Abstract
What type of oral reading assistance is most effective for a given student on a given word? We analyze 189,039 randomized trials of a within-subject experiment to compare the effects of several types of help in the 2002-2003 version of Project LISTEN's Reading Tutor. The independent variable is the type of help given on a word. The outcome variable is the student?s performance at the next encounter of that word, as measured by automatic speech recognition. Training a help selection policy sensitive to student or word level improves this outcome by a projected 4% - a substantial effect for picking a single better intervention.
