look elegant when hung on the wall, but
they contain very little detail about what
the recipient learned.” (Young, 2012)

Open Badges form a loose federation of many small digital credentials.
“ Mozilla Open Badges is an initiative exploring
alternative ways for learners to receive recognition
for skills and achievements gained outside of the
school environment, such as open credentialing
and accreditation for all types of learning, including
informal and interest driven.

SOCIOLOGY OF CREDENTIALISM
“Credentials are (a) monopolized by competing
occupational status groups as exclusionary status, cultural
entry barriers to positions and (b) used by hiring parties as
measure of candidates’ trustworthiness in positions that
embody discretionary powers.” Brown (2001)
#RIDE2016 | UNIVERSITY OF LONDON | 11-04-2016 | CC BY-SA | ILONA BUCHEM
Open Badges can be issued
not only from
teacher to student,
but also
peer to peer,
student to teacher,
student to university,
teacher to university,
employer to employee,
employee to employer,
or even
me to myself.

DISRUPTING CREDENTIALING PRACTICE
Open Badges can help
learners to connect
diverse
learning contexts,
learning episodes,
learning outcomes,
by assembling
learning evidence
and creating
learning pathways.

“Some observers see a darker side,
though, charging that badges turn all
learning into a commodity, and thus
cheapen the difficult challenge of
mastering something new. Rather than
dive into an assignment out of curiosity,
many students might focus on an endless
pursuit of badges.” Young (2012)
OPEN CHALLENGES
#RIDE2016 | UNIVERSITY OF LONDON | 11-04-2016 | CC BY-SA | ILONA BUCHEM
“Combined data of multiple badges could
be used by web crawlers or data
companies to build individual profiles of
learners, including what content they
would like to purchase, what specific
skills could be utilised in the workforce,
or how future content might be developed
to attract similar learners”
Willis, Quick & Hickey (2015)

THE MISSING LINK
#RIDE2016 | UNIVERSITY OF LONDON | 11-04-2016 | CC BY-SA | ILONA BUCHEM
“A missing link would possess the "in-between" evolutionary properties of both the
ancestors' original traits and the traits of the evolved descendants, hence showing
a clear connection between the two.” (Melina, 2010)

RESEARCH QUESTIONS
#RIDE2016 | UNIVERSITY OF LONDON | 11-04-2016 | CC BY-SA | ILONA BUCHEM
• Educational questions, e.g. How are OB transforming academic credentialing
and educational assessment? What is the impact of OB on motivation?
• Design questions, e.g. What designs appeal to targeted audiences? What is the
impact of OB on user engagement? How to create value proposition by design?
• Technical questions, e.g. How to embed trust mechanisms in the OB standard?
How to use Big Data to provide meaningful and useful metrics?
• Ethical questions, e.g. What are the risks of digital transparency and ethical
issues at the intersection of learning analytics and the data contained in OB?
• Community questions, e.g. How to grow global and local OB communities?
What approaches are effective in enhancing self-sustainable communities?
FUTURE RESEARCH
Design for learning with OB:
•For students, e.g. reflections on badges, learning pathways & playlists
•By students, e.g. peer feedback, e-portfolios, community learning
OB technologies for learning:
•Extending the Open Badge Standard (OB Extensions)
• Designing OB Backpack compatible systems and applications
Using OB to enhance the student experience:
•Learning experiences focused on and recognising passions & interests
• Making open learning/open education verifiable and credible with OB
