According to General Statistics Office of Vietnam on 30th September, 2017, Vietnam has 858,800 teachers, and among those, 615,720 people were female (occupied 71.7%). It can be seen that female teachers made up a big percentage in the education sector. Besides, STEM education is soaring as a new approach in training with prominent advantages, such as: theories embedded in actual practices, ability-oriented development, pressure reduction in studying… This is not only a trend but also a necessary element in new teaching modules at high school -- which will be implemented in academic year 2020-2021 in Vietnam. As a result, it is necessary to consider the gender factor in the process of training and developing teaching with STEM education. This paper will present the results from the research that took place from 2015 to 2018 within Thai Nguyen University of Education.
