Real Life Maths: Potions Lesson by @PrimaryLessons - 41 views

  •  
    "This is a really good way of testing out practical measuring skills in Maths lessons. I always teach 'measuring' by incorporating a Harry Potter themed Potions lesson. Pupils follow potion recipes to create potions from the Harry Potter universe, e.g. Polyjuice Potion or Skele-gro. I have a mixture of powders (cornflour), plants (herbs) and potions (water with food colouring). I then have pipettes, a range of different containers with different scales for measuring liquids, scales for measuring the plants and powders, in addition to gloves for handling the 'poisonous' plants, a pestle and mortar for the plants and stopwatches for timing."

CHRISTIE HEMM KLOK/WIRED SO YOU'RE A parent, thinking about sending your 7-year-old to this rogue startup of a school you heard about from your friend's neighbor's sister. It's prospective parent information day, and you make the trek to San Francisco's South of Market neighborhood. You walk up to the second floor of the school, file into a glass-walled conference room overlooking a classroom, and take a seat alongside dozens of other parents who, like you, feel that public schools-with their endless bubble-filled tests, 38-kid classrooms, and antiquated approach to learning-just aren't cutting it. At the same time, you're thinking: this school is kind of weird. On one side of the glass is a cheery little scene, with two teachers leading two different middle school lessons on opposite ends of the room. But on the other side is something altogether unusual: an airy and open office with vaulted ceilings, sunlight streaming onto low-slung couches, and rows of hoodie-wearing employees typing away on their computers while munching on free snacks from the kitchen. And while you can't quite be sure, you think that might be a robot on wheels roaming about. Then there's the guy who's standing at the front of the conference room, the school's founder. Dressed in the San Francisco standard issue t-shirt and jeans, he's unlike any school administrator you've ever met. But the more he talks about how this school uses technology to enhance and individualize education, the more you start to like what he has to say. And so, if you are truly fed up with the school stat

Truly random numbers - 41 views

  • At a quantum scale, the motion of electrons and protons is completely and genuinely random, since it doesn’t follow a clear path of cause and effect. You basically have no idea what’s going to happen. If you can measure this somehow, than you’ve got yourself an absolutely random value.
  • “If you want to defeat an adversary who is trying to hack into your system, basically you need large quantities of random numbers,”  Sussman said.
  • “…a truly random number generator will provide impenetrable encryption for communications — be they military transmissions, secure banking, or online purchasing — that underpin the modern connected world.”

The light comes and goes through the diamond, however when it exists it’s changed, since it has to pass through quantum vacuum fluctuations, the microscopic flickering of the amount of energy in a point in space. Scientists can measure these pulses of light that emerge from the experimental set-up, measurements which are the truly random.

Final Report: Friendship | DIGITAL YOUTH RESEARCH - 1 views

  • Social relations—not simply physical space—structure the social worlds of youth.
    • Laura Doto
       
      A critical conclusion to be realized that can inform our assumptions as educators.
  • When teens are involved in friendship-driven practices, online and offline are not separate worlds—they are simply different settings in which to gather with friends and peers
  • these dynamics reinforce existing friendship patterns as well as constitute new kinds of social arrangements.
  • ...43 more annotations...
  • Homophily describes the likelihood that people connect to others who share their interests and identity.
  • One survey of Israeli teens suggests that those who develop friendships online tend toward less homogenous connections than teens who do not build such connections
  • Teens frequently use social media as additional channels of communication to get to know classmates and turn acquaintances into friendships.
  • Some teens—especially marginalized and ostracized ones—often relish the opportunity to find connections beyond their schools. Teens who are driven by specific interests that may not be supported by their schools, such as those described in the Creative Production and Gaming chapters, often build relationships with others online through shared practice.
  • there are plenty of teens who relish the opportunity to make new connections through social media, this practice is heavily stigmatized
  • the public myths about online “predators” do not reflect the actual realities of sexual solicitation and risky online behavior (Wolak et al. 2008). Not only do unfounded fears limit teenagers unnecessarily, they also obscure preventable problematic behavior
  • As she described her typical session on Photobucket, it became clear that a shared understanding of friendship and romance was being constructed by her and other Photobucket users:
  • The fact that they draw from all of these sources suggests that youth’s friendship maintenance is in tune with a discourse of love and friendship that is being widely displayed and (re)circulated.
  • “It’s like have you noticed that you may have someone in your Top 8 but you’re not in theirs and you kinda think to yourself that you’re not as important to that person as they are to you . . . and oh, to be in the coveted number-one spot!”
  • Taking someone off your Top 8 is your new passive-aggressive power play when someone pisses you off.
  • Top Friends are persistent, publicly displayed, and easily alterable. This makes it difficult for teens to avoid the issue or make excuses such as “I forgot.” When pressured to include someone, teens often oblige or attempt to ward off this interaction by listing those who list them
  • Other teens avoid this struggle by listing only bands or family members. While teens may get jealous if other peers are listed, family members are exempt from the comparative urge.
  • to avoid social drama with her friends:
  • The Top Friends feature is a good example of how structural aspects of software can force articulations that do not map well to how offline social behavior works.
  • teens have developed a variety of social norms to govern what is and is not appropriate
  • The problem with explicit ranking, however, is that it creates or accentuates hierarchies where they did not exist offline, or were deliberately and strategically ambiguous, thus forcing a new set of social-status negotiations. The give-and-take over these forms of social ranking is an example of how social norms are being negotiated in tandem with the adoption of new technologies, and how peers give ongoing feedback to one another as part of these struggles to develop new cultural standards.
  • While teen dramas are only one component of friendship, they are often made extremely visible by social media. The persistent and networked qualities of social media alter the ways that these dramas play out in teen life. For this reason, it is important to pay special attention to the role that social media play in the negotiation of teen status.
  • primarily a continuation of broader dramas.
  • social media amplify dramas because they extend social worlds beyond the school.
  • Gossip and rumors have played a role in teen struggles for status and attention since well before social media entered the scene
  • social media certainly alter the efficiency and potential scale of interactions. Because of this, there is greater potential for gossip to spread much further and at a faster pace, making social media a culprit in teen drama. While teen gossip predates the Internet, some teens blame the technologies for their roles in making gossip easier and more viral
  • That’s what happened with me and my friends. We got into a lot of drama with it and I was like, anyone can write anything. It can be fact, fiction. Most people, what they read they believe. Even if it’s not true (C.J. Pascoe, Living Digital).
  • finds the News Feed useful “because it helps you to see who’s keeping track of who and who’s talking to who.” She enjoys knowing when two people break up so that she knows why someone is upset or when she should reach out to offer support. Knowing this information also prevents awkward conversations that might reference the new ex. While she loves the ability to keep up with the lives of her peers, she also realizes that this means that “everybody knows your business.”
  • Some teens find the News Feed annoying or irrelevant. Gadil, an Indian 16-year-old from Los Angeles, thinks that it is impersonal while others think it is downright creepy. For Tara, a Vietnamese 16-year-old from Michigan, the News Feed takes what was public and makes it more public: “Facebook’s already public. I think it makes it way too like stalker-ish.” Her 18-year-old sister, Lila, concurs and points out that it gets “rumors going faster.” Kat, a white 14-year-old from Salem, Massachusetts, uses Facebook’s privacy settings to hide stories from the News Feed for the sake of appearances.
  • While gossip is fairly universal among teens, the rumors that are spread can be quite hurtful. Some of this escalates to the level of bullying. We are unable to assess whether or not bullying is on the rise because of social media. Other scholars have found that most teens do not experience Internet-driven harassment (Wolak, Mitchell, and Finkelhor 2007). Those who do may not fit the traditional profile of those who experience school-based bullying (Ybarra, Diener-West, and Leaf 2007), but harassment, both mediated and unmediated, is linked to a myriad of psychosocial issues that includes substance use and school problems (Hinduja and Patchin 2008; Ybarra et al. 2007).
  • Measuring “cyberbullying” or Internet harassment is difficult, in part because both scholars and teens struggle to define it. The teens we interviewed spoke regularly of “drama” or “gossip” or “rumors,” but few used the language of “bullying” or “harassment” unless we introduced these terms. When Sasha, a white 16-year-old from Michigan, was asked specifically about whether or not rumors were bullying, she said: I don’t know, people at school, they don’t realize when they are bullying a lot of the time nowadays because it’s not so much physical anymore. It’s more like you think you’re joking around with someone in school but it’s really hurting them. Like you think it’s a funny inside joke between you two, but it’s really hurtful to them, and you can’t realize it anymore. Sasha, like many of the teens we interviewed, saw rumors as hurtful, but she was not sure if they were bullying. Some teens saw bullying as being about physical harm; others saw it as premeditated, intentionally malicious, and sustained in nature. While all acknowledged that it could take place online, the teens we interviewed thought that most bullying took place offline, even if they talked about how drama was happening online.
  • it did not matter whether it was online or offline; the result was still the same. In handling this, she did not get offline, but she did switch schools and friend groups.
  • Technology provides more channels through which youth can potentially bully one another. That said, most teens we interviewed who discussed being bullied did not focus on the use of technology and did not believe that technology is a significant factor in bullying.
  • They did, though, see rumors, drama, and gossip as pervasive. The distinction may be more connected with language and conception than with practice. Bianca, a white 16-year-old from Michigan, sees drama as being fueled by her peers’ desire to get attention and have something to talk about. She thinks the reason that people create drama is boredom. While drama can be hurtful, many teens see it simply as a part of everyday social life.
  • Although some drama may start out of boredom or entertainment, it is situated in a context where negotiating social relations and school hierarchies is part of everyday life. Teens are dealing daily with sociability and related tensions.
  • Tara thinks that it emerges because some teens do not know how to best negotiate their feelings and the feelings of others.
  • Teens can use the ability to publicly validate one another on social network sites to reaffirm a friendship.
  • So, while drama is common, teens actually spend much more time and effort trying to preserve harmony, reassure friends, and reaffirm relationships. This spirit of reciprocity is common across a wide range of peer-based learning environments we have observed.
  • From this perspective, commenting is not as much about being nice as it is about relying on reciprocity for self-gain
  • That makes them feel like they’re popular, that they’re getting comments all the time by different people, even people that they don’t know. So it makes them feel popular in a way (Rural and Urban Youth).
  • Gossip, drama, bullying, and posing are unavoidable side effects of teens’ everyday negotiations over friendship and peer status. What takes place in this realm resembles much of what took place even before the Internet, but certain features of social media alter the dynamics around these processes. The public, persistent, searchable, and spreadable nature of mediated information affects the way rumors flow and how dramas play out. The explicitness surrounding the display of relationships and online communication can heighten the social stakes and intensity of status negotiation. The scale of this varies, but those who experience mediated harassment are certainly scarred by the process. Further, the ethic of reciprocity embedded in networked publics supports the development of friendships and shared norms, but it also plays into pressures toward conformity and participation in local, school-based peer networks. While there is a dark side to what takes place, teens still relish the friendship opportunities that social media provide.
  • While social warfare and drama do exist, the value of social media rests in their ability to strengthen connections. Teens leverage social media for a variety of practices that are familiar elements of teen life: gossiping, flirting, joking around, and hanging out. Although the underlying practices are quite familiar, the networked, public nature of online communication does inflect these practices in new ways.
  • Adults’ efforts to regulate youth access to MySpace are the latest example of how adults are working to hold on to authority over teen socialization in the face of a gradual erosion of parental influence during the teen years.
  • learning how to manage the unique affordances of networked sociality can help teens navigate future collegiate and professional spheres where mediated interactions are assumed.
  • articulating those friendships online means that they become subject to public scrutiny in new ways;
  • This makes lessons about social life (both the failures and successes) more consequential and persistent
  • make these dynamics visible in a more persistent and accessible public arena.
  • co-constructing new sets of social norms together with their peers and the efforts of technology developers. The dynamics of social reciprocity and negotiations over popularity and status are all being supported by participation in publics of the networked variety as formative influences in teen life. While we see no indication that social media are changing the fundamental nature of these friendship practices, we do see differences in the intensity of engagement among peers, and conversely, in the relative alienation of parents and teachers from these social worlds.

Role and Function of Theory in Online Education Development and Delivery - 3 views

  • According to Bonk and Reynolds (1997), to promote higher-order thinking on the Web, online learning must create challenging activities that enable learners to link new information to old, acquire meaningful knowledge, and use their metacognitive abilities; hence, it is the instructional strategy and not the technology that influences the quality of learning.
  • However, it is not the computer per se that makes students learn, but the design of the real-life models and simulations, and the students' interaction with those models and simulations. The computer is merely the vehicle that provides the processing capability and delivers the instruction to learners (Clark, 2001).
  • ...35 more annotations...
  • Online learning allows for flexibility of access, from anywhere and usually at anytime—essentially, it allows participants to collapse time and space (Cole, 2000)—however, the learning materials must be designed properly to engage the learner and promote learning.
  • Cognitive psychology claims that learning involves the use of memory, motivation, and thinking, and that reflection plays an important part in learning.
  • The development of effective online learning materials should be based on proven and sound learning theories.
  • Early computer learning systems were designed based on a behaviorist approach to learning. The behaviorist school of thought, influenced by Thorndike (1913), Pavlov (1927), and Skinner (1974), postulates that learning is a change in observable behavior caused by external stimuli in the environment (Skinner, 1974).
  • Therefore, before any learning materials are developed, educators must, tacitly or explicitly, know the principles of learning and how students learn.
  • Constructivist theorists claim that learners interpret information and the world according to their personal reality, and that they learn by observation, processing, and interpretation, and then personalize the information into personal knowledge (Cooper, 1993; Wilson, 1997).
  • The design of online learning materials can include principles from all three. According to Ertmer and Newby (1993), the three schools of thought can in fact be used as a taxonomy for learning. Behaviorists' strategies can be used to teach the “what” (facts), cognitive strategies can be used to teach the “how” (processes and principles), and constructivist strategies can be used to teach the “why” (higher level thinking that promotes personal meaning and situated and contextual learning).
  • The behaviorist school sees the mind as a “black box,” in the sense that a response to a stimulus can be observed quantitatively, totally ignoring the effect of thought processes occurring in the mind.
  • Learners should be told the explicit outcomes of the learning so that they can set expectations and can judge for themselves whether or not they have achieved the outcome of the online lesson. 2.  Learners must be tested to determine whether or not they have achieved the learning outcome. Online testing or other forms of testing and assessment should be integrated into the learning sequence to check the learner's achievement level and to provide appropriate feedback. 3.  Learning materials must be sequenced appropriately to promote learning. The sequencing could take the form of simple to complex, known to unknown, and knowledge to application. 4.  Learners must be provided with feedback so that they can monitor how they are doing and take corrective action if required.
  • Cognitivists see learning as an internal process that involves memory, thinking, reflection, abstraction, motivation, and meta-cognition.
  • Online instruction must use strategies to allow learners to attend to the learning materials so that they can be transferred from the senses to the sensory store and then to working memory.
  • Online learning strategies must present the materials and use strategies to enable students to process the materials efficiently.
  • information should be organized or chunked in pieces of appropriate size to facilitate processing.
  • Use advance organizers to activate an existing cognitive structure or to provide the information to incorporate the details of the lesson (Ausubel, 1960).
  • Use pre-instructional questions to set expectations and to activate the learners' existing knowledge structure.
  • Use prerequisite test questions to activate the prerequisite knowledge structure required for learning the new materials.
  • To facilitate deep processing, learners should be asked to generate the information maps during the learning process or as a summary activity after the lesson (Bonk & Reynolds, 1997).
  • The cognitive school recognizes the importance of individual differences, and of including a variety of learning strategies in online instruction to accommodate those differences
  • The Kolb Learning Style Inventory (LSI) (Kolb, 1984) looks at how learners perceive and process information, whereas the Myers-Briggs Type Indicator (Myers, 1978) uses dichotomous scales to measure extroversion versus introversion, sensing versus intuition, thinking versus feeling, and judging versus perception. In the following discussion, we consider the Kolb Learning Style Inventory.
  • Attention: Capture the learners' attention at the start of the lesson and maintain it throughout the lesson. The online learning materials must include an activity at the start of the learning session to connect with the learners. Relevance: Inform learners of the importance of the lesson and how taking the lesson could benefit them. Strategies could include describing how learners will benefit from taking the lesson, and how they can use what they learn in real-life situations. This strategy helps to contextualize the learning and make it more meaningful, thereby maintaining interest throughout the learning session. Confidence: Use strategies such as designing for success and informing learners of the lesson expectations. Design for success by sequencing from simple to complex, or known to unknown, and use a competency-based approach where learners are given the opportunity to use different strategies to complete the lesson. Inform learners of the lesson outcome and provide ongoing encouragement to complete the lesson. Satisfaction: Provide feedback on performance and allow learners to apply what they learn in real-life situations. Learners like to know how they are doing, and they like to contextualize what they are learning by applying the information in real life.
  • Online strategies that facilitate the transfer of learning should be used to encourage application in different and real-life situations.
  • Constructivists see learners as being active rather than passive.
  • it is the individual learner's interpretation and processing of what is received through the senses that creates knowledge.
  • “the process of using a prior interpretation to construe a new or revised interpretation of the meaning of one's experience in order to guide future action” (p. 12).
  • Learning should be an active process. Keeping learners active doing meaningful activities results in high-level processing, which facilitates the creation of personalized meaning. Asking learners to apply the information in a practical situation is an active process, and facilitates personal interpretation and relevance.
  • Learners should construct their own knowledge rather than accepting that given by the instructor.
  • Collaborative and cooperative learning should be encouraged to facilitate constructivist learning (H
  • When assigning learners for group work, membership should be based on the expertise level and learning style of individual group members, so that individual team members can benefit from one another's strengths.
  •   Learners should be given control of the learning process
  • Learners should be given time and opportunity to reflect.
  • Learning should be made meaningful for learners. The learning materials should include examples that relate to students, so that they can make sense of the information.
  • Learning should be interactive to promote higher-level learning and social presence, and to help develop personal meaning. According to Heinich et al. (2002), learning is the development of new knowledge, skills, and attitudes as the learner interacts with information and the environment. Interaction is also critical to creating a sense of presence and a sense of community for online learners, and to promoting transformational learning (Murphy & Cifuentes, 2001). Learners receive the learning materials through the technology, process the information, and then personalize and contextualize the information.
  • Figure 1-6. Components of effective online learning.
  • Behaviorist strategies can be used to teach the facts (what); cognitivist strategies to teach the principles and processes (how); and constructivist strategies to teach the real-life and personal applications and contextual learning. There is a shift toward constructive learning, in which learners are given the opportunity to construct their own meaning from the information presented during the online sessions. The use of learning objects to promote flexibility and reuse of online materials to meet the needs of individual learners will become more common in the future. Online learning materials will be designed in small coherent segments, so that they can be redesigned for different learners and different contexts. Finally, online learning will be increasingly diverse to respond to different learning cultures, styles, and motivations.
  • Online instruction occurs when learners use the Web to go through the sequence of instruction, to complete the learning activities, and to achieve learning outcomes and objectives (Ally, 2002; Ritchie & Hoffman, 1997).

The End of Theory: The Data Deluge Makes the Scientific Method Obsolete - 137 views

  • The big target here isn't advertising, though. It's science. The scientific method is built around testable hypotheses. These models, for the most part, are systems visualized in the minds of scientists. The models are then tested, and experiments confirm or falsify theoretical models of how the world works.

    I dissagree. Maybe for someone who can cope with the massive scale Google works with but for the average student bah humbug. As far as the students I see the scientific method still needs to be taught as they need a lot of help learning how to gather reliable information from the web. As far as google is concerned the students simplistic, unevaluated searches are as valuable as someone who actually understands what they are looking for or maybe more valuable because more students are doing almost thoughtless searches. The real need is a good course, hopefully online, to teach students how to do a reasoned search. agoogleaday is a start.
