【Abstract】Corrective feedback（CF）， as an important form in the interaction process， is the key to stimulate negotiated interaction to promote the second language development. The study adopts a pretest-treatment-posttest design with 30 senior high students as participants， whichpresents an in-depth analysis of CFin English speaking classrooms for senior high students in China. The key issue is whether CF differs quantitatively and qualitatively in different combinations in the aspects of their frequency， their outcomes and their effects.

1. Introduction
The Interaction Hypothesisstates that the development of language proficiencyis promoted by face-to-face interaction and communication. To answer the question how students can best be assisted viaclassroom interactions in becoming more target-like language， I sought to show how corrective feedback （CF）provided during negotiated interactionshapes interlanguagedevelopment.
2. Literature Review
There was a great body of study related to CF， butproblemsarose when adapted to the teaching and learning environment in China.So，， this study explores theiroccurringin student-student interaction in English speaking classroom， which is hoped to find a more effective and practical way of administering CF.
3. Research Design
3.1 Research Questions
In this study， I explore several questions related to CF：
（1） How frequent is CF in Groups？
（2）Dose CFdiffer qualitatively and quantitatively in different combination of interactions involving different proficiency levelsofstudents？
（3）Can CF promote students’speaking competence development？
3.2 Participants
The participants are30 students with different proficiency levels， low， middle and high English， who are senior high students. They form groups， combinations and dyads.
4. Results and Data Analysis
4.1 Data Summary of CF in Groups
Table 4.1 showed that five CF strategies were used by students， explicit correction， recast， clarification requests， elicitation and repetition. Among them， recast and clarification request were the two most frequently used （at rate 39.5% and 31.5% respectively） and metalinguistic feedback had not been used.
