【摘要】：隨著互聯(lián)網(wǎng)的發(fā)展以及edx,Coursea和Udacity等開(kāi)放式網(wǎng)絡(luò)教學(xué)平臺(tái)的推廣,互聯(lián)網(wǎng)教學(xué)逐漸興起并廣泛普及�；ヂ�(lián)網(wǎng)教學(xué)中學(xué)生獲取知識(shí)的一個(gè)主要媒介是互聯(lián)網(wǎng)課程中的教學(xué)視頻資源。然而,當(dāng)前的互聯(lián)網(wǎng)教學(xué)輔助平臺(tái)中存在一個(gè)明顯的不足:學(xué)生無(wú)法及時(shí)針對(duì)教學(xué)視頻細(xì)節(jié)在云端記錄并分享筆記或?qū)で髱椭�。這將會(huì)影響學(xué)生對(duì)視頻形式的教學(xué)內(nèi)容的理解,也不利于形成優(yōu)質(zhì)的學(xué)習(xí)生態(tài)系統(tǒng)。由此,設(shè)計(jì)了一種面向Chrome瀏覽器的視頻云筆記工具,并采用了HTML5,Node.js,MongoDB等關(guān)鍵技術(shù)對(duì)其進(jìn)行了實(shí)現(xiàn)。該工具能夠針對(duì)互聯(lián)網(wǎng)教學(xué)視頻資源的細(xì)節(jié)內(nèi)容記錄、發(fā)布筆記并在云端共享,有利于學(xué)生對(duì)視頻教學(xué)資源中細(xì)節(jié)的整理、理解、討論和最終掌握;同時(shí)該工具可以根據(jù)學(xué)生人群在使用工具的過(guò)程中產(chǎn)生的數(shù)據(jù)對(duì)視頻內(nèi)容進(jìn)行一定程度的解析,挖掘視頻教學(xué)資源中的關(guān)鍵點(diǎn),從而降低學(xué)生獲取關(guān)鍵知識(shí)的難度,輔助學(xué)生的學(xué)習(xí)過(guò)程。最后,進(jìn)行了相關(guān)的實(shí)例研究,結(jié)果證明了所提出的分析設(shè)計(jì)方案的可行性和有效性。
[Abstract]:With the development of the Internet and the popularization of the open network teaching platform such as Udacity and Coursea, the Internet teaching is gradually rising and popularizing. One of the main media for students to acquire knowledge in Internet teaching is the teaching video resources in Internet courses. However, there is an obvious shortcoming in the current Internet instructional aid platform: students cannot record and share notes or seek help in the cloud in time for the details of teaching videos. This will affect the students' understanding of the video form of teaching content, and will not be conducive to the formation of a high-quality learning ecosystem. Therefore, a Chrome browser-oriented video cloud note-taking tool is designed and implemented with the key technologies such as HTML5, Node.js, MongoDB and so on. The tool can record the details of the Internet teaching video resources, publish notes and share them in the cloud, which is helpful for students to organize, understand, discuss and master the details in the video teaching resources. At the same time, the tool can analyze the video content to a certain extent according to the data generated by the students in the process of using the tool, and mine the key points in the video teaching resources, thus reducing the difficulty for the students to obtain the key knowledge. Assist students in their learning process. Finally, a case study is carried out, and the results show that the proposed analytical design scheme is feasible and effective.
