高中化学原理内容是教学的难点,主要原因是原理内容抽象,不好理解,因此,帮助学生建立直观正确而深刻的第一印象就更为重要。沉锚效应就是利用先入为主的观念,让学生产生第一印象,帮助学生学习。以化学平衡移动原理与盐类水解的教学为例,具体讨论沉锚效应在教学中的应用。 The content of high school chemistry principle is the difficulty of teaching. The main reason is that the principle content is abstract and not easy to understand. Therefore, it is more important to help students establish an intuitive, correct and profound first impression. The anchoring effect is to use preconceived ideas to give students a first impression and help them learn. Taking the teaching of chemical equilibrium movement and salt hydrolysis as an example, the application of anchor anchor effect in teaching is discussed in detail.
