Measuring from a societal problem
• Science:
– Envirement: pollution, flooding, …
– Gaining and try to understand scientific phenomena
– Draw conclusions, seek for evidence (come to
definitions)
– …
Measuring within
technical application areas
Transport, Energy, Biochemics, ICT, Construction
• Technique:
– Signaling (alarm)
– Level measurement of liquids
– Distance measurement
– Automatic steering by measurements (pump operating
system)
– Conductivity
– Fault tracing
–…

Can someone
close that
water tap !!
Other solutions ???
Measuring by educational level
Primary education (-12 y)
• Subject material: simple electrical circuits
– Measering the electrical circuit
– Conductor and isolator: solid materials
• Realisation:
– Measuring instrument: simple electric circuit
Measuring by educational level
Secundary education (12 -14 y)
• Subject material: electrical circuits
– Extending of the electrical circuits, also with electronic
components
– Measurement exercises - fault finding methode
– Conductor - isolator solid materials
– Conductor - isolator liquids
• Extending material:
– Measurement: water level meter
– Steering: with measuring instruments
– …
Measuring by educational level
Secundary education (12 -14 y)
• Surching for solutions
Measuring by educational level
University college BASE Technique
• PE + SE preparations practical - teaching strategy - didactic
approach
– Subject material: electrical circuits
• PE: electric circuits with the basic elements
• SE: electric circuits with electronic components
– Subject material: components measuring instruments
• PE: from a simple continuity tester (LED, connector
block, source, conductors, banana plugs) (simplest
version of the measuring instrument)
• SE: sensitive measuring instrument (jumboled, different
values resistors, to calculate the resistor, transistors,
source, banana plugs - measuring leads)
Measuring by educational level
University college BASE Technique
– Subject material - method of how to measure, fault
finding
• PE: simple measuring instrument
• SE: sensitive measuring instrument
– Skills:
• PE: Connecting conductors, cut - dismantle
conductors, polarity LED - battery clip, connecting
battery clip 2x1, 5V, ...
• SE: Connecting conductors, cut - dismantle
conductors, polarity LED - battery clip, calculating
resistors - connecting resistors, drilling plastic, …
Measuring by educational level
University college BASE Technique
– Developing didactic boards, teaching materials
– Creating material to realize the steering exercises in SE
• Steering pump installation by flooding
• Activation of alarm
systems
•…
Interpretation of
Technology and Sciences in Flanders PE
Recent proposal by the Minister of Education in Fl:
• Science and Technology should be more included in the
curriculum in PE
• WHO ?
– Todays teacher PE in FL: Do they have the know how?
The knowledge, skills and teaching methodology ?
– A specialist teacher Science and Technology in PE ?
• WHAT ?
– What subject material, Knowledge, skills, ... ?
• HOW ?
– …
Interpretation of
Technology and Sciences in Flanders PE
Recent proposal
S & T should be more included in the curriculum in PE
• HOW ?
– Teaching methodology !?
• Scientific thinking and Technological thinking ?
– separately or a combination between the two ?
– Indicate the connection between the two ?
• Science and technology are connected to each other ?
• A view from both approaches, but retain the difference ?
Interpretation of
Technology and Sciences in Flanders PE
• HOW ?
– Teaching methodology !?
• Scientific thinking and Technological thinking ?
– separately or a combination between the two
– Indicate the connection between the two
• Science and technology are connected to each other ?
• A view from both approaches, but retain the difference ?
Therefore, our learning track for both PE and SE:
Your opinion ? What are your experiences, views, reviews ?
Something for a discussion?
Interpretation of Technology
Something for a discussion?
• Our ‘vision’ – But is this a good vision that you can defend?
– The specialist provides basic knowledge on to the pupils?
You can only be a specialist if you get directly taught the
correct instructions (worker - performer)
– The pupil knows the basic and should look to expand,
depending on the problem (thinker)
– Inventor: The thinking, but few perform. The execution is
done by others (fantasist)
• These three approaches or platforms each have their
individual character and should not be part of comparing.
There may be an interaction, but it is no must.
Each pupil should feel good in a determined situation.
