ACT编程语言导师帮助学生编写简短的计算机程序。导师是围绕着一套几百个编程规则构建的，允许程序一步一步地与学生一起解决练习。本文评价了导师的学生建模过程，该过程采用了这些编程规则的叠加。导师根据学生的表现来估计学生学习每条规则的概率。这些评估用于指导补救和实现精通学习。评估了这些概率估计对后测和导师表现的预测效度。
The ACT Programming Languages Tutor helps students as they write short computer programs. The tutor is constructed around a set of several hundred programming rules that allows the program to solve exercises step-by-step along with the student. This paper evaluates the tutor's student modeling procedure which employs an overlay of these programming rules. The tutor maintains an estimate of the probability that the student has learned each rule, based on the student's performance. These estimates are used to guide remediation and implement mastery learning. The predictive validity of these probability estimates for posttest and tutor performance is assessed.
