ClassDojo added new features to their digital portfolio tools for students and teachers. The highlight of those was the option for students to select the items that they want included in their portfolios. ClassDojo calls these student-led portfolios. Today, ClassDojo added a new way for students to sign into their portfolios.
Beginning today every student on your ClassDojo roster has his or her own unique QR code. You can print these QR codes and give them to your students to scan to sign into their individual accounts. Of course, this all assumes that a student doesn't then lose the printed code and or doesn't scan his/her classmate's code.
