Bilingual knowledge maps (BiK-maps) in second-language vocabulary learning

Bilingual knowledge maps (BiK-maps) were investigated as tools for learning German-English word pairs. Seventy-two undergraduate students participated in the 2-session experiment. They studied 32 word pairs in 1 of 4 conditio ns, each distinguished by the presentation format for the vocabulary: The I st group received BiK-maps (word pairs embedded in a spatial and semantic a rray); the 2nd group studied lists of word pairs; and the 3rd and 4th group s were identical to the Ist and 2nd groups except for the addition of seman tic emphasis materials. Free-recall, cued-recall, and multiple-choice tests were taken in Sessions 1 and 2 (48 hr later). BiK-map learners outperforme d list learners on all dependent measures. Semantic emphasis negatively aff ected performance over time.
