USING INFORMATION TECHNOLOGIES IN «BIOCHEMISTRY» TEACHING OF MEDICAL UNIVERSITY STUDENTS

The aim of the article is the description of a teaching software and the use of educational technology used in the discipline «Biochemistry», and the analysis of its effectiveness.Methods. The methods used in the work: a survey of students, observation, use of services Web 2.0: 1) Google Docs – for the development of questionnaires and statistical accumulation of responses; 2) You tube – for the development and publication of educational videos; 3) mindmeister.com – to prepare the mental maps; 4) Designerhttp://learningapps.org – to develop the game tasks. Results and scientific novelty. The possibilities of information technologies are analysed; the services to help develop a teaching support the learning process on the subject «Biochemistry» are selected. The references to scientific portals on the topic of this course are systematized. Subjects that attract the greatest interest of students are revealed and designated: «Protein metabolism», «Carbohydrate metabolism», «The enzymes and their importance in laboratory diagnosis». According to the identified themes the elements of the educational and methodical maintenance of the discipline «Biochemistry» on the basis of relevant services Web 2.0 are developed and tested. The high interest of students in mastering the discipline represented by the elements is found out. The proposed guidelines for teaching the subject «Biochemistry» based on acombination of traditional forms of learning are combined with the active use ofthe capabilities of modern information technologies.Practical significance. Developed by the authors technique can be used in planning and conducting of group and team work of medical university students while studying the fundamental disciplines of the university, as well as in the process of enhancing the skills of general practitioners.Цель статьи – описание учебно-методического обеспечения и образовательных технологий, применяющихся при обучении дисциплине «Биохимия», и анализ их эффективности. Методы, задействованные в работе: анкетирование студентов; включенное наблюдение; использование ресурсов сервисов Web 2.0: Google Docs – для подготовки анкет, проведения анкетирования, обработки и накопления статистики ответов; Youtube – для разработки и публикации учебных видео; mindmeister.com – для оформления ментальных карт; конструктора http://learningapps. org – для разработки игровых заданий. Результаты и научная новизна. Проанализированы возможности информационных технологий, выбраны сервисы, позволяющие разработать учебно-методическое сопровождение процесса обучения предмету «Биохимия». Систематизированы ссылки на научные порталы по тематике данного курса. Выявлены и обозначены темы, которые вызывают наибольший интерес для студентов: «Белковый обмен»,  «Углеводный обмен», «Ферменты и их значение в лабораторной диагностике». По перечисленным темам разработаны и апробированы элементы учебно-методического обеспечения дисциплины на основе соответствующих сервисов Web 2.0. Зафиксирован выросший интерес студентов в овладении курсом «Биохимия» посредством представленных элементов. В предложенных методических рекомендациях для обучения студентов медицинского вуза традиционные формы подготовки сочетаются с активным использованием возможностей сервисов Web 2.0. Практическая значимость. Разработанная авторская методика может быть полезна не только при планировании и осуществлении групповой и коллективной работы студентов медицинского университета, изучающих фундаментальные дисциплины, но также в системе повышения профессиональной квалификации практикующих врачей

Research on physical characteristics of hydraulic filling mass

This paper presents the experimental results of the filtration coefficient, samples density and porosity value changes on the basis of concreteferruginous quartzite beneficiation tailings against humidity in the range 1-30%. Specified dependencies are characterized by approximation reliability of 0,87-0,96 and can be used when choosing the ways of directed impact on hydraulic filling mass allowing to change its conditio

Creation of a Nanomodified Backfill Based on the Waste from Enrichment of Water-Soluble Ores

The paper analyzes losses during the development of low-value water-soluble ore deposits. The importance of development systems with backfill is shown. The use of industrial wastes of water-soluble ores to replace specially produced inert components in the preparation of backfill seems to be a good way to utilize the

Effects of mechanical activation on the structural changes and microstructural characteristics of the components of ferruginous quartzite beneficiation tailings

The effects of mechanical activation in a planetary mill on the structural changes and microstructural characteristics of the components of ferruginous quartzite beneficiation tailings generated by wet magnetic separation process were studied using X-ray and laser diffraction methods. The results revealed the relationship between variations in the mean particle size of activated powders and the milling tim

Fine-dispersed and nano mineral particles in mining and metallurgical wastes after commercial and laboratory grinding

yesThe paper presents the results of defining the content of fine-grained fractions and nanofractions in mining wastes and the correlation equations for express estimate of powder dispensability. The authors discuss the non-uniqueness of the “fine-grained mineral particles and nanoparticles” notions in scientific literatureBelgorod State Universit
