Research investigating corpora of English learners' language raises new questions about how syntactic complexity is defined theoretically and operationally for second language (L2) writing assessment. I show that syntactic complexity is important in construct definitions and L2 writing rating scales as well as in L2 writing research. I describe…

Automated essay scoring can produce reliable scores that are highly correlated with human scores, but is limited in its evaluation of content and other higher-order aspects of writing. The increased use of automated essay scoring in high-stakes testing underscores the need for human scoring that is focused on higher-order aspects of writing. This…

This paper compares two alternative scoring methods--multiple regression and classification trees--for an automated speech scoring system used in a practice environment. The two methods were evaluated on two criteria: construct representation and empirical performance in predicting human scores. The empirical performance of the two scoring models…

Automated scoring has the potential to dramatically reduce the time and costs associated with the assessment of complex skills such as writing, but its use must be validated against a variety of criteria for it to be accepted by test users and stakeholders. This study approaches validity by comparing human and automated scores on responses to…

This study tracked gender differential item functioning (DIF) on the English subtest of the Korean College Scholastic Aptitude Test (KCSAT) over a nine-year period across three data points, using both the Mantel-Haenszel (MH) and item response theory likelihood ratio (IRT-LR) procedures. Further, the study identified two factors (i.e. reading…

This paper assesses the performance of a vocabulary test designed to measure second language productive vocabulary knowledge.The test, Lex30, uses a word association task to elicit vocabulary, and uses word frequency data to measure the vocabulary produced. Here we report firstly on the reliability of the test as measured by a test-retest study, a…

This paper presents evidence that supports the valid use of scores from fully automatic tests of spoken language ability to indicate a person's effectiveness in spoken communication. The paper reviews the constructs, scoring, and the concurrent validity evidence of "facility-in-L2" tests, a family of automated spoken language tests in Spanish,…

Although the Word Associates Format (WAF) is becoming more frequently used as a depth-of-knowledge measure, relatively little validation has been carried out on it. This report of two validation studies tackles various important WAF issues yet to be satisfactorily resolved. Study 1 conducted introspective interviews regarding students' WAF…

This study investigated the validity of four theoretically motivated traits of writing ability across English and Korean, based on elementary school students' responses to letter- and story-writing tasks. Their responses were scored analytically and analyzed using confirmatory factor analysis. The findings include the following. A model of writing…

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…

In order to facilitate the interpretation of test scores from the TOEIC[R] "Bridge" as a measure of English language proficiency, one form of the test was administered to more than 6000 test takers in three South American countries--Colombia, Chile and Ecuador. The appropriateness of the TOEIC "Bridge" test as a measure of…

This paper describes the development and validation of the Cognate Awareness Test (CAT), which measures cognate awareness in Spanish-speaking English Language Learners (ELLs) in fourth and fifth grade. An investigation of differential performance on the two subtests of the CAT (cognates and noncognates) provides evidence that the instrument is…

This study examined the effects of training on peer assessment and comments provided regarding oral presentations in EFL (English as a Foreign Language) classrooms. In Study 1, both the treatment and control groups received instruction on skill aspects, but only the treatment group was given an additional 40-minute training on how to rate…

The present study utilized both the IRT-LR (item response theory likelihood ratio) and a series of CFA (confirmatory factor analysis) multi-sample analyses to systematically examine the relationships between DIF (differential item functioning) and DTF (differential test functioning) with a random sample of 15 000 Korean examinees. Specifically,…

Results from the Ontario Secondary School Literacy Test (OSSLT) indicate that English as a Second Language (ESL) and English Literacy Development (ELD) students have comparatively low success and high deferral rates. This study examined the 2002 and 2003 OSSLT test performances of ESL/ELD and non-ESL/ELD students in order to identify and…
