化学实验课程的信息化教学设计——以实验项目“水中化学需氧量COD的测定”为例

Design of Information Instruction in the Chemistry Laboratory Course: Taking the Determination of COD in Water as an Example

根据信息化教学的理念和特征,本文提出了信息化教学模式,并以实验项目"水中化学需氧量COD的测定"为案例,探讨该模式在化学实验教学中的运用,分析新模式对化学实验教学的影响。实践表明,在新教学模式下学生对该实验的掌握程度明显提高,大大缩短了实验时间,提高了教学效果。

This paper put forward a new design for information instruction teaching, based on the concept and characteristics of information instruction. Taking the determination of COD in water as an example,the complete instructional design scheme was constructed and implemented according to the new teaching model. The application of the new model was discussed, and the influence of information technology on the curriculum teaching was analyzed. The results suggested an improved master of the experiment and a shortened experimental time of the experimental implementation with the new teaching mode.
