Implementation of electronic learning resources into the teaching of chemical disciplines in higher school does not always lead to an improvement in students' mastery of the material. Therefore, the optimal choice of effective electronic resources for the teaching of basic chemical disciplines is an urgent task. The purpose of the work was to identify the resources that are relevant to the teaching of physical chemistry from the point of view of both teachers and students. Specific questionnaires were developed to achieve the goal, and a survey of pedagogical process participants (students and faculty members) was conducted, followed by statistical processing of the survey results. The expediency of usage of 41 e-resources was investigated, and 21 resources were identified as suitable for the study of a university course in physical chemistry. Among them, eight e-resources were found to be important for teaching most topics of the discipline, and so are attributed to universal resources. Another thirteen resources are important for teaching some topics and ineffective for others (specific resources). At the same time, only five universal and eight specific resources are currently used in the practice of the Faculty of Chemistry of Olesj Honchar Dnipropetrovsk National University. Some discrepancies have been identified between teachers and students concerning resource preferences that create the preconditions for the loss of effectiveness of the use of such resources. Since the use of some electronic resources is sensitive to learning styles, existing styles for faculties and students were analysed. The main differences consist in the explicit preferences of the faculty for reflective and global styles, while students are characterised by predominantly active and sequential learning styles. The results obtained regarding the effectiveness of e-resource usage are discussed from the viewpoint of preferences in learning styles characteristic of students and teachers of natural sciences.

Anatoliy Haidenko’s creative path lasts for about sixty years, during which this outstanding musician has been working fruitfully as a composer, performer, teacher, scientist, methodologist, music and public figure. The versatility of his personality, the diversity of talents, the relentless search for new ideas or means of expression, interest in a wide range of current issues of today are fully manifested in each of these areas. The desire to keep up, not to miss any opportunity to do something for people and at the same time to find time to «create» music in the silence of the cabinet led to a fair recognition of the achievements of Anatoliy Haidenko, currently an honored artist of Ukraine, professor, winner of numerous prestigious awards, permanent member of the jury of national and international festivals and competitions. Background. The figure and work of Anatoly Haidenko often attracts the attention of music scholars. In the field of view of researchers there were, above all, the issues of biographical and aesthetic nature, which are the necessary foundation for a thorough study of the artist’s work. Genre searches and stylistic principles of creativity are another important vector of research, based on analytical observations of Anatoliy Haidenko’s music. However, unfortunately, there are few special works dedicated to the creative work of the Kharkiv composer. Separate pieces of information about some of his opuses, as a rule, are contained in works aimed at highlighting certain trends in modern Ukrainian, especially accordion music. Thus, in order to establish the worldview of the composer, his creative and aesthetic principles, it is necessary to review the available in domestic musicology knowledge about Anatoliy Haidenko and his music. The purpose of the article is to highlight the figure of the artist and his contribution to the Ukrainian academic music art. The material of this research. Analyzing the scientific sources that cover the figure of the outstanding artist A. Haidenko, it is necessary to single out the meaningful work of the monographic type by A. Semeshko (2010) from the series “Portraits of modern Ukrainian composers” about the life and career of A. Haidenko. T. Bolshakova’s textbook (2007) “Concert works for accordion by A. Haidenko” is, in fact, a detailed preface to the publication of musical texts of accordion works of the composer, which had not been published before. The scholar focuses on the artist’s inherent synthesis of modern compositional writing and Ukrainian folk music tradition, emphasizing their subordination to the symphonic thinking of the master. T. Bolshakova’s opinion is also important regarding the “neo-pantheistic concept of existence”, the manifestos of which in A. Haidenko’s works are “the figurative content and semantics of the musical language of his works” (Bolshakova, 2007). The author of the candidate’s dissertation on the topic: “Bayan creativity of Anatoliy Haidenko: aesthetic and genre-style aspects” (Yeromenko, 2019) of Sumy, defended in 2019, thoroughly researches the creative way and accordion work of A. Haidenko. Tracing the evolution of the artist’s compositional path, the researcher A. Stashevsky (2013) identifies the most significant works from his point of view, briefly characterizing them. This opinion is asserted by A. Stashevsky in fundamental work “Modern Ukrainian music for accordion: means of expression, compositional technologies, instrumental style” (2013). In this work, the composer’s work is considered in the section devoted to one of the main vectors of development of modern accordion music – folklore and neo-folklore. Conclusions. During the sixty years of his creative path A. Haidenko has been fruitfully working in various spheres of activity: composition, performance, pedagogical, scientific, methodical, musical and public ones. Performing activities began with a trip as part of a student concert. The activity, which began with travels as part of concert student brigades and continued during the work in Sumy, demonstrated the talent of A. Haidenko as a bayan soloist and ensemble player. However, later the leading role was played by the compositional and pedagogical areas of activity. As a composer, A. Haidenko went through a difficult path from the status of “amateur author” to a recognized master of large forms and exquisite miniatures. Four works, submitted by him before joining the Union of Composers of Ukraine, identified the main directions of his further creative activity: symphonic music, music for folk instruments, choral and chamber and vocal music. A. Haidenko’s teaching activity – ten years of work at the Sumy Music School, four years at the Kharkiv Institute of Culture and more than forty years of hard work at the Department of Folk Instruments at the Kotlyarevsky Kharkiv National University of Arts – contributed to the formation of their own pedagogical principles, proved by the students of A. Haidenko: Y. Alzhnev, V. Geiko, A. Zhukov, E. Ivanov, S. Kolodyazhny. A. Haidenko’s research interests are connected with the history of the Kharkiv school of composition and instrument science. The textbook “Instrumentology and Fundamentals of Instrumentation Theory”, published in 2010 and addressed to teachers and students of folk instruments departments of higher musical educational institutions, is the result of many years of experience teaching the relevant course at KhNUA named after I. P. Kotlyarevsky. A significant place in the life of A. Haidenko is occupied by musical and public activities. In the National Union of Composers of Ukraine, he has served as Deputy Chairman and Executive Secretary of the Kharkiv Organization, a member of the UWC Board and Audit Committee, and Chairman of the Music Fund. Anatoliy Pavlovych Haidenko is also a member of the National All-Ukrainian Music Union, the Supervisory Board of the Ukrainian Cultural Foundation, and regularly participates in the jury of various competitions and festivals.

The pandemic situation at the beginning of March 2020 forced teachers to develop alternative teaching methods, and most important to find the best ways to keep teaching for every student no matter the situation, as for example, the lack of computer knowledge or hardware/software support. Teachers worldwide struggled to support, encourage, find the best ways not only to help students to keep learning but support them emotionally. At the end of the academic year, teachers made efforts to develop fair, appropriate evaluation procedures adapted to distance education. This paper summarizes the Distance Teaching-Learning-Evaluation (DTLE) evolution in Russia and Romania and some methods developed from March to December 2020 to support the educational activity. Some benefits, challenges and difficulties are identified during the same period of time in different DTLE scenarios, from the point of view of teachers and students, as well. Examples of new adapted methods, dedicated to the DTLE scenarios are al-so addressed in this work.

ABSTRACT Learning is a complex construct that involves several factors, mainly the interaction between teachers and students in the process of teaching and learning. Understanding how students learn and which factors influence academic performance is essential information for lesson planning and evaluation, in addition to allowing a better use of students’ learning potential and outcomes. The ability to constructively modify one’s behavior depends on how well we combine our experiences, reflections, conceptualizations, and planning to make improvements. This seems particularly relevant in medical education, where students are expected to retain, recall, and apply vast amounts of information assimilated throughout their training period. Over the years, there has being a gradual shift in medical education from a passive learning approach to an active learning approach. To support the learning environment, educators need to be aware of the different learning styles of their students to effectively tailor instructional strategies and methods to cater to students’ learning needs. However, the space for reflection on the process of teaching is still incipient in higher-education institutions in Brazil. The present article proposes a critical review of the importance of identifying students’ learning styles in undergraduate medical education. Different models exist for assessing learning styles. Different styles can coexist in equilibrium (multimodal style) or predominate (unimodal style) in the same individual. Assessing students’ learning styles can be a useful tool in education, once it is possible to analyze with what kind of learning students can better develop themselves, improving their knowledge and influencing positively in the process of learning. Over the last century, medical education experienced challenges to improve the learning process and curricular reform. Also, this has resulted in crucial changes in the field of medical education, with a shift from a teacher centered and subject based teaching to the use of interactive, problem based, student centered learning.
