Abstract
This study explores the use of blockchain in the course design and evaluation in Chinese universities, and explores the value of teachers’ views and experiences on blockchain in the course design. Previous studies have shown that blockchain has a positive effect on the improvement of online teaching management and evaluation quality. Most of the current research focuses on the management of online teaching by using blockchain, and this qualitative case study investigates the design and evaluation of online course based on blockchain by five teachers of different specialties. Semi-structured interviews and course materials were collected from five teachers for a TPACK framework analysis. The result of the survey emphasizes that the redesign of online courses based on blockchain can improve the matching between blockchain and courses, the quality of teaching and the trust of various parties in online education. The block chain-based the online course of both theory and practice design and evaluation, which is oriented by the index method of capability evaluation, is an appropriate idea and has achieved good results. The experimental course focuses on the integration of blockchain and experimental platform. The immersive and interactive course presentation and the personalized examination based on machine learning are effective. But follow-up should pay attention to the different requirements of course design of different disciplines, using a variety of data sources for analysis, to take measures to enhance the enthusiasm of teachers to adopt new technologies.
Highlights
With the development of digitization, network and global learning environment, online teaching, which integrates the Internet, intelligence, technology and transcends the limitation of time and space, has become the new normal of university teaching (Wu, 2020)
As far as research question 1 is concerned, the research shows that the method evaluation based on competency-oriented indicators can be considered. by using blockchain to design and evaluate online courses, while designing online courses based on blockchain is aimed at the discipline with strong theoretical and practical operability
This research shows that blockchain-based online course design is suitable to use a variety of teaching methods to obtain qualitative and quantitative process-based and outcome-based data, win the trust of multiple parties and enhance students’ learning effectiveness
Summary
With the development of digitization, network and global learning environment, online teaching, which integrates the Internet, intelligence, technology and transcends the limitation of time and space, has become the new normal of university teaching (Wu, 2020). The use of new technology to reform the teaching of courses has been the focus of educational research (Petersen & Hossein, 2016). From the early production of professional video, the use of drawing software, the live course(Koehler & Mishra, 2009), to the recent flipped classroom, massive open online course, etc., more and more researches focus on the improvement of teaching level and teaching quality brought by technology (Long et al, 2019; Downes, 2019)
