Innovedum Project
28.02.2018 Melanie M. Erzinger 3
We want to achieve…
1) …a better instruction of the basics (security, handling, reports)
2) …widen the experience with important experiments that cannot be conducted physically in the lab with all students (Kjeldahl, LC/MS)
3) …collaboration (and critical thinking) among students
4) …a stronger attractiveness for the students
Intervention
TORQUE format
interactive videos
virtual labs
instant lab reports
peer-review process
Ø interactive, social, virtual & 3D

good, innovative idea how to solve the problem
(deadline: March/October 1st)
Let’s go!
Ø get help from educational developers
Ø have alternatives in mind

Challenges in the lab course…
28.02.2018 Melanie M. Erzinger 12
§ 20-30 students § tight supervision § more time for individual
questions
10 years ago today
§ 60-80 students § supervision difficult § challenging experiments
problematic (safety issues) § less time for individual
questions
Ø majority of the students does not prepare in advance (many do not even read the protocol)
Ø a lot of time gets lost with repeating basic things again and again

§ professional videos § good sound § possible to have multiple languages § professional support during whole process § positive effect observable after the first year
TORQUE videos – practical information
28.02.2018 Melanie M. Erzinger 17
§ expensive (30’000 CHF total for 9 videos) § process rather long (planning, skript etc.) § cannot be changed easily afterwards

§ fully interactive advanced lab simulations § for experiments that cannot be conducted in the lab (safety,
infrastructure, money, time…) § Kjeldahl, LC-MS analysis
2D Simulations
28.02.2018 Melanie M. Erzinger 18
in collaboration with Labster
• professional simulations • rather low own effort • unlimited access for our students
• high costs • final product, nothing can be
changed anymore
