初中化学教学中学生对于开发性题目存在着明显的畏难情绪,对于这种类型题目的解答方法也存在着很大的困惑,这并不是因为学生对化学基础知识的掌握不够牢固,也不是因为学生的能力水平较低,而是因为学生在长期的机械重复练习以及固化封闭题型的训练之下,其思维模式也变得比较封闭,对开放性试题的探究意识大大减弱,所以,在面对这些试题时感觉无所适从。在素质教育的背景下,必须要强化开放性试题的设计,并将其运用到教学实践中。 Middle school chemistry teaching middle school students for developing the subject there is a clear fear of emotions for this type of problem solving methods there are also a lot of confusion, not because students grasp the basic chemical knowledge is not strong enough, nor because students But because of their long-term mechanical repetition of practice and the curing of closed-type questions under the training of its mode of thinking has also become more closed, the exploration of open questions to explore awareness greatly reduced, so in the face of these Test questions feel confused. In the context of quality education, we must strengthen the design of open questions and apply it to teaching practice.
