An Experimental Research on the Effects of Types of Glossing on Incidental Vocabulary Acquisition through Reading
A large amount of research has been conducted to delve into the means of improving the rate of incidental vocabulary acquisition through reading, which includes providing glosses or annotations, increasing the reoccurrence of the target words and taking the advantage of dictionaries. But little has been done on the effects of different types of glossing on incidental vocabulary acquisition through reading. The present study has been aimed at finding out whether the three different types of glossing, i.e. glossing in Chinese, glossing in English, and glossing in both Chinese and English, have different effects on enhancing the incidental vocabulary acquisition rate through reading. From the data analysis of the present study, it has been found that in terms of enhancing the depth of vocabulary knowledge in incidental vocabulary learning through reading, glossing in both Chinese and English is the most effective glossing type, whether it be in the immediate retention testing section or the delayed retention testing section. In terms of enhancing the breadth of vocabulary knowledge, glossing in Chinese is the most effective one in the immediate retention of the breadth of word knowledge, and glossing in both Chinese and English is the most effective in the delayed retention of the breadth of word knowledge. On the basis of these findings, implications and suggestions for the arena of foreign language teaching and other related fields have been proposed.
