When I was younger I quite wanted to be a Children’s TV presenter, a la Andy Peters or Philip Schofield. Things didn’t quite pan out that way, however, recently I have found myself starting to watch more and more Children’s TV shows. In this post I rank those that I have seen, giving a brief critique of each.
- Sarah and Duck: this is a totally wonderful programme. They lead a bit of a crazy life. But what Duck can do with just the narrowing of his eyes shows that dialogue can be greatly overrated and the animators are true masters of their craft. Supporting characters abound, all with well-developed back stories; Umbrella, Bug, The Shallots, Scooter Boy, Flamingo and John, Plate Girl, the Narrator, Bag Lady, Bag, Donkey, etc are all superb. But Cake takes the biscuit, his two episodes are genius. And the “It’s your birthday today” song has overtaken Happy Birthday in my estimation. Quite a feat! Wonderful entertainment from a young girl and her mallard.
- Thomas and Friends: a childhood favourite that has withstood a makeover without losing its charm. Always a good watch with plenty going on. Ok, Thomas is actually a bit of a loose cannon and pretty much every character has their faults (don’t we all?), but their desire to be a really useful engine is something we should all aspire to. FWIW, James is my favourite. I like his red paint and vainglorious ways. Similarly, Gordon’s phrase “it’s not wrong, we just don’t do it” has become a useful addition to my vocabulary when I really want to annoy someone.
- Charlie and Lola: it’s always a pleasant experience watching this programme. Right from the theme music onwards it is spellbinding stuff. A feel good favourite.
- Fireman Sam: I thought I would hate this new rendering of an old classic, but it has won me over. Despite Sam’s head being ridiculously oversized, I can look past this anatomical-anomaly to enjoy the highjinx of Pontypandy. Special mention goes to Norman for being a one-boy accident zone, but who always sees the error of his ways and apologises in the end.
- The Adventures of Abney and Teal: two rag dolls living on an island in a lake in a city. Yet again the supporting characters enrich the programme to make the sum greater than its parts; Neap, the Poc Pocs, Bop and Toby Dog (please, please learn another tune!) all add a sense of whimsical fancy.
- Nelly and Nora: two Irish youngsters living the fun life in a caravan park. Another whimsy that is wholesome and good.
- In the Night Garden: this is another crazy show. One thing I cannot unsee is Iggle Piggle resembling former Prime Minister, David Cameron. The Pontypines are great fun (my father can’t stand them for some reason, interestingly he also has no time for the Pinky Ponk airship either) and spotting the Wottingers is a rare delight. Amazingly it apparently cost £14.5 million to produce 100 episodes. That seems a lot to me!
- My Family: (not the BBC sitcom) this gives the chance to gawp at the life of another family. It is a simple premise and one that works very well.
- Peppa Pig: this is like crack cocaine for the under fives. I’m not sure how the programme makers do it, but children seem to go absolutely nuts for it. Yes, Peppa is a bit bossy / naughty and the moral high-grounding can get a bit much after a while, but they’ve obviously found the recipe for success. And Mr Skinnylegs is such a good name for a spider.
- Baby Jake: I literally have no idea what is going on in this programme! This much I know, there’s a baby called Jake in it.
- My First: another Ronseal of a show, we watch a child experience their first [insert activity here]. An example, opening a bank account. A must for aspiring accountants everywhere.
- Bob the Builder: unlike Fireman Sam, this new imagining leaves me cold. Just hearing Bob drone on about his projects is enough to make me fall asleep. Pretty much every story involves one of the team screwing up a building job by ignoring the plan or disregarding instructions. Usually the miscreant is Scoop, a yellow digger, with a penchant for taking short cuts with dire consequences. The average episode starts with building something, someone ignore the plan, the thing they built falls down, the person who ignored the plan apologises, Bob says “never mind” and they build it again but this time properly. It’s a good job that Spin City seemingly has no other builders, because Bob’s crew are so incredibly inefficient and wasteful. I watch this programme in silent resignation. Dreadful.

By sex, I mean male or female*. Apologies if the title has been clickbait to potentially something very different.
Recently I have been thinking about sonographers and ultrasounds, specifically those undertaken in health authorities that allow pregnant women the chance to find out if their bump is a little boy or girl during the 20 week scan. While I am aware that such a practice always comes with the caveat that it is not 100% accurate, I wondered just how accurate it is. Does the sonographer keep a record of how many foetuses they correctly detail the sex of? Or are they just a point of prediction with no way of following up whether the information provided was correct? My thoughts are that they never actually find out whether they are right or wrong. Why would they unless they encounter the mother again?
I wonder how many parents have an extra surprise on the arrival of their little bundle of joy? And what is the training in identifying the sex of foetuses? I might guess they use still and moving library images from 20 week scans (and dare say it would be easy to find out the exact details of the training, but that’s not quite the point of this extended-idea). It would be a very interesting experience to be expecting a girl and then finding you are welcoming a little boy into the world, or vice versa.
My rather loose point is that it is sometimes very difficult to see how something one does actually turns out in the long run if there is no-one looking at outcomes much further down the line. Whether it’s the accuracy of determining sex of a foetus or anything else. For example, how do we actually know that anything a teacher does actually affects a pupil or class or year group? More importantly, what happens 5, 10, 20 years down the line? Do you produce “lifelong learners” or is it just a trendy thing to say? Longitudinal studies with regular follow ups can help identify trends or patterns, but are very much for the long-term. It seems to me too many people in education are concerned solely by the short-term. And don’t get me started on association football managers, the epitomy of short-termism! Seeing how things pan out isn’t necessarily the same as letting things drift, but perhaps this is the problem? More thinking (by me!) is required on this topic, but an interesting chain of thought nevertheless.
*Last term I was asked to present to my school’s Diversity Society on sex and gender. A fascinating area, but for me sex is biological – due to chromosomes and therefore primary and, to some extent, secondary sexual characteristics – whereas I believe gender is a social-construct and inherently subjective. However, chromosomal and developmental abnormalities is a topic to itself. As is gender and I am certainly open to interpretations that are non-binary. Both are perhaps best revisited in further detail in the future.
I’m trying to be a little more innovative with my posts, so am running with a series of random extended-ideas. These will start with a cursory thought that may or may not be connected to education, so a little more off-the-cuff. It might also prove to be less earnest than many posts I produce.
In no particular order, here are the posts:
This is a follow up to a post on essential reading for anyone who is taking Biology A level. In short, I have already listed (in no particular order) The Red Queen, The Immortal Life of Henrietta Lacks, Life Ascending, The Epigenetics Revolution and Darwin’s Island as books a Sixth Form biologist should read.
Following the last post, a colleague and I debated the particular merits of each book and also the titles that were left out. The original was always meant to be the first in a series, so here I am with one more recommendation.
The Selfish Gene by Richard Dawkins
Perhaps the most controversial omission from the original post was Professor Richard Dawkins. To be quite frank, I would be more than happy to add any of his back catalogue to this list. The man is a real inspiration in terms of the ground-breaking work he so eloquently summarised in The Selfish Gene. Seeing organisms as “survival machines” for the genetic material that is inherited from parent to offspring is absolutely key to the kind of ‘big idea thinking’ required to truly understand the discipline. My 30th anniversary edition sits slightly battered on a shelf in my office, bought when I started teaching to replace the even more battered version I had at university.
Dawkins’ gene’s eye view of evolution totally changes the focus of how we look at biology. Additionally, its style is accessible for pre-undergraduate students, although concentration and a sharp mind are useful to keep up with the witty and energetic prose. Don’t just take my word for it. Here’s what W D Hamilton, widely recognised as one of most significant evolutionary theorists of the twentieth century, had to say:
“This book should be read, can be read, by almost everyone. It describes with great skill a new face of the theory of evolution.”
Still not convinced? Why not watch this short clip, The Selfish Gene Explained, from the Royal Institute to whet your appetite for the book. Following this, dive head first in to the book. Keep doing this and you will be amazed at just how much you can get from The Selfish Gene. Just like the Necker cube mentioned in the preface to the second edition, you will see different perspectives on the theory of evolution via natural selection.
This post is specifically for the CIE Biology International A level qualification. What follows are my attempts to help guide students to do the best they can in the advanced practical skills exam, Paper 3. However, the information below is no substitute for proper revision and the dedicated practise of actually carrying out a variety of biology experiments. Additionally, I would strongly recommend you use the past papers section of CIE’s website to sit as many “mock” practical exams as possible.
Command words in a question
- Say what is going on, e.g. the trend or pattern of results.
- When describing data, always use units if appropriate (e.g. °C or cm3).
- Say why a trend or pattern is occurring.
- When explaining data, always link it to A level Biology.
Although describe and explain are the most common command words, you might find yourself answering questions with any of the following:
- Calculate: use mathematics to find an answer. E.g. mean, percentage, percentage change, rate, ratio, etc.
- Measure: use a suitable measuring instrument to take a reading, being sure to include units after the numerical answer.
- Suggest: there is no one correct answer; you should look through the information you have been given for some clues.
Even more rarely you might find one of the below command words in a question:
- State: give a brief answer – maybe one word or a phrase.
- Define: give a definition – these should be concise.
- Determine: explain how you could take measurements and calculate an answer from these measurements (e.g. in an experiment).
How many answers should I give?
- If a question states “identify two” then only the first two responses will be marked.
- If a question states “record observable differences” then all responses will be marked.
How great is the risk?
If a question asks you to “state the hazard with the greatest level of risk” for your practical, do not choose one you deem to be low risk. E.g. warm water in a thermostatically-controlled waterbath set at 30°C, is a hazard that is low risk and so would not gain a mark. A better answer would identify a risk that was either medium or high, e.g. hydrogen peroxide is harmful to the skin. The key is to identify a hazard with “the greatest level of risk”.
Deciding independent variable values
Give five values at roughly even intervals (e.g. every 5°C or 10 cm3) when deciding what values to use for your independent variable. Always use units if appropriate (e.g. °C or cm3).
Recording numbers and drawing tables
Do not go past one decimal place when recording the results from your experiment, usually whole numbers are fine. And always use units if appropriate (e.g. °C or cm3).
- Put the independent variable (IV) on the left and dependent (DV) on the right.
- Draw a line between the top row and the body of the table, e.g. underline the IV and DV.
- Use the full name of the IV and DV (e.g. temperature of hydrogen peroxide and time taken to rise).
- Only use units in the headings, not the body of the table (e.g. temperature of hydrogen peroxide / °C and time taken to rise / s).
- Record results for at least five values of the IV.
- Results should show the pattern or trend theoretically expected of the practical.
- Use whole numbers.
- Record results for two trials and calculate a mean average.
- The mean average should be recorded to no more than one decimal place.
Identifying sources of error
Think carefully about your experiment, where might there have been an error? E.g. if you are looking at colour changes this is subjective and will be a source of error. Ensure you state the error and the reason it occurred.
Describe how an element of a practical can be investigated.
- Use five values.
- State how these five values will be made, e.g. if the IV is concentration of enzyme, “use simple or serial dilution” or if it is temperature “use a thermostatically-controlled waterbath at 20°C, 30°C, 40°C, 50°C and 60°C”.
- You will normally use data that is given to you in the paper.
- Put the IV on the x axis, DV on the y axis.
- Use the full title from the table to label each axis, e.g. “initial rate of catalase activity / s-1“.
- Always use units if appropriate (e.g. s or seconds but not sec).
- Look at the values and use a logical scale. E.g. a scale of 0.06 or 0.04 for every large square of graph paper is not logical. However, a scale of 0.05 is logical.
- Each plot will be checked to see whether it is accurate to within half a small square of the graph paper. It is recommended you use an x mark to do this.
- There should be no labelling within the area of the graph.
- Lines will be judged for their quality*.
- Ensure lines are not too thick, as the quality of each one will be judged*.
- Bars can be touching. However, if you chose to leave gaps the gaps must be evenly spaced.
- The horizontal lines at the top must be perfectly straight, parallel to the x axis.
- Quality of lines will be judged*.
- No ruler straight lines for your diagram: nature is not straight!
- No labels or writing within the drawing.
- Label only what is asked of in the question.
- Do not draw in anything that you do not see. E.g. smaller organelles.
- The diagram should be at least 60 mm wide at its greatest width.
- There should be no shading.
- There should be no cells in plan diagram. Do not be tempted to draw them in!
- Use the correct section of the slide. This will be in the instructions of the questions, but make sure you actually draw what it wants you to!
Diagrams of cells
- Cells should be at least 50 mm at their greatest width.
- Draw exactly the number of cells stated in the question.
- Do not include half cells. The questions always state “whole cells”.
- Cells should not overlap but may be abutting (e.g. touching each other or sharing an outermost line).
- Always show your working and the steps you take to come to your answer.
- Always show units, but do not mix units. E.g. not 1 mm and 50 µm.
- When converting units, show the conversion. E.g. 1 mm to µm: 1 x 1,000 = 1,000 µm.
- Try not to go beyond one decimal place, or the same level of precision as is given in the question.
- Give ratios to the lowest common denominator. E.g. 168:58 should be 84:29.
Comparing observable differences using a table
- Organise the table as three columns; one for the differences and two for the samples. E.g
- Underline the headings and divide the columns as per the table above.
- If asked for differences, do not give similarities!
- Differences would ideally be “X is thick” and “Y is thin”.
*Quality of lines
Each line you draw for a graph or drawing could be judged for its quality. E.g. whether it has been drawn by a sharp pencil as a thin and continuous line. This is really important as you don’t want to lose silly marks for not sharpening your pencil!

Recently I have enjoyed a ‘healthy’ discussion with a colleague about rewarding work in exercise books and reward systems in general. Although we disagree about what the reward should ultimately be, we both agree that many systems just peter out and become ineffective as a student progresses up the school. The house points / merits / commendations that work so well in the early career of a secondary school student hold no currency later on, neither with student nor teacher. Currently there is a lot of thought from the pastoral leaders at my school to try and get the best system for throughout the five years of KS3 and KS4. Reading through the blurb from other schools I can’t help but wonder whether they too suffer from the ‘Year 9 dip’; chatting with acquaintances is an easier way to get closer to the truth. Certainly a policy on rewarding work should not be merely window dressing to look good on a website or prospectus. It needs to be applied consistently and to actually engage the students, motivating them to improve and contribute to the school community in a worthwhile manner. This is where I hope we are heading.
Returning to the opening sentence of this post, the ‘healthy’ discussion on how to reward students centred on whether confectionery was a good choice of reward. Despite my musings on Jaffa Cakes, it will surprise very few people to know that I was very much against this… Not only on physical health grounds, but also the mental association of success and chocolate. I strongly believe this is not a healthy coupling to make. As part of a healthy balanced diet and with regular exercise I am all for sweets, chocolates and other unhealthy foods. In fact I am quite the chocoholic, but I do not eat chocolate to reward myself for having done something good. To equate success to sweets is a terrible policy.
PS: I am also against the random bringing in of cakes for Sixth Form classes, something that seems to have grown in popularity. In the past my classes have received short shrift when trying to bring up the subject of ‘cake Fridays’. This year my timetable has me teaching two different Upper Sixth classes after lunch during period five and six (of a six period day) on Friday. When the inevitable questions was posed I have relented, to an extent. We now have ‘fruit Fridays’, instead of cake someone brings in enough fruit to satisfy our postprandial cravings. Happily one class has totally gone for this, we’ve had blueberries, satsumas, grapes aplenty. While I am sure students would prefer cake there needs to be a good deal more ego and less id, to paraphrase Dr Freud’s suspect theory.
PPS: Just so no-one thinks I am a totally miserable so-and-so, the header image is a lovingly made Chocosaurus birthday cake for my son. It would be a bit much to have just carrot sticks and grapes!
Day two started with the Brexit news hanging over conversations at the Festival of Education. It was a relief when the sessions started and thoughts were turned squarely to teaching, learning, assessment ands way from the uncertainty. As with yesterday’s post what follows is a brief précis of what I enjoyed most.
Slow Education – featuring Mike Grenier, Ciran Stapleton and Rhiannon Morgans. The latter two being Head and Head of Sixth at St Joesph’s School, an establishment that is working with Grenier’s school to bridge partnerships between Sixth Form students. Slow Education sees schooling as a social exercise with a clear and defined philosophical side, moving away from the puritanical to seek a greater depth of engagement. Mike’s ferment belief that education is above and beyond measurement is one that I totally agree with in theory; I would certainly love the chance to discuss it with him further in the future. Back to the session, the real stars of the show were two Sixth Formers from St Joesph’s who spoke eloquotently and extolled the virtues of their tutorial collaboration. A great start to the day.
Questioning with Toby French – highlighted a common issue when questioning pupils; often when it is successful the teacher has to do all of the work. Why try to draw something out of a student – who quite clearly doesn’t know the answer – when you can just tell them?! His colour coded questions based on an idea from Dylan Wiliam is something I’ll try in my classroom next week. Ultimately Toby suggested we shouldn’t ‘not’ ask students questions, but we should change what we ask. He also amused me greatly by sharing an anecdote about a meeting on picking a type of font in response to my question about shifts in culture.
Martin Robinson asked “what type of teacher are you?” Having been privileged to host Martin at a recent conference it was great to hear him without the pressure of organising the event! Do we want a meritocracy? Are we happy to have the deserving poor? Are we being taken away from the core purpose of education? Are we cogs in a machine? Is bueauracracy the driver in our schools? All these questions were posed in the tradition of dialectic and made immensely interesting in Martin’s session. We were encouraged to “be heroic, be wild” as a final call to arms. Interestingly speakers from both of the sessions I had previously attended were present, which was very much standing room only.
Tom Sherrington started with the point that these events sometimes lack a real focus on classroom teaching. A fear that enivatably comes from the sheer scale of EdFest and the variety of speakers. However, his session was great and shared the Teaching and Learning priorities of his school, Highbury Grove. From ideas that staff should know about (even if they don’t agree with them!) to thoughts on behaviour, there was certainly something to take from his presentation. By the end Tom had achieved his goal of evoking “the heat of everyday practice”.
Another great day and I hope the ideas continue to mature in my mind over the final few weeks of the academic year. These two blogs on the Festival of Education will act as a fixed point to refer back to, as well as a rambling summary of my experience here.
