Egypt: Bridging the Gap between School English and Real English

Teaching English in Egypt in general and in my town Damietta in particular, is mainly directed towards helping students to pass their final exams. Unfortunately, most teachers do not adopt a long -term approach that guarantees that their students will be able to use English outside the classroom. So students only concentrate on one skill which is writing. Thus their listening and speaking skills are disabled. What is important to them is to pass the exam which is primarily based on writing .Teachers are not only concentrated with providing their students with questions that are similar to those of the final exam, particularly General Secondary Education Certificate (GSEC) Examination, so students spend most of their time answering typical exam questions.

Most students' scores are high; a lot of students get full marks. However, few students are able to communicate in English because their role plays. As a result, a lot of students complain that they are unable to understand and talk fluently with native speakers of English.

To enable students to communicate freely and spontaneously(自然地) in English, I bring features of real communication into language practice, I always ask students about their own experiences, and suggest groups of students practice what they have learned outside the classroom. This helps lower-achieving students absorb language. Furthermore, role play is a very effective way to improve speaking skills particularly if it is connected to the experience of the students.
