Instructional Technology

Here are my personal definitions of the following terms.  I feel that the definitions are fairly basic and traditional.

Technology:  The use of tools (i.e. materials, resources, ideas) to further a purpose.

Instructional Technology:  The use of tools to help someone: 1-better understand a concept, or 2-become more skilled in a particular action.

Learning Sciences:  The study of: 1-how people become more proficient in performing a skill, or 2-how people increase their understanding of a concept.

I have worked in construction for many years and love to use the "traditional" tools like hammer and nails.  The more I use these, the more I can understand the abstract definition of technology.
