Significant differences between individual subtest scaled scores and average scaled scores on the Wechsler Preschool and Primary Scale of Intelligence-Revised

This paper presents age-referenced tables that are used for determining significant differences between individual subtest scaled scores and average subtest scores on the Wechsler Preschool and Primary Scale of Intelligence-Revised (WPPSI-R). The tables provide differences required at the .05 and .01 levels of significance between any Verbal scale subtest and the average of Verbal scale subtests, any Performance scale subtest and the average of Performance scale subtests, and any subtest with the average of all subtests administered. The information presented is useful for WPPSI-R profile analysis.     

A comparison of learning disabled college students' achievement from WRAT and PIAT grade,standard, and subtest scores

Although there have been a number of studies that compared the test results of the Wide Range Achievement Test (WRAT) and the Peabody Individual Achievement Test (PIAT), none had been accomplished with a group of college-aged learning disabled students. Indeed, few researchers had investigated populations over 16 years of age, and none had compared grade scores and standard scores with appropriate subtest scores as derived from these two instruments. With the recent emphasis on postsecondary education for the learning disabled, it is deemed critical that researchers should develop a data base for study of this population. The current research demonstrated that although both tests purport to measure academic achievement in reading, spelling, and arthmetic, in reality, significantly different scores are derived when WRAT (1965, 1978) norms are compared to PIAT (1970) norms as stated in grade scores and standard scores. These significant differences in the grade and standard scores clearly indicate that the WRAT and the PIAT, particularly in regard to arthmetic and to a lesser degree to reading, are not interchangeable instruments of academic achievement.     

Relating deaf students' reading and language scores at college entry to their degree completion rates

Graduation patterns were examined for 905 deaf students (1990-1998) at the National Technical Institute for the Deaf. Students with higher reading and language skills had the best overall graduation percentage. Comparison of recipients of different degrees--bachelor of science (BS) versus fine arts (BFA); associate of applied science (AAS) versus occupational studies (AOS)--showed 92% of BS and 82% of AAS graduates reading at the 9th-grade level or above, versus 65% of BFA and 47% of AOS graduates. Interestingly, 80% of non-degree-earning students read at the 9th-12th grade levels; in absolute terms, they outnumbered graduates with similar reading skills in the AAS and BFA programs combined, and in the BS program. This indicates a need for improved counseling, placement, and retention strategies. Students performed similarly across degree categories, regardless of curriculum requirements and difficulty. Only non-degree-earning students had significantly lower grade averages.     

An examination of the evidence-based literacy research in deaf education

The ability to read and write for a variety of purposes is essential to success in school and in contemporary society. The purpose of this investigation was to conduct an exhaustive review of the literature and a meta-analysis of literacy research in the field of deaf education. Computer and manual searches of 40 years of peer-reviewed journal articles were conducted. A total of 964 articles related to literacy and deafness were identified and examined; 22 articles met the criteria for inclusion in the review. Results indicate that (a) no two studies examined the same dimension of literacy; (b) there was a paucity of well-designed group studies; (c) there were no systematic replication of studies; (d) there is limited data to establish evidenced-based practices. Consequently, increasing the quantity and improving the quality of research in the field is recommended.     

The Wechsler Preschool and Primary Scale of Intelligence: Difficulty order of subtest questions

Theoretically and pragmatically the subtest questions of the Wechsler Pre-school and Primary Scale of Intelligence are assumed to be ordered from least to most difficult. The purpose of this study was to test whether or not the order was appropriate for a sample other than that used for standardization. Data consisted of test records of 89 females and 62 males tested at a private school over four years. Mean Full Scale IQ of the sample was 118. Calculation of proportion of the sample passing each item and Guttman Reproducibility Coefficients for each subtest suggested changes in the order of questions of the Vocabulary, Picture Completion, Similarities, and Comprehension Subtests. However, though questions were misordered for the present sample as a result of presenting them in the order prescribed in the test manual, the misordering was not great enough to seriously affect subtest scores or the interpretation of intratest scatter.     

Statistically significant differences between subtest scores on the test of reading comprehension

The authors contend that erroneous conclusions concerning intraindividual strengths and weaknesses may result when comparing scaled scores on subtests of The Test of Reading Comprehension. Examination of scaled scores may seem to indicate that a given student has performed better on one subtest than on another when, in reality, the difference between the two scores is not statistically significant. The authors present a table in which statistically significant differences between subtest scaled scores are identified. Use of the table enables more precise determination of intraindividual strengths and weaknesses.     

Self-esteem scores among deaf college students: an examination of gender and parents' hearing status and signing ability

Overall, research studies of self-esteem and deafness yield inconsistent findings. Some studies indicate a higher incidence of low self-esteem among deaf individuals than among hearing individuals (Bat-Chava, 1994; Mulcahy, 1998; Schlesinger, 2000). Other findings suggest that one must examine this complex phenomenon more closely to understand how deafness influences self-concept and self-esteem (Bat-Chava, 2000; Emerton, 1998; Foster, 1998; Munoz-Baell & Ruiz, 2000; Stone, 1998). This study asked whether self-esteem scores are significantly different among deaf college students compared across groups based on gender and parents' hearing status and signing ability. The construct of self-esteem was measured by the Rosenberg Self-Esteem Scale, administered using an American Sign Language-translated videotape. Results revealed that gender, age, and the interaction of parent by gender were nonsignificant. However, respondents who had at least one deaf parent and signed scored significantly higher than those with hearing parents who could not sign and those with hearing parents who could sign. Overall, self-esteem scores for all respondents were high. Implications for further study are discussed.     

An examination of the research and training needs in the field of deaf education

THE NATIONAL CENTER on Low-Incidence Disabilities conducted a needs assessment of the research and training needs in the field of deaf education. A total of 331 professionals, parents, administrators, and university faculty responded to the survey. Overall, respondents indicated that the number-one priority was to educate administrators about services that are appropriate for students who are deaf or hard of hearing. The second most important concern was how to work within the education system to change it. The third priority was teaching reading strategies. Additional priorities are reported for all respondents, as well as comparisons among the different respondent groups. Implications of the results are presented.     

Convergence of deaf children's sociometric scores and teachers' behavioral ratings

Twenty-four deaf children judged each other, using a standard sociometric technique, and were rated by their teachers. The correlations between the two sources at four assessment periods replicated previous findings of substantial convergence of teachers' behavioral ratings and children's sociometric scores, thereby extending this relationship to the population of language-impaired deaf children in residential school settings.     

Test-taking skills: a missing component of deaf students' curriculum

Often, conclusions about what students have learned in school are based on their performance on standardized or informal tests. For several reasons, these tests may not accurately reflect deaf students' learning. The author discusses the limitations of tests and other "products" administered to students during or after reading that are interpreted as reflecting comprehension of what is read. The author also reviews documented differences in test-taking abilities of deaf and hearing students, and describes specific compensatory test-taking strategies used by deaf readers. A rationale is provided for including a formal test-taking skills component in the curriculum for deaf students. Finally, the author discusses portfolio assessment and contemporary societal forces working against academic testing.     

Wechsler scale performance patterns of American Indian children

Using WISC, WISC-R, and WPPSI subtest scores recategorized according to the Bannatyne scheme, the study uncovered evidence for the existence of an Indian Wechsler Scale performance pattern that is different from that found in normal and learning disabled groups. The Indian pattern finds spatial abilities more well developed than sequencing skills, which are superior to conceptual and acquired knowledge performances. The sample was composed of 142 Indian children, primarily Ojibwa (Chippewa). Supporting hypotheses addressed differences between groups of traditional Indian children and those who are more Anglo acculturated. The traditional children evidenced the Indian pattern of recategorized Wechsler subtest performance, while the more acculturated groups did not. Discussion of results centers on factors that may be related to the Indian pattern, such as cultural heritage, otitis media, and the school curriculum.     

Relationships between scores on Stanford-Binet IV and Wechsler preschool and primary scale of intelligence

A kindergarten class of 9 boys and 11 girls took the 1986 Stanford-Binet Intelligence Scale (Fourth Edition) and the Wechsler Preschool and Primary Scale of Intelligence. Of 6 correlations of total scores and subtest pairs, only the correlation of total scores was statistically significant (p<.01).     

The effect of multimedia stories about American deaf celebrities on Taiwanese hearing students' attitudes toward job opportunities for the deaf

In Taiwan, hearing people generally think deaf individuals can only do jobs requiring minimal communication. The present study was planned to help change hearing people's attitudes toward deaf people's job competence. Multimedia stories of deaf celebrities, e.g., physicians, lawyers, university presidents, professors, senior government officials, and movie stars, were developed. A multimedia computer reading program was developed in which graphic organizers, picture clues, video, and voice were integrated to make reading more exciting and pleasant. Materials were developed to be suitable for dissemination on CD. Regarding attitude change, all differences between pretests and posttests were statistically significant: Hearing students' attitudes toward deaf and hard of hearing people changed positively and significantly. It is recommended that the CD featuring American deaf celebrities be distributed to make hearing people understand deaf people's potential, and to contribute to an environment conducive to their employment in Taiwan.     

Equivalence of students' scores on timed and untimed anatomy practical examinations

Untimed examinations are popular with students because there is a perception that first impressions may be incorrect, and that difficult questions require more time for reflection. In this report, we tested the hypothesis that timed anatomy practical examinations are inherently more difficult than untimed examinations. Students in the Doctor of Physical Therapy program at Thomas Jefferson University were assessed on their understanding of anatomic relationships using multiple‐choice questions. For the class of 2012 (n = 46), students were allowed to circulate freely among 40 testing stations during the 40‐minute testing session. For the class of 2013 (n = 46), students were required to move sequentially through the 40 testing stations (one minute per item). Students in both years were given three practical examinations covering the back/upper limb, lower limb, and trunk. An identical set of questions was used for both groups of students (untimed and timed examinations). Our results indicate that there is no significant difference between student performance on untimed and timed examinations (final percent scores of 87.3 and 88.9, respectively). This result also held true for students in the top and bottom 20th percentiles of the class. Moreover, time limits did not lead to errors on even the most difficult, higher‐order questions (i.e., items with P‐values < 0.70). Thus, limiting time at testing stations during an anatomy practical examination does not adversely affect student performance.

An evaluation of traditional admission standards in predicting Kuwait University students' academic performance

The purpose of this study was to evaluate the usefulness of the traditional admission standards utilized by Kuwait University in predicting students' academic performance. It was found that the established practice of using students' score in standardized secondary school examinations and branch of study (i.e. sciences or arts emphasis) to be highly predictive of their college cumulative grade point average. Moreover, it was established that students' secondary school scores reflect intellective as well as the non-intellective factors pertaining to students' background.
