This study examines whether ten weeks of direct instruction of affixes with online systems can improve learners' knowledge of affixes by using Affix Master 10 (AM10), a collection of online self-study materials developed by the current researchers. The aim of AM10 is to let students comprehensively learn 30 prefixes and 31 suffixes. The two…

It is generally agreed that first language (L1) morphological awareness, the ability to reflect upon, analyze and manipulate morphemes and morphological structure of words, can transfer and facilitate second language (L2) reading subskill acquisition. However, the facilitative role of L1 morphological awareness is unclear in the literature…

The selection of an appropriate word counting unit (WCU) for the purpose of second/foreign language vocabulary acquisition (SLVA) in the last decade has become a very important and relevant topic in academic circles. However, few studies address on-the-ground teaching practices and perspectives. This mixed-approach study, conducted through an…

This article describes the development of a tense and aspect identifier, an online tool designed to help learners of English by harnessing a natural language processing pipeline to automatically classify verb groups into one of 12 grammatical tenses. Currently, there is no website or application that can automatically identify tense in context,…

The Interface Hypothesis (Sorace, 2000) developed in line with the Minimalist theory of grammar (Chomsky, 1995 et seq.) supports the view of L2 acquisition that syntactic properties are acquired early while the acquisition of interface properties is delayed. One of the interface properties is inflectional morphology on English verbs, which…

This study focused on the grammatical accuracy of Japanese students who were learning English. The database for the errors came from the Japanese University Student Corpus (JUSC) comprising 61 transcripts containing 51,061 words. An inventory, containing 400 errors in context, was taken from this corpus. The first research question related to the…

Knowledge of English affixes plays a significant role in increasing knowledge of words. However, few attempts have been made to create a valid and reliable measure of affix knowledge. The Word Part Levels Test (WPLT) was developed to measure three aspects of affix knowledge: form (recognition of written affix forms), meaning (knowledge of affix…

The present study investigated the interface between explicit instruction and computer-assisted language learning (CALL) in an effort to reduce plural marking errors among Japanese EFL learners. The instruction involved raising contrastive awareness of cross-linguistic and conceptual features, and was delivered via an online medium. A total of 180…

In our globalised world, the desire for the acquisition of English has led to increased research into the appropriate pedagogical approaches for learning and teaching the language. This manuscript focuses on the use of learners' mother tongue in the learning and teaching of English in an effort to identify ways in which cross-linguistic…

Languaging has been identified as a contributor to language learning. Yet, compared to oral languaging, such as collaborative dialogs in contextualized settings, little seems to be known about written languaging. In order to fill this gap, this study investigates languaging in the form of "metanotes," that is, metatalk in a written…

Recently, the use of children's picture books to teach English has been increasing in Japan. An advantage of these books is the high proportion of basic vocabulary they include. Can picture books also be useful for teaching Japanese students Italian and increasing their motivation? The present study analyses the effectiveness of employing a…

This article examines the issue of cognates in frequency-based vocabulary size testing. Data from a pilot study for a cognate-controlled English vocabulary size test was used to assess whether a group of Japanese university English learners (n = 60) were more successful at responding to cognate items than noncognate ones in three 1000 word…

The study investigates whether advanced second language (L2) learners can extend beyond the grammatical properties of the first language (L1) to successfully acquire tense and aspect. We examine the acquisition of the semantics of the imperfective marker "te-iru" in Japanese by native speakers of Mandarin Chinese, a language that…

The present study investigated the existence of a Japanese mental syllabary and units stored therein for speech production. Experiment 1 compared naming latencies between high and low initial mora frequencies using CVCVCV nonwords, indicating that nonwords with a high initial mora frequency were named faster than those with a low frequency initial…

Detailed research concerning the issue fluency, specifically relating to pauses, mean length runs, and fluency rates in Japanese EFL learners, is limited. Furthermore, the issue of tracking fluency gains has often been ignored, misunderstood or minimized in EFL educational research. The present study, which is based on six monologues conducted…
