Candidate dissertation is always a qualification work. You are defending some kind of work in which you show your qualifications. This does not necessarily have to be a breakthrough direction in science and practice. However, sometimes this concept of work is somehow simplified. It is believed that if you wrote several formulas or 150 pages of reasoning, the qualification work is already ready and you can go to defend it, sometimes not all do this work, but simply order online services to write essays and scientific papers. However, it is not. In any case, the Ph.D. thesis should contain at least a new look at some well-known statements of problems or some new solutions. In this article, we will consider the issue of why people generally defend their theses.
Let us now turn to the most essential part of the process of writing a dissertation. The question is: who and how should the tasks be set? The graduate students and masters themselves cannot set tasks, this is a normal phenomenon, it is not necessary to be surprised at this and worry about it. The ability to set goals successfully comes with experience. In order to be able to set tasks well, you have to work hard. Therefore, we are confronted here with two problems: the choice of the supervisor of studies and the choice of the topic of the dissertation.
Choice of the supervisor of studies. So, advice. If you are not self-sufficient, never choose executives who do not have the time to deal with you. It is necessary to choose managers who have the time, opportunity and interest about you and your work. A graduate student or a master who are “taken for granted” turns out to be in a very bad situation precisely because they do not know how to set tasks.
Now about the tasks. There are tasks, problems and good intentions, that must be clearly distinguished. Karl Popper has wonderful words: “Science has no areas or branches of knowledge, in science there are unsolved problems and the need to solve them.”
What is the task in this situation? As I understand it, the task should clearly define what is given and what we intend to get and more, the solution of the problem. That is, the task is always specific, as in the school curriculum. An example is, say, data analysis using linear regression. You have an apparatus, you solve the problem and receive something. Another example, you have input data, you have a model that describes the behavior of participants, you need to find first-order conditions. This is the task.
The problem is a little bit different. It is known what is already given, but what we will get is far nobody knows. Moreover, the apparatus and technique are often unknown. They have to invent a problem or modify some existing ones. There is a great amount of books on topic whence there are problems and how they are solved.
