Mer förskola gav bättre resultat i matte

Nationalekonomen Mattias Hallberg har undersökt hur tiden i förskolan påverkar skolresultaten i årskurs 9.
Varför valde du det här ämnet till din masteruppsats?
– Allt började med en diskussion jag hade med några kollegor. Några hade uppfattningen att förskolan är bra för att föräldrarna kan vara på jobbet, men inte spelar så stor roll för barnen. Medan de andra tyckte att barnen självklart lär sig massor av att gå i förskolan.

Pythagoras (570-495 BC), Euclid (~ 300 BC), Archimedes (287-212 BC)

Greek mathematicians had a significant influence in not only developing mathematical theory but also in embedding mathematics in the classical and modern curricula.
Apart from Pythagoras, who not only set up a school but has strict rules around behaviour and the basis of all knowledge in numbers, they were not learning theorists as such but their influence on what has and is still taught is substantial.

Math that feels good

Creating learning resources for blind students
Mathematics and science Braille textbooks are expensive and require an enormous effort to produce — until now. A team of researchers has developed a method for easily creating textbooks in Braille, with an initial focus on math textbooks.

Plato (428-348 BC) – Man of reason… but wary of fiction!

Plato’s Academy is thought by many to have been the first University, open to both men and women. He founded The Academy in 387 BC, a philosophical school that remained in use until AD 526, when it was finally closed down by the Emperor Justinian. Astonishingly, having run for 900 years, it rivals any current western university for longevity.

Above its door were the words Do not enter here unless you know geometry, as he saw mathematics as important training for the mind, along with the idea of clear hypotheses and proofs.

The wisdom of crowds: What smart cities can learn from a dead ox and live fish

In 1906, Francis Galton was at a country fair where attendees had the opportunity to guess the weight of a dead ox. Galton took the guesses of 787 fair-goers and found that the average guess was only one pound off of the correct weight — even when individual guesses were off base.

This concept, known as ”the wisdoms of crowds” or ”collective intelligence,” has been applied to many situations over the past century, from people estimating the number of jellybeans in a jar to predicting the winners of major sporting events — often with high rates of success.

Math test score gap between white and non-white students in Brazil due to complex factors

School test scores often show gaps in performance between white and non-white students. Understanding the complex reasons behind this can help reduce those gaps and promote social equality, explains Mary Paula Arends-Kuenning, associate professor of agricultural and consumer economics at the University of Illinois.
Arends-Kuenning is co-author of a study that analyzes math test scores for 9th-grade students in Brazil and breaks down the characteristics associated with performance gaps between different racial groups.
