将前沿科研成果融入到大学生创新实验项目教学中,进行了以"聚羧酸减水剂的制备及其对水泥流动度的影响"为案例的综合性创新实验教学设计安排.首先让学生学会化学反应机理和聚合物的分散作用机理,然后让学生制备聚羧酸减水剂,并对减水剂对水泥的流动度性能的影响进行测试,进一步探索出采用不同用量丙烯酸和过硫酸钾制备的聚羧酸减水剂对水泥流动度的影响变化规律,增强了实验的创新性、高阶性和趣味性.本课程注重以学生发展为中心,将BOPPPS教学模式引入教学过程中,不仅可以扩展学生的知识面、锻炼实验操作技能,还能提升学生发现问题、分析问题和解决问题的能力.
Integrating Frontier Research Achievements into the Innovative Experimental Program Teaching of Undergraduates—Take the Preparation of Polycarboxylate Ether Superplasticizer and Effects on Cement Fluidity as an Example
To integrate the frontier scientific research results into the innovative experimental project teaching of college stu-dents,a comprehensive innovative experimental teaching design arrangement was conducted with the case of"preparation of poly-carboxylate ether superplasticizer and its effect on the flowability of cement".Firstly,students were taught the chemical reaction mechanism and the dispersing mechanism of polymers.Then,students were guided to prepare polycarboxylate ether superplasticizer and test its influence on the flowability of cement.Furthermore,the variation pattern of the impact of polycarboxylate ether super-plasticizer prepared with different dosages of acrylic acid and potassium persulfate on the flowability of cement was explored,en-hancing the innovation,advanced level,and interest of the experiment.This course focuses on student-centered development and in-troduces the BOPPPS teaching model into the teaching process,which not only expands the students'knowledge and practical skills but also improves their ability to identify,analyze,and solve problems.
