  • Most educators agree that the one-size-fits-all curriculum needs addressing
  • emergence of technology in education has certainly created a renewed interest in personalizing learning and providing teachers with the tools necessary for differentiating curriculum.
  • True personalization requires more than just looking at achievement levels and trying to compensate for deficiencies
  • ...5 more annotations...
  • differentiation of content requires adding more depth and complexity to the curriculum rather than transmitting more or easier factual material.
  • achievement levels, information about student interests, learning styles, and preferred modes of expression allow us to make decisions about personalization that take multiple dimensions of the learner into account.
  • Respect for learning-style variations can be achieved by using instructional strategies such as simulations, Socratic inquiry, problem-based learning, dramatizations, and individual and small-group investigations of real problems. Expression-style preferences can be accommodated by giving students opportunities to communicate visually, graphically, artistically, and through animatronics, multimedia, and various community-service involvements.
  • Our obsession with content mastery and Skinner's behavioral theory of learning are slowly but surely giving way to an interest in personalization and differentiation.
  • While it is understandable that our early use of technology was mainly an adaptation of Gutenberg-online and a teaching-machine mentality of what learning is all about, we now have both the pedagogical rationale and technological capability to use the many dimensions of student characteristics that clearly and unequivocally result in higher engagement, enjoyment, and enthusiasm for learning.

      NO ONE is striving for this. Just the opposite.
  • Of greatest importance, however, is the status of our thinking, understanding how we think and the effect new technologies have on our cognitive processes. This debate extends beyond the neuroscience to questions relating to what is worth knowing and what mental functions are worth preserving at their present level of development
  • As a senior high school teacher, one of my greatest bugbears is the reluctance of students to reflect on the information they have collected and plan their essays. Rather, some expect to Google their entire essay, often skipping from one hyperlink to the next until they find something that appears to be relevant, then pasting it into their essay, frequently oblivious to academic honesty and coherence of argument. The ability to discern reliability of sources is also severely lacking

      This is a by-product of failing to address and teach good research methods in a digital world and assigning work that can simply be cut and pasted. We must move beyond "reporting" in a digital, information-rich, and connected world.
  • A primary role of educators is to foster qualities that are distinctly human: our ability to reflect, reason and imagine

      Exactly... and this must happen, regardless of the types of information that we have access to. To say that technology impedes this is laughable.
  • In the curricula of tomorrow this may entail identifying topics and tasks that begin with an instruction to turn all electronic devices off.
    • Steve Ransom
      Steve Ransom on 13 Oct 10
       
      No- it should begin with teachers establishing and negotiating meaningful, interesting, and powerful learning opportunities with access to all available tools. The computer as a learning tool is meant to extend physical human capabilities, not weaken them. It is the low-level, rote tasks that we require that weaken them. It's time to recognize this and wake up. Blaming the technology does little more than preserve the status quo.

  • Education, particularly K-12 education, remains relatively untouched by advances in our understanding of how people learn, how to design instruction that incorporates those insights, and the explosion in information technologies such as low-cost smartphones and tablets, cloud computing, broadband networks, speech recognition and speech synthesis, predictive analytics, data mining, machine learning, intelligent tutors, simulations, games, computer-[supported] collaborative work, and many other technologies.

    The above figure is the landscape of ~40,000 student submissions to the same programming assignment on Coursera's Machine Learning course. Nodes represent submissions and edges are drawn between syntactically similar submissions. Colors correspond to performance on a battery of unit tests (with red submissions passing all unit tests). In particular, clusters of similarly colored nodes correspond to multiple similar implementations that behaved in the same way (under unit tests).

    "Artificial Intelligence is a hot topic at the moment, with estimates varying wildly about how many jobs will be replaced by machine learning algorithms. Whatever the outcome, in reality, it is clear that schools will need to change, in order to prepare their students for the resulting impact on society and the skills needed for future employment."

    As technology evolves and its inner workings increasingly disappear from view, replaced with solid-state parts hidden by glass, aluminium and plastic, our understanding of what makes the world operate is similarly impeded. When machinery from just a few decades ago is viewed a world of moving parts, linkages, cogs and levers is revealed. These mechanical objects contain an inherent beauty and inspire curiosity in ways that modern devices with their pristine surfaces and simplified design language do not. Opportunities to explore devices from the past open our eyes and lead us to new questions of how our devices function, how machines do the jobs we need them to do and how engineers solve problems.

broadband education

  • Economists are trying to measure a home computer’s educational impact on schoolchildren in low-income households.
  • little or no educational benefit is found. Worse, computers seem to have further separated children in low-income households, whose test scores often decline after the machine arrives, from their more privileged counterparts.
  • few children whose families obtained computers said they used the machines for homework. What they were used for — daily — was playing games.
  • ...4 more annotations...
  • “Scaling the Digital Divide,” published last month, looks at the arrival of broadband service in North Carolina between 2000 and 2005 and its effect on middle school test scores during that period. Students posted significantly lower math test scores after the first broadband service provider showed up in their neighborhood, and significantly lower reading scores as well when the number of broadband providers passed four.
  • The expansion of broadband service was associated with a pronounced drop in test scores for black students in both reading and math, but no effect on the math scores and little on the reading scores of other students.
  • THE one area where the students from lower-income families in the immersion program closed the gap with higher-income students was the same one identified in the Romanian study: computer skills.
  • How disappointing to read in the Texas study that “there was no evidence linking technology immersion with student self-directed learning or their general satisfaction with schoolwork.”

shared by Maureen Greenbaum on 05 Jul 16 - No Cached
  • “A generation of children has grown up with continuous connectivity to the internet. A few years ago, nobody had a piece of plastic to which they could ask questions and have it answer back. The Greeks spoke of the oracle of Delphi. We’ve created it. People don’t talk to a machine. They talk to a huge collective of people, a kind of hive. Our generation [Mitra is 64] doesn’t see that. We just see a lot of interlinked web pages
  • “Within five years, you will not be able to tell if somebody is consulting the internet or not. The internet will be inside our heads anywhere and at any time. What then will be the value of knowing things? We shall have acquired a new sense. Knowing will have become collective.”
  • if you imagine me and my phone as a single entity, yes. Very soon, asking somebody to read without their phone will be like telling them to read without their glasses.”
  • ...4 more annotations...
  • Twenty children are asked a “big question” such as “Why do we learn history?”, “Is the universe infinite?”, “Should children ever go to prison?” or “How do bees make honey?” They are then left to find the answers using five computers. The ratio of four children to one computer is deliberate: Mitra insists that the children must collaborate. “There should be chaos, noise, discussion and running about,” he says.
  • . Year 4 children (aged eight to nine) were given questions from GCSE physics and biology papers. After using their Sole computers for 45 minutes, their average test scores on three sets of questions were 25%, 26% and 13%. Three months later – the school having taught nothing on these subjects in the interim – they were tested again, individually and without warning. The scores rose to 57%, 80% and 16% respectively, suggesting the children continued researching the questions in their own time.
  • he says the main benefit of his methods is that children’s self-confidence increases so that they challenge adult perceptions.
  • the propositions that children can benefit from collaborative learning and that banning internet use from exams will get trickier, to the point where it may prove futile. It’s worth remembering that new technologies nearly always deliver less than we expect at first and far more than we expect later on, often in unexpected ways.

  • What would an exceptional middle and high school computer science curriculum include?
  • This isn't a complete answer, but one thing the very first introductory classes should require is that the students turn off all their electronic computers and actually learn to walk through  algorithms with a computer that exists only on paper. (Or, I suppose, a whiteboard or a simulator.) This exercise would give the students a grounding in what is going on inside the computer as a very low level.My first computer programming class in my Freshman year of high school was completely on paper. Although it was done because the school didn't have much money, it turned out to be very beneficial.Another class I had in high school, that wouldn't normally be lumped into a Computer Science curriculum but has been a boon to my career, was good old Typing 101.
  • If you followed the CS Unplugged curriculum your students would know more about CS than most CS grads:http://csunplugged.orgIt's a really great intro to basic computer science concepts and very easy for students to understand.  Best of all you don't even need a computer per student if your school doesn't have the budget,
  • ...6 more annotations...
  • For younger students, I think that the ability to make something professional-looking, like a real grown-up would, is paramount.  Sadly, I think this means that LOGO and BASIC aren't much use any more*.
  • So, we have a few choices.  You can try to write phone apps that look just like real phone apps, design interactive websites that look just like real interactive websites, or do something with embedded systems / robotics.  Avoid the temptation to make these things into group projects; the main thing every student needs to experience is the process of writing code, running it, debugging it, and watching the machine react to every command.
  • It is important to consider what an 11 to 18-year old is familiar with in terms of mathematics and logical thinking. An average 11-year old is probably learning about fractions, simple cartesian geometry, the concept of units, and mathematical expressions. By 15, the average student will be taking algebra, and hopefully will have the all-important concept of variables under his/her belt. So much in CS is dependent on solid understanding that symbols and tokens can represent abstract concepts, values, or algorithms. Without it, it's still possible to teach CS, but it must be done in a very different way (see Scratch).
  • At this point, concepts such as variables, parenthesis matching, and functions (of the mathematical variety) are within easy reach. Concepts like parameter passing, strings and collections, and program flow should be teachable. More advanced concepts such as recursion, references and pointers, certain data structures, and big-O may be very difficult to teach without first going through some more foundational math.
  • I tend to agree strongly with those that believe a foundational education should inspire interest and enforce concepts and critical thinking over teaching any specific language, framework, system, or dogma.
  • The key is that the concepts in CS aren't just there for the hell of it. Everything was motivated by a real problem, and few things are more satisfying than fixing something you really want to work with a cool technique or concept you just learned.

      Why would they? It is PEOPLE, not programs or 'things' that make a difference!
  • An organization’s natural instinct is to cram the innovation into its existing operating model to sustain what it already does. This is the predictable course, the logical course—and the wrong course.

      This idea of 'nonconsumption' is exactly what the authors of Blended discuss. This is the opportune moment to disrupt and innovate. 
  • The way to implement an innovation so that it will transform an organization is to implement it disruptively—not by using it to compete against the existing paradigm and serve existing customers, but to let it compete against “non-consumption,” where the alternative is nothing at all.
  • ...2 more annotations...
  • At first glance there appears to be little non-consumption of education in the United States since students are required to receive schooling. Looking deeper, however, reveals many pockets of non-consumption where students would be delighted with computer-based learning rather than the alternative, nothing at all. Take Advanced Placement (AP) courses for starters. According to a 2005 report by the National Center for Education Statistics (NCES), 33 percent of schools nationwide offered no AP classes in 2002–03. Those that do provide AP courses today only offer a fraction of the 34 courses for which AP exams are available, because they lack the resources to hire more AP teachers or there is not enough student demand to justify a dedicated course and teacher.
  • Credit recovery is another big opportunity.
