Are you challenged to involve parents in your school’s science curriculum? Ridgecrest Elementary School in Hyattsville, Maryland, tackled that issue and found a successful solution in an exciting program called “Playtime Is Science” (Sprung, Froschl, and Colon 1997). This program trains parent volunteers as “coteachers” to help classroom teachers facilitate learning in specific science units and also encourages parental participation in the school at all levels.
