I have to confess, this is on my bedside table having just picked it up last week, rather than an established part of my reference library. Making Sense of Secondary Science has already been useful as a guide to research showing what students really think. Knowing what ideas and misconceptions they have really helps to prepare for what you’re going to teach them. This is particularly true if you want to approach it by showing them – or even better, letting them collect – evidence which contradicts what they have always believed.

I think this book will get used more as I produce more detailed schemes of work to use in my school. I have often started topics by asking student what they think they know, and ocassionally by giving them part of the test to assess previous understanding. This is a step in a more research-based approach.

 After some specifically KS3 ideas, here’s one that can take you a little further. I was given The Resourceful Physics Teacher (by Keith Gibbs, but not currently available from Amazon or the Book Depository) by my friend Marion. She’s also a physics teacher and assured me it would be useful and it has indeed become well-thumbed.

The book includes the practical details, tangential suggestions, tips and tricks that help to turn a standard demonstration into something a bit more special. It also has explanations for teachers and models to use with students, and I would certainly recommend it for non-specialists wanting to get a few ideas as well as experienced or new physics teachers wanting to up their game.

While checking this post I’ve found he now runs a website with a load of usable content, http://www.schoolphysics.co.uk/, which I will add to my links as soon as I’ve had a proper chance to check it out…

Continuing the theme from yesterday, a time saver. I picked up a BBC KS3 Bitesize book, Check and Test Science. Each page has a summary of an idea, such as ‘special cells’ or ‘selective breeding’, which uses key words and simple diagrams. The bottom third of each page has questions to test what a student knows, which can be answered (or at least explained) by the facts above.

Again, the questions aren’t anything we couldn’t manage ourselves. The advantage comes when you’re short of time or low on inspiration. Numerical examples and specific chemical equations stop you from using the same, easy to remember versions each time.

As far as I can see, this book isn’t available many places new but finding something similar should be easy. I’m currently looking for something along these lines to use for KS4 topics, so please let me know if you have any recommendations.

As teachers, it’s really easy to end up reinventing the wheel. At my school, like many others, we have mountains of schemes of work, resources and worksheets. Like many other schools, I suspect, finding the best resources to use for any given lesson, at any given time, can be a challenge. For my KS3 students I often use a book I’ve had since my placement to help kick off lessons.

101 Red-Hot Science Starters is easily worth the fiver or so it costs. Organised by topic, the ideas are quick and simple to put up on a board, and include answers as well as differentiated outcomes. If you’re organised, you could put a series together on a powerpoint if you’re lucky enough to have regular electronic whiteboard access.

It’s not, I hasten to add, that you couldn’t come up with the ideas yourself. On the contrary, my book has many scribbled additions of my own. Instead, it’s that coming up with starters (or plenaries – many are versatile) takes time which most of us are short of. This gives me, I reason, another five minutes per lesson to plan a main activity.

Instead of one longer post, this week I’m planning to post five times, but much shorter. Let’s see how it works out.

I read all the time. What I read informs my teaching, from thrillers and other fiction to recent popular (and unpopular) science. However, there are some books I return to time and again which really help my lessons.

I have old copies of A-level revision guides for Biology, Chemistry and Physics, picked up for almost nothing in charity shops. Instead of the guides most of my students use today, these are not linked to one specific (and now obsolete) syllabus. Instead, they are arranged as a dictionary, with scientific terms listed in alphabetical order. I find them indispensible to dip into for quick and clear definitions, links to similar ideas, applications and simple line diagrams.

You can buy new copies (the Complete A-Z Physics Handbook, for example, is available at The Book Depository  for about £12) but for a teacher the old versions are probably as good, maybe better. If you find an extra copy, why not keep one at work and one at home?

Oh No! Not Blue Monday!

The bad news is, an incredibly bad bit of ‘science’ has once more reared its ugly head. The good news is, the story in the Daily Telegraph here is a fantastic opportunity to teach our students an awful lot about science…

Hilarious update – Cliff is now claiming we should all ignore it and be happy instead, says a different article in the same newspaper!

First of all, it’s based on previous work by Cliff Arnall, who might reasonably be described as a media-whore for repeatedly wasting our time with this sort of inanity. In fact, this is yet another use of his non-science as reported last year by Ben in his excellent column. Cliff has form. The Telegraph really should know better. I tell my students that although not totally reliable, Wikipedia is a good place to start looking for information. That the newspaper have ignored this wealth of evidence suggests they think their readers are idiots.

Apart from anything else, it doesn’t seem that he is currently employed by the University they link him with. Instead he is a self-employed life coach and pilot. Ahem. He managed to find time a few months back to suggest you could work out the formula for the perfect toy. How does he get it all done.

I actually wonder if the Telegraph got all the ideas – some more sensible than others – from the same press release, or if they just decided to save themselves time by cramming as much lousy science and tenuous correlations as they could think of into the same article. I’m actually going to put their suggestions in a list.

  • chocolate is good for you, say Venezuelan endrocrinologists – or, more to the point, the same scientist who has been pushing this idea for the last fifteen years or so.
  • have flowers in the house or garden. Some specific species are mentioned and I think I know why – they happen to be on offer through, yes, the Daily Telegraph
  • use bright morning light, says Vicki Ravell, a sleep researcher who should possibly make her conflicts of interest – she is a paid speaker for a company who make devices designed to simulate bright morning light – clearer in this sort of story. 
  • Cancel meetings, says a business coach (and, as it happens, member of the newspaper’s ‘panel of experts’ for the Readers’ Clinic). Presumably the Telegraph staff have a Monday meeting they’d like to skip. Who doesn’t?
  • Bite a pencil to make you smile
  • Book a holiday – interestingly, it is Richard Wiseman who is quoted here, despite the fact that Cliff Arnall is usually sponsored himself by holiday companies to promote this story each January. The previous ‘biting a pencil’ idea is also referenced in Wiseman’s (excellent) book, 59 Seconds,as is the following:
  • Imagine your own death (says another author)
  • Eat fresh fruit and herbs, specifically those advised by Cherry Chapell, a PR hack who has also written a few books – she is an expert in that she has a collection of Grandma’s Remedies published. Presumably these are what we would call ‘old wives tales’ or ‘anecdotes’.
  • Eat chilli, which among other effects, destroys mitochondria. Hopefully I don’t need to point out that this effect is presumably not relevant when eating it or we would all be in trouble – and if it was, it would be spectacularly bad advice. There seem to be some suggestions that chilli helps prevent cancer as it kills off cancer cells. How healthy cells are not affected presumably remains a mystery.
  • We should eat with fat friends as this prompts us to eat less, according to a report from last year, also reported in the Telegraph and many other newspapers.
  • Listen to music while we exercise to try and get more out of it. Hmm. Well, I have to admit, running in the morning is slightly less painful with loud rock playing (Lost Prophets anyone?), but I found this quite a tenuous link. Until I found out that the expert in question has a compilation CD out to help people try and get more out of exercise. So that would be the science bit then.
  • Be nice to people at work and see if the effects get passed on. Well, can’t hurt.
  • Get more sleep because it will help you lose weight, said a study a few years back. Although how this – and many of the other things – will help you in the course of a single bad day is beyond me…

I can’t help it – let’s do the maths.

Five suggestions that are effectively adverts, six if we count ‘book a holiday’ and four research items that are, quite possibly, a few years old and irrelevant to daily life. Out of thirteen ideas.

Do I need to write this as an equation for people to take my opinion seriously?

Revising Online

(Updated 1st May to fix broken link)

I’m a big fan of paper and pen, I have to admit. I can’t read a non-fiction book without a pencil in my hand, ready to add notes in margins. Revision should, I feel, start by writing out some ideas, perhaps headings or main nodes of a concept map. But many students disagree and some find it very helpful to use resources online, either ‘live’ or downloadable software. This post will list a few ideas to get you started – please let me know, hypothetical reader, if you can suggest any more – and in time this will become a page all of its own.

Concept/Mind Maps

If you like mind mapping, there are many resources you could check out. One company which likes the idea of visual, rather than written notes and revision is Model Learning These different layouts may be useful in a range of circumstances, to explore, explain and revise links between concepts. I also like the information the Open University have made available at  Visual Techniques for Revision. You might also want to check out http://www.mind-mapping.co.uk/

Flash card junkies

You can’t go far wrong with a stack of 5×3 index cards and a pen. If you want to turn this into an electronic equivalent, I currently have three suggestions – but they all require a little work.

Quizlet is a website that allows you to define your own flashcards, linking any two ideas together. They can be definitions, translations, symbol and unit, whatever. Once defined, they can be shared with other users (one of my long-term projects will be to start making sets of these for my students to use) and turned into tests, games and other activities. You may find some useful sets there already and if not, making them yourself is a good first step in revision. 

Memoriser is a freeware utility (translation: free to download and use) which lets you define the facts you want to learn, questions you want to answer or anything else. It can then be set to run in the background while on a computer, asking you random questions at preset intervals.

The third is something you may already have, but it’s an interesting application of Powerpoint. You can save a slideshow as a folder of jpeg (image) files. Many mobile phones can now store and display such files, and you can often run them as a slideshow. This means a revision powerpoint – ideally clear slides with small amounts of text – can be saved to your phone and played back at odd moments, in bus queues or while waiting at the dentists. Most students won’t carry around revision cards, but will need death threats to be parted from their mobile phone.

I’m sure there are many more available – please drop me a line if I’ve missed out your favourites!
