新高考背景下,高中化学教学课时数与教学组织形式发生了一系列变化,随之而来的是一线教师在课堂教学和课后作业布置方面的深入思考。一种脱离“刷题”的纯手工校本作业形式使学生在原有知识和认知水平的基础上,主动发现知识间的联系,进一步提高了认识,为有效作业布置提供了新思路。 Under the background of the new college entrance examination, there has been a series of changes in the number of high school chemistry teaching hours and teaching organization, followed by the in-depth thinking of frontline teachers in classroom teaching and after-school homework assignments. A pure manual school-based operation mode that is free from “brush problems” enables students to actively discover the connections between knowledge on the basis of the original knowledge and cognitive level, and further raise the awareness, and provide new ideas for effective assignment.
