The acronym STEM came from US National Science Foundation. It is acronym from words Science, Technology, Engineering and Mathematics (STEM). STEM is educational approach, which helps to show interdisciplinary links between sciences, technology and engineering. 

In using variations of it:

STEMLE (Science, Technology, Engineering, Mathematics, Law and Economics); identifies subjects focused on fields such as applied social sciences and anthropology, regulation, cybernetics, machine learning, social systems, computational economics and computational social sciences.

Variations of STEM

METALS (STEAM + Logic)
STREM (Science, Technology, Robotics, Engineering, and Mathematics); adds robotics as a field.
STREAM (Science, Technology, Robotics, Engineering, Arts, and Mathematics); add robotics and arts as fields.
STEAM (Science, Technology, Engineering, Arts, and Mathematics)
STEAM (Science, Technology, Engineering and Applied Mathematics); more focus on applied mathematics
GEMS (Girls in Engineering, Math, and Science); used for programs to encourage women to enter these fields.
STEMM (Science, Technology, Engineering, Mathematics, and Medicine)
AMSEE (Applied Math, Science, Engineering, and Entrepreneurship)
THAMES (Technology, Hands-On, Art, Mathematics, Engineering, Science)

We use shorter abbreviation STE, because Mathematics is an integral part of Science, Technology, Engineering.

In the STE BLOG we will collect and publish articles which could help educators do learning memorable. It will include articles about education products, use cases and introduction ideas.
