Educational Leadership:Teaching for the 21st Century:What Would Socrates Say? - 0 views

  • The noted philosopher once said, "I know nothing except the fact of my ignorance." My fear is that instead of knowing nothing except the fact of our own ignorance, we will know everything except the fact of our own ignorance. Google has given us the world at our fingertips, but speed and ubiquity are not the same as actually knowing something.
  • Socrates believed that we learn best by asking essential questions and testing tentative answers against reason and fact in a continual and virtuous circle of honest debate. We need to approach the contemporary knowledge explosion and the technologies propelling this new enlightenment in just that manner. Otherwise, the great knowledge and communication tsunami of the 21st century may drown us in a sea of trivia instead of lifting us up on a rising tide of possibility and promise.
  • A child born today could live into the 22nd century. It's difficult to imagine all that could transpire between now and then. One thing does seem apparent: Technical fixes to our outdated educational system are likely to be inadequate. We need to adapt to a rapidly changing world.

  • Every day we are exposed to huge amounts of information, disinformation, and just plain nonsense. The ability to distinguish fact from factoid, reality from fiction, and truth from lies is not a "nice to have" but a "must have" in a world flooded with so much propaganda and spin.
  • For example, for many years, the dominant U.S. culture described the settling of the American West as a natural extension of manifest destiny, in which people of European descent were "destined" to occupy the lands of the indigenous people. This idea was, and for some still is, one of our most enduring and dangerous collective fabrications because it glosses over human rights and skirts the issue of responsibility. Without critical reflection, we will continually fall victim to such notions.
  • A second element of the 21st century mind that we must cultivate is the willingness to abandon supernatural explanations for naturally occurring events.
  • The third element of the 21st century mind must be the recognition and acceptance of our shared evolutionary collective intelligence.
  • To solve the 21st century's challenges, we will need an education system that doesn't focus on memorization, but rather on promoting those metacognitive skills that enable us to monitor our own learning and make changes in our approach if we perceive that our learning is not going well.
  • Metacognition is a fancy word for a higher-order learning process that most of us use every day to solve thousands of problems and challenges.
  • We are at the threshold of a worldwide revolution in learning. Just as the Berlin Wall fell in 1989, the wall of conventional schooling is collapsing before our eyes. A new electronic learning environment is replacing the linear, text-bound culture of conventional schools. This will be the proving ground of the 21st century mind.
  • We will cease to think of technology as something that has its own identity, but rather as an extension of our minds, in much the same way that books extend our minds without a lot of fanfare. According to Huff and Saxberg, immersive technologies—such as multitouch displays; telepresence (an immersive meeting experience that offers high video and audio clarity); 3-D environments; collaborative filtering (which can produce recommendations by comparing the similarity between your preferences and those of other people); natural language processing; intelligent software; and simulations—will transform teaching and learning by 2025.
  • So imagine that a group of teachers and middle school students decides to tackle the question, What is justice? Young adolescents' discovery of injustice in the world is a crucial moment in their development. If adults offer only self-serving answers to this question, students can become cynical or despairing. But if adults treat the problem of injustice truthfully and openly, hope can emerge and grow strong over time. As part of their discussion, let's say that the teachers and students have cocreated a middle school earth science curriculum titled Water for the World. This curriculum would be a blend of classroom, community, and online activities. Several nongovernmental organizations—such as Waterkeeper, the Earth Institute at Columbia University, and Water for People—might support the curriculum, which would meet national and state standards and include lessons, activities, games, quizzes, student-created portfolios, and learning benchmarks.
  • The goal of the curriculum would be to enable students from around the world to work together to address the water crisis in a concrete way. Students might help bore a freshwater well, propose a low-cost way of preventing groundwater pollution, or develop a local water treatment technique. Students and teachers would collaborate by talking with one another through Skype and posting research findings using collaborative filtering. Students would create simulations and games and use multitouch displays to demonstrate step-by-step how their projects would proceed. A student-created Web site would include a blog; a virtual reference room; a teachers' corner; a virtual living room where learners communicate with one another in all languages through natural language processing; and 3-D images of wells being bored in Africa, Mexico, and Texas. In a classroom like this, something educationally revolutionary would happen: Students and adults would connect in a global, purposeful conversation that would make the world a better place. We would pry the Socratic dialogue from the hands of the past and lift it into the future to serve the hopes and dreams of all students everywhere.
  • There has never been a time in human history when the opportunity to create universally accessible knowledge has been more of a reality. And there has never been a time when education has meant more in terms of human survival and happiness.
  • To start, we must overhaul and redesign the current school system. We face this great transition with both hands tied behind our collective backs if we continue to pour money, time, and effort into an outdated system of education. Mass education belongs in the era of massive armies, massive industrial complexes, and massive attempts at social control. We have lost much talent since the 19th century by enforcing stifling education routines in the name of efficiency. Current high school dropout rates clearly indicate that our standardized testing regime and outdated curriculums are wasting the potential of our youth.
  • If we stop thinking of schools as buildings and start thinking of learning as occurring in many different places, we will free ourselves from the conventional education model that still dominates our thinking.

2009 Horizon Report: The K12 Edition » Critical Challenges - 0 views

  • Students and teachers both are finding it necessary to be technologically adept, to be able to collaborate on a global scale and to understand content and media design.
  • Schools need to adapt to current student needs and identify new learning models that are engaging to younger generations.
  • To support such a change, both teaching practice and the tools used in the classroom must adapt. Assessment has also not kept pace with new modes of working, and must change along with teaching methods, tools, and materials.
  • ...3 more annotations...
  • Use of technology tools that are already familiar to students, project-based learning practices that incorporate real-life experiences, and mentoring from community members are a few practices that support increased engagement.
  • Technology tools that are part of everyday life for many students and working professionals should be seen as core tools of the teaching profession that teachers are required to master as any professional would master the tools of his or her trade.
  • Learners have increasing opportunities to take their education into their own hands, and options like informal education, online education, and home-based learning are attracting students away from traditional educational settings. If the system is to remain relevant it must adapt, but major change comes hard in education.

Teacher Professional Development Sourcebook: The Changing Landscape of Teacher Learning - 8 views

  • So the challenge is to find ways to create online teacher professional development that seems both compelling in its content and also more convenient, easier to fit into the work life of a teacher than the face-to-face courses.
  • online teacher professional development that includes an asynchronous component helps with that kind of reflection. Plus, the online format provides a layer of distance that helps people feel more willing to share things that are a little bit risky than they might in a face-to-face environment.
  • I think the kinds of professional development that involve people sharing artifacts of their practice and talking about them within a larger conceptual framework are becoming more and more popular with teachers.
  • ...2 more annotations...
  • The first is that it’s easier to do online professional development at scale than it is with local or purely face-to-face professional development.
  • I think this financial crunch is going to force people to move to some other model—one that probably uses a lot of technology,

    Biological irradiators are specialized devices that deliver controlled doses of ionizing radiation to biological samples, such as cells, tissues, and small organisms. These tools are invaluable in cell and molecular biology research for a variety of applications. 1. Cell Cycle and Apoptosis Research Cell Cycle Arrest: Ionizing radiation can induce cell cycle arrest at specific checkpoints, allowing researchers to study the regulation of the cell cycle and the role of various proteins in cell cycle control. Apoptosis Induction: Radiation can trigger programmed cell death (apoptosis), providing a model to study the molecular pathways involved in apoptosis and the role of different genes and proteins in this process.
