High School Reviews:

“KleenSlate dry erase paddles help teachers spot those lagging behind without embarrassing them by drilling them during class. If at least 80 percent of the class gives the correct answer, the teacher moves on. Teachers identify those students who don’t understand and can work with them separately. And students who have trouble with a subject can take an elective class that helps them keep up. If less than 80 percent of the class understands a lesson, the instructor teaches it again. The technique has helped students such as a senior Krista Montgomery, 18, who wrestled with algebra.

“I knew I was struggling, but I’m not the type to go up and ask for help,” she said. “This way, teachers know if I’m struggling.”

“Kids who don’t know (answers) try to be invisible, but you cannot be invisible here.” Waterford High’s Vice Principal
