: e circumstances of active implementation of a blended learning format at all educational levels require increased motivation and advancement of the competences learned by students of higher education institutions.Such statement equally applies to foreign language competence, which is one of most relevant skills to the future professional activity of international relations specialists. In considering this, the Ukrainian higher education institutions conducted a study on the development of foreign language competence of higher education students in the context of blended learning. e purpose of the article is to develop and empirically establish the eﬀectiveness of the author's model of foreign language competence development of higher education students in the context of blended learning. e study involved the development, implementation and evaluation of the eﬀectiveness of the author's model of foreign language competence development of higher education students in the context of blended learning. e participants of the study were students of higher education institutions: HEI 1, HEI 2, HEI 3, who majored in the following specialties:

participants were 1st, 3rd and 5th year students.A total of 138 students were interviewed (68 from the experimental and 70 from the control group).e study confirmed that the implementation of the method of organizing the formation of foreign language competence of higher education students, which requires an optimal combination of blended learning with modern digital tools and the professional orientation of foreign language training in the system of higher education institutions, helps advance foreign language competence of higher education students.Keywords: Blended learning, Competence, Educational process, Foreign language, Students.

INTRODUCTION
Knowledge, skills, and high level of foreign language proficiency form an essential component of professional competence of a modern specialist, thus being crucial in professional training of higher education students.Such statement is particularly relevant for students majoring in international relations and international activities.For students majoring in purely technical specialties, in particular, future specialists in applied physics and mathematics, nanotechnology, mining, ecology, and heat power engineering, foreign language knowledge and skills are equally important since they open for students the opportunities for world achievements and exchange of experiences in a barrierfree communicative environment in these crucial areas of activity.Imporantly, such students have toattain a high level of foreign language competence in order to achieve professionalism in their future activities and build their professional careers.Despite the fact that higher education institutions pay considerable attention to the development of foreign language competence of students, the teachers' community is continuously searching, developing, testing and implementing effective technologies, methods, and techniques of teaching foreign languages to students majoring in international relations, applied physics and mathematics, nanotechnology, mining, ecology, and heat power engineering.e active implementation of distance learning technologies into the overall training system in higher education institutions and observance of social restrictions necessary to combat the global pandemic have significantly transformed the educational process.is highlighted the need to introduce models of blended learning as a certain consensus between traditional fulltime and distance learning.Such conditions caused the increase in the responsibility of the teaching personnel of higher education institutions for the formation of professional competencies of students.Teeaching foreign languages in such conditions necessitates the implementationof particular corrective and adaptive methodological tools that might be effective in organizing the educational process focused on the acuisitionof foreign language competence in the blended learning format.

Research design
e study involved the development, implementation and evaluation of the effectiveness of the author's model of foreign language competence development among higher education students in the context of blended learning.e study included the following stages: statement, formation, control.At the ascertaining stage, the preparatory preparation of the subjects of the educational process (students and teachers) to work in a blended model of education was carried out, the introductory monitoring of the formation of foreign language competence of higher education students was carried out.
At the ascertaining stage, preparatory guidancewas provided to the educational process subjects (students and teachers) to work in the context of blended learning, and the introductory monitoring of the level of foreign language competence among higher education students was carried out.e formation stage entailed the development and implementation of the author's model of the development of foreign language competence among higher education students in the context of blended learning.At the control stage, the final monitoring of the foreign language competence level of higher education students was carried out, and the effectiveness of the author's model of foreign language competence development of higher education students in the context of blended learningwas assessed based on a comparative analysis of the monitoring data received at the ascertaining and control stages of the research.

Sample study
e participants of the study were students of higher education institutions: HEI 1, HEI 2, HEI 3, who majored in the following specialties: international activities, international relations, applied physics and mathematics, nanotechnology, mining, ecology, heat power engineering.eparticipantswere1st, 3rd and 5th year students.
Intervention e implementation of the suggested model of forming foreign language competence among higher education students in the context of blended learning within the scientific research involved intervention in the educational process of three institutions: HEI 1, HEI 2, HEI 3.Such intervention was made upon consent of the administration, teachers and student communities.

Limitations
Monitoring and experimental procedures involved the total of 138 students aged between 17-21.e introductory monitoring was conducted at the beginning of the first semester of 2020/2021 academic year.e author's model wasintroduced during the first semester of the academic year.e control stage of the experiment was implemented in the second semester of 2020/2021 academic year.e only difference in the implementation of the model in the first, third and fih years, respectively, is the volume and complexity of lexical and communicative material, while the concept of the model itself remains unchanged.

Statistical analysis
e monitoring performed at the statement and control stages of the research involved the implementation of test tasks approved at the faculties of the experimental bases.e survey of students was carried out through Google forms.Recording and processing of results was carried outin Excel spreadsheet.
Monitoring at the ascertaining and control stages of the research involved the implementation of test tasks approved by the departmental experimental bases.

RESULTS
e scientific researchwas focused on the elaboration of an author's model of foreign language competence development oigher education students in the context of blended learning.e suggested model includes the following components (Figure 1): motivational and cognitive, practical and action-related, improvisational and creative, value and ethical, communicative and reflexive.e motivational and cognitive component of the model assumes that the student has a constant desire to improve and correct the current level of foreign language competencedevelopment, and is based on a clear algorithm for further acquisition of knowledge, skills and abilities within the blended learning format.
e practical and action-related component is characterized by the ability of the higher education student to demonstrate the current level of development of foreign language competence in performing professionally oriented tasks according to the program suggested by teachers and with regard topersonal learning capabilities in the context of blended learning.
e improvisational and creative component involves the formation of students' ability to act in atypical and contradictory speech situations without prior training and demonstrate creative approach to solving non-standard professional situations without teacher's assistancein the context of blended learning.
e formation of the value and ethical component is intended to develop among higher education students a clear and stable system of value orientations, facilitate the perception of foreign ethical norms and standards outside face-to-face communication, and increase the ability to use the established values and ethical norms in real professional communications.
Considering the communicative and reflexive component of the model, it is necessary to focus on the level of communicative potential of the student, his excellence in foreign speech, success of the professionally oriented communicative transactions, and the ability to evaluate the success and effectiveness of real-time and other types of communication.
For each of the components of the suggested model, it is recommended to use various tasks and createparticular organizational and pedagogical conditions.
To implement the motivational and cognitive component of the model in the context of blended learning for ensuring the development of foreign language competence, it is advisable to use advanced searching tasks, work in small groups, organize offline creative projects and apply training technologies.e effectiveness of the implementation of the practical and action-related component of the model depends on students'success in solving real educational and professional situations by using the foreign language material learned, as well as on the use of professional quests.
To implement the improvisational and creative component of the model, it is advisable to design non-standard professional situations that would require not only the application of speaking skills, but also a creative approach to solutions.Importantly, such situations should be spontaneous and reflect the most accurate picture of reality.
e requisite for the implementation of the value and ethical component of the model is the elaboration of speechbehavioral models with regard to the specificity of the multicultural environment and the target audiences by mandatorilyfollowing the established ethical clichés of the foreign language.
e implementation of the communicative-reflexive component can be achieved through the performance by students of the task of self-and mutual evaluation of the effectiveness of their communicative acts of particular thematic orientation.
To ensure the successful implementation of the proposed author's model, all subjects of the educational process should be adaptable, mobile, tolerant and motivated.Adaptability is crucial for students to be able to quickly adapt to transformational educational challenges and reconfigure the system of teaching and learning accordingly.Mobility is the trait necessary for students and teachers to be independent from learning conditions and work towards excellence.Tolerance will facilitate adequate response to diversity in teaching and learning.If motivated, the subjects of the educational process will be able to overcome any barriers and adequately respond to new challenges, actualized by the active introduction of blended learning.
Organizational and pedagogical conditions for the implementation of the suggested model include: establishment of a positive microclimate in the relationship between the subjects of the educational process; formation of a tolerant attitude to the expansion and diversification of teaching methods and techniques; sufficient and high level of ICT competence of the subjects of the educational process; realization of the optimal combination of methods, techniques, forms of work, and learning technologies; rational distribution of the educational materialswith regard to individual features of groups and the organizational pattern of the educational process.
e system of tasks suggested within the author's model was developed in consideration of all its components andthe fields of study (international relations, applied physics and mathematics, nanotechnology, mining, ecology, heatpower engineering) and was broadcast to students through Google Classroom, Zoom, WhatsApp, Instagram, and Viber: 1) Prepare a scenario plan for an online international meeting with foreign partners.Send the presentation to the teacher for assessment.e dialogues suggested within the scenario plan should be discussed during the training sessions.

DISCUSSION
e conducted research illustrates the transformation of the roles of the educational process in the context of blended learning.Relevant in this context to ours is a study that shows the prospects, benefits of blended learning, interactivity, but at the same time notes the lack of constant direct contact (Kacetla, 2020).e study that is relevant to the presented research in this context confirms the viability and benefits of blended learning and interactivity, yet provides evidence on the lack of constant direct contact (Kacetla, 2020).Similarly to the presented experiment, the scientific research of applied nature illustrate the positive effect of blended format on motivation to improve skills in different types of speech activity and emphasize the mandatory nature of due positive attitude of the student community to this format of knowledge acquisition.Google Classroom proved particularly effective for selection and testing of various toolsof the implementation of blended learning model (Taufiqurrochman, 2020).Since the suggested tasks entail the application of various digital tools depending on students'resources, it is necessary to consider not only strengths, but also challenges of the blended learning model.Nevertheless, both our scientific research and other studies show that the strengths of blended learning outweigh its limitations.Importantly, students positively appreciate the use of bright images, video, audio, reading texts, chatting, and discussion forums in foreign language education (Gulnaz, 2020).e procedure similar to the one followed in the presented study is based on the integration of traditional and blended learning models.In its course, students visited the institution once a week and had only a one-hour meeting, and at other times had to watch educational videos through an electronic platform set up by the university and participate in an online discussion forum.
e key difference between the results of our research from similar scientific research ofan applied nature is the implementation of the methods of providing the formation of the foreign language competence among higher education students, which is based on an optimal combination of blended learning with modern digital tools and professional orientation of the foreign language training in the system of higher education institutions.

CONCLUSION
e effectiveness of foreign language training of higher education students in the current conditions of social distancing depends on the rational construction of a blended learning model.e implementation of the suggestedblended learning model, which is based on the consolidation of digital tools with professionally oriented didactic support, facilitates the advancement of the foreign language competence of higher education students.
Maximum orientation of the model on the digital awareness of students and focus on professional and practical speech situations guarantee the increase in students' motivation to advance foreign language knowledge, skills and abilities and further contribute to a high level of the the foreign language competence development of higher education students.
e prospect for further research in this area is the joint development by foreign language teachers from Ukrainian universities and ICT specialists of digital products (modular environments, virtual communities, professionally oriented blogospheres), which will facilitate the implementation of a blended format of education for the acquisition of foreign language competence by future specialists in such fields as international relations, applied physics and mathematics, nanotechnology, mining, ecology, and heat power engineering.
