A New Phase of Research in 2018
In April 2018, YiXue and SRI International announced an extension of their artificial intelligence research collaboration. YiXue is the company identified in Carnegie Mellon’s subsequent announcement as using the Squirrel AI Learning brand.
The 2018 announcement focused on virtual tutoring for students in China. It described a new phase of work to expand YiXue’s AI laboratory and explore how learning technology could support students and tutors.
Exploring Adaptive Tutoring
The research areas described in the announcement included artificial intelligence, natural language technology, emotion detection, and learning-system design. The stated aims included studying engagement, learning efficiency, and learning outcomes.
The announcement also discussed an environment combining online tutoring technology with human tutors. That is a useful context for understanding the work: the research addressed a learning experience with both technological and human elements.
These were the areas and goals reported in 2018. They should be read as a historical research announcement rather than a description of every feature available in today’s learning centers.
From Research Goals to Evaluation
SRI returned to the relationship in its January 2022 education newsletter. It described work with YiXue, also known as Squirrel AI, on rapid and rigorous evaluations of the adaptive tutoring system.
According to SRI, those evaluations examined student learning, engagement, and factors associated with outcomes. Its broader discussion of AI in education emphasized tools that complement adults and strengthen connections among children, adults, and learning content.
For readers considering adaptive education, evaluation is an essential part of the conversation. Questions about how a tool is studied, which learners participate, and what outcomes are measured help make research findings easier to understand.
Taken together, the 2018 announcement and SRI’s later newsletter show two stages of that conversation: defining research goals and examining learning experiences through evaluation.
