Abstract:

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.

Key words: Chemical laboratory course, Information instructional design, Case analysis
