WCPA`s School Division Power Point Presentation on WJ-IV

Report
Introducing the fourth generation
of the Woodcock-Johnson
Structural Changes
NEW! Oral Language Battery
(All Oral Language tests moved here and more.)
8 New Tests
WJ-III Tests  WJ-IV Tests:
•
removed,
•
•
relocated,
•
•
To the battery in which it is most appropriate/relevant
renamed,
•
•
Due to feedback and/or more powerful tests replaced these
To more accurately reflect the task
and/or revised
•
•
Items added to lower basal/increase ceiling
Content updated
Most Significant Changes to the
WJ IV Interpretive Model
• Most contemporary reflection of CHC theory
• Support for changes from neurocognitive,
neuropsychological, and developmental research.
Primary Interpretive Changes
Short-term Working Memory
Auditory Processing
Speed of Lexical Access
GIA Cluster
Changes to Interpretive Model:
General Intellectual Ability Cluster
Gc
Oral Vocabulary
Criticism over analogies in Verbal Comprehension
Gf
Number Series
Most powerful predictor of ACH of all tests; Feedback
about structure learning tasks from Concept
Formation/Analysis Synthesis
Gwm
Verbal Attention
Gs
Letter-Pattern
Matching
(Pair Cancellation just as strong of a predictor, but they
wanted a balance of types of stimuli); Perceptual Speed
Ga
Phonological
Processing
Cognitive complexity; highest Ga loading on OL’s new
Segmentation test; as good of a measure of ‘g’ as Gf
(0.804).
Glr
Story Recall
WJIII Visual Auditory Learning w rebus was too juvenile
for older children.
Gv
Visualization
Different measure of Gv than WJIII.
Ecological; Authentic Measure; Different measure.

Summary: WJ IV OL
• Yields important information about oral
language abilities, phonetic coding, speed of
lexical access
• Explores possible contributing factors in
reading disabilities and dyslexia
• Includes 3 parallel tests in Spanish and allows
comparison of English and Spanish oral
language abilities
• Provides an important diagnostic supplement
to WJ IV COG/WJ IV ACH

Gf-Gc Composite
• Composed of 4 tests (2 Gc and 2 Gf)
1: Oral Vocabulary (Gc)
2: Number Series (Gf)
8: General Information (Gc)
9: Concept Formation (Gf)
• Considered a hybrid model
‒uses traditional ability/achievement methodology
‒interprets discrepancies as a profile of intraindividual strengths and weaknesses
• Useful in gifted, SLD, and intellectual disability
evaluations
Scholastic Aptitudes
Each Scholastic Aptitude cluster is a 4-test cluster
designed to provide the best empirical and researchbased, cognitive predictor of achievement.
Compares most relevant cognitive abilities to current
levels of achievement in specific areas to determine if
ability is consistent with achievement (aptitudeachievement consistency).
Six scholastic aptitudes increase precision of
prediction.
Six Scholastic Aptitudes
2 Reading
2 Math
2 Writing
Perceptual Speed (Gs-P)
• The ability to rapidly perform simple tasks that use
symbols, such as letters or numbers
• Composed of Test 4: Letter-Pattern Matching and
Test 11: Number-Pattern Matching
• An important narrow ability with unique clinical
significance
– Related to orthographic processing
– Needed for decoding, encoding, reading fluency
– Involved in math
Quantitative Reasoning (Gf-RQ)
• The ability to reason deductively and inductively
with numbers, mathematical relations, and
operators
• Composed of Test 2: Number Series and Test 15:
Analysis-Synthesis
• The complexity of this cluster makes it a strong
predictor of achievement, especially math
problem solving.
Number Facility (Gs-N)
• The ability to perform basic arithmetic operations
quickly and accurately
• Composed of Test 10: Numbers Reversed and Test
11: Number-Pattern Matching
• Compare task demands
– Numbers Reversed—oral presentation
– Number-Pattern Matching—visual
– Timed task versus untimed (but stimuli is temporary)
Cognitive Efficiency (Gwm+Gs)
• A measure of short-term working memory (Gwm)
and processing speed (Gs)
• Composed of Test 4: Letter-Pattern Matching and
Test 10: Numbers Reversed
• Extended cluster includes two additional tests: Test
3: Verbal Attention and Test 11: Number-Pattern
Matching
• Important diagnostic cluster
– Gwm and Gs are both foundational for complex
cognitive functioning.
– Limits can interfere with performance.
Auditory Memory Span (Gwm-MS)
• Ability to hold auditory information in immediate
awareness
• Composed of Test 18: Memory for Words and
from the WJ IV OL, Test 5: Sentence Repetition
• Consider impact of language
– Memory for Words—unrelated words
– Sentence Repetition—meaningful sentences
Vocabulary (Gc-VL, LD)
• A measure of lexical knowledge and language
development
• Composed of Test 1: Oral Vocabulary and Test 1:
Picture Vocabulary from the WJ IV OL
• Both tasks presented orally
• Good predictor of reading performance
• Compare to WJ IV ACH Test 17: Reading
Vocabulary
General Intellectual Ability Options
• General Intellectual Ability (GIA)

Median reliability: .97
• Brief Intellectual Ability (BIA)

• Offers 7 core tests in the Standard Battery to obtain
key information efficiently
• Measures important cognitive abilities helpful for
understanding learning problems
• Provides the new Gf-Gc comparison procedure, a cuttingedge approach for SLD and intellectual disability evaluations
• Co-normed with WJ IV Tests of Achievement and WJ IV Tests
of Oral Language
