The benefit of Case Method of Teaching is to combine living experience and offering students an opportunity to discuss and think through the process of case studying. Comparing to traditional method, it can contribute to more interact between teachers and students, therefore achieving overall better learning experience. However, to utilizing a higher level of effectiveness and overcoming its limitations, teachers must use 3 strategies: sufficient preparation prior to class, follow-up evaluations for both in and after classes. Cases adopted in No. 535 Interpretation are effective, localized, referable, and close to daily lives. By choosing it students can not only easily combine their visitation experience through the interactive process with law-enforcement authorities, having better understanding to the importance of human rights, they can also relate their living experience to the constitutional contents and judge interpretations, therefore a deeper thinking to why the judge reveal a proportional principal in No.535 Interpretation. For the teaching strategy in this case: teachers should team up students prior to the class one week earlier, handing out reading materials and giving notes to the discussion topics. When the class begins, they should conduct case studies and review to the case itself. The discussion process is a good opportunity to clarify students' ideas of human rights and rule-by-law principles. After the class, we suggest teachers to adopt multiple evaluation methods. For instance, evaluating students' participations in discussion and their performance, asking them to write reports or conduct a written test to better understand the levels of understanding to the teaching materials.
