Educational Impact Calculator:
A Tool for Education Consumers
Each year, educational consumers – teachers, school administrators, policy makers, and parents – receive reports of how well their students have scored on state assessments and, often, other tests. There are many questions they may want to answer: Are our students doing better (or worse) than those in other schools? Are they doing better this year than last year? Are recent changes in my school different than the changes in other schools? Perhaps, most important, are the differences large enough to be considered educationally important? Could they have just occurred by chance?
The research community has well
developed methods and criteria to answer these questions, but most educational
consumers are far from comfortable with the underlying calculations and
statistical procedures. They may be left wondering what the assessment results
mean and feel that they are at the mercy of researchers and other “experts” to
calculate statistics and interpret the data. The Educational Impact
Calculator (EIC) is designed to help break the barrier between the “experts”
and the consumers, empowering those who are closest to the data to answer
questions regarding assessment results. It
Itprovides a simple way for educational consumers to use publicly available data to determine if changing achievement patterns in their school would meet the criteria researchers use to denote educationally important and statistically significant results.
