This is just one of many interesting points made in the article and this is coming from an English guy:
Math teachers in the U.S. have the world's hardest job, because opinions about the subject are already stacked against it. Over the years, the humanness and relevancy of math have been squeezed out, and students no longer see its significance. To get students engaged in math again, we have to add the human element back.That is at times the way that I feel about trying to teach grammar. The article has many good ideas and I found that the idea of teaching math poorly is one of the main drivers preventing people from getting into STEM fields.
