as AirPano - Amazing 360 Degree Aerial Panoramas By careertechtesting.blogspot.com Published On :: Thu, 13 Feb 2014 14:53:00 +0000 After a few weeks of cold weather, cloudy skies and snow on the ground my mind begins to wander and think of where I would rather be than here. Hawaii sounds good, doesn't it? Unfortunately, my bank account usually says no to those types of dreams so I found AirPano.com which, at least, took my mind off of how cold I am and provided me a poor man's virtual vacation. AirPano.com was actually better than I expected as it provided incredible 360 degree imagery of landmarks and cities from all over the world. Their website features "over 700 panoramas showing over 120 amazing locations of all continents including Antarctic and the North Pole" and panoramas from some 50 other locations are in the works. Source: AirPano.com Much of the AirPano imagery now includes interactive pinmarks that you can click on to learn more about the places that you are visiting (as you can see on the Venice, Italy panorama below). I think AirPano is a great way to learn about other parts of the world, not only from the amazing images, but also from the history and facts about each site that they provide. Last, but not least, it is a great way to get your mind off of the cold winter weather... Visit Venice, Italy on AirPano.com Full Article CareerTechEd Instruction Online Learning

as New Year's Resolution: Secure Your Assessment System By careertechtesting.blogspot.com Published On :: Wed, 06 Jan 2016 18:03:00 +0000 It's unbelievable that 2016 is here and the school year is half over, but that also means we are closer to the busiest time of year for those of us in the assessment industry. I hope everyone has created and follows a secure assessment policy, but if not, John Kleeman, founder of Questionmark, created Ten tips for Securing Your Assessment System, which provides a secure foundation for your assessment system. It seems security breaches most often occur as we get busy and are more prone to creating shortcuts in our work, but a "system" should help minimize these errors. Please read John's post in its entirety and address any weaknesses in your assessment security: What can you do to make your assessment system more secure? How can you avoid a disruptive data breach where people’s personal information is disclosed? Using a vendor who takes security seriously reduces risk, as I wrote in my blog article Eight ways to check if security is more than skin deep. But security involves both vendor and user. This post gives ten good practice tips on how you as a user or administrator of an assessment system can reduce the risk of data breaches. 1. Don’t give yourself or other administrators unnecessary privileges. Follow the principle of least privilege. It may sound counter-intuitive, but most administrative users don’t need access to all capabilities and data within your system. Limiting access reduces the impact of a data breach if an account is compromised or someone makes a mistake. If you are using Questionmark, allocate appropriate roles to limit people to what they need. 2. When someone leaves the project or organization, remove their access. Don’t allow someone who has left your team to still have access to your assessment data. 3. Follow good password security. Do not share passwords between people. Do not use the same password for two accounts. Choose strong passwords and change them periodically. If someone asks you for your password, never, ever give it. And if a web page doesn’t look right, don’t type your password into it. 4. Install all the patches and secure the system. A common cause of security breaches is failing to install the latest versions of software, and attackers exploit known vulnerabilities. You need to be proactive and always install the latest version of system and application software, set up good technical security and follow the vendor’s recommendations. If you haven’t got the time or resources to do this properly, move to a cloud solution. In a cloud SaaS solution like Questionmark OnDemand, the vendor is responsible for updating Windows, updating the application, monitoring security and ensuring that everything is up to date. 5. Install good quality antivirus / anti-malware software. Reportedly there are nearly a million new or variant malware and viruses produced each day. Protect your computer and those of your co-workers with up to date, professional software to address this threat. 6. Protect any downloaded data. Questions, assessments and reports on results are generally safer on a server or in an on-demand service than on a workstation. If you need to download data locally, set up security procedures to protect it and try to ensure that any download is temporary only. 7. Dispose of data properly. Deleting a file on a computer doesn’t erase the data, it simply erases the index to it. If you use a reputable service like Questionmark OnDemand, if a disk is repaired or reaches end of life, it will be securely destroyed for example by degaussing. But if you download data locally or use installable software to manage your assessments, you need to do this yourselves. A recent study suggested that about half of used hard drives sold online contain residual data. Make sure this is not your assessment data! 8. Be careful about clicking on a link or attachment in an email. Phishing attacks use email or malicious websites (clicking on a link) to collect sensitive information or infect your machine with malware and viruses. Such attacks could even be aimed at your organization or assessment activity directly (this is called spear phishing!). Think before clicking. 9. Be aware of social engineering. Social engineering is when someone tries to trick you or someone else into a security breach. For example someone might ring up and claim to be a student who wants their results, but really is an imposter. Or someone might spoof an email from your boss asking for the questions for the next test to review. Be wary of strange phone calls or emails that ask for something urgent. If something seems suspicious, clear it with a security professional before you give them info or ask a caller to hang up and call them back on an official number. 10. Conduct security awareness training. If you’re not already doing this, organize training sessions for all your authors, proctors, administrators and other users to help them be security aware. if you can, deliver tests after the training to check understanding. Sharing this blog article with your co-workers would be a great way to start. To see more Questionmark posts click HERE.

as The Educator's Guide to Hashtags By careertechtesting.blogspot.com Published On :: Wed, 13 Jan 2016 18:26:00 +0000 Follow us on Twitter! @CareerTechTest Whether you're a social media novice or not, hashtags may seem confusing and inessential. These short links (hashtags) preceded by the pound sign (#) are integral to the way we communicate online and it's important to know how to use them. Can hashtags be fun? Absolutely! On Twitter, the pound sign (or hash) turns any word or group of words into a searchable link. This allows you to organize content and track discussion topics based on those keywords. So, if you want to post about the NFL Super Bowl, you would include #SuperBowl in your tweet to join the conversation (or simply search for the hashtag to follow the discussion). Clicking on a hashtag will allow you to see all the posts that mention the subject in real time. I also recommend using a social media management platform, such as HooteSuite, TweetDeck, etc., where you can create columns with hashtag topics. I like the ability to monitor several discussions, i.e. #edchat, #lrnchat, #careerteched, at once and all on the same screen. I've created a list of popular educational hashtags and tried to categorize them for you (see below). It definitely isn't all inclusive, but it's a good starting point and I hope you will share any new educational hashtags you find interesting and helpful! (Also, hashtags are now a staple to social media and their use has been extended to other social media platforms.) Popular Educational Hashtags Hashtag Category Career and Technology Education #careerteched #CTE #vision15 College #highered Curriculum #cchat Distance Education #disted #elearning #k12online #mlearning #onlinelearning Groups and Chats #edchat Educational Technology #educhat Education Chat #lrnchat Social Media and Education #oklaed Oklahoma Education Chat Instruction/Learning #blendchat Blended Learning #blendedlearning Blended Learning #education #elearning Electronic Learning #flipclass Blended Learning #GBL Game-Based Learning #ntchat New Teachers #onlinelearning Blended Learning #pbl/#pblchat Project-Based Learning #studentcentered Blended Learning #teachered #teachers Language #bilingual #efl English as a Foreign Language #ell English Language Learning #esl English as a Second Languae #tesol Teaching English to Speakers of Other Languages Leadership #edleadership #eduleaders Resources #education #educational videos #educationresources #learning #lessonplans #library #research #teachers #TLChat Twitter Librarians #TT Teacher Tuesday where educators suggest others to follow Special Needs #gifted Gifted Education #GTChat Gifted Education #spedchat Special Education Science #STEM Technology #1:1 #apps #blendchat Blended Learning #BYOD Bring Your Own Device #EdApps Educational Apps #edtech Educational Technology #edtechchat Educational Technology #elearning Electronic Learning #ipadchat iPad #iNACOL International Association of Online Learning #iste International Society for Technology in Education #mlearning Mobile Learning #mobile Mobile Learning #slide2learn iDevices and Learning #vitalcpd Effective Use of Technology in the Classroom #web20 Full Article CareerTechEd Education Mobile Learning Online Learning Research Technology Training and Resources Twitter Web 2.0
as Sleep - A Student's Most Important Homework Assignment By careertechtesting.blogspot.com Published On :: Mon, 22 Aug 2016 16:11:00 +0000 Want to know how sleep "resets" your brain? How memories are formed and retained? Then watch The Benefits of a Good Night's Sleep, embedded below, and learn how sleep balances and regulates the body's vital systems which, in turn, affects declarative and procedural memory. This short TED-Ed lesson by Shai Marcu is an important topic as school starts and students will soon be staying up late or all night in order to cram for tests and other educational requirements. Marcu goes into detail describing the neurological importance of 8 hours of sleep, but the application is interesting as going to sleep three hours after memorizing math formulas (declarative memory) and one hour after practicing music scales (procedural memory) is the most ideal. I'm left wondering what I might have accomplished if my sleep and learning patterns were consistent during my formative years...
