Published in the July issue of the Econometrics Journal, the study found that although assigning more homework tends to have a larger and more significant impact on mathematics test scores for high- and low-achievers, it is less effective for average achievers.
“We found that if a teacher has a high-achieving group of students, pushing them harder by giving them more homework could be beneficial,” Henderson said. “Similarly, if a teacher has a low-ability class, assigning more homework may help since they may not have been pushed hard enough. But for the average-achieving classes, who may have been given too much homework in an attempt to equate them with the high-achieving classes, educators could be better served by using other methods to improve student achievement. Given these students’ abilities and time constraints, learning by doing may be a more effective tool for improvement.”
According to co-author Ozkan Eren, assistant professor of economics at the University of Nevada, the study examined an area previously unexplored, namely the connection between test scores and extra homework.
“There has been an extensive amount of research examining the influences of students’ achievement, but it has been primarily focused on financial inputs such as class size or teachers’ credentials,” Eren said. “Our study examined the affect that additional homework has on test scores.”
While past studies suggest that nearly all students benefit from being assigned more homework, Henderson and Eren discovered that only about 40 percent of the students surveyed would significantly benefit from an additional hour of homework each night.
The findings should be of particular interest to schools who have responded to the increased pressures to pass state-mandated tests by forcing students to hit the books even harder, Henderson said.
“This does not mean that homework is unimportant for average achievers,” he said. “But it does mean that this population may also benefit from other activities such as sports, art or music, rather than additional hours of math homework.”So what can teachers take away from the study? Henderson points out that every student is unique and while umbrella policies may benefit some, they generally cannot be applied to all. “In my own personal experience, I see that each semester requires a different approach,” Henderson said. “This is even true when I teach the same course twice in a semester. Different times of the day or lengths of classes require different methods -- just as different quality students require different approaches.”
“Teachers should consider quality over quantity when it comes to homework assignments,” he said. “In the end it should be up to the individual teacher to decide how to motivate and educate his or her students. One of the most beautiful things about America to me is the creativity that we instill in our primary/secondary schools. I know that we lag behind many countries in test scores, but I am willing to accept that, assuming that we also produce creative, enthusiastic students.”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.
