In our research work, 5320300-technological machines and equipment direction of education in order to develop certain skills related to research, design, use and service, production-technological and organizational-managerial activities, presented in the DTS and qualification requirements, we developed the methodology of course project implementation on the subject of' machine details "in support of' Veer " (Elpigich) technology from innovative educational technologies. Description of the technology "Veer". This technology is complex and multifaceted, aimed at studying problematic topics.
The essence of technology is that the bunda is given a single piece of information on different branches of the subject. For example, pros and cons, advantages and disadvantages, benefits and losses are determined.
This interactive technology allows students to successfully develop critical, analytical and clear logical thinking, as well as to express their ideas, thoughts in written and oral form in a concise manner, as well as to protect it.
- The technology "Veer" is aimed at the active work of small groups, each participant and groups in general, which discuss some branches of the general topic.
- The technology "Veer" is at different stages of studying the subject:
- in the beginning - free activation of their knowledge;
- in the process of studying the subject - deep knowledge and understanding of its basics;
- at the stage of completion - the acquired knowledge can be applied in order.
Basic concepts that you will encounter in Veer technology:
With the aspect (point of view), the subject, phenomenon, concept are checked.
Advantage-superiority in comparison with something, privilege.
Virtue is a positive quality.
Defect-imperfection, inconsistency with rules, criteria.
In addition to education, the technology "Veer" has an educational character:
- skill of working in teams, groups;
- skill to discuss problems, situations from different perspectives;
- ability to find compromising decisions;
- respect for the opinion of others;
- kindness;
- creative approach to work;
- activity;
- ability to concentrate attention on the problem also allows the formation of such qualities as mastery [33, 45-p. ].
The course project is carried out by the students themselves independently, individually, in consultation with the leader, based on the assignment given on the option. In the course of the course project, students: Higher Mathematics, Physics, Theoretical mechanics, Informatics and Information Technology Sciences in mathematical and Natural Sciences; performs in general scientific disciplines: Materials Science and construction materials technology, material resistance, drawing geometrics and engineering graphics, machine theory and engineering, self-reliance on the knowledge and skills acquired in the subjects of standardization and technical measurements.
Based on Veer technology, depending on the number of students in the group, it is divided into several subgroups and divided into separate sections in the assignment of the course project into small groups. In addition to the individual implementation of the course project, students conduct research on the topic chosen in small groups.
In the group we divide 27 students into 9 subgroups. In each small group, 3 students are a team and work on their own assignment. At the end of the semester, before the defense of the course project, each small group gives a presentation on the results of the assignment given to them. The materials of the presentation will be discussed with the participation of the students of the group. Students who actively participate are encouraged. Each section, which must be completed on the assignment of the course project, is distributed in groups. For example, let the group have the task of completing the project on the topic "design of a conveyor belt with a two-stage cylindrical wheel reducer".
