Research: Additional Key Research

Additional Key Research that Affected the Development of Perceptions Math's Curriculum & Manipulatives

Research1 has shown that understanding fractions and whole-number division are early predictors of a student’s mathematical achievement in high school.  The research further supports that mastery of fractions and division is important to develop an understanding of algebra and other high school mathematics. Watch a video of Dr. Seigler discussing the study and the implications. Research2 has also shown that an intervention should include explicit instruction that is systematic, cumulative, and multi-sensory.  Additionally, interventionists should be proficient in the use of visual representations of mathematical ideas. The Preceptions Program uses MasterPieces and MasterFractions to support the instruction of place value, addition, subtraction, regrouping, multiplication, division, and fractions, and much more consistent with these research findings.
