做中学对中学生生物学问题表征的影响

Effective of Hands-on Representation of Biological Problem of Middle School Students

选用中学生物学中有关探究性实验的、与"动手"密切相关的三个开放性问题,对高中和初中学生进行测试,分析被试进行问题表征的环节与结果,探讨"做中学"对学生问题表征的影响.结果显示,在解决实际问题的过程中,学生有无"做"的经验,的确影响问题的表征.

Three open-ended biological questions at middle school level which relate to the inquiry experiment and hands-on activity was selected to examine the situation of problem representation of senior or junior middle school students, and to seek if the process of problem representation is affected by handson activity. The results showed that in the process to resolve actual problems, problem representation was influenced by students experience of hands-on learning.
