Problem statement. The description of a pedagogic research in the field of formative assessment theory and practice is presented. The goal of the study is to define pedagogic and methodological conditions for effective evaluation of ESP students’ learning outcomes in a digital learning environment. Methodology. On the basis of key theoretical provisions of formative assessment and interdisciplinary approaches LSPCLIL, a complete set of criteria-based ESP evaluation tasks and assessment schemes were developed for Business English course delivered in the groups of BMSTU masters students majoring in economics. The approach to grading that correlates with BMSTU point-rating system was substantiated. The comparative analysis of modern platforms allowed to select the domestic service pruff.me, which was used as a ground for a digital assessment space (DAS), a part of BMSTU digital learning environment needed for implementing formative assessment of ESP learning outcomes. Results. The developed evaluation materials integrated in the DAS were tested by ESP students in a distant format. Conclusion. The research showed that creating DAS as an essential component of a university digital learning environment can contribute to effective assessment of ESP students’ competence-based learning outcomes provided that underlying methodology is taken into account and formative assessment technology is implemented in full volume.

Abstract. STREAM_2D software package was applied to retrospective and predictive simulations of the Lena River near city Yakutsk hydraulic and channel changes during ice-free period. The modelling results indicate significant correspondence of simulated water discharges distribution and water levels with observed ones for the period 2001–2016. Model has captured main erosion and depositional zones observed in the 2009–2016 years. Combination of typical monthly average hydrographs of 1 %, 10 % and 50 % return intervals was used as an initial parameter for 10-year channel changes forecast. According to the simulation results, degradation of the Adamovskaya branch will be continued, which is the most negative impact for the Yakutsk city infrastructure maintenance. At the end of the forecast period the equal distribution between Adamovskaya and Buorylarskaya channels is possible, which is a positive trend from the point of view of the city water supply system.

The guide vane of a centrifugal multistage pump mostly determines the hydraulic efficiency of the pump and as a consequence the optimal mode of its operation. In order to increase the pump efficiency, the radial channel guide vane has been optimized. Three geometrical parameters and the number of channels of the guide vane were selected as optimization parameters. Hydraulic efficiency was chosen as a criterion. 128 computational models were obtained by the method of automated parametrized construction. The efficiency parameters were obtained via hydrodynamic modeling. As a result, a significant increase in the pump efficiency was achieved.

Various studies show that the centrifugal multistage pump guide vanegreatly determines the hydraulic efficiency of the pump and, as a result, the optimal mode of its operation. In order to increase the pump efficiency, the radial guide vane with a no-blade transfer channelwas optimized. Three geometrical parameters and the number of channels of the guide vanewere chosen as optimization parameters; the hydraulic efficiency was the optimization criterion. 128 computational models were made, and the efficiency values at the operating point were obtained by the method of hydrodynamic modeling. As a result, significant increase in the pump efficiency was achieved.

The current level of development of information systems, the introduction of technology in all aspects of life and the ever-accelerating process of digitalization also affect school education. Students increasingly notice the gap between the classical form of presenting material and the capabilities of modern information systems. Especially acute, in our opinion, this problem concerns the study of geography. The study of geography by traditional methods is not only ineffective and discourages students from learning but does not meet the requirements of the federal state educational standard. The teaching of geography should be conducted with the introduction of geoinformation technologies. Based on this thesis, to solve the problem we have voiced, the creation of a textbook is proposed. In our demonstration manual, based on the requirements of the federal state educational standard, 4 blocks of tasks were identified. The solution of these problems is aimed at developing the ability of students to form relationships and see dependencies using a layered organization of data. A set of layers for solving problems consists of the actual data needed to solve a specific task. All tasks are printed on translucent paper so that students have the opportunity to see the previous layers and analyze their relationship, formulate conclusions about the connection of phenomena. Also the manual has a section with questions aimed at helping students to formulate their thoughts when writing an answer, and ready-made templates with sample answers for self-testing and understanding the general principle of an answer generation. Due to epidemiological restrictions, the testing of the textbook took place remotely in one of the schools in Perm.
