At the same time, there are many courses in junior high schools, the task is heavy and the teaching hours are tight. If teachers use the traditional teaching model of unified teaching, the gap between the quick learners and the slow learners will be larger and larger. As for the students with more and more differences in learning demands, there must be some students to do independent thinking with less time and opportunity, while the other part of the students cannot meet the requirements and their learning initiative may be weakened. As a result, students’ learning attitude, learning ability, learning effects and other aspects of differentiation show more and more significance.

Chapter Two Literature Review
2.1 Definition of Relevant Concepts
2.1.1 Stratified Teaching
Today’s schools are in abundance of mixed-ability classrooms instead of classrooms with just high, average, or low. So, teachers must meet the immediate needs of all learners so they can progress successfully (Tomlinson, 2003). Students need to feel a sense of belonging and have teachers see them as individuals with individual needs. When this happens, and the curriculum is based on interest, teachers will increase motivation, productivity and achievement while meeting students’ needs (Tomlinson et al., 2003).
When it comes to the definition of Stratified Teaching, different researchers have different ideas.
Diane Heacox points out that Stratified Teaching is a teaching instruction based on the differentiation among learners in one regular classroom. Teachers grade students into several levels and adopt different teaching methods in accordance with learners’ competence. (Heacox, 2002) .
In class teaching, according to the requirements of the syllabus, according to the reality of each level of students, determine the teaching objectives of different levels, give different levels of tutoring, organize different levels of testing, so that all kinds of students can be interested in learning and get the fullest development.(Wang Xuming, 2002).
In order to improve the teaching efficiency, Deakin in his book indicates that teachers use students-centered teaching method and learners are required to achieve different learning goals because of differences in their learning abilities. (Deakin, 2006) .
