化学课是一门以实验为基础的科学,特别是近年来科学技术的飞速发展,实验内容的更替和新的实验手段的普遍应用,使它面貌焕然一新,特别是祖国“四个现代化”的要求,化学实验课从过去的验证、巩固、加深课堂教学的从属地位,逐渐发展成为一门独立的课程.它除继续担负原有的任务之外,着重通过实验培养学生的基本技能,实事求是的科学素养,认真探索的科学态度和独立工作的能力。多年来,由于我们对实验课的教学目的不够明确,加上实验条件较差,因而使实验教学 Chemistry class is an experiment-based science. Especially in recent years, the rapid development of science and technology, the replacement of experimental content and the universal application of new experimental methods have brought it a new look, especially the requirements of the “four modernizations” of the motherland From the past, verification, consolidation and deepening of the subordinate position of the classroom teaching, the chemistry experiment class has gradually developed into an independent curriculum which not only continues to assume original tasks, but also focuses on cultivating students’ basic skills and seeking truth from facts through experiments Literacy, a serious exploration of the scientific attitude and ability to work independently. Over the years, due to our lack of clarity on the purpose of experimental teaching and the poor experimental conditions, experimental teaching
