First of all, I sincerely thank the teacher for providing us with such an opportunity to exercise ourselves. After four weeks of study, this course design is coming to an end. Generally speaking, the learning gains of this course are quite great. Looking back on the curriculum design during this period, I still feel deeply. Indeed, from the selection of materials to the production, from theory to practice, it can be said that in the surrounding training days, bitterness is greater than sweetness, but you can learn a lot, and at the same time, you can not only consolidate the knowledge you have learned before, but also learn a lot of knowledge that you have not learned in books.
Through this course design, we all know more about the importance of combining theory with practice. Theoretical knowledge is not enough. Only by combining theoretical knowledge with practice and drawing conclusions from practice can we truly serve the society and improve our practical ability and independent thinking ability. In the process of design, I encountered many problems, which can be said to be full of difficulties, and found many shortcomings in the process of design. I found that my understanding of what I learned was not deep enough and my grasp was not firm enough, which needed to be strengthened.
Life is like this. Sweat indicates the result, but it also bears witness to the harvest. Labor is an eternal topic of human existence and life. Only through practical training can we really realize it? Struggle hard? The true meaning of this word. I want to say that design is a bit hard, but it is also fun. In today's single theoretical study, there are few opportunities for practice, but we can. Moreover, design is also the task of a team. Working together can make us talk and laugh, help each other, cooperate tacitly, and how much joy is spilled here. I want to say that I was really tired in the past, but I was inevitably excited when I saw the fruits of my labor. Maybe some people don't like this kind of work, maybe some people think programming is a bit boring, but we think that no matter what we do, as long as people's lives are meaningful, this is also the most important. Society needs us, and we can work for it.
Our work is the work of the team, and the team needs individuals, and individuals cannot do without the team. We must carry forward the spirit of unity and cooperation, and the departure of one person may lead to the failure of the whole work. It is not enough for only one person in the training to know the principle. Everyone must know, otherwise one person's mistake may lead to the failure of the whole project. Unity and cooperation is a very important guarantee for the success of our training. And this internship just trained us, which is also very valuable.
Although our curriculum design completed the task on time within the specified time, due to the lack of knowledge and experience, the development function of the whole system is still not perfect, and we encountered many difficulties in the design process. For example, due to the lack of demand analysis in the early stage, it brought great difficulties to the concrete realization of the later system, so we did some useless work, but through our unremitting efforts and the help of teachers and classmates, we successfully completed the design on time, so we can only rely on our own strength.
The basic purpose of the curriculum design arranged by the teacher is to further improve ideological consciousness, especially the practical working ability of observing, analyzing and solving problems, and cultivate high-quality talents who can actively adapt to the needs of socialist modernization through the combination of theory and practice and interpersonal communication. After four weeks of course design, we generally feel that not only the practical ability has been improved, but more importantly, through the understanding of the software development process, we have further stimulated our interest in learning professional knowledge and can conduct more in-depth study in the professional field in combination with practical problems.
As an integral part of the whole learning system, an important function of curriculum design is to test learning results with learning results. Using the learning results, the system theory knowledge learned in class is tentatively applied to practical work, and some targeted suggestions and ideas are put forward for the modernization of design work from a theoretical height. Test the learning effect, see how far the classroom learning is from the actual work, and find out the shortcomings in learning through comprehensive analysis, so as to provide practical basis for improving the learning plan and changing the learning content and methods.
For our software majors, the cultivation of practical ability is very important, and it is not enough to cultivate this practical ability only by classroom teaching, so we must move from classroom to practice. Through curriculum design, let us find out the gap between our own situation and actual needs, supplement relevant knowledge in time in future study, and make full knowledge and ability preparations for job hunting and formal work, thus shortening the psychological transition period from campus to society.
This course design has achieved the expected purpose of professional learning. After the course design, we all feel that not only the practical ability has been improved, but more importantly, through the understanding of software development and software management process, our interest in professional knowledge has been further stimulated, and we can conduct more in-depth study in the professional field in combination with practical problems.
As for the design of this course, although our design is not perfect, many functions cannot be realized because of the limitation of time and knowledge level, but at least it has been greatly improved on the basis of students at ordinary times, and I firmly believe that it will have a positive impact on our future work.
In this course design, we have learned many things that we can't learn in class, such as the ability to think and solve problems independently, the ability to improvise when mistakes occur, and the ability to improve in cooperation with others, which greatly improve our practical ability and are of great help to our future work and study. It is important for us to acquire knowledge, but the spiritual gain is more gratifying. Frustration is a kind of wealth, and experience is a kind of possession. This training will definitely become a very beautiful memory of our life journey!

By studying the course of DSP, we all know that DSP is actually a kind of single chip microcomputer, which also integrates the central processing unit, control unit and peripheral devices on one chip. However, DSP is different from ordinary single chip microcomputer. It adopts multi-group bus technology to realize parallel operation mechanism, which greatly improves the operation speed and provides a very flexible instruction system.
This course design began after we finished the course design of single chip microcomputer. In fact, when we set up the course of single chip microcomputer, we began to prepare design materials. According to the design requirements, it took a week to design step by step. Every day we have a meeting in a fixed classroom to arrange the design tasks of the day, and everyone has a clear division of labor. And my division of labor is to weld the circuit board with the other two players according to the circuit diagram drawn in advance. The work looks easy. After all, when we were freshmen, we also did an electronic process internship similar to soldering circuit boards. So I thought it would be handy, but it was because of the smell of contempt in it that my later works fell short and I had to start all over again.
At the beginning of welding, we made a mistake in the overall layout. At first, we thought that a main chip would be soldered on the circuit board, so our chip layout was relatively concentrated, which directly led to difficulties in wiring later, but in order to avoid more troubles, we continued. At that time, a basic common sense was completely ignored, that is, using too dense connection mode in the case of direct connection with flying wires like this is not only not easy to weld, but also has poor electrical performance, which is likely to lead to short circuit and strong electronic interference.
In this way, we completed the preliminary welding of the circuit board in the next week. Just as we happily took it to do the experiment, the result was that the indicator light didn't respond, and we were at a loss. What is the reason? Check it! So we started a careful inspection in the afternoon. Needless to say, our team carefully checked according to the circuit diagram and found several obvious mistakes, especially that several capacitors were not grounded. This kind of low-level mistake really shouldn't be made. When we see this mistake ourselves, we all think it is very wrong, but it is good to know it and correct it. We quickly corrected this mistake. So I took it for testing for the second time. I didn't expect the problem to be more serious this time. The light-emitting diode emits a puff of smoke and burns directly. We were caught off guard and had to come back for inspection.
After inspection, we found that our circuit diagrams were all wrong. It turns out that we directly connect the LED to the 12V power supply, so it's strange not to burn it. After these two mistakes, we summed up our own mistakes, most of which were very low-level mistakes, which were really caused by our carelessness. So we checked the circuit board carefully again and found several short circuits. But because the overall arrangement was not made at the beginning, it can't be changed now. Finally, after our unanimous discussion, we finally decided to simply reinvent the wheel and re-weld the power amplifier module as a whole. This may be slow, but it is correct, but it is actually a helpless move. If it hadn't been for the poor welding that caused many problems, we wouldn't have to start all over again now, but fortunately, after we accepted this painful lesson, we finally understood a truth. We must do our own work in a down-to-earth manner, especially in our major, and we must not be careless at all. We'd rather start all over again than hand in anything that was accidentally made! Under this belief, we were busy until seven o'clock in the evening, and finally finished the welding again. To be on the safe side, we checked the system again. Finally, after making sure that there were no problems, we finally walked out of the classroom door and went to the cafeteria for dinner. At that moment, I felt that the food in the canteen was much more delicious than usual. Hehe, this is probably the so-called self-achievement.
Through this course design, I understand that one thing must be done seriously, otherwise a simple thing will not be done well, and there must be a spirit of doubt. We burned the diode this time because we were too superstitious about the circuit diagram we designed and didn't notice the obvious design mistakes, which led to this result. I hope that there will be more curriculum designs for us to exercise in the future, so that we can be more competitive when we go to society in the future. I will cherish such learning opportunities more in the future!

Second, the title description
Personnel management is an important part of enterprise information management. Faced with a large number of personnel and salary information, the financial department will waste a lot of time, manpower and material resources by using manpower processing, and the accuracy of the data is low. Therefore, it is very important to develop a personnel salary management software with friendly interface and simple operation for automatic processing, which is also the purpose and significance of this system development.
The development of the system has brought about a qualitative leap in work efficiency, mainly in the following aspects: the operation of the system can replace manual work to complete many complex tasks; Secondly, the operation of this system can save a lot of resources; Thirdly, the operation of the system can greatly improve the work efficiency; Fourthly, the system can make sensitive files more secure. Fifth, this system is economically feasible.
1, basic idea
Design interface with VB, write code, and realize functions such as query, deletion, modification and addition by calling SQL database in VB.
2. Work objectives
1 Input, modify, query and print personnel information.
Employee information is recorded in the database, which can be viewed at any time, playing the role of a file, and the employee information is registered, which is convenient for management. According to the writing habits of personnel and labor management personnel, the system can record basic information such as employee number, employee name, gender, department, professional title and highest education. For convenience, the function of notes has been added, which can describe the comments and characteristics of employees. After the information is entered, a detailed and easy-to-operate personnel file table will be automatically generated, which can record and understand the employee information of the company at any time at a glance. This system supports any input method.
2 salary management input, I, modify, query, calculation, statistics
Salary information mainly includes employees' basic salary, subsidies, bonuses, overtime pay, housing subsidies, pensions, etc. In addition, the system will automatically count the total wages of employees and other information.
3 all kinds of information query statistics
Query can improve work efficiency, input characters can get qualified information, and statistics can separate effective data from messy data.
4 system data security, set up system users.
In order to distinguish identities, the system consists of users, passwords and levels, so that the system can verify identities in the login interface of the system, compare the input information with the user table, and let the users who meet the identities pass the verification.
Third, performance.
1, personal main work
I work with other team members to conduct system analysis, business process analysis, draw data flow diagrams and write data dictionaries. In the process of system design, work with them to design new system functions, design E-R diagram, input and output design. In the second process, the respective tasks are planned and assigned, and the matters needing attention in the process of designing and drawing E-R diagram are reminded. When you encounter problems, ask your classmates and teachers for advice and solve them in time. In the process of system implementation, design modules and write programs. When debugging, correct the corresponding errors.
2, the main harvest
Curriculum design experience
After two weeks of course design, I have a lot of experience, including single chip microcomputer and more about the relationship between people.
With my own efforts and the help of teachers and classmates, I finally completed the whole system and realized the predetermined functions. I didn't learn the previous SQL language well, and the initial program drove me crazy. then
After several days and nights of hard work, I finally got a clue, and then with the help of my classmates, I found some reference books. With this book, I learned about various methods of system design, problems that often appear in the process of writing, and solutions. Next is the welding of the programming part. I didn't expect this seemingly unskilled job to be very laborious. Many times, I get up in the morning to buy a bottle of water and put something to eat in the dormitory. It takes a day to soak. I see many people, like me, discussing and studying together in twos and threes. At this time, there are also many people who help me or enthusiastically help me bring food. Everyone encouraged me to stick to it even if I couldn't produce anything in the end. When I wanted to give up, I told myself that even if what you made was defective or even unqualified, you should take out a finished product.
After more than a week, our program was finally completed and we can use it together. Although there were some problems in the debugging of the computer room, they were all solved. Finally, I found that I was a little interested in programming. I wanted to buy something to do after my winter vacation, and then make up the assembly language.
Article 4
In the first week of school, I participated in the database course design organized by the college. This task is completed by grouping and division of labor. There are five members in our group. They are the last five students in our class. I am honored to be recommended as the leader of our group. Smart? Under the guidance of all the team members, the task was completed a little earlier than we expected and a little more beautiful than we expected. We are very happy and proud.
Grandma's time to sell melons is over. Let's get down to business. Everything should be summed up. The following is my experience in this course design.
First of all, let me analyze the success of the successful completion of our mission and summarize some experiences for future reflection.
Everything is prepared in advance, and it will be wasted if it is not prepared. This is my motto and one of the old sayings that I deeply understand. At the beginning of this project, the teacher asked us to make a timetable. I made good use of this opportunity and spent a lot of time making a detailed timetable. After that, the tasks of our group were completed strictly according to this timetable. Of course, I learned about other groups later. One of the most important reasons why some groups' schedules are not perfect is that they have no idea about this week's database course design. There are many reasons for this phenomenon, one is that the foundation is too poor to understand the tasks assigned by teachers (of course, there are fewer such people), and the other is the lack of communication, including intra-group communication, inter-group communication and even communication with teachers, which leads to my second experience.
Communicate more, this is my second experience of this project. For this kind of project, communication between team members is extremely necessary. If team members can't communicate well, they will not only do a lot of useless work, but also do a lot of repetitive work. Good communication between team members, showing what they are doing and what to do next, so that the work can be carried out well. Our group did it this time. We will communicate or meet each other on qq every day and modify the schedule in time. In addition, we also help each other solve problems, or solve problems together. For example, in the design of this conceptual model, the classmate in charge of conceptual data model design (Zhao # #) and the classmate in charge of data demand analysis (left # #) in our group often communicate (because their tasks are closely related). * * * Only by solving problems together can we make a data conceptual model and beautiful data that satisfy team members. Of course, the most important thing is that we often communicate with teachers, and teachers also give many valuable opinions in key design places. Of course, what has to be reviewed is that the team leader has less communication with the teacher this time, but it is not as good as the team members. I hope to make some changes in the next project and play a leading role. I have also observed the completion of other groups and found that some groups have the phenomenon of team leader responsibility system or team leader responsibility system and individual team members responsibility system. I think the main responsibility for this terrible phenomenon lies with team leaders. The task of the team leader is not only to participate in some tasks, but also to assign tasks and coordinate the relationship between groups. This is a major communication channel. Generally speaking, the group leader should contact the teacher, communicate with other groups in the middle, and actively communicate with the team members in the middle. I think this is also the necessity of setting up the role of team leader. I sincerely hope that this phenomenon will not happen again in our next innovative course j2ee training. Everyone has an equal opportunity to get exercise. Team leaders do not seriously assign tasks and actively communicate with team members, which deprives team members of the opportunity to get exercise to some extent. More sadly, many team members have not realized this.
More active, this has many similarities with the previous communication, but I specifically listed it to reflect its importance. On the one hand, being more active means thinking and solving problems actively. Many students are eager to learn and always communicate with others, which seems to be very active. But a careful analysis of his questions is really sweaty. Some problems are similar to complaints, which can be solved with a little brain, but they never look for a solution to the problem before asking a problem filtered by the brain. To put it bluntly, they don't have a slightly mature view of anything. I once made a mistake in this respect. Now I recall those years, and I was really moved to tears by the patience of some students. It was not until one day that Mr. Zhang talked to me once that I suddenly realized that after that, I had made progress in teaching and at least became more able to ask questions. Of course, I think this is still worthy of a certain degree of affirmation. At least he is willing to learn, compared with that kind of love? Hitchhiking? Our classmates are much better. I mentioned the problem of depriving team members of the right to exercise. Some team leaders will have a lot of opinions when they read it. The team leader will say: do you think I like to do it alone, or am I forced? . This kind of situation is also what their group likes? Hitchhiking? The number of people is too large, which also reflects the extreme lack of team awareness of the members and leaders of the group to some extent. It's far away again. You like it anyway? Hitchhiking? Those students should be vigilant. Seeing that there is still one year to go out for internship, they still don't take the time to take the initiative to learn something, and they always let the team leader deprive you of the opportunity to get exercise. How will you get along on this road in the future?
The above three simple points have enabled our team to successfully complete the task in this design. Let's talk about the shortcomings of our group in this task first.
First of all, I have to talk about the team leader himself. I just mentioned that the lack of communication between the team leader and the teacher is the first point. Second, the team leader has always been an old problem, that is, the foundation is not solid, and many database theoretical knowledge is forgotten after the exam. At the beginning of the project, I had to rework some database knowledge, as most of our team members did, even many students in the class did. Therefore, we must firmly grasp the important professional basic courses in the future, and we must not pursue all courses. But then again, the team leader's rework is quite effective. He quickly understood the design task and made a detailed timetable as soon as possible, which needs to be encouraged. The third point is that team leaders lack perfect pursuit of the degree of problem solving. Generally speaking, he does not ask for a good solution. In fact, in our design model, there are some places that can be adjusted, and the integrity and rationality of the data will be further improved. If I lead the team members to work harder in this direction, the level will not only improve several grades, but also the team leader encourages the team members to solve some of them, and some places have indeed changed.
Secondly, talk about team members. Two of these players have worked with the team leader once, and the tacit understanding is not bad. They played a great role in accomplishing this task. They are Zhou # and Zuo # #, who are responsible for the compilation of functional requirements specification and data requirements analysis specification respectively. At the first group meeting, they said that they must hand over the works that made the team leader very satisfied, and it was indeed the case. They all did very well. The other two students are a little less active, and always spend time urging the team leader to finish the task reluctantly, which makes the team leader very headache, but on the whole, they are still very cooperative, but it also leads to great differences in the level of the team members to some extent.
What should I do? There are really few shortcomings. Maybe the team leader didn't reflect enough. Let's think it over and talk to the teacher.
chapter five
7. 1 Summary of course design content
According to the requirements of the task book and the actual situation of the library project of China University of Mining and Technology, this course design comprehensively introduces the project management, bidding planning and construction process management. Specifically, establish the owner's project management organization and refine the division of labor and responsibilities of various functional departments; By discussing the characteristics of various contracting modes and contract pricing methods, and combining with the actual situation of the library project of China University of Mining and Technology, the reasonable contracting mode and contract pricing method are selected. Choose a reasonable bidding method, and describe the time process of the whole bidding activity with crossing chart and flow chart. The work in the construction preparation process and the management measures of the owner to the contractor are compiled. The quality measures among the three control objectives in the construction stage are emphatically introduced.
7.2 Curriculum design experience
The hardest part is actually in the beginning Yes, when I really experienced curriculum design for the first time, I was a little helpless and even more at a loss. Find a template to know something about curriculum design. It is not a complete textbook theory, but a reasonable combination of theory and practice. Only by deeply understanding the theory can we give full play to its essential role and realize the perfect combination with practice. The course design process is an experience as well as an exercise. During this period, I realized how narrow my knowledge was. I need to read a lot of materials in the library to further increase my knowledge reserve and establish a complete construction project management and planning system. At the same time, this is also my further study and understanding of the theory of construction project management and planning, such as the specific time regulation in the bidding law, which I have never been exposed to before. Through compiling the crossing map of bidding activities, we have a thorough understanding of it. Exercised my ability to quickly collect information and use knowledge. In the process of course design, I encountered problems that I couldn't solve or felt very confused. Teacher Xu Na and my classmates gave me a lot of advice. I should sincerely thank them for their help, so that I can successfully complete the course design task on time. Of course, due to the limitation of my knowledge, practical experience and time, the curriculum design needs to be improved. I need to continue to study project management courses and constantly improve my ability!
