Error analysis is the study of errors in learners' work with a view to looking for possible explanations for these errors. It is a multifaceted activity involving analysis of correct, partially correct and incorrect processes and thinking about possible remediating strategies. This paper reports on such an analysis of learner tests. The tests were…

An inconsistent database is a database that violates one or more of its integrity constraints. In reality, violations of integrity constraints arise frequently under several different circumstances. Inconsistent databases have long posed the challenge to develop suitable tools for meaningful query answering. A principled approach for querying…

Mobile learning research has been flourishing to keep pace with the rapid technological advancement that has been invading all parts of modern life. There is a shortage of such research in Oman, especially in schools. The aim of this study is to uncover mLearning employment in schools in Oman by exploring two cases. The study investigates the…

Differential item functioning (DIF) analysis is a key component in the evaluation of the fairness and validity of educational tests. Although it is often assumed that refinement of the matching criterion always provides more accurate DIF results, the actual situation proves to be more complex. To explore the effectiveness of refinement, we…

Purpose: This study examined sentence comprehension in children with specific language impairment (SLI) in a manner designed to separate the contribution of cognitive capacity from the effects of syntactic structure. Method: Nineteen children with SLI, 19 typically developing children matched for age (TD-A), and 19 younger typically developing…

This paper aims at supporting the claim that some forms of hyper-simplification, by making physics seem easy, are at risk of dangerously distorting the content as well as the process of learning physics. The paper presents examples of dangerous simplifications in the teaching of quantum physics. Then, examples of productive forms of complexity are…

The Common Core State Standards highlight the need to read--independently, closely, and proficiently--increasingly complex texts. However, they do not specify how such reading is to be done. This column provides a brief critique of text complexity and close reading and offers some concrete ideas for operationalizing these two concepts in secondary…

Performing a cognitive task while maintaining upright stance can lead to increased or reduced body sway depending on tasks and experimental conditions. Because greater sway is commonly taken to indicate loosened postural control, and vice versa, the precise impact of cognitive load on postural stability has remained unclear. In much of the large…

The traditional view of satiation is that repeated consumption produces an unavoidable decline in liking according to the quantity and recency of consumption. We challenge this deterministic view by showing that satiation is instead partially constructed in the moment based on contextual cues. More specifically, while satiation is a function of…

In this paper, we study the identification of a particular case of the 3PL model, namely when the discrimination parameters are all constant and equal to 1. We term this model, 1PL-G model. The identification analysis is performed under three different specifications. The first specification considers the abilities as unknown parameters. It is…

Background: A potential problem of low-stakes large-scale assessments such as the Programme for the International Assessment of Adult Competencies (PIAAC) is low test-taking engagement. The present study pursued two goals in order to better understand conditioning factors of test-taking disengagement: First, a model-based approach was used to…

This pilot study explored two methods of eliciting beginning readers' verbalizations of their thinking when self-monitoring oral reading: video-stimulated recall and concurrent questioning. First and second graders (N = 11) were asked to explain their thinking about repetitions, attempts to self-correct, and successful self-corrects, in order to…

This article is the first of a two-part series that explores science teachers' and their pupils' experiences of using different pedagogical approaches based on understandings of how brains learn. For this case-study research, nine science teachers were interviewed and four teachers self-selected to trial a pedagogical approach, new to them, from…

This paper explores how expectations and post-secondary education (PSE) path disruption decisions are affected by a learning process that students experience once enrolled in a PSE program. An unexpected change in grades, between high school and first year PSE program, serves as an informative signal on how well their academic performance and…

This study examines the subjects and concepts in biology perceived to be difficult to learn and teach by 759 pre-service biology teachers registered in the pedagogical formation program at Uludag University Faculty of Education in the academic year of 2005-2016, as well as the associations that word "biology" first calls to their mind.…
