Firstly, computer is equipped with network
search function under computer network
environment, thus many problems in classrooms can
be solved through the search of network
environment. Thus, teacher's words and explanation
can be substituted by visual presentation. For
example, in explaining the mechanics of stress
analysis, stress effect analysis is relatively abstract
which cannot be explained by rational speech.
Despite of good skills of teachers, students cannot
learn the true meaning of its contents. Therefore, the
presentation functionality of computer networks can
be used to make abstract issues concrete. Stress
analysis can be made in flash animation on display,
thus directly bringing visual impact for students,
which is easier for students’ understanding.
Secondly, visual performance is achieved
through the rendering and stimulation of senses. In
some literary subjects, many contents are vivid.
However, the vivid picture cannot be truly reflected
just by reading the text or the teacher's explanations.
Therefore, the use of video teaching mode under
network environment allows students to directly
experience the described screen of text. This visual
teaching and visual impact, with a sound teaching
atmosphere, makes students feel shocked in visual
sense at first impression, thus realizing actual video
teaching mode.
Finally, the manifestation of visual effectiveness
makes students become interested in teaching
content. Interest teaching is the largest deficiency of
traditional teaching—students’ only purpose in
learning is to get scores. However, capacity is the
most important rather than scores, thus students
should be promoted to have learning motivation and
interest. Traditional teaching mode is boring and
tedious without interest. In contrast, the teaching
mode under computer network environment can
perfectly solve this problem. Visual impact is the
most direct and intense in all senses. Students'
interest in learning can be enhanced through the
visual teaching model under computer network
environment, thus achieving the purpose of efficient
learning through direct teaching model. Therefore,
the implementation of visual efficiency makes
students get rid of traditional teaching haze and have
learning in the enormous visual impact, thus
achieving efficiency of classroom teaching.
4.2 Auditory Effects under Computer
Network Environment
In traditional teaching, teachers' voice will directly
affect the students' interest in learning and its
efficiency. However, their tones are difficult to be
corrected, thus students have to accept it no matter
students love it or not. Therefore, students have no
choice in many cases, resulting in a relatively default
mode of teaching. Actually, the teaching mode can
be fully changed through the reform under computer
network environment. As the second human sense,
auditory sense largely determines the ability to
accept new things. Under computer network
environment, audio-style teaching can be used in
classroom. The needed tone and voice can be
searched through computer network, allowing
students to learn in timbre and sound within the
range of adaptation. Voice teaching should be
properly applied in the classroom teaching under
computer network environment, making students’
auditory sense join the learning activities, thus
improving the efficiency of teaching.
4.3 Communication Effects under
Computer Network Environment
The largest defect of traditional teaching model is
the strong subjectivity of teachers in classroom.
Originally for formal teaching mode, teacher's role is
a guider rather than the subject. However, the status
of teachers in teaching becomes higher in the exam-
oriented education with indoctrination. They allow
students to pursue scores and acquire knowledge as
soon as possible, thus students were turned into
passive receivers. The biggest drawback of this
teaching method is that students have no space for
thinking. Students lack learning enthusiasm due to
teachers' indoctrination explanation and the lack of
interaction opportunity. Therefore, teaching has
become indoctrination and passive receiving, which
completely violates the original purpose of
education. For teaching classroom under computer
network environment, this model can be
fundamentally improved. Exchanges and interaction
are essential for students in learning process.
Therefore, students should be provided with
opportunity for exchange and interaction under
computer network environment, creating lively
atmosphere for their learning, making the learning
much more interesting. This is exactly the efficiency
demonstration under computer network
environment. Actually, classroom teaching under
computer network environment will be more
effective, better achieving quality and efficiency of
teaching.
