Which way would be more effective in encouraging young people to study science? Many teenager students are uninterested in science, thus, few of them choose scientific degrees when they go to college. It is evident than some strategies are needed to reverse this trend. But, which measure would be more effective in encouraging young people to study science? Advertising could be a good choice, as it can be shown in diverse media to which teenagers pay great attention, as the television or the internet. Young people are strongly influenced by what they see on them, changing the way they dress, talk or even see life in general. However, only images of sport players or other famous people are shown. So, why not using the same strategy to create the same interest over young and successful scientists? On the other hand, school programmes are applied on the educative centers, where it is easier to reach the greater number of students. Not infrequently, what really hampers youngsters from being more interested in science is that they don’t really understand it. Other frequent reason is that teacher focus only into teaching science, but they neglect showing its applications. School programmes could be a great tool to remedy all these: they could reinforce the basis knowledge needed to understand more complicated principles and show them the practical and fun uses of science. In conclusion, advertising is a good strategy that could help to raise a positive view of science, while schools programmes could be more effective by acting directly on the root of the problem. So perhaps, priority should be given to the later.
