RESEARCH ON EFFECTS OF INCREASING AGE LEVEL OF TEACHERS' POPULATION ON EDUCATIONAL ACTIVITIES

小学生问题行为的最新趋势表明，中小学生的数量在不断增加。然而，从教师群体的年龄水平增加与学生问题行为的关系角度来看，这一问题的实证证据很少。本项目的目的是阐明教师年龄水平的提高对教育活动的影响。我进行了四项问卷调查。第一份于1999年发放给8个县的1300名初中校长。第二笔是2000年向Oosaka、Hyougo和福冈县的1500名小学和初中校长发放的。第三个是2000年，给12个县的1300名高中校长。第四份于2001年发放给7个县的1300名小学校长。研究结果如下：(1)许多校长认识到学校教师年龄水平的提高对教育活动的影响。(2)教师的年龄结构对小学和初中教师应对学生问题行为的策略存在差异。(3)我们建议，根据教育权力下放政策的新方向，需要重新审视许多老教师在学校的学生指导能力。
