以545名中学生为调查对象,对中学生控制变量能力的现状进行调查。结果表明:(1)中学生控制变量能力随着年级的增长呈现不断提高的趋势;(2)男生在高中阶段单变量控制能力呈现高位振荡,而女生在初中阶段多变量控制能力呈现低位振荡;(3)男生的多变量控制能力呈现平稳发展态势,女生的单变量控制能力呈现平稳发展态势;(4)在高三阶段男、女被试在单变量控制能力方面呈及其显著性差异,其它阶段无显著性差异。
A survey of 545 middle school students was conducted to investigate the current status of middle school students’ ability to control variables. The results showed that: (1) The ability of middle school students to control variables showed an increasing trend with the increase of grades; (2) The univariate control ability of high school boys showed a high level of oscillation in high school, while girls showed a low level of multi-variable control in junior high school. 3) The multi-variable control ability of boys shows a steady development trend, and the univariate control ability of girls shows a steady development trend; (4) There is a significant difference in the control ability of single-variables between male and female subjects in the third stage of senior high school.
