Perceptual characteristics of mathematical equations may influence solvers' problem solving. For example, in a study of equations involving addition and multiplication, Landy and Goldstone (2010) showed that participants tended to perform narrowly spaced operations first, suggesting that spacing affects how symbols are grouped for problem solving.…

Language-impaired individuals with autism perform poorly on tests such as non-word repetition that are sensitive clinical markers of specific language impairment (SLI). This has fuelled the theory that language impairment in autism represents a co-morbid SLI. However, the underlying cause of these deficits may be different in each disorder. In a…

The aim of this study was to propose a didactical situation for the confrontation of the epistemological obstacle of linearity (routine proportionality) and consequently for the enhancement of meta-analogical awareness. Errors caused by students' spontaneous tendency to apply linear functions in various situations are strong, persistent and do not…

The study anchors on the Linguistic research tradition of Error Analysis (EA), focused on the grammatical errors, specifically on "verb tenses" manifested in the sentences of Japanese ESL learners. The entire respondent population was drawn from the pool of registered learners in 2017 at the Clark Institute of the Philippines Foundation,…

Although finding the limits of the difference quotients in the definitions of the derivative is troubling for many students, a difficulty that preceded this confusion was observed: students were not able to correctly set up the difference quotients as required in the definitions. The purpose of this study is to uncover student errors in setting up…

The study by Tamburelli, Jones, Gobet, and Pine (2012; henceforth TJGP) is a very welcome addition to the body of work concerning nonword repetition in typical development. TJGP go beyond previous work in considering three syllabic positions--onset, nucleus, and coda--with the aim of investigating how the positional role of phonemes within the…

Data analysis methods, both numerical and visual, are used to discover a variety of surprising patterns in the errors associated with successive approximations to the derivatives of sinusoidal and exponential functions based on the Newton difference-quotient. L'Hopital's rule and Taylor polynomial approximations are then used to explain why these…

Children with developmental dyslexia (DD) may differ from typical readers in aspects other than reading. The notion of a general deficit in the ability to acquire and retain procedural ("how to") knowledge as long-term procedural memory has been proposed. Here, we compared the ability of elementary school children, with and without…

The pressures inherent in trying to be perfect can undermine learning and exacerbate anxiety in certain students. In the current article, we review existing research and theory on the role of perfectionism in language learning anxiety and performance deficits. Our analysis highlights the complexities inherent in the perfectionism construct,…

The present research work deals with subtitling errors encountered by simulators and proof-readers. The resultant work is of significant contribution to problem decision makings in the field of quality assessment of audiovisual translation (AVT). The outcome of this paper is the result of accumulated working experience in this domain. The relevant…

Learning to ensure patient safety in complex health care environments is an internationally recognised concern. This article explores and compares Finnish (n = 22) and British (n = 32) pre-registration nursing students' important learning events about patient safety from their work placements in health care organisations. Written descriptions were…

The article introduces learners between two age groups: childhood and adulthood. The aim of the author is to analyse the writing skills of French primary school learners--mostly 14 years old--and to determine which descriptors could be used to assess them. The article begins with a presentation of the learners' characteristics and continues with a…

This study investigated middle school students' conceptual understanding of algebraic equations. 257 sixth- and seventh-grade students solved algebraic equations and generated story problems to correspond with given equations. Aspects of the equations' structures, including number of operations and position of the unknown, influenced students'…

The present study aimed to examine the relationship between letter processing and word processing skills in deaf and hearing readers. The participants were 105 students (51 of them hearing, 54 of them deaf) who were evenly and randomly recruited from two levels of education (primary = 3rd-4th graders; middle = 6th-7th graders). The students were…

Phylogenetic trees are widely used visual representations in the biological sciences and the most important visual representations in evolutionary biology. Therefore, phylogenetic trees have also become an important component of biology education. We sought to characterize reasoning used by introductory biology students in interpreting taxa…
