en-usThe latest news on mathematics, math, math science, mathematical science and math technology. Study: German youth show weaker performance in math, reading and science compared to 2018Young people in Germany are less proficient in mathematics, reading and science as compared to 2018. This is revealed in a PISA study. About one-third of the 15-year-olds tested achieved only a very low level of proficiency in at least one of the three subjects. The results confirmed a downward trend already in evidence in the preceding PISA studies. The mathematics and reading scores of German students are only at OECD average levels. They remain above that level only in natural sciences.

An explosion of electrochemical events or "neuronal spikes" appears at various times during the action. These spikes in activity, otherwise known as action potentials, are electrical impulses that occur when neurons communicate with one another.

What if finding the solution to a problem took almost a century? For mathematicians who dabble in Ramsey theory, this is very much the case. In fact, little progress had been made in solving Ramsey problems since the 1930s.

New research from Renae Loh and others at Radboud University shows that in countries with better availability of information and communication technology (ICT) in schools, math performance benefits greatly. It further suggests that improving the ICT environment in schools can reduce inequality in education between countries. The paper is published in European Educational Research Journal today.

How teaching beliefs and professional knowledge specifically influence teaching approaches remained largely unclear. Also, most studies have focused on pre-service or elementary school teachers in the West. There is a need to know whether these conceptual frameworks can be applied and adapted to the Chinese teaching context at the secondary level.
