Oh easy OSS system ┃Build standardized computer experiment teaching platform
Problems faced by computer experiment teaching:
Computer science, as a discipline closely related to applications, can not be separated from a large number of teaching experiments in the teaching process, and other various majors also have corresponding auxiliary software, which requires teaching practice on the computer, then in high-cost IT hardware After investing, how can we ensure that the teaching experiment course achieves the desired effect?
With this question, we visited dozens of key universities and vocational schools across the country. Through in-depth exchanges with computer laboratory leaders and experts, we found that in the current practice of computer experiment teaching management, we mainly face the following problems:
1. With the continuous refinement of the branch of computer science, and more and more majors need to teach related auxiliary software, the requirements for the teaching experiment environment are becoming more and more complicated;
2. With the expansion and extension of teaching to the Internet, teaching platforms are facing increasingly prominent security threats;
3. With the proliferation of instant messaging and online games, it is increasingly difficult for students to concentrate on completing teaching experiments;
4. With the trend of centralized laboratory management, it is becoming more and more difficult for classroom teachers to master the process and results of teaching experiments;
5. No matter the teaching management department or teachers or students, there are increasingly higher requirements for the computer laboratory, but no system platform can meet the requirements of all parties and manage them in a unified manner.
These all affect the effect of computer experiment teaching, and then affect students' mastery of relevant knowledge.
Specific requirements of computer experiment teaching platform:
According to the problems faced by computer experiment teaching, computer laboratory management experts each put forward their own opinions. Everyone agreed that a good computer experiment teaching platform should meet the following six standards:
1. Ability to quickly deploy software environments for various complex experiment requirements
With the rapid development of computer technology and the construction of various disciplines and majors, more and more majors (curriculum) teaching have changed from the traditional classroom blackboard writing mode to the modern computer room multimedia mode, and from the rigid duck-filling teaching mode. It is a flexible interactive teaching mode. Along with this, higher requirements are placed on the experimental teaching software environment of the computer room: the experimental teaching environment provided by the computer room needs to meet the different needs of various majors (courses), such as the different needs of different majors for operating systems (Windows series Linux, Unix operating system), different classes of different departments need to wait for different versions of the same software, and at the same time, hundreds of computers in the computer room need to be deployed quickly and uniformly ... Therefore, a good computer experiment teaching platform must Able to quickly deploy software environments for various complex experiment requirements!
2. Can effectively prevent viruses and man-made damage, and protect the security of the software system
At present, various types of viruses and Trojans are emerging one after another. The school computer room is often used in many computer viruses because of frequent use and the number of students on the computer. In the course of computer lab teaching and experimentation, access to bad websites, infection using mobile storage devices such as U disks, and local area network transmission infections, etc., may cause the computer and the computer room to be infected with viruses, causing the computer to not be used normally. At the same time, some uninstallation, deletion, formatting and other operations that some students intentionally or unintentionally performed on the computer directly caused irreparable damage to the operating system and software environment, which seriously affected the normal use of other students. If these problems cannot be dealt with well, the computer experiment teaching cannot be carried out normally! Therefore, a good computer experiment teaching platform must be able to effectively prevent viruses and man-made damage, and protect the security of the software system!
3. Possess the ability to prevent network risks to ensure the smoothness of the network platform
With the continuous development of computer network technology, the application of the network has penetrated into every corner of society. The computer room of the university is equipped with a large number of computers. The computer teaching, experiment, and remote management and maintenance of the computer room are inseparable from the support of the network. Due to the openness, interoperability and other characteristics of the computer network, such as problems such as ARP attacks and network downloads at a node in the network, the entire network will be affected, resulting in various teaching, experimental tasks and management of the computer room , Maintenance work can not be carried out normally. Therefore, a good computer experiment teaching platform must have the ability to prevent network risks to ensure that the network platform is smooth!
4. Effectively control the students' behavior in the experiment class and ensure the teaching order
The computer room is a place for students to learn and experiment on the computer. In order to ensure a good computer order and teaching effect, the management department has formulated relevant computer room operation specifications. However, there are always some students who do things that are not related to learning and experiments when they are on the computer, such as playing games, reading novels, chatting with QQ, etc., which not only delays themselves, but also affects other students, disrupting the normal order of computer learning and experiments. The teaching effect of the experimental class is also affected. Therefore, a good computer experimental teaching platform must be able to effectively control the behavior of students in experimental classes and ensure the order of teaching!
5. Ability to monitor and count hardware assets to protect teaching resources
As an important part of the computer room, computers are also used as fixed assets of the school, and the management of relevant asset statistics needs to be carried out every year. Computers in the computer room are used frequently, and the aging and natural damage of various hardware devices occur from time to time. At the same time, some students have a strong desire to explore, which also leads to the problem of computer hardware loss in the computer room. For the hardware asset management of the computer room, the manual management method is not only a heavy workload, but also can not find the natural damage and man-made damage of the hardware assets in time. Therefore, a good computer experiment teaching platform must be able to monitor and count hardware assets and protect teaching resources!
6. Ability to monitor and count the experimental process and control the experimental effect
Since many computer experiment classes are now concentrated in centralized laboratories such as computing centers and training centers, it is often difficult for the instructors to understand what specific things students have done in the experiment classes, resulting in the inability to master the students ’experimental process and effects . On the other hand, if students access some sensitive content in the laboratory, laboratory managers often cannot find it in time. Therefore, we need to collect and statistics the students ’operations during the experiment, including network access data, so that the teacher can better grasp the performance of the students’ experimental class and understand the learning of excellent students during the experimental class. Ways to promote and improve teaching effectiveness. At the same time, the administrator can also effectively grasp the student's computer records, which is convenient for handling some violations. Therefore, a good computer experiment teaching platform must be able to monitor and count the experiment process and control the experiment effect!
