The Teacher Is A Catalyst
In a Montessori classroom, the teacher is the catalyst that activates the relationship between the child and the “prepared environment.” She shows the child, she does not tell him. She helps the child focus his attention, she demonstrates materials to him, and then she allows him to work on his own. She shows respect for the child by not getting in the way of his self-discovery. A Montessori teacher does not push a child, but rather follows the child’s lead. By constantly observing, she stays aware of the needs and abilities of each child. She will “invite” a child to learn by introducing new materials appropriate to his or her stage. She nurtures the child’s natural unfolding through modeling and demonstrating.2. Which words cannot change the underlined word? (2points)
