C-Test is a gap-filling test designed to measure first and second language proficiency. Over the past four decades, researchers have shown the fit of C-Test data to parametric item response theory (IRT) models, but no study so far has shown the fit of C-Tests to nonparametric IRT models. The purpose of this study is to contribute to the ongoing…

As survey research in second language acquisition grows in popularity, the adherence to best practices associated with questionnaire quality is critical for a better understanding of factors that influence second language (L2) development. To ensure that a self-report scale targets the construct of interest and does it consistently and accurately,…

For young Spanish-speaking children entering U. S. schools, it is imperative that educators foster growth in the home language and in the language of instruction to the fullest extent possible. Monitoring language development over time is crucial for promoting language development because it allows educators to individualize student instruction.…

Artificial language learning (ALL) experiments have become an important tool in exploring principles of language and language learning. A persistent question in all of this work, however, is whether ALL engages the linguistic system and whether ALL studies are ecologically valid assessments of natural language ability. In the present study, we…

In many low- and middle-income countries, young children learn a mother tongue or indigenous language at home before entering the formal education system where they will need to understand and speak a country's official language(s). Thus, assessments of children before school age, conducted in a nation's official language, may not fully reflect a…

The "TOEFL iBT"® test presents test takers with tasks meant to simulate the tasks required of students in English-medium universities. Research establishing the validity argument for the test provides evidence for score interpretation and the use of the test for university admissions and placement. Now that the test has been operational…

In a response to an article by Cleary, the literature on C-Testing is reviewed and the influence of Klein-Bradley is noted. It is concluded that, although C-Testing may be a legitimate device of first-language testing, it lacks a theoretical basis for application with second-language learners. (12 references) (Author/LB)

In recent years, T-unit analysis has been applied in second language research to characterize the syntactic nature of linguistic input and to assess the syntactic maturity of the learners' written production. This measure has been seen to provide an objective and reliable method of determining the overall complexity of language samples. However,…

Discusses the reliability and validity of different measures of lexical richness in various language data research and computer simulations, and examines the behavior of these measures in spontaneous speech data of first language and second language children learning Dutch, aged 4 to 7, compared with their lexical abilities as measured by tests.…

Describes the development of an instrument designed to assess the language competence of second language learners by observing natural interactions in transitional bilingual classrooms. A pilot study that assessed the social language of 24 bilingual fifth-graders in a summer math program provided data for examining the instrument's reliability and…

Language Assessment Scales, LAS I, are designed for children in grades K-5. LAS I accommodates ethnic and linguistic differences and provides direct language activities taken from the popular culture of both English- and Spanish-speaking peoples. LAS I consists of two independent tests, one in English and the other in Spanish, presented largely on…

Language Assessment Scales, Level 2 (LAS II) are used to assess the linguistic proficiency of limited-English-speaking or non-English-speaking adolescents. LAS II, like its predecessor, LAS I, provides a picture of oral linguistic proficiency based on a student's performance across four linguistic subsystems: phonemic, lexical, syntactic and…
