Относно задължителността на предучилищното образование – резултати от едно изследване

Author(s): Margarita Koleva,Blaga Dzhorova,Eva Zhecheva / Language(s): Bulgarian Issue: 8/2021

The authors present the results of a survey revealing the specificity of public claims regarding compulsory preschool education in the institution of kindergarten and specifically - the compulsory inclusion of 4-year-olds in it. Agreements and disagreements, polar opinions and alternative proposals for upbringing and educating the preschool child are an indicator of the lack of sustainable and irrefutable "evidence" of the importance of "compulsory" preschool education, as well as of the qualities of the socio-pedagogical environment in the children group and kindergarten. The paper is the second part of the authors' research on issues related to compulsory preschool education for children.

Към нови измерения на екологичното образование в СУ „П. Кр. Яворов“ – първото екоучилище във Варна и региона

Author(s): Margarita Marinova,Bisera Zhelyazkova / Language(s): Bulgarian Issue: 6/2021

Today we all live in an extremely dynamic world which provokes a variety of challenges related not only to health but also to education and social isolation. It appears that many young people are motivated and ambitious to shape their own future gaining experience and confidence during the school years. Many of their ideas have a creative and rational potential which triggers socially useful initiatives and projects on regional, national or international level. Participation in eco projects, volunteering and supporting social causes combines studying and practical activities and, thus, raises the quality of education and breaks its traditional character. And when innovation is also included, the result is predetermined and winning. Using an integrated system for ecological management, “Peyo Yavorov” Secondary School has encouraged students, teachers and parents to participate in eco initiatives for more than 20 years. This enriches their knowledge and improves the environment. Focusing on the ecological education ensures better understanding of the environmental problems with their local and global impact. Different approaches are used for developing key competences which creates later an active, healthy and environmental-friendly behavior. Activities in the eco field have proved to be effective as means of raising sensitivity and responsibility aiming at the change of one’s attitude – towards themselves, the others and the environment.

Свобода и отговорност на учителя и учениците при работа в малки групи

Author(s): Rozalina Dimitrova / Language(s): Bulgarian Issue: 6/2021

In modern school, when learning a foreign language, an approach which is used more and more often is students work in small groups. If we estimate the efforts which students put in working in a group in order to achieve a common result, then all the students’ motivation is considerably higher. Working in small groups during Russian language classes creates a very good opportunity for communication, enables the development of students’ speaking ability which is very important in learning foreign language. Working in small groups develops students’ communication skills, creates their personal qualities, helps them realize their social role in society. The teacher’s role changes, too. The teacher only directs the work, partly helps, corrects and supports the creative searching.

Study of Compositions for Selective Water Isolation in Gas Wells

Author(s): Sudad Al-Obaidi,Miel Hofmann,V. Smirnov,F. Khalaf,H. Alwan / Language(s): English Issue: 6/2021

A hydrophobic composition containing water repellents and highly volatile solvents is shown in this tudy to isolate water from the bottom hole formation zone of gas wells and reduce as much as possible the saturation of pore spaces with water. During injection, this composition shows selectivity and mostly penetrates water-saturated porous media. The study shows that the injection of such composition into porous media has a high water-insulating effect, reducing the water permeability of water-saturated porous media by 35 times with a degree of water isolation of 97%. Moreover, while injecting, it has selective action, mainly penetrating water-saturated media rather than gas-saturated media. As a result of injecting 0.91 to 0.99 pore volumes (pv) of the composition, the Qwater/Qgas ratio reaches 5.22 to 5.26, indicating high selectivity.

On the Sound, Produced by a Coin, Rolling in a Balloon

Author(s): Denitsa Vasileva / Language(s): English Issue: 6/2021

Balloons may be a thing children love playing with, but they also have different interesting physical properties such as the sound that is produced when something is put inside a balloon. The phenomenon of interest of this article is the one of gently rolling a coin in a balloon and exploration of the sound produced by this movement. It turns out that when a coin with edges is put in a balloon and is being rolled a buzzing sound is produced which varies in frequencies depending on the count of edges of the coin. This can be observed in non-laboratory conditions. Not many experiments have been conducted to explore this phenomenon.

A Possible Contribution of Live Electronics to Modern Education / O posibilă contribuție a aplicațiilor electronice live la educația modernă

Author(s): Mihai Popean / Language(s): English,Romanian Issue: 1/2021

Musical improvisation is as much a form of art as it is a form of education with great potential for transfer. Although associated usually with jazz music, improvisation has a long and unbroken history that can be traced throughout the entire music history. The classically-trained students do not receive education in improvisation, it is not part of the classical music curriculum, the educators themselves do not have such training and are not comfortable improvising and therefore teaching it. However, students can greatly benefit from this type of training by greatly enhancing their technique and performing skills and also by developing a set of other important skills such as creativity, calculated risk-taking, flexibility of mind, capacity to notice opportunities, greater awareness of their environment, intra- and interpersonal skills, enhanced communication abilities and more. One solution that would address teachers’ lack of improvisational skills and students’ need for such educational opportunity is for educators to learn basic visual programming in order to create applications for improvisation that involve live electronics and deploy them in classroom or other educational situations.

Collaborative DIY music production practices in conservatoire settings: findings from a pilot distance teaching-learning project /Metode de producție muzicală colaborativă DIY în cadrul școlilor de muzică: rezultate ale unui proiect pilot de predare-

Author(s): Yannis Mygdanis,May Kokkidou / Language(s): English,Romanian Issue: 2/2021

In the last decades, the vast development of emerging technologies has transformed the ways people engage with music, expanding the affordances of music expression, creation, learning, and education. Music production software allows artists to create songs collaboratively in digital contexts, not necessarily being in physical contact. Likewise, many young people produce songs alone or with peers, constructing musical experiences through informal kinds of learning. Although several studies have focused on integrating technological-based activities in school music education, the research interest in conservatoire education is limited. The COVID-19 pandemic crisis and the need for an urgent shift to online educational environments revealed numerous problems concerning the use of technology. Both teachers and students faced difficulties to operate and effectively continue the studio lessons online. Some recognized the situation as a dead-end for conservatoire education, while others perceived it as a prompt for innovative and creative solutions. The present article discusses the findings of a pilot distance musictechnological project with adolescents in conservatoire education during the COVID-19 pandemic. The primary aim was to investigate students’ musical-technological experiences, the knowledge and skills they acquired, as well as the development of their musical creativity through collaborative DIY music production practices. In particular, our purpose was to develop a more nuanced understanding of how the students experienced their work and their learning using DAWs (Bandlab). The results support the view that merging traditional and online teaching-learning procedures in a hybrid approach can open new pathways in music education

Innovative Proposals for Database Storage and Management

Author(s): Yulian Petkov,Alexandre Chikalanov / Language(s): English Issue: 1/2022

At present, the problem of storing large data sets as a source of artificial intelligence acquires a geopolitical and strategic character. The most well-known and used type of databases so far are the relational (SQL databases) and nonrelational (NoSQL databases. The both approaches have some principle problems, which are described below. That publication presents two original approaches to overcoming some of these shortcomings. First one is Object-oriented model for storing data in a relational database. The second is Storage of non-relational data in a relational database according to previously freely created by the user models. Presented models were used as base for software development of more than ten middle and large size national and European scientific and industrial projects.

Distance learning: Homemade colloidal silver

Author(s): Jorge G. Ibanez,Ana Sofia Covarrubias-Montero / Language(s): English Issue: 1/2022

To continue the experimental education of Chemical Engineering students during the SARS-Covid 19 pandemic, our school opted for assembling laboratory kits for each one of them and sending them by courier service to their homes. This arose much interest and was particularly successful in an Electrochemistry and Corrosion elective course, because up to 25 experiments were performed in each of the Fall 2020 and Spring 2021 semesters. By having their kits at home, students were also able to design experiments on their own. One such experiment –the preparation of a colloidal silver solution– only required readily available kit materials and some other home and kitchen items to produce an easily observable Ag colloidal solution. Lower classes (e.g., General Chemistry, High School Chemistry) should be able to reproduce this experiment as well. The entire procedure can be completed in 1 h.
