Vern Williams, a middle school math teacher, believes that the topic of lengthening school days has certain benefits depending on what the extra time will be used for. He agrees that lengthening the school day would be worth it if the added time were to the core classes, but that it wouldn't be of any use if such time were added to help prepare students for state testing because it wouldn't be anything better than a "glorified recess or unstructured study hall." He also goes on to mention that the factors of if homework load as well as teaching duties will be lowered or not due to the extra time being spent at school.
