A college mathematics placement test with 25 basic algebra items and 15 calculus readiness items was administered to 1572 high school seniors, and first college mathematics course grades were obtained for 319 of these students. Test results indicated that more than two thirds of the high school graduates were not college ready, and the test…

Self-regulation has become a widely discussed subject in education as it facilitates learners' ability to master their own learning. The purpose of the present study is to examine the psychometric properties of self-regulation in second language learning via Rasch measurement. A total of 528 high-school students from an East Asian country…

Prepared for school district and education leaders, "Checking In" is the first in the "Equity in Motion" series, which scrutinizes how issues of equity are translating into the daily activities of schools and educators. Nearly every state has adopted new, more rigorous standards for college and career readiness over the past…

The concept of affordances originating in Gibson's work (Gibson, 1977) is gaining ground in multilingualism studies (cf. Aronin and Singleton, 2010; Singleton and Aronin, 2007; Dewaele, 2010). Nevertheless, studies investigating affordances in respect of teaching, learning or using languages are still somewhat rare and tend to treat isolated…

Being able to measure the level of proficiency in literacy and numeracy skills, and any changes in the level of skills, is important for getting a sense of how well language, literacy and numeracy programs are working. Among the tools used to measure language, literacy and numeracy proficiency in Australia are the Adult Literacy and Life Skills…

Background: Children's speech sound development is assessed by comparing speech production with the typical development of speech sounds based on a child's age and developmental profile. One widely used method of sampling is to elicit a single-word sample along with connected speech. Words produced spontaneously rather than imitated may give a…

Working memory capacity, our ability to manage incoming information for processing purposes, predicts achievement on a wide range of intellectual abilities. Three randomized experiments (N = 310) tested the effectiveness of a brief psychological intervention designed to boost working memory efficiency (i.e., state working memory capacity) by…

This research aims to provide insight for web form design for older users. The effects of task complexity and information structure of web forms on older users' performance were examined. Forty-eight older participants with abundant computer and web experience were recruited. The results showed significant differences in task time and error rate…

In this study, we used Rasch model analyses to examine (1) the unidimensionality of the alphabet knowledge construct and (2) the relative difficulty of different alphabet knowledge tasks (uppercase letter recognition, names, and sounds, and lowercase letter names) within a sample of preschoolers (n=335). Rasch analysis showed that the four…

This study investigated the effects of four instructional methods on cognitive load, propositional knowledge, and conceptual understanding of statistics, for low prior knowledge students and for high prior knowledge students. The instructional methods were (1) a reading-only control condition, (2) answering open-ended questions, (3) answering…

Studies of supervised Categorization have demonstrated limited Categorization performance in participants with autism spectrum disorders (ASD), however little research has been conducted regarding unsupervised Categorization in this population. This study explored unsupervised Categorization using two stimulus sets that differed in their…

Responses to items from an intelligence test may be fast or slow. The research issue dealt with in this paper is whether the intelligence involved in fast correct responses differs in nature from the intelligence involved in slow correct responses. There are two questions related to this issue: 1. Are the processes involved different? 2. Are the…

The aim of the study was to compare the difficulty of relational concepts among participants with and without intellectual disability. The French versions of the Boehm Tests of Basic Concepts Third Edition (Preschool and Kindergarten to 2nd grade) were administered to three groups of 47 participants individually matched on their total raw score on…

Much debate surrounds the issue of whether allowing candidates to listen to recordings twice is more desirable in language tests than offering just one opportunity. Using regression models, this study investigates, analyses and interconnects both item difficulty and stimulus length in relation to the frequency of stimulus presentation and its…

The constructs of complexity, accuracy and fluency (CAF) have been used extensively to investigate learner performance on second language tasks. However, a serious concern is that the variables used to measure these constructs are sometimes used conventionally without any empirical justification. It is crucial for researchers to understand how…
