The Test of German as a Foreign Language (TestDaF) plays a critical role as a standardized test of German language proficiency. Developed and administered by the Society for Academic Study Preparation and Test Development (g.a.s.t.), TestDaF was launched in 2001 and has experienced persistent annual growth, with more than 44,000 test takers in…

Over the last two decades, there has been significant debate surrounding the potential benefits, or potential harm, generated from the provision of written corrective feedback (WCF) on the writing of language learners. The majority of research in the field has been conducted within a positivist paradigm, which often adopted experimental research…

It is general practice to use rater judgments in speaking proficiency testing. However, it has been shown that raters' knowledge and experience may influence their ratings, both in terms of leniency and varied focus on different aspects of speech. The purpose of this study is to identify raters' relative responsiveness to fluency and linguistic…

Language proficiency tests have become common instruments to judge people based on their performance. Thus, the scores on language proficiency tests, such as the International English Language Testing System (IELTS) or Teaching English as a Foreign Language (TOEFL), play a crucial role in the test-takers' lives. Because of increasing demands on…

Based on the dynamic and emerging nature of language aptitude, the paper reports an empirical study investigating the relationship between multilingual learning experiences and language aptitude through comparative analyses of language aptitude between second language (L2) and third language (L3) learners. Eighty-seven Chinese students who majored…

It is commonly found that deaf and hard of hearing (DHH) students experience delayed mathematical achievement. The present study used two nonsymbolic comparison tasks to explore the basic numerical skills of DHH students. Nine prelocutive DHH students with cochlear implants and nine hearing students, matched on nonverbal IQ, visual short-term…

In the past 2 decades, there has been an increasing tendency to use scores from the "TOEFL iBT"® Speaking test for decisions regarding the certification of international graduate students as teaching assistants at North American universities. To obtain validity evidence in support of the usefulness of the speaking scores for this…

Many disadvantaged students with refractive errors, such as myopia (nearsightedness) and hyperopia (farsightedness), do not have eyeglasses, and their reduced vision may impact reading proficiency. Providing eyeglasses may increase their reading success. This article reports the findings of a study in Baltimore City in which disadvantaged second…

Making inferences about a test taker's language ability has been a concern for language testers. Defining language ability in a speaking test is made difficult because the construct involves factors within and beyond the test taker. One underlying factor is the use of strategies. This study probes test takers' strategic processes and their use in…

Alzheimer's disease (AD) is a degenerative brain disease and the most common cause of dementia, accounts for an estimated 60 percent to 80 percent of cases. AD has two subtypes: Early-onset and Late-onset Alzheimer's disease. Both types are characterized by a decline in memory, problem-solving and other cognitive skills that affect a person's…

Purpose: The study aims to explore whether finite verbal morphology is affected in children/adolescents with Down syndrome (DS), whether observed deficits in this domain are indicative of a delayed or deviant development, and whether they are due to phonetic/phonological problems or deficits in phonological short-term memory. Method: An…

Assessment has an important role in education and it has a critical role in the teaching process. Through appropriate assessment, teachers can classify and grade their students, give feedback and structure their teaching accordingly. Recently, educators and scientists have been becoming more interested in the requirements of assessment procedures…

The disproportionality of culturally and linguistically diverse learners in exceptional education is an ongoing issue (Bernal, 2002; Ford, 2012). One of these special populations is that of English learners (ELs), who are overrepresented in special education programs and underrepresented in gifted and talented programs (Ford, 2012).The extant…

Knowledge tracing is a popular and successful approach to modeling student learning. In this paper we investigate whether the addition of neuroimaging observations to a knowledge tracing model enables accurate prediction of memory performance in held-out data. We propose a Hidden Markov Model of memory acquisition related to Bayesian Knowledge…

The increasing representation of young language-minority students in school settings around the world and recent insights into multilingualism as a potential resource for language learning and development call for acritical study of theoretical and practical implications for the field of language teaching and assessment. Relatively little…
