最近听了一节课 ,课题是“一元一次方程的应用 (工程问题 )” ,教师课前布置了预习作业 ,这个预习作业将课本中的一道例题进行了很细的分解 ,给出的填空档有 15个之多 .课上分析时又一一提问 ,对每个问题 ,学生们都齐刷刷地举手 ,准确地回答 .表面上看 ,教师给学生提出了不少的 Recently I had a lesson and the subject was “Application of one-dimensional equation (engineering problem)”. The teacher pre-arranged the preparatory assignments. This preparatory assignment took a very detailed breakdown of the examples in the textbook and gave the blanks. There are more than 15 questions. During class analysis, another question is asked. For each question, the students are all raising their hands and answering accurately. On the surface, teachers give students a lot of questions.
