Classroom instruction alone is not sufficient for solid learning. Students may have a Study Hall class that allows for additional academic support to students, where they can work on and receive assistance from their teacher and/or classmates on their projects and assignments. However, in addition to studying at school, home study is usually required each evening. Written assignments are only a minor phase of home study. Attention must be given to reviewing previous material and building needed skills. No student can say he/she has "no homework." The school day is too short to permit enough individual studying. Homework, therefore, is necessary in each course.
