ABSTRACT The primary goal of this study is to examine the reason of conflict between the administrative personnel and the teachers¡¦association; and the relationship among the modes of conflictive management, the reason of conflict, and the strategy of conflictive management. Firstly, the relevant literatures concerning the reason of conflict and the strategy of conflictive management at the schools were collected, reviewed, and analyzed. Secondly, the procedure of the study was presented and a questionnaire was designed. A pilot study was conducted and then the questionnaire was developeded. The subjects included 778 administrative personnel chosen from 51 public elementary schools through stratified random sampling. In this study, 644 copies of questionnaire were collected, and the total valid copies were 600. The percentage of questionnaire was as high as 85.7%. Following that, the statistic methods including descriptive analyses, t-test, one-way ANOVA, randomized block design ANOVA, and Pearson correlation were applied to analyze the data. The major findings of this study are as follows: 1. With respect to the reasons of conflict between the administrative personnel and the teachers¡¦association, uncertain responsibilities is the most common variables, the unequal distribution of interests and bad communication the second, and different values the least. 2. The strategies used to cope with the conflict between the administrative personnel and the teachers¡¦ association were collaboration, compromise, competition, accommodation, and few avoidance. 3. The reasons of the conflict between the administrative personnel and the teachers¡¦ association were different in some parts with the background variables. 4. The strategies used to cope with the conflict between the administrative personnel and the teachers¡¦ association were different in some parts with the background variables. 5. The correlation between the administrative personnel¡¦s perception of the conflict and the strategies they use was significantly related. Based on the findings mentioned above, some suggestions are proposed as the following: 1. The educational authorities should enhance principals¡¦ leading skills and assist the teachers¡¦ associations at schools in developing and performing appropriately. 2. The school leaders should facilitate the opportunities of communication between the administrative personnel and teachers. Moreover, the clear demarcation of the staff¡¦s responsibility and the methods to solve the conflict should be made as well. 3. The administrative personnel should improve their skills in communication. In addition, the collaboration between the administrative personnel and the teachers¡¦ association should also be promoted. 4. For further studies, some other suggestions regarding the subjects, research methods, and research variables are proposed.
