ELEMENTS OF DIGITAL PEDAGOGY FOR BACHELORES OF TECHNICAL SCIENCES IN THE CONTEXT OF THE SAMR MODEL ^{[№ 1 ' 2024]}
Digital pedagogy is becoming an integral part of the educational process in universities. Digital educational resources in modern education occupy a significant share of content and, in their influence on the formation of competencies, can compete with classroom work in contact with a teacher. Digital didactics, as a set of techniques that make it possible to effectively use digital resources in teaching, may include different approaches to the problem of attracting students’ attention to the material of a course or discipline. The SAMR model (Substitution, Augmentation, Modification, Redefinition) clearly demonstrates these approaches and highlights levels or stages, the design of which allows the teacher to productively use the capabilities of digital didactics to achieve educational goals. The development of digital pedagogy should provide the opportunity for the teacher to build developmental applications to achieve pedagogical goals in building individual educational routes, to personalize the process of achieving results of developing competencies, to diversify the learning process, and to reduce the time spent on situational control of knowledge, redistributing it to a program of cooperation and joint creativity in the implementation process of appropriate teaching strategies.

VARIATIVE CONTENT MODEL OF THE WORKBOOK FOR GRAPHIC DISCIPLINES WITH INFOGRAPHIC ELEMENTS ^{[№ 3 ' 2022]}
Modern learning technologies are increasingly using the capabilities of the digital educational environment, in the content of which consists of various types of presentations, training videos, sets of slides and illustrations play a significant role. When conducting an observational experiment and recording the data of intermediate certifications of students, it was revealed that visual means of presenting material definitively help the development of perception of spatial objects, their relative position and transformation. However, the results of such training are often not consolidated in the form of educational achievements in the form of skills, abilities, and mastery of elements of general professional competencies. The methodological support of the educational process in order to improve the quality of education can be supplemented by a workbook, which combines the visual perception of the material with the need to consolidate skills when working directly with a pencil in a notebook. Infographics of slide pages, formed while taking into account the principles of fundamentality, purposefulness and adaptability, allows you to activate visual memory, increase interest in the discipline, “keep” attention and teach you to focus on the main, key positions of the educational material. The principles of visibility, uniformity, continuity in the selection of material ensure a solid development of general professional competencies, which is relevant in light of new accreditation indicators for universities. A variative model of the content of the engineering graphics workbook has been developed, which defines the types, tasks, functions, principles, stages and approaches to the selection of the subject content of the discipline. The variability of the model allows using the most significant components to take into account the peculiarities of the contingent of students. The model can be applied to work on this type of methodological development to improve efficiency in teaching other disciplines at the university.

SEWAGE TREATMENT USING CHITOSAN ^{[№ 10 ' 2015]}
This paper studied the unique properties of chitosan and its use. The technology of obtaining chitosan from shellfish waste recycling field, ie the shell of walking limbs Kamchatka king crab. The characteristics of the chemical composition of the shell. Showing the steps of isolating chitin chemically — a stage of demineralization and deproteinirovaniya. The technology of chitosan production is the reaction from the cleavage of the structural unit of chitin acetyl groups represented in the article. Chitosan is obtained by the presented technology used for wastewater treatment from cations of heavy metals and suspended solids. We prove that the wastewater treatment from suspended solids using chitosan is more effective in a shorter period of time. Includes photographs of wastewater containing suspended solids without and after treatment with a solution of chitosan. Also investigated were the model waste water containing heavy metal cations (Cd²⁺, Pb²⁺, Zn²⁺), which was added to purify the chitosan solution in 2% acetic acid in different ratios. It was found that the optimal ratio of chitosan solution to the model drains is 10 ml per 1 000 ml of solution, further increasing chitosan supplements are not advisable. Efficacy effluent from heavy metal ions by chitosan is from 50 to 80 % and depends on the nature of the metal cation. The most effective wastewater treatment is achieved for cadmium cations.
