Developing Strategies to Improve Textbook Design Using Synergy of Native and Learner Corpora

Area of Science:

• Linguistics
• Applied Linguistics
• Corpus Linguistics

Background:

• English as a Foreign Language (EFL) textbooks often lack authentic language use.
• Modal verbs (MVs) are crucial for expressing nuances in English but pose challenges for learners.
• Corpus linguistics offers insights into real-world language patterns.

Purpose of the Study:

• To compare modal verb usage in EFL textbooks with native speaker corpora.
• To analyze the developmental patterns of modal verb acquisition in student writing.
• To propose improvements for EFL textbook design based on corpus data.

Main Methods:

• Comparative corpus analysis of EFL textbooks and the British National Corpus (BNC).
• Stratified analysis of modal verb usage in student essays (Grades 7-9).
• Examination of L2 form salience and complexity in learner production.

Main Results:

• Significant discrepancies exist between modal verb use in EFL textbooks and the BNC.
• EFL textbooks exert a considerable influence on learners' modal verb production.
• Learner essays demonstrate distinct developmental patterns in modal verb acquisition.

Conclusions:

• EFL textbook design requires enhancement for greater authenticity.
• Integrating native and learner corpora can inform targeted instruction and curriculum development.
• Learner-centric approaches and authentic language examples are vital for effective EFL learning.
