I don&#x27;t think objectivity and salesmanship are mutually exclusive. I&#x27;ve seen teachers make learning material really interesting without having to sacrifice neutrality. They simply make me care about the material - good or bad.<p>OP seems to be encouraging teachers to &quot;sell&quot; the idea that the material they&#x27;re teaching is important. If you don&#x27;t make someone emotionally investing in learning the material, they&#x27;ll forget 60% of it (on average). If you don&#x27;t sell the material, it won&#x27;t matter whether you were completely objective because students will forget most of what you taught them.<p>I agree that it&#x27;s really important for teachers to encourage critical thinking. I just think that it&#x27;s possible for teachers to encourage critical thinking while still selling the fact that you should care about the material.
