This article offers a critical review of research on the use of glossing and its contribution to second language (L2) vocabulary acquisition. Discussion topics include the complexity of estimating the effectiveness of glossing relative to reading non-glossed texts, the quest for optimal implementations of glossing, issues of ecological validity, and ambiguity around the nature of vocabulary learning from glosses. The general conclusion is that, despite the substantial number of research studies on this subject, many questions remain to which only tentative and provisional answers are currently available. This is partly owing to the wide diversity in research designs across studies and the lack of transparency of many research reports. Suggestions are made for further research on glossing with a view to enabling future systematic reviews to produce more nuanced answers and more informed recommendations for the design of L2 reading materials.

光泽和词汇学习

本文对有关使用修饰的研究及其对第二语言 (L2) 词汇习得的贡献进行了批判性审查。讨论的主题包括估计注释相对于阅读非注释文本的有效性的复杂性、对注释的最佳实施的追求、生态有效性问题以及围绕从注释中学习词汇的性质的模糊性。总的结论是，尽管有大量关于这一主题的研究，但仍有许多问题，目前只有初步和临时的答案。这部分是由于研究设计的广泛多样性以及许多研究报告缺乏透明度。
