Teachers often adopt a particular teaching and learning approach in their classes to ensure that effective learning takes place. It is assumed that teaching working adults would require the teachers to indirectly adopt an approach that suits the learners. Knowles (1978) theorized that adult learners have distinct and unique characteristics and therefore require continual opportunities to identify their needs and recognize the relevance of their learning (Knowles,1978, Zemke & Zemke, 1981). They need self directed learning opportunities in which they can actively participate. A learner-centred approach is commonly practiced in ESP classes in order to cater to learners' needs and expectations. This paper attempts to make recommendations on the feasible use of IT approach in its material use to enhance the quality of teacher expertise based on an investigation on the course effectiveness of Public Speaking to BBA executives. The data gathered is based on an investigation on the effectiveness of the teaching and learning of a Public Speaking course to a group of working adult students. We had interviewed four instructors who were involved in teaching a course on Public speaking to a group of BBA executives. Questionnaires were also distributed to the learners to mainly investigate their perceptions of the approach used by their instructors and the effectiveness of the present module in general.
