Produced by: Richard Paul There's an unusual phenomenon popping up in schools across the country -- educational software is almost never used in a classroom beyond the 8th grade. From pre-school to 8th grade, there is widespread use of specially-designed software to teach math, reading, grammar, and languages, but you'd be hard-pressed to find any of it in high school. Producer Richard Paul talks to professors, teachers, psychologists and software developers on his quest to find out why educational software disappears after middle school.
