Teacher Knowledge is Key to Successful Computer Use in Schools

University of Gothenburg researchers are studying One to One Computing and how its methods and outcomes compare to traditional classrooms.

The educational effects of the One to One Computing initiative – a computer for every student – are under the microscope in Sweden.

University of Gothenburg researchers are assessing the ways educational processes change due to access to information and communication technology (ICT).

The researchers are specifically interested in learning how traditional classroom fare differs from what happens in classrooms where the One to One initiative has been put into practice.

ICT should be seen as a tool that is an integral part of subject matter knowledge – for example, knowledge in mathematics is not only knowledge of abstract mathematical concepts but also how to solve problems using mathematics software for modeling, simulation and visualization. ICT is more and more becoming a natural part of teaching and learning, like paper and pencils.”

— Professor Berner Lindström, The University of Gothenburg, Sweden

The effects of the One to One initiative, according to Lindström, depend upon teachers’ knowledge of computer technologies, including “…advanced subject matter knowledge; knowledge of how to use ICT for pedagogical purposes; knowledge and skills of how personally to use ICT; knowledge about ICT and societal changes; and furthermore, knowledge of how to work with ICT and school development on the classroom level.”

Choreography for Electrons: A Two-Step Closer to Quantum Computing

In a project that started ten years ago, an international team of researchers has attained a “100-fold increase” in the capacity to control electron spin within a solid material. Researchers Stephen Lyon and Alexei Tyryshkin are now able to control the spins of billions of electrons for as much as 10 seconds, which far exceeds previous attempts.

The achievement is considered to be an important milestone in the race toward developing ultrafast quantum computers. Those involved with the project underscored that this is only a step toward a working computer.

How might scientists and others make use of such computers? It’s hard to say at this stage, but some believe a quantum computer could help with factoring massive numbers, breaking codes, or even simulating molecular behavior.
