Teenagers are becoming increasingly logical

12.05.2009
The capacity of teenagers for logic has been steadily increasing during the last 50 years. This is revealed by research at the University of Gothenburg, Sweden, that analyses changes over time in teenagers' intelligence.

A research project at the University of Gothenburg has been testing large groups of 13 year olds in Sweden since the early 1960s using the same intelligence test. The tests have taken place at approximately five year intervals and consist of an inductive-logic test, a verbal test and a spatial test.

Crucial factor

The most recent study, which was reported in the new issue of Journal of Swedish Educational Research, shows that today's teenagers are achieving demonstrably better results in the logic test than was the case fifty years ago. This is positive as logic is a crucial factor for achievement in mathematics. - With regard to pupils chances of assimilating maths teaching, there is thus nothing to indicate that the preconditions have deteriorated in recent decades, says Professor Allan Svensson at the Department of Education.

No inferior talents

The claim has recently been made that Swedish pupils' mathematical skills are declining when compared with other countries. This should therefore not be to do with inferior talents, but rather with factors such as course content, teaching methodologies, teaching media and teaching skills.

The development is not as positive in terms of teenagers' verbal capacity. After an increase during the 1960s, the test values start declining slowly before falling even more substantially from 1985.

Uncommon words

This is primarily due to the fact that the test is a vocabulary test and many of the words that are included are relatively uncommon in current Swedish. The analyses also reveal that it is precisely the old-fashioned words, such as "destitution" and "copious", that over time have become more difficult for teenagers, while words such as "separate" and "attack" have become easier for them to deal with.

- I would hazard to contend that the pupil's vocabulary is no smaller now that it was in the 1960s, but that it partially consists of other words. The prerequisites for today's pupils to assimilate teaching in Swedish are consequently not inferior, says Allan Svensson.

Girls perform better

Teenagers' spatial capacity, the so-called power of spatial imagination, is higher now than it was in the 1960s. This capacity has however diminished somewhat during recent decades, principally as a consequence of weaker attainment by boys. In its turn this has led to girls now performing better than boys in this test, while the situation was the reverse 50 years ago.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Now, a team of Penn Engineers has demonstrated a new material they call "nanocardboard," an ultrathin equivalent of corrugated paper cardboard. A square...

Im Focus: Nanorobots propel through the eye

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.

Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
