A discussion of strategies for managing social bookmarking teaching and learning activities (using del.icio.us)

Many educational benefits are attributed to the activity known as social bookmarking. Whilst re-iterating these benefits this article will discuss and offer a solution to the task of managing social bookmarking learning activities.

Three reasons why teachers and students should join a social bookmarking site

1. Accelerated Knowledge Acquisition: Through personally tagging, building a network of informed users, through subscribing to specific tags and from connecting with like minded taggers, you will acquire phenomenally fast access to resources of interest. What this means is that your access to knowledge is increased dramatically, your knowledge and understanding will develop more quickly and your awareness of current issues will keep you up to date and at the forefront in your field.

2. Portability and Flexibility: Because social bookmarking websites can be accessed anytime from anywhere as long as you have an internet connection the opportunity to tag bookmarks, retrieve information from saved bookmarks and keep up to date with the tagging activities of your network is increased dramatically compared to the option of saving your bookmarks to a location bound home or office based personal computer.

3. Easy and fast searching and retrieval of Resources: your own bookmarks, your network members bookmarks and the bookmarks of all members of your social bookmarking site can easily be searched by keyword or tag to retrieve previously bookmarked resources or find new resources of interest.

4. Easy organization and categorization of resources means teachers can offer improved support for students. Students have a mechanism to assist themselves in self directed study. Tagging allows bookmarks to be organized in a number of different categories, not just one as is the case in a hierarchical folder type set up. Bundling of tags is an additional organisational tool

5. Connections: Tagging can reveal other individuals that have bookmarked the same resources as you and who may therefore share the same interests. Apart from adding them to your own social bookmarking network it could lead to collaboration, support and access to other knowledge resources external to the social bookmarking activity.

6. Sharing your access to knowledge: For teachers’ resources can be made easily available to students and colleagues either through the social bookmarking site itself, embedding bookmark links into web pages or by using RSS Feeds. Students can do the same and learn these valuable skills for other areas of their life e.g. work, family, hobbies.

Individual Motivation
In my view initially the use of a social bookmarking tool such as ‘del.icio.us’ is essentially a tool for the individual to have a convenient location to store and categorize bookmarks for their own benefit, thus enabling 24/7 access from any internet connected computer. In relation to the wider world of the web, the individual tagging of bookmarks has unwitting, unplanned and uncontrived social and group benefits.

As the concept and features of social bookmarking have evolved it is possible that some individuals develop a collective consciousness and the tagging of bookmarks may become more of a social act as well as just for individual benefit. That said, as there is no overwhelming reason or obligation to conform to a tagging standard, then it would seem that primarily the tagging of bookmarks is for individual gain. Which I guess is how it should be for it to be a genuine folksonomic tagging system (that reflects the true tagging intentions of its members). Tagging habits may change overtime depending how influenced an individual is by the rest of the tagging community.

Social Bookmarking in relation to teaching and learning activities
As part of their definition Phillip Jeffrey and Samia Khan from the Human Communication Technologies Lab describe social bookmarking as a “non-hierarchical and inclusive process of groups cooperating ad hoc to categorise and share information using reader-created (e.g. del.icio.us) tags” They add “This non-hierarchical concept of tagging to classify and share is called a folksonomy.” (Jeffrey and Khan 2005) .

The differences between social tagging and collaborative tagging are highlighted by comparing the definition of collaboration; “to work together, especially in joint intellectual effort” and the definition of social; "living or disposed to live in companionship with others or in a community, rather than in isolation" (ASC 2007) to emphasise that collaborative tagging has more purpose and is perhaps a better way to describe the tagging that will occur in a contrived teaching and learning activity.

Whilst informal social bookmarking has all the benefits mentioned previously, more formal teaching and learning social bookmarking activities bring a number of additional issues relating to secondary tasks such as for example reorganisation and retagging of bookmarks, reviewing and critiquing bookmarks or discussion of tagging strategies. The specifics of various teaching and learning tasks are for another time, the focus of this article centres around two main issues; 1) Task management and 2) A single account strategy.

Scenario and Issues to address

The number of students, the intent of the task and the time in which to do the task will all add to how a task is organised and facilitated. As an example we shall use the following scenario, and assume that the task is completed using the ‘del.icio.us’ social bookmarking site.

If we imagine a scenario where a teacher has 150 students to teach. In order for the individuals in a group to develop some kind of bond and to give focus to the learning activities, the group of 150 is split into 15 groups of 10. Tagging, organising, reviewing and critiquing tasks can ensue from here. The two issues of interest are:

1. Activity Management: How can a teacher maintain and control a number of different groups attempting the same social bookmarking activity.
2. Single Account Strategy: How can this group work be achieved without the need for a separate group account being setup.

Perhaps the first issue is more obvious than the second, but I think both issues are closely related in developing a satisfactory strategy for both teacher and student. I’ll take the second issue first as I believe this is at the heart of a potential problem. When social bookmarking moves into the arena of teaching and learning the emphasis moves onto group work, collaboration and the requirement to complete specific tasks. For social bookmarking the formation of a separate group account seems an obvious and easy solution to organize and control the task. But is this either satisfactory or necessary for the student? Should a student have to work with more than just there own personal social bookmarking account? For the student it is a major inconvenience to interrupt their surfing activity to have to switch from one account to another. For the teacher it is not so much of an issue as one way or another they need to isolate the bookmarks into 15 separate groupings rather than one big group,

Solutions

Options include:
1. Separate group account – Students all login and contribute to the group account with bookmarks that are specific to the purpose of the learning activity. (teacher can still view activity without having to log into group account, by subscribing to RSS feed)

2. Tag as Individuals; View in separate group account – teacher to create a network of the users in the group. Teacher and users can tag in their own account, and also view the group network tags through ‘del.icio.us’ or RSS feeds. (bookmarks not relating to the learning activity will also appear)


3. Tag as Individuals View in separate group account - using the ‘FOR’ function
students add bookmarks to their own allotted groups whilst tagging in addition to tagging for themselves.(RSS feeds do not appear to be available for this feature)

4. Tag as Individual with unique identifier tag - We can ask the student to include as one of their tags a unique identifier such as the institution name plus a course code and then a group number e.g DMUabcd1234_G1. Then set up a subscription to this tag. (note: there is potential for misspelling, but both teachers and users can access all bookmarks through ‘del.icio.us’ or RSS feeds)

5. Tag as Individual with unique identifier tag. Use a separate group account – Same as four above, but isolates specific learning activities away from other subscriptions teachers or students may have. (So for a teacher that could potentially be capturing many groups subscriptions in one place, they can look at all subscriptions ensuring bookmarks not relating to the learning activity will not appear)

With all of these options (except the FOR function) viewing of contributions would be best achieved by looking at the network, subscriptions or specific tag pages, either
a) Directly within the ‘del.icio.us’ network or
b) By setting up an RSS feed on the ‘del.icio.us’ tag.

Conclusion
If we start from the premise that no extra group accounts are to be setup and that students will only need to tag as individuals using their own ‘del.icio.us’ account then that rules out option 1. We now have to decide what of the remaining four options seems to be the most suitable to manage the activity of fifteen groups of ten. As I would prefer to view any bookmarks via an RSS feed reader this would rule out option 3. Option 2 with the possibility of unrelated bookmarks being included is also ruled out. For similar reasons I would rule out option 4 as this could also include unrelated subscriptions.

Option 5 will allow students to use their own individual account and tag bookmarks with no restriction on how they tag, other than adding a unique identifier tag.
There is no major burden for the teacher by setting up a separate group. The teacher can use the group account and its subscription feature to collate unique identifier subscriptions for all 15 groups, whilst having the flexibility to flick easily to anyone of the smaller subgroups to view specific group unique identifier subscriptions. These benefits can apply to students as well.


What do you think?

Do you agree with the strategy, have you any other ideas in mind? Can you see any problems or inaccuracies with the five options mentioned.

Bonus Point!
For archival purposes bookmarks for each groups subscriptions can be exported to a separate html document.

Food for thought!
Tagging strategies – if you have a blog post on a particular subject that you want to publicize then tag your own blog to circulate to your network and for those people that might subscribe to a particular tag.

Hey Wiki! Your so fine you blow my mind. Hey Wiki

After setting up a very basic wiki, I have just started to take a look at the use of wiki's in education. My findings are summarized below and are based on reading the following 4 web documents and listening to a skypecast (link below).

1. Naomi Augar, Ruth Raitman and Wanlei (Nov 2004) Zhou “Teaching and learning online with wikis” http://www.ascilite.org.au/conferences/perth04/procs/augar.html
2 Joe Grohens and Norma Scagnoli (Spring 2006) . “Uses of Wikis in Teaching”
http://www.cites.uiuc.edu/edtech/teaching_showcase/brown_bag/archive/spring06/grohens_scagnoli.html
3. Chien-min Wang Turner, D. (April 2004) “Extending the wiki paradigm for use in the classroom” http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=1286462
4. Steve Hargadon blogspot (Aug 2006)
“Exploring Wikis in Education with Vicki Davis and Adam Frey”
http://stevehargadon.blogspot.com/2006_08_01_stevehargadon_archive.html including recording of “The uses of wiki’s in education” skypecast
http://educationbridges.net/k12opensource/wp-content/uploads/wikis.mp3

After reading educators feedback on these various websites, seeing how wiki's are currently being employed on the web and listening to an interesting skypecast led by Steve Haregedon it does seem that a wiki in education does indeed have the capability to metaphorically blow your mind. It would appear to be a very powerful tool to engage the students and produce good quality, useful content much more quickly than a student working alone.

Through my reading and skypecast listening I know have a basic understanding of the point of a wiki. With a little more knowledge about the features, functionality and role of wiki’s in education I intend to setup new wikis and collaborate on existing wiki’s to further improve my understanding of the educational uses of a wiki.

Differences between Wikis and Blogs
Before I summarize my findings I’d like to pick up on a couple of interesting points made by Vicki Davis (2006) on the difference between wiki’s and blogs. According to Vicki she explains that the way she looks at it:

1. A wiki is more concerned with facts and a blog is more about opinions and
2. It's easier to contribute to a wiki rather than a blog.

Although I don’t think this will or can be strictly applied, these are two interesting points which may be a nice neat starting point in distinguishing between the uses of the two types of technology.

The Wiki
A wiki is basically a very simple and easy to edit web page. It is designed for group collaboration. Users can either read the content of or add content to a wiki document page.

Vicki Davies (2006) a teacher at Westwood Schools in America and a strong advocator of wikis predicts that wiki’s will become the hub of education in the future. Vicky sees wiki’s as the toolbelt that holds all her technology learning tools together, the central focus of what she teaches. Joe Grohens (2006) supports this view in that he uses wikis as a complete course management system.

Augar, Raitman and Zhou (2004) describe wikis has having 2 different writing modes, or styles of usage:

1. Document mode, where writers create collaborative documents written in the third person and
2. Thread mode, where contributors carry out discussions in the wiki environment by posting signed messages. Others respond leaving the original message in tact and eventually a group of threaded messages evolve.

Pages of wiki can also be described as having two states a ‘read’ state and an ‘edit’ state. To edit a page users click an edit button. Editing a page on most wiki websites is made easy by providers who provide editing toolbars. If no editing toolbar is available then users need to understand wiki language syntax to edit a page (although not too difficult, the edit toolbar makes it a lot simpler for users)


Wiki Features and Functions
The main features and functions that you will find in a wiki include:

1. Authentication – By participants logging into a wiki any addition’s to content can be authenticated providing accountability in terms of who said what and when. [with authentication participants may also have use of a signature tool to move into edit mode automatically inserts the participants wiki username. The signature tool is often hyperlinked to a personal user page which helps students to build an online identity in the wiki environment.
2. Backup and Retrieval of earlier wiki entries.
3. Tracking – Usually in the form of a recent changes page where student participation can be assessed.
4. Notifications by email of any recent updates so that users can check on any new material that is of interest to them and change information if incorrect.
5. Uploading of images and other media

Strengths of Wikis
The basic strengths of a wiki are:

1. Simple and easy to use
2. Easy to learn how to use.
3. Excellent for collaboration and collaboration over time
4. Easy to share.
5. Simple technology – only need internet access and a web browser.
6. Ability to compare two different versions of a wiki

Student Benefits
For students the benefits of a wiki include:

1. It is a student centered environment, students can be involved in the structure and the content.
2. Everyone in a class can access the same version of the work.
3. Previous versions of the work can be recovered
4. Easy to correct mistakes
5. Because it is simple and easy to use, barriers to contributing are removed.
6. Accessible from any computer allowing students to work on assignments at any time.
7. Group work skills can be improved.
8. Steady incremental improvement in both the organization and the content of a document.
9. Social interaction is enhanced. A sense of community can be built up.
10. Information easily disseminated.
11. Information easily stored.
12. Collaborative production of documents. This can build a body of knowledge wider and quicker than an individual. The social and technological interaction can enhance learning. Steve Haragedon (2006) believes that “collaborative efforts are generally better than individual”.

Teacher Benefits
For teachers benefits include:

1. Easy place to post assignment instructions.
2. Easy place organize course material.
3. Wiki’s can be password protected
4. Better than discussion boards, easier to administer according to Joe Grohens
5. Easy for students to submit there work
6. Keeps a log of revisions of student work

Educational Uses
The educational uses of a wiki will be wide and varied some uses that have come to light during my reading include:

1. Summary of Lessons
2. Collaboration of notes i.e. sets of documents that reflect shared knowledge.
3. Dissemination of important information
4. Build up core content and Topic base e.g. creating a book
5. Pre Class planning e.g. Ask students ahead of time what they want to study and shape the content around that.
6. Students can supply feedback to each other
7. frequent revisions and drafts due to the inherent simplicity of wiki technology.
8. Exchange of ideas.
9. Facilitates group interaction. E.g see Auger, Raitman and Zhou’s example idea of an introductory icebreaker.
10. Individual Assessment projects?

Usage Guidelines
An important aspect not to be overlooked is a clear set of usage guidelines, Augar, Raitman and Zhou (2004) advise from their study that these should be short, simple and written in a positive tone. There guidelines “encouraged users to be considerate of others and be active and friendly in their wiki posts”.

Issues
Despite all the positive sounding noises, Scagnoli points out a number of challenges and issues that need addressing. These include plagiarism/ copyright issues, monitoring can be difficult and problems of outside editors should a public wiki site be used.

Conclusion
Hopefully this blog although not capturing everything relevant, touches upon the main aspects of a wiki from an educational point of view. My focus now will be to work and participate in wikis and to identify specific, practical exercises that enhance student learning.
