Estimating student proficiency is an important task for computer based learning systems. We compare a family of IRT-based proficiency estimation methods to Deep Knowledge Tracing (DKT), a recently proposed recurrent neural network model with promising initial results. We evaluate how well each model predicts a student's future response given…

Research in literature reports the importance of L2 vocabulary and syntactic knowledge on the learners' reading comprehension. In this regard, the current study investigated the role of vocabulary knowledge that is disunited into depth and breadth dimensions and syntactic knowledge in the reading comprehension scores of an advanced cohort of…

A significant amount of research effort has been put into finding variables that can identify students at risk based on activity records available in learning management systems (LMS). These variables often depend on the context, for example, the course structure, how the activities are assessed or whether the course is entirely online or a…

Researchers studying parent-child reminiscing in the preschool years have often focused on parents' and children's elaborative talk (i.e., provision of unique details). The current study proposes a novel conceptualization of parent-child reminiscing narratives by examining 4 levels of abstraction (i.e., a continuum of literal to inferential…

Children with autism spectrum disorder (ASD) vary greatly in social functioning, and in turn, long-term relational and academic outcomes. Responsive parenting which follows a child's lead and focus of attention is predictive of language and social gains for children with or without developmental risk. The present study prospectively assessed 176…

To draw informed conclusions from research studies, research consumers need full and accurate descriptions of study methods and procedures. Preregistration has been proposed as a means to clarify reporting of research methods and procedures, with the goal of reducing bias in research. However, preregistration has been applied primarily to research…

New approaches to support the early learning for young Indigenous children are important to government policies across Australia. This study explores whether the Abecedarian Approach Australia (3a) intervention, with strong cultural adaptations, can boost young Aboriginal children's early language and learning skills, prior to preschool.…

Researchers and practitioners have questioned whether scoring procedures used with curriculum-based measures of writing (CBM-W) capture growth in complexity of writing. We analyzed data from six independent samples to examine two potential scoring metrics for picture word CBM-W (PW), a sentence-level CBM task. Correct word sequences per response…

This study assessed the extent to which executive functions (EF), according to their factor structure in 5-year-olds (N = 244), influenced early quantity-number competencies, arithmetic fluency, and mathematics school achievement throughout first and second grades. A confirmatory factor analysis resulted in updating as a first, and inhibition and…

Metaphor development in conjunction with verbal intelligence and linguistic competence in middle childhood and at the transition to early adolescence was investigated. 298 individuals between seven and ten years (chronological age) who attended grades two-four (mental age) were tested for metaphor processing by the Metaphoric Triads Task, for…

Examining how students' epistemic beliefs (EB) influence their cognition is central to EB research. Recently, the relation between students' EB and their motivation has gained attention. In the present study, we investigate the development of the relationship between students' EB and their achievement goals (AG) over grades 5-11. Previous studies…

Objective: The present study examined whether executive functions (EFs) and sleep problems operate together to predict four attention-deficit/hyperactivity disorder (ADHD) symptom domains. Methods: A sample of 306 college students completed ratings of sleep quality, EFs, and ADHD symptoms from January to December 2014. Simultaneous multiple…

The purpose of this study was to validate a new inventory designed to measure epistemic beliefs concerning the justification of knowledge claims encountered on the Internet. Confirmatory factor analysis of the scores of 394 preservice teachers showed that a three-factor model including justification by authority, justification by multiple sources,…

Purpose: The main goals were to determine the incidence of preadoption breakdown in Portugal, describe preadoptive parents' reasons for ending placement, compare intact/disrupted placements, and identify adoption disruption risk and protective factors. Method: A matched design involving a case file analysis of 71 disrupted and 71 intact…

Spelling accuracy and time course was investigated in a sample of 100 Norwegian 6th grade students completing a standardized spelling-to-dictation task. Students responded by keyboard with accurate recordings of response-onset latency (RT) and inter-keypress interval (IKI). We determined effects of a number of child-level cognitive ability…
