The Graded College English Teaching Guided By The Theory Of "i+1"

Recently with the increased college enrollment, there are greater individual differences among students, but our current material is not suitable for all the levels of the students and the teaching method can not apply to all the students, so graded teaching tends to be carried out as a reform of college English teaching. It reflects the principle of "Teaching According to Students' Levels'" which is the main characteristic of College English Teaching Syllabus."i+1" theory is the essence of the Input hypothesis put forward by American linguist Krashen in the SLA. "i" represents the learner's current level; "1" refers to the language a little beyond the learner's current level. Only when we fully understand the omprehensive input (i+1) according to a natural order can we transit from "i" to "i+1". Meanwhile, we need some affective factors to take in the input, i.e. strong motivation, great confidence and low anxiety, to come by real acquisition.This paper attempts to combine the "i+1" theory and the Graded College English Teaching (GCET). The theory is the most important theoretical basis of the teaching. Through the research design of graded teaching, focusing on the preparation, construction of the model and data analysis, it turns out that "i+l"theory makes a great sonse to the GCET and makes a great difference to the college English teaching.. The experiment was conducted in two parts: 370 students from the Department of Economy And Trading and 186 students from the Medical Department in Grade 2002 comprised Experimental Group One and Controlled Group One. And 9 departments of 2161 students of Grade 2002 who received graded teaching comprised Experimental Group Two and another 1962 students of Grade 2001 who received traditional teaching comprised Controlled Group Two, so data was obtained and analyzed through horizontal and vertical comparison. And the questionnaire and verbal report provided additional data. The results showed that the GCET helped students improve their English level as well as their views towards foreign language learning.
