"computational STEAM learning" = (1) + (2), where

(1) STEAM +

(2) Computational thinking

where STEAM is the usual standard educational approach which combines

"Science, Technology, Engineering, Arts and Mathematics" for developing critical thinking, problem solving skills, etc.

and

Computational thinking

can be supported by an old book in Computational Theory like

"An Introduction to Computational Learning Theory" (1994) by Kearns and Vazirani

or course notes like

Computational STEAM learning refers to learning approach that integrates Science, Technology, Engineering, Arts and Mathematics (STEAM), with computer skills like coding and problem-solving.
