摘要
为进一步提高我国人口素质，近年来，高职教育得到了高速发展。高职教育的主要目标是培养技能型的人才。技能型人才的培养，必须给培养对象创造便利的学习环境。在培养对象的积极参与下，由培养对象进行多次训练才能掌握相应的技能。由于教育资源的缺乏和常规教学设备使用的非便利性，在正常教学过程中，要随时给学生提供便利的学习和技能培训环境存在相当的难度，这给教学目标的实现带来很大的困难。网络教学的出现为解决这一困难提供了便利。
全球信息技术的迅猛发展，尤其是网络、多媒体技术和网络通信技术、压缩等核心技术的发展为远程网络教学提供了良好的施展平台。目前我国大多数高校都已开办或正在开办自己的远程网络教学，各种网络教学课程日益增多，良莠不齐。如何设计网络教学课程，达到真正符合教学设计思想、利用网络优势和充分发挥学生主体作用是本课题研究的重点。基于此，本文以基于建构主义的“数字电子技术”网络课件的研究作为自己的硕士论文选题。建构主义强调在教师指导下的、以学生为中心的学习。学生是信息加工的主体，是认知结构的主动建构者；教师是意义建构的帮助者、引导者与促进者，而不是知识的传输者与灌输者。这一理论非常切合高职教育的教育模式。本文首先讨论了以学生为主体的建构主义教学理论以及教学设计。研究了基于建构主义理论的远程网络教学的特点、学习原则及其教学模式。在此基础上研究适应于强调技能教育的高职教育的网络教学的教学理论及教学设计。在制作过程中，充分利用目前流行的网站制作技术，力求在理论和实践上摸索出一套适合制作理工科类专业基础课网络课程的实用方法。
(1)基于建构主义教学理论的数字电子技术网络教程总体设计。对数字电子技术课程进行整体规划，着力构筑有利于激发学生积极性，能够培养学生技能的学习环境。
(2)数字电子技术理论教学设计与实现。运用当前先进的教学理论和方法，紧密结合多媒体教学辅助软件发展的趋势，采用多媒体技术和网络编程技术，研制基于Web的网络教学网站，给学生营造有利于他们自主学习的平台，以克服传统教学模式和教学方法的不足。
(3)利用EWB软件平台，开发“数字电子技术”仿真实验系统。利用EWB软件平台，开发“数字电子技术”仿真实验系统，以可视化的分析方法，为学生提供直观的分析结果，克服“数字电子技术”课程中实验和试制电路局限于实验室的问题，提高实验的便利性，以提高学习的效率。
(4)开发基于Internet网络的考试系统。考试是一种有效地检查学生学习效果的手段。利用考试系统，学生可以很方便地发现自己在学习上的不足，有针对性地进行学习。
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.
