The purpose of this thesis are to examine whether classroom climate is affected by sex and place factors;then, to investigate the relationship between classroom climate and academic achievements. The sample selected by the method of the Stratified Cluster Random Sampling consists of one thousand four hundred and thirty─five students in twenty─nine third grade classes in high schools. All students were given the Learning Environment Inventory(LEI), composed by G.J. Anderson, H.J. Walberg, B.J. Fraser in 1982 and translated by Bao─Shan Lin in 1982, to measure classroom climate;furthermore, academic achievements were explored with help of Chinese, English and Mathematics Standardized Academic Achievement Tests edited by the Ministry of Education. In this study, the fifteen criteria of classroom climate in LEI were divided into three pats:human relationship aspect, classroom organization aspect and learning aspect. Human relationship aspect involved two kinds of relationship in school ─ the peer group relationship & the teacher─student relationship. The peer group relationship dealt with cohesiveness, competitiveness, cliqueness and friction. The teacher─student relationship involved favoritism and democracy. Classroom organization aspect included formality, disorganization, goal direction, material environment, satisfaction and apathy. Learning aspect included diversity, difficulty and speed. Mann─Whitney U Test and Product─Moment Correlation were two statistical approaches to analyze the data while the class as a whole was the unit of the analysis;besides, another two statistical approaches ─ two ─ Factors Analysis of Variance and Stepwise Multiple Regression Analysis were employed for further study when the individual student was the unit of the analysis. |
