23 May 2000MicroQuim 20002 Four points of view Industry and government (I) Teachers in secondary education (T) University (U) Pupils (P)
3
23 May 2000MicroQuim 20003 Where are the Netherlands?
4
23 May 2000MicroQuim 20004 What are the Netherlands? A small country between England (overseas), Germany and Belgium 9220 km (5730 miles) from Mexico City 15,750,000 people World’s largest port: Rotterdam Home of Shell, Akzo-Nobel, Unilever, DSM
5
23 May 2000MicroQuim 20005 What is produced in the Netherlands? Windmills (a few) Wooden shoes (some more) Flowers (lots) Peanut butter (World’s #2) Chemicals (tons)
6
23 May 2000MicroQuim 20006 Chemical industry (I) Largest branch of industry 60% bulk / 40% fine 15% of industrial production 20% of industrial export 10% of employment
7
23 May 2000MicroQuim 20007 Chemical industry (I) Twice as much academics as in other branches Achilles heel: number of chemists educated
8
23 May 2000MicroQuim 20008 Interest in chemistry Final exams 1999 (I)
9
23 May 2000MicroQuim 20009 Interest in chemistry Final exams 1999 (I)
10
23 May 2000MicroQuim 200010 Interest in chemistry First-year students in 1999 (I) University537 (≈2%) Higher Laboratory Education472 Higher Vocational Education214
11
23 May 2000MicroQuim 200011 Consequences for secondary chemistry education (I) Chemical industry and government are willing to spend money! Schools adopted by companies Projects are initiated and supported AXIS-project to promote science and technology
12
23 May 2000MicroQuim 200012 Change of doctrine in upper- secondary education (T) ‘Studiehuis’ ≈ study-home independent learning streams projects introduced summer 1998 and 1999
13
23 May 2000MicroQuim 200013 Consequences for secondary chemical education (T) Need for a real-life approach Need for example projects Need for a student oriented lab
14
23 May 2000MicroQuim 200014 Late eighties (U) Universiteit van Amsterdam: Desire for a microscale laboratory in second year Mayo, Pike & Trumper Microscale Organic Laboratory very interesting too expensive
15
23 May 2000MicroQuim 200015 Method and kit (U) Williamson ‘Macroscale and microscale organic experiments’ economical
16
23 May 2000MicroQuim 200016 Introduction into the curriculum (U) Williamson visited Europe instruction for PhD students summer 1989 half of the second year organic lab miniaturised winter 1990 conversion complete
17
23 May 2000MicroQuim 200017 Results (U) Reduction of waste chemicals cost of breakage to 15%
18
23 May 2000MicroQuim 200018 Further steps (U) summer 1997 second year inorganic lab miniaturised Szafran, Pike, and Singh ‘Microscale inorganic chemistry’
19
23 May 2000MicroQuim 200019 Consequences for secondary chemical education (U) Lecturer was member section chemical education of the Royal Netherlands Chemical Society promoted microscale chemistry initiated a project
20
23 May 2000MicroQuim 200020 Project Microscale experiments Universiteit van Amsterdam & Chemistry Communication Center Foundation November 1996 - December 1999 glassware low-cost heating device manuals training
21
23 May 2000MicroQuim 200021 Glassware
22
23 May 2000MicroQuim 200022 Low-cost heating device
23
23 May 2000MicroQuim 200023 Manuals Adaptation of existing experiments Teachers manual and students manual are loose-leaf: flexible rearrangeable supplements
24
23 May 2000MicroQuim 200024 Training Over 330 schools (> 50%) 600 teachers One afternoon training on-site at the University
25
23 May 2000MicroQuim 200025 Future plans more experiments projects including a teacher-training coupling with computer (Coach 5) PhD-research project: another road to organic chemistry Axis-project: Industry on microscale
26
23 May 2000MicroQuim 200026 Industry on microscale 3-year project teachers and industrial chemists work together to make: teaching materials related to real contexts blueprint for school-company co-operation
27
23 May 2000MicroQuim 200027 Other microscale initiatives (U&I) Vrije Universiteit Amsterdam & Chemistry Communication Center Foundation Chemistry in droplets
28
23 May 2000MicroQuim 200028 Other microscale initiatives (T) Frans Killian (teaching assistant) & Aonne Kerkstra (teacher): Miniaturisation of their own school laboratory 96-well microplates micro titrations µ-GLC
29
23 May 2000MicroQuim 200029 (P) Why microscale experiments? Michael Schallies (Heidelberg, Germany): “We must focus on the 95% pupils that do not choose to become a chemist” “Their chemistry in school is the only change in their lives to explore nature by experimenting”
