12. What do we know about the development of
systems thinking and its assessment?
- Studies from expert’s point of view
- Lineal path based on Bloom: Hooper and Stave (2008)
- Studies from learner’s point of view (qualitative)
- Frank, 2000
- 30 Laws for Capacity for Engineering systems thinking
- Richmond, 2001
- A subset of 7 critical thinking skills
- Davidz, 2006
- experiential learning, individual characteristics and
supportive environments key to develop systems thinking

13. Variation theory of learning
learning is about an increase of the amount of
critical aspects and features the learner can
discern and be focused on simultaneously
[from a dimension or conception]. (Marton,
2014, p. 60
Learning can be seen as moving from one
way of seeing and dealing with the
problem to another more powerful
(Marton, 2014)

Data Analysis
Marton’s approach
- Look for different ways to address the problem
- Have them in one place
- Rip them off their context and the participant
- Define different categories
- Define a hierarchy
- Simple to powerful
