新课改下,教师要发挥出学生的主体地位,增强师生、生生之间的交互活动。在教学中运用好小组合作学习可以使我们的教学达到事半功倍的效果。在高中化学教学中,教师不仅要教给学生合作的有效方法,并且要注意问题的设计,同时教师要发挥好自己的作用,对学生做出积极的评价。 Under the new curriculum reform, teachers should give play to the student’s dominant position and enhance the interaction between teachers, students and students. Using well-coordinated group learning in teaching can make our teaching more effective. In high school chemistry teaching, teachers must not only teach students effective methods of cooperation, but also pay attention to the design of problems. At the same time, teachers should play their role and make positive evaluations of students.
