This semester I am teaching a basic geometry course for design students (interior and industrial), which I am making strongly project-based since I believe they need to learn how to use geometry "in the field" rather than do too many constructions and proofs on paper.
As a result, it doesn't seem appropriate to feature traditional exams heavily, but at the same time I do want to ensure that people become proficient at basic algebra and geometry, so I need something to fill the role of exams. I was thinking about using Khan Academy badges, but when I go in there to take a look, it appears impossibly broad and complicated to use, and I can't figure out whether there is some streamlined way to have someone earn a badge in, say, lines and slopes without wading through an infinity of questions about subtracting two decimal numbers, scrolling through knowledge maps, etc etc.
I'm a bit lost! I still like the concept of badges. I'm not sure if I am missing something, or if Khan Academy just is (what seems to me in light of my intended use) cumbersome by nature and perhaps not best suited to my purpose. Has anyone used Khan or similar for the purpose I have in mind? What was your experience?
Thank you, and happy new year!
EDIT: I realized I should have clarified that these are undergraduate interior and industrial design majors at a polytechnic institute.
