This subtopic examines the importance of shared understandings among learning engineering practitioners from different domains, how terms from different domains can have different meanings or how contextual assumptions may hinder success. It is helpful for practitioners to be aware of examples of successful and failed collaboration due to gaps in understanding or communication breakdowns. The subtopic may include strategies for mitigating such failures.

Research Context

Shared understanding in cross-domain teams is not automatic: the same term can mean fundamentally different things to a cognitive scientist, a software engineer, and a classroom teacher, and these definitional gaps can silently derail collaborative projects [LE-LS-GL-003]. IEEE ICICLE has addressed this directly by developing a Learning Engineering Primer — a shared terminology document provided to all authors publishing in the Journal of Learning Engineering — to align vocabulary across the field's multidisciplinary contributor base [LE-LS-CO-001]. Herbert Simon's original framing anticipates this challenge: he argued that teaching expertise requires a distinct vocabulary and conceptual framework that differs from both the subject-matter expert's and the pure researcher's, and that building shared understanding across these communities is itself a core competency of learning engineering leadership [LE-LS-GL-001]. Kenneth Koedinger's collaborative development process for Cognitive Tutors required iterative negotiation between mathematical knowledge models (how experts organize content) and cognitive models (how novices acquire it) — a process that demanded shared language before shared tools could be built [LE-LS-PP-005].

From the Learning Engineering Toolkit

Shared understanding sits at the literal center of the Learning Engineering Toolkit's model of the field. In the book's "flower" diagram of the professional domains that a learning engineering problem may require, shared understanding occupies the hub around which the petals — from the learning sciences to software engineering to subject-matter expertise — are arranged [LET-00]. The book describes learning engineering as "a team process that builds on professional specialties within the engineering team as a coordinated effort rooted in a shared understanding and vocabulary" [LET-00].

Chapter 1 makes the same point about how teams actually function: the professionals on a team "require some shared understanding of the challenge and enough understanding about the other domains to effectively communicate as a team" [LET-01]. This connects shared understanding to the book's broader claim that team members need not be experts in every field; they need enough common ground to communicate across specialties [LET-01]. The Toolkit treats the development of this common ground as foundational, ranking "the development of the team culture, organizational processes, and a shared vocabulary" alongside individual talent development in importance [LET-00].

The book also illustrates why shared vocabulary matters in practice. At Carnegie Learning, cross-disciplinary "data jams" depend on participants from different backgrounds — data scientists, instructional designers, former teachers — being able to interpret the same data together; the book notes they "certainly need to basically understand how to think about data" even if they are not data scientists [LET-00]. Chapter 1's Electrostatic Playground story similarly shows subject-matter experts, developers, and researchers working to structure and encode ambiguous session data together before they could act on it, underscoring that shared understanding is something teams build deliberately rather than assume [LET-01].
