In this section, we use marker-based augmented reality technologies to create teaching activities for improving music learning for students for the 5th grade.
Using marker-based codes for presenting additional information in a mobile device is very simple to use and straightforward. The teacher can use simple QR (Quick Response) two-dimensional codes for associating information such as text, URL or any other data. Quick response codes are much more popular than the other code formats and there are several sites where the teacher can easily create such codes.
We decided to use the Microsoft tags because for the example presented in figure 7 we want to use smaller codes that become less intrusive. Reading smaller Microsoft tags are more reliable then the equivalent QR codes.
Microsoft tags are also very easy to create, requiring only the registration at the site
http://tag.microsoft.com.
The example of figure 7 uses the Microsoft tags to show the answers to the different questions. We created other augmented reality documents with music sheets and like Beauchamp and Kennewell (2010) we also noted that the students were more interactive in the classroom, improving the learning process.
