Copyright © 2019 CCC-TIES All rights reserved. 5 Experimental results  Effect of learning support system based on learning economy  Externalize know-how and tacit knowledge  Virtual currency as an indicator for proactiveness ▸ Evaluation of learning outcomes  Virtual currency motivates learning ▸ Motivation
  6. 6. Copyright © 2019 CCC-TIES All rights reserved. 6 The Challenge of LEM  Challenge  Takes time to assure the quality of the knowledge in the market  Solution  Provide well thought out competency- based learning (CBL)

  8. 8. Copyright © 2019 CCC-TIES All rights reserved. 8 Research for competency graph structure  Specimen : iCompetency Dictionary (iCD) ▸ A freely available competency dictionary ▸ Consists of 4,500 task dictionaries ▸ 10,000 skill dictionaries included ▸ Created for human IT development ▸ Established by the Information Processing Agency Japan.  Validation issues  Examination of iCD parameter of property  Finding the graph structure peculiar to competency
  9. 9. Copyright © 2019 CCC-TIES All rights reserved. 9 Bipartite graph Task-nodes(n=639) Skill-nodes(n=491) • Edges concentrate on specific nodes Edges
  10. 10. Copyright © 2019 CCC-TIES All rights reserved. 10 Order distribution Task-nodes Skill-nodes Degree: Number of edges connected to the node Hub Hub
  11. 11. Copyright © 2019 CCC-TIES All rights reserved. 11 Power distribution Scale-free network structure R2=0.75,5.40-1.20log(x) R2=0.78,5.13-1.27log(x) Task-nodes Skill-nodes
  12. 12. Copyright © 2019 CCC-TIES All rights reserved. 12 Discussion : Scale-free network  Complex network structure - GAFA, air traffics, Bacon numbers  Hub - Edges concentrate on specific nodes  Growing network - New nodes are likely to connect to hubs - Network structure is robust.
  13. 13. Copyright © 2019 CCC-TIES All rights reserved. 13 New nodes connect to existing hubs at a high rate 2014 version Task-nodes (n=639) Skill-nodes (n=491) Task-nodes (n=495) Skill-nodes (n=424) 2018 version New nodes added
  14. 14. Copyright © 2019 CCC-TIES All rights reserved. 14 Conclusion  Competency is the structure of a complex network  Task-Skill graph is scale-free  Small world of skills and tasks monograph  The centrality of the graph indicates the importance of competency  LEM using blockchain and CBL  LEM is not required teachers, just keep learners motivated  CBL in LEM can provide competencies tailored to learners' desired learning
