新课程改革背景下,追求“双有效”教学目标,必要的作业训练不仅可以巩固课堂所学内容,更能有效地提高学生分析问题、解决问题的能力。那么作为教师,如何精选练习?通过认真批改后,又如何评讲练习呢?通过多年的教学实践,对新课程背景下的化学习题教学有一些想法。 In the context of the new curriculum reform, in pursuit of the “double effective” teaching goal, the necessary homework training can not only consolidate the content learned in the classroom, but also effectively improve students’ ability to analyze and solve problems.
