Background and purpose of the study: STEM learning often involves a multitude of complex and abstract concepts and ideas that can be challenging for students to comprehend. Research suggests that the oral and visual representations in video lectures can maximize students' cognitive infrastructure, helping them to organize knowledge more…

In the ever-changing digital era, the surge of online informal language learning platforms has revolutionized the way we learn new languages. This dissertation delves into the critical role of interactional feedback (IF) in synchronous computer-mediated communication (SCMC), a cornerstone for optimizing these digital learning spaces. Anchored in…

This practice brief provides educators with current research findings and evidence-based, high quality, instructional mathematics' practices from the Institute of Education Sciences' Practice Guide for teaching English learners (ELs) academic content, and highlights instructional practices used to teach ELs according to the National Academies of…

We conducted a multisite replication of Yang and Lyster's (2010) study investigating the effects of recasts and prompts on learning English regular and irregular past tense. Our study was conducted with intact high school and vocational school classes in Italy and Bosnia. Our participants were young adolescents (14-15 and 16-17 years old), a…

This study aimed to explore the relative effect of training English as a Foreign Language (EFL) learners in debates on their oral and written performance. It also investigated the effect of training on students' ideal second language (L2) self and communication apprehension. An intact class of English majors at a Saudi college (N=32) received…

Background: Research in the field of writing pedagogy within higher education has extensively examined the significant roles that feedback plays in the development of students' writing skills. However, comparative studies that investigate the efficacy of teacher-provided written and oral feedback, both with and without the aid of technology,…

Judgment tasks (JTs, often called acceptability or grammaticality judgment tasks) are found extensively throughout the history of second language (L2) research. Data from such instruments have been used to investigate a range of hypotheses and phenomena, from generativist theories to instructional effectiveness. Though popular and convenient, JTs…

The purpose of this meta-analytic review is to investigate the relation between statistical learning (SL) and language-related outcomes, and between SL and reading-related outcomes. A comprehensive search of peer-reviewed published research resulted in 42 articles with 53 independent samples and 201 reported effect sizes (Pearson's r). Results of…

Previous research has shown that explaining is an effective activity to enhance learning. In prior studies, students were instructed to explain the contents after completing an entire learning phase. Explaining at the end of a learning phase, however, may be less apt to support comprehension monitoring and subsequent regulation activities. In 2…

The role of recasts, a corrective feedback technique, has received much attention from instructed SLA researchers. While a variety of factors have been identified as influencing their effectiveness in facilitating uptake and L2 development (e.g., learners' age and level of proficiency), the role of mode of interaction has been the object of…

Despite empirical evidence from research showing that the use of text-picture combination is beneficial for second language (L2) learning, little is known about the effectiveness of reading comic books for incidental vocabulary acquisition. This study investigated the effects of engaging with comic books on incidental learning of L2 Italian…

Meta-syntheses have reported positive impacts of feedback for student achievement at different stages of education and have been influential in establishing feedback as an effective strategy to support student learning. However, these syntheses combine studies of a variety of different feedback approaches, combine studies where feedback is one of…

The benefit of Content and Language Integrated Learning (CLIL) for second language (L2) development has been addressed by second language acquisition theory and investigated by empirical studies. However, previous studies have not demonstrated the effectiveness of CLIL precisely as most of their study participants took CLIL and non-CLIL courses…

This experimental study examines the role of oral and written repetition strategies in consolidating new vocabulary in the classroom context. The participants in this study were divided into three treatment groups: oral, written and oral+written. A pretest and three delayed post-tests given at one day, one week and six weeks intervals were…

This study fills the existing gap in the research, which indicates that few researchers have examined multilingual writers' preference between audio and written feedback, and the impact of feedback format on their revision process. However, this dissertation has five interrelated purposes: 1. To understand the expectations of multilingual writers…
