To understand the current status of class cluster classroom in Kao-ping area which adopts open space design and the class management performance run by teachers on the class cluster classroom which adopts open space design. 3. To study and analysis on the differences of the satisfaction and the class management performance of class cluster classroom, which adopts open space, reflected by teachers of different background variables. 4. To investigate the relationship and forecasting between the cluster classroom satisfaction and the class management performance reflected by teachers in the elementary school. 5. Suggestions will be proposed based on the study results so as to be used by teachers who practically operate and apply class cluster classroom of open space and by persons who are going to perform planning on school building of open space in the elementary school. ¡§Questionnaire survey¡¨ will be the main method used in this study, the sampled targets will be from all the teachers, who adopt open space in designing class cluster classroom, in the schools of Kaohsiung City, Kaohsiung County and Pingtung County; the number questionnaires are about 356 copies and a total of 310 effective questionnaires are recycled. The research tool in this study is self-developed ¡§A questionnaire on the relationship between class cluster classroom with open space design and the class management performance¡¨, statistical methods used include: descriptive statistical analysis, independent sample t test, single factor ANOVA (analysis on variance), Pearson product-moment correlation, stepwise multiple regression analysis, etc. The following conclusions are derived based on the results of this study: 1. Teachers have above-average evaluation on class cluster classroom with open space design. 2. Class cluster teachers in elementary schools have higher class management performance. 3. For teachers in Kaohisung city, teachers with part-time administrative duties, teachers in L shape class cluster module or teachers with 2 years (included) or below of teaching experiences in this school show higher satisfaction on the class cluster classroom adopting open space design. 4. For teachers in schools of Kaohsiung city, in schools of L shape and ¡§Arc¡¨ shape class cluster modules,all show better class management performance. 5. Class cluster classrooms adopting open space design is helpful in improving class management performance. 6.
