Digitally Speaking / Blogging - 169 views

  • Using Feed Readers

     

    Feed readers are probably the most important digital tool for today's learner because they make sifting through the amazing amount of content added to the Internet easy.  Also known as aggregators, feed readers are free tools that can automatically check nearly any website for new content dozens of times a day---saving ridiculous amounts of time and customizing learning experiences for anyone. 

     

    Imagine never having to go hunting for new information from your favorite sources again.  Learning goes from a frustrating search through thousands of marginal links written by questionable characters to quickly browsing the thoughts of writers that you trust, respect and enjoy.

     

    Sounds too good to be true, doesn't it?

     

    It's not!  Here's a Commoncraft tutorial explaining RSS Feeds in Plain English:

     

    Feed readers can quickly and easily support blogging in the classroom, allowing teachers to provide students with ready access to age-appropriate sites of interest that are connected to the curriculum.  By collecting sites in advance and organizing them with a feed reader, teachers can make accessing information manageable for their students. 

    Here are several examples of feed readers in action:

     

    Student Blogs

    http://www.pageflakes.com/wferriter/20982438

     

     

    This feed list includes several elementary, middle and high school blogs that students can explore during silent reading or while online at home.

     

     

    Current Events 

    http://www.pageflakes.com/wferriter/16714925

     

    This feed list includes links to several news websites that cover topics that are a part of one teacher's required social studies curriculum. 

     

    Global Warming

    http://www.pageflakes.com/wferriter/22534539

    Used specifically as a part of one classroom project, this feed list contains information related to global warming that students can use as a starting point for individual research. 

     

    While there are literally dozens of different feed reader programs to choose from (Bloglines and Google Reader are two biggies), Pageflakes is a favorite of many educators because it has a visual layout that is easy to read and interesting to look at.  It is also free and web-based.  That means that users can check accounts from any computer with an Internet connection.  Finally, Pageflakes makes it quick and easy to add new websites to a growing feed list—and to get rid of any websites that users are no longer interested in.

    What's even better:  Pageflakes has been developing a teacher version of their tool just for us that includes an online grade tracker, a task list and a built in writing tutor.  As Pageflakes works to perfect its teacher product, this might become one of the first kid-friendly feed readers on the market. Teacher Pageflakes users can actually blog and create a discussion forum directly in their feed reader---making an all-in-one digital home for students.

How Can We Make Assessments Meaningful? | Edutopia - 170 views

  • Criteria for a Meaningful Classroom Assessment To address these requirements, I ask myself the following guided questions: Does the assessment involve project-based learning? Does it allow for student choice of topics? Is it inquiry based? Does it ask that students use some level of internet literacy to find their answers? Does it involve independent problem solving? Does it incorporate the 4Cs? Do the students need to communicate their knowledge via writing in some way? Does the final draft or project require other modalities in its presentation? (visual, oral, data, etc...)
  • So how can high-stakes assessments be meaningful to students? For one thing, high-stakes tests shouldn't be so high-stakes. It's inauthentic. They should and still can be a mere snapshot of ability. Additionally, those occasional assessments need to take a back seat to the real learning and achievement going on in every day assessments observed by the teacher. The key here, however, is to assess everyday. Not in boring, multiple-choice daily quizzes, but in informal, engaging assessments that take more than just a snapshot of a student's knowledge at one moment in time. But frankly, any assessment that sounds cool can still be made meaningless. It's how the students interact with the test that makes it meaningful. Remember the 4 Cs and ask this: does the assessment allow for: Creativity Are they students creating or just regurgitating? Are they being given credit for presenting something other than what was described? Collaboration Have they spent some time working with others to formulate their thoughts, brainstorm, or seek feedback from peers? Critical Thinking Are the students doing more work than the teacher in seeking out information and problem solving? Communication Does the assessment emphasize the need to communicate the content well? Is there writing involved as well as other modalities? If asked to teach the content to other students, what methods will the student use to communicate the information and help embed it more deeply?
  • Another way to ensure that an assessment is meaningful, of course, is to simply ask the students what they thought. Design a survey after each major unit or assessment. Or, better yet, if you want to encourage students to really focus on the requirements on a rubric, add a row that's only for them to fill out for you. That way, the rubric's feedback is more of a give-and-take, and you get feedback on the assessment's level of meaningfulness as soon as possible.

(PDF) A Systematic Review of Treatments for Music Performance Anxiety - 2 views

  • Four other studies (three of which are dissertations) assessed behavioral treatments forMPA on music students. Grishman (1989) and Mansberger (1988) used standard musclerelaxation techniques, Wardle (1969) compared insight/relaxation and systematic desensi-tisation techniques, and Deen (1999) used awareness and breathing techniques
  • A systematic review of all available treatment studies for music performance anxiety was undertaken.
  • reported that 24% of musicians frequently suffered stage fright, defined in this study as themost severe form of MPA, 13% experienced acute anxiety and 17% experienceddepression.
  • ...24 more annotations...
  • 59% of musicians in symphony orchestras reported performance anxiety severe enough toimpair their professional and/or personal functioning.
  • A recent study indicated that MPA is not limited to orchestralmusicians, showing that opera chorus artists are also prone to high levels of performanceanxiety
  • However, since not allperformers suffer the same degree of MPA, or indeed report the same levels of occupationalstress, individual differences in a range of psychological characteristics are likely to accountfor variations in the degree to which musicians experience symptoms
  • A large number of treatment modalities (e.g., behavioral, cognitive, pharmacological andcomplementary) has been developed for music performance anxiety (MPA)
  • However, areview of this literature indicates that the field is still in its infancy with respect to theconceptual and theoretical formulations of the nature of MPA and its empiricalinvestigation.
  • Anxiety may be triggered by conscious,rational concerns or by cues that trigger, unconsciously, earlier anxiety producingexperiences or somatic sensations.
  • These findings suggest that multi-modal interventions are needed toaddress the multiple difficulties experienced by test anxious individuals.
  • with some focusing on behavioral change, some on cognitivechange, others on reduction of physiological symptoms through the use of pharmacotherapy,and some on idiosyncratic formulations
  • For drug studies, the keywords were beta-blocker [Beta blockers block the effect ofadrenaline (the hormone norepinephrine) on the body’s beta receptors. This slows downthe nerve impulses that travel through the heart. As a result, the resting heart rate is lower,the heart does not have to work as hard and requires less blood and oxygen
  • Brodsky (1996) and Nube´(1991) were most useful.
  • The interventionsassessed included systematic desensitization, progressive muscle relaxation, awareness andbreathing and behavioural rehearsal
  • In summary, behavioral treatments do appear to be at least minimally effective in thetreatment of MPA, although the heterogeneity of the treatment approaches employedmakes it difficult to isolate consistent evidence for the superiority of any one type ofbehavioral intervention
  • Two studies (see Tables II and IV) assessed the therapeutic effect of cognitive techniquesalone on MPA.
  • A dissertation by Patston (1996) reported a comparison of cognitive (e.g.positive self-talk, etc.) and physiological strategies in the treatment of MPA. No significantimprovements on vocal and visual manifestations of performance anxiety were found foreither treatment or control groups. However, the sample consisted of only 17 operastudents who were not specifically selected on the basis of their MPA severity, and theintervention was conducted by the author, a singer and teacher, who had no training inpsychology.
  • Three studies (see Table III) assessed the therapeutic effect of cognitive-behavioralstrategies on MPA. Harris (1987), Roland (1993), and Kendrick et al. (1982) all reportedthat standard CBT techniques were effective in the treatment of MPA in studentsspecifically selected for study because of the severity of their MPA.
  • Harris (1987) and Roland(1993) reported that CBT led to reductions in state anxiety as measured by the STAI,although Kendrick et al. (1982) failed to find a significant difference between treatment andcontrol groups on this measure.
  • The evidence for improvements in MPA following CBT is quite consistent, althoughfurther studies with larger samples are needed to confirm this evidence.
  • Beta-blockers have become increasingly popular among performers in recent years. Forexample, Lockwood (1989), in a survey of 2,122 orchestral musicians, found that 27% usedpropranolol to manage their anxiety prior to a performance; 19% of this group used thedrug on a daily basis.
  • Nube´ (1991) identified nine studies examining the effects of various beta-blockers(Atenolol, Metopolol, Nadolol, Oxprenolol, Propranolol, Pindolol) on MPA.
  • The findings regarding the effects of beta blockers on otheroutcome measures were less conclusive.
  • A rigorous definition of MPA is needed to advance treatment. However, defining MPA as asocial anxiety (social phobia) using criteria set out in DSM-IV-TR (APA, 2000) as theinclusion criteria may be too restrictive, particularly if the musician presenting for treatmentexperiences MPA as a focal anxiety (ie does not meet other criteria for social anxiety).
  • Few ofthe intervention studies reviewed acknowledged that performers need a certain amount ofarousal or anxiety to maximise their performance.
  • None of the studies could be pooled in a meta-analysis primarily because too fewprovided sufficient data to calculate effect sizes, use of diverse subject groups andtreatments, duration and intensity of treatment, and use of disparate outcome measures
  • In conclusion, the literature on treatment approaches for MPA is fragmented, incon-sistent, and methodologically weak. These limitations make it difficult to reach any firmconclusions about the effectiveness of the various treatment approaches reviewed. Forsignificant progress to be made, future research will require a clear definition of MPA,consistency and strength in methodology, and the development of robust and appropriateoutcome measures.
