Definition of Instructional Design

Hi friends.
I am inspired by the developments in my personal as well as professional life. Now, it is time to begin sharing my knowledge. The knowledge I have acquired by learning and experience. I do not want my blog to be written and updated only by me. I want comments and views to improve my understanding too. I want this to be an open source forum. I will begin by defining instructional design.
Instructional Design: Instructional design is the systematic design and development of instructions to ensure that the learning need of the learners are fulfilled. To know more definitions, follow the hyperlink:
