Abstract:
The purposes of this study were to investigate student factors, classroom factors and school factors affecting the school effectiveness of primary schools under Office of the Basic Education Commission and to create the model of causal structural relationship for multi-levels factors affecting the effectiveness of primary schools under Office of the Basic Education Commission. The samples in this research were drawn from all related people in 43 primary schools under Office of the Basic Education in central region, academic year 2013, by using a Taro Yamane formula for calculating the sample size. Simple random sampling was used to select the schools. The informants included 43 administrators, 215 teachers and 8,636 students. The obtained samples were from all the students in the selected classrooms. The instruments used in this research were three sets questionnaire including: Set 1) a questionnaire divided into three parts used for collecting student data with 0.92-0.93 of the reliability. Set 2) a questionnaire divided into 5 parts use for collecting classroom data with 0.74-0.96 of the reliability. Set 3) a questionnaire divided into 5 parts use for collecting school data with 0.89-0.98 of the reliability. The statistics used for data analysis were percentage, mean, standard deviation, skewness coefficient and kurtosis coefficient, standard deviation, and Multi-level analysis with Hierarchical Linear Model (HLM) at three levels using HLM version 7, the code number : 445D-C4F7-592B-6E42. The findings were as follows: 1. Factors Affecting the Effectiveness of primary schools under Office of the Basic Education Commission components composed of: The student factors were the students background knowledge, learning behavior, learning attitude, and parents educational levels. They most positively affected the students learning achievement. The classroom factors were the teachers teaching behavior which most positively affected the students learning achievement. The teachers social support was negatively affected the students learning achievement. For the school factors, the study found that: the administrators age negatively affected the students learning achievement. The administrators instructional leadership positively affected the students background knowledge, but negatively affected the students learning attitude. 2. The model of causal structural relationship for multi-level factors affecting the effectiveness of primary schools under Office of the Basic Education Commission were as follows: Within-unit Model The effectiveness of primary schools under Office of the Basic Education Commission (SACij) = 0.3649 + 0.0212 parents educational level (SED) + 0.09828 students attitude (SAT) + 0.0618 learning behavior (SBE) + 0.7529 student background knowledge (SKN) + residual variance for the student factors ( )Between-unit Model The effectiveness of primary schools under Office of the Basic Education Commission (SACij) = 0.3649 + (-0.0507) TSSU + 0.0366 TTEA + (-0.0010) ADAGE + 0.0212 parents educational levels (SED) + 0.09828 students attitude (SAT) + (-0.01812) instructional leadership (ADIL) + 0.0618 students learning behavior (SBE) + 0.7529 student background knowledge (SKN) + 0.0212 instructional leadership (ADIL) + residual variance for the classroom factors ( )
