More private schools improves all students’ outcomes

The growing proportion of compulsory school students attending private schools has led to higher test scores and grades in 9th grade.
This applies to students at both private schools and public schools. The effects persist in upper secondary school and higher education. This is shown in a new report.

In 1992 Sweden implemented a private-school reform. Students were given the opportunity, using vouchers, to choose between public and private schools. The number of private schools has continuously grown, and today more than 12 percent of Swedish compulsory school students attend private schools. All children can apply to these schools, and so-called cherry picking or cream skimming is forbidden.

Better test scores and longer education

The authors of the new report find that having a higher proportion of students in private schools improves students’ national test scores and their grades in 9th grade. If the share of students increases by 10 percentage points in a municipality, students’ knowledge increases by 3–4 percent in compulsory school. This effect persists when students attend upper secondary school. The proportion of students going on to higher education increases by two percentage points as a consequence of having more private schools, and the number of years of education attained at the age of 24 increases by nearly a month on average.

“It took 8–10 years after the implementation of the private school reform before we saw any positive effects. This is probably because it took some time for the private schools to become more than a marginal phenomenon in most municipalities,” says Mikael Lindahl.

Students in both public and private schools benefit
Students in both public and private schools profit; private school students are not favored.

“We don’t know whether it’s competition that makes schools improve, or whether new ideas are disseminated more widely. We have not found that different types of private schools generate different effects,” says Mikael Lindahl.

Furthermore, the cost of schooling does not rise when more students choose private schools.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
