STEM (Science, Technology, Engineering and Mathematics) is a methodology that raises in the development of skills, such as: research, creativity, critical thinking, problem solving, communication and collaboration, that prepares children in the school stage. This research work aims to determine how the STEM methodology application affects integral learning. The sample consists of 27 primary education second grade students in a private school in Lima Norte-11 men (40.7%) and 16 women (59.3%), between 7 (88.9%) and 8 (11.1%) years old-. The results of the correlation and simple linear regressions allow us to conclude that the development of communication, collaboration, creativity and research (typical of STEM) predict the obtaining of integral learning in students.
