Last week was Linux Kongress. I started out with a 6 hour hands-on tutorial on SE Linux. This didn't go as well as planned for a number of reasons. One problem was that on the day before when starting to prepare I didn't power on all the machines, so on the day of the tutorial when I turned them all on the circuit-breaker tripped. :( So we had lots of power outages with an end result of having no power and not having the image installed to the hard drives at the appointed start time. Fortunately my network-install setup was pretty smooth and I had all 16 machines up and running within 30 minutes of power being restored. Unfortunately in my haste I had omitted some packages of software from the hard drives of the machines, so I put them on the FTP server of my laptop. Some confusion was caused by this and by the fact that I had included full file names (including version numbers) of the packages (and I had developed new versions between the publication date and the day of the tutorial). Another problem was that the notes weren't as clear as they could have been (I have not written such a document before). The biggest mistake I made was lack of repitition. If something was mentioned in the previous section then I would not mention it again, I now believe that for a tutorial every section should start with "After doing foo which we learned in the previous section we will continue to do bar" or something similar. EVERY student failed to edit the default_context after creating a new role, I had presumed that they would have recalled it from the section on adding a new user. Whenever the majority of students fail to learn it's because the teacher has made a mistake, this is something I'll have to be more careful about in future. The next issue was that I had planned for students to give accounts to other groups and to be able to monitor and control them while they are logged in. However no two groups were at that stage at the same time and everyone skipped it. For future tutorials I plan to use NBD or some similar technology to store the data on the network. Then at a snack break they can change machines such that groups at a similar skill level can cluster which will allow them to perform such tasks. However the tutorial went quite well apart from these problems. I was very surprised by the rate at which they learned, as some time was removed by the lack of power which corresponded to the section they skipped, so at the appointed end time everyone had finished the work. I was actually surprised by how well the audience learned some of the concepts, I hadn't expected that everyone would complete the work in the time alotted. I was glad to have such an intelligent group of people to teach!
