"For too long, the American education system failed too many kids, including far too many poor kids and kids of color, without enough public notice or accountability. To combat this, leaders of all political persuasions championed the use of testing to measure progress and drive better results. Measurement has become so common that in school districts from coast to coast you can now find calendars marked "Data Days," when teachers are expected to spend time not on teaching, but on analyzing data like end-of-year and mid-year exams, interim assessments, science and social studies and teacher-created and computer-adaptive tests, surveys, attendance and behavior notes. It's been this way for more than 30 years, and it's time to try a different approach. The big numbers are necessary, but the more they proliferate, the less value they add. Data-based answers lead to further data-based questions, testing, and analysis; and the psychology of leaders and policymakers means that the hunt for data gets in the way of actual learning. The drive for data responded to a real problem in education, but bad thinking about testing and data use has made the data cure worse than the disease."

Modern data science emerged in tech, from optimizing Google search rankings and LinkedIn recommendations to influencing the headlines Buzzfeed editors run. But it's poised to transform all sectors, from retail, telecommunications, and agriculture to health, trucking, and the penal system. Yet the terms "data science" and "data scientist" aren't always easily understood, and are used to describe a wide range of data-related work. What, exactly, is it that data scientists do? As the host of the DataCamp podcast DataFramed, I have had the pleasure of speaking with over 30 data scientists across a wide array of industries and academic disciplines. Among other things, I've asked them about what their jobs entail.

"It took just one relentless bout of the flu to remind me of the power of empirical evidence and the importance of shooting data. More than numbers, it was the evidence gleaned from my experiences and the images that I gathered along the way that helped my doctor solve the riddle that was delaying my recovery. My kids thought I was crazy, but I took some photos to save the evidence, and my doctor appreciated this. Gross? Absolutely. Helpful? Definitely! The doctor said that the pictures inspired him to take a different approach in my treatment. "Good data gathering," he joked, and I smiled, recalling one of my greatest pet peeves: educators and parents who rant about their disdain for this very important work. To listen to some, you'd think data are only numbers that shady reformers crunch in order to cash in on imaginary problems created by incompetent teachers. This is a dangerous assumption. The fact is that data are information that matter, and if they don't matter or if the conclusions we reach aren't helping us solve important problems, then we need to change the data we're collecting and the way we approach analysis. After all, isn't it a bit silly to blame data for our own faulty decision making?"

"There ought to be a law limiting people to one use of the term "life-changing" to describe a life event. Had a life-changing cup of coffee this morning? Well, hope it was good because that's the one use you get! If this legislation came to pass, then I would use my allotment on my decision to write about data science. This writing has led directly to 2 data science jobs, altered my career plans, moved me across the country, and ultimately made me more satisfied than when I was a miserable mechanical engineering university student. In 2018, I made a commitment to write on data science and published at least one article per week for a total of 98 posts. It was a year of change for me: a college graduation, 4 jobs, 5 different cities, but the one constant was data science writing. As a culture, we are obsessed by streaks and convinced those who complete them must have gained profound knowledge. Unlike other infatuations, this one may make sense: to do something consistently for an extended period of time, whether that is coding, writing, or staying married, requires impressive commitment. Doing a new thing is easy because our brains crave novelty, but doing the same task over and over once the newness has worn off requires a different level of devotion. Now, to continue the grand tradition of streak completers writing about the wisdom they gained, I'll describe the lessons learned in "The Year of Data Science Writing.""

"It's all about perspective.  Too often when we hear the word "data" we assume that the person speaking is talking solely about summative test results and the plethora of possibilities for learning we can take away from those numbers.  But this is NOT the only kind of data that exists, it is just the kind that gets the brunt of our ire and frustration as it is a solitary indicator of teaching and learning. And that's what I struggle with. Test data is one single area for determining what kids know and can do and there are often many challenges with these standardized tests that skew the data on top of that. However, most classroom teachers and leaders are gathering data like masterful musicians in their classrooms every day and just don't realize that is what they are doing."

"Menomonee Falls - Once every few weeks this past school year, kindergarten teacher Tiffany Fadin corralled her squirmy young charges at Valley View Elementary to get feedback about their recent math lessons. "What specific things did we do in this unit that helped you learn?" she asked recently. "What things did not help you learn?" Behind Fadin, data points flashed on a board, showing how many more students could add and subtract within five digits than in weeks prior. The exercise was deliberate, underscoring a major shift in Menomonee Falls that's training everyone to use data to make decisions, from teachers and custodians to kindergartners. The strategies employed over the past four years have attracted national - even international - attention to Menomonee Falls, including visitors from Sweden and researchers from the Carnegie Foundation. Other districts around the state and other educational institutions, such as the State University of New York, are taking notes. Armed with promising new outcome data, Menomonee Falls Superintendent Pat Greco said she believes what they're doing is working, and that the district is the case study for how K-12 systems can increase achievement and efficiency. And they're doing it by employing methods rooted not in education, but in the manufacturing and health care industries. "Teachers were reticent about posting student performance data. They were reticent to invite feedback from students," said Greco, who began engaging a small core of staff in the work in 2011. "Now, student performance is the highest it's ever been," Greco said."

"These days, the world is at your fingertips wherever you are. Anyone with a data connection and a smartphone has literally the entire Internet in his/her pocket. However, not all apps are created equally, in terms of the amount of data that they use in order to run. This is a quick tip on how to save your data usage (and potentially quite a bit of money). The following will be especially helpful if you do not have a large data plan (more than 1Gb per month)."

"If you think data-in education, or any field-is cut and dry, think again. Working with data in the classroom, especially, can be either exhausting or exhilarating-depending on your fitness level. Data can be big, but also quite small. It's often quantitative, but is increasingly qualitative. It's predictive, but not always inclusive. It's private, but not always protected. But one thing's for certain: data has enormous power to impact teaching and learning."

Data occupies a somewhat curious place within education. Mention it to teachers and you tend to get one of two responses. One group will roll their eyes and with great sarcasm how data is "so exciting". The other group responds with something akin to "actually I quite like data" indicating that experience has shown them that they are members of a small group. The question is why do some people find data to be a useful and fascinating tool while others see it as a good method for inducing sleep? 

"I was listening to Chris Molanphy's excellent Hit Parade podcast this week, which is based on his equally great Hit Parade column for Slate Magazine. In this episode, he details the circumstances that lead the Beatles to hold the still-unbeaten record of having the top 5 spots on the Billboard charts all at once. More remarkably, it's not that this feat was achieved through their own talent - it was almost entirely a snafu caused by the lack of interest in the Beatles by major labels. Indeed, much of the feedback they had received from labels and the American music industry was tepid at best and negative at worst. Dick Rowe at Decca Records cemented his place in history by declining to sign the Beatles, saying "Guitar groups are on the way out." He wasn't wrong - the data he had showed that there wasn't likely to be much of a return in signing the Beatles. Instead, Decca signed Brian Poole and the Tremeloes, who would cost them less money. And so, you're probably wondering how in the world this connects to education. When I look at this moment in history, I see a lot of talented people making choices which are informed by data. As teachers, we too need to look at data. It's how we understand our students better, and when used properly, can be influential in shaping our practice to make our teaching more effective. Certainly data is used as a summative tool, but it is most useful as a formative tool for students and teachers alike. How does the use of data in regards to the Beatles relate to teachers?"

"One of the tasks I have in my to-do list for this month is to write a post on the difference between the digital behaviour of Generation Y and that of Baby Boomers. However today as I was sifting through my Feedly feeds I came across this interesting infographic entitled " Data Footprint by Generations ". Going through its content I found that it, partly, clicks in with the post I am working on. The graphic provides data about technology usage by the different generations. It particulalry tracks the digital footprint of these 3 generations in terms of their video viewing habits, Internet usage , and connected devices. I think it would have been way better if the designers of this infographic provided some more clarifications on the definitional elements of these 3 generations and not just limit the data on them to age-range."

"For years, it has been no secret that many students who start post-secondary education programs drop out early. To address this issue, many schools and institutions decide to redesign their courses with the hope that students might gain a greater feeling of success, continue with their chosen program and graduate. When considering courses for redesign, many questions are asked but the most important is this: "What data should be considered to ensure our course redesign efforts are successful?" Data metrics like grades, attendance or participation rates are obvious considerations. These can be reliable metrics in driving decision-making. However, I recommend also considering student feedback, faculty load, student experience, and assessment performance as additional data points which can better inform decisions that directly impact the course redesign process."

It is really very frustrating when you lose data due to hard disk crash or any other computer problem. Whether it is family photos, music collection or any financial data, keeping it safe is your responsibility. Thus, regularly backing up your data and settings is highly recommended.

"According to a recent Forbes article, data storytelling, which involves weaving data and visualizations into a compelling narrative, has become a sought-after skill in the job market. Today's variety of online tools and resources offer an opportunity to prepare our students to interpret their research in new and creative ways and to effectively communicate data-driven insights."

"Data is on overdrive. It's being generated at break-neck pace, flooding out of the dozens of connected devices we use every day, and it shows no signs of slowing down. In fact, the number of internet users has grown over a billion in the last five years, more than half of the world's web traffic now comes from mobile phones. In its fifth year, Data Never Sleeps shows exactly how much data is created every single minute. From tweets to swipes, likes to shares, the digital world is exploding. Have a look."

" Apple has long touted its device's assistive technology as a powerful tool for the educational development of physically and mentally disabled children. The iPad's touch screen makes it easier to manipulate than more traditional educational tools. For children with autism, "the iPad is not a toy, but a tool that works best when there is a 'team effort' between parents and therapists encouraging its proper use," said Marc Reisner, co-founder of Reach for the APPs. "Our goal is to provide schools with iPads so they can reach every child on the autistic spectrum." Reach for the APPs built their site with an initial donation from Managed Digital. Now, they're seeking out donations of money and/or iPads from both individuals and corporations to propel the program forward. According to reports from the Center for Disease Control and Prevention, 1-in-88 children have some form of autism, up 78 percent from just a decade ago. The demand for augmentative communications devices is growing. But the schools can't meet the demand, so the children are losing valuable time during critical developmental years. Lois Brady, a speech language pathologist and assistive technology specialist, said apps can help develop fine-motor skills, which will in turn make functions like writing and manipulating small objects easier for the students. "I have spent years working with the most challenging students that are considered profoundly disabled," she said. "And I have seen some small miracles when I introduce the iPad into our therapy, as the children have made huge gains in attention, focus, communication, language and literacy skills." Some experts also say that the iPad can lessen symptoms of autistic disorders, helping children deal with life's sensory overload. Brady will be contributing content to the Reach for the APPs website to inform therapists about the latest-and-greatest apps for children all over the autistim spectrum. Apps must be tailor

"ArkGIS is a customizable map developed by the World Wildlife Fund for the purpose of visualizing historical data about sea ice, marine life, and oil and gas exploration in the Arctic. To create custom visualizations of data layers on the ArkGIS map simply select a data category then select data layers to display. For example, I chose the "marine mammals" category then selected the "beluga whales" and "walrus" to view their distributions."

"One of the great advantages of the internet is the convenience of cloud based services where you can store documents, pictures, bookmarks or notes and access them on any device with an internet connection. Despite this level of convenience it is still important to maintain backups of your data in the case of unforeseen circumstances, such as your account being hacked or a service shutting down. Here we will take a look at a few ways to backup your online data from some of the most popular services like Diigo, Google and Evernote."
