One feature that makes an Intelligent Tutoring System (ITS) hard to build is strategy freedom, where students are able to pursue multiple solution strategies within a given problem.. But does greater freedom mean that students learn more robustly? We developed three versions of the same ITS for solving linear equations that differed only in the amount of freedom. We conducted a study in two US middle...
