Three vocabulary learning approaches -- rote memorization; Cover, Copy, Compare (CCC); and Cover, Copy, Compare Adapted with picture (CCCA) -- were examined for effectiveness in promoting long-term memory retention for productive vocabulary in foreign language learning. Pretest, posttest, and delayed posttest data were collected using Conjuguemos, an on-line Spanish program. Results indicated a significant increase in mean scores with each assessment for all treatments; however, there was no significant difference in recall among the three learning approaches. Students were also surveyed about their preferences in approaches. Although survey responses indicated a preference for CCC, most students reported abandoning use of this method after six months.
