The analysis of the interviews came pretty handy respect to identifying the subjacent problems in the life of children, those that aren't mentioned at the moment but, after a further review, come to light. There were some of them that repeated in every other interview, such as the inability of parents to control what their children are using their smartphones for.
We, and every other group, presented our interviews to the teachers and got the opportunity to hear what they thought about it. This made us feel as most of what we'd done was pretty much useless. That's usually the feeling I got every time any student uttered a word while presenting in that class. But actually it was just some problems that weren't well defined, so that's was what we had to focus on for the week.
