A language plays an important role of consequence in creating the spirit of the native nation which grown up by emplying it as a vernacular. The structure of a language - whether it is that of sound, or that of words, or that of grammar - is planted in the world of notion of each people who use the language as their mother tongue, vernacular. Whereas, this world of notion rarely changes throughout one`s lifetime. This is what generating the wpiritual world of each nation`s people. Consequently, It can be said that mankind can be albe to become a `sane human beings` by means of a language. In view of such statement, the job of enhancing their vocabulary ability during childhood period is a very rewarding task to let them not only learn their vernacular language, but also consolidate the spiritual world of their native people in their minds. Through this thesis, I exerted myself to guide, and to increase the vocabulary ability of children by presenting an integrated language program via nursery rhymes. The analysis result of the vocabulary ability classified by the gender of male and female shows that the male of experiment has witnessed the increase of +1.69 while the female of experiment has that of +3.58, from which we could see the vocabulary ability for female has greatly increased. During instructing the entire process of the integrated language program, I could discover female children behave more actively and participate more positively than male counterpart. The analysis result of the vocabulary ability classified by the ages of full 4-year-olds and full 5-year-olds is presenting that the full 5-year-olds of the experiment has improved by +3.27 while the full 4-year-olds did by +2.00, from which we could find that the vocabulary ability of the full 5-year-olds has improved greatly. Even there is only one year difference in these two groups, we could see that the more effective period for receiving the integrated language program is the full 5-year-olds, which is the age of just right before entering the primary school. The analysis result of the commanding vocabularies and the entire vocabulary ability of the language expression employed by two groups, experiment group and a controlled one, is presenting that the experiment group has shown a great difference of +5.27 by shifting the average of 20.47 at pre test to 25.74 at post test. I could confirm that the integrated language program plays an important role in increasing vocabulary ability of children.
