This dissertation developed a new learner corpus of Japanese and introduced an error and linguistic annotation scheme specifically designed for Japanese particles. The corpus contains texts written by learners who are in the first year to fourth year university level Japanese courses. The texts in the corpus were tagged with part-of-speech and…

This study is intended to help English foreign language learners avoid a type of syntactic ambiguity in sentences resulting from prepositional phrases (PPs). The students are guided to make use of the features of both adverbials and adjectivals in resolving this type of ambiguity. The movability of adverbials and the use of relative clauses…

This study investigated the effects of explicit and implicit discourse marker (DM) instruction on English as a foreign language (EFL) learners' speech. Two different teaching methods were used over seven weeks of online English classes at a university in Japan. Participants were split into two groups, and in the first week, a pre-test comprising…

Prior research showed that interleaved practice (studying multiple skills at once) is more effective than blocked practice (studying only one skill at a time). This study aims to replicate the benefits of interleaved practice on the proceduralization of second language (L2) syntax and further examines the role of working memory (WM) in different…

Adopting Hyland's (2002) framework of reporting words (RVs), the paper investigates the use of RVs in Master's theses written in English by students of two disciplines, Economics and Management and Natural Resources. The data were drawn from two sub-corpora, each consisting of 82 Literature Reviews, where other authors' research is summarised and…

Purpose: The present article reports on the implementation and results of a randomized intervention trial targeting the literate language skills of prekindergarten children without identified language disorders but with low oral language skills. Method: Children (N = 82; 45 boys and 37 girls) were screened-in and randomized to a business-as-usual…

The study compared the effects of two types of form-focused written feedback--direct corrective feedback (DCF) and metalinguistic explanation (ME) given to the whole class--on Japanese university students' accuracy of use of two grammatical structures: indefinite article and the hypothetical conditional. Both types of feedback were given with…

Past research has emphasized the universality of grammar acquisition over key differences, resulting in the development of a number of one-size-fits-all approaches to grammar instruction. Because such approaches fail to consider disparities of grammatical features, they are often ineffective. Just as a doctor needs to diagnose an illness and…
