The Role of Teachers’ Professionalism on School Effectiveness

The purpose of this study was to investigate the role of teachers’ professionalism in school effectiveness. The research population, 1109 people, consisted of all the teachers of smart schools in district 5, Tehran, from which 240 subjects were selected using simple random sampling. This quantitative, descriptive research followed a survey-correlation design. The instruments employed included a researcher-made 25-item questionnaire about teachers' professionalism based on the Sachs model (2003) and a researcher-made 18-item questionnaire on school effectiveness based on the Chen and Lane model (2011). The reliability and validity of the instruments were measured by using Cronbach's alpha and confirmatory factor analysis, respectively. The results indicated that the reliability and validity were desirable. For data analysis, descriptive (center and scatter plot) and inferential (single sample, Pearson correlation coefficient and linear multivariate regression) statistics were employed by using SPSS software. The findings revealed that the teachers' professionalism had a positive, direct and significant relationship with the effectiveness of smart schools and its components (α>0.05). In addition, the components of teachers' professionalism had a positive, direct and significant positive effect on the effectiveness of smart schools (α>0.05).
