“一课三测”指的是课堂前测、课堂中测、课堂后测。从前测分析,优化设计;中测反馈,优化教学;后测延伸,培优辅差三个角度论述在一课三测的教学实践下,课前针对孩子已有的知识和技能等学情分析进行教学设计,课堂中针对孩子所出现的问题及时处理,课后进行延伸教学,确实能达到优化教学的目的。 “A lesson three test ” refers to the pre-test, test in the classroom, after-class test. From the perspectives of pre-test analysis, optimization design, mid-measurement feedback, optimization teaching, post-test extension and training and auxiliary training, under the teaching practice of one or three tests, we analyzed the existing knowledge and skills of the children before class, Conducting teaching design, timely handling of problems arising in the classroom for children, and extending teaching after class can indeed achieve the goal of optimizing teaching.
