当前学校的课堂教学面对一个普遍存在的问题,学生的知识基础和学习能力存在一定的差异性,导致课堂上出现“优生食不饱,后进生学不到”的情况。断层现象导致教师难以顾及两头,经常出现教学滞后的情况。笔者近年来在科学课堂教学中,对信息技术支持下的“翻转课堂”模式进行教学探索,把“填鸭”式课堂转变为学生自己知识内化、互动答疑、小组合作交流讨论、做作业的自主课堂。 At present, classroom teaching in schools faces a ubiquitous problem. There is a certain difference in students’ knowledge base and learning abilities, which leads to the emergence of “eugenics insufficiency, backward learning” in the classroom. The fault phenomenon makes it difficult for teachers to take both ends into consideration, and often lags in teaching. In recent years, in the teaching of science, the author tries to probe into the teaching mode of “flip classroom” under the support of information technology, and transform the “duck ” classroom into the students’ own knowledge internalization, interaction and answering, Homework-independent classroom.
