7. How do we evaluate open digital
resources?
What do we mean by ‘open’? Free?
Accessible? Flexible?
Is being ‘open’ enough? Don’t
forget the ‘education’ part
‘Open’ is an emotionally charged
word
Need for criteria that are VALID
and RELIABLE

9. Models of innovative open education
Four models:
• MOOCs: Coursera (Duke University)
• Open educational resources: MERLOT
• Open university: UK
• Online credit program: UBC, Canada
‘quality assessment’ using the A C T I O N S
model
9
10. Model 1: MOOC
Duke University (Coursera):
bioelectricity
• open access (no formal qualifications)
• fully online (lecture capture, CMAs)
• free
• top private research university in the
USA
• statement of accomplishment
10
11. Model 2: OER
MERLOT: collection of peer-reviewed
OERs
• Roman architecture, Yale
• open access
• fully online (multi-media)
• free
• ‘open’ use
11
12. Model 3: Open university
Open University, UK: B.Sc. (Hons.) Science
• Open access (no formal qualifications)
• Multimedia materials, tutors and online
forums
• Cost: 17,000 euros = 5,700 per year;
(international students pay more)
• Top 20% in research and teaching in UK
12
13. Model 4: Online credit program
UBC online credit program: Master in
Educational Technology (fully online)
• Single courses/certificate: open access
• Masters: graduate entry qualifications
(bachelor’s degree)
• From anywhere in world
• Cost: 11,000 euros =5,500 per year or 1,100
per course
• Tier 1 research university

22. Conclusions
• ‘open’ is a multi-faceted concept
• access alone is not enough; quality
matters
• need a clear set of criteria;
alternative models possible
• more innovation needed; and
possible
• But: well-funded public education
system best guarantee of open access

23. Questions
Evaluating the quality of open digital resources
1. Are these the right criteria? If not, what other criteria should
be considered?
2. Do the numerical values make sense?
3. Is there a better/more ‘scientific’ way to evaluate quality?
