Rule-based expert systems to support step-by-step guidance in algebraic problem solving: The case of the tutor PAT2Math

作者：

Highlights：

• We described the implementation of an expert system (ES) module of an Algebra ITS.

• The ES is composed by meta-rules that aim at reducing the number of possible paths to explore when correcting a student’s solution.

• We also described a quasi-experiment with 43 7th grade students.

• The students who interacted with our tool showed statistically higher scores on equation solving tests.
