The Mnemosyne computer software is a flash-card aid, which optimizes learners’ learning process. The current study was conducted to evaluate the extent to which Mnemosyne can assist college-level Iranian EFL learners to improve their vocabulary learning by utilizing spaced repetition. For this purpose, 60 intermediate-level EFL learners were chosen based on their performance on a proficiency test. Then, they were divided into two equal-sized experimental and control groups, each consisting of 30 participants. The participants of the experimental group were asked to use Mnemosyne on their own computers, their cell phones or other devices. They had opportunity to use numerous numbers of free flashcards on various subjects and users could build their own on different topics. The control group received instructions through conventional teaching methodology. The posttest was given to the participants of both groups in order to check the students’ vocabulary learning. The results of independent sample t-test between the posttest scores of the two groups showed a significant difference between the scores of the experimental group and those of the control group. The results demonstrated that Mnemosyne significantly improved students’ performance in vocabulary learning.
