一堂高质量的化学课有了良好的开端 ,充实的过程 ,在结尾时还应为它画上点睛之笔。俗话说“编筐编篓 ,重在收口 ;描龙描凤 ,重在点睛”,说的就是这结尾的作用。精心设计每节课的结尾 ,养成学生良好的思维习惯 ,让学生保持浓厚的学习兴趣 ,对提高教学质量的确起着重要的作用。初 A high-quality chemistry class has a good beginning, a substantial process, and it should be crowned with a finishing touch at the end. As the saying goes, “The compilation of baskets is very important, and the emphasis is on shutting down; depicting dragons and tracing phoenixes and focusing on the dotting of the eyes.” This is the role of this ending. Carefully designing the end of each lesson, develop students’ good thinking habits, allow students to maintain a strong interest in learning, and indeed play an important role in improving the quality of teaching. early
