6．The event was part of a national educational （51）Bin computer coding instruction that is growing at Internet speeds．Since December，20，000 teachers from kindergarten through 12
th grade have（52）A coding lessons，according to Code．org，a group backed by the techindustry that offers free curriculums．（53）A，some 30 school districts have agreed to add coding classes in the fall．And policy makers innine states have begun awarding the same （54）C for computer science classes that they do for basic math and science courses，rather than treating them as optional courses．
It is a remarkable change for computer science．Smartphones and apps are commonplace now，and engineering careers are（55）D．To many parents，coding looks more like a basic life skill，one that might someday （56）D a great job or even instant riches．
The spread of coding instruction，（57）B just new，is"never known-there's never been a move this fast in education，"said Elliot Soloway，a professor of education and computerscience at the University of Michigan．He sees it as very positive，（58）C inspiring students to develop a new passion，perhaps the way that teaching frog dissection （解剖） may inspire future surgeons and biologists．
But the exposure to early coding comes with （59）A，too．It is not clear that teaching basiccomputer science in grade school will beget future jobs or encourage（60）D creativity and logical thinking．And particularly for younger children，Dr．Soloway said，the activity is more like a video game，but not likely to impart actual programming skills．A coding curriculum，（61）B by Code．Org．，combines basic instruction with videogames involving Angry Birds and hungry zombies．The lessons do not（62）B traditional computer language．Rather，they use simple wordcommands-like"move forward"or"turn right"-that children can click on and move around，to （63）D an Angry Bird to capture a pig．
The movement comes with no shortage of"we're changing the world"marketing passion from Silicon Valley．"This is strategically（64）Cfor the economy of the United States，"said JohnPearce，a technology businessman who has started a nonprofit，MV Gate，with Jeff Leane，to bring youth and family coding courses developed by Code．org to MillValley．Parents love the idea of giving children something to do with computers that they see as （65）C，Mr．Pearce said．"I can't take my kid playing one more hour of video games，but if the children are exploring coding，I tell him I can live with that all night long．"
