The purpose of this study was to compare the challenges faced by new K-12 mathematics teachers (MTs) and new mathematics teacher educators (MTEs) and use what is known about supporting new K-12 MTs to begin to develop improved support systems for new MTEs. These findings show that novice mathematics teacher educators need additional and more valuable teaching opportunities throughout their preparation programs as well as mentoring experiences to help them as they transition into their new positions. These findings are consistent with literature review findings on the experiences of novice K-12 mathematics teachers. The authors conclude that these findings about the need for teaching experiences and mentorship for novice MTEs ,much like those needs identified for novice MTs, may help improve teacher education programs while also improving mathematics teacher education programs.
