The objective of this work is to study the magic squares, to address historical aspects related to their emergence and their use by artists throughout the centuries, as well as to analyze the magic squares in the resolution of linear systems and in the language of the vector spaces of matrices. As a result, one can obtain another motivation for the study of matrices and linear systems, both in High School and Higher Education.

The dynamics of several demographic indicators of Russia - child and teenage cohorts in 1970-2000, life expectancy in 1995-2000, migration flows among federal districts in the period between two censuses of 1989 and 2002 - are considered in the article. The author puts forward the hypothesis about the influence of these indicators on the level of education in narrow and broad senses - in educational institutions and the society as a whole. He estimates the perspectives of regional higher educational institutions under conditions of absence of plan distribution of graduates and the double cyclical fall in the number of high school graduates. The agenda for the development of a two-stage system of higher education corresponding with international integration processes is formulated.

AbstractThe present paper appraises a standardized test, the entrance exam of Iranian universities, known as “Konkur” that is administered annually as a means of gaining admission to higher education in Iran. This norm-referenced test is administered for students majoring in mathematics, experimental sciences, and humanities whose scores along their weighted GPAs in the last 3 years of high school are used as indicators of students’ rank. Based on the rank achieved, they would find the opportunity to select the highly regarded university for their education. Due to the importance of such a high-stake test which may bring about social and long-time consequences for the participants, the present paper tries to evaluate the test and its psychometrics aspects. It is ostensible that the exam provides a limited  situation for measuring the participants “knowledge of language” rather than their “knowledge about language.” Therefore, the dimensionality and validity of the test are debatable. Thus, the present review tries to characterize Konkur examination and discusses the rooms for untouched aspects for the betterment of its quality.
