This article explores selected phonological measures, their relationships to one another, and how groups differentiated by such measures change over time during intervention. Relationships among global quantitative measures of severity (percent consonants correct), measures of variability/consistency, and measures of whole-word complexity and…

The approximate degrees of freedom Welch-James (WJ) and Brown-Forsythe (BF) procedures for testing within-subjects effects in multivariate groups by trials repeated measures designs were investigated under departures from covariance homogeneity and normality. Empirical Type I error and power rates were obtained for least-squares estimators and…

Purpose: This study was conducted to examine whether the expressive language characteristics of typically developing (TD) children learning English as a second language (ESL) have similarities to the characteristics of the English that is spoken by monolingual children with specific language impairment (SLI), and whether this could result in the…

Using Kazemi's and Stipek's (2001) framework of classroom practice, the discourse between students enrolled in a mathematics-for-teachers course and their instructor is examined. The teacher's practice is in transition from a focus on having students share multiple strategies toward a practice that additionally includes the mathematical…

Eight independent variables (differential item functioning [DIF] detection method, purification procedure, item response model, mean latent trait difference between groups, test length, DIF pattern, magnitude of DIF, and percentage of DIF items) were manipulated, and two dependent variables (Type I error and power) were assessed through…

Prior research (DeLoache, Uttal & Rosengren, 2004) has documented that 18- to 30-month-olds occasionally make scale errors: they attempt to fit their bodies into or onto miniature objects (e.g. a chair) that are far too small for them. The current study explores whether scale errors are limited to actions that directly involve the child's…

Overgeneralization occurs when a child uses the wrong word to name an object and is often observed in the early stages of word learning. We develop a method to elicit overgeneralizations in the laboratory by priming children to say the names of objects perceptually similar to known and unknown target objects. Experiment 1 examined 18 two-year-old…

Most of the spelling error analysis has been conducted in Latin orthographies and rarely conducted in other orthographies like Arabic. Two hundred and eighty-eight students in grades 1-9 participated in the study. They were presented nine lists of words to test their spelling skills. Their spelling errors were analyzed by error categories. The…

We present a summary of a study carried out with students of the first year of Bachillerato (the first of two pre-university non-obligatory secondary education courses in Spain) to determine and analyse some of their errors and difficulties in learning inequalities with the aim of improving the teaching-learning process of this topic. The study…

This article explores the attribution of linguistic resources to multilingual students in a primary school in the Netherlands. Drawing on an ethnographic study of a regular, multicultural classroom, it describes patterns of attribution emerging from observations of classroom activities and interviews with the teacher. Its focus is on the…

What syntactic patterns emerge in students' use of articles and modals? What are the reasons for these patterns? What implications do the findings of the study have for English language instruction in Botswana? Exactly 1556 essays comprising class assignments, written seminar presentations, test papers and examination scripts from 514 randomly…

The empirical performance of the technique proposed by P. O. Johnson and J. Neyman (1936) (the JN technique) and the modification of R. F. Potthoff (1964) was studied in simulated data settings. The robustness of the two JN techniques was investigated with respect to their ability to control Type I and Type III errors. Factors manipulated in the…

It is commonly believed that the quality of original cataloging on OCLC (Online Computer Library Center) and RLIN (Research Libraries Information Network) significantly differs. Past stereotypes reflected the fact that OCLC traditionally emphasized increasing the size of the database, while RLIN ascribed top priority to cataloging quality. The…

A certain group of English verbs, the ergatives, is consistently mis-passivized in Chinese-speakers' interlanguage. Comparison of the ergative construction in Chinese and English shows that they share similar properties. However, this does not seem to facilitate learning of the target English construction. Furthermore, the passive ergatives are…

A study investigated patterns of usage of French connectors (e.g., "alors,""mais,""puisque") among Chinese university students of French as a foreign language. The study arose from concern that the lack of connector usage contributed to a lack of coherence in the students' oral and written language. Subjects were 45…
