Having only one computer in a classroom presents challenges for teachers in ensuring all students receive equal computer time and practice technological skills. Key challenges include not enough time for each student to practice skills, inability for all students to see the computer at once, and determining what non-computer using students will do. Solutions involve using a projector to display the computer for all students to see, having students take turns using the computer for individual or group assignments, and designating the computer as a station for limited periods of time.
