In the primary and secondary stage is very important for teachers who use the method of observation because from this stage it is possible to determine which hemisphere has more development a student, there are two hemispheres as right hemisphere and left hemisphere, but each hemisphere is dominant for different behavior. While the right hemisphere is responsible for controlling creative and artistic abilities such as space skills, facial recognition, music as well as controlling the left side of the body. The left hemisphere is responsible for controlling academic and logical abilities such as calculus, math, literature, and control the right side of the body (Wolman, May 12, 2012).Â However, the two hemispheres share information through the callous body. For these reasons, it is important for teachers who use the observation technique, when using this technique, and determining which hemisphere has less developed the teacher must use certain strategies to awaken the part of the brain less developed.Is necessary take into account that in primary and secondary stage is when the student has more creative capacities that an adult person for this reason is very important to work in student's skills, for example when the people are adults have loosed the creativity capacity so when the people want to run companies, they have many scary to lead their companies because they think that possibly fail (Robinson. K, 2006). In this stage is important that the student add creativity because in this moment because how in the video "do school kill Creativity?", (Robinson. K, 2006) Ken Robinson says that "Picasso said: "all children are born artists. The problem is to remain an artist as we grow up." I believe this passionately, that we don't grow into creativity, we grow out of it". For these reason is very important consider the creativity with the science. then the professors would be who infuse this meaning all the days in their classes.
