What platforms and systems do learning engineers build on?
Authoring environment for building intelligent tutoring systems with cognitive models. Allows learning engineers to encode expert knowledge as production rules and knowledge components, then test those models against student interaction data.
Caliper is xAPI's closest sibling — a learning-analytics interop standard from 1EdTech. If you're picking an LMS analytics stack, you'll encounter both.
Open repository of educational datasets and analysis tools. Hosts interaction data from intelligent tutoring systems and supports Learning Factors Analysis, knowledge component modeling, and educational data mining at scale.
Open-source framework for authoring, delivering, and assessing intelligent tutoring systems. Army-funded; widely used in defense and adjacent workforce training contexts.
The de facto standard for learning-event instrumentation. Every LE platform conversation eventually comes back to xAPI. Runs through the IEEE LTSC, where much of ICICLE's standards work also happens.
Commercial learning-engineering platform spanning xAPI data design, instrumentation, and evaluation. One of the few vendors building tools explicitly for the LE workflow rather than generic ed-tech analytics.
