Discussion on developing Web courseware with Java technology

With the rapid development of computer technology, the process of education informatization and networking has been deepened, especially the internet/intranet of TCP/IP protocol, the use of computer technology and network Technologies has become an important development direction of modern education, web-based teaching software can make maximum use of educational resources in modern education, so it has been developed rapidly.

Teaching courseware refers to the computer software with the function of teaching, to some extent can replace or assist teachers to carry out teaching. web-based teaching software based on Internet/intranet network, the teaching content is represented by Web page, this kind of teaching courseware has the characteristics of openness, flexibility, interactivity and dispersibility of distance teaching, it organizes knowledge in some fields according to teaching goal, gathers into modules, Form a hierarchical, networked structure, made of page-style or scripted courseware. After the courseware is finished, it is managed with WWW server. The client uses IE and other browsers to browse, and through the Web page Interactive learning, to achieve a relatively independent teaching mode in time and space, compared with the traditional classroom education, the new way of education is the most important characteristic of breaking the time and space constraints, No longer rely entirely on face-to-face teaching between teachers and students. Under the new teaching method, the students give full play to their autonomy, determine the learning content and arrange the progress according to their actual situation, so as to meet the need of popularization and independence of education, which is suitable for all students with learning requirements. This way has become the main direction of teaching courseware development.

The composition of network courseware

In order to give full play to the advantages of network teaching, we must follow the teaching law of modern education and carry out scientific teaching design. Instructional design is the application of systematic methods to analyze teaching problems, to determine teaching objectives, to establish the steps to solve problems, to select corresponding teaching strategies and teaching means, and finally to analyze and evaluate the results of the operation process. Therefore, as the network courseware system should have the scientific composition, the author thinks the network courseware should include the remote login, the network course, the Exchange area, the resource area, the homework examination area and so on function module. The whole system is as shown.

1, remote login. Students can enter into study, discussion, questioning, homework, examination and so on through the authentication. After authentication, teachers can conduct online tutoring and answer questions, publish information and conduct assignments and test evaluations. Through the number of logins and browsing time, to a certain extent, reflect the learning situation of students.

2, network tutorials. Is the main part of the courseware. The learning content can be designed by chapter or subject. First, cover all the knowledge points of the chapters or topics. Secondly, the relation of each knowledge point should embody the characteristics of subject teaching and reflect the teaching law of the subject. Third, the knowledge system should have its own elements, structure and function. Therefore, in the course of courseware design, we should show the knowledge structure function at the same time, so as to facilitate the students ' study.

3, communication system. To email, forums, bulletin boards, to provide learners with a learning and exchange of places, on some issues and teachers, students to discuss, exchange of learning experience, can also put forward their own views, consult others views. Through a variety of forms of communication, to help learners deepen their understanding of some problems, broaden their own thinking.

4, resource system. refers to the topic or chapter content related to background information, different points of view data, relevant comments and other content, also includes reference books and learning content related to the domestic and foreign www site. The aim is to broaden the horizons of students and to understand more deeply the content of learning.

5, testing system. Mainly include the chapters or topics of the exercises and test questions, used to check the students self-examination of the basic knowledge, basic skills mastered the situation, including objective questions, subjective questions, for objective questions can give corresponding answers, and subjective questions can give reference answers or ideas.

Design method and technology of Web teaching courseware

The general idea is that the courseware design method is divided into two parts, one is the use of Flash, Dreamweaver and other tools to develop the static part of the Web page, the second is the use of Java, JSP and other development dynamic, interactive part.

1. System software Configuration

JSP development of teaching courseware based on WWW, as a system mainly composed of three parts:

1) JSP server. The JSP server we use in development is resin, a free JSP server that can be used as a plug-in for IIS, so that site servers can be easily managed using IIS. Of course, for Linux users, Tomcat is also a good choice.

2) database. In the courseware development, the database technology is mainly used to support remote login, network tutorials, communication area, homework test and other Dynamic Web page data access. We use Access databases in development and the entire site runs under Windows2000server.

3) Browser. The most widely used is Microsoft's IE and Netscape company navigator.
