Research On Digital Television Terminal Access System Based On EDOCSIS Study Of Manufacture Of Digital Electronic Technology Network Course Which Base On The Construction Principle

For further improving our country's population quality, HighVocational Education have obtained a high-speed development inrecent years. The main objective of Vocational education is trainingskilled personnel. The skilled personnel training must createconvenient study environment to the trained objects. With the objects'active participation, the objects can acquire the corresponding skillsthrough numerous times' training. Due to the lack of educationalresources and non-convenience of using conventional teachingequipment, in the normal course of teaching, it is quite difficult toprovide the students a convenience learning and skills trainingenvironment at any moment. This becomes enormous barrier ofachieving the goal of teaching. Teaching the emergence of thenetwork to address the difficulties of convenience. The networkteaching provides the enormous convenience for clearing this barrier.With global information technology developing rapidly, especiallythe core technologies of network, multimedia and networkcommunication and compression developing, a good display platformis provided for the long-distance network teaching. At present, themajority of our nation's universities have set up or are setting up theirown long-distance network teaching. All kinds of network teachingcurriculums are increasing, but the good and the bad are intermingled.How to design the network teaching curriculum that can accord withthe thoughts of teaching, and fully display the students' main roles anduse the network's advantage is the main research focus of thispaper. According to this, "Digital Electronic Technology" networksoftware research being based on constructivism is chosen as mymaster's thesis topic. Constructivism emphasizes student-centered learning whichunder the guidance of teachers. Students are the subject ofinformation processing and the initiative construction of cognitivestructure; Teachers are the helper, guide and promoter of meaningconstruction, not the knowledge transmitter and instiller. This theoryextremely suits the education pattern of Higher Vocational Education.Firstly, This article discuss has the construction principleteaching theory as well as the teaching design which for the studentas the main body. Studied the long-distance network teachingcharacteristic based on the construction principle theory, the studyprinciple and the educational model. Then studies the networkteaching principle and concerns the teaching design which sites toHigh Vocational Education emphasizes skill.The research's emphasis of the construction principlemainly has been put into construe learning environment. Thistopic conducts the research from following aspects.1. Select popular website design software DreamWeaver,synthesizesFlash software and the ASP programming languagedevelop Digital Electronic Technology curriculum network. Thisnetwork provide the corresponding information according to thestudents of High Vocational Education, provides the most basicenvironment for student's convenience study. This network providesthe basic knowledge which is needed by teaching, designs reasonableguidance system, then the student can choose the content whichaccording to individual's need.2. This papers emphatically studies the realization ofhypothesized experimental system. Base on the above stated, it isimportant attribute that lack the convenience practicality operateplatform which restrict the skill raise. Therefore, use the hypothesizedexperiment system, so long as has a computer, quite to moves the laboratory by the student. The student may carry on the experimentunbending. Student may use the hypothesized instrumentationequipment and the primary device, through carries on hypothesized inthe computer tests observes the electric circuit the work phenomenon,grasps the correlation of knowledge. User's experiment may becarries on the confirmation to in the textbook electric circuit, also maybe the change known electric circuit operational parameterunderstands the electric circuit the work essence, also may be oneselfdesigns electric circuit which can examine own actual skill.This hypothesized experimental system plans to use EWB whichmost suits for electronic circuit simulation. Design electric circuitthrough two kind patterns. First, manufacture related experimentproject uses the EWB technology, then manufacture experimentproject as play-over multimedia class, the student can view the imageof work process. Second, educates the student manufacture theexperimental electric Circuit with EWB, help student prepares forexperiment, convenience and effectiveness. The student also maytest the electric circuit use the EWB, thus enhancement experimenteffect. The student can use EWB to run design circuit.3. Operate. test system Test is an essential link of teachingprocess. The student can discover defect in study through the test.Then carries on strengthened study, grasps each part of knowledge.This papers plan to study operate test system on the net which useASP.net.The test system can provide convenient exam to the student,implement stochastic study principle. Test not only as one kind ofmeasure examine the effect, but also one important study way. Thetest result analysis may guide the student to study, goes thoroughlyexplores the relations of knowledge.The goal of the research is constructed a network study environment which has rich content, good alternation, real-timefeedback and humanistic.
