Research and Validity

Mathematics Navigator underscores the links among basic skills, problem solving, and conceptual understanding.  Although students must know how to add, subtract, multiply, and divide, they also need to know why these and other operations work.

Plenty of other organizations offer instructional or technology packages to boost weak math skills.  These approaches provide little or no improvement in student performance.  America’s Choice took the time to systematically investigate how the top-performing countries in the world teach even their lowest-performing students to do well in math.  We used research from National Mathematics Advisory Panel members Liping Ma, Deborah Ball, James Stigler, and Hung-His Wu.  

Drawing on that research, America’s Choice created Mathematics Navigator in close collaboration with an international team of researchers. We partnered with the Shell Centre for Mathematical Education at the University of Nottingham to focus particularly on the importance of prior knowledge and misconceptions.

The formative assessment system—developed in partnership with the Australian Council for Educational Research (ACER)—offers teachers a powerful means to identify problems in learning, monitor student, and differentiate instruction.  ACER, an international leader in education assessment, helped develop items for the Trends in Mathematics and Science Study (TIMSS) and created the Programme for International Student Assessment (PISA).
