Clustering is one of the most common data mining tasks, used frequently for data organization and analysis in various application domains. Traditional machine learning approaches to clustering are fully automated and unsupervised where class labels are unknown a priori. In real application domains, however, some "weak" form of side…

Background: Nonword repetition (NWR) involves the ability to perceive, store, recall and reproduce phonological sequences. These same abilities play a role in word and morpheme learning. Cross-linguistic studies of performance on NWR tasks, word learning, and morpheme learning yield patterns of increased performance on all three tasks as a…

The development of executive functions in the preschool years is not fully understood. Although there exists a large body of research investigating the maturation of executive functioning in school-aged children, little is known about the emergence of such skills, in particular inhibition, among preschool-aged children. Understanding developmental…

This paper presents a tool for drawing dynamic geometric figures by understanding the texts of geometry problems. With the tool, teachers and students can construct dynamic geometric figures on a web page by inputting a geometry problem in natural language. First we need to build the knowledge base for understanding geometry problems. With the…

An area that has recently attracted increasing attention is providing feedback on learners' writing accuracy through the Internet. However, research in this area has largely focused on synchronous communication, i.e., chatting, with fewer studies assessing asynchronous technologies, i.e., e-mailing. Therefore, this study investigates the…

In the Southwest, politicians, legislature, and voters have devised and instituted a plan originally known as House Bill 2732, voted into law A.R.S.15-701§ A (2) & (3), which declares that all third grade students, beginning in the 2013-2014 school year, must receive a score that demonstrates their competency as approaching or above their…

The simple view of reading admits two components in accounting for individual differences in reading comprehension: a print-dependent component related to decoding and word identification, and a print-independent one related to oral language comprehension. It has been debated whether word or nonword reading is a better index of the print-dependent…

The study challenged the current practices in cognitive load measurement involving complex problem solving by manipulating the presence of pictures in multiple rule-based problem-solving situations and examining the cognitive load resulting from both off-line and online measures associated with complex problem solving. Forty-eight participants…

The purpose of this quantitative research study was to investigate the use of rote learning in basic skills of mathematics and spelling of 12 high school students, from a career and technical high school, in an effort to learn if the pedagogy of rote fits in the frameworks of today's education. The study compared the accuracy of…

Cognitive diagnostic assessment (CDA) is a new theoretical framework for psychological and educational testing that is designed to provide detailed information about examinees' strengths and weaknesses in specific knowledge structures and processing skills. During the last three decades, more than a dozen psychometric models have been developed…

Cross-lingual tests are assessment instruments created in one language and adapted for use with another language group. Practitioners and researchers use cross-lingual tests for various descriptive, analytical and selection purposes both in comparative studies across nations and within countries marked by linguistic diversity (Hambleton, 2005).…

The quality of measurement systems used in almost all natural sciences other than behavior analysis is usually evaluated through calibration study rather than relying on interobserver agreement. We demonstrated some of the basic features of calibration using observer-measured rates of free-operant responding from 10 scripted 10-min calibration…

Modern socio-cognitive and meaning-oriented approaches to foreign language teaching emphasize the role of learner autonomy, which involves being aware of and responsible for one's own ways of learning as well as the utilization of one's own strengths and work on weaknesses (van Lier 1996). Allowing learners to perform self-assessment can provide a…

This study presents an efficient approach to personalized mispronunciation detection of Taiwanese-accented English. The main goal of this study was to detect frequently occurring mispronunciation patterns of Taiwanese-accented English instead of scoring English pronunciations directly. The proposed approach quickly identifies personalized…

Evidence suggests that children living in areas designated as socially disadvantaged may be at risk for literacy difficulties. The Simple View of Reading (Gough & Tunmer, 1986; Hoover &Gough, 1986) is a theoretical model that sets out to describe the processes that children need to develop to become proficient readers, that is word…
