As usual Andrea provided lots of ideas and links to online tools.  I love this site that I have never seen before – it is an online journal -but it is private, so there for you to access and add to when you want to.  You can get e-mail reminders to update your journal – imagine how great this could be in Technology as a record of what students have done in each session.  You can add images and links etc.

It lets you know things like how many words you have typed too!  I have only just started using this – but it looks hugely valuable in many areas of the curriculum!  Love it!
