Transcript of "Reliability (assessment of student learning I)"

  1. 1. What is Reliability?  Reliability refers to the consistency of a measure. A test is considered reliable when we get the same result repeatedly. It is impossible to calculate reliability exactly, but it can be estimated in a number of a different ways.
  2. 2. Errors of measurement Test-Takers- this sources of errors takes place into consideration what is happening within the individual like fatigue, hunger, headache, emotional upset and anxiety growth.  Test- Administration- it can be cause by lighting of examination room, room temperature, noise, sitting arrangement, instruction, attitude of test examiner. 
  3. 3. Test- Scoring- factors that contribute to error in scoring include miskey, wrong answer to test items, mistake in correcting answer, mistake in the use of correcting pencil and subjective scoring.  Test Itself- the difficulty of the test, may contain poorly constructed items that gives clues, ambiguous items, very easy items and very difficult.  Expert agree that the longer the test the higher is its reliability.
  4. 4. Different Methods Of Reliability Test-Retest Reliability- the test is administered twice at two different points in time. It is best use for things that are stable over time.  Inter-rater Reliability- assess by having two or more independent judges score the test. The score has been compared to determine the consistency of the raters estimate. 
  5. 5. Parallel Forms Reliability- gauged by comparing two different test that were created using the same content.  Internal Consistency Reliability- use to judge the consistency of results across items on the same test. When we see a question that seems very similar to another test question. It may indicate that two questions are being use the gauged reliabity. 
  6. 6. Split-half- give parallel form of test with in crease time interval between forms using Pearson R formula.  Kuder Richardson- give the test once then correlate the proportion and percentage of the student passing and not passing a given items with the measure of internal consistency. 
