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.
