Abstract
This study reports an investigation on the effects of directed vocabulary and whole class
instruction on improving students’ vocabulary acquisition and reading comprehension.
Fifty-eight seventh grade students participated in the study, and a pre-test/post-test
experimental design was employed. The results did not indicate any statistically
significant differences between the control and experimental group in reading
comprehension or vocabulary acquisition. However, considerable differences were found
in favor of the experimental group in reading comprehension.
