An analysis of lexicogrammatical development in English textbooks in Turkey: A usage-based construction grammar approach

Summary/Abstract: This article measures the syntactic development indices in grade 5-12 English textbooks in Turkey. Through a usage-based construction grammar approach, it argues. that the textbooks show an inconsistent development in verb-argument constructions (VAC) and other usagebased indices. The study employs an automatic software tool that detects variations in these indices and runs a statistical analysis on a corpus compiled by the author. Statistically significant results demonstrate that textbooks lack lexicogrammatical variation. As such, learners who use these textbooks are likely to experience a limited array of VACs that are limited in lemmaconstruction combinations. Findings also indicate that learners may not be exposed to the conventional usage patterns and frequencies of VACs when compared against a reference corpus. These findings may have an influence on the learners’ generalization process, their low proficiency level in English, and poor idiomatic uses of the language
