Title: BPM Seminar understandability of process models


1
BPM Seminarunderstandability of process models
  • A users perspective on learning

2
Topics
  1. Context of the research
  2. Theoretical Background
  3. Theoretical Design Conceptualisation
  4. Measurement
  5. Questions?

3
1. 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?

4
An example
5
Kick-off
  • Curtis et al. (1992)
  • Goal
  • facilitate human understanding and
    communication
  • Sub-goal
  • represent processes in forms understandable by
    humans

6
Gap-analysis
  • Independent variables
  • The effect of
  • task complexity
  • technology/process model characteristics
  • on performance

7
Visualisation
8
Gap-analysis II
  • Understandability defined as an intrinsic
    property of a process model
  • Complexity, learnability, usability, etc.
  • Pragmatic quality

9
Why 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

10
2. Theoretical background
  • To learn is to be human
  • (Goward)

11
Theory of Cognitive Load
  • Define information integration as a learning
    process
  • Control factors of
  • Content
  • Content Presentation

Learning Conceptualised

Revisions
  • Controlled Learning Context
  • Limited Mutuality

15
Controlling the Learning Context
  • HOW?

3. Theoretical Design Conceptualisation
a Cognitive Perspective onLearning
17
Structure
  • Gap Analysis
  • Introduction of a framework
  • Integration into learning theory

Input 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

Goal-setting Behavioural Theory

Eight Variables

During Learning
24
Knowledge ConstructionGap analysis
  • Static Approach hence limited availability
  • Cardoso et al. (2006)
  • short- and long-term memory
  • chunking and tracing
  • Hungerford et al. (2004)
  • Task Planning
  • Others, e.g. Central vs. Peripheral, Queues

25
Throughput Knowledge Construction
  • Identification of a framework that describes
    Knowledge Creation
  • Mandviwalla Hovav (1995)
  • Motivational process

Learning OutcomeGap analysis
Cognitive Performance Behavioural Performance Affective Performance
Agarwal Karahanna, 2000 Behavioural Intention to Use
Aranda et al., 2007 Correctness of understanding Time to completion Confidence Perceived Difficulty
Goodhue et al., 2000 Time to completion User Evaluation of consistency User Evaluation of training
Igbaria et al., 1997 System Usage
Mendling et al., 2007 Number of questions correct Perceived understandability
Recker Dreiling, 2007 Number of questions correct Cloze Recall test Problem Solving task Time to task completion Ease of Understanding
Venkatesh Bala, 2008 Use Behaviour

Output Learning Outcome
  • Identification of a framework which
    distinguishes between different types of
    understanding

4. Measurement
39
Configuration
  • What to measure?
  • How to measure?
  • Who to sample?

40
What 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

41
a) Personal Data
  • What to collect?
  • Distal Variables Personality?
  • Demographics?
  • Culture?
  • Skills Reading skills?
  • Studying skills?
  • Modelling skills?

42
Examples 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

43
Skills
  • Syntactic Skills a) Word comprehension
  • b) Vocabulary syntax
  • II) Identify obstacles
  • Semantic Skills c) Spatial ability
  • c) BMP modelling discourse
  • d) experience/past behavioural skills
  • I) studying habits
  • II) identify obstacles
  • Pragmatic Skills e) Working memory
  • e) Integration capacity
  • f) Real time self-evaluation
  • I) Develop effective strategies
  • II) Problem-solving
  • IV) Emotional stability

44
b) Learning Approach
  • Methods available
  • Yet, is this useful?

45
c) 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
46
How to measure?
  • Qualitative vs. Quantitative

Ability to measure all skills Control over context Scope No additional layer of interpretivism

47
Fixed vs. Loose
  • Should respondents be provided with a goal?
  • Should meaningful learning be the outcome to aim
    for?

48
Tests, tests, tests
  • some examples
  • Spatial ability test
  • Working memory
  • integration test
  • Reading ability
  • Understanding of story
  • Problem solving
  • Cloze Recall test
  • Cognitive Coupling

49
Who to sample?
  • Controlling the Learning Context
  • vs.
  • homogeneity of population
  • Assume group differences (e.g. expert/novice)
  • vs.
  • differences by measurement
