  2. 2. Item bank  It is a large collection of test items that have been classified and stored in a database so that they can be retrieved at a later time or chosen for new tests.  Use of an item bank and of good item banking software is a solution to the effort and expense of preparing new items for each administration of an assessment, whether the test is used by a teacher of a small class; a university lecturer who has several large sections; or the director of multifaceted programs for certification, licensing, accountability, or norm- referenced survey testing. 28/04/2014 2

  8. 8. Before using computers  Before the advent of desktop computers, the most common item bank was a box of index cards, each containing a single item. Teachers could select the items wanted for a test, tape them to a sheet of paper, and use the copier to make sufficient copies of the examination. If more than one version were needed, items could simply be rearranged. 28/04/2014 8
  9. 9. Who can use item bank?  Anyone whose responsibilities involve preparing assessments on a regular basis will find item banking technology very useful.  In education, this group includes all classroom teachers, university instructors, directors of system-wide testing programs, directors of state testing programs, and evaluators of special projects. 28/04/2014 9
  10. 10. What can an item bank do?  Item entry and storage.  Item retrieval for reviewing items, formatting test forms, and editing and updating items.  Maintenance of item history.  Scoring and item analysis.  Preparation of records and reports, including Gradebook. 28/04/2014 10
  11. 11. Features 1. The number and type of items can faithfully reflect the nature of the knowledge domain to be measured. Unlike paper-and-pencil testing, modern computer-based testing requires a sufficient number of interchangeable items on each test objective for multiple-form and adaptive tests. 2.The items meet accepted standards of content validity and psychometric quality. They can measure what they are supposed to measure and they do so very well. 3. The item bank is easy to use and maintain. Content specialists such as teachers and lecturers can easily manage the test item database and build tests to their specifications. A development of a good test is not a difficult, lengthy and tedious task any more. 28/04/2014 11

  13. 13. Scoring  Computer administration: When tests are administered by computer, the scoring is usually, but not always, handled immediately.  Printed test forms: When printed examinations are administered, the scoring and analysis is usually a separate process.  Optic forms: The tests are automatically scored. 28/04/2014 13
  14. 14. Advantages  Teachers do not have to write new items for every examination.  Reliability in scoring; computers are more accurate.  Traditional time limits are not necessary.  Diagnostic feedback can be provided very quickly to each testee on those items answered incorrectly.  Large group of testees can be tested at the same time.  Easy to find subjects. 28/04/2014 14
  15. 15. Disadvantages  Computer equipment may not always be available, or in working order.  The graphics capabilities of many computers may be limited.  Computer anxiety is another potential disadvantage.  Differences in the degree to which testees are familiar with using computers or typewriter keyboards may lead to discrepancies in their performances on computer-assisted or computer- adaptive tests. 28/04/2014 15
  16. 16. Difficulties of Item Banking  Keeping large item banks up-to-date.  Preventing redundancy in item banks.  Keeping items from being copied and disseminated to non-members.  Determining correct key words to use for item classification. 28/04/2014 16
