Effect of precalculus revision on improving students' performance in a Calculus I course

摘要

This action research investigated whether quick and detail revision of precalculus material had an effect on students' academic performance in a Calculus 1 course. Quizzes, online homework, questionnaire, and interviews are used to provide evidence that precalculus revision had positive impact on students' performance. The findings are consistent with other research studies that in the literature. As a result of this research, I plan to do a precalulus revision in hopes that it will have a positive effect on student's academic performance in the future.
