在物理教学中,第一印象的建立特别重要。第一次接触到的模型,第一次听到的比喻,第一次观察到的现象,第一次动手做的实验等等,它们对学生的印象特别深,震动也特别大。因此教师在讲授物理实验、例题分析、模型演示时,都应特别重视第一印象的建立。要千方百计做到生动、形象、准确无误,这样可以减少“思维定势”的消极影响,使新的信息对大脑产生强有力的刺激,让学生建立起准确而鲜明的第一印象。这样,学生对所学的知识就能理解得深,记忆得牢,应用得活。
In physics teaching, the establishment of a first impression is particularly important. The first contact with the model, the analogy I heard for the first time, the first observed phenomenon, the first hands-on experiment, etc. They have a particularly deep impression on the students and a great shock. Therefore, teachers should pay special attention to the establishment of the first impression when teaching physics experiments, sample analysis, and model presentation. We must do everything possible to make it vivid, visual, and accurate so that we can reduce the negative influence of “thinking and setting”, make new information powerfully stimulate the brain, and allow students to establish accurate and distinctive first impressions. In this way, students can understand the knowledge they have learned deeply, have a good memory and use their lives.
