So the most difficult group to teach research are the beginning readers. For my school this is 1st and 2nd grade. Sure they can write sentences. Sure they can read information. However can they find sites, interpret information, and publish their work. It is difficult.
My solution (since one of the grades always explores different countries with each class taking a country) is Scholastic Digital Passport.
My recommendation is to NOT have the students login the first time they research their country. Just have students look at their country's site. (We do it by class.) Then the classroom teacher differentiates how they pull information and write it up. The attached document helps the students write their sentences and research at an age appropriate amount.
Once edited they can take this sheet and input into the site in one 45 minute session (if they come prepared.) This is important because the site requires a password for saving and since this is done individually students can sometimes make mistakes and lose work if it has to be done in multiple sessions.
The reward, however, is awesome. Students print their research into passports that include pictures from the country they are researching. The printout has space for the students to draw additional images of their country.
