Teachers' Day: The Meanings of "Teacher" and "Lecturer" in the Context of Thai Educational History

This article aims to examine the evolution of the terms teacher and lecturer in the context of Thai educational history through both linguistic and institutional perspectives. Drawing upon the Pali–Sanskrit roots of guru and ācārya, the study traces the transformation of these concepts alongside the development of Thailand’s modern state and educational system, from the period prior to the 1932 political transformation to the enactment of the Teachers Act in 1945 and the establishment of Teachers’ Day in 1957. The article argues that the distinction between “teacher” and “lecturer” emerged primarily from institutional arrangements rather than from inherent differences in linguistic or ethical value. It further proposes that the roles of teachers and lecturers should be understood as a continuous life role encompassing the transmission of knowledge, guidance, care and support for learners and vulnerable groups within society.
