I am not sure how the trial is going take place. 1:1 laptop or traditional classroom environment? 1:1 would be fantastic.
I am also a little puzzled that the news reported the bilingual nature of iFlashbook. True, but many reference materials like the infamous 词语手册 (A complete series of reference books which contain vocabulary from textbooks) are already using English to explain meanings of Chinese words and phrases.
If interested, please read my review of this application.
