教师在课堂上导入得合理、有趣,就能充分调动学生学习的积极性,学生们在课堂上就能很快就进入学习的状态,并始终保持良好的学习势头。反之,教师对于课堂的导入没有潜心研究,草率行事,不切合学生的实际,随意导入,就会严重影响学生的学习极积性。 Teachers in the classroom into a reasonable and interesting, it can fully mobilize the enthusiasm of students learning, students will be able to quickly enter the learning state in the classroom, and always maintain a good momentum of learning. On the contrary, the teachers did not devote themselves to the study of the introduction of the classroom, and did things in a sloppy manner that did not meet the needs of the students and were introduced at will. This would seriously affect students’ learning polarity.
