3. RELIABILITY AND VALIDITY
Reliability is the consistency of the
assessment in producing the same score on
different testing occasion
Validity however is the extent in which it is
to measure what is supposed to be measured
4. Reliability has a feature of the appropriate
consistency of assessment, called inter-rater-
reability
It is the absolutely important onein which itis to
ensure both the consistency and fairness of rating
The feature applies a scoring rubric for each macro
skill or major aspect of English skill
The scoring rubric contains 4-6 levels from the
early to exceptionally fluent
5. In order to apply the reability using scoring
rubric by another teacher (unexperienced
teacher), staff developer or teacher can be
the facilitator for training raters, here are
the considerations:
Orientation to the assessment task
Clarification of the scoring rubric
Practice scoring
Record the scores
Check reability
6. Next step of authentic assessment is
“Grading”
It is systematically formed as a report card
It functions as a part of communication
among teachers, students and parents
The grade it self has 2 basic purposes, what
are they? Anyone can answer them?
7. It reflects students accomplishment and to
motivatestudents
It is meant as the level or rank order of students
performance
In the report card, we can review some learning
factors, considered such as:
Level of effort
Attitute
Ability
Behavior
attendance
8. Now everybody must have understood the
reability in authentic assessment, don’t they?
Then, let;s move on to the next topic
discussion
9. VALIDITY has two most concern types inthe
authentic assessment
Content validity,the respondence between
curriculum objectives and objective being
assessed.
consequential validity, thw way in which the
assessment is used for benefiting teaching
and learning process and to benefit students
