64. Reading comprehension
• Bem (1975) has argued that androgynous people are
“better off” than their sex-typed counterparts
because they are not constrained by rigid sex-role
concepts and are freer to respond to a wider variety
of situations. Seeking to test this hypothesis, Bem
exposed masculine, feminine, and androgynous men
and women to situations that called for independence
(a masculine attribute) or nurturance (a feminine
attribute). The test for masculine independence
assessed the subject’s willingness to resist social
pressure by refusing to agree with peers who gave
bogus judgments when rating cartoons for funniness
(for example, several peers might say that a very
funny cartoon was hilarious). Nurturance or feminine
expressiveness, was measured by observing the
behavior of the subject when left alone for ten
minutes with a 5-month old baby. The result
confirmed Bem’s hypothesis. Both the masculine sex-
typed and the androgynous subjects were more
independent (less conforming) on the ‘independence”
test than feminine sex-typed individuals.
Furthermore, both the feminine and the androgynous
subjects were more “nurturant” than the masculine
sex-typed individuals when interacting with the baby.
Thus, the androgynous subjects were quite flexible,
they performed as masculine subjects did on the
“feminine” task.

study?

nurturance
b. Situation to make the sex type react

sex role concepts

b. rating cartoons and taking care of a baby
c. independence and nurturance

85. Rating Scale
• Qualitative scale
– Uses verbal descriptions to indicate student
performance.
– Provides a way to check the whether each
dimension was evidenced.
• Type A: Indicate different gradations of the dimension
• Type B: Checklist

86. Rating Scale
• Example of Type A:
– Minimal, partial, complete
– Never, seldom, occasionally, frequently, always
– Consistent, sporadically, rarely
– None, some, complete
– Novice, intermediate, advance, superior
– Inadequate, needs improvement, good excellent
– Excellent, proficient, needs improvement
– Absent, developing, adequate, fully developed
– Limited, partial, thorough
– Emerging, developing, achieving
– Not there yet, shows growth, proficient
– Excellent, good, fair, poor

87. Rating Scale
• Example of Type A: Checklist

88. Rating Scale
• Holistic scale
– The category of the scale contains several criteria, yielding
a single score that gives an overall impression or rating
Example
level 4: Sophisticated understanding of text indicated
with constructed meaning
level 3: Solid understanding of text indicated with some
constructed meaning
level 2: Partial understanding of text indicated with
tenuous constructed meaning
level 1: superficial understanding of text with little or
no constructed meaning

89. Example holistic scale

90. Analytic scale
• Analytic Scale
– One in which each criterion receives a separate
score.
Example
Criteria Outstanding
5 4
Competent
3
Marginal
2 1
Creative ideas
Logical organization

91. Rubrics
• When scoring criteria are combined with a
rating scale, a complete scoring guideline is
produced or rubric.
• A scoring guide that uses criteria to
differentiate between levels of student
proficiency.

92. Example of a rubric

93. • Rubrics should answer the following questions:
– By what criteria should performance be judged?
– Where should we look and what should we look for to
judge performance success?
– What does the range in the performance quality look
like?
– How do we determine validity, reliability, and fairly
what scores should be given and what that score
means?
– How should the different levels of quality be
described and distinguished from one another?

94. Workshop
• Work in groups and create a performance task for
one objective.
• Ensure that the performance task is aligned with
the learning competency
• Organize the presentation in using the following:
– Learning competency
– Describe the final output
– Describe what the students will do
– List the criteria
• Group presentation and feedback will follow.
