Warren Buckleitner, editor of 'Children's Technology Review' and a doctor of educational psychology, has donated a representative sample of this diverse and still-growing medium. Learning has never been easier, nor so enjoyable. The entire Encyclopedia Britannica is now in digital format, allowing for easy searches. Video games such as Math Blasters allow children to explore fantastic worlds based on numbers and equations. High school students can electronically practice for the SATs, while aspiring lawyers can find sample LSAT questions. Software programs now teach children math, science, grammar, spelling, typing, and foreign languages. Counting games, alphabet blocks, and activity books have long been staples of 'fun learning,' and these have most recently been supplemented by educational technology. Parents, teachers, and other educators have continuously sought ways to instruct children in a fun and interactive way.
