The Fiftieth Anniversary of the Institute of Mathematics and Informatics

In October 1997 we celebrate the fiftieth anniversary of the founding of the Institute for Mathematics and Informatics (IMI) of the Bulgarian Academy of Sciences (BAS).

Digitization of Old Mathematical Periodicals Published by the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences

The digitization practice for retro-converting of the mathematical periodicals, published by the Institute of Mathematics and Informatics, Bulgarian Academy of Sciences (IMI-BAS) and the followed benefits for long-term preserving and assuring open access to these materials is discussed in the article.

Faculty of Mathematics and Informatics, Sofia University

The Faculty of Mathematics and Informatics (FMI) of Sofia University “St. Kliment Ohridski” is briefly presented as an educational and research institution. The possible contribution of FMI to KT-DigiCULT-BG project is analyzed.

How to Select a Topic for a Project

Иванка Марашева-Делинова - В настоящата работа се разглежда избора на тема при разработване на проекти в непрофилирани по математика класове. Посочват се критерии за подбор на тема. Предлагат се примерни теми и източници за разработка, съобразени с възрастовите и индивидуални особености на учениците, както и техните общи и индивидуални интереси.

Evaluating the Quality of Student Web Design Projects

Иван Шотлеков, Асен Рахнев - В настоящата работа се представя набор от критерии за оценяване на качеството на студентски проекти за уеб дизайн. Критериите са подходящи за разработване, самооценяване, колегиално оценяване и оценка на уеб сайтове, проектирани от студенти. Тази оценъчна скала е апробирана по време на курс “Английски език в информационните технологии”, проведен със студенти от първи курс по информатика във Факултета по математика и информатика на Пловдивски университет “Паисий Хилендарски”. Тя помага на студентите при разработването на мултидисциплинарен проект за уеб дизайн да придобият не само технически умения, свързани с проектирането на качествени уеб сайтове, но и някои процесуални умения, които ще им бъдат необходими в реалната практика.

A Problem on Infinite Series: Difficult or Easy?

Петра Стайнова - Разглежда се един стандартен въпрос за намиране на сумата на реда на Лайбниц. Дават се две различни решения, използващи знания от различен материал. След преформулиране на проблема се оказва, че решението му е възможно с директно използване само на основни понятия. По този начин е показано, че въз основа на една и съща базисна математическа идея могат да бъдат формулирани задачи, допускащи както стандартни, така и нестандартни решения.

Въвеждане на рекурсията чрез абстракция и редици от задачи

Pavel Azalov - Recursion is a powerful technique for producing simple algorithms. It is a main topics in almost every introductory programming course. However, educators often refer to difficulties in learning recursion, and suggest methods for teaching recursion. This paper offers a possible solutions to the problem by (1) expressing the recursive definitions through base operations, which have been predefined as a set of base functions and (2) practising recursion by solving sequences of problems. The base operations are specific for each sequence of problems, resulting in a smooth transitions from recursive definitions to recursive functions. Base functions hide the particularities of the concrete programming language and allows the students to focus solely on the formulation of recursive definitions.

Оптимизация на учителския състав в училище

Silvia Baeva - In the Ministry of Education and Science’s system it has been talked about optimization of the school network; this optimization can be carried out in different directions and be supported by laws. An important aspect in the optimization of the school network is to reduce costs and increase overall efficiency in each school. We will formulate this aspect as a problem of the multicriteria decisions making and by appropriate numbers of methods and criteria it can be transformed to the problem of unicriterion optimization. This problem is separated into two stages: 1-th stage – determining the minimum number of classes in a school under certain statutory provisions for the size of each of them; 2-th stage – the appointment of a minimum number of teachers and achievement of maximal effectiveness of teaching and acquiring of knowledge and skills by students according to certain statutory provisions for teachers’ annual norms of subjects and number of hours in a particular subject area and the salaries of teachers. The achievement of maximum overall efficiency is a priority in all schools.

Едно обобщение на Наполеоновите триъгълници

Dimitar Belev, Vasilka Ignatova-Beleva - We present a generalization of the Napoleon triangles and investigate some of their properties.

Един начин за преговор на формулите по тригонометрия в средното училище

Kliment Vasilev - The trigonometry formulas are given in the form of mathematical problems. Some of these problems are solved, and it is shown how the others can be solved with the help of adequate guidance that includes the previous problems. This method is suitable for revision in the secondary school, as well as for preparation for school-leaving exams and matriculation.

Анализ и влияние на приема с матура в кандидат-студентската кампания 2009 във факултета по математика и информатика на су “св. Кл. Охридски”

Evgenia Velikova-Bandova, Denitsa Grigorova, Maroussia Slavtchova-Bojkova - The aim of this work is to evaluate the quality of the preliminary exam of candidate students in Mathematics held on April 12, 2009. We also sought to highlight advantages and disadvantages of new approaches for application and admission to the Faculty of Mathematics and Informatics (FMI) at the “St. Kl. Ohridski” Sofia University (SU) in 2009. In this connection, the data by the candidate students’ examinations and assessments of matriculation were analyzed, a comparative analysis of these assessments were done and a relationship between them has been sought.

Модел за изследване на креативното мислене и действие на ученици

Veselina Valkanova, Stanimir Stoyanov, Hussein Zedan, Ivan Popchev - In the paper a theoretical model for investigation of creative thinking and action of student is presented. The model extends the formal system called Creativity Map. Furthermore, an experiment for applying this model in the secondary school is explained. Although the experiment will be implemented during the mathematics lessons, the theoretical model can be applied in different subjects.

За извънкласните форми на обучение по математика

Stojanka Valcheva, Vladimir Todorov - In the present talk we discuss some problems that arise out of the limiting the time designed for teaching Mathematics in the secondary school in Bulgaria.

Международно отборно математическо състезание “Галилей”

Vladimir Georgiev, Donka Darakchieva, Stoyan Kapralov - The 2009 edition of the International Mathematics Team Competition “Galilei” is presented.
