作业批改作为常规教学的重要环节,既是课堂教学的补充和延伸,也是学生对所学知识消化、吸收乃至进一步升华所必需的手段,也是教学信息反馈的重要途径,共同达到教学相长。但现实情况是作业教学不能与课堂教学改革同步进行,成为薄弱环节,影响了整个化学教学质量的提高。 As an important part of regular teaching, homework correction is both a supplement and an extension of classroom teaching. It is also a necessary means for students to digest, absorb, and even further sublimate the knowledge they have learned. It is also an important way for feedback on teaching information and achieves a combination of teaching expertise. However, the reality is that homework can not be synchronized with classroom teaching reform, and it becomes a weak link, which affects the improvement of the overall quality of chemistry education.
