This study, therefore, aims at analysing students at the Faculty of Public and Environmental Health （PEH） at the University of Khartoum （U of K）, Sudan, needs for English language. The study adopted the needs analysis framework suggested by Dudley-Evans and St John （1998） focusing on target needs analysis, present situation analysis, and learning means needs analysis. The study used a questionnaire, a proficiency test, and an interview to collect data. The participants were 490 students at PEH （390 participated in the questionnaire and 100 in the proficiency test） and two professors at the Faculty. The study found that PEH students need English language for academic study. The students rated their proficiency as good, but the test revealed that they were of weak proficiency. All the four skills in addition to vocabulary, grammar, and pronunciation are regarded as important to the students. Similarly, almost all the sub-skills are found to be important. The students have a variety of leaming needs such as learning in pairs, groups, and through ICT. The study recommends that PEH students＇ proficiency should be raised and a course that meets the students＇ needs is needed.展开更多

Due to the many expatriates resident in the UAE English has become the main language of business, industry, and higher education. This paper looks at one of those English medium universities with an American curriculum. Since most American curriculums require substantial amounts of writing, it is important that students become competent at writing in their second language at this particular institution. This paper discusses how a novel assignment, allowing English as a foreign language （EFL） students to present readings in the classroom at an EMI university in the UAE, has helped them become both better readers and writers. Since the majority of the students are native speakers of Arabic, the project was designed with their oral traditions and proficiency in mind.展开更多
