Further Information

This module begins by examining ELT terminology, from definitions of technical terms to the analysis of published teaching materials for sub-skills and discourse features. You will consider how these things would be taught to a specific group of learners.

You will then look at the use of authentic texts, analysing them for features of genre, and the meaning, form, use and phonological aspects of language items present in them.

Later in the course, you will examine strengths and weaknesses of student-generated spoken or written texts in relation to areas such as task achievement, cohesion, use of collocation and so on.

Following on from this, you will evaluate a range of ELT examinations and tests, looking at their effectiveness relative to their stated purpose. In a similar way, extracts from published course book materials (including resource books, teachers’ books and lesson plans) will then be studied in order to identify and discuss the underlying key language learning assumptions. You will also look at how other teachers have adapted or interpreted these materials and discuss what implications this has for classroom practice (in terms of methodological analysis, language acquisition theories, resources, and learner and teacher roles.)

All the Delta Modules are subject to Cambridge Assessment's guidelines on plagiarism for Module 3. For more detailed information about the examination please refer to the Cambridge English website.
