MOBILE APPLICATIONS

What is so important about mobile learning? It is not the device but the mobility of the learner that we can learn across different contexts, we can learn across different locations. So MALL is focusing on the mobility of a learner and on the notion of seamless learning, how you can connect learning from formal settings to more informal.
QR code
I don't like the idea to use QR codes in the process of education. Moreover I don't understand the purpose of the qr codes and I think that nowadays no one uses them. It has some pluses like it is a faster way to get information. But that's it. A lot smartphones don't have necessary tools or programs to read QR codes. But it may be a good variant if you take part in a quiz or game.

Quizlet
Quizlet is used by more than 50 million students and teachers each month, on the web as well as on iOS and Android. They’re found in classrooms where students play, as part of study sessions at home and in the hands of learners studying for everything from spelling tests to university science classes to professional certifications.

AUGMENTED REALITY

Like QR codes, augmented reality is a question for discussin. I don't think that it's a good idea to use this app as a lesson won't have any productivity. It will be just a funny game. maybe I sound quite sceptical, but in my opinion a classic lesson is more effective than such digital tools.
