This document discusses two approaches to teaching second language vocabulary: presenting words with bilingual glosses and/or organizing words into semantic field sets. It describes a study that compared the learning and retention rates of Japanese students in three conditions: words with bilingual glosses and organized sets (Group A), words with random bilingual glosses (Group B), and words alone in the target language (Group C). The study aimed to examine the effects of increased cognitive processing and improved lexical organization on vocabulary learning.
