Using passwords to keep student data safe is important, but teachers are getting smart about helping young students by using QR codes instead coping with impossible to remember and often difficult to type nine or ten digit passwords that are needed to start up computers and other digital devices. Lots of other changes in the classroom this fall are giving teachers more ways to use apps based on their student’s needs as well, including using sites like Newsela, a program which takes news articles and rewrites them for reading levels from second grade through high school. Right now, more than 850,000 teachers and 9 million students in the U.S. use the program.
