Anxiety in Science Education [In Bulgarian]
Резюме. The article discusses the importance of emotion knowledge and especially the knowledge of anxiety in science education and mathematics for improvement of studentsâ€™ achievements. A modified version of SAS (Science anxiety Scale), adapted for use in Bulgarian, was employed for assessment of studentsâ€™ anxiety in the teaching of biology and health education. With the aid of this scale, examination anxiety of eight and nine grade students of the general secondary school and of nine grade students in a technical school of construction as well as anxiety of nine-twelve grades biology students in a secondary language school (compulsory and elective courses) was assessed and evaluated. The sample of students was 270. Biology examination anxiety scores were significantly reduced after immediate biology achievement tests and correlated with delayed achievement tests. The results showed dependence of anxiety on achievement test itemsâ€™ difficulty, achievement test attitudes, and individual physical, psychological and social studentsâ€™ characteristics as well as on studentsâ€™ aims and goals. Anxiety assessment simultaneously with academic achievement assessment and evaluation proved the importance of individual approach to studentâ€™s development of emotional intelligence for his/her personal progress in biology learning. Examination anxiety was reduced with the aid of interactive teaching strategies and techniques, with preliminary determination of the reliability and validity of tests as well as with assessment and evaluation of test itemsâ€™ difficulty and discriminative ability. Biology examination anxiety is a distinct type of science anxiety.

Higher Education Perspectives for an Exciting Educational Experience – Part V: An Indian Context
Резюме. The universities and the higher educational institutions, being embodiment of their strengths and collective aspirations, help reshape the idea of developed India. The diversity of the higher education-trained workforce is of concern, as the economy needs scientists and innovators who can work with diverse collaborators in an increasingly open marketplace. Best practices for developing national interest, education revolution, change challenges, and random perspectives are presented. The challenge of changing higher education landscape is huge, and a significant shift in mindset and a disciplined lifestyle are necessary to have sufficient number of high quality skilled workers available on a consistent basis in the decades to come. India can emerge as a global platform for higher education and high quality research with a policy environment which is predictable, transparent and fair. We have to make concerted efforts and investment to achieve progress in certain key areas of education, energy, science and technology. The new developments must make existing education process and delivery systems more efficient and effective. The fundamental reform agenda for higher education will be to improve the quality and competitiveness of higher education and research, and empower individuals and society committed to the progress of the nation.

Chemistry Research in the University of Sofia: The First Hundred Years [In Bulgarian]
Резюме. The history of the scientific research in chemistry carried out through a century at the University of Sofia is briefly presented. Three arbitrary periods are distinguished: 1889 â€“ beginning of 1920â€™s, research in classical chemistry of 19th century; 1920â€™s â€“ end of 1950â€™s, radical renovation which led to modern scientific research on European level in 1940â€™s; beginning 1960â€™s â€“ end of 1980â€™s, significant extensive development including new research directions and themes. The directors of research, professors and heads of departments are presented.
