ARRANGEMENTS AND PROCEDURES FOR IMPLEMENTING INDEPENDENT WORK FOR FUTURE CIVIL AVIATION SPECIALISTS IN THEIR FOREIGN LANGUAGE TRAINING ^{[№ 2 ' 2025]}
The organisation of students’ independent work is a key component of modern language training for future specialists in the aviation industry. The challenges encountered by students include limited classroom time, the complexity of professional terminology, insufficient preparation for independent study, and the necessity to attain a sufficient level of proficiency in a foreign language. It has been established that students have difficulties in independent study of the material, which reduces the quality of knowledge acquisition and the formation of professionally important competences. Consequently, there is an obvious need to develop effective methods of organising independent work that will enable students to successfully master a foreign language and apply it in their future professional activities. During the research process, we analysed various forms of independent work, including classroom and extracurricular tasks, as well as ways of combining them. The implementation of activity and competency approaches allowed us to create conditions that encouraged students to explore and analyse information actively, with the aim of enhancing their motivation and involvement in the learning process, as well as increasing their level of independence. We integrated project-based assignments, pair and group work, interactive technologies and a system of control and self-monitoring. The results have demonstrated that the implementation of these techniques contributes to the development of students’ ability to independently search and analyse information, improves the quality of task performance and the level of foreign language proficiency. We have determined that a complex approach to the organisation of students’ independent work allows us to increase the effectiveness of language training. The establishment of conditions conducive to purposeful independent learning fosters stable motivation to master a foreign language. Furthermore, it develops the competencies of self-control and self-organisation, thereby enabling future aviation industry specialists to adapt to the demands of international interaction.

BIOECOLOGICAL EVALUATION OF THE ARTIFICIAL POND MODEL UNDER EXPERIMENTAL METALS CONTAMINATION IN THE NANOFORM ^{[№ 5 ' 2017]}
In the course of production, nanoparticles inevitably enter the environment, including water, which leads to a change in the quality of water and poses a danger to aquatic organisms. In this case, it is expedient to study the evaluation of the effect of metal nanoparticles on aquatic hydrobionts on survival indices, identifying potential risks that arise when nanoparticles of these metals enter aquatic biocenoses. In this paper we made bioecological evaluation of artificial pond model under experimental contamination with nanoparticles such as Fe, Fe₃O₄, Ni, NiO, using Lemna minor L., Limnea stagnalis, Danio rerio as model organisms. There were revealed specific adaptation features of organisms with different levels of organization to the presence of corresponding nanoparticles in the habitat with limits assessment of their tolerance. During the organisms survival test under conditions of modelled aquabiocenosis, a number of methods were chosen to increase toxicity from nanoparticles to iron oxide nanoparticles regardless of the concentration and the Ni→NiO→Fe→ Fe₃O₄ exposure period. It is shown that nanoparticles of iron and its oxide in all investigated concentrations, represent a great danger for hydrobionts in the conditions of artificially created aquabiocenoses, than Ni and NiO nanoparticles, due to greatest toxicity.
