• Morphological instruction and reading development in young L2 readers: A scoping review of causal relationships (2021) · doi

  Findings suggested that (a) morphological instruction led to consistent and positive gains in L2 children’s morphological awareness and vocabulary knowledge, and the effect sizes (Cohen’s ds) ranged from small to large; and (b) the relationship between morphological instruction and other outcomes such as phonological awareness, word reading accuracy, word reading fluency, spelling, and reading comprehension was inconclusive.

  As research efforts have been devoted largely to exploring effective vocabulary teaching strategies and techniques, it remains unclear what teachers know and believe regarding L2 vocabulary acquisition beyond the commonplace conception that teaching and learning are interrelated.

• Using novel word context measures to predict human ratings of lexical proficiency (2017)

  Introduction While most researchers agree that lexical proficiency is an important component of second language (L2) language competence and academic achievement (Alderson, 2005; Daller, Van Hout, & Treffers-Daller, 2003; Laufer, 1992), the construct of lexical proficiency itself is still poorly understood and the field of L2 research lacks a unified theory of vocabulary acquisition (David, 2008; Schmitt, 2010).
