I previously wrote a few musings about time management for teachers using ICT, online teaching, etc.
As Elek has pointed out, there is no ideal solution. I believe a lot of people use the style he mentioned, staying online most of the day and communicating often. It dovetails with the comment about “striking while the iron is hot”, i.e. sending email, blog post, etc. as soon as the lesson is over.
I do also find it very effective to write about a lesson, whether to students or just in my own notes, as soon as the lesson is finished.
If one teaches onsite as I do, traveling from company to company during the day, it means there is little chance to go online between lessons. Therefore, I am experimenting with several different formats. I block out an afternoon for blogging, wiki maintenance, and email with students (the drawbacks of this have been pointed out!) I could spend a few minutes on this every evening – the minutes of course can become hours. Or I could earmark a part of my weekend for such.
Now I have just hunted around for ideas from blogging teachers and found one person who firstly mentioned it is not necessary to check/write emails repeatedly during the day. Twice a day is plenty, says he. I think he may have a point; at least, when it comes to time management, checking email frequently is a really bad way to interrupt yourself and subvert a good plan. Secondly, this blogger mentions sorting tasks according to whether you need to be online to do them or not. If you have to write for example, you don’t necessarily have to be online to do it.
Finally, I think Nigel Marsh’s concepts of Work-Life Balance may apply here. He says we can be much happier if we don’t let our work rule us. I think that’s true here, too. Maybe I’ll approach this from the other side: which of my groups/individual students would benefit most from having their own blog/wiki, and who can I just email from time to time? I may even shut down a few superfluous things.
