Vocational courses for network optimization

Abstract: With the multimedia Technology, computer network Technology, the growing popularity of online courses as an effective form of lifelong learning in the world has seen rapid development, especially the Internet and campus network integration for the college education of the rich resources, the network program to truly become a reality. how to effectively use online resources to construct a modern web-based teaching more and more attention in education and gradually become a research hotspot, while the majority of our online courses still remain In the early stages of online course study, stay in the "construction" issues, and with the rapid popularity of online courses, how to optimize and innovate, play online course of practical utility, is an urgent need to study the problem for the In this paper, an overview of online courses and online courses to learn the status of theory, based on the course Higher Vocational network optimization and innovation.

Paper Keywords: multimedia information Technology, computer network Technology, online courses, optimization

First, the basic status of online courses at home and abroad
Foreign network course construction started earlier, in which Massachusetts Institute of Technology, University of California, Berkeley, University of Utah, University of Washington has a large number of online course resources, including Massachusetts Institute of Technology as of 2009 the door has been excellent network of more than 1800 online courses In the sharing of network resources, the United States to implement the various universities are basically open, unified platform for sharing of network resources, school, co-operation between the schools sharing is the norm.

Looking at the domestic network of courses, mainly still in the WEB page with the static display, combined with the limited multimedia tools, part set is more formulaic, generally include: curriculum, teaching videos, courseware, practice exercises, etc., are commonly used in the presentation: text, pictures, tables, FLASH animation, streaming media and PPT, curriculum organization, or to imitate the basic teaching of linear, there is no target for education, educational objectives, teaching content for specialized design and concept, although the courseware, exercises and other teaching resources than the whole, but generally the older, slower, or basically not update update shows that most of the curriculum in China's second generation network, some still in the first level, only some very small number of colleges and university network using Radio and TV University Video conferencing system. With the rapid popularization of online courses, how to optimize and innovate, play online course of practical utility, is an urgent need to study the issue.

Second, the network theory courses
Constructivist learning is that learners in the process of interaction with the environment within the active construction of the mental representation of the process. The meaning of the five lesson online course: learners actively construct knowledge, so the network curriculum design to student as the center, students develop initiative, emphasizing the learning situation, which is why online courses designed to focus on the creation of situations, knowledge of the construction of both the restructuring of existing textbook knowledge, but also the significance of new information on the network construction, emphasis on learning society, that online courses designed to provide a platform for exchange of learners, emphasizing the construction of network resources, the importance of meaning.

Blended learning is a combination of a variety of learning styles, such as computer-assisted instruction and traditional teaching of the combination of self-learning and collaborative learning with, etc. in the network teaching, blended learning is the essence of the traditional advantages of learning and digital or networks combine the advantages of learning it is the world's remote education, after a decade of exploration, research, and come up a new understanding of international distance education on the educational theories and concepts of major improvement and major change.

Third, the constraints of the domestic network key issues of sustainable development programs
I started college I teach a course for the implementation of the network effect of the survey, 500 students participated in the survey, 65% of the students that the existing network of teaching effectiveness is not significant, the main problems are:
(A building mere formality, the students showed little reaction, ineffective teaching
(Two content updates are not timely, well managed, low popularity
(Three online courses are somewhat theoretical knowledge, the lack of interaction and teaching methods of a single
(D virtual experiments focused not strong, lack of awareness of its limitations
(Five courses to explain the deviation from its original purpose
(F learner's non-intellectual factors did not pay sufficient attention to
(Seven pairs of students learning process without effective monitoring, evaluation, feedback mechanisms
These status and problems of the sustainable development of our online courses, university networks affect the pace of course construction, because more is necessary to reform the current online courses, online courses can explore a truly carried out, to play its the actual efficacy of the construction of the road. In this paper, an overview of online course in learning theory, and network status on the basis of courses, courses in Higher Vocational network optimization and innovation.

4, the network optimization program
(An online course module optimization
On the course type, the network is the basic course curriculum, development of curriculum and creative courses. Accordingly, contents of web design courses from three aspects: knowledge module, the development of knowledge modules, creative knowledge modules: basic knowledge module is delivered to students basic knowledge, basic concepts, focusing on the phenomenon, the interpretation and definition of the concept description, the development of knowledge module mainly for basic knowledge transfer and application, visit the students have learned to grasp the situation, the development students intellectual, creative knowledge module is a higher demand for students is the cultivation of innovative capabilities of students.

(Two courses technology environment to optimize network
Successful online courses should be both technical and teaching guide provide effective learning support services. Technical sense-making activities, the environment is important to support effective implementation, it can self-learning for students and provide a powerful cognitive frame, the creation of an effective learning environment and provide a powerful resource integration environment based on cognitive flexibility theory, we want to establish an effective knowledge construction environment, and learning resources and tasks for effective organization and management. In particular, well-structured knowledge in the field of non-openness of problem-based learning activities, provide technical environment supporting role of cognitive and straight and spiral curriculum forms of organization is necessary.

Prevalent in the current network in order to submit a teaching job waiting for scoring the next phase of the three stages of learning. This self-assessment of student learning is the cognitive structure and the optimization and reorganization of very unfavorable. Online course evaluation should be a process of evaluation, this evaluation should be able to teachers and students and the next instruction and management to provide the necessary feedback while the demand for different objects of evaluation to determine the evaluation itself should be multi-dimensional, multi-perspective , various forms. Currently, more effective evaluation, including portfolio assessment, peer assessment team, one minute questionnaire, etc. In these outstanding students in the appropriate evaluation of knowledge acquisition and cognitive element of knowledge of the evaluation factors are also very necessary.

(D interactive system optimization
Effective interaction on the premise should be to ensure the fluency of communication, according to the theory of distributed cognition perspective, the network information should not dominate the curriculum in the hands of some authority, but should be evenly distributed throughout the learning community. Successful learning should be based on collaborative knowledge construction information among members of a community of equal sharing, the collective contribution and access to knowledge and equal opportunities for self-improvement, therefore, technology and online courses for members of the task lies in the effective interaction and active information sharing and AC pass without proper authority or over-reliance on the exclusion of others to establish a small group of extreme performance, each member should contribute to the responsibilities and rights, and this reflects the self-study and individualized learning, collaborative learning three by a combination of interactions is based on the basis of collective cohesion.

(E network optimization course content
Curriculum should first of the two types of online courses that focus on organizational learning activities and learning resources, learning activities around the optimization and integration of learning resources to create conditions for effective implementation, therefore, the curriculum should include course materials, extra-curricular resources, and students in the learning activities which generate resources in three areas of knowledge The course syllabus and teaching materials around the target refers to well-organized curriculum resources, extra-curricular resources, including scalability, cross-disciplinary reference, authoritative information and related learning sites, students in learning activities which are mainly refers to the network resources through interactive programs, exchanges and cooperation in the form of organized learning activities, students create and organize their own learning resources in many online courses focus on the current course materials and extra-curricular resources, neglecting the students collaborative interaction in the formation of learning resources. In fact, these resources truly reflect the students 'sense-making process is the students' knowledge of the brain sources, we know the students through these resources and knowledge of the current level of knowledge structure, even students can learn to track and detect cognitive and metacognitive aspects of shortcomings and deficiencies, it will establish for teachers under a zone of proximal development, to develop a reasonable division of tasks and activities may be out of teaching objectives in real-time detection and correction to provide an important reference.

(Six network interface optimization program
Interface is the learners and online courses online courses to pass information between the system and medium of exchange, the learner through the computer interface to control the input, query and manipulate the curriculum through the provision of information to the user interface for reading, analysis, determine The network interface not only affects the course of the appearance of the course itself, affect the students' interest in learning to create and maintain, and the operability of the curriculum and the ease of use is also a very important role a good interface can be easily understood and online courses accepted, so that learners understand and easy to use, while a poorly designed interface, the curriculum so that students have exclusive use of inconvenient, leading to Trek and so on.

V. Conclusion
In short, online course is a new type of educational resources in the country's development rather late, some of the current network of educational theory is in the exploratory stage, there is a lot to be desired: the new curriculum reform as an integral part of online course design must consider the characteristics of the network itself and the learner's objectives and requirements, comply with the online course "student-centered," the guiding ideology for online course development and construction, can not blindly follow the traditional classroom teaching standards for teaching design above is the author of that opinion. The purpose of the research is to draw people to the network to conduct a comprehensive research program to play the characteristics of online teaching, to make it more perfect.
