OLnet is searching out the
evidence for effec4ve OER, and building an Evidence Hub — a living map by, of and for
the OER movement — and those we need
to impact

Phenomena of interest analytics on qualitative aspects of discourse
• What is the impact/significance of this resource, or concept?
• Who is tackling this challenge?
• What claims are being made?
• What is the evidence to support this view?
• Who is building on whose work?
...analytics such as these are central to knowledge-building, but cannot be derived from unstructured discourse platforms
(cf. CSCL/CSCA research esp. CSILE/KnowledgeForum: Scardamalia & Bereiter)

• More active platform (eg. recommender)
• Automated rhetorical text analysis
• Rollout and evaluation of Open Edu Evidence Hub
