The Effects of Mnemonic Vocabulary Instruction on Content Vocabulary Learning of Students
The present article is an investigation about the effects of mnemonic vocabulary teaching to improve content vocabulary learning in EFL classrooms. A major issue with the most of the past studies was that they paid little or no attention to the effects of using mnemonic strategies to improve content vocabulary learning. The purpose of this paper is to investigate how key word mnemonic vocabulary teaching can improve the comprehension and learning of the content vocabulary for the students. To this end, 256 third year senior high school students from 6 senior high schools in Zanjan (Iran) were selected through a multistage cluster random sampling method and based on the Cambridge placement test (2010), 230 students proved to be upper intermediate. A quasi-experimental design was used to determine the effects of a mnemonic vocabulary intervention on content vocabulary learning. In this article there were one control group (A, n=115), and one experimental group (C, n=115) all of which were male and there were selected randomly. This study was done in May 2017, and over four weeks, in two thirty-minute sessions per week, group C received key word mnemonic instruction. In order to test the effects of mnemonic vocabulary teaching on content vocabulary learning, the covariance analysis was employed and the results demonstrated that by eliminating the covariance factor of the pre-test, mnemonic vocabulary instruction improved content vocabulary learning for students. The use of keyword mnemonics as a means to differentiate instruction is an educational result that can assist teachers.
