## 1. Introduction

With the rapid development of Taekwondo, new curriculum reforms, and advances in technology, the requirements for Taekwondo teaching are getting higher and higher [1, 2]. Now, Taekwondo teaching still faces some problems: for example, the level of Taekwondo coaches is uneven, lack of innovation ability, outdated teaching methods, and lack of venue facilities [3, 4]. Combining B D A technology is one of the very important ways to innovate the teaching method of Taekwondo in college elective courses [5, 6].In the research on the innovation of Taekwondo teaching methods, many scholars have made good achievements. For example, Junyi believes that Taekwondo theory learning and practical teaching should be emphasized in the teaching process [7, 8]. Bian Wenhong started with the basic connotation of happy physical education. Teachers teach happily, let students learn in a pleasant atmosphere, and cultivate their initiative and creativity [9, 10]. Students learn in a happy, relaxed, and harmonious environment, rather than being forced to accept, so as to cultivate their lifelong awareness of sports [11, 12].The purpose of this article is to promote the development of higher education in our country. The purpose of this article is to conduct innovative research on the Taekwondo teaching methods of college elective courses based on B D A technology. By combining the traditional Taekwondo teaching methods with the Taekwondo teaching of college elective courses based on B D A technology, the methods are compared and analyzed to judge the feasibility of the innovation of the teaching method of Taekwondo as an elective course in colleges and universities under the background of B D A.


## 2. The Application Research of University Elective Course Taekwondo Teaching System Based on Big Data

### 2.1. Background Connotation of B D A

In the context of the information age, with the rise of new media such as digital terminals, cloud services, Weibo, and WeChat, information data is also showing an exponential growth trend. At present, there is no unified definition of B D A, but the academic circles basically believe that it mainly refers to software and hardware tools and data related to the perception, collection, processing, management, and service of the assembly. It has the characteristics of low value density, diversity, scale, and high speed and can be divided into structured data, semistructured data, and unstructured data [13].


### 2.2. Analysis of the Status Quo of Taekwondo Teaching in Colleges and Universities

Our country’s physical education curriculum has always been in a passive state in actual teaching. Many schools’ physical education classes are dominated by herding sheep. It is precisely because school leaders do not pay attention to physical education courses, which has caused some educators in our country to pay no attention to physical education courses. Taekwondo is part of the physical education curriculum, and it has also been ignored by teachers in teaching [14].


### 2.3. Analysis of Taekwondo Teaching Strategies for the Elective Course in Colleges and Universities with B D A Background

#### 2.3.1. Strengthen the Introduction of Full-Time Taekwondo Teachers and the Construction of Teaching Facilities

Teachers are one of the main groups in the entire teaching process. Adding new forces is an important measure to improve the overall level of Taekwondo teachers in colleges and universities. Teaching venues are an important factor that restricts teaching. Taekwondo is a sporting event that requires very high venue facilities. Therefore, the quality of venues and facilities affects the quality of teaching to some extent and limits the development of Taekwondo teaching.


#### 2.3.2. Optimize Teaching Courses

The curriculum setting must be set around the realization of the training goals, and the curriculum setting of the physical education major is the same. The reform of the physical education curriculum is a complex and cumbersome systematic program. It mainly includes several aspects. One is the reform of the curriculum content. The second is to optimize the curriculum structure. Optimizing the curriculum is a necessary condition for students to form a reasonable ability structure.


#### 2.3.3. Standardize Examination Standards, Etc.

Students’ learning results can be reflected in test scores. Therefore, the test must be standardized. The test format can be diversified. A unified test standard can be formulated so that students can truly learn everything in the Taekwondo class. The courses are all for the sake of class. After the class is over, the content learned is also forgotten. After the Taekwondo course is completed, students should be able to take classes in elementary and middle schools or in a Taekwondo club. This is the purpose of setting up a Taekwondo course, which is also conducive to the future employment of students. It is more conducive to the development of school sports and national fitness.


### 2.4. Design of Taekwondo Teaching System for College Elective Course Based on D M I

#### 2.4.1. DMI Technology

The DMI process actually refers to using algorithms or rules to obtain hidden information from large amounts of data that can be achieved by various methods such as machine learning, mathematical analysis, and professional structure. WEB mining was developed by DMI and supports algorithms such as database techniques, classification, and clustering. If users of large websites are processing large datasets, multiple processors need to use parallel computing techniques to perform distributed processing.


#### 2.4.2. System Feasibility and Demand Analysis

(1) Feasibility Analysis. Nowadays, there are many kinds of learning resources on the Internet, and ordinary face-to-face classrooms cannot meet the learning needs of students for all kinds of knowledge. Currently on the Internet, new forms such as video courses such as microclasses are emerging in an endless stream. The curriculum resources are abundant but huge, and students cannot quickly find materials that suit them. In addition, the university elective course Taekwondo teaching lacks theoretical knowledge teaching, which requires the school to establish a resource database for the students of the school, so that students can choose appropriate teaching resources according to their own conditions and needs. Therefore, it is necessary to establish a system that can help students learn online and provide related services. The research of this project is to develop the university elective course Taekwondo teaching system based on D M I with the support of university campus network.(2) Demand Analysis. The network-based network teaching system is aimed at three types of users: system administrators, network teachers, and students participating in online teaching. Teachers mainly need to lecture on the Internet platform, answer questions, take exams, review test papers, and evaluate teaching. For students, they also need to evaluate the teacher’s teaching effectiveness. Therefore, the main task of the system is as follows: the system administrator uses the administrator account to manage the platform and is responsible for assigning specific user permissions and resources to users, so as to realize the allocation of teaching resources and the authorization of user functions. Teachers are responsible for the resource and authority settings of online courses, such as online courses, assignments, online questions, and test evaluations.. Teacher accounts can be used to generate course resources, manage the classroom right to participate, implement online teaching, online work management, online Q and A, etc., and the purpose of evaluating and evaluating the students’ performance. Students are responsible for attending classes, taking exams, taking questions, using the student account to obtain course applications, asking questions, and completing course assessments during the study process.


#### 2.4.3. Overall System Design

The university Taekwondo teaching system based on B D A allows students to use the self-test platform provided by the system to understand the mastery of theoretical knowledge in time and participate in the course of the course in time.(1) Detailed Design of Online Course Modules. The online course module is mainly to display the course title of the course on the homepage. When you log in to the detailed interface, there is a detailed introduction of the fine course such as pictures. At the same time, both the administrator and the teacher can maintain the course. When the administrator or teacher adds a course, find out whether there is corresponding course information. If not, create the course.(2) Database Design. The design structure of course schedule is shown in Table 1.Table 1

It uses the int type and is the primary key of the table. It cannot be empty. Auto_increment is the realization of automatic growth.


### 2.5. Application of Collaborative Filtering Algorithm in Teaching Resource Recommendation

When a user A needs personalized recommendation, you can first find a user group G similar to his interest and then recommend what G likes and A has not heard of to A, which is the user-based system filtering algorithm.Pearson coefficient is a similarity calculation method based on correlation coefficient. It needs to find the common score of the users in order to make accurate calculation results.U is the set of users who rated item i and item j, and the Pearson correlation coefficient formula is as follows:
(1)simi,j=∑u∈URu,i−Ri¯Ru,j−Rj¯∑u∈URu.i−Ri¯2∑u∈URu.j−Rj¯2.Among them,Ru,i is the rating of user i on item j, and Ri is the rating of item set U on the same item.The implementation of collaborative filtering recommendation system relies on user ratings and other behaviors; so, it is a good idea to use clustering methods to divide the population into several categories. This paper intends to introduce a hybrid algorithm based on the combination of clustering algorithm and collaborative filtering algorithm to solve the problems in recommendation, increase recommendation efficiency, and increase recommendation quality. The algorithm is as follows:(2)simu1,u2=1−∑u∈Uru1,i−ru2,i2commonItems.

## 5. Conclusion

As a kind of educational practice activity, the realization degree and implementation effect depends on the science and modernity of methods and means. Only in the face of the new changes in the situation and tasks brought about by technological progress and technological innovation can the innovative teaching methods of Taekwondo make the Taekwondo teaching more attractive and full of new vitality. Today, BDA technology has changed the teaching model that has lasted for thousands of years. Taekwondo teaching should also stand at the forefront of the BDA era, keenly perceive the more convenient, efficient, and personalized teaching methods brought by BDA, have an indepth understanding of the innovation of teaching thinking caused by BDA, and actively choose to cooperate with BDA. The integration of data will raise the improvement of Taekwondo teaching methods to a new level. Experimental research shows that compared with traditional Taekwondo teaching methods, the performance of university Taekwondo teaching based on data mining (D M I) in the context of B D A is more than 20% higher, which fully reflects its feasibility and the innovation of traditional Taekwondo teaching methods needs to be solved urgently.
