Evidence of the month: August 2015
This meta-analysis looked at studies that compare learning outcomes for learners using Intelligent Tutoring Systems (ITS) with learners using other learning opportunities. They found 107 studies. They found:
ITS were associated with greater achievement when compared to teacher-led group instruction, other sorts of computer instruction and textbooks.
There was no significant difference in outcomes between ITS and small-group or individualised human tutors.
The positive findings applied across all levels of education, and regardless of whether ITS were used as the main means of teaching, a supplement, part of a teacher-led strategy, or as a homework aid.
This is not a new finding: previous work has come to broadly similar conclusions. But it is a recent and large in scope.
