摘 要
隨著 Internet的快速發(fā)展，網(wǎng)絡(luò)技術(shù)及多媒體技術(shù)對教育領(lǐng)域的改革產(chǎn)生了重大的影響，網(wǎng)上教育已經(jīng)成為培養(yǎng)人才、促進(jìn)科研和教育事業(yè)發(fā)展的重要途徑，網(wǎng)上學(xué)習(xí)作為新的教學(xué)模式正在建設(shè)和發(fā)展著。
然而傳統(tǒng)的B/S（瀏覽器/服務(wù)器）模式的應(yīng)用程序由于受制于HTML的限制，無法像C/S（客戶端/服務(wù)器）那樣使用豐富的效果來顯示數(shù)據(jù)，用戶體驗(yàn)比較糟糕，無法滿足教師、學(xué)生的要求，更不能激發(fā)學(xué)生學(xué)習(xí)的興趣，沒有充分的發(fā)揮促教勵(lì)學(xué)的作用。
如何向用戶呈現(xiàn)良好的用戶體驗(yàn)、完整的學(xué)習(xí)材料，及時(shí)、準(zhǔn)確地解決學(xué)生在學(xué)習(xí)中碰到的各種難題，便捷的管理學(xué)生作業(yè)、提高教學(xué)質(zhì)量和效率，完成教學(xué)資源平臺以及做好學(xué)習(xí)的評價(jià)、督促和管理等是構(gòu)造一個(gè)良好的教學(xué)資源平臺的關(guān)鍵技術(shù)。本文圍繞上述問題開展工作，針對AJAX技術(shù)進(jìn)行部分分析研究，通過對實(shí)現(xiàn)AJAX的四項(xiàng)關(guān)鍵技術(shù)及其在AJAX實(shí)現(xiàn)中所起的作用的分析，重點(diǎn)研究了基于AJAX的教學(xué)資源平臺前臺系統(tǒng)設(shè)計(jì)，借助于AJAX技術(shù)，使得該教學(xué)資源平臺具有個(gè)性化、友好性、穩(wěn)定性、易用性、安全性等的優(yōu)秀性能，成為教師授課、學(xué)生學(xué)習(xí)不可缺少的教學(xué)資源共享平臺。

The design of Teaching Resources Platform’s foreground based on AJAX
Abstract
With the rapid development of Internet, the network technology and the multimedia technology have a tremendous bearing on educational reform. E-education has become one of the most important ways of education and researching. E-learning as a new educational model is underway and developing.
However, B/S application program confined to HTML is not capable of displaying data with abundant effects as C/S does. As a result, it fails to meet the demands of teachers and students, nor can it arouse students’ interest in learning, with its poor encouraging role.
The essential factors in developing a well-functioning teaching resources platform lie in such aspects as offering satisfactory users’ experience, presenting integrated and abundant learning materials, promptly and effectively addressing the difficulties rising in students’ learning, efficiently checking and correcting the assignments of students, enhancing the qualities and efficiencies of teaching as well as assessing, supervising and managing students’ academic activities.Focused on the factors mentioned above and through analyzing the four key techniques to implement AJAX and its contribution to AJAX realization, this dissertation aims to discuss that applying of AJAX techniques and the design of the AJAX-based teaching resources platform’s foreground will enable the teaching resources platform achieving outstanding functions characterized by distinct individuality, stability, and safety. The platform, easy and convenient to operate, thus turns into an essential shared teaching resources platform for both the teachers and students.
Key words: AJAX ;B/S ;Teaching Resources Platform;Stability
