The learning design is displayed as a sequence of teaching and learning activities (TLAs) and shows all the main properties of the design you have created, such as topic, number of students, aims, outcomes, and duration of the learning time. It is a really useful tool in order to reflect about the planned activities and to determine whether or not your design is supporting the type of learning experience you have in mind.
You can access the Learning Designer through this link: http://learningdesigner.org/ (you will have to register, creating your own account)
Click on the image to access to my first learning design, it's about Sound. As you can see, the Learning Designer offers useful visual feedback through the graphical analysis of the learning experience
