化学实验是中学化学教学中最普遍采用的媒体。由于实验条件的限制,实验的科学性、直观性、探索性和操作性的特点在教学中未能真正体现。使现有的实验不能完全地发挥其教学作用。因此,把现代信息教学技术应用于化学实验教学中,克服实验条件的限制,旨在对以下几方面有所突破,提高演示实验的可见度性。增加演示实验的时效性,保障演示实验的安全性,加强学生实验操作的规范性,为创造学生进行实验设计的条件,丰富学生实验知识等,以期最大限度地发挥实验的作用。
Chemistry experiments are the most commonly used media in secondary chemistry teaching. Due to the limitations of experimental conditions, the scientific, intuitive, exploratory and operational characteristics of the experiment can not be truly reflected in the teaching. So that the existing experiment can not fully play its teaching role. Therefore, the application of modern information technology in chemistry experiment teaching overcomes the limitations of experimental conditions and aims to make breakthroughs in the following aspects and improve the visibility of demonstration experiments. Increase the timeliness of demonstration experiments, guarantee the safety of demonstration experiments, strengthen the standardization of experimental operation of students, create conditions for experimental design for students, and enrich students’ experimental knowledge so as to maximize the experimental effect.
