Background: Speech-sound development in preschoolers with unilateral cleft lip and palate (UCLP) as a group is delayed/disordered, and obstruents comprise the most vulnerable sound class. Aims: To evaluate the development of obstruent correctness (PCC-obs) and error types (cleft speech characteristics (CSCs) and developmental speech…

This study investigates the English spelling of students in grades 2 through 8 in Mainland China. A review of spelling and cross-linguistic research in spelling is presented. The orthographic development of 273 students was assessed "with validated spelling inventories" (Sterbinsky, 2007) to sample developmental features across three…

This study aims to examine the developmental changes in young children's perception. A matching completion task consisting of three geometric figures and one bird-like figure were completed by children 3-5 years of age ("N" = 99). The rotation effect, in which the correct response decreased with orientation (45°, 90° 135°, and 180°), was…

"Specific Mathematics Assessment that Reveal Thinking" (abbreviated as "smart tests") provide an on-line formative assessment of middle years students. They aim to put information from research on students' understanding directly into the hands of teachers, by providing quick automated diagnosis of learning for all students in…

The acquisition of systematic patterns and exceptions in different languages can be readily examined using the causative construction. Persian allows four types of causative structures, including one productive multiword structure (i.e. the light verb construction). In this study, we examine the development of all four structures in Persian child…

Working memory (WM) as the ability to temporarily maintain and manipulate various kinds of information is known to be affected by proactive interference (PI) from previously relevant contents, but studies on developmental changes in the susceptibility to PI are scarce. In the present study, we investigated life span development of item-specific…

Two studies of children learning to read (one before the introduction of phonics instruction, the other while phonics instruction was being given) found that error-target similarity increased with reading attainment. This suggests that while reading aloud, considerable knowledge of spelling develops independently of explicit use of phonics. (CMG)

Evaluation of the speech of five Dutch-speaking adolescent girls with Down's syndrome found that speech errors tended to be identical to the error patterns in young normal children supporting the view that misarticulations in Down's syndrome subjects are mainly the result of a delay in speech development.

The present study examines 20 writing samples in English and Spanish selected from portfolios of first grade children at a bilingual school in Ecuador. Based on earlier findings that paragraphs composed in English and Spanish by children, adolescents and adults are different (Lux & Grabe, 1991; Montano-Harmon, 1991; Reid, 1990; Reppen &…

Tested the hypothesis that young children's tendency to draw horizontal or vertical objects perpendicularly to an oblique surface reflects their preference for perpendicular drawings as conceptually correct depictions. (Author/RH)

The reports of research in this monograph reflect 18 years of observation of the behaviors of children learning to read in New Zealand schools. The first section of the monograph urges teachers to look more closely at language behaviors in their classrooms to see how children go about the tasks set before them. The second section reports on…

This volume of the 30th annual proceedings of the International Group for the Psychology of Mathematics Education conference presents: plenary panel papers; research forum papers; short oral communication papers; and poster presentation papers from the meeting. Information relating to discussion groups and working sessions is also provided.…
