The Effects and Implications of The Use of English as a Medium of Instruction in Mathematics on Thai Learners

Abstract

Education is founded on such fundamental aspects as communication. Acquisition of knowledge can therefore only take place in the presence of effective communication. The medium through which communication takes place assumes a central role in the entire process of learning and teaching. Mathematics concepts, being perceived by many as challenging, require a medium of instruction that is clear and easily understandable by learners. The objective of this study was to determine the effects, opinions and implications of the use of English in teaching Mathematics in Thai public schools. Three instruments; Questionnaires, an Interview Schedule and a written test were employed to realize the objectives. It was established that English as a medium of instruction in teaching Mathematics has fundamental effects on the Thai learners, including but not limited to misperception, demotivation and academic development impairment. The learners suggested code-switching as a medium of instruction.
