This curriculum uses the Minnesota Framework for Universal Multicultural Instructional Design as its design reference, and that framework lines up closely with universal design for learning. Stripped of the vocabulary, both say the same practical thing: decide up front that the people using this will vary, and build for that range, instead of building for an imagined average person and then handling everyone else as an exception.
Universal design for learning names three places variation shows up. Engagement: what makes this worth someone's attention, which differs by role, by pressure and by how the subject touches their work. Representation: how the substance is presented, so that reading, listening, seeing a structure and working through an example are all available rather than only one of them. Action and expression: how a person works with the material and shows themselves they have it, which in a voluntary program means optional practice and private reflection rather than a score.
The Minnesota framework adds the part that is easy to skip. Materials carry cultural assumptions in their examples, their names, their scenarios, their idioms and their picture of what a normal situation looks like. A case story set entirely in a suburban two-parent household with reliable transportation and a landline is not neutral; it is one context presented as the default. Designing across contexts is not decoration. It decides whether a reader recognizes the situation well enough to apply the guidance at all.
Both of these are ordinary craft, not ideology. They are also the difference between designing for sameness — one version, equally available, which the continuum calls Minimization — and designing for the actual range, which is what Adaptation looks like in this kind of work.
