The main purpose of people learning language is to communicate; listening and speaking are essential language abilities. Referring to the National educational policy, the teaching of the Taiwan southern Min dialect is also encouraged to focus on enabling good communication which is based on listening and speaking abilities. The Content-Based Instruction (CBI) stated that people should apply the language as a tool to gain meaningful knowledge, instead of learning the language itself. In this thesis, the research of applying CBI teaching approach on Taiwan southern Min dialect language classes is studied. In this research, the objective students are fourth grade in an elementary school located in Hsinchu City, Taiwan. The courses are designed based on the Curriculum Guidelines of 12-Year Basic Education, and the CBI Theme-based model is adopted in which the Six T’s approach is referred as for teaching design and the Standard-Based Assessment of Student Achievement (SBASA), to understand the language learning process and effectiveness of students. In this research, the CBI teaching approach is applied in the Taiwan southern Min dialect class. Some findings are summarized as follow. The picture books build a good scenario for students making more comprehensive connection between the knowledge contents and the target language. The interesting scenario would raise the student’s learning motivation as there are some interesting topics (insects) or daily life experiences, which let students actively learn and communicate with using the target language. The assessment of the student learning, based on SBASA, helps teachers not only to understand the student’s learning status, but also to each student’s advantages, specific reactions during learning process and difficulties or challenges. In the end of the experimental language class of applying CBI teaching approach, most students achieved the grade level of “B-Good” and qualified. The results show that applying CBI teaching approach on Taiwanese language class, it is helpful to students leaning and their language abilities could achieve an expected level.
