When first doing this work, I used the conventions of successful graphic design to lead my suggestions. I would say, “Make it bigger, simplify your color, don’t use Comic Sans!” I learned the hard way. A teacher’s visual choices are embedded in preference, years of habit, and the culture of conventional school language. I have come to learn that most teachers make choices based on care and careful planning. If his intention in the right place, I need to work from this space, not erase it. The best I can offer is to help him see his practice in the mirror of his students perception using my expertise to help guide.
