    ST Math Methodology & Impact

    A New Paradigm for EdTech Evaluation

    In the current edtech landscape, we rarely look beyond the one “gold standard” study for proof that a program is effective -- even if it’s many years old and only covers a single assessment. Here at MIND, we encourage everyone to raise their sights and look for a large number of studies, using recent program versions, garnering repeatable results on multiple state assessments, and over many varied districts. We believe a high volume of effectiveness studies is the future of a healthy market for product information in education.

    ST Math Methodology

    What is Z-Score?
    In order to compare changing state assessments year to year, we calculate z-scores for every grade across all years being analyzed, using full state data set of schools for the averages and standard deviations.

    The use of z-scores is a valid statistical method to normalize any dataset and enable analysis across otherwise uncomparable exams. All of our reports include both mean scale scores and their accompanying z-scores.

    Compared to lengthy, expensive RCTs (randomized controlled trials), organic quasi-experiments can study the adoption of a program as is, without the length and complexity of experiment planning. Methods of matching and comparing similar schools with and without the program can be made statistically rigorous and powerful. And if we study at the grade-level, we have the average state test performance data universally available. This is how we perform multiple annual, transparent evaluations of results of all ST Math school cohorts.

    States Studied Per Year

    since 2011

    120 studies across 27 states since 2011.

    *Some states had multiple studies within a calendar year
    The Importance of Effect Size

    Independent education research firm WestEd recently conducted a study of 3rd to 5th grades in more than 450 schools and 16 states. In the 14 states with schools that consistently implemented ST Math, the average effect size for math proficiency was .36, well above what is considered “substantively important" by the federal What Works Clearinghouse.
