Critical thinking is a skill that most faculty members would readily agree is important for students to develop. Unfortunately, many of our students have poorly developed critical thinking skills (Rudd, Baker, Hoover, Gregg, 1999). Perhaps the problem is rooted in us, the faculty. Do faculty members understand the concept of critical thinking well enough to teach students to think critically in and about the discipline being studied? This paper is an attempt to define critical thinking for college of agriculture faculty members and to offer a primer for discussion of strategies to teach students to think critically in agricultural disciplines.
