We encounter variables with little variation often in educational data mining (EDM) due to the demographics of higher education and the questions we ask. Yet, little work has examined how to analyze such data. Therefore, we conducted a simulation study using logistic regression, penalized regression, and random forest. We systematically varied the…

To understand misconceptions with rational numbers (i.e., fractions, decimals, and percentages), we administered an assessment of rational numbers to 331 undergraduate students from a 4-year university. The assessment included 41 items categorized as measuring foundational understanding, calculations, or word problems. We coded each student's…

Developing an understanding of fractions is critical as a significant predictor for the learning progression of advanced domains; however, students face significant challenges in learning fractions because of their unique properties. To systematically approach remediation, this study examined the common error patterns committed by middle-school…

Students of English as a Foreign Language (EFL) are expected to master the fundamental of grammar so they can produce good essays. However, despite having learned English at the secondary or university level, students tend to make many grammatical errors in their writing. This study presents the grammatical errors made by college EFL students in…

Purpose: This scoping review aims to identify and analyze the nature of the spelling errors produced by children with developmental language disorder (DLD) across different orthographies. Building on a previous meta-analysis identifying the extent of the spelling difficulties of children with DLD, the review extends our understanding of the nature…

The purpose of this descriptive study is to analyze the writings of fourth-grade Turkish-speaking students with low vision in terms of legibility and spelling errors. The study is a general survey design and used the criterion sampling method. The study group consisted of 32 students with low vision. A Multidimensional Legibility Scale was used to…

The aim of this study is to obtain information about students' definitions, mistakes, misconceptions, and van Hiele geometry thinking levels by using the definitions of 4th grade students for geometric shapes of rectangle, square, isosceles triangle, equilateral triangle, and scalene triangle. The study was carried out with 156 primary school 4th…

Background: Imprecise articulation has a negative impact on speech intelligibility. Therefore, treatment of articulation is clinically relevant in patients with dysarthria. In order to be effective and according to the principles of motor learning, articulation therapy needs to be intensive, well organized, with adequate feedback and requires…

Background and aims: Children with autism spectrum disorders (ASD) have been found to exhibit difficulties in "wh"-question production. It is unclear whether these difficulties are pragmatic or syntactic in nature. The current study used a question elicitation task to assess the production of subject and object "wh"-questions…

In contrast to simple feedback, which provides students with the correct answer, elaborated feedback provides an explanation of the correct answer with respect to the student's error. Elaborated feedback is thus a challenge for AI in education systems because it requires dynamic explanations, which traditionally require logical reasoning and…

Background: Engineering students commonly learn domain knowledge by engaging with visual representations of it. However, at times they have trouble accessing information from these representations due to the way information is encoded in features of the representation. Purpose: To describe how students engage with representation features, we…

Students of introductory economics are often able to predict changes in equilibrium price correctly on standardized assessments, but make consistent errors in predicting changes in equilibrium quantity. To examine the reasons for this pattern, the authors collected open-ended explanations written by students and categorized their reasoning using a…

The present study systematically reviewed research that was conducted to analyze the errors within the written expressions of individuals learning Turkish as a foreign language. The sample of the study consisted of 16 articles that were identified through the review of literature. The articles that focused on the written expression errors made by…

Error analysis consumes much of the focus in introductory physics labs. Catastrophic cancellation is a spike in error that occurs when subtracting two measurements of roughly equal magnitude. Often termed "loss of significance" or "subtractive cancellation," this effect can easily relegate experimental results to utter…

Imprecise articulation is the major issue reported in various types of dysarthria. Detection of articulation errors can help in diagnosis. The cues derived from both the burst and the formant transitions contribute to the discrimination of place of articulation of stops. It is believed that any acoustic deviations in stops due to articulation…
