This study extends past research on students' understanding of slope by analyzing college students' mistakes on routine tasks involving slope. We conduct quantitative and qualitative analysis of students' mistakes to extract information regarding slope conceptualizations described in prior research. Results delineate procedural proficiencies and…

The aim of the present study is to compare the writing products of English as a Foreign Language (EFL) university students using accuracy and grammatical complexity as measures. It also aims at examining the development of the morphological, syntactic, lexical, spelling, and punctuation errors committed by these learners when writing in English.…

There is a contemporary emphasis on researching the effects of phonological awareness on reading skills though morphological awareness correlates more highly with reading. The purpose of the study was to investigate the patterns of reading errors from a morphological perspective (level of morphological complexity) and lexical category. One hundred…

While there is a plethora of research on pronunciation problems of EFL learners with different L1 backgrounds, published empirical studies on syllabification errors of Iraqi Kurdish EFL learners are scarce. Therefore, to contribute to this line of research, the present study set out to investigate difficulties of this group of learners in the…

Previous research has shown that both dictation and speech-to-text (STT) software can increase the quality of writing for native English speakers. The purpose of this study was to investigate the effect of these modalities on the written composition and cognitive load of elementary school English language learners (ELLs). In a within-subjects…

The present study tests whether presenting video modeling examples from the learner's (first-person) perspective promotes learning of an assembly task, compared to presenting video examples from a third-person perspective. Across 2 experiments conducted in different labs, university students viewed a video showing how to assemble an 8-component…

Modeling multidimensional test data with a unidimensional model can result in serious statistical errors, such as bias in item parameter estimates. Many methods exist for assessing the dimensionality of a test. The current study focused on DIMTEST. Using simulated data, the effects of sample size splitting for use with the ATFIND procedure for…

Learning algebra is difficult for many students in part because of an emphasis on the memorization of abstract rules. Algebraic reasoners across expertise levels often rely on perceptual-motor strategies to make these rules meaningful and memorable. However, in many cases, rules are provided as patterns to be memorized verbally, with little overt…

Although it is widely acknowledged that collocations play an important part in second language learning, especially at intermediate-advanced levels, learners' difficulties with collocations have not been investigated in much detail so far. The present study examines ESL learners' use of verb-noun collocations, such as "take notes," "place an…
