Making students see the bigger picture is difficult but crucial. Using overview early in the course, say, when you introduce a new topic or Unit is an ideal way of getting them thinking abou the 'story' of what you're doing. Re-visiting these overviews are also important so students can see where they are heading, particularly if you are teaching a thematic or synpotic approach; how will students grasp why peasants across 1855-1956 link with Russian 'empire' or 'nationalities'; or how policing in the 1750s connect with the thinking of the period.

We work hard at creating activities that makes overviews matter to students - getting them thinking about how the smaller picture 'slots in' with the bigger.

Here's an example of encouraging them to consider just that. What do you think? How do you do it? How important are overviews and bigger pictures in your subject?

Pecha-Kucha, or 'chatter' is a method of presenting using visuals which was first introduced by two Australian architects in 2003 who sought to keep presentatiosn tight and focused.

The rules are simple:

• create a PowerPoint presentation, or using Keynote, with 20 images lasting for 20 seconds, as you tell the story in sync with the pictures. Your presentation will only last for 6 minute and 40 seconds. Slides will play automatically (panic!) so when the last slide has been shown it's all over... Nice and simple.

Give student a good topic ot theme which requires them to think about the bigger picture e.g. How did Stalin consolidate his power? They then have to use 20 images which demonstrate their understanding. The limitations imposed on them will enable them to focus on:

• evaluating the theme
• carefully select and rank which elements are the most significant to answering the question
• demonstrate clear judgment on on broad questions

Pecha-Kucha is a fantastic way of making it difficult for students to 'go deep' in their presentations - they will have to do that during their research. Also, their audience will have to 'dig deep' in order for them to see the bigger picture. The whole class will therefore improve their skills.

How could this method be used in your subject? It would be great to hear from you. Just click add new comment to explain what you do - after you've registered of course .
