Is Real Educational Reform Possible? If So, How? | Psychology Today - 3 views

  • Children come into the world intensely motivated to learn about the physical, social, and cultural world around them; but they need freedom in order to pursue that motive.  For their first four or five years of life we generally grant them that freedom. During those first few years, without any teaching, they learn a large portion of what any human being ever learns. They learn their entire native language, from scratch. They learn the basic practical principles of physics. They learn psychology to such a degree that they become experts in how to please, annoy, manipulate, and charm the other people in their environment.  They acquire a huge store of factual knowledge.  They learn how to operate the gadgets that they are allowed to operate, even those that seem extraordinarily complex to us adults.They do all this on their own initiative, with essentially no direction from adults.

  • From a parent's perspective (and sometimes from the child's), this can seem like we are "de-gifted" the child.
  • The most important thing is that you have the "data" that shows what the student needs and that you are matching this with an appropriate service.
  • Be very explicit with what the differentiation is and how it is addressing the needs
  • A major shift with RTI is that there is less emphasis on the "label" and more on the provision of appropriate service.

  • One is focusing on remediation, however the second approach focuses on the nurturing of potential through creating expectations for excellence that permeate Tier 1 with extended opportunities for enrichment for all children who need them at Tier 2. With the focus on excellence, the rising tide will help all students reach their potential. This is the goal of education.
  • make sure that the screener is directly related to the curriculum that you are using and that it has a high enough ceiling to allow advance learners to show what they know.
  • recognizing that students who are above grade level, or advanced in their academics, also need support to thrive
  • all students deserve to attend a school where their learning needs are met
  • seek out ways to build the knowledge and skills of teachers to address the range of needs
  • This includes learning about differentiated instruction within Tier 1and creating additional opportunities for enhancements and enrichments within Tier 2.
  • first
  • This often means that the district views the school as a “high-needs” school and does feel that many children would qualify for gifted education services (thus no teacher allocation is warranted). If this is the case, then this is a problematic view as it perpetuates the myth that some groups of children are not likely to be “gifted”.
  • These five differentiation strategies are as follows: Curriculum Compacting (pre-assessment of learners to see what they know)  The use of Tiered Assignments that address: Mastery, Enrichment, and Challenge  Tiered Learning Centers that allow children to further explore skills and concepts  Independent and Small group learning contracts that allow students to follow area of interest  Questioning for Higher Level thinking to stretch the minds of each child.

"Booksprints" - fast track to rigorous open educational resources | Education4site - 32 views

  •  
    "The Finnish group used a methodology called "Booksprint" which was developed to produce manuals for Free/Libre Open Source Software (FLOSS). The method has already been used to produce over 40 FLOSS manuals. Booksprints involve a large number of individuals with various relevant backgrounds working collaboratively, either remotely or locally, to produce published books, usually within 2-5 days. The method requires intensive pre-planning culminating in an "unconference" at which the text is written, edited and prepared for publication. Participants make extensive use of open source methodologies and tools to facilitate sharing, versioning, and tracking, ex. using GitHub."

Educational Leadership:Faces of Poverty:Boosting Achievement by Pursuing Diversity - 19 views

    • Matt Renwick
       
      This is a critical point. Allowing middle class families to pick and choose where there kids should go without valid reasons (i.e. work) can hurt high poverty schools.
    • Matt Renwick

  • Residential poverty tends to be concentrated, and successful school integration requires either a district with enough socioeconomic diversity within its boundaries or a group of neighboring districts which, when combined, have enough diversity to facilitate an interdistrict integration plan.

  • A weighted lottery is the simplest way for schools to ensure that they enroll a diverse student body while still relying on choice-based enrollment.
    • Matt Renwick
       
      A possible solution?
  • ndividual success stories and a review of research suggest that it is possible, by offering all students a single challenging curriculum, to reduce the achievement gap without harming the highest achievers (Burris, Wiley, Welner, & Murphy, 2008; Rui, 2009).
  • In the middle grades, students at City Neighbors start their day with half an hour of highly specialized, small-group instruction called intensive. Intensive provides an opportunity for extra support or enrichment in different subjects, allowing teachers to meet different students' needs while still teaching most of the academic time in mixed-ability classrooms.
    • Matt Renwick
       
      Sounds like an intervention block, something many buildings have or are looking at.
  • small but growing number of schools are attempting to boost the achievement of low-income students by shifting enrollment to place more low-income students in mixed-income schools. Socioeconomic integration is an effective way to tap into the academic benefits of having high-achieving peers, an engaged community of parents, and high-quality teachers.
  • A 2010 meta-analysis found that students of all socioeconomic statuses, races, ethnicities, and grade levels were likely to have higher mathematics performance if they attended socioeconomically and racially integrated schools (Mickelson & Bottia, 2010).
  • Research supporting socioeconomic integration goes back to the famous Coleman Report, which found that the strongest school-related predictor of student achievement was the socioeconomic composition of the student body (Coleman et al., 1966).
  • nd results of the 2011 National Assessment of Educational Progress in mathematics show steady increases in low-income 4th graders' average scores as the percentage of poor students in their school decreases (U.S. Department of Education, 2011).
  • a number of studies have found that the relationship between student outcomes and the socioeconomic composition of schools is strong even after controlling for some of these factors, using more nuanced measures of socioeconomic status, or comparing outcomes for students randomly assigned to schools (Reid, 2012; Schwartz, 2012).
  • Rumberger and Palardy (2005) found that the socioeconomic composition of the school was as strong a predictor of student outcomes as students' own socioeconomic status.
  • Socioeconomic integration is a win-win situation: Low-income students' performance rises; all students receive the cognitive benefits of a diverse learning environment (Antonio et al., 2004; Phillips, Rodosky, Muñoz, & Larsen, 2009); and middle-class students' performance seems to be unaffected up to a certain level of integration.
  • A recent meta-analysis found "growing but still inconclusive evidence" that the achievement of more advantaged students was not harmed by desegregation policies (Harris, 2008, p. 563).
  • he findings suggested that, more than a precise threshold, what mattered in these schools was maintaining a critical mass of middle-class families, which promoted a culture of high expectations, safety, and community support.
  • istricts have chosen to let school boundaries reflect or even amplify residential segregation.

Cyberkids or divided generations? Characterising young people's internet use in the UK ... - 0 views

  •  
    Young people are often characterised as cyberkids in reference to an assumed intense engagement and natural affinity with the internet. This article critiques the empirical basis for such claims and explores two alternative perspectives: namely, continua of use and typologies of use. Using UK data on 12-15 year old home internet users, a series of descriptive and latent class analyses of young people's internet use is presented. Results show there is little support for cyberkid characterisations and a proposed continuum of use is also shown to not fit the data. A three-way typology of use is instead presented which suggests a third of young home internet users make only limited use of the internet and the remaining two-thirds diverge into informational and creational/communicative users. These findings are used to argue that Mannheim's notion of generational units may be a useful way to characterise young people's internet use.

    Martin van Hemert is a photographer based in Utah. He is actively involved in architectural, product, and fine art photography. Throughout his career, he has consistently been drawn to more labor intensive forms of the art, from baking films in hydrogen for astronomical photography, to long exposures and light painting of outdoor scenes photographed on 4×5 sheet films, to his current obsession with spherical panoramas. Born to a family of Dutch immigrants, he studied music at the University of Utah, following which he made the logical choice of a career in photography. Martin and his wife are the parents of three grown children and one un-grown grandchild, and live in rural Utah County with a small herd of horses. Their rodent control staff boasts 7 members.

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.

Embedding academic writing instruction into subject teaching: A case study - 0 views

  •  
    The benefits of embedding the teaching of writing into the curriculum have been advocated by educators and researchers. However, there is currently little evidence of embedded writing instruction in the UK's higher education context. In this article, we present a case study in which we report the design, implementation and evaluation of an academic writing intervention with first-year undergraduate students in an applied linguistics programme. Our objectives were to try a combination of embedded instructional methods and provide an example that can be followed by lecturers across disciplines and institutions. Through the integration of in-class and online writing tasks and assessment feedback in a first-term module, we supported students' writing development throughout the first term. We evaluated the effects of the intervention through the analysis of notes on classroom interaction, a student questionnaire and interviews, and a text analysis of students' writing and the feedback comments over time. The evaluation findings provide insights into the feasibility and effectiveness of this approach. The embedded writing instruction was perceived as useful by both students and teachers. The assessment feedback, whilst being the most work-intensive method for the teachers, was valued most by the students and led to substantial improvements in the writing of some. These findings suggest that embedded writing instruction could be usefully applied in other higher education contexts.

Scientists make quantum breakthrough - 25 views

  • Scientists have demonstrated for the first time that atoms can be guided in a laser beam and possess the same properties as light guided in an optical communications fiber.
  • Abstract Speckle patterns produced by multiple independent light sources are a manifestation of the coherence of the light field. Second-order correlations exhibited in phenomena such as photon bunching, termed the Hanbury Brown–Twiss effect, are a measure of quantum coherence. Here we observe for the first time atomic speckle produced by atoms transmitted through an optical waveguide, and link this to second-order correlations of the atomic arrival times. We show that multimode matter-wave guiding, which is directly analogous to multimode light guiding in optical fibres, produces a speckled transverse intensity pattern and atom bunching, whereas single-mode guiding of atoms that are output-coupled from a Bose–Einstein condensate yields a smooth intensity profile and a second-order correlation value of unity. Both first- and second-order coherence are important for applications requiring a fully coherent atomic source, such as squeezed-atom interferometry.

Mental Health: Coping with Stress - 5 views

    "There are lots of stressful careers, but teaching combines the elevated baseline of chonic stress of the day to day, coupled with bouts of intensely stressful events. Inspections, staff meetings, work scrutiny, piles of unmarked books in the boot of your car, all can cause stress and anxiety. Plus the current culture of the profession, where boasts about the long hours individuals work are wore like medals rather than alarm bells, make us feel inadequate unless we are working ourselves to the verge of medical exhaustion."
