Do majors matter? Since students typically spend more time in their area of concentration than anywhere else in the curriculum, majors ought to live up to their name and produce really major benefits. But do they?
Anthony P. Carnevale, the Director of Georgetown’s Center for Education and the Workforce, had recently provided a clear answer. Majors matter a lot -- a lot of dollars and cents. In a report entitled “What’s it Worth,”  he shows how greatly salaries vary by major, from $120,000 on average for petroleum engineers down to $29,000 for counseling psychologists.
But what if one asked whether majors make differing contributions to students’ cognitive development? The answer is once again yes, but the picture looks very different from the one in the Georgetown study.
A few years ago, Paul Sotherland, a biologist at Kalamazoo College in Michigan, asked an unnecessary question and got not an answer but a tantalizing set of new questions. It was unnecessary because most experts in higher education already knew the answer, or thought they did: as far as higher-order cognitive skills are concerned, it doesn’t matter what you teach; it’s how you teach it.
What Sotherland found challenged that conventional wisdom and raised new questions about the role of majors in liberal education. Here’s what he did. Kalamazoo had been using the Collegiate Learning Assessment (CLA) to track its students’ progress in critical thinking and analytical reasoning. After a few years it become clear that Kalamazoo students were making impressive gains from their first to their senior years. Sotherland wondered if those gains were across the board or varied from field to field.
So he and his associates tabulated their CLA results  for each of the five divisions of the college’s curriculum  -- fine arts, modern and classical languages and literatures, humanities, natural sciences and mathematics, and social sciences.
Since gains in CLA scores tend to follow entering ACT or SAT scores, they “corrected” the raw data to see what gains might be attributed to instruction. They found significant differences among the divisions, with the largest gains (over 200 points) in foreign languages, about half that much in the social sciences, still less in the fine arts and in the humanities, least of all in the natural sciences .
How was this to be explained? Could reading Proust somehow hone critical thinking more than working in the lab? (Maybe so. )
But the sample size was small and came from one exceptional institution, one where students in all divisions did better than their SAT scores would lead one to expect, and where the average corrected gain on CLA is 1.5 standard deviations, well above the national average. (Perhaps Inside Higher Ed should sponsor the “Kalamazoo Challenge,” to see if other institutions can show even better results in their CLA data.)
The obvious next step was to ask Roger Benjamin of the Collegiate Learning Assessment if his associates would crunch some numbers for me. They obliged, with figures showing changes over four years for both parts of the CLA -- the performance task and analytical writing. Once again, the figures were corrected on the basis of entering ACT or SAT scores.
The gains came in clusters. At the top was sociology, with an average gain of just over 0.6 standard deviations. Then came multi- and interdisciplinary studies, foreign languages, physical education, math, and business with gains of 0.50 SDs or more.
The large middle cluster included (in descending order) education, health-related fields, computer and information sciences, history, psychology, law enforcement, English, political science, biological sciences, and liberal and general studies.
Behind them, with gains between 0.30 and 0.49 SDs, came communications (speech, journalism, television, radio etc.), physical sciences, nursing, engineering, and economics. The smallest gain (less than 0.01 standard deviations) was in architecture.
The list seemed counterintuitive to me when I first studied it, just as the Kalamazoo data had. In each case, ostensibly rigorous disciples, including most of the STEM disciplines (the exception was math) had disappointing results. Once again the foreign languages shone, while most other humanistic disciplines cohabited with unfamiliar bedfellows such as computer science and law enforcement. Social scientific fields scattered widely, from sociology at the very top to economics close to the bottom.
When one looks at these data, one thing is immediately clear. The fields that show the greatest gains in critical thinking are not the fields that produce the highest salaries for their graduates. On the contrary, engineers may show only small gains in critical thinking, but they often command salaries of over $100,000. Economists may lag as well, but not at salary time, when, according to “What’s It Worth” their graduates enjoy median salaries of $70,000. At the other end majors in sociology and French, German and other commonly taught foreign languages may show impressive gains, but they have to be content with median salaries of $45,000.
But what do these data tell us about educational practice? It seems unlikely that one subject matter taken by itself has a near-magical power to result in significant cognitive gains while another does nothing of the sort. If that were the case, why do business majors show so much more progress than economics majors? Is there something in the content of a physical education major (0.50 SDs) that makes it inherently more powerful than a major in one of the physical sciences (0.34 SDs)? I doubt it.
Since part of the CLA is based on essays students write during the exam, perhaps the natural science majors simply had not written enough to do really well on the test. (That’s the usual first reaction, I find, to unexpected assessment results -- "there must be something wrong with the test.") That was, however, at best a partial explanation, since it didn’t account for the differences among the other fields. English majors, for example, probably write a lot of papers, but their gains were no greater than those of students in computer sciences or health-related fields.
Another possibility is that certain fields attract students who are ready to hone their critical thinking skills. If so, it would be important to identify what it is in each of those fields that attract such students to it. Are there, for example, “signature pedagogies” that have this effect? If so, what are they and how can their effects be maximized? Or is it that certain pedagogical practices, whether or not they attract highly motivated students, increase critical thinking capacities – and others as well? For example, the Wabash national study  has identified four clusters of practices that increase student engagement and learning in many areas (good teaching and high-quality interactions with faculty, academic challenge and high expectations, diversity experiences, and higher-order, integrative, and reflective learning).
Some fields, moreover, may encourage students to “broaden out” -- potentially important for the development of critical thinking capacities as one Kalamazoo study suggests. Other disciplines may discourage such intellectual range.
One other hypothesis, I believe, also deserves closer consideration. The CLA is a test of post-formal reasoning. That is, it does not seek to find out if students know the one right answer to the problems it sets; on the contrary, it rewards the ability to consider the merits of alternative approaches. That suggests that students who develop the habit of considering alternative viewpoints, values and outcomes and regularly articulate and weigh alternative possibilities may have an advantage when taking the CLA exam, and quite possibly in real-life settings as well.
Since the study of foreign languages constantly requires the consideration of such alternatives, their study may provide particularly promising venues for the development of such capacities. If so, foreign languages have a special claim on attention and resources even in a time of deep budgetary cuts. Their "signature pedagogies,"  moreover, may provide useful models for other disciplines.
These varying interpretations of the CLA data open up many possibilities for improving students’ critical thinking. But will these possibilities be fully utilized without new incentives? The current salary structure sends a bad signal when it puts the money where students make very small gains in critical thinking, and gives scant reward to fields that are high performers in this respect . (For example, according to  the College & University Professional Association for Human Resources, full professors in engineering average over $114,000, while those in foreign languages average just over $85,000.
Isn’t it time to shift some resources to encourage experimentation in all fields to develop the cognitive as well as the purely financial benefits of the major?
