Project
Distributed Development of a Virtual Science
Museum with Guide Applied to Education in
Acoustics

Science museum

• Create ICT course material

• small learning objects, different levels

• ?

• What about effectiveness of material in improving
  students insight?
• What about student appreciation?
• How do they use the material?

• Student project to evaluate

8
Evaluation

• Design project

• design Helmholtz resonator
• students are familiar with basic acoustics
• information needed to solve the problem on the
  internet

• first IT in education-experience for students

9
Evaluation

• Design project

Why?

• different solution paths

Evaluation

• Design project

Why?

• collaboration
• free exploration of material and use new insights
  in practical application

• different solution paths

15
Evaluation

• Design project

• Oral exam
• to defend project
• to test insight in operation of Helmholtz
  resonator

16
Evaluation

• Survey
• How did they cope with the project?
• What material did they use?
• How do they perceive their gained insight?
• How is their overall appreciation with IT in
  education?

• Design project
• Oral exam

17

Results - project

• Legend
• HR perception insight in operation Helmholtz
  resonator
• AI perception insight in acoustic impedance
• SP perception insight in sound propagation in
  ducts
• score score on oral exam question related to
  project
• not significant

23
Results - project

• Analysis
• focus on applet ? only insight in problem at hand

24
Results - project

• SP only was mentioned in pages concerning limits
  of the theory

• Analysis
• focus on applet ? only insight in problem at hand
• focus on equations and derivation ? theoretical
  insight

• Analysis
• focus on applet ? only insight in problem at hand
• focus on equations and derivation ? theoretical
  insight
• strong neg. corr. not reflected in students
  result, perhaps only these students realise the
  complexity of the matter

25
Results - project

• neg. corr. year score perception insight
• better students unsatisfied
• better students dont easily state to understand
  something completely
• they perform well in current system and dont put
  much effort in an alternative project

Analysis
26
Results - IT in education

• negative correlation wish more ICT - performance
  current system

Analysis
27
Results - IT in education

• students like self-assessment tools
• possibilities of hypertext to hide unessential
  information, cross-link different topics not
  estimated very high

• Analysis
• applets to explore influence of parameters are
  highly appreciated

28
Results - IT in education

• more students afraid to waste time
• it is more clear what has to be learned
• less students fear theyll have to work more

• Analysis
• in course context

29
Conclusions

• Students appreciated exploration and design
  problem
• majority students have the impression they have
  gained insight
• exploration stopped at earlier stage than hoped
  for (study culture?)
• Unexpected negative correlation performance
  students in current system - appreciation of
  project / IT
• tuning seems appropriate
• appreciation may depend on context in which IT is
  used
• Structure!
