The study produced a translation of van Hiele levels into a detailed model that describes students’ levels of thinking discursively.

Teachers and other school district personnel have been charged with interpreting the expectations of NCLB and incorporating them into classroom practice. For many, state standards or grade level expectations (GLEs) now compete with the adopted text for classroom time and attention. In response to this shift, the Center for the Study of Mathematics Curriculum (CSMC) analyzed standards for more than forty states in the topics of number and operations, algebra, mathematical reasoning, geometry and measurement, and probability and statistics. Here, Horvath et al highlight some issues related to the content of standards in the middle grades (5-2) that emerged from the CSMC's analysis.
