I am a senior lecturer serving at Hapitigam National College of Education, which provides a three-year pre-service teacher training program leading to the National Diploma in Teaching. My educational background includes an MPhil in education, MEd, and a BA degree from the University of Peradeniya in Sri Lanka. And also, I have successfully completed Post Graduate Diploma in Education, Post Graduate Diploma in Management, Diploma in Teaching, and Diploma in Child Rights. My keen interest lies in action research, from which I have been able to gain substantial knowledge and experience for my professional development as well as for my transformational role enhancing the potentials of pre-service teacher trainees. I have been working as an Action Research Supervisor for twelve years. As a result, I have been able to help the pre-service teacher trainees develop an action-research culture, through which they try to develop an insight into professional development right at the beginning of their long journey. I have presented six action-research papers in Sri Lanka and two at international conferences in 2019 and 2020. The most recent research interests and publications are related to co-teaching in teacher education. In addition, I carried out a study investigating the motivational strategies used by principals for the improvement of job satisfaction of teachers, which turned out to be very useful for both teachers and principals. Another study on teaching environment-related activities in primary schools was conducted; emphasis was placed on integration particularly how effectively subjects can be handled. Finally, a study on co-teaching as an approach to enhance pre-service teachers’ pedagogical content knowledge was carried out. This approach created a lot of interest among teacher trainees, as co-teaching enhanced their pedagogical practices, confidence, and achievement.
