Abstract: With the continuous development of science and technology and the normalization of epidemic prevention
and control, online learning is becoming more and more popular. Practice has proved that online teaching
can make college education more effective. Therefore, using modern information technology and online
high-quality educational resources, the author of this paper has constructed an online teaching system of
economics based on MOOC. This system uses C# language for overall development, introduces ASP.NET
framework for process building, and combines SQLsever database technology to set up two landing roles of
students and teachers, so as to build an equal and open platform for the communication between teachers
and students, and promote the common learning and progress of college teachers and students. It also
provides a new model for economics education in colleges and universities, effectively improves students'
learning interest and efficiency, and contributes to the cultivation of economic construction talents that meet
social requirements.

1 INTRODUCTION
Since the 18th National Congress of the Communist
Party of China, China's economy has entered a new
period of high-quality development from high-speed
development. The change of development mode has
put forward higher requirements for technological
renewal, policy reform and talent iteration, among
which talent cultivation is the most important. As an
important scene of talent cultivation in colleges and
universities, it is necessary to carry out teaching
reform according to the changing economic situation
and policies. In the teaching of colleges and
universities, economics is a very important course,
shouldering the important task of cultivating
economic construction professionals. But at present,
there are still many problems in economics
education in colleges and universities, for example,
the update of teaching content is lagging behind, the
teaching mode is single, the construction of teachers
is backward, personalized education is ignored, and
knowledge is valued over practice. If we continue to
use the traditional teaching method of "classroom-
centered, textbook-centered and teacher-centered",
not only will the teaching work be ineffective, but it
can't effectively match the needs of social posts,
resulting in the disconnection between production
and learning. So, colleges and universities began to
actively carry out curriculum reform, including
information-based teaching. Since 2011, three online
teaching platforms, Coursera, Udacity and edX, have
emerged. MOOC (massive open online courses), a
large-scale open online course, has attracted people's
attention, especially under the background of
normalization of epidemic prevention and control.
The Mooc of China's universities, Love Courses,
Good University Online, School Online, Wanmen
University, etc. have been launched one after
another. After a period of practice, it has been
proved that MOOC provides a new teaching mode
for college education, which makes learning scenes
break through the time and space constraints,
realizes the high integration and optimization of
teaching resources, cultivates high-level teachers,
maximizes classroom interaction, highlights
students' dominant position in learning, and realizes
personalized education with big data cloud
computing. Therefore, the establishment of MOOC-
based "online+offline" hybrid teaching has become

one of the important efforts of current college
teaching reform.
According to the above analysis of various
problems in the current teaching situation of
economics in colleges and universities, the author of
this paper thinks that we should actively seek online
teaching schemes, develop an online teaching
system of economics based on MOOC, use C#
language for overall development, introduce
ASP.NET framework for process building, and
combine SQLsever database technology to build an
online teaching system of economics in colleges and
universities with rich resources and powerful
functions.This system can effectively solve many
problems existing in economics teaching in colleges
and universities, promote the informatization
process of economics teaching, and help to send
more high-quality talents to the country and promote
the development of China's economic construction.
2 KEY TECHNOLOGIES
2.1 Web
The Web is a distributed graphic information system
based on the Internet, which transforms the
information in the Internet into a visual and readable
interface. All technologies that support Web
operation are collectively referred to as Web
technologies. There are five elements of Web
technology: identification mechanism (such as
URL), transmission protocol (such as HTTP and
HTTPS), data format (such as HTML, XML, JSON),
Web browser and Web server. These elements are
divided into two categories according to their
functional attributes, namely client-side technology
and server-side technology. (Chen, 2019)
2.2 C#
The C# inherits the powerful programming ability of
C and C++, and at the same time abandons many
complicated and useless functions. It has unique
advantages: cross-platform use (Windows, MacOS
and Linux), complete open source (runtime, library,
compiler, language and tools), compatibility
(compatibility with. net Framework, Xamarin and
Mono through. NET standard library), etc. It runs
on. net Framework and. net Core, and becomes the
preferred language for. NET development. (Tian,
2016)
2.3 ASP.Net
The ASP.net technology is developed from ASP
technology, and it is a research and development
method based on Web. The foundation of ASP.net is
based on space and task-driven. The ASP dynamic
server page, whose full name is Active Server Pages
and Chinese name is Active Server Page. The
development mode of ASP.net includes
ASP.netWeb Form, ASP.net MVC, ASP.netCore,
etc. Developers can choose the development mode
according to their own technical background and
specific needs. The working principle is shown in
Figure 1. (Tang, 2022)

2.4 SQL Server
The SQL Server is a kind of relational database
management system, which is widely used. Its
advantages mainly lie in its scalability (applicable to
various platforms, providing rich interfaces),
integration (providing the function of data
warehouse, and being closely related to many server
softwares), ease of use (graphical interface, more
intuitive and concise), and high efficiency (reducing
the time and cost for users to manage data). By using
this database, users can easily publish the required
information and data on the Web, and users can
view the data stored in SQL Server through common
browsers. (Tang, 2018)
2.5 Development Process
According to the requirements of the above and
related technologies, complete the configuration and
deployment of the development environment of
online teaching system of economics in colleges and
universities. The system is written in C# language,
with Windows10.0 as the operating system, IIS10.0
as the Web server, Visual Studio 2019 as the bottom
development tool and SQL Server2019 as the
database server.
First of all, configure the development
environment for ASP.net, including the download
and installation of IIS server, SQL Server database
and VS2019. After the development environment is
ready, click Visual Studio 2019 and select "Create
New Project", and then select "Asp .Net Core Web
Application" in the pop-up window. The new project
is named "Economics Online Teaching System", and
the framework "ASP.net Core 3.0" is selected to
create a "Web application". Then, right-click the
Solution "Add" New Project ", select the class
library (.NET Standard), create a general class
library named Common, and then add a
CommonHelper class that can be called directly. In
the "Online Teaching System of Economics" project,
add a reference to the class library, call the static
method under the HomeController of the "Online
Teaching System of Economics" project, modify the
data rendered on the Privacy page, select Kestrel
mode and click Run. After that, we successfully
designed the functions of each layer, and the specific
functional modules are shown in Figure 2. After all
the functional modules of the system are designed
and implemented, a simulation test will be
conducted. After the test is correct, all system files
will be packaged and released, and deployed in IIS
server. After the IP address is set, it can be used by
all platform users.
With the introduction of the above key
technologies and theories, the overall framework
process of platform development is determined, and
the feasibility of establishing and running the online
teaching system of economics in colleges and
universities is clarified.

3 FUNCTION REALIZATION
3.1 Student Side
The students click to enter the online teaching
system of economics, and click to enter the "Student
Portal" to register and log in. After logging in, they
will see the following two sections, "Autonomous
Learning" and "Social Practice". The specific
functional modules are as follows:
NMDME 2022 - The International Conference on New Media Development and Modernized Education
330
3.1.1 Autonomous Learning
As long as "autonomous learning" is exerted from
the two stages of "before class" and "after class", it
will complement the traditional classroom teaching,
manage each part carefully and enlarge the teaching
effect.
In the "before class" section, there are mainly
two preview methods: "online library" and "video
open class". In the "online library", students can
view other electronic textbooks, supplement the
textbooks ordered by the school, and borrow other
related books. The system integrates a large number
of authoritative teaching materials and e-book
resources, and updates them in real time according
to the economic situation and policy changes. In the
"Video Open Class", a wealth of video courses of
famous teachers have been collected systematically,
such as Tsinghua University's Principles of
Economics, Xiamen University's Network
Economics and other series of courses. There are
also front-line teachers' own explanation videos and
live classes in our school. Students can make an
appointment for live classes and receive the
countdown notice. During the class, they can send
barrage for real-time communication and interaction.
The live class is mainly implemented by Asp.Net
Core+Dapper+SQL Server, and some codes are
shown in Figure 3. (Zhang, 2022)
Figure 3: Live lesson implementation part of the code
After class, students can see three options: self-
examination and self-test, online question and
answer and study data. The students can choose the
corresponding question bank of the course of study
in "self-examination and self-test". Each question is
randomly generated, including objective questions
and subjective questions. After the answer is
finished, the system will automatically give the
scores, answers and analysis of the subjective
questions, and the objective questions will be
uploaded to the teacher for review. The "Online
Q&A" has established an open platform for effective
communication between students and teachers. In
this module, students will see all the teachers of
economics and related majors who have settled in
the platform, and they can not only consult their own
professional teachers, but also ask other teachers
questions about economics. Teachers and students
can discuss and study together. The "learning data"
is a system that forms a visual report according to
students' performance in preview before class and
homework after class, including outstanding aspects,
areas still lacking, areas of interest, etc. The purpose
of helping students is to plan their learning time.
3.1.2 Social Practice
The "social practice" is mainly aimed at the problem
that the traditional teaching mode emphasizes
knowledge over practice, as long as the pre-work
and follow-up work of practice are transferred
online. In the "practical project", there are practical
activities initiated by teachers, and there are also
practical activities organized by students
spontaneously. The students can check the
information of practical activities, including time,
place, main work contents and requirements for
submitting practical reports, etc. Students can
choose to join practical activities, and then they can
communicate and exchange practical experiences in
the activity group. In the "Time Report", students
can submit practice reports in the form of words,
such as practice reports, practical experiences, etc.,
or pictures or videos, such as activity photo
collections, activity flash videos, etc. By publishing
the practice report online, the individual learning
results can be turned into collective wisdom.

3.2 Teacher Side
The teacher clicks into the online teaching system of
economics, and clicks into the "Teacher's Entrance"
to register and log in. After logging in, you will see
the following two sections, "Teaching Management"
and "Scientific Research and Further Education".
The specific functional modules are as follows:
3.2.1 Teaching Management
In the "Teaching Management" section, teachers are
no longer leaders of learning activities, but guides.
Before class, teachers' main task is to upload
teaching videos or launch live broadcasts, and issue
notices to guide students to preview before class.
After class, the teacher needs to edit the questions
and upload them to the system, and the system will
automatically scramble the questions to generate the
question bank. One test paper can be composed of
several different questions, and the same question
can exist in several different test papers. The code of
the question bank is shown in Figure 4. In the
"online question answering", teachers can give
targeted answers to students' questions or initiate
open topic discussions. We can check the "learning
data" of each student, conduct one-to-one
communication teaching according to the specific
situation of students, reflect on the problems existing
in teaching activities, and adjust the teaching mode.
(Gu, 2022)

3.2.2 Advanced Scientific Research
The module of "further study in scientific research"
is mainly aimed at improving teachers' personal
level, starting from improving teachers' teaching
quality to improve students' learning quality. In the
"scientific research activities", teachers can choose
to participate in all kinds of scientific research
activities inside and outside the school. After the
activities are finished, they need to submit
corresponding reports in the "scientific research
achievements". The reports can be seen by all
teachers in the school, which can provide experience
for other teachers and help to build a higher-level
and constantly improving team of economics
teachers. (Dong, 2019)
4 CONCLUSIONS
The online teaching system of economics can
complement the traditional classroom teaching of
economics in colleges and universities, and form a
flexible and efficient teaching system of
"online+offline". It can help college students grasp
the opportunity of offline practice to exercise their
skills while mastering professional knowledge. It is
helpful for students and teachers to make progress
together, improve the teaching effect of economics
teaching in colleges and universities, and inject
power into China's economic development. In the
future exploration and research, we will continue to
deepen the reform of online teaching system of
economics, let online learning of economics exert
greater influence, cultivate more professionals with

solid professional knowledge and excellent
professional skills, and make contributions to the
sustained and healthy development of China's
economy.
