Science Says This Is How Stress Kills Your Motivation | Inc.com - 0 views

  •  
    "Achieving success typically means keeping a solid grip on your motivation. Otherwise, long-haul projects fizzle fast as you encounter the strain of regular challenges.  But scientists from Emory University now say that chronic inflammation is a huge troublemaker, and that it might interfere with your drive to persist and explore. According to their new theory, detailed in the paper Can't or Won't? Immunometabolic Constraints on Dopaminergic Drive, chronic inflammation puts a squeeze on your brain's dopamine supply. You probably know dopamine best for its role in helping you feel happy, but it's a chemical that keeps your brain seeking novelty, too."

Why Computer Science Should Be a High School Graduation Requirement - The Tech Edvocate - 2 views

  •  
    "Computing is an integral part of every aspect of our lives, from how we connect with each other to the way we do our jobs and get around. Computing is the number one source of all new wages in the U.S. economy and there are currently 500,000 open computing jobs across the country. Yet, according to a Code.org report, only 15 states require all high schools to offer computer science. Many parents, educators, and education institutions are calling for computer science to be a high school graduation requirement. As one commentator pointed out: Schools teach math to students regardless of whether they want to become mathematicians because it is foundational. The same is true of computer science. There are a number of benefits to taking computer science in high school."

Suite Science Practices: Models | Mo Physics Mo Problems - 1 views

  •  
    "Over the past year, I have been gradually working to implement the Next Generation Science Standards (NGSS) into my classroom. Our new Wisconsin State Science Standards were designed with the NGSS in mind. They align very well, so please forgive me if my language focuses on the NGSS in this post. As I design lessons aligned the standards, I am considering to the skills students will be implementing that carry across multiple units. This relates to the Science and Engineering Practices contained in the standards. I am looking at the technology tools that can be used to leverage these practices. While there are 8 different practices and I hope to delve into each one and the technology tools that can help learners in each, this post will only focus on one practice. That practice is Developing and Using Models. As the name indicates, there a"

Algorithms, the Illusion of Neutrality - Towards Data Science - 0 views

  •  
    "Bias is a fundamental human characteristic. We are all biased, by our very nature, and every day we make countless decisions based on our gut feelings. We all have preconceived ideas, prejudices, and opinions. And that is fine, as long as we recognize it and take responsibility for it. The fundamental promise of AI, besides the dramatic increase of data processing power and business efficiency, is to help reduce the conscious or unconscious bias of human decisions. At the end of the day, this is what we expect from algorithms, isn't it? Objectivity, mathematical detachment rather than fuzzy emotions, fact-based rather than instinctive decisions. Algorithms are supposed to alert people to their cognitive blind spots, so they can make more accurate, unbiased decisions. At least that's the theory…"

Why leveraging computer science is crucial to every classroom | eSchool News - 2 views

  • 1. Personalized learning
  • By helping students develop skills of inquiry, ideating, creating, modeling, testing, and analyzing in the early years, it becomes easier to integrate computer science into the classroom in later years.
  •  
    "In the ever-changing technological world, computer science is not only becoming more prominent in classrooms, but a staple in education. Computer science combines the principles of technology and use of computers to educate learners on both the hardware and software of computer technology. The field of computer science is exceptionally diverse, as the skill sets are in-demand across practically every industry-serving as a lucrative and stable career pathway. In addition, computer science has many facets, meaning educators can leverage various components of the field to reach students across all levels and learning abilities. With technology present in almost every classroom, educators have a greater opportunity to implement computer science lessons throughout the curriculum. This provides students with the knowledge and skills required to help follow job market trends when they graduate."

Computers + Emotional Care = a Great Match | Teacher Single Post - 2 views

  •  
    "Recently, my students gave me one of those golden moments in teaching.  Allow me to set the stage. We were over six weeks into a project-based life science unit in which students apply systems-thinking to closely examine the inner workings of a body system and relate that system to others as a subsystem. The set of standards housing our work is juicy with Crosscutting Concepts and ripe with potential for Science and Engineering Practices.  We began the unit exploring how cells themselves, a structure students often initially perceive as an end-all-be-all baseline to life, are instead a very complex system of subsystems.  That particular day, students were outlining components of their selected body system in preparation for writing  a podcast."

What I Learned from Writing a Data Science Article Every Week for a Year - 1 views

  •  
    "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.""

    "Last month, TIME and Felix & Paul Studios launched VR cameras to the International Space Station (ISS) in a new project to bring viewers an intimate look aboard one of the most exclusive places in human existence. Dubbed The ISS Experience, over the course of the next year VR cameras will provide what the makers call "unprecedented access to a participatory experience-one that will culminate with the first-ever filming of a spacewalk in cinematic virtual reality." The year-long project was announced at the Sundance Film Festival in Park City, Utah this weekend. The project's first VR scene was filmed on Friday, January 25th."

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."

Critical Thinking Skills to Help Students Better Evaluate Scientific Claims | MindShift... - 1 views

  •  
    "Michelle Joyce doesn't shy away from politicized science topics such as climate change. In fact, she works to equip seniors at Palmetto Ridge High School in Naples, Florida with the skills to accurately evaluate those topics on their own. Along with teaching chemistry and physics, she offers a class called "thinking skills" where students solve logic and math puzzles while also enhancing their media literacy. Students go beyond just learning about legitimate sources of information on the internet and delve into just how the information is put together in the first place. But teaching students those critical thinking skills only as they're about to depart for college can be too little too late. "It's a really hard thing to teach within the space of everything else that you need to teach in a classroom," Joyce said. "It's crucial that we teach it as early as we can." The internet has no shortage of dubious information; and the ability to evaluate health and science claims is a subset of media literacy. With the abundance of health/science content students may only see via social media, kids are ill-equipped to discern hype from real science."
