Learning efficiency is an important issue to modern education. So constructing a self-evaluation mechanism to a teaching department is an urgent issue in order to improve teaching quality, promote teaching efficiency and students' learning effect. It is a normal method to understand the students' learning effect of Chinese literature for freshman via unified examination. In this study, the relative quantificational data of Chinese literature teaching efficiency for freshmen was analyzed at the respect of productivity. An objective performance self-evaluation model was constructed to evaluate its performances and it can be used at relative departments in university. Data Envelopment Analysis (DEA) method was used to investigate the teaching efficiency of every evaluated unit. The input variables come from the teaching topics of reading and writing and input resources for unified examination. The output variables come from the student's learning effect. All of them were defined by five teachers who are teaching this course at present. The author's affiliation in central part of Taiwan was taken as an example to demonstrate the proposed model working. The performance index and model can provide the information to relative departments at university. The evaluation results also can provide the strategy and direction of teaching improving to promote the students' learning effect.
