To tell the age of most layered rocks, scientists study the fossils these rocks contain. Fossils provide important evidence to help determine what happened in Earth history and when it happened. The word fossil makes many people think of dinosaurs. Dinosaurs are now featured in books, movies, and television programs, and the bones of some large dinosaurs are on display in many museums.
In this quotation the abbreviation TLU stands for âtarget language useâ; Bachman and Palmer define the TLU domain as the âsituation or context in which the test taker will be using the language outside of the test itselfâ (Bachmann and Palmer 1996: 18). Other definitions of authenticity are rather similar. The Dictionary of language testing, for instance, states that âa language test is said to be authentic when it mirrors as exactly as possible the content and skills under testâ (Davies 1999: 13).
TEFL stands for Teaching English as a Foreign Language. TESL stands for Teaching English as a Second Language. An English teacher who teaches English to speakers of other languages in a non-English speaking country is teaching EFL.For example, an American living and teaching English in Spain is an EFL teacher.ESOL stands for Teaching English to Speakers of Other Languages. These abbreviations could render EFL-ESL differences irrelevant on paper, but the differences are still important to the teacher preparing his or her English lesson plans.
