and have potential to meet the criteria discussed in Section
3 of this paper:
• Common AIS Conceptual Model - a hierarchical common understanding of the
composition of AISs to aid engineers and scientists in communicating their designs and
ideas in lectures, presentations, and technical papers as well as in system
specifications
• AIS Component Interoperability and Reuse – a model of interoperability based on
the common AIS conceptual model to facilitate integration and reuse of components
through a set of common data messages
• Common AIS Learner Model Features – a hierarchical common understanding of
the most common features and their representation in both AIS short and long-term
learner models
• AIS Validation Standards – a testbed methodology to validate AIS compliance,
interoperability, and compatibility with adopted AIS standards, and assess AIS system
and component effectiveness</p>
      <p>Discussion within this workshop covers all of the potential AIS standards. Mr.
Avron Barr, IEEE LTSC, led off the AIS standards workshop with a presentation
centering on the IEEE standards process and specifically addressed why we need standards.
Mr. Barr also addressed the difficulties in the process and the characteristics of a good
standard. Following this discussion, we presented and discussed papers covering
standardization ideas with respect to:
•
•
•</p>
      <p>Component Interoperability (Sottilare &amp; Brawner, p. 55)
Learner &amp; Domain Models (McCoy, p. 63)</p>
      <p>Pedagogy (McCoy, p. 63, DeFalco, p. 73)</p>
      <p>
        The focus of Sottilare &amp; Brawner’s paper examined the use of the Generalized
Intelligent Framework for Tutoring (GIFT) [
        <xref ref-type="bibr" rid="ref3 ref4">3, 4</xref>
        ] as a model for examining how
component interoperability in AISs might work. In his presentation, Sottilare emphasized the
importance of GIFT’s modular architecture in component reuse across a variety of
GIFT-based tutors. McCoy made a pitch for common learner model and domain model
structures along with item analysis and assessment standards. Finally, DeFalco put
forward the idea of a metadata tagging schema based on a revision of Bloom’s cognitive
taxonomy [
        <xref ref-type="bibr" rid="ref5 ref6">5, 6</xref>
        ]. All of these ideas resonated with the workshop participants and
generated significant discussion.

      <title>Next Steps</title>
      <p>A project authorization request (PAR) was submitted to IEEE LTSC in May 2018 and
based on the plethora of activity in AIS stakeholder communities, we anticipated and
received approval for an IEEE AIS Working Group in June 2018. Next steps will
involve additional stakeholder recruiting to round out the diversity of the IEEE Project
2247 working group. Discussions about the organization, development of formal goals,
and assignment of roles and responsibilities should quickly follow. We anticipate the
development of a formal definition for AISs and a conceptual model for AISs that will
guide future AIS standards development.</p>
      <p>
        Also high on the agenda is understanding of what is and is not included in the family
of technologies known as AISs. This will help us examine appropriate exemplar
systems and discuss their attributes as part of standards discussions on conceptual models
and component interoperability. Since data-driven models are a hot topic, we anticipate
some discussion about the process of developing these types of models as a community
to speed their development [
