Picture book reading is widely regarded as an activity that promotes multiple aspects of children's language acquisition, including their vocabulary development. Historically, researchers interested in what underlies the link between picture book reading and vocabulary development have investigated a suite of caregiver behaviors during picture…

This article compares two methods for detecting local item dependence (LID): residual correlation examination and Rasch testlet modeling (RTM), in a commonly used 3:6 matching format and an extended matching test (EMT) format. The two formats are hypothesized to facilitate different levels of item dependency due to differences in the number of…

Adults are skilled at using language to construct/negotiate identity and to signal affiliation with others, but little is known about how these abilities develop in children. Clearly, children mirror statistical patterns in their local environment (e.g., Canadian children using "zed" instead of "zee"), but do they flexibly…

Purpose: The study aims to evaluate the readability, comprehensibility, and vocabulary knowledge of SRH educational materials available online and on paper to inform health educational material development for young adolescents. Design/methodology/approach: The study used a sequential mixed-method design. Thirty-four online and one print…

The aim of this study is to explore the relation of morphological awareness to vocabulary, word reading, and reading comprehension for middle school students in Korea. A total of 121 students (73 boys and 48 girls) in Grade 7 from two middle schools in a metropolitan city in South Korea participated in the study. The students were assessed on the…

Purpose: We examined the properties of mean length of utterance (MLU) in Czech, a morphologically complex Slavic language. We compared the scores of MLU calculated in different units and based on different sample lengths and assessed its validity against another transcript and test-based measures. Method: One hundred nine children were recorded…

Research Findings: The present study examined the relation between socioeconomic status (SES) and Chinese children's development of English as a second language in Hong Kong, and whether the home literacy environment (HLE) was an important mediator. Participants were 237 children (110 girls, M[subscript age] = 47.38 months, SD[subscript age] =…

In spite of the proliferation of research studies on vocabulary knowledge, investigating the relationship between self-regulation, vocabulary size, and collocational knowledge among English as a Foreign Language (EFL) learners has received scant attention. The current study aimed to investigate whether vocabulary and collocation size can explain…

Despite extensive research on assessing collocational knowledge, valid measures of academic collocations remain elusive. With the present study, we employ an argument-based approach to validate two Academic Collocation Tests (ACTs) that assess the ability to recognize and produce academic collocations (i.e., two-word units such as "key…

Based on theories on vocabulary knowledge, grammar knowledge, and reading comprehension subcomponents, ten attributes/subskills were defined for 50 items from relevant subtests of TEM4 (Band Four of Test for English Majors in China). Cognitive diagnosis was conducted on the TEM4 data of the randomly sampled 2285 examinees (roughly at the B2 level)…

Bilingual children's total vocabulary in each of their languages is often smaller than that of monolinguals. In their seminal study, Bialystok et al. (2010. 'Receptive vocabulary differences in monolingual and bilingual children.' "Bilingualism: Language and Cognition" 13 (4): 525-531) divided children's vocabulary into 'home' and…

The present study presents an experiment in which online acronyms, formed from common fixed phrases or formulaic expressions, and in common usage in English medium computer-based communication, were presented to Korean university-level learners placed into either a control group or treatment group which was given instruction into the expansions…

Early linguistic environment has shown an impact on children's later language development, particularly, child directed speech has been associated with providing children with linguistic input from which to look for regularities and patterns, and boosting children to produce utterances beyond their current competence. This article aims to examine…

The purpose of this study was to compare the functioning of five restrictive CDMs, including DINA, DINO, A-CDM, LLM, and RRUM, against the G-DINA model to identify the best-fitting CDM which can better explain the interaction underlying the attributes of the reading comprehension section of an Iranian high-stakes language proficiency test. To this…

This study aims to determine the cognitive structures of students at different educational levels (8th grade and 12th grade) related to acid-base chemistry. The research was designed as a case study and structured in two stages. The first stage analyzed concepts related to acid-base chemistry and their direction and strength in students' knowledge…
