Once you have found a first idea for the topic of the thesis, you should narrow this down more and formulate a concrete question. It is important to consider whether there is enough research literature on the topic chosen and whether it is relevant for one’s own degree program. If there is little or no basic research on the topic, it is not advisable to write a paper about it. Because in the few months that are available as processing time, you will hardly have the time to carry out extensive research.
The topic and the question should be discussed as early as possible with the supervisor. This can provide valuable tips for the structure of the work and assess whether the topic is appropriate for a bachelor thesis. It is helpful if you have well prepared a first rough outline for the conversation with the supervisor and the topic has already been limited as far as possible. This gives the lecturer the opportunity to make concrete suggestions and to contribute initial content tips.
