POSSIBLE USE OF LASERS FOR CLEAVAGE OF PHENOLS TILL BASE SUBSTANCES (REVIEW)
Get PDFThe purpose of this review article is to explain the hazards of phenol and phenol compounds to human health and the environment. To describe where and how phenol and its compounds occur, especially in industrial effluents. To study the possibility of using laser technologies for phenol cleavage, as well as for the treatment of industrial wastewater from phenol compounds. Removal of phenol and its compounds using biological wastewater treatment process is widely used worldwide. This method is cost-effective and environmentally friendly. On the other hand, exceeding the tolerable phenol concentration, which is individual for each biological treatment plant, may result in severe intoxication and lead to death of activated sludge system. Thus, the biological treatment process of industrial wastewater is halted until the phenol concentration is reduced to an acceptable level and the microorganisms have time to recover. Such a procedure can be time consuming and unpredictable due to the susceptibility of microorganisms to changing conditions. Based on this, sources of literature have been studied that could help to understand which laser equipment can be used to cleave a phenolic compound or benzene ring to simpler compounds

STUDENTS’ DEPTH OF COGNITIVE PERFORMANCE ON SECONDARY SCHOOL STATE MATHEMATICS TESTS
Get PDFLatvia began curriculum reform implementation in 2020. Not only has the learning content changed, but students are also now able to choose from one of three levels to study mathematics in secondary school. This requires new exams at the end of each of these courses. The aim of this study is to investigate student performance and to what extent students can use higher cognitive skills on the new exams. Results were analyzed using Classical Test Theory and Item Response Theory. Comparing the results of the new exams using Wright maps shows a trend that, although there are flaws, they are more representative of the relevant population than the previous exam. A group of experts determined the level of cognition for each of the tasks and analyzed students\u27 performance. The results show that there are tasks where students can demonstrate the highest level of cognitive abilities. However, such tasks are relatively few, and they are mathematical rather than problems in a real context. Performance analysis shows that students have difficulty expressing their thoughts and this is one of the reasons why only a small number of students solve challenging problem
DETERMINING THE KNOWLEDGE LEVEL OF PUPILS IN THE INFORMATION SYSTEM OF "SMART SCHOOL"
Get PDFAt a time when current information technologies are rapidly developing, the effectiveness of the quality of education in secondary schools, the transparency of the teacher evaluation system and the analysis of several other indicators with the help of artificial intelligence are the urgent issues of the day. In this method of analysis, initially the value is entered by school experts. This value consists of a pupil in a certain category among pupils and his grades. The term category refers to various criteria, such as pupils with different levels of mental activity, pupils who are learning poorly, who are missing a lot of lessons, and the level of learning is high or low within the specified subjects or topics. The "Smart School" information system forms arrays consisting of the number of grades and grades of pupils according to the criteria entered by experts, and has the ability to sort the values that are similar to the entered value. The solution to the problem posed in this article is explained mathematically and practically. Based on the proposed mathematical models, the business process was modeled, a business process software product was developed, and statistical data was obtained
THE ROLE OF SELF-EFFICACY IN PHYSICAL ACTIVITY IN STUDENTS: A LITERATURE REVIEW
Get PDFPhysical activity among adults and adolescents do not meet the recommendations of WHO. Many studies focus on investigation of physical activity in students and the role of self-efficacy as important factor in predicting physical activity behaviour. Aim of the study was to determine the role of self-efficacy in physical activity in students. A literature review has been conducted to determine the self-efficacy measurements in physical activity studies and to determine factors related to self-efficacy and physical activity. Through search in the PubMed database 206 records were identified and 24 articles were included in further analysis. Thirteen studies used the General Self-Efficacy Scale [GSES] to measure self-efficacy level. Two studies considered The Exercise Self-Efficacy scale [ESES] focusing specifically on physical activity. Other studies considered different self-efficacy measurement tools including separate questions about physical activity self-efficacy as part of the questionnaire or survey used in the study. One study focused on emotional self-efficacy measures. Other factors investigated in relation to self-efficacy and physical activity were health beliefs, anxiety, depression, perceived stress, academic behaviour, academic procrastination, academic burnout, emotional intelligence, subjective well-being, Self-control, motivation and addiction, self-esteem, body image, sense of inferiority, and social support.
TOPICALITIES AND MECHANISMS FOR ASSURING QUALITY OF BORDER GUARDS\u27 PROFESSIONAL TRAINING
Get PDF The topicality of the research is determined by the present day challenges within the frame of the EU border security field and space of professional education, which directly project onto the quality requirements for professional training of employees of Latvian law enforcement institutions.Research aim: on the basis of the analysis of quality management aspects during the educational process of professional training in law enforcement education institutions of the Baltic countries, to develop and approbate a model for establishing the basic principles of creating quality management systems (QMS) and methodology of the use of this model; to determine the most topical and effective basic principles of developing QMS in education establishments of law enforcement institutions. To achieve the aims of a quantitative-qualitative research, the theoretical (analysis) and empirical (data collection, synthesis and modelling, data processing) methods have been applied.

LATVIAN HIGHER EDUCATION INSTITUTION STUDENT FOREIGN LANGUAGE LEARNING STRATEGIES
Get PDFThe study focused on the frequencies of Latvian higher education institution student self-reported foreign language learning strategies. From the 86 participants 44 were males and 42 – females; sport science was studied by 48 respondents, and health care by 38; 44.20% were freshmen and 55.80% - sophomores; 76.70% were full-time and 23.30% – part-time students. The study employed the Strategy Inventory for Foreign Language Learning (SILL), consisting of 50 statements divided into 6 categories: memory, cognitive, compensation, metacognitive, social and affective. One statement from the memory strategies was removed, as it was considered non-relevant for the students. Likert scale of three choices - never, sometimes and often – was used. SPSS Version 26 was used for the data analysis. Results: 1) the investigated students tended to use cognitive (mean =2.12; st.dev.=0.29; min,=1,43; max.=3) and compensation (mean =2.11; st.dev.=0.36; min.=1,33; max.=2.83) strategies more often; 2) the students tended to use affective (mean =1.78; st.dev.=0.39; min.=1.00; max.=2.67) strategies less often; Wilcoxon Signed Ranks Test showed that compensation strategies are used more often than memory strategies (Z=5.08; Sig. =0.00) and metacognitive strategies were used more often than affective strategies (Z=5.00; Sig. =0.00).
INTEGRATED LEARNING IN A MODERN SCHOOL IN THE CONTEXT OF DISTANCE EDUCATION
Get PDFThe article is aimed at defining the concept of integrated learning and features of the implementation of this educational technology in modern general education institutions. In defining the key concept, the mechanisms of integration between the basic disciplines, which are appropriate for the use of integrated learning in the modern school, are considered. It is noted that integration can be carried out by two key mechanisms, each of which is aimed at the perception of pupils of the surrounding world as a whole, regardless of which aspect of science is its knowledge.The article reveals the essence of the integrated approach to education, its significance and impact on changing the structure of a particular subject, which is an important element in improving the effectiveness of the educational process. In addition, the article describes in detail the action of mechanisms in the implementation of the basics of an integrated lesson, as well as the content and operation of didactic principles for implementing an integrated approach.The main research methods are: Analysis of literature sources, observation, survey, generalization and statistical analysis.The article focuses on identifying opportunities for introducing distance learning into Ukrainian education using an integrative approach.The main results of the study give grounds for asserting that the active and professional use of distance education opportunities by teachers will contribute to solving the educational problems that have arisen in modern Ukraine. These changes will help build new ways of development and prospects for Ukrainian educators, based on the relevance and widespread use of online education.The authors proposed their own definitions of the concepts "value orientations", "personal values", "value orientations of Ukrainian youth".
SPECIFICATIONS OF «MANAGING» THE EDUCATIONAL PROCESS IN THE CONDITIONS OF DISTANCE LEARNING (EXPERIENCE OF UKRAINE)
Get PDFThis publication focuses on the practice of implementing non-standard approaches to standardized educational processes. The involvement of students in the practical study of the possibilities of using a virtual classroom not only as a basic model for the transfer and testing of knowledge, but also to improve the emotional response and involvement in the educational process. This is due to the inclusion of art therapy technologies, its elements, and individual practice-oriented exercises in the structure of classes, which are inherently training.That is why in this publication we turned to the demonstration of the results of the survey, interviews with the participants of our classes. In particular, not only those with whom we have been working consistently and systematically for more than one year, but also those who study under other programs without the inclusion of the technologies and exercises we offer. In addition, to demonstrate the effectiveness of this method of managing the educational process, we propose to review the work with the use of the proposed inclusions when working with a «new» audience in the process of participation and presentation of the results of interaction with participants of all-Ukrainian conferences.
