[Reader-list] Looking for Assamese-English bilingual materials

[Chintan]

Hello
Mahananda Pathak, a friend of mine, is looking for bilingual teaching
materials for regional medium Assamese children of classes 4 and 5 to teach
English. These bilingual materials could be books, word cards, posters,
reading cards, parallel texts, etc.
He is pursuing a Ph.D. in English Language Education at the English and
Foreign Languages University in Hyderabad.
His main research questions include:

Can bilingual teaching materials be exploited to develop early L2 reading
(English) skills of young Assamese children? If yes, how?

What are the different ways and possibilities of using L1-mediated reading
texts (Assamese) to develop early L2 reading skills (English) of young
children?
If you have any information or resources to share with Mahananda, please
mail him directly at mahanandap at gmail.com
Thanks a lot!
