In his POD post "Re: Problems with Student Evaluations: Is Assessment the Remedy," Ed Nuhfer (2002) hit the nail on the head:
One of the most encouraging solutions that I see out of this morass. . .[the unending tired debate -- see numbers of hits-- 762 total -- on "student evaluations" in the list of URL's above -- over student evaluations]. . . is the assessment movement. Those who object to sophisticated assessments usually ask, "Why can't we just use grades as measures of learning?" Doesn't that just echo like "Why can't we just use student ratings of professors as measures of good teaching?. . . . My hope is that, a decade from now, members will look at our discussions about student ratings in the POD archives and realize just how far people can come in ten years if they commit to breaking out of primitive conventions. . .(e.g., using mere grades as measures of learning).At the risk of replaying to deaf ears the same old record (as e.g., Hake 2000; 2002a,b,c,d), I reiterate Lesson #3 of Hake (2002c) (see that article for the references):
L3. High-quality standardized tests of the cognitive and affective Impact of courses are essential for gauging the relative effectiveness of non-traditional educational methods.Because most disciplines have failed to develop definitive tests to measure cognitive and affective course impacts, seemingly simplistic statements from the pro Student Evaluation of Teaching (SET) camp cannot always be immediately dismissed. For example:
As far as I know, disciplines other than physics, astronomy (Adams et al. 2000; Zeilik et al. 1997, 1998, 1999), and possibly economics (Saunders 1991, Kennedy & Siegfried 1997, Chizmar & Ostrosky 1998, Allgood and Walstad 1999) have yet to develop any such tests and therefore cannot effectively gauge either the need for or the efficacy of their reform efforts. In my opinion, all disciplines should consider the construction of high-quality standardized tests of essential introductory course concepts.
Although there are many SET researchers (see, e.g. Abrami et al. 1990; Aleamoni 1987; d'Apollonia & Cohen 1997; Cohen 1981; Cashin 1995; Marsh & Roche 1997; Marsh & Dunkin 1992) who claim that SETs are valid indicators of students' cognitive condition (for a review see Hake 2000), their conclusions are almost always based on measuring student learning or "achievement" by course grades or exams and not by pre/post testing . . . (pre/post even despite the Lordly Cronbachian objections of some education/psychology specialists -- see Hake (2001). . . with valid and reliable instruments such as the Force Concept Inventory of Hestenes et al. (1992) and Halloun et al. (1995) (see, e.g., Hake [2002c]).
With regard to the problem of using course performance as a measure of student achievement or learning, Peter Cohen's (1981) oft-quoted meta-analysis of 41 studies on 68 separate multisection courses purportedly showing that:
the average correlation between an overall instructor rating and student achievement was +0.43; the average correlation between an overall course rating and student achievement was +0.47 ... the results ... provide strong support for the validity of student ratings as measures of teaching effectivenesswas reviewed and reanalyzed by Feldman (1989) who pointed out that McKeachie (1987)
has recently reminded educational researchers and practitioners that the achievement tests assessing student learning in the sorts of studies reviewed here. . . (e.g., those by Cohen (1981, 1986, 1987). . . typically measure lower-level educational objectives such as memory of facts and definitions rather than higher-level outcomes such as critical thinking and problem solving . . .[he might have added conceptual understanding] . . . that are usually taken as important in higher education.Striking back at SET skeptics, Peter Cohen (1990) opined:
Negative attitudes toward student ratings are especially resistant to change, and it seems that faculty and administrators support their belief in student-rating myths with personal and anecdotal evidence, which (for them) outweighs empirically based research evidence.However, as far as I know, neither Cohen nor any other SET champion has countered the fatal objection of McKeachie that the evidence for the validity of SET's as gauges of the cognitive impact of courses rests for the most part on measures of lower-level thinking.
Williams & Ceci (1997) write:
L4. Education research and development (R&D) by disciplinary experts (DE's), and of the same quality and nature as traditional science/engineering R&D, is needed to develop potentially effective educational methods within each discipline. But the DE's should take advantage of the insights of (a) DEe's doing education R&D in other disciplines, (b) cognitive scientists, (c) faculty and graduates of education schools, and (d) classroom teachers. . . .Richard Hake, Emeritus Professor of Physics, Indiana University
The education of disciplinary experts in education research requires Ph.D. programs at least as rigorous as those for experts in traditional research. The programs should include, in addition to the standard disciplinary graduate courses, some exposure to: the history and philosophy of education, computer science, statistics, political science, social science, economics, engineering -- see Lesson 11, and, most importantly, cognitive science (i.e., philosophy, psychology, artificial intelligence, linguistics, anthropology, and neuroscience). . . . In the U.S. there are now about a dozen Ph.D. programs (Physical Science Resource Center 2001, UMd-PERG 2001) in physics education within physics departments and about half that number of interdisciplinary programs between physics and education or cognitive psychology. In my opinion, all scientific disciplines should consider offering Ph.D. programs in education research.

The abstract reads: "One purpose of students' evaluations of teaching (SETs) is for research on teaching itself. Because SETs do not reflect the valid effects of presage and context measures, it is argued. . .(evidently by others). . . that SETs may not be a fair source in the evaluation of teaching in higher education. This study examines this problem, with an emphasis on the need for a multidimensional approach for measuring effective teaching. The reliability, stability, and generalizability factors are also discussed, as are potential biases in both peer and student related evaluations. It is concluded that sets are clearly multidimensional, Quite reliable, and reasonably valid. However, caution is suggested in using SETs as a systematic approach, as SETs are yet only one indicator of effective teaching in higher education. (My emphasis.)Nuhfer, E. 2002.

"Today, all instructors would be well advised to ask their students frequently 'How'm I doing?' and listen carefully to the answer. As in politics, however, the answer may have more to do with style than substance." See also Lewis (1998) and Lang (1997).
