What Are The Typical Applications Of Blockchain In The Field Of Education?

At present, the application of blockchain in the field of education mainly includes the following aspects.

Solve the problem of multi-party sharing and verification of education-related information

The most important application of blockchain technology in the field of education is to solve the problem of multi-party sharing and verification of education-related information. Early blockchain education network applications mainly focused on the certification of certificates and degrees, and were mostly based on the Bitcoin blockchain network. These efforts include the "Digital Certificate Project" of the Massachusetts Institute of Technology in the United States and the degree certification project of CESYT College in Argentina. Educational network blockchain applications that require globalization across different management domains across countries often use consortium chain type blockchain networks. The European Credit Conversion Accumulation System Platform is currently the most typical and successful case in this regard. It was first implemented based on the ARK blockchain platform, and later new versions were based on the Ethereum platform.

The credit conversion system proposed by Indian researchers is another follow-up work, and its prototype is also based on the ARK blockchain platform. In the block structure, transaction information can contain external links to more detailed credit and certificate information, in addition to the information of the sender and receiver and the tokens representing the credit. This information is stored on the respective higher education institution's own servers. Each higher education institution can choose whether to include optional detail links in transactional messages.

Learning process tracking, motivation and learning path shaping

Several universities in Hong Kong, China, have built conceptual models of “word-ing” blockchain digital learning systems based on Ethereum that can track the learning process. Yuan Wenze Blog In order to increase learning participation, the system can use smart contract technology to provide additional virtual currency rewards to top-ranked learners based on the incentive strategy deployed in the blockchain. These virtual currencies can be used to purchase some paid items or encrypted files, which can avoid plagiarism and protect intellectual property rights. The authors also use the ISO 9126 quality model to verify the functional improvements, usability, and maintainability of the proposed blockchain digital learning system.

Learning assessment

In higher education, it is an important task to evaluate students' learning status through experiments, tests, and examinations. But the problem is that assessments can be opaque and unfair, and their results can be deliberately altered. Applying blockchain technology for learning assessment can effectively solve these problems. The data stored in the block, in addition to regular content such as course names and course weights, also includes the names of various graduation requirements used as the basis for evaluation, and the resulting course learning output value, which is a combination of students' academic performance. Determine performance, learning processes and evidence of learning through comprehensive evaluation using quantitative and qualitative methods. In this way, the traditional assessment based solely on students' course performance credits can be upgraded to an assessment based on course learning performance based on the ability indicators required for graduation. A consensus mechanism is adopted to ensure that course evaluation is not restricted by teachers’ subjective wishes, thereby ensuring the persuasiveness of the evaluation results.
