My Experience in Reviewing of Theses and Other Papers in the Field of Science Education<\/h3>\n

Abstract. <\/strong> According to the Bulgarian Act of Scientific Degrees and Scientific Ranks (1972) two referees evaluate the dissertations and other academic papers of the candidates for the scientific degree \u2018doctor\u2019 (PhD); these referees are three when the candidate makes claim to the scientific degree \u2018doctor of science\u2019 (DSc). When one applies for the scientific rank \u2018docent\u2019 (Associate Professor) the referees are two again, but when the application is for the highest scientific rank \u2018professor\u2019 (Professor), the evaluation of the candidate\u2019s scientific achievements is made by three reviewers. The author of the present article shares his experience in the participation in these evaluation procedures. Mainly the area of science education is under his attention.

Secondary Analogy between Chemical Elements<\/h3>\n

Abstract. <\/strong> Primary intra group analogy is the base of periodic teaching and is explicitly indicated in most of the periodic tables. The same maximum number of valence electrons having similar valence electron configuration of elements connects them with primary analogy. In addition to this, there occurs secondary inter group analogy between chemical elements in the periodic table. This analogy combines elements of groups-A, B and C with same number of valence electrons in a form of family. In general, these families exhibit similarities only in their maximum oxidation states. This article covers secondary analogy of the elements.
Keywords: chemical elements, periodic table, primary analogy, secondary analogy

Chemical Experiments in the Chemistry and Environment Electronic Textbooks for 9 and 10 Compulsory Grades<\/h3>\n

Abstract. <\/strong> The selection of chemical experiments in the Chemistry and Environment electronic textbooks for compulsory 9th and 10th grades of the Bulgarian secondary school is considered in the present paper. The experiments have been chosen to meet the requirements of the curricula. The didactic requirements for the chemical experiments are carefully taken into account. The special rules of preparation of electronic materials are fulfilled. The selected experiments have been broadcasted as short videos and have been included in the respective lessons. Thus experiments which are hard to perform in the school laboratory because of the luck of enough time have been successfully demonstrated. Such video tools facilitate teachers in their school activity. They could be used by the students in their self-learning.

An Alternative Synthesis of Calcium Dobesilate, A Simple Venous Insufficiency Drug, Suitable for Use in Medical or Organic Chemistry Practical Courses<\/h3>\n

Abstract. <\/strong> Calcium dobesilate, calcium 2,5-dihydroxybenzensulfonate, a commonly used venous insufficiency and diabetic retinopathy drug, is usually synthetised according to original patent of Esteve-Subirana [6] by a \u201credox substitution\u201d of 1,4-benzoquinone with calcium hydrogensulfite. This paper describes an alternative synthesis of this drug by sulfonation of hydroquinone with following neutralization of 2,5-dihydroxybenzenesulfonic acid with calcium carbonate. This preparative way is suitable also for use in chemical or pharmaceutical education, e.g. in practical exercises in Medicinal chemistry or in Organic chemistry.<\/p>\n

Selective Transport of Silver(I) Ion across a Polymer Membrane Containing 18S6 Ionophor<\/h3>\n

Abstract. <\/strong> The selective polymer membrane transport of Ag(I) ion from an aqueous solution containing seven metal cations, Co(II), Ni(II), Cu(II), Zn(II), Ag(II), Cd(II) and Pb(II), was studied .The source phase was 0.01M to each of the above-mentioned cations at pH 5.0 (CH3COOH\/CH3COONa). The receiving phase was buffered at pH 3.0 (HCOOH\/HCOONa). The selective silver(I) ion transport occurred (J = 4.14 x 10-6 mol\/h at 25oC) from source phase across the polymer membrane containing 18S6 as the ionophore into the receiving phase. The highly transport selectivity was observed for Ag(I) ion.

Electronic Course on the Methods and Tools of the Teaching Chemical Experiment<\/h3>\n

Abstract. <\/strong> The aim of this paper is to launch an electronic course (e-course) on the methods and tools of the teaching chemical experiment. This course is intended for the chemistry students of the Department of Chemistry at the University of Sofia \u201cSt. Kliment Ohridski\u201d. The purpose of that course, both traditional and electronic, is to develop the ability of the prospective teachers to carry out chemical experiments in their future school practice. Analyzing the special features of the traditional course, the need for implementation of computer-aided teaching is argued. The e-course is split in two sections – informational and practical. The informational part consists of theory, experiments and methods. Assignments and proper means of electronic communication between students and the teacher are presented in the practical part. This e-course is tested in practice.
Keywords: e-learning, e-course, computer-assisted teaching, chemical experiment

A Book Written with Love and Respect (E. Golovinsky, 2008)<\/h3>\n

Abstract. <\/strong> In his book the author tells memories about his childhood, school and student years and describes his work as a researcher, university lecturer and promoter of science. He shares impressions from his teachers at school and university, tells about his relations with friends, classmates, fellow students and colleagues. E. Golovinsky shares his experience as a tutor of younger scientists and scientific teams. He remembers his own tutors who left their personal contribution in our national science and education. In the book the reader will find exciting episodes concerning author\u2019s meetings with interesting persons \u2013 scientists, men of art and culture. E. Golovinsky tells about important events fro the history of our country and points out his contacts with the science from other countries \u2013 Germany, Russia, France and Austria. He also describes some of his participations in international scientific meetings. The author shares his views about the education, the organization and role of the scientific investigations as well as about some cultural processes in our country and abroad.<\/p>\n

Educational System in Japan (A. Ivanova, 2008)<\/h3>\n

Abstract. <\/strong> The contents of the book comprises of 243 pages, structured in: preface, four chapters, 17 appendixes, glossary and bibliography, with 126 quoted titles. In structural and idea-conveying aspect, the book meets the requirements of a book of a monographic character. As a general characteristic of this monograph I would like to mention some of its obvious merits: logically ordered and systematically presented material; exceptionally clear and exact thought; thorough a comprehend give research of each subtitle which suggests hard and diligent work with many primary sources. The book is read at one go. It is difficult to say which part dominates the others, as each chapter is fully detailed and covers the topic given in the title. As a biologist, the author supports the factual material, the analysis presented and the conclusions drawn through a number of concrete examples of curriculums, text books and different kinds of systems of testing of knowledge in the field of biology. The monograph becomes completed with its 17 appendixes and the glossary of the Japanese terms, as replacing of the most of these terms with Bulgarian translations would be inappropriate or even incorrect. In this respect I would like to put an emphasis on the fact that the author is really well-oriented in the Japanese history and in the Japanese terminology with its meanings.<\/p>\n
