IoT and Practical Laboratories

2. IoT and practical laboratories:
The 6 Ws

3. WHY?
Context
3

4. Lack of professionals in Cloud Computing
• 1.7 million cloud computing jobs unoccupied
• Estimation of 7 million cloud-related vacancies worldwide (IDC)

5. Internet of Things (IoT)
• European Committee estimated that the market value of the IoT in
the EU exceeded one trillion euros in 2020
• 2014: 300,000 developers / 2020: 4.5 million
– 57% compound annual growth rate and a massive market opportunity

6. Internet of Energy (IoE)
• Particular case of IoT: Energy-oriented
– Integration of energy systems, communication and electronic systems
and web services
• IoT-based smart sensors to assess performance and provide real-
time analytics
• Problems:
– lack of professionals in the sector
– low level of knowledge of the technology

7. 7

9. SME situation in EU
IoT can apply to almost all of these sectors!

10. WHAT?
Introduction to practical laboratories

11. 11
Practical skills acquisition is key in engineering education…

12. 12
…but… how to teach the practical competences on-line?

13. Ø Virtual labs
Ø Remote labs
Types of demonstrators
Web-based but connected to
real equipment
Purely software simulation,
web-based

14. Ø Didactic resources available on-line
Ø Allows interacting with real environments through the Internet
§ Where “real” may mean: a hardware device, a platform for IoE, the use
of IoE protocols, IoE mobile apps, etc

18. WHERE?
Remote Laboratory Management Systems
18

19. • Lab2go: a Web environment where people can share expertise and
experience in the field
• LiLa (Library of Labs): a European eContentPlus project
• iLab: an architecture that supports a fast platform-independent lab
development
• WebLab Deusto. It provides APIs and different approaches to
include new or existing remote labs
• CORE SCORM: Adds to SCORM a Web Service Runtime
Communication Profile Standard
• LTI (IMS Learning Tools Interoperability)
• IEEE Std 1876 – 2019: IEEE Standard for Networked Smart
Learning Objects for Online Laboratories
• OCELOT (Open and Collaborative Environment for the Leverage of
Online insTrumentation) is an open source and collaborative Online
Laboratory framework and middleware
• LMSs
Analyzed RLMS for IoT practical laboratories
19

20. • These traditional RLMSs (WebLab Deusto, iLab, LabShare,
Lab2Go, LiLa, …) do not work for this project
• IoTecosystems are complex
• Our laboratories may be made of a Website but also may include…
– a desktop application
– a virtual machine
– the use of a commercial website
– a simulator
– a console-only program
– a mobile app
– ….
• However, RLMS only focus on web-based labs
How to manage an heterogeneus set of virtual and
remote labs for IoT?
20

21. • Open-source platform will be considered preliminary
– free and easy-to-maintain platforms
• Reusability and standardization
– Possibility of easy integration within the project web-platform and, if
possible, any other external platforms.
– Thus, the use of educational interoperability standards such as SCORM
may play an important role.
• Open licence
– The developed contents within the project must be published under
open licence
Repository requirements
21

22. And the winner is… Vish
Ø Open repository for OERs
§ Everything published there is under an open licence (CC, …)
§ Allows searches and reusability of resouces having into account
language, difficulty, topic, ….
§ SCORM and LOM complaince
§ Also embedding through iframe
Ø HTML5 interactive on-line presentations
§ Allows aggregate third-party external on-line resource inside a slide
§ On-line Authoring tool
ü kind of MS Powerpoint
§ Video embedding
Ø Social network

54. Ø According to the work done in the "Global Online Science
Labs for Inquiry Learning a School" (Go-Lab) project, the main
stages involved in an inquiry learning process using virtual
and remote labs may be divided in 4 stages:
Inquiry learning Methodology
Contextualization
• Provide instructions
of the context of the
demonstrator.
Orientation
• Provide clear
instructions of what
the student must do
to use the
demonstrator.
Experimentation
• Use of the virtual/
remote lab according
to the instructions
provided. It may
include the
embedding of an
iframe with the lab.
Conclusions
• Description of the
key findings that the
student should have
obtained in the
experimentation
stage. It may include
some kind of auto
evaluation test.
