The usage of data mining has dramatically increased over the past few years and the education sector is leveraging this field in order to analyze and gain intuitive knowledge in terms of the vast accumulated data within its confines. The primary objective of this study is to compare the results of different classification techniques such as Naïve…

Item response models typically assume that the item characteristic (step) curves follow a logistic or normal cumulative distribution function, which are strictly monotone functions of person test ability. Such assumptions can be overly-restrictive for real item response data. We propose a simple and more flexible Bayesian nonparametric IRT model…

The purpose of this study was to examine the influencing factors affecting high school students who took a college preparatory curriculum in high school, yet ended up being placed into a remedial mathematics course in college. Remedial students with a college preparatory background are an under-researched group. This study attempts to address this…

Regional Educational Laboratory Southwest partnered with the Arkansas Department of Education (ADE) to examine Arkansas's middle and high school indicators of postsecondary readiness and success, building on an earlier study of these indicators (Hester et al., 2021). Academic indicators include attaining proficiency on state achievement tests,…

Two groups of freshman students, enrolled in a Vocabulary I and Reading I courses, participated in the study. Before instruction, both groups took a recognition (vocabulary) and a production (oral reading) pre-test. Comparisons of the pre-test scores showed no significant differences between the experimental and control group in decoding skills…

The purpose of this study was to explore the ways emergent bilingual first-graders draw on multiple linguistic resources during reading assessments and the participation of their Spanish-dominant parents in those assessments, as children engaged in English and Spanish retelling tasks. Informed by a translanguaging lens, sociopsycholinguistic and…

This study investigates the role of biological age and L2 exposure on the achievement of two groups of Catalan-Spanish intermediate learners of English in secondary school (Group A, Formal Instruction (FI), N = 50; Group B, FI + CLIL, N = 50) regarding receptive and productive L2 skills as well as grammatical knowledge. Learners were matched for…

This article deals with religious discourse in modern history school textbooks in Ukraine that cover early modern times in Ukrainian history. It analyzes the place of religious discourse within national discourse, the correlation between local Ukrainian religious and more general discourse, and the representation of the relationships between…

This study aimed to investigate the effects of calibration sample size and item bank size on examinee ability estimation in computerized adaptive testing (CAT). For this purpose, a 500-item bank pre-calibrated using the three-parameter logistic model with 10,000 examinees was simulated. Calibration samples of varying sizes (150, 250, 350, 500,…

Background: It has been shown that mathematical representations can aid children's understanding of mathematical concepts but that children can sometimes have difficulty in interpreting them correctly. New advances in eye-tracking technology can help in this respect because it allows data to be gathered concerning children's focus of attention and…

Purpose: The gold standard for diagnosing childhood apraxia of speech (CAS) is expert judgment of perceptual features. The aim of this study was to identify a set of objective measures that differentiate CAS from other speech disorders. Method: Seventy-two children (4-12 years of age) diagnosed with suspected CAS by community speech-language…

The purpose of this study was to determine the effectiveness of a point-of-view video modeling intervention to teach mathematics problem-solving when working on word problems involving subtracting mixed fractions with uncommon denominators. Using a multiple-probe across students design of single-case methodology, three high school students with…

The article reports 4 experiments that explore the notion of recognition without awareness using words as the material. Previous work by Voss and associates has shown that complex visual patterns were correctly selected as targets in a 2-alternative forced-choice (2-AFC) recognition test although participants reported that they were guessing. The…

The question of whether written corrective feedback (CF) has a role to play in second language (L2) development has been controversial since Truscott (1996) published an article in "Language Learning" calling for the abandonment of the practice on theoretical, empirical and pedagogical grounds. As a result of his claims, an on-going…

In the present work, we have undertaken a proof-of-concept study to determine whether a simple upper-limb movement could be useful to accurately classify low-functioning children with autism spectrum disorder (ASD) aged 2-4. To answer this question, we developed a supervised machine-learning method to correctly discriminate 15 preschool children…
