How to run a Workshop

For clarity we will call a Workshop a master class. We will call the attendee of the master class a student. The one who gives the master class, a teacher.

This article is about educational master classes in IT, that is, programming , testing , DevOps and so on.

If the goal of the master class is not teaching environment installation, it should be divided into two parts.

1

The first part can be done remotely as homework.

It should describe the main steps for installing and configuring the software that will be used during the master class.

If a student could not install something, they send questions to the teacher, and by the start of the second part everything is installed and working for everyone.

Antipattern

A master class on load testing is held with Locust and the students could not install it, did not open the required port, do not know how to open ports in the OS on which the master class is held.

As a result, either part of the students simply cannot go through the master class, or the time is spent not on teaching the subtleties of load testing but on banal basic environment setup, which any student can do if given such a task in advance.

The second part of the master class should contain the main content.
