This study aimed at investigating the effectiveness of using keyword-based instruction on developing eighth graders' English vocabulary and its retention. To achieve the study aims, the researcher adopted the experimental approach in which he purposively selected a representative sample of (78) eighth graders from Al Shaheed Mohammed Addorra Basic School for Boys. The participants were distributed into two equivalent experimental and control groups: a control group consisting of (38) students and an experimental group consisting of another (40) students. The researcher designed (8) lessons using keyword strategy which were used in teaching the experimental group, while the conventional method was used in teaching the control one during the second term of the school year (2015-2016). The researcher prepared an achievement test (pre, post &delayed) to collect data. The data of the study were analyzed using T-test Independent sample and T-test paired sample. Effect size technique was used to measure the effect size of keyword strategy on the experimental group. The findings of the study revealed that there were statistically significant differences between the mean scores attained by the experimental group and those attained by the control group in the post application of the vocabulary achievement test in favor of the experimental group due to the use of the keyword strategy in favor of the post application. Thus, the findings of the study revealed that the keyword strategy was effective in developing students’ English vocabulary and its retention. In the light of those findings, the researcher recommends the necessity of using the keyword strategy in teaching English vocabulary to eight graders. Moreover, the researcher suggested that further research should be conducted to explore the effect of the use of the keyword strategy on different English language skills and other school subjects and grades.
