摘要:AbstractCompetent lecturer with strong commitment in teaching and supervision should be able to cope with the vision of UniversitiKebangsaan Malaysia (UKM), particularly to produce graduates who are knowledgeable, confident and contributes productively to the existence of a dynamic society. Lecturer's roles to teach and supervise should be supported by a strong curriculum and education program which are current and relevant. Lecturers are demanded to maintain the process of well learning in an effort to improve the quality of education. Teaching is an ongoing process which needs to be enhanced through research and knowledge development. Thus, lecturers should take into account any changes in educational policy and ensure the quality of teaching and learning are not affected. From 2003, the government has implemented changes in teaching Mathematics and Science from the Malay language to English (PPSMI). This has an impact on teaching and learning in Higher Education Institutions, including UKM. This study aims to review the transformation of teaching and learning Mathematics in English based on student's perception. It is also to evaluate whether PPSMI can boost students’ mastery of knowledge. From the results, students are generally satisfied with the teaching and learning conducted in English at the School of Mathematical Sciences, UKM.
