face validity - a test LOOKS LIKE it tests what it's supposed to e.g. a pronunciation test which is written may be perceived by the ss as not having face validity.
content validity - thoroughness. does it test what is in the syllabus?
construct validity - the test tests what it's supposed to and nothing else.
predictive validity - how well ss will use a language or skills area in the real world.
direct test - a test of the language point or skill by focusing on that language point.
indirect testing - a test of something within the context of something else.
direct - testing use of linkers with a gap fill
indirect - testing a student's use of linkers by getting them to write a discursive essay.
* does the test rely on the subjective opinion of the marker (low reliability) or is is mechanically marked (high reliability).
