Core Questions

What is the Internet of Things? How to teach it? How to ensure long-lasting skills?

Why is it different?

Deep scientific knowledge against wide- spread application skills Very short living technologies and trends No new science, a combination of:

Systems (hardware) Software engineering AI and data science Security Human-computer interaction

Impossible to teach them all – how to manage the balance?

Idea:

  • Sensor nodes, which

are contacted over a Access Point.

  • Protocol Type is a

UDP/IPv4-Protocol.

  • If a sensor is not

connected to the AP the LED shows an error Idea:

Some advise for teachers …

Large one-time preparation effort, small recurring effort Design labs independently to easily exchange later Interactive sessions and labs are more effective than lectures!

Take away

Flexible study programs with focus on hands-on experience Rather broad skill and knowledge spread Teach how to learn alone and where to find expertise and new knowledge Life-long learning
