摘要：Circle, ellipse, parabola, hyperbolic curves are defined as conic sections from the
intersection of a coni with a plane at different angles. These curves can be found in different
positions depending on the different angles. In this case, rotation transformation can be applied to
the curves so that their major axes are brought to the horizontal position. The purpose of this study
is to identify the problems experienced in using mathematics teacher candidates' rotation
transformation in conic sections and to develop solution proposals for these problems. 40 teacher
candidates participated in this study. An action plan has been designed and implemented by the
researchers in order to solve these problems by starting from the problems experienced by the
prospective teachers. At the end of the study, it was determined that the success of the teacher
candidates drawing the graphs of the curves was increased.
