俗话说:“实践是检验真理的唯一标准。”在化学知识的学习中,大部分理论性知识都需要实验来验证,所以实验是化学教学的重要部分。几年来,随着新课程改革的进行,素质教育的全面铺开,教学方式、方法、模式不断推陈出新,其中实验教学也有了很大的改进。但是,在实际教学中,仍然存在一些问题。例如,教师还是习惯性地讲知识、讲实验,比较形象的就是放PPT,远观的演示实验多于边讲边做及亲自动手的学生实验,结果造成学生对相关化学知识的学习只知其然而不知其所以然, As the saying goes: “Practice is the sole criterion for testing truth.” In the study of chemical knowledge, most of the theoretical knowledge requires experimentation to verify that experiments are an important part of chemistry teaching. In recent years, with the progress of the new curriculum reform and the full development of quality education, teaching methods, methods and models have been continuously introduced. Experimental teaching has also been greatly improved. However, in actual teaching, there are still some problems. For example, teachers are still habitually speaking of knowledge, speaking of experiments, comparing images to put PPT, far more demonstration experiments than talking and doing so and hands-on student experiments, resulting in students learning about the relevant chemical knowledge only However, I do not know why,
