e-learning 2.0: All You Need To Know

http://www.readwriteweb.com/archives/e-learning_20_all_you_need_to_know.php

Written by Richard MacManus / June 22, 2007 1:54 AM / 34 Comments

One of the strongest, but least hyped, uses of web 2.0 technologies over the past couple of years has been e-learning.

We've covered this topic extensively on Read/WriteWeb - and so we're pleased to bring you this overview of e-learning 2.0, including the leading web apps and sites in this niche, and predictions for its future.

In August Steve O'Hear (now last100 editor) wrote an introduction to e-learning 2.0. He noted that teachers and students are embracing web technologies such as blogging and podcasting. Although not designed specifically for use in education, these tools are helping to make e-learning far more personal, social, and flexible.

According to Steve, the traditional approach to e-learning has been to employ the use of a Virtual Learning Environment (VLE), software that is often cumbersome and expensive - and which tends to be structured around courses, timetables, and testing [examples listed below]. That is an approach that is too often driven by the needs of the institution rather than the individual learner. In contrast, e-learning 2.0 (as coined by Stephen Downes) takes a 'small pieces, loosely joined' approach that combines the use of discrete but complementary tools and web services - such as blogs, wikis, and other social software - to support the creation of ad-hoc learning communities.

Examples of e-learning 2.0 apps and websites

edublogs.org and wikispaces.com are two examples of blog and wiki resources for e-learning. Steve's post includes many other examples of edu-blogging, podcasting, media sharing and social networks. There are some interesting web apps for students popping up, for example a collaborative note taking app called stu.dicio.us and the ReadWriteThink Printing Press - which enables users to create a newspaper, brochure, etc.

elggFor an in-depth look at one of the leaders in this space, Steve profiled Elgg - a social network for education. This is an excellent example of how web 2.0 is shaping e-learning. Elgg is social networking software designed especially for education - built from the ground up to support learning.

Described by its founders as a 'learning landscape', Elgg provides each user with their own weblog, file repository (with podcasting capabilities), an online profile and an RSS reader. Additionally, all of a user's content can be tagged with keywords - so they can connect with other users with similar interests and create their own personal learning network. However, where Elgg differs from a regular weblog or a commercial social network (such as MySpace) is the degree of control each user is given over who can access their content. Each profile item, blog post, or uploaded file can be assigned its own access restrictions - from fully public, to only readable by a particular group or individual. Click here for an insightful interview with Elgg's founders.

Note that this type of e-learning social network is similar to "smart" social networks, in which you can put access controls around your personal details, so that only people you trust can see them. Facebook, imbee, Vox, and Multiply are all examples of smart social networks.

Another great example of an e-learning 2.0 app is ChinesePod, which we profiled in November. ChinesePod teaches Mandarin over the Web. It uses podcasting, RSS, blogging - and other Web 2 technologies - to teach Mandarin Chinese. The business model is surprisingly simple - subscriptions to language-learning materials. This complements the free offerings - basically, the Mandarin podcasts - very nicely. For example, if you want to dive into learning Mandarin straight away: select one of the episodes, plus you can participate in the discussions. The first level subscription is called 'Basic' and gets you a PDF transcript of the podcast. If you want get really serious about learning Mandarin, sign up to the premium subscription service and receive learning resources such as Review Materials and Lesson Plans.

The community aspect of ChinesePod shows what can be done with web 2.0 technologies in e-learning. Check out the Community page - which has a forum, wiki, blogs, photos, rss feeds. All the usual pieces, but each has a practical purpose. The wiki has extra links and information, the forum is well-used by users, the photos are lovely (of China), and there are a lot of great rss feeds to choose from.

Google, Microsoft, Apple, IBM - active in e-learning 2.0

What else is out there currently in Internet-based education software? Well for a start, the Internet BigCos all have products in the e-learning segment. Google offers the free Google Apps for Education (includes Gmail, Chat, Calendar, Page Creator, start page). Microsoft has a range of education products (including live.com hosting/email and potential groupware for education), and Apple offers free podcast hosting for education (iTunes U). IBM is also a player in the education sector.

Google seems to be particularly active in education, amongst the Internet companies. It has Google for Educators, described as "a platform of teaching resources". Also its Google Enterprise Professional program has at least one education provider - Blackboard become the first member of the program to focus primarily on educational institutions.

Not to mention that online office products can be used to enhance collaboration in an education setting. Google Docs & Spreadsheets for example. In effect, the BigCos are able to leverage their current product range and promote them to schools.

Collaborative E-learning Systems

As well as blogs and wikis, there is a class of e-learning 2.0 software that is more of a platform product. These are referred to as collaboration systems and examples are Elgg, Nuuvo and Digication. As Digication's Jeffrey Yan explained in January, e-learning 2.0 tools are often promoted by educators in a grassroots manner. Which when you consider the usual hierarchical academic setting, is an interesting trend. Jeff told R/WW there is a community of users who support these tools and "their approval/disapproval with features, functionality and direction can make or break a [e-learning] company."

As for the near future of collaborative systems, Jeff Yan says that blogs, wikis and podcasts will start to merge with more educationally focused systems in 2007.

Traditional Learning Management System (LMS)

Also known as Virtual Learning Environments (VLE), examples are Blackboard, Moodle and Sakai (the latter two are open source) As we hinted at above, the big commercial software like Blackboard is very 'old school' and doesn't have much focus on the community aspects of learning. They're expensive and are generally seen as clunky and difficult to use - not unlike traditional Content Management Systems in enterprises (Vignette, InterWoven, et al). They also have a lot of features that most teachers and students don't want or need.

However there are some newcomers that are interesting - call them LMS 2.0 perhaps ;-) As well as Digication and Nuvvo, there is Chalksite and haiku LMS.

Conclusion

As this article shows, there is a lot of web 2.0 activity in the e-learning space - including from the big Internet companies like Google and Apple. The current era of the Web is all about two-way communication, collaboration and 'read/write'; and the classroom is an ideal place to utilize these technologies. In the comments, tell us some of the e-learning apps or experiences you've encountered.

Yahoo Pipes (Combine the feeds via Yahoo Pipes)



http://pipes.yahoo.com

http://abu.tw/2008/08/yahoo-pipes.html


Yahoo Pipes,自由度極高的 RSS Feeds 整合器,更強的是, Yahoo Pipes 不需要寫任何的程式碼,動動滑鼠把物件拉一拉組一組,一個自訂規格的 RSS Feeds 整合器就變出來了。

不過,Yahoo Pipes 難也難在不能自己寫程式,沒辦法自己動手去做一些小幅的微調,不過,基本上都可以靠物件兜來兜去完成所想要的功能。各個物件也都有範例與說明以及其它人做的已經做好 Publish 出來的 pipes 可供參考。

我想像中我要的聯播列表長這樣:
  • [部落格A] 文章標題1
  • [部落格B] 文章標題2
  • [部落格A] 文章標題3
  • [部落格C] 文章標題4
  • [部落格A] 文章標題5
簡單來說,有個部落格標題作為標題前綴,然後依發布的時間排序。


Yahoo Pipes 最粗略地用物件表達就是像這樣:
Thinking in Yahoo Pipes 初步構想
它吐出來的資料就像這樣:
  • 文章標題1
    內文描述(item.description)
  • 文章標題2
    內文描述
  • 文章標題3
    內文描述
  • 文章標題4
    內文描述
  • 文章標題5
    內文描述

可以看到,我們有幾個 Fetch Feed 是極為相似的,只是抓取的來源不同,以及我可能分別要給它們不同的標題前綴。所以,異中求同,我建立一個物件 AbuFeedCore 來專責處理抓取資料及處理標題的動作。


物件 AbuFeedCore 需要給三個參數:
  1. Feed Title : 標題前綴
  2. Feed URL : 資料源位址
  3. Item Count : 想要的資料筆數
Yahoo Pipes AbuFeedCore
動作很簡單,就是把 Feed 資料讀進來,紅框部份的 Regex 物件就是最主要的,以正規化表示來處理標題字串成為想要的樣子。有興趣研究正規化表示式的,可以參考這篇「Regular expressions in Perl」。再來,依發布時間反向排序然後取回指定的資料筆數,這樣就完成了取資料源資料的核心物件嚕。

再來,我只想要我的聯播內出現標題(item.title),所以,想要把內文描述(item.description)過濾掉,所以我做了一個 AbuFeedTitles 物件來處理這個動作。

物件 AbuFeedTitles 的資料來源是倚賴先前所建立的 AbuFeedCore 物件,故同樣需要給三個參數:
  1. Feed Title : 標題前綴
  2. Feed URL : 資料源位址
  3. Item Count : 想要的資料筆數
Yahoo Pipes AbuFeedTitles
可以看到變數其實是拿去餵給裡面所加入的AbuFeedCore 物件,取回資料之後,再把內文描述(item.description)用 Regex 來清掉所有的內容,這樣,吐出去的資料就是純標題的列表嚕。

前面都是準備工作,現在要把它們兜起來了。成立一個像當初構想的一樣的物件 AbuFeedCollection

Yahoo Pipes AbuFeedCollection
因為大部分的工作都已經透過前兩個物件處理掉了,所以這邊整個介面很乾淨清爽,它只要負責把所有收到的資料整合之後,再做一次發布時間的反向排序,這樣就可以產生來自各部落格最新的文章列表了。

再來,Yahoo Pipes有提供各式各樣的發布方式,可以把產出來的資料以各種方式掛到想掛的地方去,或是直接用閱讀器訂閱也行。
Yahoo Pipes Use the Feeds

Yahoo Pipes 這個服務真的蠻令人驚艷的,整個UI以及操作的感覺,真的是把 Web Programming 提升到一個境界。不過,想當然爾的,它有點挑瀏覽器,算是小小小小美中不足的地方。

兩個小小提醒,如果有編碼的問題,比方說是餵中文的 Feed,結果吐亂碼出來的這種腹瀉症狀,可以先餵給腸胃出嘞名的強壯的 FeedBurner 先消化一下是個解決問題的好方法。再來,就是在拉那些物件去組出想要的功能的時候,初心者要多注意輸出與輸入的資料型態會讓挫折感少些,比方說它要吃 String 的就別塞個 item 給它,漸漸玩上手之後,就可以多用點心思在物件的設計上,把事情做完之餘,也可以想想怎樣做得更好。

蘋果展開iTunes U計畫_蘋果日報 March 4,2006

陳宜君╱綜合外電報導】

美國蘋果電腦公司憑其iPod數位影音播放器和iTunes音樂網站,稱霸數位影音市場,現在又展開擴大版圖最新行動,廣邀全美各大學與教育機構加入其iTunes U服務,將課程講授內容的podcast聲音檔案及其他教育資料,上傳到各校在iTunes的子網站,供人下載。

蘋果2001年推出iPod至目前,已售出逾4千萬台。該公司1年多前就和史丹福等6所美國大學合作,展開iTunes U(U為大學university的縮寫)計劃。學校利用網路教學,並非創舉,不過隨著數位影音檔案下載的普及,將手持式影音播放器應用於教育,已成為數位時代的新潮流。

為各校量身訂做網站

  將教師授課內容數位化供學生下載,有助複習課業,但部分教授擔心,這會讓學生產生鬆懈心理,導致缺課率越來越高。

  蘋果提供針對各校量身訂做的軟體與子網站,方便各校師生將podcast、有聲書和影像檔案等資料,上傳到由蘋果負責維護的伺服器內儲存,並讓各校將過去使用的系統與iTunes子網站整合,俾便師生沿用原有的身分識別代號與密碼登入專屬iTunes子網站。校方可自行決定各檔案是否限定特定人士下載,抑或對一般大眾開放。


學生可隨時隨地複習
  密蘇里大學新聞學院去年夏季加入iTunes U之前,就已開放師生透過校內網站上傳或下載課程的podcast檔和其他教育資料;加入該計劃後,其師生可利用蘋果提供的免費軟體與服務,連結至該學院的專屬iTunes子網站,下載需要的資料。密大新聞學院表示,多數學生早已熟悉iTunes的使用介面,應用成效良好。

  密西根大學牙醫學院去年秋季加入iTunes U計劃。該學院副教授強森(Lynn Johnson)表示,將課程內容數位化的構想來自學生,錄下教師授課內容並製作成數位檔案的工作也由志願負責的學生一手包辦,計劃推出至今相當成功,學生可隨時隨地複習上課內容。


iTunes U服務
●費用→免費
●對象→與蘋果電腦合作的全美各大學或教育機構,目前已有6所大學,包括︰
 ◎布朗大學
 ◎史丹福大學
 ◎杜克大學
 ◎威斯康辛大學麥迪遜分校
 ◎密西根大學安納堡分校牙醫學院
 ◎密蘇里大學哥倫比亞分校新聞學院
●內容→參加學校可設置各校的iTunes網站,將課程內容的podcast數位聲音檔案及其    他影音檔,上傳至各校網站,並決定檔案是否有下載資格限制。各校師生可透過蘋果電腦的免費軟體,連結自校iTunes網站下載檔案。

Wikispaces

在Wikispaces中每個帳號可以新增多個Wiki網站,在Wikispaces稱之為Space,其中Space的名稱是讓使用者自訂子網域的方式。 Space的權限分為三種,分別為Public、Protected及Private;Public及Protected為免費使用,而Private可以試用30天,之後就要收費,Public與Protected的差別在於所有人都可看,但Protected只有特定人才能編輯,Private則是只有特定人才能看及編輯。

但有特別提供給K-12教師使用免費。


Wikis for Everyonw.

Our full-featured wikis offer unlimited usage and our stellar visual editor. Check out our plans and pricing, and see why our customers call us the best wiki out there.


About Wikispaces

Who are we?

Wikispaces is run by Tangient which is Dominick Bellizzi, Jessica Brown, James Byers, Sarah Cove, Adam Frey, Debbie Guskin, Jeff Hanke, and Bisma Moon.

Since early 2005 we've been dedicated to building the world's easiest to use wiki service by listening closely to the ever growing Wikispaces community. We now host over 750,000 wikis for over 1,800,000 people and have products designed for the smallest classroom and the world's largest corporations and institutions.

Drop us a note any time at help@wikispaces.com or join our main discussion area. Welcome, and we look forward to hearing from you.

What's Important to us?

Simplicity

We're firm believers that wikis can be revolutionary tools for building communities. But most wikis are very engineer-focused: hard to use, buried under busy user interfaces, full of features only a geek could love. Wikispaces is our attempt to build a wiki that's easy to use and easy to adopt for all kinds of audiences. We've kept the tool simple so that you can focus on building content, talking with other members, and growing your community.

Community

The majority of tools that exist to publish content on the Internet are either one-to-many (e.g. personal websites, blogs, news sites) or short-lived (forums / message boards, FAQs, etc.). Wikispaces gives groups the freedom to publish pages that are long-lived, regularly updated, and built by many contributors. We give you the space to both publish and discuss content, without tangling the two together.

Openness

Wikispaces is built to work anywhere, anytime. All you need is a web browser and an Internet connection. Members can create pages and spaces without undue restrictions or rules. Guests can edit pages without creating an account. Wiki pages are fully internationalized, so you can contribute content in any language you like. We take care of hosting, backups, and upgrades so you don't have to. All of our services are free to try and we don't ask for any of your personal information up front. And our pricing is simple and clear.

Usability

Wikispaces is designed to be usable for everyone. We've built a visual editor that lets you see the layout and design of your page while you're editing it. No technical knowledge required. We also let you use wiki markup if you're so inclined. And we've made sure that Wikispaces is fast even in large communities with lots of activity

Service

Our customer service has been called "crazy amazing." That's because we're more concerned about helping you than doing anything else and because the people who respond to your email are the same people who built the service.

Thanks

First, thanks to all of the Wikispaces members who have taken the time to send us feedback, participate in the community, and generally kept us going.We also owe our thanks to a number of people for helping make Wikispaces possible: the teams behind PHP, MySQL, lighttpd, lucene, Brad Fitzpatrick and crew for memcached and mogilefs, and Mark James for his Silk Icons found in many of our themes.

Wikispaces for Educators
http://www.wikispaces.com/site/for/teachers

In January 2006, we decided to give away 100,000 free Plus wikis for K-12 education. We didn't set out with a grand strategy, just an interest in helping teachers with our easy to use wiki technology.

In September 2008 we gave away our 100,000th K-12 wiki. We know a good thing when we see it so we're giving away another 250,000 ad-free, private K-12 Plus wikis! All the features and benefits that normally cost $50/year - for free. No fine print, no usage limits, no advertising, no catches.

Thank you to all of you who have brought Wikispaces to your classrooms. Supporting the education community has been extraordinarily rewarding experience for us. You have made our work a pleasure and helped us to build a better service every day.

For more about our new offer, check out our blog post.
Try a wiki at your school now, and help us spread the word!

Sakai vs. Moodle | Zacker.org

http://www.zacker.org/sakai-project-vs-moodle

For IT directors at schools debating whether to use Sakai or Moodle as a course management solution, here is a side by side comparison. All signs point strongly towards Moodle kicking Sakai's butt and to the Mellon Foundation, Hewlett Foundation, and Sakai Partners wasting $6.6M.

在此篇的分析顯示,Moodle 遠遠勝過於 Sakai,但在這篇文章的回應上有各種不同看法,值得一看。

Sakai

Sakai is a set of software tools designed to help instructors, researchers, and students create websites for collaboration. Using a web browser, users choose from a set of features to create a site that meets their needs.
Here are some examples of websites possible to create using Sakai software:
  • A project director can create a website to make announcements and share resources, such as documents or links to other resources on the web.
  • An instructor can create a website that serves as an online discussion board for students to collaborate on an assignment.
  • A student can create a class website to work on and submit assignments electronically.

Sakai software is part of the Sakai Project (www.sakaiproject.org), a community source effort for creating open source collaborative tools for use in learning, research, and other types of distributed group work.

ELGG vs. Moodle - defusing a false dichotomy

http://www.edtechpost.ca/wordpress/2005/11/21/ELGG-vs.-Moodle---defusing-a-false-dichotomy/

http://www.unisa.edu.au/odlaaconference/PPDF2s/13%20odlaa%20-%20Anderson.pdf

I’ve had a few people come up to me at conferences recently and ask me to compare ELGG and Moodle, and choose between them as if they were somehow mutually exclusive. Indeed, even within the Moodle community itself there seems to be a bit of dismissiveness about what ELGG does, and the notion that with just a couple of twists of code Moddle can easily replicate its functionality.

Well maybe, but this is what excited me so much about the paper linked to above by Terry Anderson and the work he describes taking place at Athabasca University. I had the pleasure of seeing Terry present on this recently and wish I could link to those powerpoints as I think the illustrate the point I’m trying to make better than the article does, but what is exciting for me is that Terry and Athabasca are putting together a large, production environment in which Moodle and ELGG will seemingly co-exist quite nicely, thank you very much, and take care of different problems. Hopefully I am not going to mangle this too much, but as I understood it, Moodle was being positioned to handle conventional ‘course management’ problems like the delivery of content, assessments, discussions. In Athabasca’s case (and I’d argue in all of our cases, but that’s another post) they also have to deal with a continuous uptake model, where instead of cohort-based programs they also have very much self-paced programs with differing start times. Thus they are using ELGG as one of the ways to build community “between” the space of courses, community that is formed not because of one’s membership in a pre-ordained group or cohort but out of your interests. Sounds to me like a job for social software!

Can Moodle support similar ad-hoc community formation across course (and even institutional) boundaries? Maybe, and it sounds like we will find out fairly soon through upcoming releases. And bully for them if they can. But what I love about ELGG is that it is built from the groud up around the user and their connections as they key focus, rather than on ‘courses’ or ‘content’ (I’m not trying to levy a criticism at Moodle here as I like it very much as well). Far from being only a ‘blogging’ tool or a ‘eportfolio’ tool, what excites me about ELGG is that it is becoming a social networking ‘framework’ (o.k. you can dispute that term as much as you like) that while it has initially focused on tools to create blog posts and share files, isn’t interested in restricting you to only its blogging tool (and why would it? RSS anyone?) and is looking at a whole set of other interesting apps (Calendaring? Synchronous tools?) that are also of intrinsic value but become even more useful if people can use them with other semantically related users.

Should elearning providers be looking to one single tool to provide all of these aspects and more? Maybe. Right now though, the best bet seems like trying to get the best solution possible through a set of provisional measures. Personally, I’m more interested in making these and others co-exist, and seeing if we can get the integration between them to be more than lame-ass ‘pointing to their URLS’ or simple single sign-on; if instead we see if we can get shared identity happening across a number of these services in a way that takes identity mean more than your username and password. - SWL
