Problem-solving is the essence of mathematics and is the main goal in learning mathematics. Many students did not have good problem-solving skills based on the field observations. The problems grew up because the students were not used to solving the problems and the problem-solving stages. They did not include issues with high complexity, such as…

How dyslexia students solve number operations is still challenging to unravel. This study aimed at revealing the types of errors conveyed by a dyslexic student in performing fractional operations on mathematical tasks that combined non-verbal text (symbols and pictures) and verbal text. The data were collected using a task-based interview with a…

This study investigated common student errors and underlying difficulties of two groups of Chinese middle school students in an introductory Python programming course using data in the automated assessment tool (AAT) Mulberry. One group of students was from a typical middle school while the other group was from a high-ability middle school. By…

As part of a larger project, this study explores Vietnamese college students' use and concepts of cohesive devices in writing. Cohesion is a crucial element that ties components of a text together. Although the use of cohesive devices in L2 writing has been investigated by a large body of research, there is no such study exploring the effects of…

We need a critical mathematics. Our ability to enact social change through teaching mathematics and through critical research in mathematics education is severely limited by the canon of mathematical knowledge and the ideology that declares mathematical knowledge as certain. In this dissertation I extend Carspecken's critical action theory to…

Decades of memory research have demonstrated a dire need for effective methods of correcting misinformation, particularly once it has been encoded. However, much of this research has exposed participants to misinformation first then provided a correction, and used indirect memory questions. Using a misinformation effect (ME) paradigm, in which…

This study examined factors related to repetitive errors in people with autism spectrum disorder (ASD) from the perspective of output monitoring and memory for rules. Previous studies have suggested that output monitoring errors are associated with repetition errors. Moreover, people with ASD have a reduced memory for rules, which could result in…

The aim of this study was to evaluate the technical procedural iatrogenic errors, especially to determine the frequency of dental perforation made by undergraduate students in Sofia, Faculty of Dentistry, Bulgaria, in the school years of 2014/2015 and 2015/2016. The assessment was by examination of periapical radiographs of completed…

This article explores the amount of equating error at a passing score when equating scores from exams with small samples sizes. This article focuses on equating using classical test theory methods of Tucker linear, Levine linear, frequency estimation, and chained equipercentile equating. Both simulation and real data studies were used in the…

Trend scoring is often used in large-scale assessments to monitor for rater drift when the same constructed response items are administered in multiple test administrations. In trend scoring, a set of responses from Time "A" are rescored by raters at Time "B." The purpose of this study is to examine the ability of…

Reliability is the consistency of a set of scores that are designed to measure the same thing. Reliability is a statistical property of scores that must be demonstrated rather than assumed.

Background: Primary school is key to developing writing skills. However, students may face challenges in identifying and revising articles due to weak language skills, organisational thinking, comprehension, and analytical skills. Therefore, improving the writing skills of primary school students with writing difficulties has become important.…

This study examines the impact of the College, Career, and Community Writers Program (C3WP) on upper-elementary students' first draft writing quality, addressing the challenges teachers face in providing timely and effective feedback on extensive student writing, particularly in spelling, grammar, mechanics, and cohesion. The hypothesis posits…

Fraction arithmetic facility is fundamental to learning more advanced math topics. However, attaining the ability to add and subtract fractions is hard for many students. The present longitudinal study examined students' growth on simple addition and subtraction word problems between fourth and sixth grades (N = 536). Latent class growth analyses…

Little is known about mismatches between the language of mathematics testing instruments and the rich linguistic repertoires that African American children develop at home and in the community. The current study aims to provide a proof of concept and novel explanatory item response design that uses error analysis to investigate the relationship…
