This study introduces the first Arabic Vocabulary Levels Test (Arabic-VLT), created for foreign learners of Arabic. We present compelling evidence to substantiate its validity and reliability. The Arabic-VLT was developed according to five levels, beginning with the most frequently used words (Level 1) to the least frequently used ones (Level 5),…

This academic article provides the essential steps for designing an effective English questionnaire in social science research, with a focus on ensuring clarity, cultural sensitivity and ethical integrity. Developed from key insights from related studies, it outlines potential practice in questionnaire design, item development and the importance…

The primary purpose of this study was to provide preliminary validity evidence for a 140-item form of the Vocabulary Size Test, which is designed to measure written receptive knowledge of the first 14,000 words of English. Nineteen native speakers of English and 178 native speakers of Japanese participated in the study. Analyses based on the Rasch…

This study found that three oral discourse genres (script, picture description, and replica play narration) were able to characterize development in discourse abilities in 6 children (ages 5-7) with brain injury and 43 nondisabled children. Brain-injured children produced shorter discourse performances with more off-task talk but showed…

This study evaluated the validity of language-assessment instruments with Native American children, ages 3 to 5. Results indicated that the Preschool Language Scale-3 provides a valid assessment of the receptive and expressive language skills of 3- and 4-year-old Native-American children. However, use of this scale with 5-year-old Native Americans…

Thirty-one children (aged 6-10) with auditory processing problems completed the Staggered Spondaic Words (SSW) Test and a battery of auditory-language tests. No significant correlations were found between the SSW right competing and left competing conditions and the auditory-language tests, suggesting that these two approaches measure different…

This study evaluated 9 computer-generated measures of children's language production, based on 24 children with specific language impairment and 24 normally developing children, ages 24-50 months. Three measures possessed desirable developmental and diagnostic characteristics: mean syntactic length, total number of words, and number of different…

The scores of 11 non-handicapped kindergarten children on the Pragmatic Protocol (used in assessing language-handicapped children) were correlated with their ratings by five experienced judges on a 7-point equal-appearing interval scale of communicative competence. The concurrent validity of the Protocol and interobserver reliability were…

The study compared results of the Preschool Language Scale, administered to 214 rural and 214 suburban children in Nebraska. Both groups scored above age level, but a higher percentage of rural children failed a wide range of verbal ability and auditory comprehension items. The scale did not meet criteria for nonbiased, ecologically valid…

This study examined the temporal reliability of four quantitative measurements of linguistic behaviors in 20 preschool children observed in a naturalistic setting. Although inadequate reliability was found for the measure which used total number of words, very high reliability coefficients were obtained for the measures which used number of…

Since the numbers of foreign students aspiring to college and graduate degrees in the United States is increasing, there is a need for a reliable and valid English proficiency test which, ideally, would be neither costly nor time consuming. The purpose of this study was twofold. First, the extent to which three tests, the Michigan Test of English…

A study was undertaken to develop a partial credit scheme for scoring cloze-type questions on an English collocation test, obtain construct validity evidence for the test and the scoring scheme using the Rasch Partial Credit Model, and compare partial credit scoring with the more commonly used dichotomous scoring with the same test instrument.…

This study, involving 20 children (ages 4-11) with severe hearing impairments, affirmed the content validity of the Clark-Madison Test of Oral Language as a measure of nonwritten expressive language with hearing-impaired children. Performance comparison with hearing individuals revealed a different profile of strengths and weaknesses than did…

The Peabody Picture Vocabulary Test-Revised assesses standard American English receptive vocabulary in individuals, both handicapped and nonhandicapped, ages 2 to 40. This paper describes the test's administration, summation of data, standardization, reliability, and validity. (JDD)

This paper reviews basic social validity assessment techniques, discusses the constructs underlying direct magnitude estimation (DME), illustrates the use of DME for performing social validity evaluations of spontaneous language samples (with 3 brain-injured children, ages 10-15, and 3 controls), and discusses the relationship between subjective…
