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
Bloom’s taxonomy
Categories in the cognitive domain of Bloom's Taxonomy (Anderson & Krathwohl, 2001)

• Group participation (5 groups)
• Referencing sources (websites, books, and journals)

• Students were engaged in graded tasks• Increased percentage of postings for three cases:
S1 (31 percent)S2 (32 percent) S3 (37 percent)
• Improved quality of discussion gradually emerges An increase in the number of postings in
‘apply and analyse’ in S2 and S3 A decrease in the number of postings in ‘remember’ in S2 and S3
