Open educational resources (OER) are seen as part of the solution to course material affordability. The National Council of Teachers of Mathematics (NTCM) has issued a warning that too many open resources are not necessarily a good thing.
In its official position, the organization recognized that OER can stimulate discussions among teachers, allowing them to form communities to share ideas and compare results. NTCM also pointed out that OER can provide teachers with ways to use innovative technology.
At the same time, NTCM warned that OER can be difficult to organize and the resources students have access to can vary by teacher and school. Another risk is the potential for schools to drop the vetting process of the resources.
“A coherent, well-articulated curriculum is an essential tool for guiding teacher collaboration, goal-setting, analysis of student thinking, and implementation,” NTCM said in the release. “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.”
