中学化学课程标准,明确指出了高中阶段化学的“课程性质”探究性:在教学中设计以实验为主的科学探究活动,能激发学生对化学学习的兴趣,引领学生在观察、实验和交流讨论中学习化学知识,提高学生的化学探究能力.在上教版的修订后的教科书中“活动与探究”共有47个左右,其中多数涉及了实验,这些实验大多数其实为验证性实验,探究的成分不够,或者对相关现象的本质没有进行进一步的探讨.笔者认为利用对比 High school chemistry curriculum standards, clearly pointed out that the high school chemistry “curriculum nature ” Inquiry: In the teaching of experimental design-based scientific inquiry activities, can stimulate students interest in chemical learning, leading students in observation, experiment and Exchange of discussions to learn chemical knowledge and improve students’ ability to explore chemistry.In the revised version of the textbook, “activities and inquiry” a total of 47 or so, most of them involved in the experiment, most of these experiments are actually verifiable Experiment, explore the composition is not enough, or the nature of the phenomenon did not carry out further discussion of the author that the use of contrast
