| Popis: |
This paper reports a study conducted with 19 student-teachers. Our objective was to investigate how student-teachers graphically view the concept of tangent to a curve on a fixed point. An interpretative approach revealed that the student-teachers had a global perspective of the concept, which reflected a strong influence of the tangent to a circumference. |
