Why I Like Prezi - 0 views

  •  
    Why I Like Prezi In my life, I have given a *lot* of presentations. In high school, they were presentations on group projects. In university, they were presentations on research projects. At Google, they're presentations on how to use our APIs. When I first started giving presentations, I used Powerpoint, like everyone else. But I kept thinking there must be a better way, and I experimented with other options - flash interfaces, interactive Javascript apps. Then I discovered Prezi, and it has become my presentation tool of choice. Prezi is an online tool for creating presentations - but it's not just a Powerpoint clone, like the Zoho or Google offering. When you first create a Prezi, you're greeted with a blank canvas and a small toolbox. You can write text, insert images, and draw arrows. You can draw frames (visible or hidden) around bits of content, and then you can define a path from one frame to the next frame. That path is your presentation. It's like being able to draw your thoughts on a whiteboard, and then instructing a camera where to go and what to zoom into. It's a simple idea, but I love it. Here's why: It forces me to "shape" my presentation. A slide deck is always linear in form, with no obvious structure of ideas inside of it. Each of my Prezis has a structure, and each structure is different. The structure is visual, but it supports a conceptual structure. One structure might be 3 main ideas, with rows of ideas for each one. Another might be 1 main idea, with a circular branching of subideas. Having a structure helps me to have more of a point to my presentations, and to realize the core ideas of them. It makes it easy to go from brainstorming stage to presentation stage, all in the same tool. I can write a bunch of thoughts, insert some images, and easily move them around, cluster them, re-order them, etc. I can figure out the structure of my presentation by looking at what I have laid out, and seeing how they fit together. Some people do this

Using Groups Effectively: 10 Principles » Edurati Review - 50 views

  •  
    "Conversation is key . Sawyer succinctly explains this principle: "Conversation leads to flow, and flow leads to creativity." When having students work in groups, consider what will spark rich conversation. The original researcher on flow, Mihaly Csikszentmihalyi, found that rich conversation precedes and ignites flow more than any other activity.1 Tasks that require (or force) interaction lead to richer collaborative conceptualization. Set a clear but open-ended goal . Groups produce the richest ideas when they have a goal that will focus their interaction but also has fluid enough boundaries to allow for creativity. This is a challenge we often overlook. As teachers, we often have an idea of what a group's final product should look like (or sound like, or…). If we put students into groups to produce a predetermined outcome, we prevent creative thinking from finding an entry point. Try not announcing time limits. As teachers we often use a time limit as a "motivator" that we hope will keep group work focused. In reality, this may be a major detractor from quality group work. Deadlines, according to Sawyer, tend to impede flow and produce lower quality results. Groups produce their best work in low-pressure situations. Without a need to "keep one eye on the clock," the group's focus can be fully given to the task. Do not appoint a group "leader." In research studies, supervisors, or group leaders, tend to subvert flow unless they participate as an equal, listening and allowing the group's thoughts and decisions to guide the interaction. Keep it small. Groups with the minimum number of members that are needed to accomplish a task are more efficient and effective. Consider weaving together individual and group work. For additive tasks-tasks in whicha group is expectedtoproduce a list, adding one idea to another-research suggests that better results develop

  • AssessmentThere were four components of the assessment process for this test case of the Networked Student Model: (1) Ongoing performance assessment in the form of weekly assignments to facilitate the construction and maintenance of the personal learning environment, (2) rubric-based assessment of the personal learning environment at the end of the project, (3) written essay, and (4) multimedia synthesis of topic content. Points were earned for meeting the following requirements: Identify ten reliable resources and post to social bookmarking account. At least three new resources should be added each week. Subscribe and respond to at least 3 new blogs each week. Follow these blogs and news alerts using the reader. Subscribe to and listen to at least two podcasts (if available). Respectfully contact and request a video conference from a subject matter expert recognised in the field. Maintain daily notes and highlight resources as needed in digital notebook. Post at least a one-paragraph reflection in personal blog each day. At the end of the project, the personal learning environment was assessed with a rubric that encompassed each of the items listed above. The student's ability to synthesise the research was further evaluated with a reflective essay. Writing shapes thinking (Langer & Applebee, 1987), and the essay requirement was one more avenue through which the students demonstrated higher order learning. The personal blog provided an opportunity for regular reflection during the course of the project. The essay was the culmination of the reflections along with a thoughtful synthesis of the learning experience. Students were instructed to articulate what was learned about the selected topic and why others should care or be concerned. The essay provided an overview of everything learned about the contemporary issue. It was well organised, detailed, and long enough to serve as a resource for others who wished to learn from the work. As part of a final exam, the students were required to access the final projects of their classmates and reflect on what they learned from this exposure. The purpose of this activity was to give the students an additional opportunity to share and learn from each other. Creativity is considered a key 21st century skill (Partnership for 21st Century Skills, 2009). A number of emerging web applications support the academic creative process. Students in this project used web tools to combine text, video, audio, and photographs to teach the research topics to others. The final multimedia project was posted or embedded on the student's personal wiki page. Analysis and assessment of student work was facilitated by the very technologies in use by the students. In order to follow their progress, the teacher simply subscribed to student social bookmarking accounts, readers, and blogs. Clicking through daily contributions was relatively quick and efficient.

Julia Kristeva - 5 views

  • Theories of the body are particularly important for feminists because historically (in the humanities) the body has been associated with the feminine, the female, or woman, and denigrated as weak, immoral, unclean, or decaying.
    • Christopher Williams
       
      Feminism and post-structuralism operate in binaries: good/evil, truth/lie, love/hate, man/not man(woman)
  • Kristeva emphasizes the maternal function and its importance in the development of subjectivity and access to culture and language. While Freud and Lacan maintain that the child enters the social by virtue of the paternal function, specifically paternal threats of castration, Kristeva asks why, if our only motivation for entering the social is fear, more of us aren't psychotic?
  • Kristeva argues that there are three phases of feminism. She rejects the first phase because it seeks universal equality and overlooks sexual differences. She implicitly criticizes Simone de Beauvoir and the rejection of motherhood; rather than reject motherhood Kristeva insists that we need a new discourse of maternity.

    "As part of Edutopia's summer professional development experiences, we are starting a Web Tools Collective to explore and learn with other teachers from around the world. We plan to "study" a variety of web tools and resources, and identify ways that they can be used in the classroom. The Web Tools Collective is a flexible, open-learning experience. We will provide a learning space (Edutopia blogs and groups) and a loose structure for exploration. You are welcome to jump in and out as your schedule and interest allows. You can post daily, weekly, just once or twice, or you can even just lurk. "

Memory - Wikipedia, the free encyclopedia - 0 views

  • Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).
  • Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).
  • Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

  • Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
  • At the Center for Cognitive Science at Ohio State University, researchers have found that memory accuracy of adults is hurt by the fact that they know more, and have more experience than children, and tend to apply all this knowledge when learning new information. The findings appeared in the August 2004 edition of the journal Psychological Science.
  • Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information[59] and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French – this phenomenon is known as positive transfer.[60]
  • Methods to optimize memorization[edit] Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming which is intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.[72]

Six Scaffolding Strategies to Use with Your Students | Edutopia - 13 views

  •  
    "Let's start by agreeing that scaffolding a lesson and differentiating instruction are two different things. Scaffolding is breaking up the learning into chunks and then providing a tool, or structure, with each chunk. When scaffolding reading, for example, you might preview the text and discuss key vocabulary, or chunk the text and read and discuss as you go. With differentiation, you may give a child an entirely different piece of text to read, you might shorten the text or alter it, and you may modify the writing assignment that follows."

      This is a neat way to start a writing class with the creating plot ideas....
  • One of the goals I ask teachers to set after my training is to find new ways to push students to analyze and evaluate as they learn to write.
  • As part of my teacher workshop on the writing process, we investigate multiple uses of student samples. One of my favorite techniques involves having student compare and contrast finished pieces of writing. During both pre-writing and and revision, this push for deeper student thinking both educates and inspires your students.

  • The handout has student writers analyze two fifth graders' published writing with a compare and contrast Venn diagram.
  • Revision is hard, and most teachers recognize it as an area of deficiency; the truth is, a lot of really great writing teachers I know still freely admit that revision is where they struggle the most.
  • revision shouldn't be the first of the seven elements to work on
  • When students like what they've written in rough draft form, they're ready to move to revision. My other six elements aim at helping students increase their pre-writing time so they both like and see more potential in their rough drafts
  • I believe in the power of collaboration and study teams,
  • Professional development research clearly cites the study team model as the most effective way to have learners not only understand new ideas but also implement them enough times so they become regular tools in a teacher's classroom.
  • Below, find three examples created by study teams during past workshops. I use them as models/exemplars when I set the study teams off to work.

  • I also use variations of these Post-its during my Critical Thinking Using the Writing Traits Workshop.
  • By far, the best success I've ever had while teaching revision was the one I experienced with the revision Post-its I created for my students
  • During my teacher workshop on the writing process, we practice with tools like the Revision Sprint (at right), which I designed to push students to use analysis and evaluation skills as they looked at their own drafts
  • I used to throw my kids into writing response groups way too fast. They weren't ready to provide critical thought for one another
  • The most important trick learned was this: be a writer too. During my first five years of teaching, I had assigned a lot of writing but never once had I written something I intended to show my students.

If you can't do that, then I'll throw you a challenge that was thrown once at me, and completing the challenge helped me become a smarter designer of graphic organizers. The challenge came in two parts: 1) learn how to use tables and text boxes in Microsoft Word; 2) for practice, design a graphic organizer that would help students be successfully with the following trait-based skills:
  • "It was the best of times, it was the worst of times, etc," which is an interesting structure that students can borrow from to write about other topics, be they fiction or non-fiction.
  • Asking students to create daily journals from the perspective of other animals or even inanimate objects is a great way to borrow this book's idea.

  • Here are seven skills I can easily list for the organization trait. Organization is: 1) using a strong lead or hook, 2) using a variety of transition words correctly, 3) paragraphing correctly, 4) pacing the writing, 5) sequencing events/ideas logically, 6) concluding the writing in a satisfying way, 7) titling the writing interestingly and so that the title stands for the whole idea. Over the years, I have developed or found and adapted mini-lessons that have students practice these skills during my "Organization Month."
  • Now, let's talk differentiation:
  • The problem with focusing students on a product--instead of the writing process--is that the majority of the instructional time is spent teaching students to adhere to a formula.
  • the goal of writing instruction absolutely should be the helping students practice the three Bloom's levels above apply: analyze, evaluate, and create.
  • Click here to access the PowerPoint I use during the goal-setting portion of my workshop.
  • Improving one's ability to teach writing to all students is a long-term professional development goal; sticking with it requires diligence, and it requires having a more specific goal than "I want to improve writing
  • "Trying to get better at all seven elements at once doesn't work;
  • strive to make my workshops more about "make and take,
  • Robert Marzano's research convinced me years ago of the importance of having learners set personal goals as they learn to take responsibility for their own learning.

Göbekli Tepe - Pictures, More From National Geographic Magazine - 67 views

  • The Birth of ReligionWe used to think agriculture gave rise to cities and later to writing, art, and religion. Now the world’s oldest temple suggests the urge to worship sparked civilization.
  • Before them are dozens of massive stone pillars arranged into a set of rings, one mashed up against the next. Known as Göbekli Tepe (pronounced Guh-behk-LEE TEH-peh), the site is vaguely reminiscent of Stonehenge, except that Göbekli Tepe was built much earlier and is made not from roughly hewn blocks but from cleanly carved limestone pillars splashed with bas-reliefs of animals—a cavalcade of gazelles, snakes, foxes, scorpions, and ferocious wild boars. The assemblage was built some 11,600 years ago, seven millennia before the Great Pyramid of Giza. It contains the oldest known temple. Indeed, Göbekli Tepe is the oldest known example of monumental architecture—the first structure human beings put together that was bigger and more complicated than a hut. When these pillars were erected, so far as we know, nothing of comparable scale existed in the world.
  • At the time of Göbekli Tepe's construction much of the human race lived in small nomadic bands that survived by foraging for plants and hunting wild animals. Construction of the site would have required more people coming together in one place than had likely occurred before. Amazingly, the temple's builders were able to cut, shape, and transport 16-ton stones hundreds of feet despite having no wheels or beasts of burden. The pilgrims who came to Göbekli Tepe lived in a world without writing, metal, or pottery; to those approaching the temple from below, its pillars must have loomed overhead like rigid giants, the animals on the stones shivering in the firelight—emissaries from a spiritual world that the human mind may have only begun to envision.
  • ...15 more annotations...
  • Archaeologists are still excavating Göbekli Tepe and debating its meaning. What they do know is that the site is the most significant in a volley of unexpected findings that have overturned earlier ideas about our species' deep past. Just 20 years ago most researchers believed they knew the time, place, and rough sequence of the Neolithic Revolution—the critical transition that resulted in the birth of agriculture, taking Homo sapiens from scattered groups of hunter-gatherers to farming villages and from there to technologically sophisticated societies with great temples and towers and kings and priests who directed the labor of their subjects and recorded their feats in written form. But in recent years multiple new discoveries, Göbekli Tepe preeminent among them, have begun forcing archaeologists to reconsider. At first the Neolithic Revolution was viewed as a single event—a sudden flash of genius—that occurred in a single location, Mesopotamia, between the Tigris and Euphrates Rivers in what is now southern Iraq, then spread to India, Europe, and beyond. Most archaeologists believed this sudden blossoming of civilization was driven largely by environmental changes: a gradual warming as the Ice Age ended that allowed some people to begin cultivating plants and herding animals in abundance. The new research suggests that the "revolution" was actually carried out by many hands across a huge area and over thousands of years. And it may have been driven not by the environment but by something else entirely.

  • Göbekli Tepe may be the first of all of them, the beginning of a pattern. What it suggests, at least to the archaeologists working there, is that the human sense of the sacred—and the human love of a good spectacle—may have given rise to civilization itself.
  • n the 1960s archaeologists from the University of Chicago had surveyed the region and concluded that Göbekli Tepe was of little interest. Disturbance was evident at the top of the hill, but they attributed it to the activities of a Byzantine-era military outpo
  • To Schmidt, the T-shaped pillars are stylized human beings, an idea bolstered by the carved arms that angle from the "shoulders" of some pillars, hands reaching toward their loincloth-draped bellies. The stones face the center of the circle—as at "a meeting or dance," Schmidt says—a representation, perhaps, of a religious ritual. As for the prancing, leaping animals on the figures, he noted that they are mostly deadly creatures: stinging scorpions, charging boars, ferocious lions. The figures represented by the pillars may be guarded by them, or appeasing them, or incorporating them as totems.
  • nches below the surface the team struck an elaborately fashioned stone. Then another, and another—a ring of standing pillars.
  • Geomagnetic surveys in 2003 revealed at least 20 rings piled together, higgledy-piggledy, under the earth.
  • he pillars were big—the tallest are 18 feet in height and weigh 16 tons. Swarming over their surfaces was a menagerie of animal bas-reliefs, each in a different style, some roughly rendered, a few as refined and symbolic as Byzantine art.
  • The circles follow a common design. All are made from limestone pillars shaped like giant spikes or capital T's.
  • They hadn't yet mastered engineering." Knoll speculated that the pillars may have been propped up, perhaps by wooden posts.
  • Within minutes of getting there," Schmidt says, he realized that he was looking at a place where scores or even hundreds of people had worked in millennia past.
  • Puzzle piled upon puzzle as the excavation continued. For reasons yet unknown, the rings at Göbekli Tepe seem to have regularly lost their power, or at least their charm. Every few decades people buried the pillars and put up new stones—a second, smaller ring, inside the first.
  • he site may have been built, filled in, and built again for centuries.
  • Bewilderingly, the people at Göbekli Tepe got steadily worse at temple building.
  • Finally the effort seems to have petered out altogether by 8200 B.C. Göbekli Tepe was all fall and no rise.
