Background
Year 3 students of a four-year Bachelor of Science (Nursing) programme
Class of 124 students
Five groups were randomly formed
3 cases were reconstructed from real cases and each case was split into 3 parts.
Case analysis: Face-to-face tutorials & online tasks ( 5% ):
Based on each case, students posted topics, issues and hypotheses, peer group members were to post subsequent threaded discussions.

Blended PBL

“ Remember” were significantly different between cases, c2 (2, N = 559) = 28.0, p < .001
Similar findings were seen in the postings categorized as “Analyse/Apply” with c2 (2, N = 559) = 8.66, p < .013

Mapping top / low 10% students in examination with uses of referencing materials in online forum
