Student and Teacher Roles with Technology

An idea I've come to find very interesting is the notion that many teachers and faculty roles are beginning to change due to technology and all that comes with it. After reading some recent information I found on an education site this concept is one to truly consider. The information demonstrates that teachers' roles are shifting and it's because of technology.
The information suggests that through the advancement of technological devices, the attention teachers receive in a learning environment or classroom no longer exists. Students are allowed the ability to make decisions and perform tasks through actively thinking and learning.
In return, teachers roles change from being the primary source for information and become facilitators. In the role of a facilitator the site says, "...setting projects and providing guidelines and resources, moving from student to student or group to group, providing suggestions and support for student activity." The article also states that the teacher has the opportunity to look over students shoulders, ask questions about reasons for particular designs, ideas, etc. or even what resources were utilized.
When determining the roles of students and teachers I completely agree and understand how the role of teachers and professors have changed. In some ways, this role reversal is an advantage for students especially those who are hands-on type of learners. Then again, this minimizes in some ways the authority of the teacher/professor in the classroom.
