For ease of calculation, this study uses a
five-point Likert scale to calculate each dimension
of the evaluation model. Assume that participation
Q=Q1+Q2+Q3+Q4+Q5, each of which counts for 1
point to simplify the calculation;Assuming that the
actual value of the above items is Qi (i=1,2,3,4,5),
the theoretical value is Q'i, n is the number of
parameters, and the total number of people is N,
then the participation can be calculated as follows:
Q=

Q

n=5
(1)
Qi/N is the actual average value of a parameter,
and Qi/(N×Q' i) is the actual value/theoretical value,
that is, the degree of completion of the theoretical
value. If Qi/(Q' i×N)≥1, the value of this item is 1,
and the theoretical goal is achieved ; If Qi/(Q'
i×N)<1, the theoretical goal is not achieved. The
value of n will also increase with the iteration of
THEOL platform, and the formula (1) from this
study can also be applied.
(2) Interaction
Due to the unavailability of data from real-time
interactive classroom, but only network interaction,
this study mainly include the number of reading
teaching materials (J1), the number of class
discussion topic (J2), group discussion area (J3),
according to the number of palindrome course
discussion is palindrome number (J4) and the
number of reading course notice (J5).

Ji/S is the actual average value of a parameter,
and Ji/(N×D 'i) is the actual value/theoretical value,
that is, the degree of completion of the theoretical
value. If Ji/(J 'i ×N)≥1, then the value is 1, and the
theoretical goal is achieved. If Ji/(J' i×N)<1, the
theoretical goal is not achieved.
(3) Adaptability
Since students have different levels of
knowledge and experience, the adaptability of
blended learning will be different. The adaptability
of blended learning mainly examines students’
recognition of the new learning style (R1), task
difficulty (R2), teamwork (R3), re-engagement (R4)
and recommendation index (R5).

Ri/N is the actual average value of a parameter,
and Ri/ (N×R' i) is the actual value/theoretical value,
that is, the degree of completion of the theoretical
value. If Ri/(R 'i ×N)≥1, then the value is 1, which
achieves the theoretical goal. If Ri/(R' i×N)<1, the
theoretical goal is not achieved.
(4) Satisfaction
In distance training, student satisfaction is
usually used to evaluate student response. Trainees’
response to the training theme, online training
course, online tutor, and online training organization
make up the main aspects of online training.
(5) Effect
This study proposes that the effectiveness
evaluation of students’ learning effects of blended
learning mainly includes two parts: ① the
evaluation of students' experimental results is carried
out by combining teachers' evaluation and students'
mutual evaluation; ② The students' mastery of
thematic skills was investigated by questionnaire.

3.2 SVM Algorithm for Evaluating
Teaching
A Quadratic programming will be used to solve the
support vector machine (SVM) algorithm. (Zhang,
Li , and Fu, et al. 2005) In the case of the existing
samples, assuming that ωx + b=0 on the sample
set defines two classes. Which training

and its distance can reach the maximum, then the
