Being able to get a doctorate from any university in the United States is equivalent to obtaining a certificate of academic status in your field. In the United States, you are likely to be admitted as a doctoral student, but you will not get a doctorate in the end. In this case, the doctoral supervisor will generally give a master's degree certificate in comfort.
Americans believe that doctoral education is specially used to train scientific research, academic and educational professionals. If you don't engage in the above occupations in the future, you don't have to go to the United States to study for a doctorate. If the doctoral supervisor thinks that it is not the above-mentioned "materials" and such a major, no matter how high the credits are, you will not get a doctorate. Therefore, getting a doctorate in the United States has many random elements. In addition to strength, you need some luck to some extent.
First of all, you should be very careful when choosing a school. Doctoral degrees in some American schools are particularly difficult to read, such as California Institute of Technology (here is Mr. Qian Xuesen's alma mater); For example, the University of Chicago (who won five Nobel Prizes) and new york University, both of which are difficult to study for doctors and masters, especially in the economics department; For example, at the University of California, Berkeley, some majors take 65,438+00 years to finish, because there are many students in China and the competition is fierce. The principal of the school is Mr. Tian Changlin, an American Chinese. There are also City University of new york, new york Bronckley Institute of Technology, etc. A big reason why new york University is difficult to study is that there are many employment opportunities in new york. Most people who go to new york or new york will choose employment, but once they choose to study in new york, they are high-quality talents. What are the famous schools in the United States that are not too difficult to learn? Duke University in Tennessee, Rice University in Texas, University of Illinois in Champaign, Illinois, etc. The Department of Electrical Engineering of the University of Illinois and Stanford University are neck and neck in the annual appraisal, ranking first and second in the United States. Its accounting department ranks first in the United States, and a graduate of the University of Illinois is the only person in the United States who won two Nobel Prizes.
Secondly, the award of doctoral degrees depends largely on the intuition of doctoral supervisors. He thinks that he is unlikely to make achievements in scientific research and higher education, so he will try his best to find fault with credits and doctoral thesis, saying that the thesis materials are insufficient, and so on, and it is difficult to get a doctorate in the end. The United States implements the doctoral qualification examination, the written examination is taken by the department, and the oral examination requires five full professors to take part. Three of them are from our department and two are from foreign departments (so-called professors of marginal subjects). Of course, the evaluation of the paper is mainly based on the guidance of the professor, and it must pass the test from the quality and quantity of the paper. Therefore, the reputation of doctoral tutors in this field plays an important role in whether they can successfully pass the doctoral degree examination, whether they worship themselves or are appointed by departments. Because the higher his (or her) academic prestige, the more trustworthy he (or she) is, and it is good that he (or she) can say yes; If the doctoral supervisor's academic status is average, he or she will be particularly critical of students' papers, on the one hand, he or she will show his or her self-confidence, on the other hand, he or she will be afraid of being told that he or she is too lax with students.
Finally, pay attention to the topic of the paper. If it is a natural science research paper, involving experimental reports and data, it is even more troublesome, and it needs to be carefully selected. Take this as an example. Mr. Li has a college classmate who studies genetics. His doctoral thesis materials need to extract immune vaccine from dairy sheep. It is difficult to guarantee the success rate of this immune vaccine every time. It takes at least seven to eight months from planting to harvesting. As a result, he spent a whole year doing two experiments, and all the sheep died, and then he did it again. Until a year and a half, the experimental data could not be produced, the experimental report could not be produced, and the doctoral thesis could not be produced. As a result, this classmate failed to get his doctoral thesis.
In a word, the reasons why you can get a doctorate in the United States are very complicated, and sometimes you can't fully prove your professional attainments. Therefore, you must correctly understand it and treat it.
