Occupy Your Brain - 111 views

  • One of the most profound changes that occurs when modern schooling is introduced into traditional societies around the world is a radical shift in the locus of power and control over learning from children, families, and communities to ever more centralized systems of authority.
  • Once learning is institutionalized under a central authority, both freedom for the individual and respect for the local are radically curtailed.  The child in a classroom generally finds herself in a situation where she may not move, speak, laugh, sing, eat, drink, read, think her own thoughts, or even  use the toilet without explicit permission from an authority figure.
  • In what should be considered a chilling development, there are murmurings of the idea of creating global standards for education – in other words, the creation of a single centralized authority dictating what every child on the planet must learn.
  • ...26 more annotations...
  • In “developed” societies, we are so accustomed to centralized control over learning that it has become functionally invisible to us, and most people accept it as natural, inevitable, and consistent with the principles of freedom and democracy.   We assume that this central authority, because it is associated with something that seems like an unequivocal good – “education” – must itself be fundamentally good, a sort of benevolent dictatorship of the intellect. 
  • We endorse strict legal codes which render this process compulsory, and in a truly Orwellian twist, many of us now view it as a fundamental human right to be legally compelled to learn what a higher authority tells us to learn.
  • And yet the idea of centrally-controlled education is as problematic as the idea of centrally-controlled media – and for exactly the same reasons.
  • The First Amendment of the U.S. Constitution was designed to protect all forms of communication, information-sharing, knowledge, opinion and belief – what the Supreme Court has termed “the sphere of intellect and spirit” – from government control.
  • by the mid-19th century, with Indians still to conquer and waves of immigrants to assimilate, the temptation to find a way to manage the minds of an increasingly diverse and independent-minded population became too great to resist, and the idea of the Common School was born.
  • We would keep our freedom of speech and press, but first we would all be well-schooled by those in power.
  • A deeply democratic idea — the free and equal education of every child — was wedded to a deeply anti-democratic idea — that this education would be controlled from the top down by state-appointed educrats.
  • The fundamental point of the Occupy Wall Street movement is that the apparatus of democratic government has been completely bought and paid for by a tiny number of grotesquely wealthy individuals, corporations, and lobbying groups.  Our votes no longer matter.  Our wishes no longer count.  Our power as citizens has been sold to the highest bidder.
  • Our kids are so drowned in disconnected information that it becomes quite random what they do and don’t remember, and they’re so overburdened with endless homework and tests that they have little time or energy to pay attention to what’s happening in the world around them.
  • If in ten years we can create Wikipedia out of thin air, what could we create if we trusted our children, our teachers, our parents, our neighbors, to generate community learning webs that are open, alive, and responsive to individual needs and aspirations?  What could we create if instead of trying to “scale up” every innovation into a monolithic bureaucracy we “scaled down” to allow local and individual control, freedom, experimentation, and diversity?
  • The most academically “gifted” students excel at obedience, instinctively shaping their thinking to the prescribed curriculum and unconsciously framing out of their awareness ideas that won’t earn the praise of their superiors.  Those who resist sitting still for this process are marginalized, labeled as less intelligent or even as mildly brain-damaged, and, increasingly, drugged into compliance.
  • the very root, the very essence, of any theory of democratic liberty is a basic trust in the fundamental intelligence of the ordinary person.   Democracy rests on the premise that the ordinary person — the waitress, the carpenter, the shopkeeper — is competent to make her own judgments about matters of domestic policy, international affairs, taxes, justice, peace, and war, and that the government must abide by the decisions of ordinary people, not vice versa.  Of course that’s not the way our system really works, and never has been.   But most of us recall at some deep level of our beings that any vision of a just world relies on this fundamental respect for the common sense of the ordinary human being.
  • This is what we spend our childhood in school unlearning. 
  • If before we reach the age of majority we must submit our brains for twelve years of evaluation and control by government experts, are we then truly free to exercise our vote according to the dictates of our own common sense and conscience?  Do we even know what our own common sense is anymore?
  • We live in a country where a serious candidate for the Presidency is unaware that China has nuclear weapons, where half the population does not understand that Saddam Hussein had nothing to do with 9/11, where nobody pays attention as Congress dismantles the securities regulations that limit the power of the banks, where 45% of American high school students graduate without knowing that the First Amendment of the Constitution guarantees freedom of the press.   At what point do we begin to ask ourselves if we are trying to control quality in the wrong way?
  • Human beings, collaborating with one another in voluntary relationships, communicating and checking and counter-checking and elaborating and expanding on one another’s knowledge and intelligence, have created a collective public resource more vast and more alive than anything that has ever existed on the planet.
  • But this is not a paeon to technology; this is about what human intelligence is capable of when people are free to interact in open, horizontal, non-hierarchical networks of communication and collaboration.
  • Positive social change has occurred not through top-down, hierarchically controlled organizations, but through what the Berkana Institute calls “emergence,” where people begin networking and forming voluntary communities of practice. When the goal is to maximize the functioning of human intelligence, you need to activate the unique skills, talents, and knowledge bases of diverse individuals, not put everybody through a uniform mill to produce uniform results. 
  • You need a non-punitive structure that encourages collaboration rather than competition, risk-taking rather than mistake-avoidance, and innovation rather than repetition of known quantities.
  • if we really want to return power to the 99% in a lasting, stable, sustainable way, we need to begin the work of creating open, egalitarian, horizontal networks of learning in our communities.
  • They are taught to focus on competing with each other and gaming the system rather than on gaining a deep understanding of the way power flows through their world.
  • And what could we create, what ecological problems could we solve, what despair might we alleviate, if instead of imposing our rigid curriculum and the destructive economy it serves on the entire world, we embraced as part of our vast collective intelligence the wisdom and knowledge of the world’s thousands of sustainable indigenous cultures?
  • They knew this about their situation: nobody was on their side.  Certainly not the moneyed classes and the economic system, and not the government, either.  So if they were going to change anything, it had to come out of themselves.
  • As our climate heats up, as mountaintops are removed from Orissa to West Virginia, as the oceans fill with plastic and soils become too contaminated to grow food, as the economy crumbles and children go hungry and the 0.001% grows so concentrated, so powerful, so wealthy that democracy becomes impossible, it’s time to ask ourselves; who’s educating us?  To what end?  The Adivasis are occupying their forests and mountains as our children are occupying our cities and parks.  But they understand that the first thing they must take back is their common sense. 
  • They must occupy their brains.
  • Isn’t it time for us to do the same?
  •  
    Carol Black, creator of the documentary, "Schooling the World" discusses the conflicting ideas of centralized control of education and standardization against the so-called freedom to think independently--"what the Supreme Court has termed 'the sphere of intellect and spirit" (Black, 2012). Root questions: "who's educating us? to what end?" (Black, 2012).

    This is a must read. Carol Black echoes here many of the ideas of Paulo Freire, John Taylor Gatto and the like.

elearnspace. Connectivism: A Learning Theory for the Digital Age - 17 views

  • Over the last twenty years, technology has reorganized how we live, how we communicate, and how we learn.
    • Rose Molter
       
      I aggree that as teachers we need to realize that technology has changed instruction and the way that our students learn and the way that we learn and instruct.
    • Orlando Gonzalez
       
      Technology has always changed the way we live. How did we respond to changes in the past? One thought is that some institutions, some businesses disappeared, while others, who took advantage of the new tech, appeared to replace the old. It will happen again and we as educators need to lead the way.
    • Maureen Curran
       
      With technology our students brains are wired differently and they can multi-task and learn in multiple virtual environments all at once. This should make us think about how we present lessons, structure learning and keep kids engaged.
    • Mike Burnett
       
      Rubbish. The idea that digital native are adept at multitasking is wrong. They may be doing many things but the quality and depth is reduced. There is a significant body of research to support this. Development of grit and determination are key attributes of successful people. Set and demand high standards. No one plays sport or an instrument because it is easy rather because they can clearly see a link between hard work and pleasure.

  • Informal learning is a significant aspect of our learning experience.
  • Learning is a continual process, lasting for a lifetime.
  • Technology is altering (rewiring) our brains.
  • Connectivism is the integration of principles explored by chaos, network, and complexity and self-organization theories.
  • Principles of connectivism:
  • Learning and knowledge rests in diversity of opinions. Learning is a process of connecting specialized nodes or information sources. Learning may reside in non-human appliances. Capacity to know more is more critical than what is currently known Nurturing and maintaining connections is needed to facilitate continual learning. Ability to see connections between fields, ideas, and concepts is a core skill. Currency (accurate, up-to-date knowledge) is the intent of all connectivist learning activities. Decision-making is itself a learning process. Choosing what to learn and the meaning of incoming information is seen through the lens of a shifting reality. While there is a right answer now, it may be wrong tomorrow due to alterations in the information climate affecting the decision.
    • Rose Molter
       
      I think it is important for us to realize the importance of connections.
  • The organization and the individual are both learning organisms.
  • Classrooms which emulate the “fuzziness”

  • The ability to draw distinctions between important and unimportant information is vital.
  • Behaviorism, cognitivism, and constructivism do not attempt to address the challenges of organizational knowledge and transference.
  • The health of the learning ecology of the organization depends on effective nurturing of information flow.
  • This cycle of knowledge development (personal to network to organization) allows learners to remain current in their field through the connections they have formed.
  • This amplification of learning, knowledge and understanding through the extension of a personal network is the epitome of connectivism.
  • Diverse teams of varying viewpoints are a critical structure for completely exploring ideas
  • An organizations ability to foster, nurture, and synthesize the impacts of varying views of information is critical to knowledge economy surviva
  • As knowledge continues to grow and evolve, access to what is needed is more important than what the learner currently possesses.

      Access is not enough. Prior knowledge and understanding is needed. Processing is needed. Evaluation of processing and outputs is needed. Feeding that back into the "system" is needed.

  • “The freshman year [as taught at traditional schools] should not exist,” Nelson says, suggesting that MOOCs can teach the basics. “Do your freshman year at home.”) Instead, Minerva’s first-year classes are designed to inculcate what Nelson calls “habits of mind” and “foundational concepts,” which are the basis for all sound systematic thought. In a science class, for example, students should develop a deep understanding of the need for controlled experiments. In a humanities class, they need to learn the classical techniques of rhetoric and develop basic persuasive skills. The curriculum then builds from that foundation.
  • What, he asks, does it mean to be educated?
  • methods will be tested against scientifically determined best practices
  • Subsidies, Nelson says, encourage universities to enroll even students who aren’t likely to thrive, and to raise tuition, since federal money is pegged to costs.

      I agree - context, and culture play a very important role. And this might change from corner to corner, it can change quickly, neighbours etc

  • Constructivist learning environments provide multiple representations of reality
  • Multiple representations avoid oversimplification and represent the complexity of the real world
  • Constructivist learning environments emphasize authentic tasks in a meaningful context rather than abstract instruction out of context.
  • Constructivist learning environments provide learning environments such as real-world settings or case-based learnin
  • Constructivist learning environments encourage thoughtful reflection on experience.
  • Constructivist learning environments support "collaborative construction of knowledge through social negotiation, not competition among learners for recognition.
  • Jonassen (1994)
  • There is no absolute knowledge, just our interpretation of it. The acquisition of knowledge therefore requires the individual to consider the information and - based on their past experiences, personal views, and cultural background - construct an interpretation of the information that is being presented to them.
  • Teaching styles based on this approach therefore mark a conscious effort to move from these ‘traditional, objectivist models didactic, memory-oriented transmission models’ (Cannella & Reiff, 1994) to a more student-centred approach.
  • Students ‘construct’ their own meaning by building on their previous knowledge and experience. New ideas and experiences are matched against existing knowledge, and the learner constructs new or adapted rules to make sense of the world
  • John Dewey (1933/1998) is often cited as the philosophical founder of this approach
  • while Vygotsky (1978) is the major theorist among the social constructivists.
  • Bruner (1990) and Piaget (1972) are considered the chief theorists among the cogn
  • Dewey
  • Piaget
  • John Dewey rejected the notion that schools should focus on repetitive, rote memorization & proposed a method of "directed living" – students would engage in real-world, practical workshops in which they would demonstrate their knowledge through creativity and collaboration
  • Piaget rejected the idea that learning was the passive assimilation of given knowledge. Instead, he proposed that learning is a dynamic process comprising successive stages of adaption to reality during which learners actively construct knowledge by creating and testing their own theories of the world.
  • A common misunderstanding regarding constructivism is that instructors should never tell students anything directly but, instead, should always allow them to construct knowledge for themselves. This is actually confusing a theory of pedagogy (teaching) with a theory of knowing. Constructivism assumes that all knowledge is constructed from the learner’s previous knowledge, regardless of how one is taught. Thus, even listening to a lecture involves active attempts to construct new knowledge.
  • social interaction lay at the root of good learning.
  • Bruner builds on the Socratic tradition of learning through dialogue, encouraging the learner to come to enlighten themselves through reflection
  • Careful curriculum design is essential so that one area builds upon the other. Learning must therefore be a process of discovery where learners build their own knowledge, with the active dialogue of teachers, building on their existing knowledge.
  • Social constructivism was developed by Vygotsky. He rejected the assumption made by Piaget that it was possible to separate learning from its social context.
    • robert morris
       
      On Vgotsky`s side here - I don`t think you can forget the role of "social learning", peer to peer learning and the role of social interaction.
  • The basic tenet of constructivism is that students learn by doing rather than observing.
  • By the 1980s the research of Dewey and Vygotsky had blended with Piaget's work in developmental psychology into the broad approach of constructivism
  • 1. Discovery Learning (Bruner) In discovery learning, the student is placed in problem solving situations where they are required to draw on past experiences and existing knowledge to discover facts, relationships, and new information. Students are more likely to retain knowledge attained by engaging real-world and contextualised problem-solving than by traditional transmission methods. Models that are based upon discovery learning model include: guided discovery, problem-based learning, simulation-based learning, case-based learning, and incidental learning.

Metacognition in Education - 14 views

  •  
    "Metacognition is widely accepted as "thinking about thinking", often inspired by the work in the 1970s of John Flavell, and its impact in educational circles cannot be denied. Indeed, John Hattie concluded that Metacognitive strategies have a positive impact score of D=0,69 - just outside the top ten of the most effective pedagogical strategies available to teachers - when sustained in the classroom. Additionally, the Educational Endowment Foundation advocate that Metacognition provides a 'high impact for low value', being easy to implement. Furthermore, Singapore's education system implemented Metacognition into their mathematics curriculum in the early 2000s, and their results speak for themselves."

Enhancing the power of our reflective practice - The Learner's Way - 18 views

  •  
    "We do not learn from experience... we learn from reflecting on experience." ― John Dewey These words by John Dewey point to a truth about learning that is often forgotten. Experience alone is not sufficient for true learning to occur; reflection is an essential part of the process and our failure to include time for this is why our learning often does not stick.

Photo Tampering Throughout History - 1 views

  • Photo Tampering Throughout History Photography lost its innocence many years ago. In as early as the 1860s, photographs were already being manipulated, only a few decades after Niepce created the first photograph in 1814. With the advent of high-resolution digital cameras, powerful personal computers and sophisticated photo-editing software, the manipulation of digital images is becoming more common. Here, I have collected some examples of tampering throughout history. To help contend with the implications of this tampering, we have developed a series of tools for detecting traces of tampering in digital images (contact me at Ma'at Consulting for more information about our services). circa 1860: This nearly iconic portrait of U.S. President Abraham Lincoln is a composite of Lincoln's head and the Southern politician John Calhoun's body. Putting the date of this image into context, note that the first permanent photographic image was created in 1826 and the Eastman Dry Plate Company (later to become Eastman Kodak) was created in 1881. circa 1865: In this photo by famed photographer Mathew Brady, General Sherman is seen posing with his Generals. General Francis P. Blair (far right) was added to the original photograph.

Anthropology Program at Kansas State University - Wesch - 0 views

  •  
    Dubbed "the explainer" by Wired magazine, Michael Wesch is a cultural anthropologist exploring the impact of new media on society and culture. After two years studying the impact of writing on a remote indigenous culture in the rain forest of Papua New Guinea, he has turned his attention to the effects of social media and digital technology on global society. His videos on culture, technology, education, and information have been viewed by millions, translated in over ten languages, and are frequently featured at international film festivals and major academic conferences worldwide. Wesch has won several major awards for his work, including a Wired Magazine Rave Award, the John Culkin Award for Outstanding Praxis in Media Ecology, and he was recently named an Emerging Explorer by National Geographic. He has also won several teaching awards, including the 2008 CASE/Carnegie U.S. Professor of the Year for Doctoral and Research Universities.

Aspirin stimulates insulin - 6 views

  • AbstractNormal subjects and patients with adult-onset diabetes received 10 gm. of aspirin in four days. On the fourth day, the fasting serum glucose and the glucose response to oral glucose were decreased in both groups. These changes were associated with increased levels of serum insulin and pancreatic glucagon, although the glucagon responses to oral glucose were unchanged. In the diabetic patients, aspirin therapy was followed by a decreased glucose response to I.V. glucose and by the appearance of an early insulin peak, which could not be demonstrated before treatment. Aspirin did not affect the I.V. glucose tolerance in normal subjects, although it did enhance the early insulin peak. A decrease in the fasting levels of free fatty acids was noted in both groups, whereas the fasting level of triglycerides decreased only in the diabetic patients. Cholesterolemia did not change in either group. A few preliminary observations indicate that, in normal subjects, ibuprofen and ketoprofen, two other presumed prostaglandin inhibitors, did not affect fasting glycemia, glucose tolerance, or the insulin response to glucose. No changes were noted after the administration of placebo.

I wonder if they did that to make sure they had a response and if there is a break point of some lower dose. I am on 325 once a day now. Been that high in the past for other things, lots of ringing in the ears when you get that high of a dose.

  • The therory is that it helps to regenerate the once turned off Beta cells, not over working the exiting ones. This is just one article I found, they are many, most of them concern Salsalate a drug used for arthritis. It works by lowering the inflammation of the liver and pancreas. Lowers IR, its a pretty interesting concept based largerly on inflammation of one muscles and organs. Originally Posted by jeanne wagner i know for heart health they recommend the baby 81 mg a day. I would think you wouldn't have a stomach lining left if you took that on a daily basis. Also just because it stimulates insulin doesn't mean it is a good thing. Sulfonyureas also overstimulate insulin and there is some thought they lead to beta cell burnout. I think it is better to find things like metformin that make you more sensitive to the insulin you naturally make.

    What qualifies as "text" is shifting every bit as much as our ever-changing definition of literacy. This resource expands our definition of texts, relying on John Greene's central principals that stories are: a). about communication, b). acts of empathy, c). opportunities to think critically and thoughtfully, thereby connecting us with each other, and d). springboards to learn more about others, our world around us, and ultimately, ourselves.

Rethinking the Way College Students Are Taught - 52 views

  • But here's the irony. "Mary is more likely to convince John than professor Mazur in front of the class," Mazur says. "She's only recently learned it and still has some feeling for the conceptual difficulties that she has whereas professor Mazur learned [the idea] such a long time ago that he can no longer understand why somebody has difficulty grasping it." That's the irony of becoming an expert in your field, Mazur says. "It becomes not easier to teach, it becomes harder to teach because you're unaware of the conceptual difficulties of a beginning learner."
  • To make sure his students are prepared, Mazur has set up a web-based monitoring system where everyone has to submit answers to questions about the reading prior to coming to class. The last question asks students to tell Mazur what confused them. He uses their answers to prepare a set of multiple-choice questions he uses during class.
  • Mazur begins class by giving a brief explanation of a concept he wants students to understand. Then he asks one of the multiple-choice questions. Students get a minute to think about the question on their own and then answer it using a mobile device that sends their answers to Mazur's laptop. Next, he asks the students to turn to the person sitting next to them and talk about the question. The class typically erupts in a cacophony of voices, as it did that first time he told students to talk to each other because he couldn't figure out what else to do. Once the students have discussed the question for a few minutes, Mazur instructs them to answer the question again.

      Why do we continue to do things the same way we always have and expect different results from what we have always gotten?

      How true this statement is!  If students want to learn, they are going to learn in spite of who the teacher is or what the teacher does - no teacher is really needed!
  • So Mazur gave what he thought was a thorough and thoughtful explanation of the concept. He went slowly, putting all kinds of helpful diagrams up on the board. "I thought I'd nailed it," he says. "I thought it was the best explanation one could possibly give of this question." Mazur triumphantly turned around. "Any questions?" he asked. The students just stared at him. "Nobody raised their hand and said, well but what if this and what if that, simply because they were so confused they couldn't," he says. "I didn't know what to do. But I knew one thing. I knew that 50 percent of the students had given the right answer."

      How many times have we done this when we are providing direct instructions to students and then felt frustration when we assess what they know?  ARGH!

Hanging Out, Messing Around, and Geeking Out: Kids Living and Learning with New Media (... - 32 views

  •  
    "Hanging Out, Messing Around, and Geeking Out fills this gap, reporting on an ambitious three-year ethnographic investigation into how young people are living and learning with new media in varied settings-at home, in after school programs, and in online spaces. By focusing on media practices in the everyday contexts of family and peer interaction, the book views the relationship of youth and new media not simply in terms of technology trends but situated within the broader structural conditions of childhood and the negotiations with adults that frame the experience of youth in the United States. Integrating twenty-three different case studies-which include Harry Potter podcasting, video-game playing, music-sharing, and online romantic breakups-in a unique collaborative authorship style, Hanging Out, Messing Around, and Geeking Out is distinctive for its combination of in-depth description of specific group dynamics with conceptual analysis."

John Lundberg: Should Students Be Memorizing Poetry? - 2 views

  • Memorizing a poem, in a strange sort of way, gives that poem access to you more than you're giving yourself access to it.
  • A poem can be a sort of anchor in the drift of the world. Whether it serves as a bit of wisdom that helps keep you centered, or, in my case, as a feeling, a moment of beauty and power that helps keep my other feelings in perspective.
  • Do you agree?

Educational Leadership:Feedback for Learning:Seven Keys to Effective Feedback - 87 views

  • Whether the feedback was in the observable effects or from other people, in every case the information received was not advice, nor was the performance evaluated. No one told me as a performer what to do differently or how "good" or "bad" my results were. (You might think that the reader of my writing was judging my work, but look at the words used again: She simply played back the effect my writing had on her as a reader.) Nor did any of the three people tell me what to do (which is what many people erroneously think feedback is—advice). Guidance would be premature; I first need to receive feedback on what I did or didn't do that would warrant such advice.
  • Decades of education research support the idea that by teaching less and providing more feedback, we can produce greater learning (see Bransford, Brown, & Cocking, 2000; Hattie, 2008; Marzano, Pickering, & Pollock, 2001).

  • But There's No Time!"
  • remember that feedback does not need to come only from the teacher, or even from people at all. Technology is one powerful tool—part of the power of computer-assisted learning is unlimited, timely feedback and opportunities to use it.
  • learners are often unclear about the specific goal of a task or lesson, so it is crucial to remind them about the goal and the criteria by which they should self-assess
  • I recommend that all teachers videotape their own classes at least once a month. It was a transformative experience for me when I did it as a beginning teacher.
  • research shows that less teaching plus more feedback is the key to achieving greater learning.
  • Even if feedback is specific and accurate in the eyes of experts or bystanders, it is not of much value if the user cannot understand it or is overwhelmed by it.
  • Adjusting our performance depends on not only receiving feedback but also having opportunities to use it.
  • Clearly, performers can only adjust their performance successfully if the information fed back to them is stable, accurate, and trustworthy. In education, that means teachers have to be on the same page about what high-quality work is. Teachers need to look at student work together, becoming more consistent over time and formalizing their judgments in highly descriptive rubrics supported by anchor products and performances.
  • Score student work in the fall and winter against spring standards, use more pre-and post-assessments to measure progress toward these standards, and do the item analysis to note what each student needs to work on for better future performance.
  • Effective supervisors and coaches work hard to carefully observe and comment on what they observed, based on a clear statement of goals. That's why I always ask when visiting a class, "What would you like me to look for and perhaps count?"
  • . Less teaching, more feedback. Less feedback that comes only from you, and more tangible feedback designed into the performance itself.
  • how we are doing in our efforts to reach a goal.
  • get another opportunity to receive and learn from the feedback.
  • computer games
  • quickly adapt
  • ack, do you have some ideas about how to improve?" This approach will build greater autono
  • ck, do you have some ideas about how to improve?" This approach will build greater autono
  •  
    Wiggins Advice, evaluation, grades-none of these provide the descriptive information that students need to reach their goals. What is true feedback-and how can it improve learning? Who would dispute the idea that feedback is a good thing? Both common sense and research make it clear: Formative assessment, consisting of lots of feedback and opportunities to use that feedback, enhances performance and achievement. Yet even John Hattie (2008), whose decades of research revealed that feedback was among the most powerful influences on achievement, acknowledges that he has "struggled to understand the concept" (p. 173). And many writings on the subject don't even attempt to define the term. To improve formative assessment practices among both teachers and assessment designers, we need to look more closely at just what feedback is-and isn't.
