古人云:“学贵多疑,小疑则小进,大疑则大进.”学生在化学的学习过程中,不能仅仅是被动的接受教师提出的问题,而应该主动的对所学的知识生疑.因为“疑则思,思则通.”只有经过自己的思考,进而找出问题的答案,学生才能真正的掌握知识.我们知道,化学是一门以实验为基础的科学,中学化学包含的重要内容是基础化学理论和基础元素化学.这些内容包含的知识点相对较为分散,有些内容甚至极为抽象、枯燥,于是有很多学生慢慢地失去了对化学学习的兴趣.心理学家研究发现,激发学生质疑可以使学生注意力集中,从而提高学习兴趣.正如教育家克莱·P·贝德福 The ancients said: “Students are more suspicious, small suspects are small and big suspects are big.” Students should not only passively accept questions from teachers, but should actively learn what they learned. Knowledge is skeptical. Because “thinking is thinking, thinking is pass.” Only through his own thinking, and then find out the answer to the problem, students can truly grasp the knowledge. We know that chemistry is an experiment-based science The important content of middle school chemistry is basic chemistry theory and elementary element chemistry. The knowledge contained in these contents is relatively scattered, and some contents are even extremely abstract and boring, so many students slowly lose interest in chemistry learning. Researchers have found that stimulating student questions can focus students’ attention and thus increase interest in learning. Just as the educator Clay P. Bedford
