This book was created by members of the DEHAES (Spatial Skills Development) research group at the University of La Laguna. It is designed to provide practical graphic expression activities in STEAM (Science, Technology, Engineering, Art, Design, and Mathematics) environments. It is intended for subjects that commonly involve project-based learning. In other words, it is suitable for both engineering and more creative environments such as art and design. Likewise, the proposed activities can be used at the university level as an introduction to graphic expression or at the secondary and high school levels.
