化学实验以其生动、有趣、直观的特点深受学生喜爱。作为新课改一线的实验教师,就应潜心开发课程资源,尽可能多地补充一些教科书上不要求做的实验,这不仅有利于培养学生实事求是、科学认真的学习态度,也有利于增强学生探索知识的积极性和激发学生学习化学的兴趣,具有非常重要的现实意义。 Chemical experiments are popular with students for their vivid, interesting and intuitive features. As the experimental teacher of the new curriculum reform, it is necessary to develop the curriculum resources with utmost care and to supplement as much as possible the experiments that are not required in the textbooks. This will not only help foster students’ attitudes towards seeking truth from facts, but also help strengthen students’ exploration. The enthusiasm of knowledge and the stimulation of students’ interest in learning chemistry are of great practical significance.
