Research Abstract

This study examines whether Matrix model enables us to make a reasonable prediction about the second language vocabulary acquisition. This model uses the two sets of data and calculates the transitional probability of vocabulary knowledge changes. Based on the probability, we can make prediction about the future vocabulary acquisition. The study compared the prediction and the learners' actual vocabulary scores in order to determine the validity of the model. The study also used simulation to compare the change processes in terms of frequency of changes between simulated data and learners' actual data. The results showed the model can make a reasonably good prediction and simulations showed that we can also make a reasonably good prediction about the frequency of changes.
