The lexical approach is a method of teaching foreign languages described by Michael Lewis in the early 1990s. The basic concept on which this approach rests is the idea that an important part of learning a language consists of being able to understand and produce lexical phrases as chunks. Students are taught to be able to perceive patterns of language as well as have meaningful set uses of words at their disposal when they are taught in this way. In 2000, Norbert Schmitt, an American linguist and a Professor of Applied Linguistics at the University of Nottingham in the United Kingdom, contributed to a learning theory supporting the lexical approach he stated that "the mind stores and processes these chunks as individual wholes." The short-term capacity of the brain is much more limited than long-term and so it is much more efficient for our brain to pull up a lexical chunk as if it were one piece of information as opposed to pulling up each word as separate pieces of information. In the lexical approach, instruction focuses on fixed expressions that occur frequently in dialogues, which Lewis claims make up a larger part of discourse than unique phrases and sentences. Vocabulary is prized over grammarper se in this approach. The teaching of chunks and set phrases has become common in English as a foreign or second language, though this is not necessarily primarily due to the Lexical Approach. This is because anywhere from 55-80% of native speakers' speech are derived from prefabricated phrases. Fluency could be considered unachievable if one did not learn prefabricated chunks or expressions. Common lexical chunks include: Have you ever... been / seen / had / heard / tried Most language learners are accustomed to learning basic conversation starts, which are lexical chunks, including: "Good morning," "How are you?" "Where is the restroom?" "Thank you," "How much does this cost?" Language learners also use lexical chunks as templates or formulas to create new phrases: What are you doing? What are you saying? What are you cooking? What are you looking for?
Syllabus
The lexical syllabus is a form of the propositional paradigm that takes 'word' as the unit of analysis and content for syllabus design. Various vocabulary selection studies can be traced back to the 1920s and 1930s, and recent advances in techniques for the computer analysis of large databases of authentic text have helped to resuscitate this line of work. The modern lexical syllabus is discussed in Sinclair & Renouf, who state that the main benefit of a lexical syllabus is that it emphasizes utility - the student learns that which is most valuable because it is most frequent. Related work on collocation is reported by Sinclair and Kennedy, and the Collins COBUILD English Course is cited as an exemplary pedagogic implementation of the work, though "in fact, however, the COBUILD textbooks utilize one of the more complex hybrid syllabi in current ESL texts". Sinclair & Renouf find that, claims made for the lexical syllabus are not supported by evidence, and the assertion that the lexical syllabus is "an independent syllabus, unrelated by any principles to any methodology" is subject to the criticism levelled by Brumfit against notional functional syllabi, i.e. that it takes no cognisance of how a second language is learned. Since these observations were made, however, Willis and Lewis have gone some way to provide such a theoretical justification.
