现代教育心理学和统计学研究表明,在课堂教学中,学生思维活动水平(s)并非一成不变,而是随着时间(t)延伸呈有规律的变化,如下图所示:这一曲线图形象地显示,在课堂45分钟内,学生思维水平随时间变化的基本规律。学生思维在课前10分钟内逐渐集中,在10~30分钟内处于最佳状态,接受能力最强,随后注意力逐渐下降。该变化规律对课堂教学具有重大指导意义,教师必须充分认识到学生思维状况与时间变化之间的规律,科学运用时
Modern educational psychology and statistical studies show that in the classroom teaching, students' thinking activity level (s) is not static, but changes regularly with time (t), as shown in the following figure: To show that in the classroom 45 minutes, the basic law of the level of thinking of students over time. Students' minds gradually converge within 10 minutes before the class, being in the best condition in 10 to 30 minutes, receiving the strongest ability and gradually decreasing in attention. The change rule is of great guiding significance to classroom teaching. Teachers must fully recognize the law between students' thinking status and time change. When using science,
