31. Context of the research
- Goal
- Defining understanding as a result of learning,
how do differences in user characteristics
contribute to differences in understanding
process models? -
4An example
5Kick-off
- Curtis et al. (1992)
- Goal
- facilitate human understanding and
communication - Sub-goal
- represent processes in forms understandable by
humans
6Gap-analysis
- Independent variables
- The effect of
- task complexity
- technology/process model characteristics
- on performance
7Visualisation
8Gap-analysis II
- Understandability defined as an intrinsic
property of a process model - Complexity, learnability, usability, etc.
- Pragmatic quality
9Why is this important?
- Practically
- ) helps representing processes in forms
understandable by humans - ) additional insights allow for more effective
training - Academically
- ) effects of users often averaged out by
assuming homogeneity (or x vs. y) - ) Maturity of the discipline will benefit from
an interdisciplinary approach
102. Theoretical background
- To learn is to be human
- (Goward)
11Theory of Cognitive Load
- Define information integration as a learning
process - Control factors of
- Content
-
- Content Presentation
12An example
13Learning Conceptualised
14Revisions
- Controlled Learning Context
- Limited Mutuality
15Controlling the Learning Context

20Input User Characteristics
- Identification of a framework which
conceptualises user characteristics in an
integrative manner - Problem-solving is inherent to human nature
- Usage of goal-setting behavioural theory
21Goal-setting Behavioural Theory

23During Learning
24Knowledge ConstructionGap analysis
- Static Approach hence limited availability
- Cardoso et al. (2006)
- short- and long-term memory
- chunking and tracing

39Configuration
- What to measure?
- How to measure?
- Who to sample?
40What to measure?
- Due to model complexity,
- test a part of the model
-
- a) Personal data prior to learning
-
- b) Information of their learning approach
during learning -
- c) Questions on understanding post learning
41a) Personal Data
- What to collect?
- Distal Variables Personality?
- Demographics?
- Culture?
-
- Skills Reading skills?
- Studying skills?
- Modelling skills?
42Examples of Frameworks
- Frederiks Weide (2006) Analysis Skills
- incl. Handle implicit knowledge, grammatical
analysis, abstract sentence structure, think on
an abstract level - Bandara et al. (2007) Content for IS Subjects
- From focus group analytical skills, understand
the problem, ability to communicate with client - Lindland et al. (1994) Quality
- Syntactic, Semantic Pragmatic Quality
- Vanderfeesten et al. (2007) Complexity metrics
- incl. Coupling, Cohesion, Modularity
43Skills

- e) Integration capacity
- f) Real time self-evaluation
- I) Develop effective strategies
- II) Problem-solving
- IV) Emotional stability
44b) Learning Approach
- Methods available
- Yet, is this useful?
45c) Understanding
- Methods available
- Only cognitive measurement?
- Indicators Recall Transfer
- Question answered correctly
- Problem solving
- Time?
-
- Incorporation of affective constructs
Cognitive Performance Behavioural Performance Affective Performance
46How to measure?
- Qualitative vs. Quantitative
Ability to measure all skills Control over context Scope No additional layer of interpretivism
47Fixed vs. Loose
- Should respondents be provided with a goal?
- Should meaningful learning be the outcome to aim
for?
48Tests, tests, tests
- some examples
- Spatial ability test
- Working memory
- integration test
- Reading ability
- Understanding of story
- Problem solving
- Cloze Recall test
- Cognitive Coupling
49Who to sample?
- Controlling the Learning Context
- vs.
- homogeneity of population
- Assume group differences (e.g. expert/novice)
- vs.
- differences by measurement
