我国大学英语教育受教育资源缺乏的限制,多采用大班课堂进行教学。因此,课堂互动环节和英语语言环境的相对缺乏不能调动学生的学习积极性,造成了学生的口语表达能力比较差的现状。要在现有的大班课堂教学模式下提高学生的口语能力就要更新课堂教学观念,科学设计教学形式和内容,激发学生的学习动机,从而弥补课堂教学的不足。 The college English education in our country is limited by the lack of educational resources, and more classes are used to teach in large classes. Therefore, the relative lack of interaction in the classroom and the English language environment can not arouse students ’enthusiasm for learning, resulting in a relatively poor performance of students’ oral communication skills. In order to improve students’ oral ability under the existing teaching mode of big class classroom, it is necessary to update the concept of classroom teaching, design the teaching forms and contents scientifically, and stimulate their motivation to make up for the deficiency of classroom teaching.
