The document discusses various properties of assessment methods including validity, reliability, and approaches to checking reliability. It defines validity as the degree to which a test measures what it is intended to measure. Reliability refers to the consistency and stability of results produced by an instrument. There are four main methods to check reliability: test-retest, parallel-forms, internal-consistency, and inter-rater reliability. The document also stresses the importance of students understanding learning targets and assessment methods.

RELIABILITY OF TESTS

12. Used to assess the
degree to which different
raters/observers give
consistent estimates of
the same phenomenon

13. Used to assess the
consistency of a
measure from one time
to another.

14. Used to assess the
consistency of the results
of two tests constructed
in the same way from the
same content domain

15. Used to assess the
consistency of results
across items within a test

16. • - Students need to know exactly
what the learning targets are and
what method of assessment will be
used

17. • Assessment has to be
viewed as an
opportunity to learn
rather than an
opportunity to weed
out poor and slow
learners.

18. • Teachers should be familiar
with the test,
• number of items is not
complicated.
• Implementable

19. • The term “ethics” refers o the
question of right and wrong.
• Webster defines ethical(behavior)
as „conforming to the standards of
conduct of a given
profession or group‟.
