The purpose of this paper was to study the effects of applying computer assisted instruction (CAI), in this case, LIVE ABC on college freshmen’s English vocabulary development. Two groups (high-proficiency and low-proficiency) of college freshmen from Chienkuo Technology University were used in the study. Each group comprised 50 students (totally 52 male and 48 female). This study was conducted in the fall semester of 2012-2013 and lasted for 18 weeks. A pre-test was administrated at the beginning of the study and a post-test immediately after its completion. The study evaluated student performance using scores on individual semester tests (pre-test and post-test). In addition, a questionnaire was developed to assist the study. The research method applied Grey Relational Model to analyze the assembled data and decide on an effectiveness rating. The major findings of the study were: Where students used computer-assisted learning in vocabulary building their test results were generally better. Low-proficiency students benefit more from CAI than high-proficiency students. All students develop greater fluency, more precise pronunciation and better word understanding. Looking at gender, female students benefited more than male students. The study also came up with some suggestions for further research in the future.
