根据现代教育心理学的统计和测定,学生在课堂教学活动中,思维集中程度 S 与时间 t 的变化关系,可用如图1所示的曲线来表示。本曲线表明:在课堂教学开始的 t_0——t_1(这段时间称为 T_1)这10分钟内,学生的思维逐渐集中,在 t_1——t_2(T_2)这20分钟内,思维处于最佳活动状态;随后(T_3),思维的集中程度逐渐下降,接受知识的能力也随之下降。尽管这一曲线是在一定条件下得
According to the statistics and determination of modern educational psychology, students in the classroom teaching activities, the level of concentration of thinking S and time t changes, the relationship shown in Figure 1 can be used to represent the curve. The curve shows that during the first 10 minutes of t_0 - t_1 (T_1 is called in this period), the thinking of students gradually concentrates. During the 20 minutes of t_1 - t_2 (T_2), thinking is in the best activity State; then (T_3), the concentration of thinking gradually decreased, the ability to accept knowledge also will decline. Although this curve is in certain conditions
