Practical Application of Network Multimedia Courseware in College Basketball Teaching

: With the continuous development of my country's sports industry, many drawbacks have appeared in traditional basketball teaching. This research mainly discusses the practical application of network multimedia courseware in college basketball teaching. Multimedia courseware teaching plan Multimedia courseware teaching plan consists of at least four parts: teaching content, teacher guidance, student learning and multimedia courseware. In the example of this study, FlashMX2004 is used to complete the multimedia courseware of basketball tactics basic teaching. The whole courseware is easy to embed in the webpage and is suitable for wireless network transmission on the Internet. Use the scanner to scan the text part into the computer, recognize it with Hanwang HWOCR5.0 recognition software, and edit it in Word. Use the video processor and audio processor of Kingsoft Hasee II to convert the VCD to the .avi video file format, use Windowsmoviemaker to edit and integrate the edited film, and finally import the required materials into Flash as needed to make the courseware . In order to ensure the correctness and effectiveness of the basic actions in the courseware, the empirical validity evaluation method is adopted, and the validity of the courseware content is tested. After the teaching experiment, in order to test the basic knowledge of basketball tactics and the theoretical knowledge of the two groups of students, a test of the theoretical knowledge of basketball tactics was carried out. The experimental group had 22 people with a score of 90 or more accounted for 27.5%, and the control group had 13 people with a score of 90 or more accounted for 16.5%. The results show that multimedia computer-assisted teaching has a positive role in cultivating students' interest in learning.

Network multimedia courseware has many unique functions, which can also be applied in sports teaching, combined with the teaching of sports skills and tactics training.Basketball teaching is mainly the teaching of skills and tactics.The abstractness of teachers' oral explanation, the limitation of demonstration actions and the complexity of tactics make the teaching of technical actions and tactics become the key and difficult points of basketball teaching, and the emergence of basketball animation effectively solves these problems.Under the effect of network multimedia courseware teaching, the more difficult obstacles of abstract thinking, language expression and logical thinking can be easily resolved, which can fully mobilize students' learning enthusiasm, guide students' interest in thinking and exploration, thus creating a learning atmosphere of learning happily.
Multimedia has affected many areas of education.Sidhu MS proposed an effective conceptual courseware development model, specifically for children with reading disabilities.He identified five basic functions to support the model, namely interaction, activity, background color customization, text reading (left and right) recognition and detailed description.He developed a prototype courseware based on the suggested model and tested it with a small group of children with dyslexia from selected schools in Malaysia.His research sample is too small [1].In response to the growing importance of online education in social work education, Alston ST introduced the background of online teaching in social work education.In the context of the historic black university (HBCU), online teaching was further discussed.He emphasized the importance and necessity of well-trained teachers teaching in an online environment (especially in HBCU).He provided an example of how HBCU University of the District of Columbia prepares its faculty and staff to teach online, and use online teaching and social work the teacher's specific strategy ends.His research lacks comparative data [2].Luo T believes that as more and more K-12 students study online in full-time online schools and blended learning environments, universities must prepare future educators for them in a virtual environment including clinical practice conduct teaching.Before engaging in online site placement, pre-service teachers must face online K-12 teaching.He used a design-based hybrid approach research method and sampled samples from four parts of the hybrid technology integration course.The method he proposed is not rigorous [3].Rhode J believes that many institutions have adopted a universal method to develop online teaching teachers, which cannot meet the needs of teachers who often have different experience, skills and self-efficacy levels in online teaching.In order to solve these problems, he designed and implemented an online teaching readiness self-assessment.The tool is developed based on the key attributes and skills required for online teaching proficiency, covering three areas: online teaching experience and attitude, learning management system proficiency, and access to technology.The self-assessment was distributed through a web-based survey tool to teachers who were determined to develop new online courses.The individual results are used to create a personalized framework for professional development products (workshops, institutes, videos, and consulting) and provide timely resources to support the teacher's development process.His research has no practical value [4].This research mainly discusses the practical application of network multimedia courseware in college basketball teaching.In the example of this research, FlashMX2004 is used to complete the multimedia courseware of basketball tactics basic teaching.The whole courseware is easy to embed in the webpage and suitable for transmission on the Internet.Use the scanner to scan the text part into the computer, recognize it with Hanwang HWOCR5.0 recognition software, and edit it in Word.Use the video processor and audio processor that comes with Kingsoft Hasee II to convert the VCD to the .avivideo file format, use Windowsmoviemaker to edit and integrate the edited film, and finally import the required materials into Flash as needed to make the courseware.In order to ensure the correctness and effectiveness of the basic actions in the courseware, the empirical validity evaluation method is adopted, and the validity of the courseware content is tested.

Application of Network Multimedia Courseware in Physical Education
The first is to break through the time and space limitations of conventional classrooms and create better teaching scenarios [5][6].Make full use of modern computer multimedia technology to create a teaching scene based on multiple sensory stimulations such as sound, image, animation, text, etc.
Students understand the action structure in detail, form a complete action representation, and maximize the teaching effect [7].The second is to reduce the complexity of theoretical knowledge to stimulate students' interest and achieve long-term memory effects [8][9]."Interest is the best teacher", multimedia computer can create a positive and happy emotion.Through the strong expressive power of the pictures, sounds and texts of multimedia courseware, students are actively willing to learn in this emotion [10] .
Overcoming the boring content of books, turning some "dead" theoretical knowledge into "living", simplifying the complexity, increasing the interest of the knowledge, the students' attention is more concentrated, and the thinking is naturally active [11][12].The use of multimedia technology can optimize the physical education teaching process, impart high-density knowledge, break through teaching difficulties, and use the powerful graphics processing functions of computers to weaken or eliminate the learning obstacles of abstract thinking and language expression [13].Sports theory knowledge can be made into vivid curriculum software, so that students can complete the mastery of knowledge even after class (zero class hours) [14][15].Increase the capacity of knowledge so that students can better master the content they have learned.Moreover, the expressive means of pictures, sounds and texts are more conducive to students' long-term memory of knowledge and receive teaching effects that can not be matched by conventional classroom teaching [16].

Basketball Shooting
The knowledge of human movement development characteristics can help physical education teachers to understand the typical characteristics of students' movement skill development levels at various ages [17][18].For example, use the "whole sequence" to describe the general characteristics that appear on most students' bodies, or use the "partial sequence" to discover the special characteristics of a few students on the legs or other specific parts of the body, and then in physical education, according to The level or characteristics of its physical movement development determines what kind of physical education content to choose, and then the improvement of human motor skills changes with age and the level of physical education [19].
(1) Assuming that the basketball touches the backboard or the size of the basket after the ball is shot [20][21].Therefore, according to Newton's law, the equation at time t is: Among them, g is the acceleration of gravity [22].From this, the trajectory of the center of the ball can be obtained as the following parabola: get the condition that the ball hits the center of the basket: In addition: It can be solved for 1 It can be seen that min v is the decreasing function of h [23-24].The incident angle ψ when the ball enters the basket can be obtained from the following formula: L 2 -tan tanψ h H (7) Through the above analysis, we can get the relationship between shooting angle, speed and basket angle of different shooting heights in case 1 [25].
(2) Suppose that the basketball hitting the backboard is not considered after the hand is obtained, but the size of the basket is considered.Suppose the diameter d of the basketball and the diameter D of the basket.

D d sin (8)
When the ball enters the frame, the center of the ball can deviate from the center of the frame, and the maximum distance forward is x , then: Similarly, seek guidance on 1 v and make L = x , then: cos sin (13) The relative deviation of 1 v can be obtained as: x (14) In this case, the pitch angle can be obtained as:

Courseware Design
Making a multimedia courseware needs to start from the textbook and instructional design, collect and create all kinds of materials needed in it, and then make and debug and run [26].It is especially necessary for an ordinary teacher to understand and master the methods of software engineering.
According to the life cycle method of software engineering, the whole system consists of 5 parts.The courseware design process is shown in Figure 1.
(1) Overall scheme design Before developing a multimedia courseware, we should first analyze the overall needs of the courseware, the goals achieved by the courseware and the material conditions needed to make the courseware, determine the development time, testing and actual application time, which is called demand analysis.After that, the overall plan design of the courseware was made.The purpose of the overall plan design is to determine whether the educational thought can be realized with the corresponding computer technology [27].
(2) Script design of courseware After in-depth study of the syllabus and clarification of the teaching content, the curriculum is divided into several knowledge points.Select the development tool, the media material format used for each knowledge, and write the result of the courseware design into a courseware script.
(3) Courseware production After the script is designed, start to make the courseware, the steps are as follows: ①Select and design materials.
② Make multimedia courseware.③Online publication of multimedia courseware.
(4) Test evaluation Courseware evaluation basically proposes the basic content and main indicators of the courseware from the aspects of information presentation, human-computer interaction, teaching process control, and document provision. (

5) Promotion and application
The promotion and use of courseware is very important.Unused or small-scale use of courseware that consumes a lot of manpower development is undoubtedly a huge waste of manpower and financial resources.Therefore, a well-made courseware should be promoted and issued in time Let more people benefit.Therefore, before the courseware is developed, the preliminary document design of the courseware must be done well.During the courseware development period, we must spend more time for mid-term production.In the later stage of courseware development, the operation, testing and modification are repeated cycles of analysis, design, development, and operation.

System Design
(1) The specific formulation of teaching objectives.According to demand analysis, the predetermined teaching objectives are refined.According to the attributes of each knowledge point (facts, concepts, principles, technical characteristics, problem solving, etc.), list the levels.
(2) The choice of teaching strategies.According to the teaching objectives of the course, use this courseware as a part of auxiliary teaching.
( teaching method and learning method, ending part, exercise load estimation, venue equipment, and afterschool summary.②The multimedia courseware teaching plan of "Basketball Tactics Basic Cooperation" The multimedia courseware teaching plan consists of at least four parts: teaching content, teacher guidance, student learning and multimedia courseware.Multimedia courseware is only a part of the whole teaching process, and the interaction and interaction of these four parts should be fully considered.

Teaching Plan of Multimedia Courseware
(1) Introduction The teacher points out the key points and difficulties of this course, students have a preliminary understanding of this course, and the multimedia courseware displays the entire content catalog of this course.
(2) Each chapter The teacher explains and demonstrates the essentials of the action, which is convenient for students to learn and understand.The multimedia courseware fully displays all the teaching content in the form of pictures, texts, and animations.
(3) Video analysis Teachers decompose actions according to video explanations, students discuss and explore the characteristics of tactical basic coordination, and multimedia courseware controls the playback of videos by playing, pausing, turning forward, turning back, etc., which is convenient for analysis and explanation.
(4) Test questions Teachers provide test questions and students conduct test questions to consolidate the mastery of knowledge points.Multimedia courseware is controlled by programs to automatically change questions, calculate scores, and give standard answers.

Courseware Production
(1) Selection of courseware making tools In the example of this research, FlashMX2004 is used to complete the multimedia courseware of basketball tactics basic teaching.The whole courseware is easy to be embedded in the web page and suitable for transmission on the Internet.Use the scanner to scan the text part into the computer, recognize it with Hanwang HWOCR5.0 recognition software, and edit it in Word.Use the video processor and audio processor of Kingsoft Hasee II to convert the VCD to the .avivideo file format, use Windowsmoviemaker to edit and integrate the edited film, and finally import the required materials into Flash as needed to make the courseware.
(2) The validity of the courseware In order to ensure the correctness and effectiveness of the basic actions in the courseware, the validity of the content of the courseware was tested and the empirical validity evaluation method was adopted.10 experienced teachers (including 4 professors and 6 associate professors) are invited to review the initial courseware, and evaluate the courseware at level four, namely, accuracy, basic accuracy, suggested revisions and inaccurate evaluations, based on the opinions and suggestions of experts, To modify and supplement the courseware.The feedback of such survey opinions is an iterative process, and the audit results are shown in Table 1.2) Image source: ① After the image is obtained by the digital camera, it is directly input to the computer.

Conclusion
②Use the scanner to scan the relevant pictures and input them into the computer.
③Download relevant photos from other webpages and save them to the computer.
3) Sound effect source: ① Use the computer program-attachment-recorder to record the sound, and save it in the computer in the form of WAV file.②Intercept the sound files in other software, obtain the files (WAV and MID) and save them in the computer.③Download relevant sounds from other web pages and save them to the computer.

4) Text source:
On the Founder Aos development platform, use Word to write directly.

Test Content
Before the experiment, the physical fitness and basketball foundation of the experimental group and the control group were tested.The test content and standards are: (1) Basic test: full-court turnback (s) (time counting).
(3) Basic tactics test: Three half-court passes, scoring, and screen tactics are used to test the success rate (10 attacks per group) (counting the number of goals).

Comparative Results of the Experimental Group and the Control Group in the Evaluation of Students' Theoretical Knowledge
After the teaching experiment, in order to test the mastery of the basic basketball tactics and theoretical knowledge of the two groups of students, a test of basic basketball tactics and theoretical knowledge was carried out.The test questions were mainly judgment and selection.The comparison results of test scores are shown in Table 2.The ratio of the number of people in each segment of the test group is shown in Figure 2, and the ratio of the number of people in each segment of the control group is shown in Figure 3. From the comparison results, 22 people with a score of 90 or more in the experimental group accounted for 27.5%, and 13 people with a score of 90 or more in the control group accounted for 16.5%.The students in the experimental group have a higher level of basketball theoretical knowledge than the students in the control group.The test result P<0.01, the degree of difference is more obvious.In addition, in terms of curriculum content design, 82.19% think that the curriculum content design is appropriate; 69.43% think that the resources provided are very rich, and 12.08% think that they are not rich enough.35.9% think that the self-test questions and practice questions after the chapter are troublesome or boring, so sometimes they do a little or basically not, so we have to work harder here.
69.81% think that the visual design of the webpage is good, which is in line with their spiritual pursuit.
89.21% think the course navigation design is better.23.29% thought that there was no professional learning atmosphere in the learning forum, and the problem could not be solved in time, 34.12% thought it was a bit helpful, and 10.21% thought there was no topic to communicate.It can be considered that the basketball multimedia courseware can obviously promote the students to master the theoretical knowledge of basketball tactics.

Satisfaction Degree of the Students in the Experimental Group and the Control Group
In order to understand the degree of students' satisfaction with basketball teaching, the form of afterschool questionnaire is used to solicit the opinions of the experimental group and the control group, as shown in Table 3. Statistics show that 95% and 87.5% of the students in the control group and the experimental group are very satisfied and satisfied with the basketball class.The satisfaction results of the experimental group and the control group are shown in Figure 4.In the discussion, some students thought that the courseware was very helpful for learning and helpful for cultivating cognitive ability.
Consolidate knowledge through exercises, and lay a solid foundation for future study and work, and I sincerely hope to use this kind of courseware to learn more in the future.Expert judges also agreed that the courseware was designed very well.It can be seen that multimedia computer-assisted teaching plays a positive role in cultivating students' interest in learning.

Comparative Results between the Experimental Group and the Control Group
In order to test the effect of the implementation of the courseware, through the three-week teaching competition, after the teaching experiments of different groups are completed, 3 experienced teachers (1 professor and 2 associate professors) will conduct teaching competitions on their own teaching groups.
The experiment results of the teaching competition are shown in Table 4.The comparison results between groups are shown in Figure 5.It can be seen from basic basketball tactics is significantly higher than that of the control group students, and the degree of difference reaches the expected level.Therefore, we should use a variety of methods to comprehensively evaluate the learning effect of online courseware learners, or evaluate and analyze based on a standard index system.However, in this courseware, the evaluation is mainly based on expert evaluation.There is no mature idea for the evaluation and dynamic monitoring of those ill-formed knowledge, which needs to be further strengthened.

Basketball Tactics Courseware in Teaching by Experimental Group Students
In order to fully understand the effect of courseware teaching, a questionnaire survey is used to understand the evaluation of the experimental group students on the application of computer-assisted teaching methods to basketball tactics basic teaching.The results of the evaluation investigation and analysis are shown in Table 5, and the summary results of the corresponding investigation and analysis are shown in Figure 6.The five items of the survey showed that the positive attitudes were 92.5%, 100%, 98.8%, 95%, and 91%; the general attitudes were 7.5%, 0, 1.2%, 5%, and 8.7%.This fully shows that students have a positive attitude towards using multimedia basketball courseware.Therefore, in conventional teaching, teachers' explanations and demonstrations are easily restricted by many factors  etc. Enable animation teaching to break through difficulties and strengthen key points.Another feature of animation is that it is convenient and efficient.It can break through the limitations of time and space, shorten the process of a certain object, or understand the relationship between its causes and results, so that it can highlight key points, disperse difficulties, and achieve obvious results.The limitations of teacher's action demonstration will inevitably cause errors in students' understanding.Using basketball animation to express these changes has the advantages of good time and space, strong overall effect, and deep impression.In the courseware, multimedia technology is used to intuitively express the basketball movement circuit, which is easy to understand and simplifies complex tactics.The results of tactical understanding and execution are shown in Table 6.From the comparison of the overall tactical understanding and execution effect of the experimental group and the control group, it is found that after 52 hours of teaching, the test group's performance is significantly higher than the control group, and the difference between the two groups has reached a significant level of difference, indicating that the experimental group The teaching has a significant effect on cultivating students' tactical awareness and improving tactical judgment and application ability.The results of tactical understanding and execution analysis are shown in Figure 7.The results of several test items show that there is no significant difference between the two groups after the test.This shows that the courseware method is no different from traditional teaching methods in technical mastery, but the difference between the two groups in tactical application and theoretical testing is very significant.The students in the experimental group have a significantly higher understanding of the entire tactics than the control group.They also have a solid and firm grasp of the theory teaching film after learning.It shows that in terms of theoretical teaching, it is superior to traditional coach oral explanation methods.In the interviews with students, most students hold a positive attitude towards the courseware method.knowledge of intrusive fouls and fouls was significantly higher than the students in the control group.It can be explained that the intrusion and fouls courseware has a more obvious promotion effect on students mastering the theory of intrusion and fouling.The teaching experiment proves that the way of using multimedia courseware to learn is effective and feasible during the learning process of the students' offense and foul referee.The rich text, sound, animation and video materials of the multimedia courseware are unified, and the effective editing and application can receive the expected experimental results.Multimedia courseware can visualize the knowledge in the book, the amount of material information is large, the complicated text description is eliminated, the intrusive and foul action can be reproduced, frozen and analyzed, and the teaching situation on the spot is created.In particular, the benign interaction between vision and hearing can better attract and concentrate students' attention and improve learning efficiency.Since the courseware is completed under the condition of "0 class hour" students self-study, it has played a good role in promoting the development of students' self-study ability.

5.Conclusion
The introductory part of the teacher points out the key points and difficulties of this course, students have a preliminary understanding of this course, and the multimedia courseware displays the entire content catalog of this course.Each chapter is based on the teacher's explanation and demonstration of the action essentials, which is convenient for students to learn and understand.The multimedia courseware fully displays all the teaching content in the form of pictures, texts, and animations.In the video analysis part, teachers break down actions based on video explanations, students discuss and explore the characteristics of tactical basics, and multimedia courseware control video playback through play, pause, forward and backward, which is convenient for analysis and explanation.Teachers provide test questions, and students conduct test questions to consolidate the mastery of knowledge points.
Multimedia courseware is controlled by programs to automatically change questions, calculate scores, and give standard answers.
In the process of teaching goal customization, according to the demand analysis, the predetermined teaching goal is refined, that is, the professional teacher with rich teaching experience analyzes the teaching material, analyzes its knowledge structure, and draws the level, sequence and mutuality of the knowledge structure.The logical relationship between.According to the attributes of each knowledge point (facts, concepts, principles, technical characteristics, problem solving, etc.), list the levels.It can be seen from the experimental results that multimedia computer-assisted teaching has a positive effect on cultivating students' interest in learning and forming the habit of lifelong exercise.
