I am not sure how many of you have seen Wunderlist (it's an app as well as online) but I wanted to take a few minutes to show the organizing tool to you.
I added the Wunderlist app to my iPad a few years ago and I decided to start using it for a method of organizing my collection development. When I preorder a book, I add it to the list with the day it comes out and I add a note about where I ordered it from. I keep all of my records of orders on a spreadsheet, but, a spreadsheet isn't going to remind me of the day I should start seeing it arrive.
Wunderlist allows you to put notifications on your desktop, like a calendar and it will popup a reminder when you are close to the deadline. It allows for a reminder and a due date.
It is also a great tool to show students so they can learn to task manage. Task management on project based learning is very important and using a tool such as Wunderlist can really help them learn to organize and plan their tasks. What is awesome about the tool is the capability of inviting friends to the tasks. So, if you, as the teacher assign a project, you can invite all of your students to the different tasks and they will get the notifications and be able to refer to the assignment on their own.
If you are in the need of becoming more organized, take a look at this site. It offers a lot of possibilities for your classes or you.
