Hi,

I agree with Bianca here, class sizes of 20 (2 instructors + 2 helpers) work nicely, and I also would not go above 30 (with more helpers in this case 3-4). This is perhaps only marginally relevant, but I have been struggling to book rooms (at Uni of Manchester, UK) that can comfortably fit 30 (let alone > 30) people with enough room for helpers to move around and reach and talk to trainees without disturbing the rest of the class and for trainees to see the screen at the front properly (but this may be a limitation of rooms we have at our disposal here).

Anything below 20 is possibly not such a good use of resources (instructors' and helpers' times), even though I did workshops for ~15 people from the same cohort in a nice and friendly environment.

Regards,
Aleks

Hi Maneesha,

From past workshop experience (n=5), a class size of 20 has worked the best (in my opinion). For this class size, 2 instructors and 2 helpers were enough, since the one instructor usually helps while the other one teaches. However, it's important to keep in mind that one of the helpers might need to run/drive around to handle crises.

Then again, on request, I did a one-day R workshop all by myself (I forgot to ask for helpers) with 15 participants, and I was able to manage it. However, there weren't a lot of questions and most of them just wanted to "have a look at R" and were not necessarily interested in using this post-workshop.

Personally, I would not run a workshop with more than 30 people, because, as you said, the workshops should be engaging and interactive.

Hope this helps!

    Hey all -

    As I think about Carpentries workshop operations, I have a
    question for discussion.

    What's your ideal Carpentries class size?
    Assume 2 instructors and a 1:10 helper:learner ratio (3 people
    total for a class of 10, 4 people total for a class of 20, and so on)
    We want our workshops to be engaging, hands on, and interactive. 
    Is there a lower limit to this, where it doesn't seem big enough
    to worthwhile in those ways?
    And is there an upper limit, where it's too big to be worthwhile
    in those ways?

    Perspectives from instructors, hosts, helpers, and learners are
    welcome!  Feel free to reply all or email me directly.  Thanks for
    your feedback.
