To be fully equipped for a productive future, students need sound communication skills. As English has become the global business language, once students enter the world of work, it becomes critical to communicate ideas in English. In the tertiary learning environment, most text books are written in English, and so are most internet research papers. English competence therefore empowers the learning process.
This presents a challenge as most students do not have English as a first language. Educators also find it challenging to coach language skills to large groups of students who are at different levels of proficiency. They also wish to be spared the laborious task of marking English grammar. Their energy can be more productively focused on the interactive aspects of the language, as well as the discipline-specific vocabulary and expression of ideas.
