Using Groups Effectively: 10 Principles » Edurati Review - 50 views

    "Conversation is key . Sawyer succinctly explains this principle: "Conversation leads to flow, and flow leads to creativity." When having students work in groups, consider what will spark rich conversation. The original researcher on flow, Mihaly Csikszentmihalyi, found that rich conversation precedes and ignites flow more than any other activity.1 Tasks that require (or force) interaction lead to richer collaborative conceptualization. Set a clear but open-ended goal . Groups produce the richest ideas when they have a goal that will focus their interaction but also has fluid enough boundaries to allow for creativity. This is a challenge we often overlook. As teachers, we often have an idea of what a group's final product should look like (or sound like, or…). If we put students into groups to produce a predetermined outcome, we prevent creative thinking from finding an entry point. Try not announcing time limits. As teachers we often use a time limit as a "motivator" that we hope will keep group work focused. In reality, this may be a major detractor from quality group work. Deadlines, according to Sawyer, tend to impede flow and produce lower quality results. Groups produce their best work in low-pressure situations. Without a need to "keep one eye on the clock," the group's focus can be fully given to the task. Do not appoint a group "leader." In research studies, supervisors, or group leaders, tend to subvert flow unless they participate as an equal, listening and allowing the group's thoughts and decisions to guide the interaction. Keep it small. Groups with the minimum number of members that are needed to accomplish a task are more efficient and effective. Consider weaving together individual and group work. For additive tasks-tasks in whicha group is expectedtoproduce a list, adding one idea to another-research suggests that better results develop

(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.

ERIC - Enhancing the Impact of Formative Feedback on Student Learning through an Online... - 49 views

    "Formative feedback is instrumental in the learning experience of a student. It can be effective in promoting learning if it is timely, personal, manageable, motivational, and in direct relation with assessment criteria. Despite its importance, however, research suggests that students are discouraged from engaging in the feedback process primarily for reasons that relate to lack of motivation and difficulty in relating to and reflecting on the feedback comments. In this paper we present Online FEdback System (OFES), an e-learning tool that effectively supports the provision of formative feedback. Our aims are to enhance feedback reception and to strengthen the quality of feedback through the way feedback is communicated to the students. We propose that an effective feedback communication mechanism should be integrated into a student's online learning space and it is anticipated that this provision will motivate students to engage with feedback. Empirical evidence suggests that the developed system successfully addressed the issues of student engagement and motivation and achieved its objectives. The results of using the system for two years indicate a positive perception of the students which, in turn, encourage us to further explore its effectiveness by extending its functionality and integrating it into a an open source learning management system"

The 7 Habits Of Effective Connected Educators | Edudemic - 115 views

  • Whether you’re using technology a lot or just dipping your proverbial toes in the digital water, this quick set of tips is perfect for you.For starters, you should know that effective connected educators always “start with the why” and don’t immediately adopt and deploy technology as soon as possible. They try to figure out “why” that particular piece of tech should have a lofty place in the classroom and where it would help.
    "Are you integrating technology or hoping to become a more effective teacher? If you circled one or both of those options, then listen up. Also, go grab a damp towel before that marker stays permanent on your computer monitor! Okay, all cleaned off? Let's learn about some of the must-know habits of effective connected educators."

      Please tell me what profession isn't always evolving? It something isn't evolving, it is dying! So, why doesn't everyone on the face of the earth - regardless of his/her profession or station in life - need coaching periodically to help them continue to grow and evolve?
  • We have to keep developing our capabilities and avoid falling behind.
  • no matter how well prepared people are in their formative years, few can achieve and maintain their best performance on their own.
  • outside ears, and eyes, are important
  • For decades, research has confirmed that the big factor in determining how much students learn is not class size or the extent of standardized testing but the quality of their teachers.
    • anonymous
      So, instead of having students take test after test after test, why don't we just have coaches who observe and sit and discuss and offer suggestions and divide the number of tests we give students in half and do away with half? Are we concerned about student knowledge? student performance? student ability? student growth or capacity for growth? What we really need to identify is what we value!
  • California researchers in the early nineteen-eighties conducted a five-year study of teacher-skill development in eighty schools, and noticed something interesting. Workshops led teachers to use new skills in the classroom only ten per cent of the time. Even when a practice session with demonstrations and personal feedback was added, fewer than twenty per cent made the change. But when coaching was introduced—when a colleague watched them try the new skills in their own classroom and provided suggestions—adoption rates passed ninety per cent. A spate of small randomized trials confirmed the effect. Coached teachers were more effective, and their students did better on tests.
    • anonymous
      Of course they are more effective! They have a trusted individual to guide them, mentor them, help sustain them. The coach can cheer and affirm what the teacher is already doing well and offer suggestions that are desired and sought in order to improve their 'game' and become more effective.
  • they did not necessarily have any special expertise in a content area, like math or science.
    • anonymous
      Knowledge of the content is one thing and expertise is yet another. Sometimes what makes us better teachers is simply strategies and techniques - not expertise in the content. Sometimes what makes us better teachers could simply be using a different tool or offering options for students to choose.
  • The coaches let the teachers choose the direction for coaching. They usually know better than anyone what their difficulties are.
    • anonymous
      The conversation with the coach and the coach listening and learning what the teacher would like to expand, improve, and grow is probably the most vital part! If the teacher doesn't have a clue, the coach could start anywhere and that might not be what the teacher adopts and owns. So, the teacher must have ownership and direction.
  • teaches coaches to observe a few specifics: whether the teacher has an effective plan for instruction; how many students are engaged in the material; whether they interact respectfully; whether they engage in high-level conversations; whether they understand how they are progressing, or failing to progress.

Educational Leadership:Feedback for Learning:Seven Keys to Effective Feedback - 87 views

  • Whether the feedback was in the observable effects or from other people, in every case the information received was not advice, nor was the performance evaluated. No one told me as a performer what to do differently or how "good" or "bad" my results were. (You might think that the reader of my writing was judging my work, but look at the words used again: She simply played back the effect my writing had on her as a reader.) Nor did any of the three people tell me what to do (which is what many people erroneously think feedback is—advice). Guidance would be premature; I first need to receive feedback on what I did or didn't do that would warrant such advice.
  • Decades of education research support the idea that by teaching less and providing more feedback, we can produce greater learning (see Bransford, Brown, & Cocking, 2000; Hattie, 2008; Marzano, Pickering, & Pollock, 2001).

  • But There's No Time!"
  • remember that feedback does not need to come only from the teacher, or even from people at all. Technology is one powerful tool—part of the power of computer-assisted learning is unlimited, timely feedback and opportunities to use it.
  • learners are often unclear about the specific goal of a task or lesson, so it is crucial to remind them about the goal and the criteria by which they should self-assess
  • I recommend that all teachers videotape their own classes at least once a month. It was a transformative experience for me when I did it as a beginning teacher.
  • research shows that less teaching plus more feedback is the key to achieving greater learning.
  • Even if feedback is specific and accurate in the eyes of experts or bystanders, it is not of much value if the user cannot understand it or is overwhelmed by it.
  • Adjusting our performance depends on not only receiving feedback but also having opportunities to use it.
  • Clearly, performers can only adjust their performance successfully if the information fed back to them is stable, accurate, and trustworthy. In education, that means teachers have to be on the same page about what high-quality work is. Teachers need to look at student work together, becoming more consistent over time and formalizing their judgments in highly descriptive rubrics supported by anchor products and performances.
  • Score student work in the fall and winter against spring standards, use more pre-and post-assessments to measure progress toward these standards, and do the item analysis to note what each student needs to work on for better future performance.
  • Effective supervisors and coaches work hard to carefully observe and comment on what they observed, based on a clear statement of goals. That's why I always ask when visiting a class, "What would you like me to look for and perhaps count?"
  • . Less teaching, more feedback. Less feedback that comes only from you, and more tangible feedback designed into the performance itself.
  • how we are doing in our efforts to reach a goal.
  • get another opportunity to receive and learn from the feedback.
  • computer games
  • quickly adapt
  • ack, do you have some ideas about how to improve?" This approach will build greater autono
  • ck, do you have some ideas about how to improve?" This approach will build greater autono
    Wiggins Advice, evaluation, grades-none of these provide the descriptive information that students need to reach their goals. What is true feedback-and how can it improve learning? Who would dispute the idea that feedback is a good thing? Both common sense and research make it clear: Formative assessment, consisting of lots of feedback and opportunities to use that feedback, enhances performance and achievement. Yet even John Hattie (2008), whose decades of research revealed that feedback was among the most powerful influences on achievement, acknowledges that he has "struggled to understand the concept" (p. 173). And many writings on the subject don't even attempt to define the term. To improve formative assessment practices among both teachers and assessment designers, we need to look more closely at just what feedback is-and isn't.

The Importance of Fluency and Automaticity for Efficient Reading - 43 views

    The reading process involves two separate but highly interrelated areas - word identification and comprehension. It is well established that difficulties in automatic word recognition significantly affect a reader's ability to effectively comprehend what they are reading (Lyon, 1995; Torgeson, Rashotte, and Alexander, 2001). Even mild difficulties in word identification can pull attention away from the underlying meaning, reduce the speed of reading, and create the need to reread selections to grasp the meaning. Many students who struggle to learn to read are able, with appropriate instruction, to compensate for initial reading problems by becoming accurate decoders but fail to reach a level of sufficient fluency to become fast and efficient readers. Thus, the development of techniques for improving automaticity and fluency is critical. Although the research is clear that a systematic alphabetic approach to teaching beginning readers is more effective than a whole word approach (Adams, 1990; Chall, 1996; Snow, Burns and Griffin, 1009), the most effect ways to develop fluency are less well understood.

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

  • 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
      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

Memory - Wikipedia, the free encyclopedia - 0 views

  • Encoding of working memory involves the spiking of individual neurons induced by sensory input, which persists even after the sensory input disappears (Jensen and Lisman 2005; Fransen et al. 2002). Encoding of episodic memory involves persistent changes in molecular structures that alter synaptic transmission between neurons. Examples of such structural changes include long-term potentiation (LTP) or spike-timing-dependent plasticity (STDP). The persistent spiking in working memory can enhance the synaptic and cellular changes in the encoding of episodic memory (Jensen and Lisman 2005).
  • Recent functional imaging studies detected working memory signals in both medial temporal lobe (MTL), a brain area strongly associated with long-term memory, and prefrontal cortex (Ranganath et al. 2005), suggesting a strong relationship between working memory and long-term memory. However, the substantially more working memory signals seen in the prefrontal lobe suggest that this area play a more important role in working memory than MTL (Suzuki 2007).
  • Consolidation and reconsolidation. Short-term memory (STM) is temporary and subject to disruption, while long-term memory (LTM), once consolidated, is persistent and stable. Consolidation of STM into LTM at the molecular level presumably involves two processes: synaptic consolidation and system consolidation. The former involves a protein synthesis process in the medial temporal lobe (MTL), whereas the latter transforms the MTL-dependent memory into an MTL-independent memory over months to years (Ledoux 2007). In recent years, such traditional consolidation dogma has been re-evaluated as a result of the studies on reconsolidation. These studies showed that prevention after retrieval affects subsequent retrieval of the memory (Sara 2000). New studies have shown that post-retrieval treatment with protein synthesis inhibitors and many other compounds can lead to an amnestic state (Nadel et al. 2000b; Alberini 2005; Dudai 2006). These findings on reconsolidation fit with the behavioral evidence that retrieved memory is not a carbon copy of the initial experiences, and memories are updated during retrieval.

  • Physical exercise, particularly continuous aerobic exercises such as running, cycling and swimming, has many cognitive benefits and effects on the brain. Influences on the brain include increases in neurotransmitter levels, improved oxygen and nutrient delivery, and increased neurogenesis in the hippocampus. The effects of exercise on memory have important implications for improving children's academic performance, maintaining mental abilities in old age, and the prevention and potential cure of neurological diseases.
  • At the Center for Cognitive Science at Ohio State University, researchers have found that memory accuracy of adults is hurt by the fact that they know more, and have more experience than children, and tend to apply all this knowledge when learning new information. The findings appeared in the August 2004 edition of the journal Psychological Science.
  • Interference can hamper memorization and retrieval. There is retroactive interference, when learning new information makes it harder to recall old information[59] and proactive interference, where prior learning disrupts recall of new information. Although interference can lead to forgetting, it is important to keep in mind that there are situations when old information can facilitate learning of new information. Knowing Latin, for instance, can help an individual learn a related language such as French – this phenomenon is known as positive transfer.[60]
  • Methods to optimize memorization[edit] Memorization is a method of learning that allows an individual to recall information verbatim. Rote learning is the method most often used. Methods of memorizing things have been the subject of much discussion over the years with some writers, such as Cosmos Rossellius using visual alphabets. The spacing effect shows that an individual is more likely to remember a list of items when rehearsal is spaced over an extended period of time. In contrast to this is cramming which is intensive memorization in a short period of time. Also relevant is the Zeigarnik effect which states that people remember uncompleted or interrupted tasks better than completed ones. The so-called Method of loci uses spatial memory to memorize non-spatial information.[72]

    Improving teacher effectiveness to lift student achievement has become a major theme in U.S. education. Most efforts focus on improving the effectiveness of teachers already in the classroom or on retaining the best performers and dismissing the least effective. Attracting more young people with stronger academic backgrounds to teaching has received comparatively little attention.

  • "Most jobs require computers," noted Brittnee Stephen, 16, as she assembled a slideshow on her HP Mini laptop. "It's good that we're learning it now."
    • Ed Webb
      The technology is still very visible, if students are talking in terms of 'computers' rather than the skills involved. We don't talk about 'paper' but writing, critical reading etc. Yet here the platform itself is emphasized. Early days, I guess.
  • has just begun incorporating technology
    • Ed Webb
      Uh, no. They have been using 'technology' forever, in the form of, say, books.
  • students seem far more interested in learning via interactive technology than they had been with a chalkboard and an overhead projector
    • Ed Webb
      Well, the problem here is that some of that can be ascribed to novelty. Once every class uses 'interactive technology' (yuk) then how much difference will there be? The tools are great. All tools can be useful. But focus on the pedagogy, people!
    • Scott Merrick
      I'm for focusing on understanding. I love the word "pedagogy" because most lay people don't really know what it entails--theory (which can be anything institutional or community deems effective or correct), practice (which, as we know, can be summed up with the phrase "mileage will vary"), and some third thing which if I could come up with it I'd have the magic 3 elements in an effective argument. I think effective tools used effectively by effective teachers (there! 3 uses of one adjective!) will remain effective as long as they are used to promote understanding. No argument here, Ed, just sayin'...
    • Ed Webb
      Perhaps the magic third thing would be 'attitude' or 'state of mind'? Alternatively, perhaps another of those non-transparent terms, 'praxis'. The point I was trying to make, of course, was that it ain't what you use, it's the way that you use it.
  • "I think the kids that have turned school off because it's boring to them will come here and see something familiar,"
    • Ed Webb
      Boring and familiar seem to me to be closely related, not opposites. I suspect that often when students say their learning environment is 'boring' they mean 'challenging'.
  • Educational technology does not come cheaply
    • Ed Webb
      The cost of books is astronomical!
  • "Learning is changing,"
    • Ed Webb
      Was it EVER the case that we could "just deliver a lecture and expect all the kids to get it"?
    • Gregory Louie
      Computer technology in my classroom has revolutionized my teaching of biology. Instead of static images on a printed page, or talk and chalk, my students can manipulate 3-D images of DNA, RNA and proteins. These have even been embedded in a research-based learning progression that leads the students to a robust understanding of the foundational elements of molecular literacy. 1. Atoms and molecules are constantly in motion. (A visualization is not possible on a 2-3 printed page.) 2. All atoms and molecules have a 3-D structure that determines how they interact with other particles. 3. Charges and other intermolecular forces play a role in atomic and molecular interactions. My students can see these for themselves, change the number of particles in a box, or the distribution of charge on a large particle or the temperature of the box and other thought experiments which they can follow in real-time. There is no way, I could do that without the computer!

  • Home Advocacy Top Ten in '10: ISTE's Education Technology Priorities for 2010 Through a common focus on boosting student achievement and closing the achievement gap, policymakers and educators alike are now reiterating their commitment to the sorts of programs and instructional efforts that can have maximum effect on instruction and student outcomes. This commitment requires a keen understanding of both past accomplishment and strategies for future success. Regardless of the specific improvement paths a state or school district may chart, the use of technology in teaching and learning is non-negotiable if we are to make real and lasting change.  With growing anticipation for Race to the Top (RttT) and Investing in Innovation (i3) awards in 2010, states and school districts are seeing increased attention on educational improvement, backed by financial support through these grants. As we think about plans for the future, the International Society for Technology in Education (ISTE) has identified 10 priorities essential for making good on this commitment in 2010: 1. Establish technology in education as the backbone of school improvement . To truly improve our schools for the long term and ensure that all students are equipped with the knowledge and skills necessary to achieve in the 21st century, education technology must permeate every corner of the learning process. From years of research, we know that technology can serve as a primary driver for systemic school improvement, including school leadership, an improved learning culture and excellence in professional practice. We must ensure that technology is at the foundation of current education reform efforts, and is explicit and clear in its role, mission, and expected impact. 2. Leverage education technology as a gateway for college and career readiness . Last year, President Obama established a national goal of producing the highest percentage of college graduates in the world by the year 2020. To achieve this goal in the next 10 years, we must embrace new instructional approaches that both increase the college-going rates and the high school graduation rates. By effectively engaging learning through technology, teachers can demonstrate the relevance of 21st century education, keeping more children in the pipeline as they pursue a rigorous, interesting and pertinent PK-12 public education. 3. Ensure technology expertise is infused throughout our schools and classrooms.  In addition to providing all teachers with digital tools and content we must ensure technology experts are integrated throughout all schools, particularly as we increase focus and priority on STEM (science-technology-engineering-mathematics) instruction and expand distance and online learning opportunities for students. Just as we prioritize reading and math experts, so too must we place a premium on technology experts who can help the entire school maximize its resources and opportunities. To support these experts, as well as all educators who integrate technology into the overall curriculum, we must substantially increase our support for the federal Enhancing Education Through Technology (EETT) program.  EETT provides critical support for on-going professional development, implementation of data-driven decision-making, personalized learning opportunities, and increased parental involvement. EETT should be increased to $500 million in FY2011. 4. Continuously upgrade educators' classroom technology skills as a pre-requisite of "highly effective" teaching . As part of our nation's continued push to ensure every classroom is led by a qualified, highly effective teacher, we must commit that all P-12 educators have the skills to use modern information tools and digital content to support student learning in content areas and for student assessment. Effective teachers in the 21st Century should be, by definition, technologically savvy teachers. 5. Invest in pre-service education technology
