## CodeRefinery workshop: Why Reverse hybrid

- **Issue with hybrid:**
     - People onsite ≠ people online.

- **Large courses:**
     - Most students don't have time to ask a question f2f
     - They online chat with the teacher anyway

- **Reverse hybrid:**
     - Teachers via video and online chat
     - Students in onsite groups
     - Those who want interaction can get it
     - The course isn't bound to one location, anyone can attend.

- *It is actually scaling up!*
- **First challenge:** Explain how to join :D

## Scaling up – Technical side

## Scaling up – Technical side

- **Many moving parts:**
     - Screenshare material and terminal / Jupyter
     - Zoom + OBS: audio and video in both (mute, on/off…)
     - Sound levels have to be checked with every speaker
     - Different scenes to screensharing, discussion, breaks…

- **New bottlenecks:** 
     - What we worry the most: The Q&A document
          - We get up to 40 questions per hour
          - Collaborative document might crash
          - User errors: someone selects all and delete…
          - Needs a few people to moderate

     - *More people* -> more technical problems -> overhead in solving them

## Scaling up – Challenges

- **Preparation and afterwork**
     - *Coordination effort* > lesson preparation and teaching
     - *We removed Zoom teams*
     - Volunteer retention and building lasting relationships takes effort

- **More people:**
     - Level of teaching: 
          - No common prerequisite level
          - Take the novices into account -> Again a basic course
     - Meeting expectations: 
          - Walkthrouhgs vs. proper problem-solving exercises

- **Remote people:**
     - How to ensure a common understanding about the topic
     - How to know how people are doing?
          - We don't see them, but the Q&A document
     - Certificates: how do we assess what people have been done?
