The challenge and the opportunity of lexical inferencing in language minority students

Lexical inferencing from text is a powerful tool for vocabulary and reading comprehension enhancement. Lexical inferencing relies on the pre-requisite skills of reading and existing vocabulary, and is also linked to non-verbal inferencing abilities and reading comprehension. In this study, we examined whether Fifth-grade Russian-speaking language minority (LM) students might exhibit reduced lexical inferencing abilities in comparison to their native Hebrew-speaking (NH) peers, due to their reduced proficiency in the societal language. Participants completed a measure of lexical inferencing during text reading, and measures of underlying skills, including vocabulary, word reading accuracy, reading comprehension and non-verbal inferencing. As a group, LM students demonstrated comparable lexical inferencing abilities to those of their NH peers despite significantly lower vocabulary knowledge in vocabulary. Two explanations are suggested; first, although LM students had reduced vocabulary, they were nonetheless above the vocabulary threshold required for text comprehension. Second, the regression analyses revealed that non-verbal inferencing explained unique variance only in the LM group, demonstrating that they recruited language-external resources to support lexical inferencing. The current results show that lexical inferencing can serve as a powerful tool for promoting reading comprehension and vocabulary, domains that are points of weakness for language minority students.
