The Impact of Challenge Quizzes on Student Knowledge
研究了一种混合形成性和总结性评估的挑战性测验工具，允许学生通过更难的测验提高成绩，从而激励调整学习行为并促进知识掌握，对教育工作者设计评估方式有参考价值。
We evaluate the efficacy of a blended formative/summative assessment tool developed to support mastery learning by students without placing undue burden on instructors. Our innovation provides students with an opportunity to take a more difficult “challenge” quiz to demonstrate their command of the material and improve their grade on regular in-class quizzes. The structure of these quizzes motivates students to modify study behaviors (formative component) and take responsibility for knowledge acquisition (summative component). This mastery-based testing approach serves to bring the student's objective of a quality grade in line with the instructor's objective of quality learning.
