Demand Analysis Model of Coursework Management System NABCD
N——Need
The difficulty of handing in assignments and the tediousness of reviewing are the pain points that exist in all large-scale courses of the University of Science and Technology of China.
At present, teachers either use mailboxes or paper assignments to submit, and these tools and platforms all have certain problems.
And our online coursework management system is proposed to be developed based on such a demand background.
A——Approach
This website seems to have a very simple function, but it is not easy to implement it through code.
HTML can be used to build a website structure. The difficulty lies in how to build a database, store course materials, course members, and provide it to teachers and students to query the status of homework submissions.
The online preview function may be difficult to build by yourself, and you may need to use modules already built by others.
The designed interface is introduced later. After careful sorting, I feel that the workload is relatively large to achieve.
B——Benefit
Less is more, which is our main feature. The goal is to create a system that is easy to operate and stable.
This website provides an assignment submission system that is convenient for both teachers and students.
Students can check homework requirements online, submit homework documents, and check homework submission status according to their own time.
Teachers do not need to download the homework themselves, they can check the homework through the online preview.
Teachers do not have to face the crowded mailbox space, nor do they need to count the number of submissions by themselves, and remind the members who have not turned in their homework, so as to easily manage the homework of the course.
C——Competitors
Locally, the software made based on the school situation is more in line with the needs of the school.
Compared with the current method of handing over most of the work, our solution has the advantages of being simpler, more convenient and faster.
Compared with the pros and cons of the existing homework submission software at this stage, such as the homework submission in Blog Park, and the sub-transaction submission platform.
All of our solutions can be improved (the pros and cons will be analyzed later).
D——Delivery
We can spread it through visits and QQ groups.
Email teachers, etc. to promote our website.
If our website really has a much more powerful performance than the current method of handing in homework, I believe its dissemination among teachers is not a problem.
To promote to other schools, spread it through discussions and social media.
Specific competitive analysis:
1. Blog Park
Advantages: 1. Simple operation and concise UI.
2. There is an email reminder function after each job is released.
3. It is convenient to count the submitted and unsubmitted lists of homework
Disadvantages: 1. The content of the assignment and the final score are open to all students, lacking privacy.
2. Assignments are submitted in the form of blog posts. Although pictures, etc. can be inserted into blog posts, the format of assignments that can be submitted is relatively simple.
3. The way of feedback between teachers and students on homework is through blog post comments, which is not direct enough.
4. Before the deadline, the assignments that have been submitted to the assignment list can be modified arbitrarily.
2. Divide easy
Advantages: There are WeChat public account and web version, based on the characteristics of WeChat, the communication between teachers, teaching assistants and students is more convenient and efficient.
Disadvantage: The function is too complicated.
After the comparison, we combined the teachers' demand for different functions in the questionnaire, separated the teacher side from the student side, absorbed the advantages of the blog garden, and achieved breakthroughs in some important functions, such as providing online homework preview, scoring and commenting function.
The following are our design ideas for the basic framework of the website:
