diigo education review

shared by Maggie Tsai on 24 Oct 08 - Cached
  • What I like is that Diggo not only lets you easily save items, it lets you highlight the "good parts" so that when you go back to the article you can easily find them. That turned out to be a real asset when I was working on my part of the JACC Norcal keynote a couple weeks ago.It's been a real pressure cooker of a semester, so I had very little time to put my JACC presentation together. However, I'd been bookmarking, highlighting and saving relevant blog posts and articles into my JACC list on Diigo (yes, you can categorize what you save) for weeks. So when I finally sat down to create a presentation, I had everything I needed at my fingertips. I was able to put it all together in a day. (By the way, you can view that presentation, Journalism in the Starbucks Era, on SlideShare, another great online tool.)But after downloading a Diigo update this morning, I realized I'm just scratching the surface of what you can do with Diigo. For example, my previous blog post on Greenspan's sudden epiphany...well, I posted it direct from Diigo while reading and bookmarking the article. Pretty cool, huh?When I ran through Diigo's "how-to" overview this morning, I found several other things I didn't know. In addition to using the one-click "Send to Blog" feature, you can also use Diigo's "send" feature to:send annotated and highlighted pages by emailpost to other websites such as twitter, facebook, delicious, etc.Cool! I'm using it for a tweet next.
  • But what really caught my attention was the idea of using Diigo as a hub for group research projects. You can set up a group Diigo account to share bookmarks, and make it public, private or semi-private. This has real potential for students working on group projects, especially since Diigo's "sticky note" feature also lets you add comments to the material you save, in addition to highlighting key passages.OK, I'm sold! I'm going to start demo-ing Diigo for my students.

Psilocybin (magic mushrooms) - 0 views

  • The biosinthetic path that allow Psilocybin to be produced by mushrooms is as follow:
  • The several analogyes with triptophan aminoacid, with whom psilocybin has common origines are probably at the base of psilocybin ability to induced psychedelich alteration on humans.
  • Amino acids, including tryptophan, act as building blocks in protein biosynthesis. In addition, tryptophan functions as a biochemical precursor for many compounds like serotonin Serotonin (a neurotransmitter), synthesized via tryptophan hydroxylase. Serotonin, in turn, can be converted to melatonin (a neurohormone), via N-acetyltransferase and 5-hydroxyindole-O-methyltransferase activities
  • ...15 more annotations...
  • it's been noticed that psilocyn can indirectly raise dopamine concentration withing the basal ganglia.
  • Almost 50% of oral psilocybin is absorbed by stomach and gut; from here is lead to liver, where it's converted in psilocin, pharmacologically active form, that can furtherly be glucoronated and escreted with urine or converted in other psilocinics metabolites.
  • In rats, the median lethal dose (LD50) when administered orally is 280 milligrams per kilogram (mg/kg), approximately one and a half times that of caffeine. When administered intravenously in rabbits, psilocybin's LD50 is approximately 12.5 mg/kg
  • traces of the compund can be detected in unine even after 7 days.
  • Clinical studies show that psilocin concentrations in the plasma of adults average about 8 µg/liter within 2 hours after ingestion of a single 15 mg oral psilocybin dose; psychological effects occur with a blood plasma concentration of 4–6 µg/liter. Psilocybin is about 100 times less potent than LSD on a weight per weight basis, and the physiological effects last about half as long.
  • Within 24 hours from administration 65% of the alucinogen is escreted by urine, while another 15-20% is excreted by bile and feces.
  • Monoamine oxidase inhibitors (MAOI) have been known to prolong and enhance the effects of psilocybin. Alcohol consumption may enhance the effects of psilocybin, because acetaldehyde, one of the primary breakdown metabolites of consumed alcohol, reacts with biogenic amines present in the body to produce MAOIs related to tetrahydroisoquinoline and β-carboline. Tobacco smokers can also experience more powerful effects with psilocybin, because tobacco smoke exposure decreases levels of MAO in the brain and peripheral organs.
  • This could lead to a lower usage o f glucose, but the same study admitted an increase glucose usage by the whole brain cell, meaning a differente use of this sugar while the drug is having effects.
  • use of MRI (functional magnetic resounance) showed that the decresed blood flow associate with decreasing in neural activity. A simple explanation for this unexpected situation could be the serotoning agonist action of psilocybin, action that seems to be focused more on 5-HT receptors than on 5-HT2A.
  • psilocibyn is able to act as a 5-HT agonist binding directly its receptors.
  • augmented glucose consumption in several brain regions; this lead to the conclusion that psilocybin is some way able to modify the physiological glucosal metabolic rate of our body
  • The strong inibition of the PCC is now thought to be most significant action of psilocybin on neural disaccoppiation
    • Kenuvis Romero
      Kenuvis Romero on 23 Jun 13
       
      Lower brain glucose metabolism is linked with increased capacity for working memory.
  • Psilocybin comprises approximately 1% of the weight of Psilocybe cubensis mushrooms, and so nearly 1.7 kilograms (3.7 lb) of dried mushrooms, or 17 kilograms (37 lb) of fresh mushrooms, would be required for a 60-kilogram (130 lb) person to reach the 280 mg/kg LD50 value.
  • psilocybin can cause anxiety and increased heart rate and BP which is very counter- productive for someone on metoprolol and micardis.
  • propose the possibility to use psilocybin as a palliative therapy for terminal illness like cancer but also as a real antidepressive active principle available for the family of the patient. The rational is foundable in the fact that we usually administer SSRI as antidepressive agents, so psilocibyn sholud be useful in this purpose for its selective agonist action on 5-HT2A receptors

professional_development

shared by Daryl Bambic on 09 Jun 10 - Cached
  • 1. Be the change. Leaders of professional development seem to forget that they’re actually teaching, and that part of teaching is modeling the activity you hope to see adopted. A session devoted to equipping teachers to implement more collaborative learning that is presented via “death by PowerPoint” is an oxymoron, a term originating from a Greek word appropriately meaning “pointedly foolish.” As one teacher recently expressed it, “Why does the worst teaching often happen in sessions on how to improve teaching?” Why, indeed? Modeling is a powerful teaching technique. In addition to communicating that the suggested new approach promotes learning, demonstration taps into some of the brain’s natural learning systems: This may be because demonstration actually encourages the brain to engage. Specialized neurons known as mirror neurons make practicing “in the head” possible…When a teacher repeatedly performs a sequence of steps, her students’ mirror neurons may enable their own preliminary practice of the same steps. In other words, as a teacher demonstrates a skill, students mentally rehearse it.1
  • Though we’ve been invited to lead professional development, we do not have all the answers. Professional development involves merging new research findings with current personnel—i.e., bringing ideas and people together. One way I’ve tried to do more of this recently is to ask teachers if any of them have tried something similar to a new approach I’ve explained. If any have, I invite them to share their experience. This invites elaboration, a critical cognitive process for constructing understanding. If the teacher’s experience was positive, we discuss why the approach was successful. If the teacher’s experience was frustrating, we often find together the reason for it and develop a plan for structuring it better the next time. This give-and-take values everyone, respects the experience present in the session, and allows the leader to be a colleague rather than an aloof expert.
  • 2. Listen. I have a tendency to get preoccupied with my preparation and forget that I’ll actually have people in the professional development session. Not just people but colleagues!
  • ...1 more annotation...
  • 3. Follow up. I’ve written previously about the importance of coaching and the characteristics of an effective coach. A one-time information flood is ineffective, no matter how engaging the session’s leader may be. Teachers need support as they begin to implement new ideas, methods, and approaches. Note that support, not judgement, is needed. Showing up with an evaluation form is a certain way to kill any benefit professional development might yield. Teachers are learners, and we need the time and space to try, to reflect, to try again, to get helpful feedback, and to truly master implementation. We need the opportunity to learn. Coaching provides this opportunity, along with the encouragement and feedback necessary for success.

    Physics Games.net, as the name implies, is a website of games based on simple physics concepts. Physic Games offers dozens of games based on a physics concept or two. Each game can be played directly on the Physics Games website or embedded into your blog or website. The one downfall of the site is that before each game starts there is a short commercial. I checked out a few different games, and I did not see any advertising that would be unacceptable in a public school classroom.

shared by Ed Webb on 15 Mar 10 - Cached
  • Students in Howard Rheingold’s journalism class at Stanford recently teamed up with NewsTrust, a nonprofit Web site that enables people to review and rate news articles for their level of quality, in a search for lousy journalism.
  • the News Hunt is a way of getting young journalists to critically examine the work of professionals. For Rheingold, an influential writer and thinker about the online world and the man credited with coining the phrase “virtual community,” it’s all about teaching them “crap detection.”
  • last year Rheingold wrote an important essay about the topic for the San Francisco Chronicle’s Web site
  • ...3 more annotations...
  • What’s at stake is no less than the quality of the information available in our society, and our collective ability to evaluate its accuracy and value. “Are we going to have a world filled with people who pass along urban legends and hoaxes?” Rheingold said, “or are people going to educate themselves about these tools [for crap detection] so we will have collective intelligence instead of misinformation, spam, urban legends, and hoaxes?”
  • I previously called fact-checking “one of the great American pastimes of the Internet age.” But, as Rheingold noted, the opposite is also true: the manufacture and promotion of bullshit is endemic. One couldn’t exist without the other. That makes Rheingold’s essay, his recent experiment with NewsTrust, and his wiki of online critical-thinking tools” essential reading for journalists. (He’s also writing a book about this topic.)
  • I believe if we want kids to succeed online, the biggest danger is not porn or predators—the biggest danger is them not being able to distinguish truth from carefully manufactured misinformation or bullshit

  • if a teacher can do a few basic computer skills (format in MS Word, copy and paste, attach a document to an email or upload a photo, and perhaps add a hyperlink) they should be able to transfer that knowledge across various internet programs.
  • Teachers sometimes express surprise when a student can’t write a response to a question that is virtually the same as one they answered the day before simply because it is worded differently. Yet teachers can’t apply what they know about Facebook (or shutterfly, gmail, youtube, etc.) to use edmodo or a wiki? I’m not saying they should be able to master a new program immediately – like anything new it takes time, but they should have the flexibility of thinking to apply what they already know. If teachers can’t transfer their knowledge, how are they going to teach students to do so?
  • Learners are no longer dependent on learning directly from an expert, the information is literally at their fingertips, they just need to know how to access it. And most important, learners of all ages need to be the drivers of their learning. Just like our students, teachers need to seek answers through active exploration. Again, if we are not independent learners, how can we expect our students to be?
  • ...2 more annotations...
  • Dependent on PD
  • Besides the lack of time and/or motivation, I’m beginning to wonder if teachers really know how to learn new skills independently. We come from a system of education where everything was fed to us. As a student (even through my master’s degree), if I was told I needed to learn something there was a clear process I had to go through to learn it; sign up (and pay) for the right course with the available expert, buy some textbooks, go to class, follow directions, and collect my credits to show that I had learned it. Most PD follows a similar process (although greatly abbreviated). So that is the paradigm that teachers have for their own learning – they feel that they need to be taught something in order to learn it. I’m not sure that they know there is now another way to learn, especially where learning about technology is concerned. But how would they know this new way of learning if it’s rarely been modeled for them? And if this is how they view their own learning, can we really expect them to teach students how to be independent learners?

    I'm more interested in having our students make a mark than get a mark, and so are they. So, lets be genuine with them. Push them to create great stuff about important ideas and students will not only rise to the challenge, they will be able to articulate what they have learned and why it matters. Do this, and don't cheapen it with a mark. Share your descriptive feedback, offer a genuine response. Let them know that when it comes time to write the report card you'll turn the great things they have created into a grade and all they have to do is keep creating things~the wonderful thing about people is we actually do great things when we are given the chance, a purpose, feedback and an audience. After all, look at all of us bloggers.

  • Thinking about solar?
  • Green Ray Solar this week is expected to announce UL certification for a solar panel that puts out alternating current, rather than direct current as most solar photovoltaic panels do today. AC panels can be simpler to install and wire together than traditional panels, which makes a piecemeal approach easier,
  • Traditionally, solar panels are tied into a device called an inverter, which converts the direct current from panels into household alternating current. Strung together, several panels produce enough voltage to run an inverter which, sized for a rooftop array, is roughly as big as a computer monitor.
  • ...2 more annotations...
  • A microinverter brings that DC-to-AC function onto each individual panel. Proponents say the technology simplifies installation and improves panel performance.
  • For example, shading on one panel will not affect the output of other panels connected to it, as happens with panels connected to a centralized inverter.

    To ensure reflective practice is more than an activity added to our schedule, we need to take a reflective stance. Too often, reflection becomes the thing we do at the end of a task or the end of the day. We look back and contemplate what was, and with that in mind, we look forward to what we might do differently next time. It is in this way a very reactionary process. By all means, this form of reflection has its place, and it can be a powerful strategy to deploy as we seek to learn from experience. If we value reflective practice, we will be sure to set aside time for this form of reflection on a routine basis. By engaging in reflection habitually, we ensure that it is a routine part of our day. But adopting a reflective stance can make this more powerful.
