ISGE uses the SAME themes throughout the curriculum. A theme is defined as “an idea that recurs in or pervades a work of art or literature” (Google definitions) (but in this case pervades presentations of key science phenomena).
The core of the ISGE curriculum are the Isomorphic Systems Processes (ISPs) from the Systems Processes Theory (SPT). They are Isomorphic because they have been found to be present across many phenomena of nature so they are Nature’s Enduring Patterns, a book by the ISGE author. Since they are mechanisms that are similar in many differing disciplines (or the systems they study), we consider them to be INTEGRATIVE and UNIVERSAL. So for the purposes of the ISGE curriculum, we call them here, “INTEGRATIVE THEMES” or IT’s. Themes because they present across the curriculum. There is no need to burden the students with the technical terminology, often called derisively “jargon,” of the professional research area that might be titled natural systems science.
They are isomorphic because the are the same despite differences in size scale, disciplines that study them, dates of origin, parts they are composed of, how the parts interact on the local level, and xxxxx. We are borrowing the best and most supported of these mechanisms of how systems of all kinds work from the much larger list of possible Integrative Themes.
