various types of assesments
Placement test asses student's level of ability so they can be place in an appropriate course or class.this type of test indicates the level which a student will learn most effectively.
Proficiency tests,on the other hand,are not based on a particular curriculum or language program.They asses the overall language of ability of students of varying levels.in other words,proficiency tests describe what students are capable of doing a language.
Achievement test are similar to progress tests in that they determine what a student has learned with regard to stated course outcomes.the content of achievement tests is generally based on the specific course content or an the course objective.Achievement tests are often consulative,covering,material drawn from an entire course or semester.
Diagnotic test identify language areas in which a student needs further help
An aptitude test measure capacity or general ability to learn a foreign or second language.
PRINCIPLE OF LANGUAGE ASSESMENT
How well a test measure what it is purposed to measure
Refers to how accurately an assesment or measurement tool taps into the various aspects of the specific construct in question.
Used to ensure that the measure actually measure what it is intended to measure (i.e. the construct). and not other variables.
Ascertains that the measure appears to be assessing the intended construct under study.
The degree to which an assesment tool
produces stabel and consistent results
Henning(1987) describes these threats to test realibility
Fluctuantions in Test Administration
Fluctuantions in Scoring
Fluctuantions in the Learner
Types of Reliability
Internal Consistency Reliability
Average Inter-item Correlation
Parallel forms reliability
Generally said to be positive or negative
"Cram" courses and "teaching to the test" are examples of such washback
Is part of both reliability and validity for all test
Refers to the availability of clear, accurate information to students about testing
For Bachman and Palmer (1996) "Test usefulness provides a kind of metric by which we can evaluate not only the test that we develop and use, but also all aspects of test development and use"
Task used in authenticity are meaningful and valuable and are part of the learning process
Task used in authenticity is to gather evidence that students can use knowledge effectively and be able to critique their own efforts
An effective test is practical
Has a scoring procedure that is specific and time-efficient
Is not excessively expensive
Is relatively easy to administer
Stays within approriate time constraints
