We find a necessary and sufficient condition for a normal decomposition of the group of normed units in a commutative group ring (of prime characteristic) into certain its subgroups. This extends a recent assertion of ours in (Vladikavkaz Math. J., 2007). We also give some new proofs of own recent results published in (Miskolc Math. Notes,

The Effectiveness of the Enrichment Program in Sixth Grade Math and Science Classes A.Navidi, Ph.D. To improve students' learning in math and science enrichment programs have been introduced, yet their effectiveness has never been assessed. To this end, a large sample of administrators, teachers, and students were questioned and tested, while 46 class sessions were also observed. Over 400...

In recent years, we have seen the development of new TEX engines, X E TEX and LuaTEX, adopting OpenType font technology for providing Unicode typesetting support. While there are already plenty of OpenType text fonts available, both from the TEX community and from commercial font suppliers, there is little support for OpenType math fonts so far. Ironically, it was left to Microsoft to develop a...

Math anxiety indicates psychologically a negative mind-set towards solving mathematical problems which impacts on students‟ learning practices and outcomes. In looking more closely at why a remarkable no of students may be struggling for improvement in mathematics in comparison to other subjects, it is timely to consider, the math anxiety factor. This literature review looks at the concept of m...

Mathematical content is a valuable information source and retrieving this content has become an important issue. This paper compares two searching strategies for math expressions: presentation-based and content-based approaches. Presentation-based search uses state-ofthe-art math search system while content-based search uses semantic enrichment of math expressions to convert math expressions in...
