With the push of courses of the nine-year system at the last two year of elementary school, the understanding of courses' practice becomes a crucial key to the reformation of courses. There are much research and essays on courses of the nine-year system. There are much more discussion of theories than the substantial information. The study taking Tainan City as an example with the highest rate of carrying out the nine-year system in Taiwan area, sets to the analyses of substantial information, which related to teaches' attitude towards the nine-year system in the past year. Besides, we can further understand present situations and problems of courses of the nine-year system. Through the tests of difference of average and regression analyses, the study can reach several important conclusions: First, teachers at middle and elementary schools have expressed many different viewpoints on curriculum of the nine-year system. In my study, ten questions on the nine-year system are negative answers among twelve questions. Teachers' attitude, however, is mostly positive towards the cooperation and spirit of the nine-year system. The directors but none at middle and elementary schools have the highest degree of cooperation on curriculum of the nine-year system. Second, teachers' most worry thing is the ability insufficience of courses' design and the difficulties of developing school curriculum in ability indictor. Those teachers whose educational background is low will show their anxiety. Third, the recognition of female teachers on curriculum of the nine-year system is far above male teachers'. When teachers are more younger, they will have preparation on curriculum of the nine-year system.
