In the current climate, with exams being cancelled and our attention being turned to what will happen over the coming weeks, there is an increasing burden to set or adapt work that is suitable for home use, especially for KS3.
As a result I'm making available my entire current KS3 scheme of work and lesson resources. We use One Note to deliver our lessons normally, so we're already in the fortunate position of being able to work online as matter of routine. However, anyone can take any of the lessons out of these One Note files and use them for themselves. As usual, all that I ask is that you do not modify and then upload these resources anywhere else - you are free to use them, modify them yourself but not to upload modified versions. I've combined all the lessons in to one single notebook which you can download here.

My friends, we find ourselves in uncharted waters. I've spent this week telling all my students that, no matter what, their exams would absolutely be going ahead and we have to carry on our preparations as normal. I said this because... I genuinely believed it couldn't possibly happen any other way.
I watched the statement to the house by Gavin Williamson (the Education Secretary) earlier, nodding along at the expected closure of all schools from this Friday. As the cancellation of exams was announced I genuinely watched open mouthed. It cannot be overemphasised how unprecedented this is. I cannot think of another time when examinations have not gone ahead - even during wartime, education continued to function and children took final examinations. I am genuinely devastated and upset for those of you who have come on what is an intense journey together over the last two years. We've been through it all - the daunting prospect of 20,000 word reports and coding challenges for Year 13 students, the endless repetitive practise of past papers to hone our exam technique and ensure that everyone recieves the recognition their ability deserves. We've been through the lows of mock exams where some of you may have felt like you were staring at a sheer cliff face with no obvious way of climbing it when results came back far lower than you may have anticipated. Then there's been that slow dawning, especially in Year 11, that with the right focus, the right amount of dedication we were getting there. My Year 11 group this year have done things they never thought possible and please, understand this - you are an absolute credit to yourselves and I have recognised every one of your efforts. It has been so obvious the sheer hard work you've put in alone, with your families and together as a group and we've seen the fruits of your labour. In the last mock window your results all improved, you'd not just begun to climb that seemingly impossible cliff face, you were nearly over the top and in the clear. We've all put in so much of ourselves to prepare for what is undeinably one of the most significant points in any persons life. The process of taking your final exams and recieving those results is life changing and a defining moment for each student as an individual and to have that opportunity taken away is unimaginable. Whether you achieve "academic excellence" and sweep grade 9's across the board, or whether you walk away with a deep sense of unfulfilment and grades that you may not be happy with, it cannot be denied that those feelings set a course for the rest of your life. In some it will breed a renewed sense of determination to succeed regardless of what a piece of paper may say, in others it is a validation and vindication for years of hard work and sacrifice which no doubt secures the path to further education and future success. The fact that you are going to be awarded a grade from "somewhere" means that the next step in your life is probably not compromised in any way - you will be able to move on to college, 6th form, apprenticeships or elsewhere, but it is what you've lost in these coming months that can never be regained which saddens me the most - you are victims of a devastating world crisis that just happened to pass you by at the wrong time. There are wider implications here too - it is not unreasonable to suggest that the country will find itself winding down, locking down even further over the coming weeks. It would not be absurd to think in two weeks time we could find ourselves in an Italy/China/Spain situation where the streets are empty. You are at an absolutely golden time in your lives, especially from a social point of view. The time you spend with your friends and, dare I say it, even us as staff in school, makes a huge impression on all of you in your most formative of years. There is every chance that you will miss the chance to have those final goodbyes, the leaving speeches and assemblies and the prom nights. These are the moments you've earned, that you deserve that will no doubt become collateral damage in this situation. I would urge you all to find sensible alternatives! Year 11 and 13 are a time not only of looking to the future, but also of closure on part of your past - and what a time it has been. It wasn't supposed to be like this and we are clearly not going to be back in school this academic year - if exams have been cancelled then the government is clear - their models show there's no way we can get back together within a few weeks, it is going to be a period of months. I would like to take this opportunity to emphasise to all of my year 11 and 13 students what a genuine pleasure and privilege it has been to have the opportunity to guide you through two of the most important years you can have in your lives. In Year 11 I honestly felt like we were going to do something special this year, you were really about to pull it out of the bag when it mattered the most - every single one of you without exception. I'd like to thank you sincerely for your efforts and also for choosing my subject (and for being my self help group when I'm telling you stories about nothing at all). I hope to see many of you next year for A-Level. To Year 13 - you are genuinely one of the kindest, close knit groups of students I have ever known and it's actually a positive to know that your routes to higher education are now practically guaranteed - you deserve it, even if your coursework was horrendous in the main. I will still never get over the games where "you can kill the enemies" only everything is invisible and suddenly you die. You really did invent a new genre of gaming - frustration through absurdity. Let's finish on a positive note - you are out of school now to save lives. There cannot be any misunderstanding here, cut out the noise of the ill informed and those who are mad enough to actually still read and believe newspapers - the science is clear. Closing schools is part of a much wider effort to slow society down, we are trying to prevent vulnerable people from dying of a disease we will soon be able to cure with vaccines. You are sacrificing your time now so these people may have the time they deserve to spend with their families and friends without the fear of being in a life threatening condition in hospital. In my opinion, whilst I don't want schools to close, it is the right thing to do if it saves lives and stops the NHS from reaching saturation. We are living in a time when no one knows what to do. The top scientists and medical experts across the world are learning as they go along. The economy world wide is on its knees and people are living in abject fear - fear of the disease itself, fear for their children and families, fear of losing their jobs, livelihoods and income. All of these fears are very real. Fear makes us behave irrationally and do things that, from the outside, can appear stupid, odd or selfish. Be kind to each other - before you voice an opinion, ask yourself what underlies their behaviour, why are they doing the things they're doing? Make it your priority to stick together, to look out for each other and above all look out not only for your physical health but your mental health as well - stress is high right now and your parents, carers and loved ones may look ok on the outside but on the inside many may be terrified. Be mindful of that when you're raging about something insignificant and give people at home a chance to breathe, take stock and work out what to do next. We'll survive, but my friends the world is about to look very different to the one we knew only a few months ago. Stay safe, stay kind. More free posters! These are designed to give students a very visual overview of the following GCSE options:
See the post below for editing instructions - these are fully customisable Publisher files so feel free to change as you see fit for your options. Remember, you will need to download the "transport" font for these to display correctly, this is an open source font and so can be distributed freely. 
The content on this website is free for anyone to use and will always remain free simply because I fundamentally believe in the principles of comprehensive, free education. Sadly, however, it has come to light recently that a number of the resources available here (and also some older materials from our KS3 provision) have been uploaded, used and claimed by other individuals as their own. That's not ok. Why?
There is one key thing to note here - you can only do this if you attribute us/me/this site - in other words, acknowledge that these resources are not your own. You also cannot sell our resources or derivatives of my resources for profit. This goes against all of my principles. The reason for this is quality control. I take great pride in the standard of my work and I constantly review and update these resources as I find things I'm not happy with, as I learn from experience and as I simply think things need to be refreshed or changed. For exmaple, I'm practically re-writing unit 2 of the GCSE as we speak becuase I don't think it's good enough. You will be able to get these resources for free as usual. If you upload our resources, claim them as your own or share them as your own then the people you share with are getting a poor experience. They do not know the origin of your files, nor will they benefit from the constant improvements we make. To see comments on websites from teachers praising these lessons as "outstanding" actually makes me sad - they're not outstanding and that's why we've since moved on from delivering them in that form. Bottom line - please don't give your students a second rate experience, please don't steal resources and claim them as your own.

Just because something is given away for free does not give you ownership or copyright.  Being as careers appears to be high on the education agenda recently, I decided to put together a display which can be used in classrooms to highlight the pathways from Year 7 all the way into a select number of careers. It's not designed to be a super informative infographic, literally something which is useful to have, starts a conversartion and clearly shows the fact you have clear paths through school into technology based careers.  Here's one I made earlier... </Bluepeter> It's designed to be printed out at size A0 using a plotter and the file is available to download below. A few notes if you want to use it yourself:
To create new "signs" to add to your display, don't bother trying to grab an image or SVG and then adding text over the top, you'll never quite get what you're after. Instead use rounded rectangles and add text to them, then set the colours using the RGB colour codes available as linked above. Hopefully some of you will find this useful. If you don't have a plotter, you can go thoroughly old school and get publisher to print it out as a series of smaller pages that you can then tape together. I'd suggest laminating them first if you go down this route!
 What does AEG stand for? "Aggravation, Exasperation, Grief" perhaps? So, some three years ago I made the fatal error of buying something without having done my homework first. In this case, a very, very expensive washing machine made by AEG called the "Lavamat Turbo." For Google robots and anyone else who may be suffering the same fate and would like to read my tale of woe, the model number of this particular pile of junk is l61470wdbi. What's wrong with it, then? Well, it's a two pronged attack from this beast - not only is it terribly made from a reliability and construction quality point of view, but it's also incredibly poorly designed. Last night, it died for the third time. I'm not sure that one breakdown per year qualifies as decent quality in anyones book, but consdering how ancient I am and the fact I've never actually managed to break any other washing machine in my life, this must be some kind of indicator as to just how appalling this particular machine is. Oh, and I'm fully aware how old I sound recounting my illustrious, long history of washing machine ownership, but there's definitely a technology angle here so bear with me. The fault, then, was an interesting one. Turn the machine on, select a program, press go. The door clicks, all the lights look happy. As you would expect, I then walked away thinking nothing more about it - the days are long since gone that watching the washing machine cycle to completion was a form of family entertainment... Then it struck me how quiet everything was. Too quiet. I went back to find the timer happily counting down to itself but literally nothing happening at all. No movement, no water, no swishing of laundry. Eerie silence. What's wrong here is this - the machine was doing two things:
"Ah! But if it's faulty what can you expect?!" Being unable to believe anything is fixable only by a professional, I started poking around the internet for answers. It turns out that this machine has error codes. How useful! Yes, if only they actually appeared on the display. This is where, from a design and software engineering point of view, things get really stupid. I learned the magic incantation and performed finger acrobatics on the buttons to reveal the magic error - E41. What's wrong here?
 If you see this washing machine, run. Run like the wind! This is just plain stupid. It cannot even be argued that hiding the error code in some way helps prevent confusion or even protects customers from coming to some kind of harm - it's information! Nothing more. Why decide that some errors can be displayed and others are only for those who have sworn an oath and gone through the sacred order of the washing machine repair person, complete with complimentray rubber seal crown? Some of the errors it will show you are comedy - there's one called EFO which tells you the water is leaking everywhere. This is one of the errors they could've hidden. I know this becase when this very machine flooded my kitchen it was very, very obvious what had happened... It is these inexplicable design choices that make my brain boil. I keep going back to this point - Steve Jobs was a genius because he recognised the need for complete and utter design consistency. The need for items to behave in such a way that you never needed to ever encounter a machine behaving in a seemingly random or inexplicable way. Like it or not, this washing machine would never have made it to production if he'd been inclined to design kitchen appliances. When designing a system, choices are made. Somewhere, at some point, someone consciously made the decision that this machine would have a comprehensive set of diagnostic error codes to help the repair process. However, they also made the decision that this valuable information should be hidden and that the machine should just pretend nothing is wrong? So what's actually wrong? Well, E41 means that probably the door latch is in some way broken. Either that or the main control board has fried itself. This is one of those "worth a punt" situations because the door lock is £13 and for once I don't have to hump a machine that weighs more than an elephant out of a cupboard to try and fix it for once. The part has been ordered and we'll see what mess I get into when I fail to reseat the seal round the door properly. The machine that keeps on giving once decided to flood the kitchen. This is something that shouldn't really happen on a grand scale. Would you like to learn about washing machine electronics and control? Of course you would. I was surprised to learn that the way in which a machine judges the amount of water that is inside it and when to turn the tap off, is not by measuring the flow of water in to the machine - which just seemed to be the way to do it in my head. Instead, there is a small rubber hose inside that has a pressure sensor on one end. As the machine fills with water, the air pressure increases until the sensor reads a certain amount and the control board shuts off the supply. This is actually quite a reliable way of doing things until. that is, the rubber hose gets a hole in it. This "shouldn't" happen, but it was pub time in the AEG factory when my machine was built and they couldn't be bothered to attach it properly so the drum rubbed a hole in it. No problem - the machine has a feature to prevent this very problem! It's even part of their sales pitch, the machine is intelligent enough to cut itself out should it suffer any failure in the water department. The question is... why did my kitchen flood then? The answer is wonderful. Inside the bottom of the machine lies the answer to this "intelligent" function. It's a piece of polystyrene. When water escapes the machine the bottom of the machine floods, the polystyrene floats up which clicks a switch that tells the board to cut the water and turn the drain pump on. Brilliant. Such a simple solution! With only one minor problem.  "An excellent plan, sir! With only two minor flaws. One, we don't have any rocket pants and two, there is no such thing as rocket pants except for in the fictional cartoon strip 'Robbie Rocket Pants'" The problem is that the bottom of the machine isn't water tight, meaning a lot of water has to accumulate around it before the little float can do its job. Furthermore, the float has to raise about 1cm before it triggers the switch. Trust me, 1cm deep is a lot of water outside of the bath...
In a world where devices are becoming more and more "smart" and more connected for no reason other than "we can" (why I need a wifi washing machine I do not know) there is a desperate need for us to understand that simplicity is still the number one most important factor when designing anything electronic. The fact is we shouldn't forget that the very word "appliance" means something that should be plugged in, maybe have one button pressed and it just goes and does the job it was designed to do. A lot of the time we are trying to solve problems that sumply don't exist or create "convenience" that is verging on the absurd (smart lights anyone?) for the sake of selling kit, rather than actually adding value. The day my house gets smart lights and an internet connected fridge and washing machine is the day I buy a large set of wire cutters and go on a snipping spree to rid myself of the madness.
We need to understand a simple premise - nothing is free. There is always a price to pay, even for services that are free at the point of sign up or delivery.
Facebook, Whatsapp and Instagram are all free to use and all owned by Facebook/Mark Zuckerberg. If nothing truly is free, then we have a few questions to answer:
We've already discussed the moral angle to social networks, especially Facebook in previous posts, so in light of the annoucement that Mr Zuckerberg finally plans to do the inevitable and merge the three platforms, let's have a look at the privacy angle for a change. and examine the impact this merger will have on you as a user.
There is absolutely no way, in a million years, I would trust a word that came out of this mans mouth.
From a business point of view, Facebook's ownership of three platforms that perform similar or identical functions doesn't make a great deal of sense. Currently you have:
In business, developing, maintaining and hosting services which are similar or do the same thing isn't logical. You're spending too much, employing people to do the same or similar jobs and you're splitting up the data or information you've collected which is by far your biggest asset. Zuckerberg faithfully promised when WhatsApp was taken over that it would always remain a stand alone service, continuing to be seperate from Facebook. When they took over Instagram they promised the same. No one in their right mind believed him and... blow me down with a feather if he hasn't gone back on this promise and openly announced the merging of similar services. Of course, this is marketed as being in our best interests and to provide us with a smoother, more customised user experience.
It is not in your best interests.
It's quite funny to talk to students about their social media preferences. They'll be almost disgusted that you'd suggest they use Facebook these days but will openly and passionately advocate their use of Instagram. It's the same platform! Soon, it really will be the same platform. In software development, web development and hardware management terms it would be sheer madness if Facebook allowed these services to be separate for any longer than is strictly necessary. I will knit the hair of a dog into a fetching jumper if they haven't been working on this merger from the day the takeover was completed. The future is likely to be quite simple, they don't need three messenger services so they'll close them. This may be explicit in, for example, the removal of direct messages in Instagram and the closure of Facebook Messenger, or it could be far more subtle in that the apps themselves will continue to exist but the underlying code and messaging platform will be identical, only the "front end" will look different. But why should you care, why does this matter? The answer is simple. Absolutely everything that has happened since the inception of Facebook has proven one simple fact: You cannot, and should never, trust Mark Zuckerberg with your data and he has absolutely no respect for your privacy whatsoever. How can I make such a bold and sweeping statement? Simply, how can anyone respect your privacy when their entire business model is founded on the principle that they need as much of your data as they can possibly get their hands on in order to sell it to other businesses or advertisers. Furthermore, Zuckerberg and Facebook have been found out time and time and time again for:
The list is honestly endless. But, there's more. 
WhatsApp founders Brian Acton and Jan Koum. Both of whom left WhatsApp because of Zuckerberg and started the #deletefacebook movement. (Click the image to read more)
WhatsApp had a big selling feature - end to end encryption of your messages. Put simply, this means that no one but you and the recipient of your messages should be able to find out what you're talking about. If someone intercepts your traffic then they shouldn't be able to make sense of it. This has a huge business down side - you can't read your users content and trust me, they want to.
If this sounds odd, consider the fact that Google read your email if you have a Gmail account. They're very open about the fact that everything you upload to a Google service, such as your photos, emails and so forth will be used to train machine learning algorithms. Every now and again a real human will need to check that work - which is why you've heard "scandals" recently where Amazon, Apple and Google all had to "admit" they were employing hundreds to workers to listen to thousands upon thousands of recordings from smart speakers, obviously including those false positives when your speaker kicks in when you haven't asked it to. Someone, somewhere listens to you telling your speaker to go away... People are so used to this invasion of their privacy in return for something free such as an email account or a decent search facility that they either don't notice, don't care or simply its passed them by that this even happens. We've all noticed the "spooky coincidence" that you mention you fancy getting a talking pet frog and then suddenly, all your adverts on social media suddenly turn into pet frog websites. This isn't coincidence and only happens because our privacy has been invaded and eroded to an already unacceptable level. How does this happen? Profiling and information sharing. You don't need to do anything, log in to anything or do anything out of the ordinary to enable algorithms to work out who you are, what you're doing, what you like and most importantly - to connect your behaviour on different apps, platforms and networks together to effectively follow you around. Data mining and gathering is so good now that an algorithm can work out that you're you regardless of whether you use different devices, different user names or even move around the country. Think about when you spend time with your friends and YouTube suddenly recommends similar things to you - this is based on your location data, data which is so powerful it even tells these companies what job you do, your daily schedule, your shopping habits, who you hang around with, what you do when you're with friends even down to which apps you're all using when you're busy ignoring each other. The bottom line is this - you don't even have to be using an app these days for it to learn all about you and the amount it can learn about it is eye watering. But Mr Zuckerberg isn't happy with this. He wants, and has your permission to access, more. Zuckerberg wants to be able to tell advertisers as much as is possible about you, what you like, what you do and what you talk about (and to whom). This is where he fell out with the founders of WhatsApp, two people who posessed something crazy and disagreeable to Zuckerberg - Morals. Facebook want to take data from your messaging habits and use this to profile you further. It makes their advertising platform even more profitable and attractive. Both founders of WhatsApp left citing Zuckerberg's complete disregard for the privacy of users and their data, he is literally hell bent on monetising you and your information whether you give him permission to or not. This is illustrated by the fact that Facebook Messenger is indeed capable of end to end encryption but its disabled by default and buried in the settings where they hope you don't find it. When this merger of platforms is complete, you can guarantee that your behaviour in WhatsApp will be used to target advertisements to you. You can guarantee that your conversations or use of the app is nowhere near as private as you think it is. In short, you've got to be stark raving bonkers to use these platforms any more. So what can you do? The answer is simple. Delete Facebook, delete WhatsApp and be careful what you post on Instagram and certainly don't use it for chat. The alternatives are obvious - the guys who founded WhatsApp went and created Signal. It's the exact same thing as WhatsApp, has the same functionality and has the added bonus that they're not out to make money from your conversations. Just stop and think for a minute - would you want anyone, ever, seeing your messages? I'm not saying Zuckerberg is going to decrypt your conversations, but there is every chance they will be trying to find every possible way to gather data about what you discuss, how, when, where and with whom. This will then be used to link you to behaviour on other platforms. No thanks, not for me. If you have any sense, you will use Signal or another messaging app and you will get the hell away from anything owned by Facebook. And we haven't even started on their crypto currency, but that's a story for another time... To tidy things up and simplify the content and design of this site, we've split off the OCR GCSE Business content on to another site. This meant careful consideration had to be given to the name of the new site, it had to be:
www.sharetheinterest.co.uk OH YEAH! See what we did there? Share? Interest? Business terms and.... double meaning! It's like learn it with davo 2.  WOOF! BOOM!
I have no shame. See you there... You may or may not have noticed the new "GCSE OCR Business" link appaear in the menu at the top of the page. Today I've uploaded the first module of lessons for our students and any other schools to use as they see fit. Hopefully they'll be of some use to you!
Currently, we've only got 1.1 - Business Activity uploaded, the remaning parts of Unit 1 will be uploaded as they are completed. As usual, if you are a student and you miss a lesson/want to revise a topic then they're a great place to start/catch up...! Revision resources are planned for the future, most likely in the form of video tutorials. Keep an eye out for updates in the near future! This year is all about refinement and updating of our resources and the first part of that process has been to change some of the lessons we've been delivering. If you look on the GCSE CS - Lessons page now, the Unit 1 - 1.1 lessons have significantly changed to make them more digestable, to focus more on the important learning points and to, quite frankly, make it a little bit more interesting.
If you do use these resources then keep your eye out for changes as I'll upload new copies of lessons as and when they are updated. One other target for this year is to update the Unit 1 revision resources to include more video content, just to add another type of resource for revision or lesson purposes. I'll provide an update here when this happens later in the year. |
