Purpose: We assessed the potential direct and indirect (mediated) influences of 4 cognitive mechanisms we believe are theoretically relevant to canonical and noncanonical sentence comprehension of school-age children with and without developmental language disorder (DLD). Method: One hundred seventeen children with DLD and 117 propensity-matched…

In many evolving systems, inputs can be derived from both human observations and physical sensors. Additionally, many computation and analysis tasks can be performed by either human beings or artificial intelligence (AI) applications. For example, weather prediction, emergency event response, assistive technology for various human sensory and…

The present study investigated (a) whether the perceived cognitive load was different when geometry problems with various levels of configuration comprehension were solved and (b) whether eye movements in comprehending geometry problems showed sources of cognitive loads. In the first investigation, three characteristics of geometry configurations…

Primary literature is our main mode of communication in the sciences. As such, it is important for our undergraduates in the discipline to learn how to read primary literature. Incorporating primary literature into undergraduate science courses is often difficult because students are unprepared to comprehend primary articles. Learning to read and…

Early measures of mathematics skill and development have focused on early numeracy skills like counting, number identification, and sequencing of numbers. This study attempted to expand early mathematics assessment. Six new measures of early mathematics skill competence were developed and evaluated. Four existing measures also were examined.…

The results presented here derive from a longitudinal study of Swedish upper secondary science students' (16-19 years of age) developing understanding of key chemical concepts. The informants were 18 students from two different schools. The aim of the present study was to investigate the mental models of matter at the particulate level that…

A previous study by Begg and Pavio found that subjects presented with concrete sentences were able to detect subsequent changes in meaning better than changes in wording. In contrast, with abstract sentences, wording changes were detected with greater facility than were changes in meaning. The present study assesses the effect of comprehension on…

This study of 73 children sought to determine if children's perceptual comprehension of numerals is higher when they are shown symmetrical rather than asymmetrical arrangements of pegs, and if comprehension scores related to age, sex, and/or social class. The main hypothesis was rejected but some age and class differences were found. (SJL)

This paper presents a study of age differences in children's plan interpretations, interpretations of the interrelationship between actions, goals and outcomes. It is suggested that developmental differences exist which affect children's ability to recognize the necessity for internal and external consistency before labeling behaviors as…

This document contains the fourth volume of the proceedings of the 30th Conference of the International Group for the Psychology of Mathematics Education. Conference presentations are centered around the theme "Mathematics at the Centre." This volume features 59 research reports by presenters with last names beginning between Kun and…
