The Development of Teacher Leadership Inventory in Malaysian Educational Context

Abstract

The aim of this article is to report the development, validity, and reliability of Teacher Leadership Inventory (TLI). The sample of the study consists of 244-trained teachers who are chosen using multistage cluster sampling technique from 19 secondary schools in Perak. The first phase of the study has been carried out through exploratory factor analysis by using data from 166 teachers from 19 secondary schools in Batang Padang District, Perak. The content validity, criterion validity, and construct validity analyses have been carried out by using this set of data. The findings of this study using exploratory factor analysis through orthogonal rotation with varimax method has formed three factors, consisted of 15 items of TLI with factor loadings range from 0.54 to 0.84. The reliability Cronbach’s alpha coefficient for the overall item is 0.85, meanwhile for each factors developed ranged from 0.66 to 0.91. Meanwhile, for the second phase of the study, the confirmatory factor analysis has been carried out toward data of 244 teachers from 19 secondary schools in Perak, Malaysia. The purpose of this analysis is to support the factor structure developed from the first phase of the study. The Cronbach’s alpha of the 13 items is 0.84, meanwhile for each factor developed ranged from 0.76 to 0.88. As the conclusion, the result of confirmatory factor analysis has supported the three factors developed from the first phase of the study. As the conclusion, these analyses have generated a new pool of TLI item to measure the construct of Teacher Leadership elements in Malaysian educational context. However, the findings are valuable for the ministry of education, researchers, teachers, and teacher educators’ references, which are interested more in exploring teacher leadership self-assessment.
