It is very important to incorporate technology in the classroom. Technology in the classroom can increase student involvement and understanding of key concepts. Students are more likely to want to participate when technology is involved in a well-made lesson. Also, technology can allow for the easier creation of lessons and other materials, which reduces prep time.
The challenges are that a school might not have the necessary technology or it might not function properly when you go to actually teach the lesson.
Some of the things I will take with me from this class are: always be open to new technology, use all available resources in order to make the task at hand easier (as with the fill-in lesson plan), and to use technology in order to make sure my class is unique to my personal style.
