With the globalization of information and business, people pay more and more attention to English reading. English reading, as one of the four skills of language learning, plays an important role in the English learning. In a sense, English reading, together with listening comprehension, speaking, and writing, is an important skill and holds a crucial status in learning the English language. Cooperative learning is a kind of teaching theory and strategy system based on group. The theory of cooperative learning which is applied in English reading class in senior high school and change the traditional teacher- centered teaching type. Cooperative learning as a breakthrough and complement against traditional classroom instruction is an efficient teaching approach, which can promote learner's cognitive ability and improve their competence to use language. This paper discusses how to apply the above mentioned theory to the learning practices in order to achieve better English reading and improve the reading achievement in college schools.展开更多

A qualitative case study method was used to understand the GI system used by Chinese instructors as well as the achievements acquired and challenges met by the participants. Three instructors and fifteen second-year-undergraduates taking a course titled Sources of European Culture participated. Interviews, observations, and documents were used to collect the data. Data analysis showed Chinese instructors applied a GI technique similar to that discussed by Johnson and Johnson(1999); however, GI in the Chinese context demanded more effort from the teacher for designing tasks and provided help in modeling uses of English and in preparing visual, especially Power Point, presentations. Although participants used their mother tongue at some stages, their autonomy over English learning was activated, and horizons in the course content were broadened.展开更多
