The Investigation on Current Situation of Sri Lankan School-Based Teacher Development Programs

Abstract
Teachers have to update and intensify their knowledge, skills, attitudes and practices to meet students’ current expansive demand. Therefore in this context, School-Based Teacher Professional Development (SBTD) is a very important concept, because it allows teachers to plan, organise and implement their own professional development programs, considering their particular needs, as well as those of students and school. However, this concept has not been extensively developed in the Sri Lankan education context. Focusing on the Sri Lankan school context, this study examines the possibilities, effectiveness, strategies, issues and challenges involved in implementing these programs in the teachers’ professional development. Simultaneously, the situation of the Non-School-Based Teacher Development (NSBTD programs are also examined because these are currently prominent and this study assumed that both programs need to be integrated in order to provide balanced teacher professional development. The qualitative research approach and the case-study method has been employed. The data were collected by conducting interviews, non-participative observation and documentary searching. The findings shows Principals were not fully aware about the concepts of SBTD programs and principals of this study pointed out that currently the SBTD concept is not popular in the system.According to the findings, strong recommendations were proposed and relevant guidelines were suggested for future researches.
