Where Edtech Can Help: 10 Most Powerful Uses of Technology for Learning - InformED : - 2 views

  •  
    "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

A Guide to Coding and Computational Thinking Across the Curriculum | K-6 Educational Re... - 2 views

  •  
    "Computational thinking is the thought processes involved in formulating a problem and expressing its solution(s) in such a way that a computer - human or machine - can effectively carry out. Informally, computational thinking describes the mental activity in formulating a problem to admit a computational solution.  The solution can be carried out by a human or machine. This latter point is important.  First, humans compute.  Second, people can learn computational thinking without a machine.  Also, computational thinking is not just about problem solving, but also about problem formulation.1 The Digital Careers organisation says that students need experience and skills in computational thinking and computer programming (coding) to be successful in their future careers.2 The NSW syllabuses provide a range of opportunities to develop students' understanding of computational thinking and coding. This guide draws out the areas where computational thinking can be applied within the existing NSW K-8 syllabuses. Like the syllabuses, it is organised into stages of learning and subdivided into learning areas, with suggested activities and links to online resources. Not all resources and activities listed in this guide refer to coding explicitly, but they do aim to develop algorithmic and computational thinking skills to better enable students and teachers to reach a coding goal."

Teaching computational thinking without using a computer | Technology for Learners - 3 views

  •  
    "omputational thinking is one of the core objectives that runs through the computing program of study in England from Key Stage 1 to Key Stage 4. Before computers can be used to solve a problem, computational thinking refers to understanding the problem itself and the ways in which it could be resolved. Software engineers and computer scientists for example, routinely engage in computational thinking. As a higher order thinking skill, computational thinking has applications both across and beyond the school curriculum. There are four key techniques to computational thinking: Abstraction - focusing on the important information only, ignoring irrelevant details Algorithms - developing a step-by-step solution to the problem Decomposition - breaking down the problem into smaller, more manageable parts Logic - looking for similarities among and within problems Learning to program is one of the best ways to develop computational thinking, as it uses each one of these techniques. My intention here is to show an example of a lesson in which computational thinking is taught at Key Stage 1 (5 to 7 years) through programming. I took the lesson plan (attached above) from The Barefoot Computing Project and I taught it to my 1st grade class last week.  It required the children to work in pairs to create step-by-step instructions through pictures.  The pairs then swapped each other's instructions, which they used to draw the 'crazy character' that the other child had in mind."

Design thinking vs computational thinking in education - 3 views

  •  
    "In India, 41km of highway road was constructed every day for the year of 2016. In the Indian government budget, it estimated the cost just for 2016 to be 19 billion USD. It would be financing any shortfall through tax-free government bonds. Computational thinking would have played an instrumental role in deciding on where the road would go through with taking into account the key hubs and may have saved the government millions, if not billions of dollars. Jeanette Wing (2012) defines computational thinking as the thought process involved in formulating a problem and expressing its solution in a way that a computer-human or machine can effectively carry out. It is the process of abstraction by; choosing the right abstractions, operating in terms of multiple layers of abstraction simulations and defining the relationships between layers guided by efficiency, correctness, and flexibility. Computational thinking can best be related to as writing software or instructionals. Every action or non-action is accounted for in the way computational artifacts are constructed. Computational thinking is great for working out a solution but there is an argument that computational thinking does not put enough emphasis on the problem itself. Design thinking, on the other hand, attempts to understand the intent or problem before looking at any solution - computational or otherwise. Design thinking attempts to identify why the problem exists in the first place before solving it. IDEO defines design thinking as the application of empathy and experimentation to arrive at innovation solutions through making decisions based on stakeholder input and evidence based research. Using the Indian roading example, a design thinker would ask, what is the intent of building the roads in the first place?"

It's Time to Weave Computational Thinking into K-12 -- THE Journal - 2 views

  •  
    "It's high time for students to move beyond an hour of coding exercises and learn computational thinking. That's the message of a new report from Digital Promise that examines what's important to know and be able to do in a "computational world." Digital Promise is a non-profit that that promotes the use of innovation in education, particularly as it uses digital technologies. The new report, "Computational Thinking for a Computational World," explains its theme of computational thinking by borrowing a description from a long-ago article published by the Association for Computing Machinery: It is "a way of solving problems, designing systems and understanding human behavior that draws on concepts fundamental to computer science… a fundamental skill for everyone, not just computer scientists." More simply, the report noted, "The skill required to tell a computer what to do is programming. The thought process behind programming is computational thinking." What it isn't is humans thinking like computers. And, according to the report's authors, it's something that needs to be taught across subjects in K-12 schools."

Integrating Computational Thinking into Your Elementary Classroom - 2 views

  •  
    "Computer science education is not a new field. Much of what we know about the pedagogy and content for elementary students comes from Seymour Papert's research on teaching elementary students to code back in the 1970's and 80's. But, as we shift from labs and one-off classrooms to a broad expansion for all students in every classroom K-12, we are seeing changes to how computer science is taught. This means we are working in a rapidly evolving field (insert metaphor of building a plane while flying it). Over time, we have gone from a focus on coding (often in isolation) to a more broad idea of computer science as a whole, and now to the refined idea of computational thinking as a foundational understanding for all students. Pause. You may be asking, "But wait, what's computational thinking again?" In her book Coding as a Playground, Marina Umaschi Bers explained: "The notion of computational thinking encompasses a broad set of analytic and problem-solving skills, dispositions, habits, and approaches most often used in computer science, but that can serve everyone." More simply, you can think of computational thinking as the thought processes involved in using algorithms to solve problems. Sheena Vaidyanathan writes some good articles explaining the differences between computer science, coding, and computational thinking here and here."

"Computational Thinking and Literacy" by Sharin Rawhiya Jacob and Mark Warschauer - 3 views

  •  
    "Today's students will enter a workforce that is powerfully shaped by computing. To be successful in a changing economy, students must learn to think algorithmically and computationally, to solve problems with varying levels of abstraction. These computational thinking skills have become so integrated into social function as to represent fundamental literacies. However, computer science has not been widely taught in K-12 schools. Efforts to create computer science standards and frameworks have yet to make their way into mandated course requirements. Despite a plethora of research on digital literacies, research on the role of computational thinking in the literature is sparse. This conceptual paper proposes a three dimensional framework for exploring the relationship between computational thinking and literacy through: 1) situating computational thinking in the literature as a literacy; 2) outlining mechanisms by which students' existing literacy skills can be leveraged to foster computational thinking; and 3) elaborating ways in which computational thinking skills facilitate literacy development."

Computational Thinking: 10 Ways To Promote CT Across The Curriculum, Part 1 - Tech Lear... - 5 views

  •  
    "In this post, I would like to review a thinking processes that can be applied across the curriculum providing a process for authentic understanding of standards. The cognitive process I am referring to is Computational Thinking (CT). This type of thinking is important not just in high stake testing, but also success in that world after school. Perhaps you have come across the idea of computational thinking in education. The best way to describe computational thinking is to look at the way a computer thinks… or at least runs a program. This is actually the most important concept a student learns through coding and developing computer programs. We must keep in mind that it is not the coding that is important… but the thinking process. After all… one can use a computer, but not actually use computational thinking skills. "

Computational thinking, 10 years later - Microsoft Research - 1 views

  •  
    "Think back to 2005. Since the dot-com bust, there had been a steep and steady decline in undergraduate enrollments in computer science, with no end in sight. The computer science community was wringing its hands, worried about the survival of their departments on campuses. Unlike many of my colleagues, I saw a different, much rosier future for computer science. I saw that computing was going to be everywhere. I argued that the use of computational concepts, methods and tools would transform the very conduct of every discipline, profession and sector. Someone with the ability to use computation effectively would have an edge over someone without. So, I saw a great opportunity for the computer science community to teach future generations how computer scientists think. Hence "computational thinking." I must admit, I am surprised and gratified by how much progress we have made in achieving this vision: Computational thinking will be a fundamental skill used by everyone in the world by the middle of the 21st century. By fundamental, I mean as fundamental as reading, writing and arithmetic."

Why We Must Teach Our Teachers Computational Thinking - The Tech Edvocate - 0 views

  •  
    "Computational thinking isn't new. Three decades ago, Seymour Papert introduced computational thinking when he developed the concept of bricolage, which is the construction of something new from many sources. He rightly understood the significance of computers, and with computational thinking, he surmised that they would not only be an integral part of our educational process, but we would need to acquire new ways for learning when using computers. In essence, the bricoleur builds knowledge by engaging in a process of building precise steps that encourage the construction of knowledge. Papert recognized that over time, the learner's theory may change as the result of refining his or her responses in any of the four stages of computational thinking. Even before Papert's work, however, educational visionaries insisted that the way to solve problems in any field was by adopting sequential problem-solving methods, which became algorithmic or computational thinking. In short, we use computational thinking (CT) to solve problems."

7 computational thinking strategies to help young innovators fail forward | eSchool News - 4 views

  •  
    "Computational thinking has been trending, but what is it, really? Simply put, computational thinking is a method of reasoning that teaches students how to solve real-world, complex problems with strategies that computers use. Computational thinking and the design thinking process are frameworks for problem-solving to help address the need for 21st-century skills across our nation's K-12 school system. While computation governs the world around us, computational thinking as a teaching and learning framework is a new concept for many. These skills are becoming progressively important due to the constant evolution of technology and its place in our economy. An increasingly automated workforce means students who have had exposure to tech-thinking will be more likely to succeed. To help get students future-ready, I've identified seven effective thinking strategies to equip young innovators with valuable problem-solving abilities. Using these tips, students will not only be learning important skills, but will be preparing for what lies ahead post-graduation."

PBS Show Will Teach Preschoolers How To Think Like Computers | EdSurge News - 0 views

  •  
    "As society anticipates a future filled with artificial intelligence, experts are theorizing ways that we humans can outperform the computers that are being programmed to perfection. Some believe educators should focus on building soft skills like empathy and interpersonal communication so humans and robots can complement one another. However, other education thought leaders are ready to beat computers at their own game by teaching people to think like intelligent machines. Why do so many of our kids struggle with math problem-solving? Because they don't know where to start; they don't know how to decompose the problem. Heidi Williams The term for getting humans to think like computers has been coined Computational Thinking, and the idea is taking off. Author Heidi Williams can attest to its popularity after her book on the subject, No Fear Coding Computational Thinking Across the K-5 Curriculum, sold out at the International Society for Technology in Education conference. Inside the book, Williams breaks down computational thinking standards into four parts: 1. Formulating problems through data analysis, abstract models and algorithmic thinking; 2. Collecting, analyzing and presenting data; 3. Breaking down problems into parts and extracting information to understand the system in place; and 4. Using algorithmic thinking to develop sequences and testing automated solutions."

Is Coding the New Literacy? | Mother Jones - 2 views

  • What if learning to code weren't actually the most important thing? It turns out that rather than increasing the number of kids who can crank out thousands of lines of JavaScript, we first need to boost the number who understand what code can do. As the cities that have hosted Code for America teams will tell you, the greatest contribution the young programmers bring isn't the software they write. It's the way they think. It's a principle called "computational thinking," and knowing all of the Java syntax in the world won't help if you can't think of good ways to apply it.
  • Researchers have been experimenting with new ways of teaching computer science, with intriguing results. For one thing, they've seen that leading with computational thinking instead of code itself, and helping students imagine how being computer savvy could help them in any career, boosts the number of girls and kids of color taking—and sticking with—computer science. Upending our notions of what it means to interface with computers could help democratize the biggest engine of wealth since the Industrial Revolution.
  • 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.

  • Because as programmers will tell you, the building part is often not the hardest part: It's figuring out what to build. "Unless you can think about the ways computers can solve problems, you can't even know how to ask the questions that need to be answered," says Annette Vee, a University of Pittsburgh professor who studies the spread of computer science literacy.

    "Unfortunately, the way computer science is currently taught in high school tends to throw students into the programming deep end, reinforcing the notion that code is just for coders, not artists or doctors or librarians. But there is good news: Researchers have been experimenting with new ways of teaching computer science, with intriguing results. For one thing, they've seen that leading with computational thinking instead of code itself, and helping students imagine how being computer savvy could help them in any career, boosts the number of girls and kids of color taking-and sticking with-computer science.

5 core computational thinking skills that strengthen humanities skills | eSchool News - 1 views

  •  
    "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:"

All kids should have a computer science education - Baltimore Sun - 0 views

  •  
    "Like most students at the time, I did not have access to computer science classes when I attended Wilde Lake High School in Columbia during the 1980s. I only stumbled upon the field when my high school math teacher recommended that I take a FORTRAN programming course at Howard Community College. I quickly learned that programming was like nothing I had experienced in school before. Whenever I finally solved a problem, there was a deeply satisfying "aha!" moment. As a result, I studied computer science at Harvard and received my Ph.D. in the field from the University of California, Berkeley. Nearly four decades after I took that first FORTRAN class, I'm a professor of computer science and associate dean at the University of Maryland, Baltimore County. I was fortunate to have found my passion, even though computer science was not taught at my school. The unfortunate fact is that most K-12 schools still do not teach computer science, and most of today's high school and college students - particularly women - have still had little or no exposure to computational thinking, coding or computer science. There are certainly many students who would make great computer scientists, or who could leverage computing skills to achieve success in any number of other fields, who never take a single related class. Even in Maryland, one of the most technologically advanced states in the nation, only 14 percent of students take a computer science class in high school, and nearly half of the public high schools do not offer any AP computer science classes."

Computational Fluency - Mitchel Resnick - Medium - 2 views

  •  
    "Over the past decade, there has been much discussion of the term computational thinking. The term, popularized by computer scientist Jeannette Wing, is generally used to describe computer-science concepts and strategies that can be useful in understanding and solving problems in a wide range of disciplines and contexts. In a growing number of schools around the world, there are now efforts to help students develop as computational thinkers. In our Lifelong Kindergarten research group at the MIT Media Lab, we prefer to focus on the idea of computational fluency rather than computational thinking. Why? We want to highlight the importance of children developing as computational creators as well as computational thinkers. In our view, computational fluency involves not only an understanding of computational concepts and problem-solving strategies, but also the ability to create and express oneself with digital technologies."

Extending Computer Science Education Week with Computational Thinking - Digital Promise - 2 views

  •  
    "This week is Computer Science Education Week, and millions of students across the United States will participate in an Hour of Code. Over the last four years, the Hour of Code has been instrumental in offering children the opportunity to try coding. Computer science, however, is much more than just coding, and students need much more time to learn and practice computing skills and dispositions to be prepared for the world in which they're growing up. These skills and dispositions of a computer scientist are commonly referred to as "computational thinking" and increasingly, computational thinking is being introduced to students within the subjects they study every day."

    The K-12 Computer Science Framework was developed for states, districts, schools, and organizations to inform the development of standards and curriculum, build capacity for teaching computer science, and implement computer science pathways. The framework Computer science is powering approaches to many of our world's toughest challenges. The K-12 Computer Science Framework informs standards and curriculum, professional development, and the implementation of computer science pathways. 2 K-12 Computer Science Framework Executive Summary promotes a vision in which all students critically engage in computer science issues; approach problems in innovative ways; and create computational artifacts with a practical, personal, or societal intent. The development of the framework was a community effort. Twenty-seven writers and twenty-five advisors developed the framework with feedback from hundreds of reviewers including teachers, researchers, higher education faculty, industry stakeholders, and informal educators. The group of writers and advisors represents states and districts from across the nation, as well as a variety of academic perspectives and experiences working with diverse student populations.

What's the Difference Between Coding and Computational Thinking? | EdSurge News - 1 views

  • Let’s get into a simple, but longer definition. When given any problem, can we formulate it so that it can solved using the power of computers? A computational thinker is one who collects data and analyzes it to understand the problem. That person then decomposes (breaks it down) into simpler problems. Instead of solving only that problem, you look for patterns, remove details and abstract so you can solve all problems of that type. You define the steps to solve the problem (the algorithm) and if possible, build a model to simulate, test and debug the solution.
  •  
    "In my last EdSurge article, "Computer Science Goes Beyond Coding," I wrote about the difference between coding and computer science, to help us understand what we mean by phrases like "Teach kids to code" and "Computer science for all." In that article and in many other articles, there is another term that appears often: "Computational thinking." Well, what is Computational Thinking (CT), and how does it differ from Coding and Computer Science-especially when it comes to classroom practice and instruction?"
