Research Paper (postgraduate) from the year 2023 in the subject Pedagogy - Adult Education, , language: English, abstract: This study aims to analyse the effectiveness of the teaching internship component attached to the Higher National Diploma in English (HNDEn) program conducted by Sri Lanka Institute of Advanced Technological Education (SLIATE). It fundamentally investigates whether the teaching internship has formed an effective impact on the lives of HNDEn students in becoming successful beginning teachers and further, how it has contributed to the overall design of the HNDEn program to achieve the goal of producing successful teachers. The study adopts qualitative research design in collecting and analyzing the data which are gathered from HNDEn teacher interns training at the schools of the government sector in Sri Lanka. Findings are analysed through thematic analysis. Multiple themes pertaining to the impact of HNDEn curriculum and feedback on the teaching practice, academic-related opportunities faced by the interns and the areas of further improvement currently needed emerge from the analysis, suggesting that the interns are exposed to a variety of experiences during the internship which function both constructively and disparagingly in molding their role as teachers. The results of the study carry a pedagogical value as they are representative of what a teacher intern undergoes during the beginning phase of the teaching career, which leads to the understanding and designing of an effective teaching internship.
