All communication systems rely on sets of rules that must generally be followed for successful communication to be possible; in the case of human language, these rules are given by the grammar. However, despite these rules, there is considerable variation that has been noted across the grammar. In this dissertation, I explore one understudied…

Previous research has documented positive effects of pre-task planning on task-based performance, commonly analyzed in terms of complexity, accuracy, and fluency, in an L2. However, the sources of planning have rarely been examined in the research of task-based language teaching. The present study explored EFL learners' oral performance across the…

This study investigated the optimum task sequence for second language (L2) novice learners of English. One set of task sequences was manipulated using a deductive and theoretical SSARC (simplify-stabilize-automatize-restructure-complexify) model, and two sets of task sequences were manipulated based on a teacher's inductive classroom observations.…

We conducted a meta-analysis to investigate reading-writing relations. Beyond the overall relation, we systematically investigated moderation of the relation as a function of linguistic grain size (word reading and spelling versus reading comprehension and written composition), measurement of reading comprehension (e.g., multiple choice,…

Aim/Purpose: This study examines the effects of the mobile-assisted task-based language teaching (M-TBLT) approach on EFL learners' oral production. It evaluates three key second language acquisition measures: complexity (syntactic and lexical), accuracy (error-free clauses and correct verb forms), and fluency (unpruned and pruned speech rates).…

Conversely to plenty of studies describing how L1 transfer affects L2 systems, where the two grammars, L1/L2, often only come to interact later in life, less is known of dominant language transfer in heritage language grammars. Unlike in L2 speakers, the dominant language of the heritage speaker potentially affects its weaker language already from…

Adult first language (L1) English speakers who are advanced second language (L2) learners of Spanish demonstrate near-ceiling levels of accuracy for some features of Spanish, such as [Person] and [Number] for verbs (McCarthy, 2012; Rodgers, 2011). While for other features, such as [Aspect] for copulas (i.e. ser and estar), and [Person] and…

Although a considerable number of studies have shown D(eterminer) elements, i.e. determiners and pronominal clitics, to be particularly vulnerable to impairment in monolingual children with Developmental Language Disorder (DLD), little is known about the use of appropriate or/and grammatically correct referring expressions in the children's…

The present study investigated the speaking module of TOEFL iBT with an emphasis on the dichotomy of independent and integrated tasks. The potential differences between the two speaking conditions were intended to be explored based on the oral performance elicited from a group of Iranian test takers. To collect the required data, a simulated…

The present study examined the effects of using automatic speech recognition (ASR) technology on oral complexity in a flipped English as a Foreign Language (EFL) course. A total of 160 undergraduates were enrolled in a 14-week quasi-experiment. The experimental group (EG) and the control group (CG) were taught with a flipped approach, but the EG…

Listening comprehension is a real-time process, yet very little is known about the variables affecting real-time second language (L2) listening. The present study aimed at investigating the effects of syntactic complexity and word frequency on L2 listening. Furthermore, the role of the listener's working memory capacity in listening comprehension…

This study investigates the impact on L2 oral performance of participatory structure of strategic planning (individual vs. collaborative pair planning) and task complexity (simple vs. complex tasks) defined according to the number of elements involved. It also explores individual and collaborative planners' planning behaviours prior to simple vs.…

In Turkish, null and overt arguments do not show the same distributional properties at discourse level. There are discourse-pragmatic factors affecting this distribution (Kerslake, 1987; Ruhi, 1996; Turan, 1995; Çeltek & Oktar, 2014; Çeltek Kaili, 2017). Previous studies suggest that the acquisition of argument realization system in second…

Prior research on pre-task planning examines its effects on the quality of second language (L2) learners' planned output. Planning mitigates the cognitive overload placed upon L2 learners' oral performance, thus improving language production. Despite the pedagogical benefits, studies on pre-task planning on L2 learners' oral output are conducted…
