For the sake of achieving the research purpose, an experimental method with an experimental design has been conducted where two groups were randomly assigned as experimental and control groups. The target sample comprised thirty-four students studying third year at Annab Naamon Middle School in Souk Naamane Oum-El-Bouaghi- for the academic year 2015- 2016. Additionally , participants of bth experimental and control groups were pre-tested using vocabulary tasks. After administering the pre-test, the treatment has been conducted for both groups for five sessions. The experimental group was taught through repetition and the control group was taught vocabulary in the ordinary method. Then, both groups were post-tested through another vocabulary test. After analyzing the obtained results, the alternative hypothesis was proved. That is to say, repetition has a positive effect on developing students ability to acquire vocabulary incidentally.enTeaching : english : EFL : vocabularyOther
