"The groundwork for machine learning was laid down in the middle of last century. But increasingly powerful computers - harnessed to algorithms refined over the past decade - are driving an explosion of applications in everything from medical physics to materials, as Marric Stephens discovers When your bank calls to ask about a suspiciously large purchase made on your credit card at a strange time, it's unlikely that a kindly member of staff has personally been combing through your account. Instead, it's more likely that a machine has learned what sort of behaviours to associate with criminal activity - and that it's spotted something unexpected on your statement. Silently and efficiently, the bank's computer has been using algorithms to watch over your account for signs of theft. Monitoring credit cards in this way is an example of "machine learning" - the process by which a computer system, trained on a given set of examples, develops the ability to perform a task flexibly and autonomously. As a subset of the more general field of artificial intelligence (AI), machine-learning techniques can be applied wherever there are large and complex data sets that can be mined for associations between inputs and outputs. In the case of your bank, the algorithm will have analysed a vast pool of both legitimate and illegitimate transactions to produce an output ("suspected fraud") from a given input ("high-value order placed at 3 a.m."). But machine learning isn't just used in finance. It's being applied in many other fields too, from healthcare and transport to the criminal-justice system. Indeed, Ge Wang - a biomedical engineer from the Rensselaer Polytechnic Institute in the US who is one of those pioneering its use in medical imaging - believes that when it comes to machine learning, we're on the cusp of a revolution."

"Before computers can be used to solve a problem, the problem itself and the ways in which it could be resolved must be understood. Computational thinking techniques help with these tasks."

"Every year since 2001 we've picked what we call the 10 Breakthrough Technologies. People often ask, what exactly do you mean by "breakthrough"? It's a reasonable question-some of our picks haven't yet reached widespread use, while others may be on the cusp of becoming commercially available. What we're really looking for is a technology, or perhaps even a collection of technologies, that will have a profound effect on our lives. For this year, a new technique in artificial intelligence called GANs is giving machines imagination; artificial embryos, despite some thorny ethical constraints, are redefining how life can be created and are opening a research window into the early moments of a human life; and a pilot plant in the heart of Texas's petrochemical industry is attempting to create completely clean power from natural gas-probably a major energy source for the foreseeable future. These and the rest of our list will be worth keeping an eye on. -The Editors"

"School teachers need to better prepare pupils of the risks posed by "fake news" and disinformation online, the education secretary Damian Hinds has warned. Every child will learn about confirmation bias and online risks as a compulsory part of the curriculum as the government publishes new safety guidance for schools. Teachers will have to help children learn to evaluate what they see online, how to recognise techniques used for persuasion, how to identify potential risks and how and when to seek support. "

"The spread of online misinformation poses serious challenges to societies worldwide. In a novel attempt to address this issue, we designed a psychological intervention in the form of an online browser game. In the game, players take on the role of a fake news producer and learn to master six documented techniques commonly used in the production of misinformation: polarisation, invoking emotions, spreading conspiracy theories, trolling people online, deflecting blame, and impersonating fake accounts. The game draws on an inoculation metaphor, where preemptively exposing, warning, and familiarising people with the strategies used in the production of fake news helps confer cognitive immunity when exposed to real misinformation. We conducted a large-scale evaluation of the game with N = 15,000 participants in a pre-post gameplay design. We provide initial evidence that people's ability to spot and resist misinformation improves after gameplay, irrespective of education, age, political ideology, and cognitive style."

"Although it's difficult to change the way the (school) system operates, it is possible to adjust how you operate within the system. Introducing meditation and mindfulness techniques in the classroom not only allows you to create a calmer environment, the practice has proven to have verifiable benefits on the human brain. A 2011 Harvard study of MRI images showed a thickening in the cerebral cortex (an area responsible in part for attention and emotional integration) in meditation participants in as little as 8 weeks. So, it's more than a good habit and some quiet time in the classroom, you may be helping the brains of your students develop even more than you realize. Where do you even begin teaching meditation when you may not be familiar with the practice yourself? Although it seems like an incongruous match, this is yet another area where technology steps in to make learning convenient, and a variety of apps offer options for every age, ability, and amount of available time. Here are a few to experiment with as you get started."

"Architectural Design is not a subject normally taught in schools. Because it presents something of a novelty to children, it often produces some very creative and exciting results. Furzedown Primary School in South West London regularly hold a sequence of lessons in its summer term focusing on this with a Year 5 class. The process starts looking at structure and continues with spacial design, materials, drawing techniques followed by model making. The children are normally given a brief and asked to design a pavilion. To conclude the sequence of lessons, a selection of projects is chosen to build full scale."

"With so many classroom research studies published daily, you can be forgiven for missing some. The techniques below are super-tactical and, for the most part, unsung strategies that you'll be excited to try tomorrow."

"Health education is one of the most important parts of schooling, but current techniques and curriculum tend to be a bit outdated - old books and even older information is being reiterated over and over, teaching the next generation dated science about how the body works. Even when the info was current, these old teaching methods go in one ear and out the other for many in this generation - they're immersed in technology from a very young age, often before they're old enough to speak or walk. Health apps are the best high-tech way to teach kids about their bodies and how to keep them in shape. What are the best health apps for teaching K-12 students about health?"

"A successful engineer constantly searches for new information and techniques to employ more efficient and economic designs. Keeping up with the times used to require constant schooling and endless hours spent at university libraries searching through countless papers. Today, through the rise of the internet, the information to improve methods and technologies has never been so accessible. Now, maintaining a sharp, creative mind requires nothing more than clicking away through the endless archives on the internet. Listed below are the most useful engineering websites that every engineer should have at their disposal - both in and out of school.

"Much like cooking, computational thinking begins with a feat of imagination, the ability to envision how digitized information-ticket sales, customer addresses, the temperature in your fridge, the sequence of events to start a car engine, anything that can be sorted, counted, or tracked-could be combined and changed into something new by applying various computational techniques. From there, it's all about "decomposing" big tasks into a logical series of smaller steps, just like a recipe."

"Before computers can be used to solve a problem, the problem itself and the ways in which it could be resolved must be understood. Computational thinking techniques help with these tasks."

"Learning how to solder w/ proper soldering techniques is a fundamental skill every maker should master.  In this tutorial, we outline the basics of soldering irons, soldering stations, types of solder, desoldering and safety tips.  Whether you're building a robot or working with Arduino, knowing how to solder will come in handy."

"Anyone who says you can't apply computational thinking and digital learning strategies to strengthen students' writing skills is wrong. To the contrary, this innovative learning style helps students hone critical-thinking skills across every discipline. In my classroom, I teach students computational thinking through free materials from Ignite My Future in School, a partnership between Tata Consultancy Services and Discovery Education. I especially enjoy using their Curriculum Connectors, online resources for teachers across disciplines to help their students apply computational thinking techniques. The core tenets of computational thinking are the building blocks that help my students become better learners and problem-solvers across every area of their work-from all areas of reading and language arts. Here's how five core computational thinking approaches help my students build stronger critical thinking and writing skills:"

"Regardless of whether you think every infant needs an iPad, I think we can all agree that technology has changed education for the better. Today's learners now enjoy easier, more efficient access to information; opportunities for extended and mobile learning; the ability to give and receive immediate feedback; and greater motivation to learn and engage. We now have programs and platforms that can transform learners into globally active citizens, opening up countless avenues for communication and impact. Thousands of educational apps have been designed to enhance interest and participation. Course management systems and learning analytics have streamlined the education process and allowed for quality online delivery. But if we had to pick the top ten, most influential ways technology has transformed education, what would the list look like? The following things have been identified by educational researchers and teachers alike as the most powerful uses of technology for learning. Take a look. 1. Critical Thinking In Meaningful Learning With Technology, David H. Jonassen and his co-authors argue that students do not learn from teachers or from technologies. Rather, students learn from thinking-thinking about what they are doing or what they did, thinking about what they believe, thinking about what others have done and believe, thinking about the thinking processes they use-just thinking and reasoning. Thinking mediates learning. Learning results from thinking. So what kinds of thinking are fostered when learning with technologies? Analogical If you distill cognitive psychology into a single principle, it would be to use analogies to convey and understand new ideas. That is, understanding a new idea is best accomplished by comparing and contrasting it to an idea that is already understood. In an analogy, the properties or attributes of one idea (the analogue) are mapped or transferred to another (the source or target). Single analogies are also known as sy

""Nothing could be more absurd than an experiment in which computers are placed in a classroom where nothing else is changed." - Seymour Papert When it comes to improving outcomes in the digital age, efficacy matters more than ever.  Billions of dollars are spent across the world on technology with the hopes that it will lead to better results.  Tom Murray and I shared this thought in Learning Transformed: Educational technology is not a silver bullet. Yet year after year, districts purchase large quantities of devices, deploy them on a large scale, and are left hoping the technology will have an impact. Quite often, they're left wondering why there was no change in student engagement or achievement after large financial investments in devices. Today's devices are powerful tools. At the cost of only a few hundred dollars, it's almost possible to get more technological capacity than was required to put people on the moon. Nevertheless, the devices in tomorrow's schools will be even more robust. With that in mind, it's important to understand that the technology our students are currently using in their classrooms is the worst technology they will ever use moving forward. As the technology continues to evolve, the conversation must remain focused on learning and pedagogy-not on devices. Unfortunately, technology is not a magic wand that will automatically empower learners to think critically, solve complex problems, or close achievement gaps.  These outcomes rely on taking a critical lens to pedagogical techniques to ensure that they evolve so that technology can begin to support and ultimately enhance instruction.  If the former (pedagogy) isn't solid, then all the technology in the world won't make a difference.  As William Horton states, "Unless you get the instructional design right, technology can only increase the speed and certainty of failure.""

"This time of year I get a lot of requests for resources to help students keep up their school skills over the long summer months. I searched the web for the best resources, tips, and techniques I could find. I focused on free resources to help keep it, well … free :). These resources cover a range of academic subjects and skills."
