The second principle I propose is related to vocabulary development and glosses. As it can be concluded from the various research studies presented above, one great way to increase vocabulary acquisition and retention is the use of computerized reading passages enhanced with various types of glosses. As research has suggested, multimedia glossing triggers better results when compared to print glosses. Moreover, full glossing seems to be the best facilitator of vocabulary acquisition and reading comprehension, as opposed to little or non-glossed texts. In addition, best results in retention are triggered by picture + text annotations, whereas pronunciation, video, and audio glosses seem to correlate negatively with reading comprehension. Multimedia glossing is, however, a valuable tool that can assist in vocabulary acquisition and recall, as well as in reading proficiency and should, therefore, be integrated by TESOL instructors in their vocabulary and reading classes
