The value of subjective and objective evaluations of teacher effectiveness

18.10.2011
Study finds that subjective evaluations are comparable with and complementary to objective measures of teacher effectiveness

A study conducted by Columbia Business School's Prof. Jonah Rockoff, Sidney Taurel Associate Professor of Business, Finance and Economics, and Cecilia Speroni, a doctoral student at Teachers College, set to estimate whether subjective evaluations of teacher effectiveness have predictive power for the achievement gains made by teachers' future students.

The study, which was recently published in Labour Economics, found that subjective evaluations are comparable with and complementary to objective measures of teacher effectiveness taken from a teacher's first year in the classroom. The study's analysis drew on data on students and teachers in the public schools of New York City – specifically teachers of grades 3 to 8 in the school years 2003-04 through 2007-08, and their students' behavior, demographics, and achievement test scores in math and English.

Prof. Rockoff found evidence that teachers who receive better subjective evaluations of teaching ability prior to hire or in their first year of teaching also produce greater gains in achievement, on average, with their future students. Consistent with prior research, the results also support the idea that teachers who produce greater achievement gains in the first year of their careers also produce greater gains, on average, in future years with different students. More importantly, subjective evaluations present significant and meaningful information about a teacher's future success in raising student achievement. This finding is particularly noteworthy, since the variation in subjective evaluations may capture facets of teaching skill that are not captured by the study of standardized tests results.

Using the linked student–teacher data, the researchers objectively evaluated teachers' impacts on student test scores using an empirical Bayes' method. In terms of subjective evaluations, data came from New York City Teaching Fellows (TF), an alternative path to teaching certification taken by about a third of new teachers in New York City. Alongside this data, they also used data from New York City's "New Teacher Induction" program which spanned the school years 2004-2005 through 2006-2007. Under this centrally administered program, a group of trained, full-time mentors worked with new teachers over the course of their first year to improve their teaching skills and submitted ongoing evaluations of teachers' progress in mastering a detailed set of teaching standards. The study then proceeds to examine student achievement in the second year of teachers' careers; the researchers believe this provides a more rigorous test of whether objective and subjective performance metrics provide useful information for decisions such as teacher retention.

Consistent with prior research, first-year value-added estimates were significant predictors of student achievement in the teacher's second year. Furthermore, evaluations by mentors – and in particular variation in evaluations within mentors – bear a substantial positive relationship with student achievement in teachers' second years.

The study suggests that evaluation systems that incorporate subjective measures made by trained professionals and objective job performance data have significant potential to help address the problem of low teacher quality. However, the researchers warn that the application of standards can vary significantly across individuals responsible for making evaluations, and the implementation of any evaluation system should address this issue.

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....

Im Focus: Chemical reactions in the light of ultrashort X-ray pulses from free-electron lasers

Ultra-short, high-intensity X-ray flashes open the door to the foundations of chemical reactions. Free-electron lasers generate these kinds of pulses, but there is a catch: the pulses vary in duration and energy. An international research team has now presented a solution: Using a ring of 16 detectors and a circularly polarized laser beam, they can determine both factors with attosecond accuracy.

Free-electron lasers (FELs) generate extremely short and intense X-ray flashes. Researchers can use these flashes to resolve structures with diameters on the...
