The methodological approach was the action research model where the process of producing news was followed from selecting news to reflecting on their learning outcomes. The knowledge from the pilot study is useful in designing active projects within the scope of media literacy. One of the learning outcomes for the girls in this study was the awareness of how news programs in TV are staged. A positive response was the initiative from one of the participating schools to start their own news project in one of the classes. A possible outcome in longer run projects is better knowledge for developing pedagogical tools in media education.展开更多
