Video Math Instructors Replacing Us!!!

I think that math teachers are going to be the last teachers that will be replaced by technology. Mathematics is a subject that can become very confusing and must be explained. Throughout my experience thus far observing and teaching all of the students need math reiterated in a way in which they can understand it. The student to teacher interaction in the classroom is crucial in the success of the students understanding the material. I feel that by putting on a video is a good idea, but what happens when students do not understand what the instructor in the movie teaches? The administrator in the classroom will then have to explain the mathematics in a different way to the students taking up precious time that neither the teacher nor the students can afford.
I believe other subjects such as history or psychology will be replaced first with this idea of using such technologies. In these subjects the material is more about facts and information than it is about problem solving and critical thinking. One reason to ensure me that my job will not be replaced is that in a worse case scenario I would still be a classroom administrator to proctor my classroom. I am sure I would still be teaching, it would just be in a different way. My number one concern is what is best for my students’ education. If results show that using this technology is more beneficial for the students learning than I would be content with being a classroom administrator because I want the best possible education for my students.
