progress and control video time, and their teaching
methods can be carried out according to teachers'
"personalization", so as to attract students' attention
and preview effectively. Classroom stage: In the flip
classroom teaching, teachers get rid of the usual basic
knowledge teaching, answer the difficulties and
questions that students feedback before class and ask
questions about students' basic knowledge (Jin,
2017). "Share, set top, edit". Class groups can help
teachers to form different groups of students
according to their situation, and implement
hierarchical teaching. Students learn in class groups,
and teachers grade and evaluate in class groups.
Teachers can check students' reading, interaction
and scores in performance statistics. Starting from the
needs of students' oral English learning, the arranged
teaching contents, tools and methods should be
conducive to the cultivation and promotion of
students' ability. Teachers can check students'
reading, interaction and scores in performance
statistics. Besides daily interactive discussions and
comments, teachers can also use the class group
function to issue tests and exams, and evaluate and
grade all students. Of course, teachers should perform
their duties and evaluate students' preview before
class, learning attitude and implementation of
activities. This kind of teaching evaluation mode can
not only promote students to be positive, but also
innovate teaching methods.
2.3 Starting from Teaching Resources
Teachers and students actively interact with each
other and provide guidance to learning groups that are
lagging behind. Through communication and
understanding, teachers and students can narrow the
gap between teachers and students, improve students'
learning interest, thinking innovation and practical
application ability, and lay a foundation for future
social life. In the age of big data, traditional teaching
methods can no longer meet the needs of college
English teaching. Digital technology is increasingly
used in teaching. Digital English teaching is
becoming more and more mature. It is inevitable for
teachers to change teaching methods and master
digital teaching methods. Teachers make micro
lesson videos before class of intelligent online
courses, control teaching objectives in many aspects,
enrich teaching content, and ensure that teaching
videos can also attract students in an unattended
environment (Liu, Chen, et al. 2020). Through
learning micro lesson videos, students can grasp the
practice time independently and watch the
fragmented learning repeatedly. In the era of big data,
college English teachers can make full use of online
education resources for intelligent oral English online
course teaching, especially when correcting students'
oral pronunciation, teachers can use pre collected
pronunciation skills, oral improvement cases, etc. to
improve classroom teaching efficiency.
Use intelligent online courses to carry out English
teaching, analyze the learning data of all online
students in general, and master the learning
characteristics of the overall students. At the same
time, the continuous learning data of each student is
analyzed to understand the learning situation of each
student. Students can practice following the assigned
dubbing clips before class, and use the software's own
functions such as verification of phonetic symbols,
original voice following, system scoring, and netizen
interaction to stimulate students' interest in practice.
Teachers can collect students' dubbing clips and
analyze voice problems, and give one-to-one
guidance on correcting sounds in class.
3 ANALYSIS AND DISCUSSION
3.1 Adhere to the "Student-Centered"
Teaching Philosophy
In the online course research of college oral English
intelligence based on big data analysis, we should
adhere to the "student-centered" teaching concept.
According to the data analysis of students' online
spoken English teaching, the following adjustments
are made in the follow-up online spoken English
teaching strategies: First, because the pronunciation
and intonation of words are the basis of learning
spoken English, we should increase the learning
content of words' pronunciation and intonation,
especially the practice of vowel pronunciation and
vivid intonation, and guide students to learn from
some movies and videos with standard pronunciation.
Online oral English teaching is "student-centered".
Teachers can analyze and mine the overall teaching
data of students, and then adjust teaching strategies
according to the results. Teaching objectives are
sometimes difficult to achieve, not necessarily
because of students' intelligence, but to a large extent
because teachers' teaching methods do not respect
students' cognitive development laws and cannot
arouse students' inner resonance.
Make full use of online teaching tools, for
example, uploading oral English test or oral English
training resources in the oral English learning
platform, requiring students to complete the test and
training tasks as required, and monitoring students'
