摘要
网络教学是一种崭新的现代教学模式，它具有时空广阔、趣味性、双向性、实时性强等特点。随着多媒体与网络技术的不断发展和教育投入的增加，网络教学将彻底改变传统的教学模式，成为未来教学发展的趋势。
作为工科院校机械类及机电类专业的一门重要必修课程——“液压与气压传动”，目前在我国的教学中大都还是采用传统的课堂教学模式，而该课程的网络教学还几乎没有。本课题的研究与开发就是为了使该课程的教学适应教学改革和未来教学发展的需要，并且更加有利于机械类及机电类专业或相关专业人才的培养。
本课题充分运用现代计算机多媒体和网络技术，开发了“液压与气压传动”多媒体课件，并把其嵌入“液压与气压传动”课程的教学网站，使其达到网络教学的目的。在整个研究和开发过程中：
首先，对已有部分“液压与气压传动” MCAI课件的教学内容和教学特点进行详细的分析和研究，结合多媒体和网络的特点，利用多媒体开发工具Authorware5.1继续开发了后续的部分章节，使其既具有多媒体教学软件的功能，又适合嵌入网页。
其次，利用Authorware5.1网络功能——“流”技术对课件的各章节分别进行网络打包。
最后，按照双主教学模式(即发挥教师的主导作用和学生的认知主体作用)，并且在遵循网络课程教学设计原则的基础上，进行“液压与气压传动”课程的网站设计与开发：①利用网页开发工具FrontPage2000进行网站总体风格、界面、导航风格以及学习课程所需辅助功能的设计与开发；②利用JSP及其，TavaBeans组件技术进行实际的程序开发，以达到对后台数据库的操作、实现网站注册及登录、实现为学习提供的搜索和学习跟踪等等各种网站功能及教学目的；③把网络打包好的课件嵌入相应的网页中，并对这些网页的链接进行调节，使其达到预期的要求，并在校园网上进行调试运行通过。
作者希望该课题的研究与开发能对我国现代远程教育资源建设作出点滴微薄贡献，能使“液压与气压传动”课程的教学跟上时代的需要，从而促进液压与气动技术的发展和进步，也希望能对其它机械专业类课程网络教学的开发起到一定借鉴作用。
Network Teaching is a kind of brand-new modern teaching mode, it has characteristics, such as space-time wide, the interest, two-way quality, real-time character. With the constant development of computer multimedia technology and network technology and increase of the input in education, Network Teaching will change the traditional teaching mode completely, and become the trend of teaching development in future.
"Hydraulics & Pneumatics" as a important required courses of the specialty in universities and colleges' machinery and electro-mechanics, its teaching in our country mostly adopts the traditional classroom instruction mode at present, though some schools adopt the teaching way of the multimedia CAI now, but there is not the Network Teaching of this course. The research and development of this subject, in order to make the teaching of this course meet the reform in education and need of teaching development in future, and is more favorable to the cultivation of the machinery and electro-mechanics specialty or relevant qualified personnel in a specific field.
This subject fully uses the multimedia of the modern computer and network technology, have developed a multimedia courseware of "Hydraulics & Pneumatics ", and imbed it in teachings website of the course of" Hydraulics & Pneumatics ", Make it achieve purpose of Network Teaching. In the course of whole of research and development:
First of all, have carried on detailed analysis and study to the content and teaching characteristic of the multimedia CAI of "Hydraulics & Pneumatics " that already have a unit that ran, Utilize AuthorwareS.l, which is a multimedia develop software, continue to develop some following chapters. The development combine the characteristics of the multimedia and network. It no only has the function of teaching software of multimedia, but also suitable to imbeds the web page.
Secondly, utilize the "flow" technology of the AuthorwareS.l network function, divide every chapter to some segments which suitable to running on the network.
Finally, according to the mode of two-roles in teaching, which should give play to teachers' leading role and also fully reflect students' cognitive subject. And on the basis of following the course teaching design principle of the network, carry on the website design and develop of the course of "Hydraulics & Pneumatics ". Firstly utilize FrontPage2000 of the developing instrument of web page to designed and develops website's overall style, the interface, style of navigating and studying the supplementary function that courses need; Then utilize JSP and JavaBeans discreteness technology to carry on real procedure making, In order to reach the function of various kinds of websites and teaching purpose, such as the operation to backstage supporter's data base, realize website's registration and log on, realize the search and study offered for studying and is tracking the studying; Then imbed the network packs in the corresponding web page, and regulate the linking of these web pages, make it reach anticipated request, and debug running in campus network.
The author hopes that the research and development of this subject can make the teaching of the course of "Hydraulics & Pneumatics" keep up with the need of the times, thus accelerate the development and progress of hydraulic pressure and pneumatic technology, At the same time get certain reference function to kinds of course Network Teaching of other mechanical specialty too.
