How are a dog and a cat alike? Student: They are both pets and animals. Vocabulary: In this test, the examiner orally presents a series of words and asks the child to define them.

1. Specific Learning Disabilities

2. • Normal Intelligence Range
• Terminology established in 1963 by Sam
Kirk
• Causation varied (minimal brain injury,
perceptual disorders, IQ-achievement
discrepancy, environmental, etc.)

3. Federal Definition of
Specific Learning Disabilities

4. The majority of states use a definition based
on the definition of the federal government.
This definition, first signed into law in
1977, was—with few minor wording
changes—adopted again in 1997 by the
federal government:
Federal Definition

5. A. GENERAL—The long term “specific
learning disability” means a disorder in
one or more of the basic psychological
processes involved in understanding or in
using language, spoken or written, which
disorder may manifest itself in an
imperfect ability to listen, think, speak,
read, write, spell, or do mathematical
calculations
Federal Definition

6. B. DISORDERS INCLUDED—Such term
includes such conditions as perceptual
disabilities, brain injury, minimal brain
dysfunction, dyslexia, and developmental
aphasia
Federal Definition

7. C. DISORDERS NOT INCLUDED—Such
term does not include a learning problem
that is primarily the result of visual,
hearing, or motor disabilities, of mental
retardation, of emotional disturbance, or
of environmental, cultural, or economic
disadvantage.
Federal Definition

8. Prevalence—Learning Disabilities
• 5 – 6% of students ages 6 to 17 are learning
disabled
• Learning disabilities is the largest category
in special education

9. Although the testing practices of today
differ markedly from those of 4,000 years
ago, when formal testing was first
introduced, the premise has remained very
much the same, to distinguish those who
are successful at solving problems from
those who are not.

10. The first effective test of intellectual
ability was devised in the early
1900s by French psychologists
Alfred Binet, Victor Henri, and
Theodore Simon.
Binet and Simon went to great
lengths to differentiate between the
concepts of natural intelligence and
acquired intelligence. They were
interested in measuring one’s
capacity to learn rather than simply
knowledge gained through
instruction.

11. The Influence of David Wechsler
David Wechsler’s (1896-1981)
influence on assessment in the
schools has been profound.
The Wechsler scales are a series of
three individually administered
intelligence tests, modeled after one
another, in which a person’s
intellectual abilities are described
using a verbal/motor framework.
The Wechsler scales have provided
the preferred vehicle for the
identification and classification of
countless school-age children for
nearly half a century.

12. Curriculum-Based Assessment
Curriculum-Based Assessment
(CBA) is a type of performance
assessment that is widely used in
special education. CBA strengthens
the connection between assessment
and instructors by evaluating the
student in terms of the curricular
requirements of the student’s own
school or classroom. For example,
if the student is expected to spell
certain words in the classroom, the
assessment measures the student’s
performance on those words.

13. Criterion-Referenced Tests
Criterion-referenced tests measure a student’s mastery of
specific skills. For example, does the pupil recognize –ing
endings? Does the student know the meaning of the prefix dis-?
Can the student subtract single-digit numbers through 10?
The teacher can set an acceptable criterion for mastery, such as
90 percent. When that performance level is reached, the
student is taught the next skill in the sequence.
Criterion-referenced tests describe rather than compare
performance, measuring mastery levels rather than grade
levels.

14. Formal Standardized Tests
norm-referenced
 The test is usually available in more than one form so that a student can be
examined more than once without obtaining a high score due to practice.
 The test is accompanied by a manual giving directions for administration,
scoring and interpretation.
 The manual contains grade norms, age norms, and possibly percentile ranks or
some form of scaled scores.
The manual has information on validity (the degree to which the test measures
what it is supposed to measure). The manual also shows reliability (consistency
or similarity of performance). A reliability coefficient of 0.90 indicates that if the
test were given to the student again, it is 90 percent likely that the student would
obtain a score in the same range.

32. Tests of Mental Abilities and Mental Processes
Commonly used individual intelligence tests that are
typically administered by psychologists are the WISC-III
(Wechsler Intelligence Scale for Children- Third Edition),
the Stanford-Binet Intelligence Scale, - Fourth Edition, and
the Kaufman Assessment Battery for Children (K-ABC).
The purpose of general intelligence tests is to assess the
global aspects of intellectual ability. These tests provide
information about the student’s aptitude for learning and
specific cognitive attributes.

33. WISC-III Verbal Tests
These tests use oral language for administration and student
responses. Their descriptions follow.
Information: In this test, the examiner orally presents a series of
questions about common event; objects, places; and people. The child’s
answers indicate knowledge about this common information.
What does the
statue of liberty
stand for?
Freedom and
Justice for
All?

34. WISC-III Verbal Tests
Similarities: In this test, the examiner orally presents a series of pairs of
words. The child explains the similarity of the common objects or
concepts the words represent.
What do an
apple and an
orange have in
common?
They are
both
fruits?

35. WISC-III Verbal Tests
Arithmetic: This test is a series of orally presented arithmetic problems.
The child mentally solves the problems and responds orally.

40. WISC-III Performance Tests
Coding: This test consists of a series of simple shapes (Coding A) or
numbers (Coding B), each paired with a simple symbol. The child is
required to draw the symbol in its corresponding shape (Coding A) or
under its corresponding number(Coding B) according to a key.
