If you're setting up a worksheet only for yourself, you can simply leave an empty cell for this purpose. To check it, just type in an x or any other character. Then use a formula with the =isblank() function to make the contents of that cell affect the rest of the spreadsheet. But you might want something more mouse-friendly--especially if you're designing a spreadsheet for other people. I've tested the technique below on Excel 2007, 2010, and 2013. I'm not sure about earlier versions. You can insert checkboxes on Excel's Developer tab. Unfortunately, that tab is hidden by default. To make it visible in Excel 2010 or 2013, click the File tab and select Options. ClickCustomize Ribbon. You'll see two lists. Make sure that the one on the right is titled Main Tabs. Check Developer.

"If you're not familiar with the Ignite format you create 20 slides, and have exactly 15 seconds per slide to share your story. It's a five minute pressure cooker because if you get off on one slide it can mess you up for the rest of your presentation. Or not... :-) Unfortunately I don't think my ignite session was recorded but I will try to share it here. I will include the script I had written, but any one who was there will know that in the end I completely ignored my script. I'm hoping this script was close enough to what I shared on Wednesday night."

"Today there are many resources for people to learn code. The Barbies and GI Joes of yesteryear have become tablets and smart phones. Young kids, such as 12-year-old Thomas Suarez, who gave this excellent TED Talk, are learning advanced forms of coding that few adults even fully grasp. The following is a list of websites online that offer free tutorials and courses for children that want to learn how to code. And even if you are not a kid, you might learn a thing or two. We reviewed a collection of websites and the following three are the best that we found, incorporating various features that put them above the rest. We went through all the most popular coding websites on the Internet and found the three best free coding websites, based on the following criteria: ● Ease of use ● Aesthetics ● Fun ● Effectiveness ● Free Without further ado, the following are the best coding websites we found that was designed especially with kids in mind."

"According to a study conducted in the chemistry department of the Catholic University done by Diane M. Bunce, Elizabeth A. Flens, and Kelly Y. Neiles in Washington D.C., it was found that while the original belief of the 10-15 minute attention span may be true, it was not the whole truth. Here is the rest of the story. It is true that the first lapse of attention (or first break in attention) occurred at approximately the 10-18 minute mark, but after this initial break, the later attention lapses occurred more and more frequently. By the end of class, attention breaks were cycling every 3-4 minutes. In other words, in the last parts of class, students are only paying attention for 3-4 minutes at a time! So what does this mean for you? This means that introducing different elements into the routine may benefit both you and your students by helping them pay more attention so that you can be a more effective teacher. This is where the pomodoro method comes in."

"There are lots of great learning opportunities when you use green screen effects in the classroom. I've written about some of those before, but almost all of them involved green screen movies. What about green screen photography? Is that possible on an iPad? It is, because there's an app for that. Recently I was reminded of the ability to do green screen photography when I read a blog post by Dr. Wesley Fryer. He did a green screen photo booth at the Fall Festival of the school he works at in Oklahoma. Great idea. So how do you do it? It all starts with the Green Screen app by DoInk. The rest is easy! Here's how it works."

"Finland's education system, often held up as an exemplary model for the rest of the world, is on the verge of making some major changes. For years, Finland has led the pack in international test scores, becoming a source of fascination for education policymakers and experts. Now, the country is changing the way it teaches students. Going forward, Finnish schools will be placing less emphasis on individual subjects like math and history, and will instead focus on broader, more interdisciplinary topics. The goal, according to Finnish leaders, is to provide students with the necessary skills for a more technological, global society. Here are three things you need to know about Finland's changing education system:"

"ACCORDING TO AYAH Bdeir, technology is the language of our time. The 33-year-old founder and CEO of littleBits likes to compare the engineers of today to the clergy of the Middle Ages, who controlled access to knowledge and power via their monopoly over the use and understanding of the written word. Today's engineers have a special kind of social and technological influence, which derives from their understanding of the stuff that makes our everyday gadgets work. If our lives today depend on technology, then those who truly understand it have an outsized influence over the rest of us. In Bdeir's view, littleBits-a range of Lego-like electronic circuits that can be used by virtually anyone to innovate their own gadgets-isn't just a plaything, it's an aid to achieving widespread tech literacy. You might even think of littleBits as a democratizing project. "You see these kids growing up with laptops and smartphones, and by the time they're toddlers, they already seem so tech savvy," Bdeir notes. "But they don't actually understand how the technology works. They're great at navigating around a touchscreen, but if they only ever know that much, they'll wind up relying on other people-these specialists who studied engineering in school-to decide what kind of technology they have access to.""

"Composing a story from scratch comes naturally to some people. For the rest of us creating a story from scratch can be a struggle. Over the years I've found that using pictures helps a lot of students get started on crafting stories. In some cases I've had students create collages to represent elements of a story. In other cases I've had them choose five pictures and write two hundred words about each. Being asked to write two hundred words about five pictures feels a lot less daunting than being asked to write one thousand words in one shot. The PDF embedded below (click here if you can't see the embedded document) outlines how to use ten of my favorite free tools to create image-based stories. "

"The question is, to prevent this deterioration in scores and perceived ability, how do we empower elementary school girls to embrace an interest in STEM and develop leadership skills that will help them navigate their way through school to be prepared to choose any career, including STEM? How can educators address the main factors at this critical 9- to 12-year-old window that are standing in the way of more girls going into STEM fields?"

"The single most important skill you will ever learn is in itself an oxymoron. It is dependent on your ability to vanquish procrastination and achieve something today with view to tackling the unknown that comes tomorrow. As I've written previously it requires the drive to tackle the modern world head on: doing nothing has never been so easy. Got a spare few hours? They can disappear as quickly as unlocking your smart phone. For me then this affords opportunity for those who have taught themselves the skill I allude to; to learn how to learn and have the desire to maniacally do so for the rest of your life. The ability to employ autodidacticism in your every day life is the single most valuable skill you can ever acquire and employ. Self-directed learning enables you to learn the skills that you are most passionate about and employ them in innovative way to achieve your goals and ambitions. We no longer need schools, universities or teachers to spoon feed us the information you are paying to acquire. Go out and try finding what interests you and expand your horizons through learning. Schools are broken, they teach you memory skills required to pass exams at the detriment of teaching you what it means to learn."

"The choices we make during the first hour or so of our morning often determine what the rest of the day will look like. Will your morning routine grant you a day full of productivity and peace of mind? Or will you be looking at an eight-hour stretch of haphazard work? Over the past five years I've interviewed more than 300 successful people about their morning routines. Through talking with business leaders and university presidents to Olympians, fashion models and artists, I've learned that while there isn't one "best" morning routine that works for everyone, there are best practices that some of the most successful people I spoke with follow every day. Here are some of the most common morning routines I've found among successful people."

As is required of all women in their 30s, I am in a book club. At the first meeting of this group, one poor unsuspecting woman mentioned that she had listened to that month's selection instead of reading it. That, the rest of the group decided together, is definitely cheating. Never mind that no one could exactly articulate how or why it was cheating; it just felt like it was, and others would agree. She never substituted the audiobook for the print version again (or, if she did, she never again admitted it). This question - whether or not listening to an audiobook is "cheating" - is one University of Virginia psychologist Daniel Willingham gets fairly often, especially ever since he published a book, in 2015, on the science of reading. (That one was about teaching children to read; he's got another book out next spring about adults and reading.) He is very tired of this question, and so, recently, he wrote a blog post addressing it. (His opening line: "I've been asked this question a lot and I hate it.") If, he argues, you take the question from the perspective of cognitive psychology - that is, the mental processes involved - there is no real difference between listening to a book and reading it. So, according to that understanding of the question: No, audiobooks are not cheating.

"In a perfect world, all of our students would come to school every day well rested, well fed, clean, healthy, happy, feeling good about themselves and ready to learn. But some of the time, and perhaps for a significant segment of our students, that is not the reality. So yes, schools need to be clear on their priorities and make tough choices in supporting students while making sure their basic and psychological needs are met before we can aspire to assist them with their self-fulfillment needs. It's a delicate dance schools must do in supporting students with their varying needs; a balancing act of sorts that comes with great consequence. What complicates this even further is the reality of the very dynamic, digital world our students are growing up in. With a shifting world, comes shifting needs. And along with shifting needs comes a shifting role that schools must take on in order to best prepare students moving forward. We must revisit the graphic above to explore and best support students with their changing needs in our DIGITAL WORLD. In some cases, students get these emerging needs related to our shifting world met at home, but for others, this is not the case for a variety of reasons."

"Mastering digital communication is much more than just about being safe and courteous online. It's also part of being a great Global Digital Citizen-the kind of citizen we must begin cultivating in our schools. digital At the Global Digital Citizen Foundation, we believe the role of an effective digital communicator is to show courtesy, integrity, and respectability in all forms of technology-based interactions and associations. Moreover, their role is also to model this behaviour for the rest of us. It makes sense to cultivate our learners to become such empowered individuals that are aware of their responsibility both for and with the power of the Internet, for the lasting well-being of our global community. Moving forward, then, how can we help them realize the meaning of a truly exemplary digital communication? What does such a practice look like in action?"

"Just glance at your inbox and odds are you'll find at least one variety of phishing scam or email hack. Whether it's spear phishing, spoofing, account takeovers through embedded malware, or that time-honored plea from a Nigerian prince, there's no doubt that our schools' email systems are under near-constant attack. One careless click of a link can turn a teacher's account into a spam factory, landing your email system on a blacklist and cutting off communication with the rest of the world. Providing employee tax information to a phisher posing as your superintendent, for example, can result in the identity theft of hundreds of employees. The sad truth is that phishing and spamming scams are now part of life in this digital age. But through more engaging education, more authentic practice, and more creative protection practices, schools have a much better chance of mitigating the impact."

"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"

"Problem-solving skills are necessary in all areas of life, and classroom problem solving activities can be a great way to get students prepped and ready to solve real problems in real life scenarios. Whether in school, work or in their social relationships, the ability to critically analyze a problem, map out all its elements and then prepare a workable solution is one of the most valuable skills one can acquire in life. Educating your students about problem solving skills from an early age in school can be facilitated through classroom problem solving activities. Such endeavors encourage cognitive as well as social development, and can equip students with the tools they'll need to address and solve problems throughout the rest of their lives. Here are five classroom problem solving activities your students are sure to benefit from as well as enjoy doing:"

"What is a morning ritual? A morning ritual is a series of habits, acts, or practices, usually completed in the same order, day after day. And these rituals are vitally important--the way we begin our morning sets the tone for the rest of our day. A calm, relaxed, and nourishing morning ritual empowers you to deal with the inevitable challenges you'll encounter, reduces stress, increases productivity, and helps you live more intentionally. And getting out of bed is a lot easier when you have something to look forward to! Developing a morning ritual is a very personal thing, and one that evolves over time to be responsive to your needs. This blog post is a window into my current morning ritual that will hopefully inspire you to develop your own."

"There's no shortage of great websites, apps and programs available on the Internet. Some, however, rise above the rest. Your 2014 list of our 11 most useful tools of 2014 covers everything from creating charts to making your computer screen a little easier on the eyes. Of course there's plenty we missed, but these are some of the tools that came to our attention this year."
