化学学习和实验不可分割,在课堂中开展实验可以让教学更具时效性,让学生在参与的过程中亲身感受到知识的生成过程,进而切实把握和深刻理解知识点.目前,高中化学实验课时常会遇到设备缺失和实验污染性高的问题.因此,围绕教材中的实验对某些实验装置进行改良,或者是改用微型实验装置,这便成为了化学实验课的首选. Chemistry learning and experiment can not be separated, to carry out experiments in the classroom can make teaching more time-sensitive, allowing students to personally experience the process of knowledge generation in the process of participation, and then effectively grasp and deeply understand the knowledge point.At present, the high school chemistry experiment class Often encountered the problem of lack of equipment and high experimental pollution.Therefore, some experimental devices around the experiment in the textbook to improve, or switch to micro-experimental device, which became the first choice of chemical experiment class.
