Виртуален час по математика

Author(s): Sevdalina Georgieva / Language(s): Bulgarian Issue: 3/2021

The challenge of conducting an electronic environment for remote mathematics education is a condition for finding effective methods, forms, approaches, and platforms for a successful learning process. One of the solutions for the implementation of a „virtual lesson“ in mathematics is the cloud environment of GeoGebra. The article discusses various aspects of the application of the online platform GeoGebra in mathematics education: creating interactive worksheets, virtual classrooms, online boards, tools for classroom management, monitoring, and evaluation of student achievement. The attitudes of mathematics teachers about the use of GeoGebra online applications in math lessons are researched and analyzed.

Generation of NO2 by Lead Nitrate Pyrolysis: Never do Modifications a Prima Vista

Author(s): Vlsdimir M. Petrusevski / Language(s): English Issue: 3/2021

Generation of nitrogen dioxide is a well-known demonstration/experiment, usually performed by pyrolysis of Pb(NO3)2. In order to prevent obstructing the glass tubes or the test-tube where NO2 is generated, one may safely use a homogenized mixture of lead(II) nitrate and dry sand. Aesthetically it is not quite appealing, so during the same lesson a colleague experimenter decided to change the standard approach and to use table salt (sodium chloride) instead of sand. However, the result of the experiment turned to be a flaw! This appears to be one more proof for the correctness of the general experimenter’s philosophy: never improvise if you do not know the outcome.

Computational analysis of the messenger RNA variants encoding two isoforms of the high-mobility group box 1 protein

Author(s): Luchezar Karagyozov,Jordana Todorova / Language(s): English Issue: 3/2021

High-mobility group box 1 protein (HMGB1) is a multifunctional nonhistone chromosomal protein. This widespread nuclear protein has a dual function-in the nucleus - it binds DNA and participates in practically all DNA-dependent processes. On the other hand, the protein plays an important role in the extracellular matrix as an “alarmin”, which interacts with certain receptors and stimulates biochemical pathways, associated with carcinogenesis and metastasis. HMGB1 is a critical damage-associated molecular pattern molecule, has been implicated in several inflammatory diseases and cancer types. This universality makes it an attractive target for innovative therapeutic strategies in the treatment of various diseases. The updated database for the HMGB1 gene, encoding the high-mobility group box 1 protein, was used for computational analysis of the annotated mRNA splice variants. Results showed that five of the splice variants encode an HMGB1 protein, containing 215 amino acid residues. However, two of the splice variants encode a shorter HMGB1 protein with 158 residues. Presently, the existence of a shorter HMGB1 protein is not registered in the protein databanks. This inconsistency is not yet resolved.

Professional Dispositions of Graduate Pre-service Mathematics Teachers among Three College of Teacher Education in Ethiopia

Author(s): Anteneh Tefera,Mulugeta Atnafu,Michael Kassa / Language(s): English Issue: 3/2021

The general objective of this study was to examine the professional disposition (attitude and self-efficacy) of pre-service teachers hold at the end of teacher education programs in terms of gender and modality. To do this, we used a quantitative research approach. The source of data was 3rd-year mathematics pre-service teachers who have graduated in the 2018/19 academic year. The study used self-reported questionnaires. Thus, 536 (309 male and 227 female) third-year pre-service mathematics teachers from the three sampled institutions (Kotebe metropolitan university, Hawassa college of teacher education, and Arba Minch college of teacher education) and trained under three modalities (generalist, specialist, or linear) have participated. The result showed that the ongoing teacher education program helps them to have a strong attitude and self-efficacy towards mathematics and mathematics teaching without gender difference. However, variations were observed in attitudes and self-efficacy across modalities. In general, it can be concluded that the teacher education program helps pre-service mathematics teachers to develop a strong attitude and self-efficacy towards mathematics and teaching mathematics. Therefore, it is recommended that further qualitative and detailed analysis should be conducted in order to find which part of the education system or educational inputs help pre-service mathematics teachers in colleges of teacher education to develop positive attitude and self-efficacy towards mathematics and teaching mathematics and should be shared to other universities and colleges.

Основни дидактически аспекти, свързани с прилагане на STEM технологията в обучението по природни науки

Author(s): Hristina Petrova / Language(s): Bulgarian Issue: 3/2021

STEM technology is an innovative educational technology. It refers to development of the students’ intellectual abilities, to constructive and cognitive-researching activity and to technical work. There are presented basic didactic aspects, connected with the applying of the STEM technology in Science education. The emphasis is put on practical tasks with problematic character. They allow 21st century competencies to be formed, such as creativity, communication skills, teamwork and critical thinking. Organization of the educational process, educational work forms and teacher’s new pedagogical role are also presented. Educational simulations and robots are looked at as didactic means of putting the STEM technology into practice while studying Science, in particular Physics.

Determination of Planck constant by LED

Author(s): Aleksander Petkov,Todor Mishonov,Matteo Andreoni,Emil Petkov,Albert Varonov,Iglika Dimitrova,Leonora Velkoska,Riste Popeski-Dimovski / Language(s): English Issue: 3/2021

This is the problem of the 8th International Experimental Physics Olympiad (EPO8). The task of the EPO8 is to determine Planck constant ħ=h/2pi using the given set-up with LED. If you have an idea how to do it, do it and send us the result; skip the reading of the detailed step by step instructions with increasing difficulties. We expect the participants to follow the suggested items – they are instructive for physics education in general. Only the reading of historical remarks given in the first section can be omitted during the Olympiad without loss of generality. Participants should try solving as much tasks as they can without paying attention to the age categories: give your best.

Образователна подкрепа на деца в резидентна грижа в условията на електронно обучение (Теоретични аспекти)

Author(s): Yuliana Kovachka / Language(s): Bulgarian Issue: 5/2021

The changed conditions for the educational process` implementation in a state of an emergency outside the school institution raise a number of questions regarding the educational opportunities for the children raised and brought up in residential services, i.e. Out of the biological family. The purpose of this study is to identify the resources, organization, and opportunities for effective e-learning for children and students raised in residential services and attending general kindergartens and schools. Precisely, these are specialized institutions – Social care homes for children deprived of parental care, and the so-called alternative residential care - family-type accommodation centers for disabled children and transitional housing. The selected target group differentiates between difficulties in the e-learning process, both for children and young people in residential care and for the professionals who support them and are not prepared for such a situation.

SWOT Analysis as a Research Method in Pedagogy

Author(s): Delyan Penchev / Language(s): English Issue: 5/2021

SWOT analysis is an approach traditionally applied in the field of strategic planning and strategic management. Its essence finds expression in the analysis of internal and external factors which can influence over development of the organization, a given managerial technique, etc. In view of this in present article are analyzed the possibilities for application of SWOT analysis in the field of pedagogy. This thesis is based on two basic points of view: first – in every scientific research the analysis of the received information and data is required and although that the said method is a specific type of analysis it has potential to be applied not only in the field of management and marketing but in others scientific spheres one of which can be pedagogy. Second – SWOT analysis can be treated as a scientific method and the results obtained through it – used for solving scientific tasks and purposes.
