Pia Jensen

Moderator, content manager

• Connects theory and experiment

• MC raytracing simulations

• Design and Optimization of instrument

• Overview and details of instrument components

• Training of users

• Planning of experiments

• Seperation of scattering contributions

(background from Sample Env., Incoh. scatt. etc)

• Data analysis

(resolution, peak broadening, spurions, multiple scattering)

Teacher

Student

• Online encyclopedia
• Searchable
• Never outdated
• Contributions from experts
• Homogeneous
• but need for moderation of e.g. notation

• Text material
• Exercises
• Hints
• Solutions
• Based on notes by K. Lefmann and H. Schober

Applets

Pilot project

Specifications

• Monte-Carlo neutron raytracing (McStas)
• Illustration of complex user-defined problems
• Interactive
• Familiarises the student with particular instruments
• Virtual experiments

• Simple illustrations of a basic principle
• Usually non-interactive
• Visualisation of physics and math
• Faster understanding

Live-SIM

LESSONS

NMI3 E-learning project (4 years)

• University students
• Their teachers/supervisors
• Scientist from other fields

Instruments

Internet distributed material

• University of Copenhagen 'Neutron scattering in Theory, Simulation and Experiment',
• ~20 students, 8 weeks + 1 week @ PSI
• Collaboration with Department f. Science Education (J. Bruun)
• Collaboration with Faculty of Life Sciences (L. Arleth, K. Mortensen, S. Kynde)

• VNT is hosted at TUM
• LAMP server 24 cores (for live-simulation)
• McStas, MediaWiki, Moodle
• Varius plugins/ extensions/ tools for math and physics
• test server
• running server

• Template instrument suite representing all major neutron techniques
• Essential parameters like bandwidth and collimation can be changed by the student

https://portal.esss.dk/livesim/sim.php

• Internet as an open database supplement to teaching
• Material is selected by student i.e. not directed by teacher
• Typically information in uploaded documents ( eg PDF's from neutron schools ) printed out and used in class-room

Quizzes

Samples

• Questions
• Answers
• Feedback
• Grading
• Could also be based on live-sim

Internet based lessons

• Template sample suite
• Look at data from different samples at same instrument setting
• Data treatment like real experiment, e.g. powder refinement by FullProf
• Instr+sample = Virtual experiments

Evaluation

• Webpage is the starting point of teaching (the virtual class-room)
• Use structure and possibilities of internet (animations, videos etc)
• Material is selected by teacher
• Student works interactively with material

Proposals

E. Farhi, ILL

• Virtual experiments
• For a given scientific problem which instrument(s) would you choose?
• Resolution, range, time
• Background from e.g.SE

• Web Analytics to collect user behaviour information
• Statistical analysis - didactical interpretation
• Feedback forms
• Discussion pages

• TUM 32 person-months
• UCPH 30 person-months
• ILL 16 person-months
• DTU 3 person-months

Feedback

• Correction of WIKI/Lesson text (typo's etc)
• Extension of existing text
• New text material
• Level of hints
• Details of solutions
• New exercises
