The first two high schools to use Get More Math ranked in the top 10 in PA for PVAAS growth on the Keystone Algebra test – out of 700 schools!
In this PVAAS sample, the students represented by blue bars were expected to pass and those in red were expected to fail. The green bars show the improvement over the expected results. Note that 53% were expected to attain the 1500 required for 'Proficient,' but in actuality, 85% did so!
How GMM Works
GMM builds math practice sessions for each student that include both new material and a thorough review of old concepts and skills. As the year progresses, the teacher gradually selects more types of problems for these sessions. Every day, a student sees a new mix of practice problems selected for her based on data collected during all her former sessions. Is she weak on graphing? There will be a graphing problem. Is she a champ at multiplying decimals? Then she will see fewer problems of that type, although occasionally GMM will include one to make sure she still remembers. GMM selects her problems for a session based on her weaknesses and also the amount of time since she last worked on each problem type.
Most math software fails to adequately address long-term retention. A common (flawed) paradigm is to measure student ability by results from a concentrated burst of problems on a specific skill. For example, a student might in one session do 10 consecutive adding fraction problems. Suppose she has no further practice of that skill for a week and then she takes a quiz. We cannot say with confidence that she will retain her accuracy. Now suppose she takes a high- stakes test five months later: she may have completely lost the skill.
GMM addresses this problem. It ensures that each student regularly revisits skills from the entire curriculum and will only designate a student as ‘high level’ on a skill based on consistently strong performance throughout the course.
