training. The American survey report and the
empirical research on classroom teaching, network
teaching and mixed teaching carried out in the training
field, basic education, higher education and public
institution training show that mixed teaching has great
advantages. The president of the University of
Pennsylvania also pointed out that blended learning is
the most important development trend of higher
education. Neither classroom teaching nor online self-
study can achieve the desired results.
Mixed teaching refers to a strategy that combines
face-to-face teaching, online learning and practice
under the guidance of various learning theories and
under the guidance of teaching objectives, according
to the learning content, learning environment,
teaching methods, learners and teachers' own
conditions. It effectively integrates face-to-face
teaching and online learning, and comprehensively
uses online learning to reduce costs and improve
efficiency.
Mixed teaching is a new trend in the development
of international educational technology. That is,
combine the advantages of traditional face-to-face
teaching and online E-learning, and build a large
number of online learning videos for students to learn
independently with the help of a highly interactive
online learning platform; At the same time, through
face-to-face classroom interactive discussion, students
can answer questions and solve doubts, and cultivate
students' comprehensive ability (Lu 2010)

2.1 Research Status of Hybrid
Teaching Mode Based on VR
Simulation Technology Abroad
Since the first e-learning paper published in the
American Training Journal in 1996, educational
technicians and training workers have begun to study
online learning and training, and gradually established
a theoretical system on e-learning. However,
according to the report of the American Society for
Training & Development in 2001, 80% of enterprise
training is still in the form of traditional classroom
teaching, and the development of e-learning is not
ideal. With this report as a sign, e-learning has
gradually entered a low tide. People begin to reflect on
learning in the technological environment. Blended
learning, which combines online and offline learning,
has gradually entered people's vision. With the
deepening of research in the past ten years, mixed
teaching abroad has now been widely recognized and
on the right track. The theoretical research on mixed
learning has become more mature and has been widely
used in foreign universities and enterprises.
Many professors in American colleges and
universities have started to use blended learning. They
use blended learning mode for one or two classes in
the weekly course. They let learners go online for self-
study in dormitories or libraries, and cultivate learners'
ability to acquire knowledge, analyze and solve
problems, and innovate. Through the mixed learning
practice, it is found that the participation of learners
has increased, the team cooperation has become more
harmonious, and the form of traditional classroom
teaching has changed. It is no longer just a teacher's
lecture, but more a place for dialogue and interaction
between teachers and students. In addition, it has also
promoted teachers' cross campus cooperation. By
referencing learning resources with teachers from
other schools, the curriculum content has become
more professional and diversified (S. S. Fisher, M.
McGreevy, J. Humphries, W. Robinett, 1987).
It is verified that there are many theoretical and
practical researches on the research of mixed teaching
mode based on information technology abroad.
However, although VR technology appeared earlier,
the VR technology and supporting equipment really
matured later. The application accumulation period of
VR technology and equipment came in 2016, and
various technical equipment made sudden advances.
This year's application technology burst, which is
called the first year of VR application. Separate VR
simulation technology and hybrid teaching mode have
been studied more abroad, but the research on the
integration of VR simulation technology and hybrid
teaching practice mode is less.
2.2 Research Status of Hybrid
Teaching Mode Based on VR
Simulation Technology in China
In 2003, Professor Zhu Zhiting's paper "Hybrid
Learning in Distance Education" systematically
introduced hybrid learning for the first time in China.
Over the past ten years, blended learning has gained
increasing popularity in China, and its research has
spread throughout school education, in-service
training, adult education and other levels and fields.
From the source of researchers, because mixed
learning research requires a large amount of capital
injection and advanced technical support, as well as
the operation of academic groups with rich academic
background, most researchers come from the central
and eastern regions with developed economy and
higher education, especially in the Yangtze River
Delta, Pearl River Delta, Beijing Tianjin, Wuhan and
other surrounding areas where universities gather.
