“反复教学法”是一种通过把知识从视觉和听觉上重复出现在学生的眼前和耳边,以达到提高学生学习水平的教学方法。文章根据人类的记忆规律与遗忘曲线,依据混泥土结构设计原理课程的特点,设计了一个教学与考核的实验,通过多次的实验,实验结果显示:“反复”的次数与记忆水平线先是呈正相关,当知识的积累量达到一定程度后,学生对知识的记忆能力提高不明显。 “Repetitive Teaching Method ” is a teaching method that improves students ’learning level by repeatedly presenting knowledge in the eyes of students and students’ ears visually and aurally. According to the memory rules and forgetting curves of human beings, according to the characteristics of concrete structure design principles curriculum, this paper designs a teaching and assessment experiment. Through several experiments, the experimental results show that the number of “repeated” and the memory level first Was positive correlation, when the accumulated amount of knowledge reached a certain level, students’ memory ability of knowledge is not obvious.
