Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q1 i? Astus's pedagogical module automatically generates the pedagogical content for next-step hints, while TDK and CTAT require hint messages to be authored in the model of the task. → Luc Paquette 2015 q1 i? Astus contextualizes generated hints to the current state of the task case using the episodic tree. → Luc Paquette 2015 (2)

q1 · i? · design · r2

Design-level analysis of MTT frameworks (TDK, CTAT) versus Astus presented in the article's introduction. The authoring-process comparison shows that CTAT-style tutors embed hint templates in task-model production rules, whereas Astus generates hint content from the task model, as stated: "those frameworks require that their pedagogical content" be authored while Astus generates it.

"those frameworks require that their pedagogical content (hint messages and common errors) be included in the model of the task whereas Astus ’s pedagogical module automatically generates it"

q1 · i? · design · r2

Analytical description of Astus's hint generation mechanism in the Model Tracing in Astus section. The episodic tree, instantiated from the procedural graph according to the state of the knowledge base, lets generated hints reflect completed and waiting sub-goals, so that "Astus to contextualize the hints it generates according to the current state of the task case."

"Using the content of the episodic tree allows Astus to contextualize the hints it generates according to the current state of the task case."
