ITC in the classroom: Padlet


After recently attending the Science and Maths Specialist Conference at the University of Huddersfield (#Hud13) I have decided to try a few new IT solutions in the classroom. This week I tried Padlet (formally called Wallwisher) free at http://padlet.com


(in this image I have removed the names of learners)

I tested Padlet on five on my classes (none of who had used it before) and overall it worked very well. Padlet is a web-based service allowing a number of users to 'write' messages onto a 'wall' simultaneously; the teacher sets up the wall and the students access it via a hyperlink. The students can edit their own entries but not those of their peers, the teacher can amend or delete any entry if logged on.

After some initial confusion as to what to do and how to post entries and pictures (which I largely let the learners solve for themselves, encouraging them to explore and help each other as necessary) they enthusiastically accepted the concept. Indeed we spent rather longer on the activity than I had initially planned, they seemed to get a lot out of it.

One of the five classes had a less mature attitude that the others and initially some silly messages were posted however after a warning they soon managed to produce some good work. Minor difficulties notwithstanding, all the groups quickly took to the concept and managed to do some useful research for their assignments. Ad-hoc collaboration between learners spontaneously developed and the finished Padlet walls were downloaded and posted onto the VLE for future reference.

Padlet is definitely something I will be using regularly form now on.

Tip: always log on yourself during the session so you can control the wall dynamically.

Next week I will be trialling Google Forms

The tv portrayal of a science lesson on evolution



I don't normally pay too much attention to what my daughter watches on CBBC but was surprised and pleased this morning to see a fairly realistic and sensible portrayal of a biology lesson about evolution on the teen werewolf series Wolfblood followed by an explanation of the limitations of using school microscopes to analyse blood samples. Most tv dramas (irrespective as to whether they are aimed at children or adults) would I suspect have taken the easier route of portraying the 'science' inaccurately to drive the plot along. Not seen any more of the series so not sure if this particular episode is representative, but a hopeful sign.

On... Fossil Detectives

Fossil Detectives, BBC4, Thursdays, 19.30. 


Fossil Detectives comes from the serious but low-budget end of BBC tv's science output - presenter (the excellent Dr Hermione Cockburn), location, simple graphics, interview with expert, that's it. Not that this is a bad thing as it leaves plenty of space for science content. In the two episodes broadcast so far we have had a good basic introduction to the formation of fossils, places they can be found, and of both modern and historic interpretations of fossil evidence. 


Both episodes have also included interviews with David Attenborough (future episodes will feature interviews with musicians and fossil fans Billy Bragg and Alex James). These possibly sit slightly oddly within the style of the rest of the programme and perhaps could have been made into a stand alone programme of their own. This is not to say that the interviews have been uninteresting in any way. David Attenborough is always good value and here he is talking about one of his childhood passions, fossil collecting. 


Less spectacular than Earth: the Power of the Planet (currently getting a re-run), Fossil Detectives is nonetheless an informative and intelligent yet still accessible series. I look forward to the remaining six episodes and hope for an eventual repeat on BBC2 which should bring it to a wider audience.
