The purpose of this study was to compare enhancement of disirable characteristics between pre-school children through playing with commitment and interaction in the playing corner. Thirty of five-six year old pre-school children of the school semester in the 1995 adacemic year of Wat Yayrom School (Watanarachrungsun), Jomtong Bangkok were randomly selected as the samples, and assigned equally into 2 experimental groups. The first group was provided commitment playing and the other was provided interaction playing in the playing corner. The experiment was carried 8 weeks. The study was randomized control-group pretest-posttest design. Research instruments developed by the researcher, include a lesson plan, and desirable characteristics observation guideline. The score of enhancement of disirable charactieristics between the groups were compared using t-test. The finding revealed that : 1. desirable characteristics of the two groups after experiment were significantly higher than before at .01 level. 2. desirable characteristics of the group provided commitment playing was better than interaction playing group at .05 level of statisfical significance 3. tolerance of desirable characteristics of the two groups decreased significantly at .01 level. 4. tolerance of desirable characteristics of the group provided commitment playing was better than interaction playing group at .05 level of statisfical significance.
