Recommendations for Classroom-based TESOL Research: L2 Instructed Vocabulary Acquisition as an Exemplar
Second language acquisition research (SLA) is in the midst of a methodological reform, particularly within its quantitative domain. This reform has produced a body of work, comprising systematic reviews and meta-analyses, and has resulted in recommendations relating to the practices of SLA researchers. In the spirit of the methodological reform, during this presentation we will discuss research pertaining to an important subfield of SLA, second language instructed vocabulary acquisition (L2 IVA) research, which concerns how target lexical items are learned, specifically in the classroom context, and also the factors influencing the process. The practices of L2 IVA researchers were assessed via the analysis of almost 100 studies published in six journals since the beginning of the 21st century. The results indicated that L2 IVA research will benefit from a more robust approach to sample size planning, and a set of recommendations for future research will be laid out.
