This page is the canonical source for wiki terminology.
Core Content Terms
| Term |
Canonical Definition |
| Lesson |
The learner-facing content item shown on the dashboard. In authoring/upload terms, a lesson is the uploaded TDF package (TDF + stimulus file + optional assets such as images/audio/video). |
| TutorScript |
JSON authoring language for lesson packages, including SPARC documents and production rules. |
| SPARC document |
Declarative instructional page with stable nodes, learner-action mappings, working-memory facts, and executable rules. |
| Production rule |
Conditions and optional tests over working-memory facts, followed by effects such as feedback, model practice, document changes, or an instructional decision. |
| Knowledge component (KC) |
Author-defined concept or skill identity used to group learning evidence. |
| TDF |
Tutor Definition File. JSON configuration that defines lesson structure and behavior (tutor.setspec, tutor.unit, deliverySettings, session objects, etc.). |
| TDF package |
The ZIP upload bundle containing at minimum a TDF and its referenced stimulus file, plus optional assets. |
| Root TDF |
The primary TDF entry for a lesson that can include randomized condition variants (sub-TDFs). |
| Sub-TDF |
A condition variant under a root TDF, typically tracked for assignment/counts rather than shown as a separate lesson. |
Stimulus Terms
| Term |
Canonical Definition |
| Stimulus file |
JSON content file referenced by setspec.stimulusfile; stores the instructional items/questions and answer data. |
| Canonical media reference |
The expected asset identifier/reference generated by upload/conversion flows; authoring should target canonical references, not non-canonical filename recovery behavior. |
| Cluster |
A group of one or more related stimuli (stims) in the stimulus file. Many scheduling rules select at the cluster level (for example clusterlist). |
| Stim / stims |
A single stimulus entry (stim) or the array of stimulus entries (stims) inside a cluster. A stim contains fields like display and response. |
| Schedule |
The generated per-student sequence of assessment trials produced from an assessmentsession template. |
| Group template |
In assessment sessions, the conditiontemplatesbygroup pattern that defines how clusters repeat and are positioned. |
| AutoTutor session |
Conversational unit configured with autotutorsession; reads an authored autoTutor script from the first stim in its configured cluster. |
| H5P historical records |
Retained records from the removed H5P display runtime; new H5P authoring/upload/playback is unsupported. |
| Condition-root export |
A report/export scope that can include multiple related condition branches for a root lesson target. |
| Unit template |
A reusable unit definition stored in setspec.unitTemplate, commonly used by adaptive video logic. |
Settings Scope Terms
| Term |
Canonical Definition |
deliverySettings |
Unified learner-runtime settings for timing, sequencing, feedback, answer controls, prompt presentation, and related lesson behavior. It can appear at tutor.deliverySettings, tutor.unit[].deliverySettings, and tutor.setspec.unitTemplate[].deliverySettings. |
| Legacy delivery setting names |
Older content and historical docs may use deliveryparams and uiSettings. New authoring should use deliverySettings. |
d(x, y) |
Data-export helper notation meaning: use x if present; otherwise use explicit alternate value y. |
Audio/API Flow Terms
| Term |
Canonical Definition |
| Embedded API keys |
Lesson-embedded speechAPIKey / textToSpeechAPIKey from TDF setspec; used directly when route/config enables embedded-key mode. |
| Account menu |
The top-right authenticated user menu that shows avatar, display name, role, and user actions such as Profile, Audio settings, theme selection, and Log out. |
| Profile |
User settings page reached from the Account menu; stores private account name, public display name/avatar, and personal OpenRouter settings. |
| Profile flow |
Standard logged-in learner flow where speech recognition normally uses the learner personal speech key (Meteor.user().speechAPIKey) unless embedded-key mode is enabled. |
| OpenRouter profile settings |
Personal OpenRouter API key and default model managed from Profile for AutoTutor and AI-assisted content creation workflows. The key is stored encrypted on the MoFaCTS server and returned to the browser for client-side OpenRouter requests. |
| Experiment logins |
Login/entry routes that enable embedded-key mode (useEmbeddedAPIKeys = true) so lesson-embedded keys are used directly. |
