The Chicago Public School system moves computer science from the world of electives and after-school clubs to a part of the core cirrculum, starting with students as young as kindergarteners, via Edtech:
For so long, K–12 education has focused on the basic humanities and sciences. That usually meant that core subjects were English, history, math and a laboratory science of some kind. Computer science, if it was offered, was usually an elective class in middle or high school, often focused on acclimating kids to using software rather than creating their own.
But Chicago is poised to bump up computer science into the core curriculum, according to a report from the Chicago Sun-Times.
