This subtopic covers specification of interfaces that allow the modules within the system of systems to interact. These interfaces often leverage standards for learning technology integration.
Interfaces need not be technology-based. They may also be defined as organizational protocols, i.e. how people within an organization interact, or as pedagogical protocols, i.e. communication between instructors and learners for carrying out a certain pedagogical method with fidelity. For example, how teachers interact with students while employing the Socratic method could be understood as an interface standard with a designed pattern of interactions, predictable kinds of data to be exchangedm and a defined set of rules, e.g.
Socratic Method Protocol Rules
- Turn-taking: Exchanges alternate (Teacher question → Student response → Teacher probe → Student revision).
- Non-adversarial stance: Teacher seeks clarity, not victory.
- Error tolerance: Students are permitted (and encouraged) to explore incomplete or uncertain answers.
- Transparency: Teacher avoids “gotcha” traps; intent is always to guide thinking.
- Adaptivity: Teacher modulates depth and pace based on student’s reasoning capacity.
Socratic Method Data Packets (Content Types)
-
Questions (why, how, what if, what follows)
-
Responses (claims, examples, analogies, counterexamples)
-
Meta-questions (about assumptions, consistency, scope)
-
Reflections (student self-assessment of reasoning)

Design principles for virtual humans in educational technology environments — Scotty D. Craig, Nicolaus L. Schroeder (2018). International Journal of Artificial Intelligence in Education · doi:10.1007/s40593-017-0148-y · ~150 citations · tier: contemporary
Synthesized human-factors engineering principles for designing pedagogical agents. Showed that voice, appearance, and persona of virtual instructors systematically affect learner cognitive load and perceived credibility — establishing that LE must integrate psychological design alongside algorithmic design.

The voice quality of pedagogical agent impacts learning and agent perceptions — Ryan F. Siegle, Scotty D. Craig (2024). Journal of Computer Assisted Learning · doi:10.1111/jcal.12997 · ~20 citations · tier: contemporary
Empirically demonstrated that voice quality (prosody, naturalness, warmth) of a pedagogical agent significantly affects both learning outcomes and learner perception. Illustrates the meticulous human factors engineering required in modern AI-driven learning systems.
