Abstract:
This study aims to improve the methodology for developing design and technological competence of
future engineers through the teaching of engineering and computer graphics. The rapid development of
technology and the increasing complexity of engineering tasks require innovative approaches to education. By
integrating modern pedagogical strategies and digital tools into the curriculum, this study seeks to improve
students' ability to effectively design, analyze and implement engineering solutions. A mixed-method approach
was used, which included the analysis of current teaching practices, the experimental application of innovative
methods and the evaluation of student results. The results show that the integration of computer modeling,
interactive design tasks and collaborative projects significantly increases the design and technological
competence of engineering students. These findings serve as the basis for the development of more effective
teaching methodologies aimed at adapting educational practices to industrial needs and technological advances.

Introduction:
In today’s rapidly evolving technology
era, the demand for highly skilled professionals capable
of solving complex industrial problems in engineering is
increasing. One of the key competencies required for a
modern engineer is design-technological competence,
which includes the ability to conceptualize, design,
analyze, and implement technological solutions. This
competence is particularly important in industries such
as
automotive,
construction,
and
mechanical
engineering, where precision, creativity, and advanced
technological knowledge are required [1]. Engineering
and computer graphics are key disciplines in developing
this competence. These disciplines increase students’
technological literacy by teaching them spatial
visualization, technical drawing, and design principles.
However, traditional teaching methods used in this
field often fail to meet the practical needs of future
engineers or do not adequately utilize the capabilities
of modern digital tools and methodologies. As a result,
many
students,
while
possessing
theoretical
knowledge, do not acquire the practical skills that can
meet the needs of industry [2].
METHODOLOGY
Integrating innovative methods into the teaching of
engineering and computer graphics, including
computer-aided design (CAD) programs, 3D modeling,
and interactive simulation tools, can be an effective
way to address this problem. This will help students
apply their theoretical knowledge in real-life situations
by making the learning process more interesting and
practical. Also, the use of project-based learning and
team assignments will help students acquire skills that
are important for modern engineers, such as critical
thinking, problem solving, and teamwork [3].
The purpose of this study is to develop the design and
technological competencies of future engineers by

improving the methodology of teaching engineering
and computer graphics. In particular, the following
tasks are planned [4]:
1. To analyze the current state of teaching engineering
and computer graphics.
2. To identify the main problems faced by students and
teachers.
3. To propose innovative teaching methods using
digital tools and active learning strategies and to
evaluate their effectiveness.
By pursuing these goals, research contributes to
aligning engineering education with the dynamic
demands of industry and preparing students to succeed
in a technology-driven world [5].
RESULT AND DISCUSSION
Analysis of advanced foreign and domestic experiences
in engineering graphics The analytical method is
important for improving educational processes and
introducing new approaches in the scientific field. In
the field of engineering graphics, this method helps to
identify the most effective approaches by studying the
teaching systems and practices used in different
countries. When analyzing foreign and domestic
experience, not only teaching methods are taken into
account, but also factors such as the general structure
of the education system, the interaction of students
and teachers, and the level of use of technologies [6].
Advanced methods of teaching engineering graphics
are widely used abroad, especially in developed
countries such as the USA, Europe and Japan. In these
countries, engineering graphics includes not only
traditional drawing skills, but also advanced
technologies such as computer-aided design and 3D
modeling. The following approaches are most often
used [7]:
In foreign educational institutions, for example, in the
USA and Europe, CAD programs such as AutoCAD,
SolidWorks, CATIA, and Rhinoceros are widely used.
Through these programs, students are given the
opportunity not only to create technical drawings, but
also to create 3D modeling and animations. Computer-
aided design allows students to develop high-
resolution technical drawings and projects, which
increases their practical skills [8,9].
In Europe and the USA, special programs (for example,
Blender and 3ds Max) are also used to teach students
3D modeling in engineering graphics classes. With the
help of these programs, students have the opportunity
to create 3D models of real-life objects and test them
in a virtual environment. In this way, students learn not
only how to create drawings, but also how they work in
practice [10].
In Europe and the USA, the project-based learning
method is widespread. In this method, students learn
by solving real engineering problems. For example,
during the learning process, students create 3D
modeling, mechanical system drawings, and other
graphic materials based on projects they develop. This
approach brings students closer to practice and
develops their project-based problem-solving skills.
In some countries, such as Japan, interactive simulation
and virtual labs are used to teach engineering graphics
and design to students. With the help of these
technologies, students can simulate various problems
that arise when creating projects, for example, taking
into account material properties, mechanical forces
and other factors, and test their projects virtually.
Engineering graphics education in Uzbekistan and
other Central Asian countries has its own unique
characteristics. Traditional teaching methods are often
focused on drawing, but in recent years modern
technologies
and
methodologies
have
been
introduced. An analysis of local experience shows the
following characteristics:
Traditional methods: In many higher education
institutions in Uzbekistan, traditional drawing and
technical drawing approaches are used as the main
method of teaching engineering graphics. This method
teaches students skills such as creating correct
drawings, maintaining symmetry and proportions, and
clearly showing details. However, this method is based
only on theoretical knowledge and is limited in
developing students' practical skills.
Computer-aided
design:
Some
universities
in
Uzbekistan have introduced CAD programs, such as
AutoCAD and SolidWorks, but the teaching process
using these programs can often be less effective than
traditional teaching methods. To be effective in using
the programs, teachers themselves need to learn
advanced technologies and use interactive approaches
in their lessons.
Development of project-based learning: Project-based
learning is gradually expanding in local universities. In
this approach, students work in groups to solve real-
world engineering problems. However, the necessary
infrastructure and teacher training are required for the
widespread implementation of this method.

underway to introduce virtual simulations and
laboratories in local universities, these technologies are
still used to a limited extent. Some large universities in
Uzbekistan are upgrading their software and hardware
to introduce simulations and virtual laboratories, but
this process is still at an early stage.
Comparison between control and experimental groups
using modern methods with students: Experimental
methodology is widely used in scientific research to
obtain real data and test theoretical approaches in
practice. In order to study the effectiveness of using
modern methods in teaching engineering graphics, the
differences between the control and experimental
groups of students were analyzed in the experiment. In
this
experiment,
it
was
determined
what
improvements students achieve by using modern
teaching methods and what differences they show
compared to traditional methods.
The main goal of the experiment is to evaluate the
effectiveness of integrating modern teaching methods
- computer-aided design programs, interactive lessons,
3D modeling and project-based learning - into the
educational process. The following tasks were
accomplished through the experiment:
1. To determine the knowledge and skills of the group
trained using modern methods in engineering graphics.
2. To compare with the group trained using traditional
methods.
3. To analyze the results of both groups and determine
which method is more effective.
Two groups participated in the experiment:
Control group (traditional methods): In this group,
students were taught using traditional methods. In this
method, the teaching was based only on the creation
of technical drawings and basic drafting skills. In this
group, computer-aided design programs and 3D
modeling techniques were not used.
Experimental group (modern methods): In this group,
students received education using modern teaching
methods. In this group, computer-aided design
programs, 3D modeling, interactive simulations, and
project-based teaching methods were introduced.
Duration of the experiment: The experiment was
conducted for two semesters. A specific subject
program was determined for each group and the
educational process was organized based on this
program. Lessons were held twice a week, each lesson
lasted 90 minutes. At the end of the experiment,
practical developments and tests performed by
students were evaluated.
The following methods were used in the experimental
group:
Computer-aided design (CAD): Students were taught to
create technical drawings and design 3D models using
programs such as AutoCAD and SolidWorks. By using
the programs, students had the opportunity to create
not only traditional drawings, but also virtual models of
them, analyze changes, and test how the designs work
in practice.
3D Modeling and Visualization: Using 3D modeling
software (such as Blender or SketchUp), students were
given the opportunity to view and test their designs in
three dimensions. This gave students the opportunity
to make sure that the design was accurate and of high
quality.
Project-based learning: Students were divided into
groups and created practical projects to solve real-
world engineering problems. During the projects,
students developed skills such as teamwork, planning,
task allocation, and technical problem-solving.
Interactive Simulation Using simulation software,
students were given the opportunity to test their
designs under different conditions. For example,
simulations were conducted taking into account the
strength of materials or the effects of heat. [9]
At the end of the experiment, the differences between
students were as follows:
• Control group: Students trained using traditional
methods gained good knowledge in creating technical
drawings, but had difficulties in using 3D modeling and
modern design programs.
• Experimental group: Students trained us
ing modern
methods gained much higher skills in using 3D
modeling and CAD programs. They achieved high
results not only in creating technical drawings, but also
in developing practical projects.
Creativity and critical thinking:
• Control group: Although s
tudents trained using
traditional methods achieved good results in drawing,
they showed limitations in their creative approach,
especially in creating projects in an innovative way.
• Experimental group: Students using modern methods
achieved better results in creative approaches to
projects, applying various technological solutions, and
solving problems in an innovative way.
Teamwork and Collaboration:
• Control Group: While students trained using
traditional methods performed well in teamwork, they
were more likely to work individually and showed
weaknesses in creating innovative solutions in
collaboration.
• Experimental Group: Students trained using modern
methods performed significantly better in working

effectively in teams, making strategic decisions for a
project, and solving team problems.
The results of the experiment showed that modern
teaching methods help students become more
competent, creative and practical. Using CAD
programs, 3D modeling and project-based teaching
methods, students developed effective working skills in
practice. At the same time, modern methods also
encouraged students to work together and create
innovative solutions. The results of this experiment
indicate the need for a wider application of modern
methods in the education system.
CONCLUSION
This study aims to study the effectiveness of using
modern methods in teaching engineering graphics.
During the study, the differences between traditional
teaching methods and modern approaches and the
impact of each method on students' knowledge and
skills were analyzed in depth. As a result, it was found
that the introduction of modern methods into the
educational process has a number of advantages that
provide higher results and efficiency for students.
