Table 1: The Number of Words and Lessons in Book Three

Three hundred and thirty three lexical items included in the English textbook, namely,
Birjandy, P. & Norouzi, M. & Mahmoody, G. (2004). English Book Three, which is routinely
assigned by the Ministry of Education for EFL teaching in Iranian public high schools in Grade
three were taught to the participants in the present study. The book typically includes sections of
reading comprehension, grammar, pronunciation practice, dialogues, and a list of new words (with
no explanation of meaning or synonyms) in the ending part of each lesson. These wordlists (See
Appendix 1) were used for vocabulary instruction and subsequent vocabulary testing in the study.
To save space, the number of the new words in each lesson is presented in Table 1
