Maryland's approach to distance learning has been equally backward. Of the 31 states authorizing distance learning in public schools, Maryland has the second smallest program. Montgomery County, which leads in the use of distance learning in the state, has less than 1 percent of its students involved in such courses. There is highly limited use of "blended learning," where 20 percent to 80 percent of a course is given online, although it is of obvious value in language and math courses involving repetitive drills. Maryland also makes only limited use of "flipped classrooms" where lectures are given online, freeing classroom time for individualized instruction and assistance with homework. In 2009-2010, less than a tenth of one percent of Maryland students were enrolled in virtual courses, compared with 8.1 percent in Florida and more than 2 percent in six other states.
