Abstract:

We propose a block chain technique based on learning output. Firstly, based on the graduation requirements of professional certification colleges and universities, we establish a smart contract for achievement evaluation. Based on the grades, processes and data, through learning outcomes and smart contracts, we conduct a quantitative and qualitative analysis on the learning output, which is then recorded in the Merkel tree. Only the students who can complete the smart contract through the completion of the course can achieve social consensus, and thus obtain the explicit record of the transformation from the assessment for  curriculum completion to the competence evaluation after work. Moreover, the students' capability evaluation can serve as a feedback for the curriculum, thus realizing a continuous improvement.

Key words: engineering education learning outcome, block chain, smart contract, Meckel tree
