The second essay measures the perceptions of a teacher about factors, such as, syllabus, assessment, reading, learning history, national ELT policy, personality and their impacts on his teaching practice. The third essay deals with the phonological and grammatical errors of an elementary Bangladeshi student as an L2 learner of English. The fourth essay highlights the importance of three components, viz., needs analysis, testing and material development in the process of course and syllabus design and their inter-dependent relationship.
