Using Web 2.0 Technologies in Computer Science Classes

Using Web 2.0 Technologies in Computer Science Classes Lillian (Boots) Cassel1, Manuel A. Pérez-Quiñones2, Edward A. Fox2, Steven Edwards2, Manas Tungare2 1Department of Computing Sciences Villanova University 2Department of Computer Science Virginia Tech

Plans for the evening • Online Participation (Cassel) • Web 2.0 in Education (Pérez-Quiñones, Tungare) • Mashup and other examples (Fox) • Web 2.0 in CS 1 (Edwards) All URLs in slides are off tinyurl.com. Visit website for full URL. 2

Online Materials • All materials for the workshop are available at: • http://syllabus.cs.vt.edu/web20/ • Also, we have a Facebook group for the workshop • http://tinyurl.com/279jf3 3

SIGCSE is a vibrant community • Common goals, cohesive community, large conference, active mailing list • Yet, online sharing of educational materials has not really ﬂourished 4

Online participation • Do you share pictures online? (e.g. ﬂickr) • Do you write comments in Amazon products? Do you value the other opinions there? • How often do you participate in the SIGCSE mailing list? 5

If we build it, will you come? • How many of these do you use? Why? Why not? • ACM or IEEE DL • CITIDEL • SIGCSE education links • NCSTRL, CoRR, NSDL, ETD... 6

NSDL • NSF funded effort • Collections of resources and information for multiple disciplines (science, math, engineering, technology) • Support for all educational levels (K-gray) 7

http://tinyurl.com/2bnjdw Web 2.0 The Machine is Us by Michael Wesch 5 minute discussion on what it means and its implications for Manuel and Manas will do this section 8

Social Software... • ...enables people to rendezvous, connect or collaborate through computer-mediated communication [Wikipedia] • 55% of all American youth (ages 12-17) use some form of social networking site [Pew Internet & American Life Project, Lenhart 2007] 9

Features of Social SW • Goals: identify friends, resources, staying in touch, sharing interesting news... • Commenting features... support discussion, collaboration, exchange • Social tagging • Connections - friends, “following,” groups... • Syndication and embedding... • Mashups - use API to combine data into new apps10

Goals • Identify friends (facebook, orkut, friendster) • Education (citeulike, campusbug, carmun, koofers, rateteachers) • Share resources: movies (youtube), pictures (ﬂickr), status (twitter), bookmarks (del.icio.us, stumbleupon), news (digg, reddit), citations (citeulike), exams (koofers), slides (slideshare)... put site images/logos to make more graphical 11

Social Tagging • Free for all tagging, users pick their own tags Joe Mary • Social network gives tag_x meaning to tags tag_y tag_y • Joe receives as a url_a url_b recommendation url_b no ontology, no imposed classiﬁcation, why it works web2.0 video - who will organize this? you will. 12

Syndication & embedding • Syndication of content from one site to another 13

http://tinyurl.com/2xfrwb Mashups... • Combination of multiple applications • Google maps is a popular partner in mashups 14

http://tinyurl.com/28hkgo no hands on, demo only What is this group?

Facebook.com • Social network connecting • Pros and Cons for use in friends & groups classroom • Close communication among • Hands on: go to facebook and friends join the group for the workshop “Using Web 2.0 • Recommendations Technologies in your Computer Science Classes” • Application platform - build your own applications • http://tinyurl.com/279jf3 • Increases social capita of participants demo and join group 16

Twitter.com • Status (what are you doing) • Has been used in courses to service support “contextualized” teaching (teaching in the • Inform your friends, be moment) informed about their status • Hands on: Go to Twitter and • “Follow” friends, famous create an account, follow sigcseweb20 people, or single words • Updates can be received via • Send direct message by email, SMS (to your phone), d sigcseweb20 message etc. - no hands on - discuss education uses 17

YouTube.com • Video archiving and playback • HTML can be embedded in for community supported another page videos • Embed videos in your • TV, Movies clips, Seminars, lectures or website other user provided content • Example: • Search and you will ﬁnd: http://tinyurl.com/35sjgg http://youtube.com/watch? v=lXOyd68saIM • Hands on: Search YouTube.com for a visualization of some data • Add url to to facebook, structure (e.g. btree) automatically recognized - search for video of CS ed - include in facebook 18

citeulike.org • Bookmarking for references, • Example: with support to export to http://citeulike.org EndNote, bibtex, etc. • Supports “bookmarking” from popular cites, including ACM DL • Power of social browsing, recommendations - hands on - search for ACM paper - add to citeulike - ﬁnd other relevant papers - add to our citeulike library papers by fox, cassel, tungare, edwards, me 19

Koofers.com

Facebook Apps - show cat-space - key is to show facebook as platforms • Study groups • We are exploring a few possibilities... 21

Custom applications • Syllabus collection • Computing News, as a result of Google search • Google COOP 22

Wikis • Collaborative editing on the web without the need of anything other than a web browser • Allows creation and linking of pages • Give students the ability to collaborate on the creation of materials for class • Good uses in education, example: http://collab.dlib.vt.edu/runwiki/wiki.pl 23

Mashups • Are hybrid web applications that combine information drawn from various web sources • Simple example: • A library web page that includes a news feed • A professors page with list of books 24

Course Page Demo • A professor wants to offer a list of books on his course page, along with full bibliographic and up-to-the-minute holdings information about each book 25

Second Life • A 3D virtual world, created and maintained by users • Full economy, buy property, purchase goods, sell stuff, all virtual • Demo... 26

Steve will present this part Web 2.0 in CS 1 27

We need to rethink... education • Community of • Information spreads learners that go faster than we can beyond the classroom, control it major, campus, town • Collaboration take • Community of different forms educators ... • social interaction • Sharing of resources is exists both online the norm and ofﬂine 28

Implications for Education • the sky is falling, cheating is • Include social aspect in class rampant, we are doomed projects • Have a presence on facebook - make students know you are participating • Post some pictures to ﬂicker, movies to YouTube, slides to SlideShare, messages to Twitter • Make use of embedded content, rss 29
