How Did the Egyptians Transport the Stone Blocks of the Pyramids?

Abstract

The new trend in the Spanish educational system towards the teaching-learning of STEM skills makes it necessary to reinforce both didactic and contents of the different STEM areas. A STEM experience with simple machines was designed for 115 pre-service elementary teachers, being all students of the 4th grade in primary education in the context of a subject of didactics of experimental sciences. After the completion of the intervention, hard difficulties with several concepts were identified in participants, especially those related to mathematics (measurement of angles, concepts of trigonometry, graphic representations). These difficulties should be addressed in initial teacher training with the aim to improve their future professional performance as STEM teachers.
