How could you design an information system to support the interaction professor-students in the assignments review in an online education system? Please think in risks related for example cheating, wrong marks?
Answer
Designing an information system to facilitate the interaction between professors and students in an online education system requires careful consideration of various factors. The system should not only support the review of assignments but also address potential risks such as cheating and incorrect marking. To achieve this, the design of the system should incorporate appropriate technologies, user roles, entities, and interactions. In this analysis, we will outline the key steps involved in designing such a system and discuss the actors, entities, and interactions involved.
Step 1: Requirements Gathering
The first step in designing the system is to gather requirements by consulting with stakeholders, including professors, students, and administrators. This involves understanding their needs, expectations, and any existing challenges they face in the assignment review process. It is essential to identify the specific features and functionalities that the system should offer, such as online submission, plagiarism detection, and a mechanism for providing feedback.
Step 2: System Architecture Design
Based on the gathered requirements, the next step is to design the system’s architecture. This involves identifying the different components of the system, such as the user interface, database, and communication modules. One possible design is to adopt a client-server architecture, where the professors and students access the system through a web-based interface while the system components and data are stored on a server.
Step 3: User Roles and Access Control
To ensure secure and controlled access to the system, it is necessary to define user roles and implement access control mechanisms. In this case, the system would have two primary user roles: professors and students. Professors would have elevated privileges, allowing them to review and grade assignments, while students would be limited to submitting their assignments and accessing their grades.
Step 4: Assignment Submission and Plagiarism Detection
The system should provide a mechanism for students to submit their assignments electronically. This could be achieved through a designated submission portal, where students can upload their files. To mitigate the risk of cheating and plagiarism, an anti-plagiarism module can be integrated into the system. This module would compare the submitted assignments against a database of existing works, flagging instances of potential plagiarism for further review.
Step 5: Assignment Review and Feedback
Once the assignments have been submitted and checked for plagiarism, the system should facilitate the review process. Professors should be able to access and evaluate the assignments, assigning appropriate grades and providing feedback. This can be achieved through a user-friendly interface that allows professors to view, assess, and comment on each student’s work. The system should also support communication between professors and students, enabling them to ask questions or seek clarifications regarding the assignments.
In terms of interactions, the system would facilitate a two-way communication channel between professors and students. Professors can initiate interactions by providing feedback, grading assignments, and addressing student queries. Students, on the other hand, can submit their assignments, seek clarifications, and request additional feedback.
In conclusion, designing an information system to support the interaction between professors and students in an online education system requires careful consideration of various factors. By incorporating appropriate technologies, user roles, entities, and interactions, it is possible to develop a system that supports the review of assignments while addressing risks such as cheating and incorrect marking.
