Description:
The purpose of this study was to examine a preservice mathematics teacher’s weaknesses in her content knowledge and pedagogical content knowledge of the concept of function when she taught an episode on exponential functions to a group of high school students. During her planning and teaching of a lesson to the group of high school students, I observed the results of her lack of teaching experience and incomplete content knowledge on her pedagogical content knowledge. The results of her teaching experience showed the preservice secondary teacher had misconceptions and during her teaching she passed on these misconceptions to her students.
