Description

The article supports using supplementary textbooks such as Gaj and Khate Sefid alongside the national academic textbook in EFL reading instruction. In the study, experimental classes used selected reading texts from these supplementary books in addition to the normal textbook, while the control class used only the national book. The authors conclude that "using supplementary text books as an instructional tool had a positive impact on reading comprehension of English learners in experimental groups."
