Three things to check out
Changing your password(s)
How long have you had the same password? How many of your digital accounts have the same password?
The regular changing key passwords should be part of your 'digital hygiene' routine. As educators we should be modelling such practices to the students we support.
Locking your laptop
It is bad practice to leave your laptop (or any digital device) unlocked in spaces where there are are many others - such as a staffroom or classroom.
If you are moving away from your laptop for any period of time - it is really easy to lock it. Just press the Windows key and L together and your laptop is locked until you enter your password again.
If you are using a Chromebook - either use the lock key (it has a padlock on it) or press the Magnifying Glass key + L on your keyboard.
Kami - web based PDF annotation and manipulation
Kami is a great web based app for the annotation and manipulation of PDF documents and the like. It works really well with the stylus on the Yoga style devices that a lot of you use.
Kami has huge potential as a digital whiteboard. Try using your laptop in tablet/Yoga mode, protecting to the classroom screen via the Windows Wireless Adapter (HDMI 2) and see how well writing your laptop's stylus is in Kami. Open a PDF document in Kami and then try annotating/highlighting etc using Kami and your stylus. Feedback welcomed about Kami as we consider a possible future subscription.
