    • Design and Application of Multimedia Network Course based on Web Nong Zheng College of Education Science Guangxi University For Nationalities Nanning ,China nongneal@163.comAbstract—With the Guidance of the theory of teaching systemdesign and the theory of modern studying, this article A. Teaching system design theoryintroduces the teaching design strategy, the system design and Teaching system design is the study of methods of thethe implementation technique, and analyzes the importance of design and development of teaching system. Take the systemthe security of the system management, information approach as the core, the system explores teaching andmanagement and system maintenance and update in the learning system between each essential factor and the wholenetwork course. essence relates. The theory of learning and the teaching theory will be systematically applied to solve practical Keywords-WEB; Teaching design; Design of network course problems, and a teaching system is formed which can realize the teaching function, complete the teaching goal and I. INTRODUCTION promote the optimized teaching. There are three main kinds With the development of information technology, Multi- of instructional design theory, that is, (1) the teaching-media network teaching plays a more and more important centered instructional design for teachers to teach. (2) therole in the higher education courses, which can open up learning-centered instructional design for students to study.wider space for autonomous learning ability of college (3)the dominant-the union” instructional design for astudents and promote students study and exchange in the combination of both.virtual network environment. Multi-media network teaching System theory states that the system is a collection ofsystem has characteristics of mutuality and dynamic, which interrelated components that function together to achievemakes teaching become more flexible and more humanized, some outcome. A network course is a particular subjectand it can bring up and waken students learning interest and teaching of the network teaching. Under multimedia andcan make students have the ability to collect, collate and internet settings, the teaching process can be divided intoprocess the learning information and can bring up ability of three essential factors-the teacher, the network course and thestudents to improve teaching quality. The instruction system student.development of technology and application for Multimedia The teaching process is shown in figure 1.

Humanism Learning Theory study way, is the embodiment of learners on the subject Humanism learning theory states that study is not simply position, which can make the learner give full play to thethe relationships between stimuli and response, but a sense of initiative of learning.psychological process. Learners are the subject of learning Thus, the network system design should be noted thatand they can teach themselves, everyone has the potential to several areas of the functional characteristics 1learn, learning is essential for self-fulfillment. Study is one of Accentuate the characteristic of The network study, embodythe individual needs. Learners will take encouragement from the leading position of the learner autonomy. 2 Achievelearning when they learn actively in the course of learning. individualized learning and personalized services to meetIt is the most enduring and the most lasting learning when different levels of learner individual requirements. 3 Paylearners play a part on their own volition in learning. attention to navigation design, interaction design andPersonal influence is essential in effective learn, study with a animation design, satisfy the needs of autonomous learningpartner and study in groups can urge learners to study hard.The research of humanism learning theory emphasizes the under network environment. 4 Pay attention to teachingcentral role of learners, advocates learners to study evaluation and feedback, keep abreast of students abouteffectively and stresses the importance of self-evaluation. learning, to update content design, environmental design, evaluation method, and the management model. [4]C. Constructivism Learning Theory III. THE STRATEGY OF TEACHING DESIGN [5] Constructivism learning theory defines knowledge asbeing, “with the help and cooperation of others by making A. The Design of Teaching Objectivesfull use of the essential study materials and by means ofconstruct meaning, the learner constructs initiative the The teaching goal is the teaching pilot, is grasping theproperties, the inherent laws and internal relations of things teaching travel direction. In order to let the learners have ain certain situation”. The learning process is that the learner preliminary understanding of the scope and overall directionconstructs a new knowledge guided by the past successful of the curriculum, a detailed and clear instructional objectiveexperience, through the interaction with the outside world. should be designed, a brief description should be given of the Therefore, constructivism learning theory attaches great front theory and technical, the daily life application and theimportance to the role of the learning environment in the future trend of development. In the network course, thecourse of study, states that” the situation”,” the cooperation”, teaching announcement and the teaching guide is designed,“the conversation” and “the significance construction” are the direction and the basic survey of teaching is indicated,the four elements of learning environment. Constructivism the teaching purposes, tasks and requirements, elements forlearning theory emphasizes that study is the student-centered each chapter title and time allocation is described in detaildriving exploration, initiative discovery and the initiative and references are given in the course, etc.construction. That is, the capacity to acquire knowledge B. The Design of teaching contentsdepends more on the learner according to oneself experience The course content is to achieve the teaching goal, toto construct relevant knowledge than on the capacity to make the course more systematic, more comprehensive andremember and recite what the teacher teach. more visual, to arouse the initiatives of learners on the The teacher acts as a guide and a helper in the teaching bountiful expressions. Therefore, according to theprocess, that is, helps the student to form the academic requirement of teaching content design, the knowledgemotivation, stimulates students study interest, through the points and the relevant concepts of the course will beestablishment suitable situation, helps the student to organized and designed, to reflect the logical relationshipconstruct the knowledge what the student has learned. In between knowledge points, manifest the teachingorder to cause the significance construction to be more characteristic and the teaching rule, and show the structureeffective, the teacher should organize cooperative learning, and the function of knowledge.discussions and exchange. The content of the network course is open to meet theD. Autonomous Learning theory [3] study needs of the learners to the maximum extent possible Autonomous learning theory states that autonomous at different times and places; the network course is abundantlearning is a study mode, which mainly includes the in study resources, there have on-line multimedia resources,following factors: learners lead the study intrinsic the experiment demonstrate, exercises and reference book formechanism, the ability of learners to control their own teaching, etc. Moreover, the course needs to extend thelearning objectives, the study content, learning methods and relevant knowledge that includes borderline subjects ofthe use of learning materials. If the learners are all active relevant knowledge, the relevant knowledge of correlativeparticipants from the meta-cognition, motivation and and the overall quality of the relevant social practicebehavior, the study is the autonomous learning. certification exam content knowledge, to meet the study All in all, Autonomous Learning usually means the needs of the learners of relevant knowledge.ability of a person who can make a self-conscious set C. The design of interactionslearning goals, make a study plan, choose the learning The equations Interaction is the main characteristic of themethod, monitor the learning process and evaluate the result network course, it is crucial to the teaching quality and
