As an important practice for researchers, citing sources is a challenging task for undergraduate students as they deal with the types of citation forms, the variety of reporting verbs and their tenses, and the writer stances through reporting verbs. Therefore, the current research is aimed at investigating the surface forms, reporting verb tenses,…

The purpose of this study is to analyze the grammatical complexity features of international teaching assistants' (ITAs) mock-teaching presentations and to compare the distributions of these features to those found in the Oral English Proficiency Test (a local ITA assessment), university classroom teaching, conversation, and academic writing. The…

Power distance (PD), a cultural value denoting acceptance of asymmetrical power relationships, influences the force of rhetoric used by a writer to address their reader. However, AI technologies such as ChatGPT lack an explicit awareness of PD, which could affect the quality of AI-generated persuasive texts used for language learning. To…

Source-based writing is a complex and frequently occurring task type in postsecondary education. While a large body of research now exists investigating source-based student writing, few studies have used corpus-based methods to investigate L1 student performance on source-based writing tasks and to connect this performance to the holistic quality…

This study investigates the relative efficacy of using linguistic micro-features, the aggregation of such features, and a combination of micro-features and aggregated features in developing automatic essay scoring (AES) models. Although the use of aggregated features is widespread in AES systems (e.g., e-rater; Intellimetric), very little…

Over the past 45 years, the construct of syntactic sophistication has been assessed in L2 writing using what Bulté and Housen (2012) refer to as absolute complexity (Lu, 2011; Ortega, 2003; Wolfe-Quintero, Inagaki, & Kim, 1998). However, it has been argued that making inferences about learners based on absolute complexity indices (e.g., mean…

The authors present a model of lexical proficiency based on lexical indices related to vocabulary size, depth of lexical knowledge, and accessibility to core lexical items. The lexical indices used in this study come from the computational tool Coh-Metrix and include word length scores, lexical diversity values, word frequency counts, hypernymy…
