A broad view of mathematics education takes it as the study of how people learn and do mathematics. Starting with this view, the actual and potential relationships of mathematics education as are search discipline to mathematics as a field of knowledge and activity and to the mathematicians carrying out that activity are analyzed. This leads to the picture of a gulf between the two scientific communities which are based in different cultures of thinking and research. A (meta-)study of mathematics and all its facets termed here mathematicology is proposed. It could serve as common ground for cooperative studies by mathematicians and mathematics educators. Thereby the gulf will not necessarily become narrower but abridge over the differences and mutual misunderstandings could be built.  相似文献

Abstract

The purpose of this investigation is to examine whether or not the physical fitness (max. oxygen intake measured on cycle ergometer) of school children interacts with their intelligence and school achievement. If there is any interaction, will this change from grade 4 to 7? Another question is whether or not the socioeco‐nomic status of the parents is correlated with the children's development of physical fitness. The results show that there is a significant negative relationship between physical fitness (max. oxygen intake) and intelligence in grades 4 and 7, and that this relationship is significantly less pronounced in grade 7 than in grade 4: while the bright children have a favourable development the dull have an unfavourable development of physical fitness from ages 10 to 14. No relationship was found between physical fitness and school achievement in grades 4 and 7. Both in grades 4 and 7 there was found a significant relationship between the socioeconomic status of the parents and the children's physical fitness. No change in this relationship was found from ages 10 to 14.  相似文献

The coloured eye glow of animals, seen at night when their eyes are caught in a strong light, is a matter of common experience. It is caused by a reflecting layer known as the tapetum lucidum. A similar eye glow is seen in butterflies and apparently serves to enhance vision by increasing contrast and reducing glare.  相似文献
