research Norm Sample and Statistics Sample Size 1,985 individuals
aged 3-0 - 21-11
tested at selected intervals
testing conducted 04/92 - 08/93 Selection Method randomized sampling used
norms closely fit to US population
gender results = 48.6% male - 51.4% female
socioeconomic status considered from 'mother's education level' statistic Reliability written expression - .84 - .94
language composite - .90 - .95
aged 5-0 to 21-11 Split-Half Reliability Test-Retest Reliability written expression - .87 - .88
language composite - .90 - .87
aged 8-0 to 18-11 Interrater Reliability only computed for written expression scale
.91 - .98
aged 5-0 - 21-11 Standard Error of Measurement written expression - 3.7 - 7.2 (mean -5.5)
language composite - 3.7 - 4.7 (mean 3.9)
aged 5-0 21-11 - Validity Content Validity researched, weighed against writing samples
samples from age groups 5-0 - 21-11
hypothetically and theoretically approached Construct Validity measured from intercorrelations between subtests
listening comprehension - .30 - .73 (mean - .57)
oral expression - .75 - .47 (mean - .66)
oral composite - .74 - .61 (mean - .67) Criterion-Related Validity collected during standarization of test
form-a form-b results related
details otherwise unaddressed Administration Requirements * The OWLS can be administered by anyone with a background or prior experience in assessment, to an individual, or to a group, 2 -15 examinees in size *listening comprehension
oral expression scales
-packaged seperately- Written Expression Scale Administration Administration 1) begin at age appropriate section. read sentence aloud from the written expression scale administration card
2) allow 30 seconds for examinee to begin responding in response booklet.
3) when student responds, move on to next sentence in age appropriate section. if no response, say, 'lets go on' and move on to the next item
4) collect response book at end of age appropriate section, score after session, when examinee is no longer present. Recording Raw Score Scoring Rules *Basal and Celing determined by age appropriate groups. Administer ALL items in age appropriate group. Celing can be reached at frustration level in some age sections amount of possible points earned increase as difficulty increases
simple sentences (age group 5-7) - 1 pt max
complex sentences (age group 19 - 21) - 4 pts max
scoring rules consider handwriting, spelling, comprehension, syntax, punctuation, content, and detail
rules for each sentence expicitly stated in written expression scale record form
circle 1 for point awarded, 0 for no point awarded, sum up total at the end of age appropriate section. Sum - total raw score. Determining Normative Score chart based scoring all raw scores transfer to charts in appendix B of manual
once transferred, interpreted scores are written in score summary on written expression scale
data then transfers to score profile, which shows the error of measurement in a visual shading graph Demonstration *appendix B is a complete guide to turning the raw data into interpreted scores, and features values matching all possible raw data outcomes. Pros and Cons Norm sample features unique research
Scoring is completely guided
Norm sample considers LD and impaired
Good informal to follow WJ-III writing
Excellent manual, informative and useful
Reliability avg to above avg range
Reasonable administration time Overall Opinion * I believe the OWLS writing assessment would be useful to have around. although out of date, it is easy to jump into, easy to administer, and provides another meter of written expressive ability. it would be useful as a follow up assessment or an informal assessment to support findings from a prior writing asessment. * The OWLS can be administered to gifted and out-of-level students, and has been norm sampled for individuals with learning and cognitive disabilities Out of date assessment, OWLS II available
Other subtests packaged separately
Validity lacks statistical support
Scoring difficult without other subtests
Chart scoring = only option
Rules of scoring extensive
Smaller norm sample
