The study aims to comprehend the implementation of differentiated instruction strategies by the case junior high school mathematics teachers and the difficulties encountered, in addition to analyzing the influence factors in the implementation of differentiated instruction by case junior high school mathematics teachers. The study adopts case study method based on the characteristics of research theme and the research purpose, using observation, interview and document analysis for data collection in order to accomplish the research purpose. The research purpose is divided into four categories according to the aforementioned research motives: I. To understand the implementation of differentiated instruction strategy by case junior high school mathematics teachers. II. To discuss the implementation of differentiated instruction strategy by case junior high school mathematics teachers. III. To analyze the influence factors for case junior high school mathematics teachers implementing differentiated instruction. IV. Propose specific suggestions as reference for future educational administrative agencies, and junior high school and teachers implementing differentiated instruction. The study draws the following conclusion： I. Implementation of junior differentiated instruction by high school mathematics teachers. 1. Acquaint and control individual student difference using student data and tests. 2. Use supplementary teaching materials according to differentiated student level to meet the demand for student differentiation. 3. Guide student learning with questions and bring forward proper questions and classified teaching. 4. Achieve differentiated instruction through group discussions. 5. Adapt to students with different learning styles using teaching material based instruction. 6. Solve questions on the blackboard and instruct individual student with need using quizzes and practices. 7. Stimulate student thinking using the materials that interest the students. 8. Instruct student learning based on the instruction strategy of multiple solutions for one question. 9. Evaluate students using assignment grading. 10. Conduct differentiated evaluation using student test grading. 11. Accomplish differentiated instruction using correction, makeup tests and remedial instruction. II. Difficulties for case junior high school mathematics teachers implementing differentiated instruction 1. Distortion of intelligence tests and incompletion of student data lead to incapability to determine the true level of student differentiation. 2. Student learning cooperation and external environmental interference will affect the level of true student differentiation. 3. Big gap in student level prevents all units to implement differentiated instruction in teaching content. 4. Instruction progress prevents differentiated instruction for each class of instruction content. 5. The stress from general examination prevents differentiated instruction for each unit of teaching content. 6. Inability to take care of students of different levels and they will wait for each other. 7. Remedial instruction could not be implemented after class. 8. One instruction strategy could not apply to students of different learning styles at the same time. 9. Assignment and tests could not achieve true grading. 10. Many students could not attend the proficiency grouped instruction at the 8th class. 11. The level of question could not properly cooperate with the three levels of student capacity in A, B and C. 12. Not sufficient time to prepare tests for evaluating the three levels. III. The affecting factors of the case teachers implementing differentiated instruction. 1. The effects of math learning of the students are polarized. 2. The feedback of the students may influence the motivation of the teacher in implementing differentiated instruction. 3. The peer onion may affect the confidence of the teacher implementing differentiated instruction. 4. Not enough time for implementing differentiated instruction may affects the motivation of the teacher. 5. The extra work load of the teacher may occupy the time for differentiated instruction. 6. The family factors may influence the motivation of students in receiving differentiated instruction. 7. The students may feel frustrated and the motivation of receiving differentiated instruction may be reduced. 8. The promotion of differentiated instruction shall be based on the development of individualized teaching material. 9. Launch proficiency class for the 8th class to promote differentiated instruction. 10. Promote study on differentiated instruction through administration. 11. Comply with joint learning instruction demonstration to promote differentiated instruction. 12. The schools provide mathematics subject classroom to implement differentiated instruction. Base on the conclusions, the following suggestions are listed as reference for future educational administrative agencies, and junior high school and teachers implementing differentiated instruction. 1. To simplify the content for junior high school curriculum. 2. Provide proper disposal for students with low achievement from the last five percentile.
