Conceptual learning and the Diffen wiki

June 26, 2008 in Tools

I was recently asked to provide usability feedback on Diffen.com, which uses an extended implementation of Mediawiki to provide a customised form of wiki. As the name suggests, Diffen is built around the idea of differences and each of the site’s articles provides a comparison between two key concepts.

For example, I created a simple page comparing compare and contrast, two terms which often cause problems in ‘old world’ assessment. In the true wiki tradition, my brief article has been edited and substantially modified by others!

Each Diffen article has a comparison table which is a useful feature, although this is not available when you first create a new article. You can search for two different terms and create the page if it doesn’t exist. Users can rate the two terms and also hide or show similarities between them. The site does have Google ads but overall has a simple design. A few features are not always clear for the new user but it’s quick to learn how to use the site.

In the past I’ve found activities based around two apparently polarised opposites very useful as professional development activity. So I can see opportunities for interesting read-write learning activities based around exploring concepts such as Behaviourism vs Constructivism. It’s a pity that each article is limited to comparing just two concepts, but a nice feature is that characteristics are inherited – ie if you create a new article, the comparison table is automatically populated if one or both of the concepts are compared elsewhere.

Overall, Diffen is a great idea and I can see useful applications in my professional development workshops and elsewhere in education where conceptual learning is important.

Validation problem with Feedburner email subscription

June 17, 2008 in Tools

In an earlier post I described a problem with HTML validation of a WordPress site when inserting links using the WYSIWYG editor.

I recently enabled email subscription on my site and inserted Feedburner’s code on my front page. Now I find this too causes a validation error – validator.w3.org doesn’t like the ampersand character (&) in the subscription link code:

http://www.feedburner.com/.../emailverifySubmit?feedId=123&loc=XYZ

The suggested fix is to replace the ampersand with & but unfortunately WordPress promptly turns this back into an ampersand, so it still won’t validate.

The work-around is to remove the &loc=XYZ entirely from the end of the URL – Feedburner doesn’t seem to mind. I guess the problem is that this will default to an English language subscription form at Feedburner… perhaps another example of how English language is dominant in the online world!

Maybe I need to stop worrying so much about validation and just pretend it doesn’t matter…

Helping learners write and think with a wiki

June 16, 2008 in Tools

A tool for thinking

In my professional development activities with teachers I often build in opportunities to learn using wikis. For many, it’s the first time they’ve edited a wiki so these activities provide useful exposure to the technology. But for me the key benefit is that wikis provide a tool for learners to organise their thinking as a key stage in writing, publishing and collaborating.

Read-write matrix screenIn an earlier post I’ve talked about the benefits of read-write learning in professional development.

See also the read-write matrix of web 2.0 tools for learning.

Since I like to focus on the cognitive benefits of wikis, I try to avoid spending too much time on how to use the wiki. I also like to keep participants focused on the thinking aspects of writing rather than the more mechanical aspects. In other words, I don’t spend time on the features which are more related to ‘making text pretty’, but I do spend time on features related to ‘organising thoughts’. In fact, I like to eliminate anything which gets in the way of the thinking process at this stage.

Features which support thinking

In practice, this means that once learners know how to go into edit mode, they need to find out how to create a link to a new page very quickly. And since unexpected new pages and links get in the way of the thinking process, I turn off CamelCase linking if possible and focus on using square brackets for links. That’s quick and easy to demonstrate and learners can be creating a multi-page wiki resource in just a few minutes.

If we’re using Mediawiki, headings are important since they provide structure to the page through the automatic table of contents. In other wiki software where a heading is primarily a formatting feature, I don’t spend time on this.

Lists (ordered and unordered) are also very useful for organising thoughts, so that’s something else which I tend to demonstrate reasonably early on.

Tables are another strategy for organising text – unfortunately the wiki markup for creating tables tends to be confusing for learners. Where the wiki software has a WYSIWYG editor inserting a table is fairly straightforward. But if you’re using Mediawiki then a tool such as Shawn Douglas’s Excel-to-Mediawiki converter might be useful.

Of course, once the writing process is further down the track, learners do want to ‘pretty up’ their text and that’s perfectly valid – that’s when ‘just in time’ learning has its place! In fact, learners mostly work the formatting stuff out for themselves anyway – if the wiki has a WYSIWYG editor the toolbar is very familiar. If they have to use wiki markup, I show them how to get to the editing help page and leave them to it.

Holistic alignment model for planning innovation

June 6, 2008 in Innovation

In the education sector, adoption of new technology or pedagogical approaches is often undertaken without a comprehensive analysis of the relevant factors. For example, the potential benefits of the innovation are often considered in isolation from the risks or drawbacks. Implementing an innovation based on the glowing description of a vendor or a one-eyed enthusiast often leads to disappointment!

The Open Access Newsletter site relies on gathering only positive stories about open access, not the negative ones. While this approach might be well-justified and valid for the newsletter’s purposes of influencing policy, it’s not necessarily a good model for practitioners implementing change.

Why affects How

In working with educators to plan and implement innovation, I’ve found that the perceived or expected benefits of an education innovation are closely linked to how the innovation is implemented. A similar link exists between the risks or drawbacks of the innovation and the way it is implemented. Now this may sound obvious, but it’s surprising how often this aspect is not well considered. For example, I’ve seen an innovation such as the introduction of self-assessment to a programme implemented in such a way that its benefits were minimised and the risks and drawbacks maximised.

In other words, the benefits (why) and risks need to be aligned with how the innovation is implemented, at both a strategic level and a practical level.

In addition, it’s important to consider the context of the innovation, including factors such as the distinctive characteristics of the organisation, the programme and the learners. For example, actual benefits in one cultural setting may work in opposition to the specific strengths of the organisation in another cultural setting and undermine its effectiveness – the innovation can cause damage rather than bring benefits. In analysing organisational characteristics, aspects of an appreciative inquiry approach can be very useful to balance an analysis of the ‘gaps’.

Holistic Alignment Model

Through my work with various education organisations I’ve developed a model which I’ve found useful. Because it focuses on considering the whole picture and aligning the various factors, I’ve called it the holistic alignment model. Despite the grandiose title it’s very much a work in progress, and feedback is welcomed. As well as a description of the factors to consider, there’s a suggested process for helping establish the alignment.
