Through the third grade English teaching, I found that the interest in English is very important. We should enhance students’ interest in group cooperation and discussion. If the student is interested in English, he will take the initiative to learn English, often ask you in the exam, great enthusiasm for English. If there is no interest in learning English, students will have resistance, fear. Therefore, cooperative learning is very necessary for third graders or primary school students who are just beginning to learn English. It is not only the formal requirements of the new curriculum, but also should be implemented into teaching. This is especially important for English learning. Teachers must correctly divide students into groups to help students form a sense of cooperative learning. In this way, groups can learn from each other and help each other when students don’t know how to ask the teacher. As long as students are interested, whether it is lectures or activities, accept knowledge, students will be able to complete their studies faster and better.
