苏霍姆林斯基曾经说过:“教学的技巧并不在于预见得到的所有细节,而在于根据当时的具体判断,巧妙地在学生的不知不觉中做出相应的变动。”教师虽然在备课时做了周密的预设,但由于每个学生认知方式、知识储备和学习能力的不同,在教学中难免会有学生打破教师精心的预设,创造“意外惊喜”的现象出现。在教学过程中,教师要不断捕捉、判断和重组从学生那里涌现出来的各类信息,把突发的和意外的资源转化为有价值的课堂教学资源。本文就化学学科中最易出现意外的几个教学环节来阐述如何巧妙地将意外资源为己所用,让课堂回归本真。
Sukhomlinski once said: “The teaching technique does not lie in all the details that are foreseen, but in skillfully making corresponding changes in the students’ unconsciousness according to the specific judgments of that time.” “Teachers Although careful preparation is made during class preparation, students will inevitably break the teacher’s meticulous precepts and create ”unexpected surprises" due to the different cognitive styles, knowledge reserves and learning abilities of students. Phenomenon appears. In the process of teaching, teachers should constantly capture, judge and reorganize all kinds of information emerging from students and turn unexpected and unexpected resources into valuable classroom teaching resources. In this paper, the most prone to accidents in the chemical discipline of several teaching links to elaborate how clever use of accidental resources for their own, so that the classroom return to true.
