2. How we encountered Threshold Concepts in
Plant Sciences
Enhance Student
Improve Learning Engage Students Recruitment and
Outcomes Better Retention

3. Research Approach
Identification
of desirable
practices
Analysis of Development
effectiveness of of resources
interventions
Implementation
of resources
and practices

4. Interviews with Tutors
• To identify successful tutorial activities for each
lecture topic
• To highlight areas where extra resources are
likely to be useful for students and tutors
• To get ideas for new types of resources

5. Mapping to Meyer & Land Definition

6. Threshold concepts identified
• Water potential
• Electrical potential
• Gene for gene hypothesis
• Circadian clock
• Species area curves
• Photoprotection
