Using Keyword Mnemonics to Improve Students Retention of English Vocabulary and Concepts among Grade 9 Students

Enhancing students' retention of vocabulary and concepts is crucial for improving their comprehension and performance in English language learning. The study aims to determine the level of retention before and after the implementation of keyword mnemonics, assess any significant differences, and evaluate the effectiveness of this strategy. The research employed a single group pretest-posttest design, with 28 purposively selected Grade 9 students as the respondents. Data were gathered using a researcher-made vocabulary test and lesson plans that integrated keyword mnemonics. The statistical tools used for data analysis were frequency and percentage, mean and standard deviation, and paired t-test. The findings revealed that students showed low retention before the intervention and significant improvement afterward, with all students achieving an “Outstanding†performance level post-intervention. The study revealed a highly significant difference in the students' retention of English vocabulary and concepts before and after the implementation of the keyword mnemonic strategy. Keyword mnemonics significantly enhances students' retention of English vocabulary and concepts. English teachers should incorporate keyword mnemonic strategies into daily vocabulary instruction to improve student retention and comprehension.
