We discuss an original study and two replications conducted over 18 years examining the impact of Teacher Study Group (TSG) in Vocabulary, a professional development (PD) approach for improving pedagogy and student learning. Study 1 focused on the design and development of the PD and included a small-scale randomized controlled trial to assess the…

Vocabulary proficiency diagnosis plays an important role in the field of language learning, which aims to identify the level of vocabulary knowledge of a learner through his or her learning process periodically, and can be used to provide personalized materials and feedback in language-learning applications. Traditional approaches are widely…

Research has shown that novel words can be learned through the mechanism of statistical or cross-situational word learning (CSWL). So far, CSWL studies using adult populations have focused on the presentation of spoken words. However, words can also be learned through their written form. This study compared auditory and orthographic presentations…

This study explored the effects of listening-based lexical focus-on-form (lexical FonF) on the acquisition and retention of morphologically complex words. One hundred eighty-two adult English learners with two levels of English proficiency (higher and lower proficiency) from a public university in mainland China were assigned to three different…

Research has shown that learning a known-and-unknown word combination leads to greater learning than learning an unknown word alone (Kasahara, 2010, 2011). These studies found that attaching a known adjective to an unknown noun can help learners remember the unknown noun. Kasahara (2015) found that a known verb can serve as an effective cue to…

Reading comprehension difficulties have been associated with poor vocabulary knowledge of children with autism spectrum disorder (ASD). Research has shown that Dialogic Reading (DR) interventions may remediate these deficits. The purpose of this study was to compare the effectiveness of two DR intervention protocols on the vocabulary knowledge of…

This study examines the impact of WebQuests on the vocabulary and reading skills of ESL students in Saudi Arabia's technical colleges. The primary objectives of the study are to determine whether WebQuests can improve the vocabulary and reading skills of ESL learners and to explore their perceptions regarding the use and impact of WebQuests on…

We examined the impact of images on novel word learning and consolidation, in a conceptual replication of Liu and Van Hell (2020). After participants had learned one set of novel words with definitions and images on Day 1 (remote words) and a different set on Day 2 (recent words), they judged the semantic relatedness of word pairs on Days 2 and 8…

Scholars have suggested English classrooms with sufficient context and fun activities to increase English performance and promote learning motivation. With the rapid growth of technology-enhanced learning, virtual reality (VR) has become increasingly popular in English learning. Using VR without a well-designed learning environment, however, may…

This research investigated the effect of three definitional, sentential, and textual vocabulary learning strategies on Iranian intermediate EFL learners' vocabulary learning and retention. Based on Oxford Solutions Placement Test, of 94 total population, 66 Iranian EFL learners were selected as homogeneous participants at the intermediate level…

Several studies have explored the use of iconic gestures to improve the learning of foreign vocabulary. In this quest, words for abstract concepts have been largely neglected, under the assumption that abstract concepts have poor or non-existent sensory-motor representations. Yet, the Conceptual Metaphor Theory suggests that they are grounded on…

Learning part names, such as hands of a clock, can be a challenge for children because of the whole object assumption; that is, a child will assume that a given label refers to the whole object (e.g., a clock) rather than the object part (e.g., hands of a clock). We examined the effect of gaze shifting and deliberate pointing on learning part…

Vocabulary learning constitutes an essential component of language learning and teaching. The type of input students receive is one of the factors that affect the pace and range of this learning. In the incidental vocabulary learning process, learners have been shown to benefit from exposure to a variety of input types to varying degrees. In this…

This study tried to design a WhatsApp bot to be implemented in English language vocabulary learning context in Oman. 150 Omani English as a Foreign Language (EFL) students from three different proficiency levels were selected based on random sampling. To measure the effectiveness of the treatment, pretests, posttests, and delayed posttests were…

There has been little research investigating how mode of input affects incidental vocabulary learning, and no study examining how it affects the learning of multiword items. The aim of this study was to investigate incidental learning of L2 collocations in three different modes: reading, listening, and reading while listening. One hundred…
