Professor Wadsworth has been in administration for 27 of his 40 years at the university, a period in which he has produced 26 M.S. degrees and 42 Ph.D. degrees. "An important measure of his success as a teacher," a colleague wrote, is the quality of his products. His former students have been highly successful and pay tribute to him as a teacher." His teaching has included courses in advanced mineral dressing, physical metallurgy for undergraduates, x-ray diffraction, and physical chemistry of extractive metallurgy.
