Conceptual framework:
I believe Instructional design program contains three main concepts:
Instructional technology strategies, Educational theories and pedagogical models, and Design and web authoring tools.

The lower section which is completing the graph is a web-design and authoring tools section. This section contains several elective classes the offered to help potential instructional designer to present their work and final design using web-design, integrative, animations authoring tools programs such as Dreamweaver, Photoshop, Captivate, and Flash. etc..
Although these programs are not essential for to be an instructional designer, a good designer is able to manipulate computer programs to present his design ideas. Also understanding these programs’ features could help designers in their thinking and developing the new design.
