One way to gauge what could actually occur in American K-12 education between now and 2030 is to recall some of what did occur over the previous two decades, i.e. between 1990 and 2010. Recounted here are ten such developments. All were in some sense “national” but only three engaged the federal government to an appreciable degree. The others seeped, slithered, morphed, and metastasized from place to place via mechanisms that have more to do with the culture of education than with its formal governance.
