无机及分析化学“矛盾”现状及“渗透式”教学改革——融合光敏有机硅树脂紫外光固化程度的定性与定量分析实验

“Contradiction” Status and “Permeable” Teaching Reform of Inorganic and Analytical Chemistry——Fusion of UV-Curing Degree Qualitative and Quantitative Analysis Experiment of Photosensitive Silicone Resin

《无机及分析化学》是食品、农学、环境科学等专业学生必修的一门基础课。师生普遍反映该课程内容多、难度高、课时较少,教学效果不理想,学科平均成绩偏低。结合课程特点与教学培养目标,本文对课程教学体系提出了“渗透式”教学改革方案,包括教学内容优化、激发学习主动性和兴趣、落实学生主体地位、教学考核方式优化及理论与实验有效结合等内容,以达到提高学生自主学习能力、增强教学效果的目的。融合光敏树脂光固化反应程度的定性与定量分析实验,使学生熟悉光敏树脂体系光固化程度的评估手段,并掌握仪器设备的使用,提升学生的科学素养。

Inorganic and analytical chemistry is a kind of basic courses for students of food, agronomy and environmental science. However, teachers and students generally report that the course has a lot of content, high difficulty, less class hours, unsatisfactory teaching effect, and low average grades in the subject.Combined with the course characteristics and teaching training objectives, a “penetration-type” teaching reform program was proposed in this paper, including teaching content, stimulating learning initiative and interest, implementing students’ dominant position, teaching assessment methods and combination of theory and experiment, so as to promote students’ autonomous learning ability and enhance teaching effect. Integrating qualitative and quantitative analysis experiments on the UV-curing degree of the photosensitive resins, students are familiar with the evaluation methods of UV-curing degree of photosensitive resin systems, and master the use of instruments and equipment in order to improve students’ scientific literacy.
