Hi Barry: Great! For me, "sufficient" content means all that is required to meet course and student learning objectives. There can be more, but the basic, essential content has to be there. Using building a house as an example, shoddy workmanship and not meeting codes might exemplify non-sufficient. Meeting all codes, safe structual foundations, and functional design might illustrate the house that is sufficient (comfortable and meets all the needs of the occupants). Then, you might have executive, luxury or extravagant type homes. These provide residential structures that, really are in excess of what one really needs. Not that they're not desirable or useable, but consistent with my example, they are beyond sufficiency. So, as long as the essential, necessary content is provided, anything beyond that is adjunctive to what's needed. Regards, Barry
