【摘要】:隨著現(xiàn)代計(jì)算機(jī)網(wǎng)絡(luò)技術(shù)的發(fā)展,互聯(lián)網(wǎng)技術(shù)在教育教學(xué)領(lǐng)域中的應(yīng)用也日益廣泛與深入。網(wǎng)絡(luò)教育、網(wǎng)絡(luò)課程、在線教學(xué)與網(wǎng)絡(luò)學(xué)習(xí)環(huán)境的設(shè)計(jì)已經(jīng)成為當(dāng)前國(guó)際教育界的熱門話題,這在一定程度上有效地推動(dòng)了網(wǎng)絡(luò)教育教學(xué)的發(fā)展。在教育的形式方面,網(wǎng)絡(luò)教學(xué)視頻已是教師進(jìn)行網(wǎng)絡(luò)教學(xué)和學(xué)生進(jìn)行在線學(xué)習(xí)的最主要數(shù)字資源。在當(dāng)前網(wǎng)絡(luò)課堂教學(xué)中,不管是一般的課程教學(xué)網(wǎng)站還是目前熱門的MOOC或SPOC課程等學(xué)習(xí)平臺(tái),播放的學(xué)習(xí)視頻一般都是教師的講授視頻與教學(xué)課件的相互配合。學(xué)習(xí)者觀看這樣形式的視頻資源就相當(dāng)于將傳統(tǒng)的教學(xué)形式搬進(jìn)了視頻中,學(xué)生不是學(xué)習(xí)的主動(dòng)者,依然是知識(shí)被動(dòng)的接收者。同時(shí),學(xué)習(xí)平臺(tái)中視頻播放的單一形式,導(dǎo)致學(xué)習(xí)者只是簡(jiǎn)單地觀看視頻并沒有強(qiáng)烈的學(xué)習(xí)興趣。因此,在線學(xué)習(xí)的學(xué)習(xí)效果沒有得到進(jìn)一步的提升,這對(duì)高等教育的網(wǎng)絡(luò)化、數(shù)字化帶來很大不便。本課題的研究首先對(duì)國(guó)內(nèi)外在線學(xué)習(xí)平臺(tái)上的學(xué)習(xí)資源中視頻的播放情況,以及學(xué)習(xí)者在學(xué)習(xí)過程中的視頻播放流程進(jìn)行了調(diào)查,例如:學(xué)堂在線、慕課網(wǎng)、華文慕課和中國(guó)大學(xué)MOOC等知名學(xué)習(xí)網(wǎng)站。筆者通過文獻(xiàn)調(diào)查了解分析了國(guó)內(nèi)外針對(duì)于在線視頻播放過程中采取的行為和技術(shù)手段,并發(fā)現(xiàn)其存在的不足與缺陷。通過HTML5+jPlayer技術(shù)手段,筆者對(duì)在線學(xué)習(xí)中視頻的播放進(jìn)行了控制,再加上沉浸主義理論、在線學(xué)習(xí)反饋理念和聯(lián)通主義學(xué)習(xí)理論中關(guān)于在線學(xué)習(xí)平臺(tái)的研究,筆者設(shè)計(jì)并實(shí)現(xiàn)了一個(gè)在線學(xué)習(xí)平臺(tái)。本系統(tǒng)模塊可以基于網(wǎng)絡(luò)學(xué)習(xí)平臺(tái)使用,也可以單獨(dú)為網(wǎng)絡(luò)視頻控制提供服務(wù)。系統(tǒng)開發(fā)與實(shí)現(xiàn)架構(gòu)是依據(jù)了 Strus2 MVC分層設(shè)計(jì)思想,并使用了 Mysql作為系統(tǒng)平臺(tái)的數(shù)據(jù)庫(kù)。前端頁(yè)面采用HTML5+jQuery+jPlayer庫(kù),通過自身設(shè)計(jì)與實(shí)現(xiàn)控制視頻播放的邏輯算法,系統(tǒng)最終實(shí)現(xiàn)了基于HTML5視頻控制的在線學(xué)習(xí)系統(tǒng)模塊。此外,視頻播放邏輯控制的實(shí)現(xiàn)算法也可以為移動(dòng)端的應(yīng)用提供參考價(jià)值。
[Abstract]:With the development of modern computer network technology, the application of Internet technology in the field of education and teaching is becoming more and more extensive. The design of online teaching and online learning environment has become a hot topic in the international education circle, which to some extent has effectively promoted the development of online education and teaching. The online teaching video is the most important digital resource for teachers to teach online and students to learn online. In current network classroom teaching, no matter it is a general course teaching website or a popular learning platform such as MOOC or SPOC courses, Generally speaking, the learning video broadcast is the cooperation between the teacher's teaching video and the teaching courseware. The learner watching this kind of video resource is equivalent to moving the traditional teaching form into the video, and the student is not the active learner. At the same time, the single form of video playing in the learning platform causes the learners to simply watch the video and have no strong interest in learning. The effect of online learning has not been further improved, which brings great inconvenience to the networking and digitization of higher education. And the process of playing video in the process of learning, such as online classroom, Motule.com. Through literature investigation, the author analyzes the behavior and technical means adopted in the process of online video playback at home and abroad. By means of HTML5 jPlayer technology, the author controls the playback of video in online learning, plus the theory of immersion. The author designs and implements an online learning platform based on the theory of online learning feedback and Unicom learning theory. The system module can be used on the basis of network learning platform. The system development and implementation framework is based on the Strus2 MVC hierarchical design idea, and uses Mysql as the system platform database. The front-end page uses HTML5 jQuery jPlayer library. By designing and implementing the logic algorithm to control video playback, the system finally realizes the online learning system module based on HTML5 video control. The realization algorithm of video playback logic control can also provide reference value for mobile applications.
