    "What is Digital History? Digital history is an approach to examining and representing the past that takes advantage of new communication technologies such as computers and the Web. It draws on essential features of the digital realm, such as databases, hypertextualization, and networks, to create and share historical knowledge. Digital history complements other forms of history-indeed, it draws its strength and methodological rigor from this age-old form of human understanding while using the latest technology."

    This article describes a new book, Reality Hunger, which is essentially a mashup of quotes from other sources. The article discusses how are culture of short-form writing and reading is changing literature and reading. The book reminds me of elements of a Humument, which also took the work of another and then augmented that work into a new story and art form.

  • As a rule, our experimental sessions began with long conversations which were sometimes repeated with the subjects in the relaxed atmosphere of a tea house, where the villagers spent most of their free time, or in camps in the field and in mountain pastures around the evening campfire. These talks were frequently held in groups. Even when the interviews were held with one person, the experimenter and other subjects made up a group of two or three who listened attentively to the person being interviewed and who sometimes offered remarks or comments on what he said. The talk often took the form of a free-flowing exchange of opinion between participants, and a particular problem might be solved simultaneously by two or three subjects, each proposing an answer. Only gradually did the experimenters introduce the prepared tasks, which resembled the “riddles” familiar to the population and therefore seemed like a natural extension of the conversation.

    COURSE OBJECTIVES: This is a graded internship that allows you to integrate your own coursework with a hands-on service learning experience. The central objective of this course is to provide students with community experiences and reflection opportunities that examine community needs, the importance of civic engagement, and social justice issues affecting ethnic minorities and marginalized populations in contemporary American society. Students dedicate 70 hours at a pre-approved site (including Title I K-12 schools, youth programs, health services, social services, environmental programs, government agencies, etc.) directly serving a population in need or supporting activities that contribute to the greater good of our community. A weekly seminar, course readings, discussions, and reflection assignments facilitate critical thinking and a deeper understanding of cultural diversity, citizenship, and how to contribute to positive social change in our community. The course is also designed to provide "real-world" experiences that exercise academic skills and knowledge applicable to each student‟s program of study and career exploration. STUDENT LEARNING OBJECTIVES: Student will be introduced to essential skills associated with their baccalaureate studies to actively serve the local community. While completing this in-depth study of cultural diversity, citizenship and social justice issues facing our community, students will gain an understanding of the value of Social Embeddedness and the importance of incorporating civic engagement into their collegiate careers, as they strive to become civically engaged students. Students will be introduced to inequalities, discrimination, and other community issues facing ethnic minorities and marginalized populations, as well as the correlation with greater societal issues. INTERNSHIP RESPONSIBILITIES:  Service hours - 70 hours of community outreach (spread throughout the semester in which you are enrolled in the course)

    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.

     Embedded in the very weave of the organisation, culture is the most difficult aspect of an organisation to change and the hardest form of change to sustain 'That's because transforming a culture requires influencing people's deepest beliefs and most habitual behaviours' (Rogers, Meehan & Tanne 2006 p5). Rogers et al indicate that as little as 10% of all organisations that set out to develop a high performing culture achieve their goal.

    When principals hear the words Twitter and Facebook they cringe. Immediately, visions of excessive socialization, time wasted, and meaningless conversations in the form of updates come to mind. This is true, in many cases, when these tools are used for personal use. I am here to share ways in which principals can harness the power of these free resources to improve communications, public relations, professional growth, instruction, and create a brand presence for your school. Quite simply, social media tools such as Twitter and Facebook have improved my effectiveness and efficiency as an educational leader.

  • When would-be college students apply for financial aid using the FAFSA, they are asked to list the colleges they are thinking about attending. The online version of the form asks applicants to submit up to 10 college names. The U.S. Department of Education then shares all the information on the FAFSA with all of the colleges on the list, as well as state agencies involved in awarding student aid. The form notes that the information could be used by state agencies, but there is no mention that individual colleges will use the information in admissions or financial aid -- and there is no indication that students could be punished by colleges for where they appear on the list.
  • Now, some colleges use this “FAFSA position” when considering students’ applications for admission, which may affect decisions about admission or placement on the wait list, said David Hawkins, director of public policy and research for the National Association for College Admission Counseling.
  • So the institution is disinclined to use up a precious admissions slot for a student who is unlikely to enroll.  “The student has no idea that this information is being used in this context,” Hawkins said. The federal government "doesn’t indicate it. Institutions certainly aren’t telling students they are using it. Certainly, this is a concern from this association’s standpoint.”
  • ...2 more annotations...
  • It's unclear if the Education Department was aware of this issue until contacted by Inside Higher Ed on Friday. The department now says it will review the longstanding practice of sharing the FAFSA positions with every college.
  • The use of the list on the FAFSA is just another example of how colleges are using increasingly sophisticated data mining techniques to recruit and shape their classes.

The Costs of Overemphasizing Achievement - 83 views

  • First, students tend to lose interest in whatever they’re learning. As motivation to get good grades goes up, motivation to explore ideas tends to go down. Second, students try to avoid challenging tasks whenever possible. More difficult assignments, after all, would be seen as an impediment to getting a top grade. Finally, the quality of students’ thinking is less impressive. One study after another shows that creativity and even long-term recall of facts are adversely affected by the use of traditional grades.

    • Terie Engelbrecht
      Terie Engelbrecht on 27 Jun 11
       
      Very true; especially the "avoiding challenging tasks" part.
  • Unhappily, assessment is sometimes driven by entirely different objectives--for example, to motivate students (with grades used as carrots and sticks to coerce them into working harder) or to sort students (the point being not to help everyone learn but to figure out who is better than whom)
  • Standardized tests often have the additional disadvantages of being (a) produced and scored far away from the classroom, (b) multiple choice in design (so students can’t generate answers or explain their thinking), (c) timed (so speed matters more than thoughtfulness) and (d) administered on a one-shot, high-anxiety basis.
  • ...36 more annotations...
  • The test designers will probably toss out an item that most students manage to answer correctly.
  • the evidence suggests that five disturbing consequences are likely to accompany an obsession with standards and achievement:
  • 1. Students come to regard learning as a chore.
  • intrinsic motivation and extrinsic motivation tend to be inversely related: The more people are rewarded for doing something, the more they tend to lose interest in whatever they had to do to get the reward.
  • 2. Students try to avoid challenging tasks.
  • they’re just being rational. They have adapted to an environment where results, not intellectual exploration, are what count. When school systems use traditional grading systems--or, worse, when they add honor rolls and other incentives to enhance the significance of grades--they are unwittingly discouraging students from stretching themselves to see what they’re capable of doing.
  • 3. Students tend to think less deeply.
  • 4. Students may fall apart when they fail.
  • 5. Students value ability more than effort
    • Deb White Groebner

      This is the reinforcement of a "fixed mindset" (vs. (growth mindset) as described by Carol Dweck.
  • They seem to be fine as long as they are succeeding, but as soon as they hit a bump they may regard themselves as failures and act as though they’re helpless to do anything about it.
  • When the point isn’t to figure things out but to prove how good you are, it’s often hard to cope with being less than good.
  • It may be the systemic demand for high achievement that led him to become debilitated when he failed, even if the failure is only relative.
  • But even when better forms of assessment are used, perceptive observers realize that a student’s score is less important than why she thinks she got that score.
  • just smart
  • luck:
  • tried hard
  • task difficulty
  • It bodes well for the future
  • the punch line: When students are led to focus on how well they are performing in school, they tend to explain their performance not by how hard they tried but by how smart they are.
  • In their study of academically advanced students, for example, the more that teachers emphasized getting good grades, avoiding mistakes and keeping up with everyone else, the more the students tended to attribute poor performance to factors they thought were outside their control, such as a lack of ability.
  • When students are made to think constantly about how well they are doing, they are apt to explain the outcome in terms of who they are rather than how hard they tried.
  • And if children are encouraged to think of themselves as "smart" when they succeed, doing poorly on a subsequent task will bring down their achievement even though it doesn’t have that effect on other kids.
  • The upshot of all this is that beliefs about intelligence and about the causes of one’s own success and failure matter a lot. They often make more of a difference than how confident students are or what they’re truly capable of doing or how they did on last week’s exam. If, like the cheerleaders for tougher standards, we look only at the bottom line, only at the test scores and grades, we’ll end up overlooking the ways that students make sense of those results.
  • the problem with tests is not limited to their content.
  • if too big a deal is made about how students did, thus leading them (and their teachers) to think less about learning and more about test outcomes.
  • As Martin Maehr and Carol Midgley at the University of Michigan have concluded, "An overemphasis on assessment can actually undermine the pursuit of excellence."
  • Only now and then does it make sense for the teacher to help them attend to how successful they’ve been and how they can improve. On those occasions, the assessment can and should be done without the use of traditional grades and standardized tests. But most of the time, students should be immersed in learning.
  • the findings of the Colorado experiment make perfect sense: The more teachers are thinking about test results and "raising the bar," the less well the students actually perform--to say nothing of how their enthusiasm for learning is apt to wane.
  • The underlying problem concerns a fundamental distinction that has been at the center of some work in educational psychology for a couple of decades now. It is the difference between focusing on how well you’re doing something and focusing on what you’re doing.
  • The two orientations aren’t mutually exclusive, of course, but in practice they feel different and lead to different behaviors.
  • But when we get carried away with results, we wind up, paradoxically, with results that are less than ideal.
  • Unfortunately, common sense is in short supply today because assessment has come to dominate the whole educational process. Worse, the purposes and design of the most common forms of assessment--both within classrooms and across schools--often lead to disastrous consequences.
  • grades, which by their very nature undermine learning. The proper occasion for outrage is not that too many students are getting A’s, but that too many students have been led to believe that getting A’s is the point of going to school.
  • research indicates that the use of traditional letter or number grades is reliably associated with three consequences.

  • Learning to see all behavior as a form of communication, for example, is a key principle that helps when teachers are frustrated or confused by how students are acting. Even though students’ behavior can look bizarre or disruptive, their actions are purposeful and are their attempts to solve a problem.
  • About 10 percent of the school population—or 9–13 million children—struggle with mental health problems. In a typical classroom of 20, chances are good that one or two students are dealing with serious psychosocial stressors relating to poverty, domestic violence, abuse and neglect, or a psychiatric disorder. There is also growing evidence that the number of children suffering the effects of trauma and those with autism-related social deficits is also on the rise.
  • ...4 more annotations...
  • If teachers are supported to set up classrooms to promote success, these students (and other challenging students who have similar behaviors but may not have individualized education plans, or IEPs) can improve their performance in school and in life.
  • Making positive attention more predictable in the classroom can help break the cycle of negative attention-seeking behaviors. Putting one-on-one time on the student’s personal visual schedule (even if it’s only a couple minutes to read a student’s favorite page in a book) or setting a timer for 10 minutes and telling the student that’s when you will be back are just two strategies that can help.
  • Teachers who work with challenging students need support from administrators and others in the school. It is very stressful to have a student in class who is constantly disruptive. In order to make the necessary investment, the teacher needs substantive support from administrators to avoid frustration and burnout and to garner the energy to provide effective interventions. When administrators delegate some of the teacher’s responsibilities to other people in the building, the teacher can devote more time to finding solutions. Regularly meeting with consultants (e.g., special educators, mental health professionals, and behavior analysts) can be essential for designing how the student progresses, but it also takes up the teacher’s prep time. If possible, the administrator can arrange coverage so that the teacher can meet with consultants at times other than lunch and prep. Support staff can instruct small groups of children while the teacher works with the student with behavior challenges. And since there are usually so many people involved with a struggling student, delineating a clear coordination plan is also critical. It can be helpful, as a team, to make a list of responsibilities and indicate who is responsible for what.
  • The more intensely the student is taught the underdeveloped skills, and the more the environment is changed to encourage appropriate behavior, the more quickly the student’s behavior is likely to change.

  • Other people with similar interest would also be able to see your highlights. Diigo also allows a group of people to pool findings through group bookmarks, highlights, sticky notes and forums. Diigo has groups that are already formed. You can join any Diigo group for collaborative research. People are also using Diigo by posting to their blog depending on tags. For me the best feature is the highlighting of the website. As we all know, research on the internet can be overwhelming. The highlighting feature makes it much easier. Not only do I have favorite websites bookmarked but I also have certain parts highlighted on that website. Educators can join the education group to search the web for anything that can help them with their classrooms. I also think that teachers can use Diigo to teach students how to do research. Better yet, educators can teach them how to do some collaborative research.
