It has been a recent phenomenom that has led teaching towards the needs and interests of students more than ever. Some of these innovations and changes have already been mentioned along this blog, and here we have a new one, QR (quick response) codes. They are a 'square composed of black modules on a white background with encoded information that can be scanned by web-connected smart phones' (Mallia, 2014). What they do is to open a file, a link, a video, or an image, playing the role of a Key that opens a door to somewhere else in the virtul world. The surprise effect that it can have on students, specially pre-teens, is great, and an excellent factor for meaningful learning. For example, you can create a treasure hunt by QR codes, and tell students that they are going to play a game with all the topics they have dealt with during the year , the week, the lesson, etc. The flexibility that this type of tool provides is amazing since you can customize it in the way that best fits your classroom. It is easy to use and create, but the only drawback is that you need to have internet connection in order to open a link, that is, a website.
So having stated the advantages and disadvantages of this innovation in the classrooms, we could say that it worths trying and looking at the effect it could have on our students. Because teaching shouldn't be related to make students memorizing words, phrases and grammatical items but it should help them learn in a better quality and more innovative way.
