The reason that the Common Core will be replaced in about five years

I came across this article that reflects what is my biggest concern with education today:  Text book and testing companies need new movements in education to come up with new materials to sell.  

Education Week reports:

A new survey by an education marketing organization finds that school districts are making a top priority of shifting materials, instruction and assessments to reflect the Common Core State Standards. 

That's not too surprising, of course, given that all but four states have adopted the standards. But it offers yet another thermometer of sorts to measure the level of attention and activity around the new standards. My colleague Michele Molnar has the details for you over at the Marketplace K-12 blog. She's reporting on a sneak preview of the MDR survey, based on the feedback of about 500 curriculum and technology directors, which will be out in its full form later this month. 

Among the findings? Modifying curriculum and instruction to meet the common core topped the list of district priorities, with 84 percent saying that was a "high" priority. Close behind was modifying assessments to reflect the core, which 79 percent rated a high priority. 

Sixty-eight percent of the districts reported that they plan to buy new curriculum materials for the common core, and 76 percent said they are planning to obtain free materials from the two assessment consortia, PARCC and Smarter Balanced. Two-thirds, though, said they were planning to create their own instructional materials.

Cory Heidelberger reported several months ago about the costs of going to the Common Core for a state that doesn't seemed concerned about paying competitive wages for teachers.  This does a lot for companies like Prentice Hall and Glencoe/Mc-Graw Hill but little for the classroom.
