【摘要】：隨著現(xiàn)在技術的發(fā)展和人們對工作生活需求的提高,互聯(lián)網(wǎng)行業(yè)以其自身開放、共享、平等的特點,在各個行業(yè)都得到了充分發(fā)展和使用。在互聯(lián)網(wǎng)普及之前,人們交流的方式是兩周到達的書信,人們獲取信息的途徑是每日一版的報紙,人們娛樂的方式相對單一。但自從互聯(lián)網(wǎng)進入傳統(tǒng)行業(yè)中,工作生活的效率被提高幾倍,成本節(jié)省了許多,人們之間的信息互通不需再等待,做出一個決策也許只要5分鐘的時間。能買到的東西不再只是商場里陳列的有限種類,人們可以在互聯(lián)網(wǎng)上可以買到個性化定制的商品。互聯(lián)網(wǎng)正在一步步顛覆我們之前的生活工作學習方式。 互聯(lián)網(wǎng)進入傳統(tǒng)行業(yè)也是大勢所趨,目前在即時信息、電子商務等領域已相當成熟。但是在傳統(tǒng)問題頗多的傳統(tǒng)教育行業(yè),互聯(lián)網(wǎng)技術還沒得到有效地使用。在中國傳統(tǒng)教育行業(yè)中存在著許多問題,比如發(fā)達地區(qū)和偏遠地區(qū)所擁有的教育資源分布不均,線下教育受時間地點影響較大等,這些目前還沒有得到解決。 本文提出了一種使用HTML5新技術實現(xiàn)的在線教育系統(tǒng),HTML5是新一代的標記語言標準,跟之前的語言相比,一方面增強了瀏覽器Web網(wǎng)頁的表現(xiàn)性能,在瀏覽器上實現(xiàn)客戶端功能成為可能。另一方面增加了本地存儲和數(shù)據(jù)庫的應用,減少瀏覽器對插件的需求,如Adobe Fash。HTML5有許多豐富的標準庫,本文應用WebSocket、WebRTC和Node.js技術實現(xiàn)了適合時代需求的新型在線教育系統(tǒng)。
[Abstract]:With the development of technology and the improvement of people's demand for work and life, the Internet industry has been fully developed and used in every industry with its own characteristics of openness, sharing and equality. Before the popularity of the Internet, people communicated through letters that arrived in two weeks, people got information through a daily newspaper, and people had a relatively simple way of entertaining. But since the Internet entered the traditional industry, the efficiency of work and life has been increased several times, the cost has been saved a lot, the information exchange between people need not wait any longer, a decision may take only five minutes. What can be bought is no longer just a limited variety of items on display in the mall, but also personalized goods available on the Internet. The Internet is subverting the way we used to work and study step by step. The Internet enters the traditional industry also is the general trend, at present in the instant information, the electronic commerce and so on domain already quite mature. But in the traditional education industry, where there are many traditional problems, Internet technology has not been used effectively. There are many problems in the traditional education industry in China, such as the uneven distribution of educational resources in developed and remote areas, and the large influence of time and location on offline education, which have not been solved at present. This paper presents an online education system (HTML5) based on the new technology of HTML5, which is a new generation of markup language standard. On the one hand, it enhances the performance of browser Web web pages. It is possible to implement client functions on the browser. On the other hand, it increases the application of local storage and database, and reduces the browser's demand for plug-in. For example, Adobe Fash.HTML5 has a lot of standard libraries. This paper uses WebSocket,WebRTC and Node.js technology to realize a new online education system suitable for the needs of the times.
