Résumé
A study was conducted with a high school algebra teacher and her students with the purpose of gaining insight into the students’ difficulties with perpendicular lines. The study reported here focuses on the communication between the teacher and her students, and the nature of their messages. Classroom observations were conducted, and a written task was administered to students. The communication was analyzed using constructs from Hall’s theory of culture. The analysis revealed that the teacher’s messages were not received by her students in the way intended by the teacher. The students had difficulties defining perpendicular lines, representing graphically and characterizing them algebraically, and connecting between representations.
