The document discusses the design of Rebo, a reflection guidance chatbot for apprentices in mechatronics, metal, and electrical engineering. Researchers aim to understand apprentices' computer usage, identities, and communities of practice. They also seek to design an effective dialogue structure for Rebo Junior to lead reflective conversations and evaluate how adaptations improve reflection guidance. Initial results found apprentices enjoyed interacting with Rebo Junior and their conversations were coherent and reflective. Repeated interactions were also found to improve apprentices' reflection skills.

DESIGNING REBO CHATBOT FOR APPRENTICE REFLECTION
1. DESIGNING REBO, THE REFLECTION
GUIDANCE CHATBOT
Styrian SME’s need an online learning platform for their
apprentices in mechatronics, metal and electrical engineering.
Research opportunities:
• Apprentices as target group are under-researched
• Designing a computer-mediated learning intervention in the
overlap between workplace learning and educational setting
• Contributing to research on reflection guidance technologies
• Developing the first reflection guidance chatbot
1. Understanding the target group
RQ1: How do apprentices use computers and how self-
efficacious are they with regard to ICT?
RQ2: What characterises apprentices as a community of
practice with special regard to their learner identities?
2. Designing the learning intervention with guided
reflection & continuous evaluation
RQ3: How apt is the dialogue structure Rebo Junior to lead
successful reflective conversations with apprentices?
RQ4: Which adaption mechanisms improve reflection
guided by a conversational agent?
RQ5: Do apprentices’ reflection skills improve with
repeated interactions with Rebo?
RQ3 (Wolfbauer et al. 2020)1
1. Apprentices (n=18) like texting with Rebo Junior!
• Workshop feedback: 94% like Rebo, 70% see benefit
2. Interactions with Rebo Junior (153) are coherent and reflective
• 97% coherent conversations
• 75% reached reflection stage 2: analysis2
• 87% reached reflection stage 3: learning & change2
RQ1 (Paper in peer-review)
• Apprentices use computers regularly, for multiple hours per day
• Computer self-efficacy of apprentices is high
• Apprentices’ potential to work digitally is underused in
apprenticeship training

Hello Rory!
Hello
What task are we talking about
today?
My fourth cnc turned part
What did you do for this task? Tell me
step by step.
I wrote a program according to the
sketch
Are you happy with the result of your
work? Why/Why not?
I’m not sure, there are some problems
with the implementation because new
task elements were added
How did you feel while working on
this task?
As if my head was about to explode
What was the problem?
The problem is […] and this is
confusing for me
Oh no! I hope you’ll have more fun
next time!
What did you learn from this task?
How to write a program
Can you describe this a bit more?
I learned how to write a program and
enter it into the cnc lathe
When could you need what you learned
here again?
At cnc la
In order to understand what you mean,
I’m going to need a bit more text ;)
I mean that I will apply what I have
learned when I’m back at my company
Sounds like a plan!
No Problem
Awesome, thanks for the talk!
I think this talk was really cool, I’m glad
that you do your best :D
Take care :-)
Bye

Assessment
RQ5 (Paper in peer-review)
• Coding 4 reflection levels: Judgement, Emotions, Learning,
Planning: (0/1/2 for each level → total scores: 0-8)
• Significant improvement of apprentices’ reflection competence
1. Apprentices’ Computer Usage and ICT Self-Efficacy
• Questionnaire study with 72 apprentices
• Complemented with 6 in-depth interviews
2. Apprentices’ Learner Identities and Community of Practice
Semi structured in-depth interviews:
• 8 apprentices, 3 supervisors, 3 trainers
• Data available, analysis upcoming
3. Learning platform for apprentices → Contextual Design
4. Designing a dialogue structure that leads apprentices through
successive levels of reflection: Rebo Junior
• Experimental field studies (2x 3 months)
• Evaluation: user acceptance, reflectivity & coherence of
interactions
5. Designing Rebo, the Reflection Guidance Chatbot
• Experimental field studies (2x 1 month, 1x 3 months)
6. Measuring apprentices’ reflection competence & SRL skills
• Pre- and post-tests: reflective essays
• Pre- and post- surveys: self-regulated learning
RQ4 (Paper in preparation)
• Adaptive turns: reflection level not achieved, explanation too short, “fake
reflection”, empathic reactions, assessment comment
