Coding JavaScript for Mobile Browsers (part 6) - Microsoft Certification Examples, exer... - 0 views

  • In mobile browsers, you need to be especially careful about using timers because of the battery consumption. If you need to use many high-frequency timers at the same time, try to manage them using only one timer that will launch different behaviors from the same process.
  • The first question we need to ask ourselves is, what happens when our web page goes to the background because the user switches focus to another application (in multitasking operating systems) or opens or browses to another tab or window? Another problem is what happens when the phone goes to sleep (because of the user’s inactivity while the script is executing). The behavior of timers can be a little tricky in these situations.Yet another problem is that timers execute on the same thread as the main script. If our script is taking too much processor time (a normal situation with large scripts on low- and mid-end devices), our timers will be delayed until some spare execution time is found.If we use a low frequency for the timer (for example, 10 milliseconds), the timer will generally have problems meeting the timetable.Remember that the JavaScript execution time depends a lot on the device hardware and the browser’s engine. Even if they’re running the same operating system, like Android, execution times can differ: for example, an HTC G1 will be much slower than a Nexus One with a 1-Ghz processor.
  • As shown in Figure 4, the real times are very different on different devices. On low- and mid-end devices, if they work at all, the result is far from our 200 ms intention—some low-end devices don’t even accept timers with a frequency of less than 1 second.

The conclusions are: for low-frequency timers (1 second or more), there are no performance issues, and you can add as many as you want; for high-frequency timers (for example, 100 ms), though, every new timer created makes the UI more sluggish. The preferred solution is to use only one high-frequency timer.

Apple Study Trip: Day 2 ~ ICT For Educators - 5 views

  •  When students were given their own iPad, they were given full autonomy of their device and had to set it up from scratch. They set up all of their own accounts and installed their own apps, from a combination of required apps to those which they chose themselves. Each student was given a $40 iTunes gift card to use for their purchases. Experience showed that true success relied on moving away from the school being the "boss" of the machine to one where it was student driven and student managed. 
  • It was found that the Ipads are very different from laptops in that students can really relate to them and, when used, they do not become the focus of the learning. Instead they become one device which can be used with all learning tools that students have access to. The iPad became the "red pen" where much of the work got done in other ways and the iPad was used when needed. Laptop computers control thinking and control the desk. When used, they become the focus of the learning. iPads are a technology which has really changed the way students work with computers in the classroom. The real challenge for staff is to embrace this and to understand that you can't expect to have iPads in the classroom and teach the same way that you did when you didn't have them. It changes the way students work and they way teachers teach. 
  •  
    Like your comment about how the iPads don't become the focus of the learning. That's a thought that's been on my mind recently - the importance of the perception of "seamlessness" in tech usage. That's probably one of the most important reasons a technology gets adapted - no matter how cumbersome it seems at first (e.g. learning how to drive a car) - because the normal usage of the technology doesn't hinder the intended task at hand. (That's why once you learn to ride a bike, you don't think so much about the bicycle itself as you think about moving faster.) Think Donald Norman in "The Design of Everyday Things" has a term for this: affordability. So I guess, my thought on the usage of the iPad (and any new tech at hand): The learning of the new tech need not be intuitive. But the everyday usage has to seamlessly flow with the given task at hand - so that the tool and the user become "one" with the task. (Just like how a user fumbles with a pair of chopsticks at first, but once he masters it, his chopsticks "become" part of his fingers.) Then such seamless technologies get seamlessly adopted as "cognitive-multipliers".

SpringerLink - Education and Information Technologies, Online First™ - 0 views

  • A Video Lecture Capture (VLC) system was implemented to address issues relating to retention, and to reverse the trend of high drop, failure, and withdrawal (DFW) rates. The purpose of this study was to examine student perceptions of how using VLC impacted their academic performance. Areas of interest surrounded students’ perceived benefits, value, and helpfulness of using the system. In addition, the study probed the concern of many about the impact using VLC would have upon class attendance. Finally the study compared students’ perceptions about their performance as a result of using VLC with faculty perceptions about their students’ performance as a result of using VLC. It was hypothesized that there is a significant difference between student and faculty perceptions.

Here Come the iPads - Now What? iPad Deployment « Moving at the Speed of Crea... - 2 views

  • App considerations - What store? - we have chosen to live within the spirit of agreements rather than line item agreements - on issue is: “The iTunes Service is available to you only in the United States, its territories, and possessions. You agree not to use or attempt to use the iTunes Service from outside these locations. Apple may use technologies to verify your compliance.” We have made peace with using the U.S. store and dealing with it, the Chinese store has far fewer apps and isn’t nearly as good a fit for our student population We created iTunes accounts with gift cards, purchased in the USA - no one used a credit card for apps Volume Purchasing Plan (VPP) is the answer to many of these questions - lets a site administrator have control over iPads and iOS devices in the school ecosystem - this is only available as of today in the United States (not in China) - is coming to other countries, the legal issues are being worked out
  • Suggested management solution from 1 of the vendors present at this session: - create a separate iTunes account for each iPad you have - then have 1 account to hold the money: that account then “gifts” money to individual iTunes account (gift certificates) So now as things exist, we buy large ($100) cards for our main, master iTunes account - we also purchase smaller cards ($10) for innovator teachers to try different apps

8 Cool Marketing Campaigns Using Facebook Places - 1 views

  • Promoting Events Electronic Arts U.K. hosted a “Play4Xmas” tour at six different shopping malls across the UK in November and December. Those who checked in at each event had a chance to win up to 10 games per day.
  • Ambush Marketing Instead of paying an arm and a leg for an exhibition table at the ITB Berlin (the world’s largest travel tradeshow), Germanwings used Facebook Places to create check-ins at each one of its competitors at the fair. When someone checked in at an airline’s booth, their status update would read something like “Air France: France for a bargain price is only available from Germanwings” thanks to their hidden messages.
  • Facebook Places provides viral marketing for a company since every check-in shows up in the news feed of the user’s friends. It allows businesses to create incentives for those who come to their physical location or events.
  •  
    a great marketing campaign idea. using check-ins to promote upcoming events or event-specific places or even hardcore ambush marketing.

Don Norman's jnd.org / Designing the Infrastructure - 1 views

  • The infrastructure of our computer technology can be overwhelming. My computer's infrastructure gets more complex each year, and all this complexity requires attention. Upgrades and security modifications. The need to change passwords for many accounts, and the need to keep my list of passwords up to date, synchronized across all my computers. The need to reboot, defragment, do continual scans for viruses and malcontent software, the need to renew batteries and accounts. Backup files. It seems that every day I spend considerable time on the infrastructure. Because the ability to maintain infrastructure is seldom designed with care, each simple activity can become daunting. Each new device purchased requires installation, complete with registration, agreeing to unread but undoubtedly onerous legal conditions, and finding space and sockets for all the communication and power cable. Did I mention that these invariably require stopping all work, saving everything, and rebooting, after typing in a long, complex registration number? I should have.
  • Infrastructure is taken for granted. It is time it is given as much attention as the primary applications, else maintaining the infrastructure will itself become our primary activity.
  • It is time to work on infrastructure. It threatens to dominate our lives with ugliness, frustration, and work. We need to spend more time on the designs for infrastructure. We need to make it more attractive, more accessible, and easier to maintain. Infrastructure is intended to be hidden, to provide the foundation for everyday life. If we do not respond, it will dominate our lives, preventing us attending to our priory concerns and interests and instead, just keeping ahead of the maintenance demands.
  •  
    When I think about "infrastructure", I normally think about roads, wires, sewerage and so on. But how about educational technology and instructional design? From reading Don Norman's musings about infrastructure, I realized that if we want our technological implementations to be successfully adopted, very often it's essential to also consider the infrastructure needed to support our tech designs and implementations. Personally, I think infrastructure for education and instructional design need not always be physical things. They could be intangibles such as having to update a database, notify the relevant people in charge, call this person or that to come unlock the computer lab, etc. My mum's been a teacher for 40+ years. She's great. But she really hates the computer. Not because of the learning needed to use Microsoft Word. She's quite fine with it. But it's all the non-Microsoft Word things that she has to do - reboot, turn the computer on, manage the files, etc... - that makes her scream.  "It is time to work on infrastructure. It threatens to dominate our lives with ugliness, frustration, and work. We need to spend more time on the designs for infrastructure. We need to make it more attractive, more accessible, and easier to maintain. Infrastructure is intended to be hidden, to provide the foundation for everyday life. If we do not respond, it will dominate our lives, preventing us attending to our priory concerns and interests and instead, just keeping ahead of the maintenance demands." - Don Norman Food for thought: What are some underlying "infrastructure" (tangible and intangible) that I may encounter in an educational technology project? Are there existing infrastructure that I can take advantage of to minimize time and $? How can we minimize the amount of infrastructure maintenance needed?

Teacher Training on Technology-Enhanced Instruction - A Holistic Approach - 1 views

  •  
    Tan, Hu, Wong, Wettasinghe (2003) on Information Technology and Singapore Education, Instructional Framework, Instructional Strategies (Direct Instruction, SDL, Group Work, Computer-Mediated Communication, Constructivist Learning, Learning through Experience) Computer As an Administrative Tool - Blackboard ! Computer As a Presentation Tool - from PPT to Prezi? Computer As a Tutor - engage the learners in higher order thinking Computer As a Cognitive Tool - mindtools Conclusion: To successfully integrate IT into teaching and learning in schools is a challenging task that hinges on a lot of factors, including effective teacher training. Darling-Hammond (1994) describes the new paradigm of teacher learning as a place in which opportunities are provided for "learning by teaching, learning by doing and learning by collaborating." In our attempt to avoid reducing such training into teaching of discrete IT skills, or merely talking about it through lectures, we presented an approach that modeled various pedagogies, including direct instruction, self-directed learning, group work, computer-mediated communication, and constructivist learning. We also provided a holistic technology-enhanced environment, for the trainees to experience the use of the computer as an administrative tool, as a presentation tool, as a tutor, and as a cognitive tool. These strategies are built upon theories and studies of learning, as well as the use of IT in education. The results of the trainees' evaluation of the module indicated a generally positive reaction to the module and the perception that the instructional objectives have been achieved. These are encouraging indicators of the effectiveness of our instructional strategies, which we will build upon for further improvement in the subsequent delivery of the module.

20 Ways High Schools Are Using Twitter In The Classroom - 0 views

  • BACKCHANNEL DISCUSSION TOOL High school students can sometimes be quite introverted and shy in the classroom, but outspoken online. Additionally, some high school classes move through discussions quickly, and not all students find the opportunity to speak up in class. Both of these issues are addressed as high school classes encourage a Twitter backchannel discussion, in which quiet, shy, and unable-to-get-a-word-in-edgewise students are able to speak up in class without actually speaking up in class, sharing their comments, insights, and even relevant links through Twitter as the discussion goes on. Educators have found that Twitter backchannel discussions provide for more interaction not just in the classroom, but beyond, as students often enjoy further carrying on the conversation even after class time is over.

  • PROFESSIONAL DEVELOPMENT Twitter makes the education world smaller, connecting principals, teachers, and other education professionals across the U.S. and even around the globe. Principal Sheninger at New Milford High School in New Jersey started using Twitter to keep in touch with parents, but found its real value in reaching out to other educators and collaborating with them. He is able to use the tool to find new ideas, new resources, and ideas for professional development

Free Technology for Teachers: wireWax - Create Interactive Videos and Play Videos Withi... - 1 views

  •  
    wireWax is a new service (still in beta) that takes the concept of YouTube annotations and makes it much better. On wireWax you can build interactive tags into your videos. Each tag that you add to your video have another video from YouTube or Vimeo or an image from Facebook, Flickr, or Instagram. A tag can also include an audio track from SoundCloud or a reference article from Qwiki. What makes using wireWax different from using the YouTube annotations tool is that clicking on your tags (what YouTube calls annotations) does not send you outside of the video you're currently watching. This means that you can watch a video within a video or view a picture or listen to a different audio track within the original video. When you click a tag in the original video the video pauses and the tagged item is displayed.
