摘要

The purpose of this study was to figure out how much receptive vocabulary of English words the student of Nagaoka National College of Technology (NNCT) (N=578) who were 15 to 18 years old had by utilizing the Vocabulary Size Test (VST) created by Mochizuki (1998), and to compare the results of VST and the scores of their GTEC (Global Test for English Communication) to the extent of their reading, listening, and writing skills. The result showed that the first year students had the average of about 2,126 words, the second year students had about 2,602 words, and the third year students had about 2,630 words. Moreover, the correlation coefficient between the VST scores and the GTEC scores was calculated to find out that the participants' receptive vocabulary size was correlated more likely with their reading skills (r=.473) compared to the other two skills.
