Teachers' ability to accurately judge difficulties of mathematical tasks is an essential aspect of their diagnostic competencies. Although research has suggested that pedagogical content knowledge (PCK) is positively correlated with the accuracy of diagnostic judgments, experimental studies have not been conducted to investigate how PCK affects…

Students' issues dealing with reflection tasks, especially with inclined mirror lines, are widely known. Previous research conducted with primary school students mainly focussed on task difficulty and students' outcomes, especially their errors of reflection. Little is known about which not obviously sustainable understanding of reflection leads…

Facilitated identification of predictable words during online reading has been attributed to the generation of predictions about upcoming words. But highly predictable words are relatively infrequent in natural texts, raising questions about the utility and ubiquity of anticipatory prediction strategies. This study investigated the contribution of…

Spelling poses a challenge to Arabic-speaking learners due to the complexity of the morphological and orthographic systems in Arabic. Arabic morphology has been argued to play a critical role in spelling since its morphological operations are built on a system consisting of a root that is interlocking into different patterns of vowels to form…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

An onto-semiotic analysis of the mathematical connections established by one in-service mathematics teachers and university students when solving a problem about launching a projectile using the derivative was carried out. Theoretically, this research was based on the articulation between the Extended Theory of Mathematical Connections and the…

The More A-More B intuitive rule has become a research hotspot in the field of mathematical education in recent years. The intuitive rule of More A-More B is often reflected in students' responses to comparison tasks. In such tasks, students are asked to compare 2 objects that differ in a certain salient quantity A (where A[subscript 1] >…

The study focuses on the effect of the lexical-syntactic structure on the patterns of errors by Arab first graders in tasks involving reading two-digit number and writing two-digit numbers to dictation. Children made few change or omission errors, indicating that they had little problem with the lexical aspects of the counting system. However,…

Many modern anatomy curricula teach histology using virtual microscopes, where students inspect tissue slices in a computer program (e.g. a web browser). However, the educational data mining (EDM) potential of these virtual microscopes remains under-utilized. In this paper, we use EDM techniques to investigate three research questions on a virtual…

Due to their abstract nature, representation of mathematical concepts through different registers favors their understanding. In the case of ''sequences and regularities'', it becomes propitious the exploration of different registers of representation in the institution of topics, such as term, order, formation law, and generating expression.…

This study examined Spanish spelling errors among 166 native Spanish-speaking students from Kindergarten to Grade 3 based on a spelling-to-diction task. Fifteen types of spelling errors were analyzed in a latent class analysis. Results suggested three phases of spellers: Phase 1 students had a high chance of committing almost all types of errors.…

We conducted a skills analysis on written expression curriculum-based measurement (WE-CBM) tasks completed by 117 second-grade students. As part of the skills analysis, we scored two WE-CBM tasks (i.e., narrative and expository) for correct and incorrect writing sequences, common writing errors, and sentence structures. Although a majority of…

Reading monitoring is poorly explored, but it may have an impact on well-documented reading comprehension difficulties in autism. This study explores reading monitoring through the impact of instructions and different error types on reading behavior. Individuals with autism and matched controls read correct sentences and sentences containing…

Purpose: Using a blocked cyclic picture-naming task, we compared accuracy and error patterns across languages for Spanish-English bilingual children with and without developmental language disorder (DLD). Method: Pictured stimuli were manipulated for semantic similarity across two (Same and Mixed) category contexts. Children's productions were…

Understanding discourse connectives is an important step to achieving effective verbal communication. Yet, the ability of adult native speakers to understand the broad range of connectives found in most Indo-European languages has seldom been assessed. In this article we demonstrate that some adults have difficulties recognizing correct and…
