| 摘 要： | 尽管控制变量法对某些多因素问题失效,但当前探究教学中几乎压倒性地用控制变量法来研究多因素问题,此项研究调查了这种做法对中学生探究方案设计所造成的影响,结果表明:在具有简单多因素实验设计的意识和能力的学生中,初一学生的比例大于初二、初三和高一学生的比例,这说明过度的控制变量法训练,削弱了多因素实验设计的意识和能力,窄化了学生探究方案的设计思路.

| Abstract: | Although the variable-control method becomes invalid to certain multifactor,current teaching inquiry is largely using of variable-control method in study of the multifactor.This research investigates the impacts of the inquiring method on middle-school students.The study indicates that among the students,who are conscious of and have the ability to the simple design of the multifactor experiment,the freshmen have a better percentage and there is more number of proportions than those of sophomores and juniors of junior high,as well as the freshmen of high school.This signifies that the excessive training of the variable-control method weakened the consciousness and the capability of the designs of multifactor experiment.It also narrowed the designing mentality of inquiring plan. |
