从"路径依赖"到"另辟蹊径"--一道化学平衡变式练习的启示

“路径依赖”是新制度经济学中时髦的词汇 ,说的是人们一旦选择了某一制度 ,惯性的力量会使这一制度不断“自我强化 ,让你轻易走不出去”。“路径依赖”也是学生在解化学平衡题目时容易犯的毛病 ,这时我们需要学生“另辟蹊径” ,从而“峰回路转”找到一条快速准确解题的捷径。例 1　在一定温度下 ,向一容积固定的密闭真空容器中充入 2molX气体 ,发生反应X(g)Y (g) +Z(g) ,使反应达到平衡 ,这时容器中混合气体中X气体的体积分数是a %。若在同一容器中 ,最初放入的是 1molY和 1molZ的混合气体 ,并在相同的温度下使反应达到平衡 ,这时混合气…     

努力学习、研究、实践"全面的化学教育"理论--纪念戴安邦先生逝世5周年

UOOC平台与腾讯课堂相结合的“在线异步教学”

The COVID-19 broke out on a large scale, and online teaching became the first choice for teachers. Avoiding network congestion and ensuring learning effects are the dilemmas faced by online teaching. With the help of the UOOC platform and the Tencent Classroom, taking the "Polymer Structure and Performance" course as a sample, we suggested a new "online asynchronous teaching" model. Among them, the SPOC course is convenient for students to manage their learning time; "Chapter Quiz" and "Student-to-Student Mutual Evaluation" are helpful for students to obtain multi-angle feedback; project tasks are focused on case analysis so that students carry out inquiry-based learning. Overall, the "online asynchronous teaching" model breaks the time and space restrictions on teaching and learning, guarantees the quality of teaching during the epidemic, and lays the foundation for creating a "golden class".
