The digital transformation of higher education demands effective and efficient methods for learning support and assessment of learning processes. This paper relates learning support and assessment to each other in the context of learning management systems. It refers to previous studies carried out in multiple introductory economic courses of the University of Applied Sciences Mittweida which examine possible connections between the use of digital tests and learning success, investigate student’s acceptance and self-perceived learning success with respect to the webbased portion of a blended course and a purely online based course. Based on a survey (n = 71) and a quantitative analysis (n = 214) with logging and exam assessment data, the previous work shows that students approached the web-based course portion with rather reserved attitudes. Still, they perceived the individual course elements, namely videos, podcasts, interactive worksheets, online tests, and a comprehensive PDF file to be beneficial to their learning experience. Especially we could indicate a positive correlation between the points students achieved in the online tests and the exam results.
This paper looks at current projects in the field of Blockchain in education, their specific areas of application, possible advantages and weaknesses. Three examples developed by the team of authors are introduced in detail. First: Gallery-Defender a Serious Game, which was adapted to serve as a demonstrator in a stand-alone version to show the possibility to carry out exams directly from within the game and store the grades and meta-data on Blockchain. Second: Art-Quiz, an e-learning tool, which can be integrated into existing LMS systems and map exam results and further data using Blockchain technologies. Both were developed following an iterative design process. And third: The results of a focus group, which simulated the assignment of grades after an oral online exam. The three examples presented here are based on the Blockchain system Ardor/Childchain Ignis, but each demonstrator has a different set of features and approaches.
In addition, the integration of various Blockchain solutions was conceptually designed to make a Multi-Chain model possible.
