Transformational Leadership of Directors affecting Work Effectiveness ofTeachers in Educational Institutions under the Office of Nakhon Phanom Vocational Education Commission

Abstract

This research was conducted with the objectives to study 1) transformational leadership level of directors; 2) work effectiveness level of teachers in educational institutions; 3) relationship between directors’ transformational leadership and teachers’ work effectiveness; 4) predictive power of transformational leadership of directors affecting work effectiveness of teachers and 5) approaches concerning the development of transformational leadership of directors. As a correlational research, it was divided into 2 phases. The first phase was the study of level of transformational leadership and work effectiveness of teachers in educational institutions. The second phase was the building of proposal on the approaches towards directors’ transformational leadership development. The tool of choice in data collection was a 5-level rating scale questionnaire with IOC  ≥ 0.30, discrimination power between .55 - .88 and reliability value at 0.98. Statistics used in data analysis comprised frequency, percentage, mean, standard deviation and Pearson product-moment correlation coefficients, as well as stepwise multiple regression analysis

The findings are as follows. 1.) In an overall, transformational leadership of directors of educational institutions under the Office of Nakhon Phanom Vocational Educational Commission is at a high level. 2.) The overall work effectiveness of teachers in the learning system of educational institutions under the Office of Nakhon Phanom Vocational Educational Commission is at a high level. 3.) Transformational leadership of directors has a medium level positive relationship withwork effectiveness of teachers in educational institutions under the Office of Nakhon Phanom Vocational Education Commission with a statistical significance at .01 level. 4.) The 2 aspects of transformational leadership affecting work effectiveness of teachers are intellectual stimulation (x₂) and individualized consideration (x₄) with a statistical significance at .05 level. Predictive power of these 2 variables is at 21.6%. The predictive equation can be constructed as follows.

The predictive equation in unstandardized score:

Y^’= 2.485 + .041 x₂+.022 x₄

            The predictive equation in standardized score: 

            Z^’ _y= .284 Z₂ + .212 Z₄

1. The author proposes that 2 aspects of transformational leadership of directors should be further enhanced, which are intellectual stimulation and individualized consideration.
