Challenges lab classes
● Lab space
● Differences in starting level
● Staff availability
Goals
● Stimulate self-activity
● Learning outcomes
● Reduce time to explain basics
Innovation of lab classes Food Microbiology
Food Microbiology (BSc-2)
● 3 weeks -> 2 weeks of lab classes
● Digital assignments
● Lab clips

# s
tudents
Food Microbiology, in silico experiments
Each assignment: 2-4 h
● Microscopic ID of fungi
● Variability in results (statistical data analysis)
● Thermal resistance
● Molecular ID of bacteria
● Disinfectants

Innovation of lab classes Advanced FM
Advanced Food Microbiology (MSc-1)
● Design preservation experiment
● Different starting level students
● Design day 1, start experiment day 2
● Not enough time for feedback, preparations
● Labbuddy
● Design tool (ExperD)
● Web lab manual

Web manual
Protocols
● Prepare mode
● Work mode
● QR code, easy access with tablet or smartphone
Including lab clips

Adv Food Microbiology, design tool: ExperD
Design preservation of raw food
● Choose food, treatment, storage temp, mo, ....

ExperD:
● Brush up knowledge, Q & A, feedback
● Explanation experiment and tool
● Design page, drag and drop
● Choices and feedback
● Link with web lab manual
● List items needed
● Start experiment

1.1 ExperD guided me through the design smoothly.1.2 ExperD enabled me to set priorities for this experiment.1.3 ExperD supported efficient to design of my experiment.2 ExperD stimulated collaboration within our group.3 I found the information and feedback in ExperD helpful.4 While using ExperD, we could work more independently than without.5 ExperD should be applied in other experiments as well.6.1 The difference between the prepare mode and work mode was clear.6.2 Prepare mode and work mode helped me to understand the experiments better.6.3 Prepare mode and work mode made the experiments easier to perform.7 While using WebLM I often had to ask the supervisor for help.8 I prefer a paper copy of the protocols above a digital version. 9 I did use the option to watch protocols on the phone or tablet in the lab.10 WebLM should be applied to the other protocols (e.g. pathogens) as well.

Summary result of innovations
28
● Able to cope with larger student groups
● Lab classes two weeks instead of three
● Two consecutive groups, planning easier
● Less lab space needed, less apparatus, less staff
Summary result of innovations
30
● Able to cope with larger student groups
● Lab classes two weeks instead of three
● Two consecutive groups, planning easier
● Less lab space needed, less apparatus, less staff
● Fewer low cognitive questions
● Digital assignments highly appreciated
● Stimulates collaboration within groups
● Approval to order media automatically
● Media easily ordered and distributed
● Use in other courses as well
