Description¶

The review organizes the factors enhancing incidental L2 vocabulary acquisition into three aspects: the word itself, the reading text, and the learners. Word factors cover "the predictability of word meanings, the certain word types such as high-frequency words, the certain word class such as no uns, a certain number of exposures of the word and the glossing of the word". Text factors are context quality and richness, topic familiarity and rhetorical organization; learner factors are proficiency, motivation, involvement and L1 lexicalization, with synonym generation disadvantageous.

Design Implications¶

Context¶

Requirements¶

• Applies to incidental vocabulary acquisition through reading in L2 English contexts as reviewed

Constraints¶

• Synonym generation is identified as disadvantageous to vocabulary acquisition

Target Learners¶

• L2 English learners across proficiency levels

Target Learning Objectives¶

• Incidental acquisition of L2 vocabulary meaning, form, and form-meaning connections through reading

Claims¶

• Exposure Frequency Predicts Incidental Gains [+M]
• Marginal Glosses Most Beneficial Task [+M]
• Proficiency Motivation Involvement Gains [+M]
• Incidental vocabulary gains show retention problems, with losses over time moderated by feedback timing and topic interest [+W]
• Mastery of incidental vocabulary learning strategies positively predicts L2 incidental vocabulary acquisition through reading [+W]
• L2 proficiency positively predicts L2 incidental vocabulary acquisition through reading [+W]
• L2 proficiency, anxiety, and mastery of strategies jointly explain 18% of variance in incidental vocabulary acquisition [+W]
• Motivation did not significantly predict L2 incidental vocabulary acquisition through reading [~W]
• Incidental vocabulary learning anxiety positively predicts L2 incidental vocabulary acquisition through reading [+W]
• Earlier meta-analyses, as reported second-hand, find that glosses improve L2 vocabulary learning and that text-and-picture glosses outperform single-mode glosses [+W]

Related Theories¶

Examples¶

• Combine implicit and explicit word instruction, ensure repeated exposures, and use interesting topics and delayed-feedback review to support vocabulary learning
• Develop learners' personal sets of effective vocabulary strategies rather than teaching arbitrary strategy lists
