National Math Teachers Council Warns of OER Risks -- THE Journal

"The National Council of Teachers of Mathematics (NCTM) released a statementlast week warning of the risks involved in relying too heavily on open educational resources, or OER.

The NCTM published its official position, emphasizing coherence and quality. It reads like this:

'A coherent, well-articulated curriculum is an essential tool for guiding teacher collaboration, goal-setting, analysis of student thinking, and implementation. In a time when open educational resources are increasingly available, it is imperative that teachers be provided with curricular materials that clearly lay out well-reasoned organizations of student learning progressions with regard to mathematical content and reasoning.'"
