The purpose of this study was to investigate how effective the pedagogical education was from the perception of mathematics teachers whose bachelor degree was from mathematics department of science faculty. For this purpose, as a sample, 15 mathematics teachers who had at least two year teaching experiences before taking pedagogical education were chosen with convenience sampling method. With the semi-structured interviews, their perceptions about special instructional techniques, developmental psychology, and curriculum development courses were gathered. In general, the results of this study revealed that teachers perceived that this education was required for all teacher candidates. On the other hand, it was found that there was a difficulty to apply what was learnt in these courses into practice in classroom environment due to various reasons.
