Abstract
Many students have more difficulty in solving word problems than numerical problems in school mathematics. It is because solving word problems requires linguistic knowledge as well as mathematical knowledge. Recently neuroimaging technique attempts to investigate areas of human brain for mathematical and linguistic thinking. This research aimed at analyzing the relative power spectrum of EEG activities and the degree of cognitive load of 12 adults during performing numerical and word problems. The results showed the theta band tended to more increase when solving word problems than numerical problems, the alpha band tended to increase from solving numerical problems to word problems, the beta band tended to be activated in more brain areas when solving word problems than numerical problems, and the gamma band tended to increase in the frontal area for both numerical and word problems. The EEG analysis revealed that the activation pattern of the human brain for numerical problems was different from the activation pattern for word problems. This neurological approach can be used to find the solution for difficulties of learning mathematics.
