This study investigated students' successes, strategies, and common errors in their answers to questions that involved the electron-pushing (curved arrow) formalism (EPF), part of organic chemistry's language. We analyzed students' answers to two question types on midterms and final exams: (1) draw the electron-pushing arrows of a reaction step,…

Wollack, Cohen, and Eckerly (2015) suggested the "erasure detection index" (EDI) to detect fraudulent erasures for individual examinees. Wollack and Eckerly (2017) extended the EDI to detect fraudulent erasures at the group level. The EDI at the group level was found to be slightly conservative. This paper suggests two modifications of…

In order to help students to spell accurately, both students and teachers need to be aware of the causes of their spelling errors. Several methods have been developed for analysing spelling errors. Some researchers, such as Bruck and Waters (1988) and Bebout (1985), have categorised the phonetic errors that were made. Others, such as Brooks et al…

During the pandemic of Coronavirus disease 2019 (COVID-19), English as a foreign language (EFL) students have to study and submit their assignments and quizzes through online systems using electronic files instead of hardcopies. This has created an opportunity for teachers to use computer tools to conduct preliminary assessment of the students'…

With the change in socio-political and educational contexts in global academia, the trend of writing academic papers has arisen among Nepali students and educators in higher education. However, many of them are still unfamiliar with the basic standard to be incorporated in an academic paper. In this context, this study examined the post-graduate…

We study the automatic identification of educational items worthy of content authors' attention. Based on the results of such analysis, content authors can revise and improve the content of learning environments. We provide an overview of item properties relevant to this task, including difficulty and complexity measures, item discrimination, and…

There is growing evidence that dyslexia may involve difficulty with implicit learning, which may hinder learners with dyslexia to acquire spelling skills in a foreign language through implicit instruction. Paradoxically, this is exactly how Dutch students with dyslexia learn English spelling at school. This research aims to determine if…

This study investigates the effectiveness of using Google Translate as a translingual CALL tool in English as a Foreign Language (EFL) writing, keyed to the perceptions of both more highly proficient Chinese English major university students and less-proficient non-English majors. After watching a 5-minute passage from a movie, each cohort of…

Purpose: This retrospective study was intended to replicate findings from Sacks et al. (2013) regarding the efficacy of using the SATPAC (Systematic Articulation Training Program Accessing Computers) approach for remediating speech sound errors in a Tier 3 response to intervention (RTI) context. Method: Nine children aged 7;7 (years;months) to…

This study aims to: (i) describe the different meanings and contexts in which Arabic "dar" and "bayt" and English "house" and "home" expressions are used; (ii) compare "dar," "bayt," "house" and "home" expressions and give examples of expressions that are identical in…

The purposes of this study are threefold: It investigates effects of a formative assessment script (FAS) that was designed to support vocational students in generating feedback to (1) a peer's and (2) their own performance. Effects of the FAS are investigated with respect to quantitative and qualitative characteristics of the peer and internal…

Purpose: The purpose of this study was to determine how 2 methods known to improve naming impairment in aphasia (i.e., retrieval practice and errorless learning) affect lexical access. We hypothesized that instances of naming during retrieval practice use and strengthen item-specific connections in each of 2 stages of lexical access: Stage 1,…

Assessment of clinical competence is complex and inference based. Trustworthy and defensible assessment processes must have favourable evidence of validity, particularly where decisions are considered high stakes. We aimed to organize, collect and interpret validity evidence for a high stakes simulation based assessment strategy for certifying…

This paper illustrates the use of learner corpus data (extracted from Cambridge Learner Corpus--CLC) to carry out an error analysis to investigate authentic learner errors and their respective frequencies in terms of types and tokens as well as contexts in which they regularly occur across four distinct proficiency levels, B1-B2; C1-C2, as defined…

To diagnose classroom situations is crucial for teachers' everyday practice. The approach of worked examples with errors seems promising to support the diagnosis of classroom situations in student teachers (Stark et al. in "Learn Instr" 21(1):22-33, 2011). To enhance that approach, error-explanation prompts and an adaptable feedback…
