Seasoned profs prepare students for advanced learning

11.06.2010
But students' evaluations reward immediate gratification

Highly credentialed and experienced professors are better at preparing students for long-term academic success than their less-experienced counterparts, but that ability isn't necessarily reflected in their students' teaching evaluations. That's according to research by a pair of economists published in this month's Journal of Political Economy.

The study's authors, Scott Carrell of U.C. Davis and James West of the U.S. Air Force Academy, say their results raise questions about the value of student evaluations as measures of instructor quality.

Student evaluations are widely used by colleges in tenure and promotion decisions, but Carrell and West considered a different measure of instructor quality. They looked at how well instructors in introductory courses prepare students for more advanced courses in related subjects.

Their data come from Calculus I and follow-on classes at the U.S. Air Force Academy. All Air Force Academy students are required to take Calculus I, Calculus II, and nine math-based technical courses regardless of their majors, and professors in all sections of classes use an identical syllabus and give identical exams. That gives the researchers a chance to compare instructors on a relatively even playing field.

The study found that students' achievement in follow-on coursework was strongly influenced by their Calculus I instructor. Students who had a seasoned Calculus I professor with a Ph.D. tended to do better in follow-on coursework than students who had less-experienced and less-credentialed Calculus I instructors. This happened despite the fact that students of seasoned professors tended to have lower grades in Calculus I. The results, the researchers say, suggest that less experienced instructors have a tendency to "teach to the test," while more experienced teachers produce "deep learning" of the subject matter that helps students down the road.

The findings weren't a result of newer professors being "easy-graders," because the Calculus I course was designed to remove as much instructor discretion as possible from their student's grades. Midterm and final exams are group graded, where one instructor grades a single question for the entire course to ensure uniformity of partial credit.

The deep learning produced by more-experienced instructors was not reflected in their students' teaching evaluations, the study found. Less-experienced instructors—whose students tended to do better in the short-term but worse in later classes—received higher ratings on student evaluations. For example, the instructor who ranked dead last in "deep learning" in the sample of 91 Calculus I instructors ranked sixth best in student evaluations.

Taken together, the findings imply that student evaluations give instructors—especially those who do not have tenure—incentive to teach in ways that "have great value for raising current scores, but may have little value for lasting knowledge," the authors conclude.

Scott E. Carrell and James E. West, "Does Professor Quality Matter? Evidence from Random Assignment of Students to Professors." Journal of Political Economy 118:3 (June 2010).

One of the oldest and most prestigious journals in economics, the Journal of Political Economy has since 1892 presented significant research and scholarship in economic theory and practice. The journal aims to publish highly selective, widely cited articles of current relevance that will have a long-term impact on economics research.

Im Focus: Interfacial Superconductivity: Magnetic and superconducting order revealed simultaneously

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.

While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...

Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...

Im Focus: Designing Architecture with Solar Building Envelopes

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.

As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...

Im Focus: How to inflate a hardened concrete shell with a weight of 80 t

At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).

Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...

Im Focus: Bacterial Pac Man molecule snaps at sugar

Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.

The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
