Abstract

Typical print formatting provides no information regarding the linguistic features of a text, although texts vary considerably with respect to grammatical complexity and readability. Complex texts may be particularly challenging for individuals with weak language knowledge, such as English language learners. This paper investigates the usefulness of a text format referred to as Linguistically-Driven Text Formatting (LDTF), which provides visual cues to grammatical structure for in-the-moment language support during reading. We assessed reading comprehension in adult English Language Learners after a two-session exposure to the new format (also called Cascade Format). Participants’ primary languages were Mandarin and Korean, which have substantially different syntactic structures from English. Ninety participants (30 L1 English, 30 L1 Mandarin, 30 L1 Korean) were randomly assigned to either the traditional or the LDTF format and read six English passages across two sessions within the same week. Comprehension was assessed via questions that probe sentence comprehension and global text properties. Participants also completed a TOEFL assessment, presented in either LDTF or traditional format. Bayesian analyses showed that the Cascade Format improved sentence comprehension relative to control participants for all language groups and experience levels. Effects on the TOEFL assessment, which taps inferencing and meta-linguistic skills, were not observed. Syntactic knowledge plays a fundamental role in reading comprehension, and LDTF appears to support comprehension by providing visual cues to this knowledge that can be used at the very moment of meaning construction.

Notes

  1. Whereas syntactic knowledge can be defined as the ability to recognize and interpret syntactic grammatical structures during reading, syntactic awareness represents a more metalinguistic skill that allows readers to reflect upon and manipulate these structures (Tunmer et al. (1988)). Although both are predictors of comprehension, recent work by Brimo and colleagues (2017) show that syntactic awareness is only a significant predictor when mediated by syntactic knowledge, thus syntactic knowledge is likely the better predictor for more immediate comprehension abilities.

  2. The lowest effect size of 0.73 was found by Spada and Tomita (2010) for explicit instruction of simple linguistic features.
