? Report conception, writing requirements are: logical, clear; smooth and concise language, clear text print; illustrations are clear and accurate; text word count requirements of more than 10,000 words.
VIII. A few notes about the graduation design work
1. Hiring Instructors
Hire instructors with the assistance of the relevant teaching stations. Instructors should be engineers or above, and there can be more than one instructor, or a group of instructors. Instructors are responsible for guiding students to write the main content of the graduation design mission statement and guiding students to write the graduation design thesis.
2. Writing the mission statement
The mission statement of graduation design should be completed under the guidance of the instructor. Within the specified time, it should be submitted to the main teaching station or off-campus learning center for examination and stamping, and then sent to the North Post Online College for approval. If the mission statement is qualified, you can continue to write your thesis. The approval of the mission statement will be announced online. If it is not qualified, you should make changes according to the requirements for approval of the mission statement and repeat the above work within the specified time.
If the mission statement is not approved within the specified time, the completion of the thesis will only be postponed for half a year with the next due student.
There can be no case of multiple task books on the same topic for the same student, and if such a problem occurs, it will be regarded as a cancellation of this graduation project.
3, graduation design report
Can not change the thesis title without authorization, that is, the thesis title is consistent with the title of the task book. If you really need to change the title, you should apply in advance and be approved by the main teaching station or off-campus learning center before you can send it to the Teaching Department of the Online College to re-execute the approval of the mission statement.
Students who are in a position to pass the mission statement should pay attention to the teacher's additional approval and reflect it in the thesis to ensure that the graduation design is completed according to the requirements of the mission statement.
No plagiarism of other people's articles or thesis, once detected, it is regarded as plagiarism treatment.
Can not copy the existing engineering design reports and other ready-made documents, the result is that the design content seems to be a lot, very comprehensive, but not my specific design content, such a thesis defense can not be passed.
About the graduation defense
I, the thesis defense procedures and preparation requirements
The thesis defense is the last part of the whole teaching process, but also a more critical one, I hope that all students seriously, well prepared, garden full of this last link.
1. Defense procedures:
①Personal narrative report on the main content and my work, focusing on my main design content, design ideas and the main results. Occupying 10-15 minutes;
The basic theories and concepts involved in the dissertation may not have to tell.
This session is to train and practice as a technical staff how to communicate technically, how to express their technical views. Requirements for this link is: telling the problem of logical, clear, concise language.
② by the defense teacher questions, the respondent to answer, in the defense process may also be additional questions, answer questions accounted for 20 minutes.
The main scope of the question is the content of the dissertation and the dissertation related to some of the basic knowledge of the subject matter of the question.
This section assesses the depth of mastery of the content of the design and the mastery of the relevant basic knowledge. This requires the designer to master the content of the design to a more in-depth degree, not just mastered some of the concepts of the skin or copied from other sources, so it will be difficult to answer the questions.
This requires a deeper understanding of the basics of what is involved in the paper, for example, some of the data and formulas must be quoted with a basis, and can explain their concepts. Another example is the design of some software and programs must be able to speak clearly about the design ideas and processes, and can explain the meaning and role of a certain section of the program.
2. Preparation requirements:
① Prepare a good personal narrative outline, and make a certain trial in order to grasp the time, to give you 15 minutes of time can not be more than, and I hope to make full use of, this is an opportunity to show their own.
2. Prepare wall charts, tables or computer presentations in advance
3. You are only allowed to refer to your thesis and the outline prepared by you, but not to other books and documents.
4. You should listen to the questions asked during the defense and understand them before answering. If you can't understand the question or you are not sure about the meaning of the question, you can ask the teacher to tell you the meaning of the question or give you some hints, but you can't answer the question without knowing the meaning of the question.
5. Don't be nervous and think calmly when answering.
II. Grading Criteria
Report score: 50 points Personal narrative: 10 points Answer the question: 40 points The total of the above three 100 points; 59 points or less for failing; 60-69 points for passing; 70-89 points for good; 90 points or more for excellent.?
