Mixin Classes in Odoo 17 How to Extend Models Using Mixin Classes
Bochum augustus 2012
1. Supporting inquiry and modelling
with interactive drawings

2. Inquiry at school !?
Today at school the teacher had students start inquiry experiments. . .
They first submitted three questions they could study using plants. The
teacher then pointed them towards the ideas that were the most
workable. It was really cool to see some of the ideas they came up
with. Some students are feeding their plants Coke and others are
testing the difference between real and fluorescent light. They are also
using dyes and various types of soil — even gravel and sand. One
group is testing the effects of music on plants. I was really surprised
by the sophistication of their ideas— A lot of questions similar to the
ones in our methods class. There was even a plant hanging upside
down. It was very cool to see the inquiry method implemented.

6. What is wrong with
this?
Lack of theory Cookbook approach
“Experiments” are chosen Inquiry cycle as only
without any theoretical method of generating
motivation data
“The inquiry method” Disconnected from
real world science
Inquiry is seen as
something outside the
curriculum.
7. History of inquiry
research
Philosophy of Science Psychological
research
Popper
i. “Logic of discovery”
Simon, Langley,
ii. Falsification Qin
Kuhn, Lakatos, ... Inquiry is problem
solving
Paradigms, research
programs Generate, test and
revise.
Social aspects of
Inquiry Inquiry Cycle
10. What is the core of
inquiry?
And why do we teach it?
11. So, what about this?
Standard model
structured collection
of fermions and
bosons
Mathematical system
to explain interactions
and creation/
annihilation of
particles
12. Really generate-test-
revise?
Matter of scale?
Complexity?
Or fundamentally
different.
13. Standard model
Construct of
theoretical ideas
(fields, operators,
processes)
Internally consistency
as driving force
Symmetry
Covariance
Empirical validation
14. Model-based reasoning
(Nersessian, Giere)
Inquiry and discovery rely on the construction
of models
Visual and analogical modelling
Mental simulations
Requires creative and constructive activities
20. Mental simulation
Reason through the properties of the model
Using time, structures and properties
Realise implications and limitations of the
model
21. Inquiry and modeling
Inquiry is model-based
Experiments are not the only source of
evidence
Construction
Mental simulation
25. Supporting mental
simulation
Use animation and computer simulation as
augmentation for mental simulation
Providing support for “untraceable” situations.
31. SimSketch
Support for construction by drawing
No learning time
Intuitive specification of behaviour
Support for simulation
Animated behaviour of drawing elements
Multiplication, interaction, emergence
35. SimSketch development
and evaluation
Basic system
Trial in Masterclass
Empirical studies
36. Masterclass
(with Lars Bollen)
Six participants
Selected
From different schools
Goal: create a drawn model
37. Process
Pretest:
Purpose of models
Scientific Attitude
Introduction to Topic choice and Final model
modelling initial model
Exploring Adaptation to Posttest:
Purpose of models
SimSketch SimSketch Scientific Attitude
Evaluation of SimSketch
38. Purpose of modeling
Post:
Pre:
Simulations
Scale models
Improved view of
Fashion models
testing
Strive for
Focus on purpose
exactness
of model
39. Models!
Included six
Crowd management new behaviours
Predator prey system
Spreading of disease
Traffic (2x)
Influence of alcohol on brain
43. NEMO study
Annika Aukes
Science musuem
solar system, planetary movements, solar eclipse
248 participants, aged 7-18 (90% between 8 – 12)
pre-knowledge-test (domain: solar system)
SimSketch tutorial
modelling task solar system
modelling task solar eclipse
Post-knowledge-test (and others)
44. Results
younger children (<= 11) have higher
learning gain than older children
but: ceiling effect
model score does weakly but significantly relate to
learning gain
positive correlation between age and
perceived easyness
negative correlation between age and
perceived value of SimSketch
but remarks that it is nice for younger children
45. Retrograde motion study
Hanna Schmalz
Specific study into modeling retrograde
movement
31 students (11-12)
Tasks: draw the solar system as you know it.
Try to explain the retrograde motion of
Venus using your drawing and simulation
Measures: knowledge, science attitude
46. Results
General increase in attitude towards science
More with boys than girls
General increase in knowledge about
planetary motion
More with girls than boys
Much better expression of retrograde motion
in drawings than in words.
47. Summarizing
Inquiry is a model building activity
Construction and Mental simulation as core activities
SimSketch
Drawing to support construction
Animation to support mental simulation
Way to go:
range of models
assessment of learning
user interfaces for exploring building and exploring models
