Beneficial Strengths

This projector definitely has a number of advantages that would outdo most other visual teaching aids. For instance, a lecturer can use it in just the same way that he or she would use a chalkboard, but the biggest advantage would be that with the projector, lecturers all over the world now get to face the whole class and maintain eye contact all times with their students instead of having to turn around and write. As a teacher, you would know that this eye contact plays a very big role in both facilitative as well as expository teaching, and serves both as a means of receiving feedback from the class on how good or bad the session is and as an outward non verbal communication medium for the teacher.
