There are 6 common problems faced by students in eLearning classes and which they need to be solved through proper initiatives for the students’ future benefits:
- Productive work
- Adaptability Struggle.
- Technical Issues.
- Computer Literacy.
- Time Management.
Especially important is the ability to express your technical thoughts and ideas with the help of drawings, which is achieved when studying the basic course “Engineering and computer graphics “. As a result of mastering the course, students get the skills to read drawings, depict details and assembly drawings on them, as well as knowledge of the standards of the Unified Design Documentation System (ESKD).
Productive work with drawings is impossible without the ability to think spatially, that is, without the ability to represent the shapes of objects and their relative position in space. This becomes especially true in working with new technical means, in the development and design of modern devices and the technology for their manufacture.
Graphic literacy is the most important component of the knowledge of a good specialist, because the language of graphics is an international language of communication. “Engineering Graphics” is the first discipline of the engineering cycle that students are introduced to.
How to Study Effectively – Improve Study Skills
Freshmen embarking on a study. engineering graphics, need the development of spatial imagination and spatial-spatial thinking [1, р. 392]. It is assumed that students entering a technical university should have a base for studying descriptive geometry, however, a teacher often needs to conduct additional classes to generalize and consolidate knowledge about geometric bodies and figures, to develop skills in working with drawings and analyzing the geometric shape of an object, since in many schools do not take a drawing course. The work programs of the university, due to the limited number of academic hours, cannot allow teachers to fill in the gaps in basic knowledge that should have been given to students at school. Reducing the number of academic hours for the study of general educational disciplines while maintaining the necessary volume of knowledge, skills and abilities leads to the fact that part of the course is stated and assimilated only at the level of concepts. Therefore, the teacher needs to use methods that increase the productivity of work in the classroom.
The use of modern technical means (multimedia installation) at a lecture lesson increases its effectiveness and allow for the same time to provide more information and to activate students. The undoubted advantage of lectures and presentations is the clarity of images and inscriptions, the ability to return to previous slides. The use of computer technology makes it possible to visualize geometric models, their spatial forms, to demonstrate the formation of a drawing or surfaces in dynamics. Studying a course in engineering graphics involves not only mastering the necessary theoretical knowledge, but also developing practical skills. And this is achieved through painstaking independent work, the systematic implementation of all homework, bringing automatism to work with elementary drawing tools. When studying engineering graphics, traditional and innovative methods complement each other and in combination give an excellent result. So, traditional methods of working with drawings become an excellent way to think through the features of your project, allow you to feel the specifics of working with graphics, make it possible to develop spatial thinking and embody your creative ideas. At the final stage of working with a project, it becomes very convenient and justified to turn to a computer, which simplifies work and reduces the time and effort.
The course of studying the discipline “Engineering and Computer Graphics” provides for the implementation of practical work on which students become acquainted with modern methods of constructing graphic images by studying graphic editors. So, studying the basics of computer graphics is an integral part of the process of training specialists.
Freshmen quickly learn the techniques of the simplest drawing work on computers, after studying the basic theory of drawing. Even not the most powerful students in computer graphics classes are engaged with great interest. It is important to teach students how to create three-dimensional models in AutoCAD or KOMPAS. Already in the third lesson, students can independently build simple 3D models. It is of great importance that students can use the computer to view the constructed model in all projections, with sections and sections in two-dimensional drawings. At the same time, working with two-dimensional drawings helps them recreate the geometric shape of the part. Thus, 3D-technologies help even poorly trained students to develop spatial thinking.
To enhance students’ independent work in the study of “engineering and computer graphics”, various electronic educational products — electronic textbooks, electronic workbooks, and tests for self-monitoring — have proven themselves well. These innovative teaching tools create a positive motivation for the study of disciplines, stimulate the active use of computer technology in educational activities [5, p. 149]. At the same time, the student is an active participant in the educational process, he can adjust the speed of learning, choose a convenient time for himself, as well as topics for study. The use of a workbook in an electronic version, providing for the execution of tasks in the graphic editors AutoCAD or KOMPAS, gives a good result for independent work of students. Students can complete tasks at home on a computer and send them to the teacher for verification by e-mail.
A serious difficulty that slows down the rate of first-year students is their poor school preparation in geometry and drawing. There is a need not only to form the students ’knowledge, skills and abilities that the course implies, but also, first of all, to prepare them for the perception of a new subject, first filling out their knowledge gaps in a short form and building all this material in order the system. For this, teachers will have to use methods and techniques that will allow them to most effectively and at the same time set forth the basic concepts without which it will be extremely difficult to master more complex material. And finally, to achieve the best results, it is necessary to use classical drawing and computer graphics in a complex. Of course, the traditional methods of working with drawings are still primary, since it is necessary to bring to automaticity the ability to read drawings and represent the shapes of objects in space, but the computer helps.
The solve of the problems
To solve the problems and difficulties encountered by first-year students in the process of studying the course “Engineering Graphics”, it is possible to use various teaching methods and techniques. Since there are not many hours devoted to studying the course “engineering and computer graphics”, it should be extremely capacious and at the same time as efficient as possible. All components should be studied almost simultaneously during the formation of skills for working with relevant graphic editors Work with graphic editors is available even for not the most powerful students, which is a positive point. The ability to carry out design work through automated design systems for drawing and graphic documentation increases the importance of students as specialists.
