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

§  replace a lecture about the topic

§  can be watched multiple times by the students

Videos «Report Writing 1-3»

challenging situation

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

Videos and Simulations

28.02.2018 Melanie M. Erzinger 13

Self-made videos TORQUEs 2D

simulations

Virtual Reality (3D)

AugmentedReality

Self-made videos, portable video station

28.02.2018 Melanie M. Erzinger 14

•  cheap •  easy •  flexible use

•  not professional •  quite room needed

for recordings •  effort (everything

self-made)

| |

TORQUE videos (supported by Emil Halter Foundation)

28.02.2018 Melanie M. Erzinger 15

TORQUE videos – practical information

28.02.2018 Melanie M. Erzinger 16

in collaboration with ID MMS

Video studio Tablet/Smartboard

On site/in the lab §  October 2016 – January 2017 §  actual filming in the lab: 1 week §  studio smartboard: 1 day §  audio studio: 2 days §  assistant for 3 months (30%)

| |

§  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
