SA targets 14 000 new teachers by 2014

first_img27 February 2013 The South African government is pushing to produce more than 14 000 new teachers by 2014, Higher Education and Training Minister Blade Nzimande said at the launch of a New Teachers Education Programme at Siyabuswa in Mpumalanga province on Tuesday. Nzimande launched the programme at the reopening of the Siyabuswa Campus, formerly the KwaNdebele College of Education. Siyabuswa Campus will form part of the province’s new university, which is due to be completed next year. According to Nzimande, research indicates that South Africa should aim to produce about 18 000 new teachers annually to meet its needs in the short to medium term. “In terms of planning our projections, we will be producing in excess of 14 000 new teachers by 2014.” Nzimande said his department was implementing a three-step approach to strengthening and expanding the country’s teacher education capacity. These included making sure that the current education capacity of universities was fully utilised, expanding teacher education capacity on existing university campuses through the allocation of funds to develop new infrastructure, and establishing new campuses for teacher education. He said work was in progress to establish three additional teacher education campuses, in KwaZulu-Natal, the Eastern Cape and Limpopo province, while the country’s two new universities – to be built in Mpumalanga and the Northern Cape – would both include a “full teacher education footprint”. This, along with “the new and growing involvement of the Vaal University of Technology in initial teacher education, will bring us very close to producing the required 18 000 new teachers per year in the medium term,” Nzimande said.

Insulating Window Shades

first_imgThey’re not cheap, but they workSo how do they work? Well, they definitely insulate — when opened in the morning a little puff of cold air drops out. And there is condensation on the glass, notably more than the unsealed, single row cellular shades we have elsewhere in the house.My colleague and friend Andy Shapiro did some careful measuring on one of his and calculates that the effective added R-value is about R-4.These shades aren’t cheap, although they are a lot less money than a window replacement. If you have leaky windows, these won’t solve that problem — they’re not that airtight. A storm window will do a better job of sealing, but won’t add as much insulating value.I think that if you are considering shades at all for privacy reasons, and have reasonably tight windows, an insulating shade such as these can make sense, and they handle fairly large windows well. We’ve noticed that the largest one, covering a triple window about 7 feet wide and 5 feet tall, is perhaps a bit too large for the hardware that rolls it up — we help it up with one hand as we retract it in the morning.Putting the two shades in the living room down definitely makes that room more comfortable to be in, as the two largest windows in the house are on the east and south of that space, and it’s where we spend a lot of time. The change in the radiant temperature is noticeable. So all in all we consider this to be a success as we’ve applied it here.

BLOGS BY MARC ROSENBAUM Self-Cleaning OvensA Tough Energy Code Is the Worker’s FriendInstalling a Photovoltaic SystemLiving With Point-Source HeatInstalling a Ductless Minisplit SystemSeasonal Changes in Electrical Loads One of the technologies I have tried in my house is an insulating window shade with side tracks. I got four Ecosmart cellular shades from Gordon Clements at Gordon’s Window Decor. One is translucent, and the other three are blackout shades, achieving that by using aluminum foil inside the cells. Because the foil is reflective to radiant heat transfer, these shades have a higher insulating value than the translucent version. They also have two rows of cells, to further increase insulating value (see Image #1 on the right).The side edges of the shades are slit; a plastic fin that is installed on the sides of the window opening runs in the slit and makes a rudimentary and simple seal. The bottom has a weatherstrip to seal to the window sill. Image #2 (below) is a close-up of the shade and side fin.Image #3 (below) shows what the shade looks like when it is pulled fully down. Image #4 shows the shade with the top partially down — nice for daylight with some privacy.

Google Glass vs. Apple iWatch: How Do They Compare?

first_imgWhy IoT Apps are Eating Device Interfaces The Rise and Rise of Mobile Payment Technology greg roberts Tags:#Apple#Google#Google Glass#iWatch What it Takes to Build a Highly Secure FinTech …center_img Related Posts Guest author Greg Roberts is co-founder and chief designer of the upcoming battle of wearable computing, it’s Google Glass vs. iWatch. Google vs. Apple. Clash of the Titans.(See also Google Glass: What Do You Want To Know About Google’s Internet Eyewear?)These two companies attack the challenge of wearable computing from two completely different perspectives. Which one will dominate?Sure, the battle is a little lopsided in that Google Glass is a real product, albeit still for developers only, while iWatch remains only speculation. But let’s assume that both will be real products soon enough and look at their individual strengths and weaknesses.Face vs. WristIt all starts with physical location, or what real-estate the devices occupy on the user’s body:iWatch: The wrist is an easy target, as it has been the home of technological advancements from the beginning of the wristwatch era, c. 1920 and peaking during the digital watch revolution in the 1970s. Many people are used to wearing technology on their wrists.It is easy to imagine that by the time we see the iWatch 3gs, it specs will surpass even the best of today’s smartphones. But in all its glory, the iWatch is really just moving the tech from your pocket to your wrist, with a smaller display. Or, in a less ambitious scenario, the smartwatch is merely a satellite hub to your existing smartphone, showing filtered notifications as needed, with a limited touch surface with which to interact.Plus, you will still have to pull up your sleeve to see the display. (On the other hand, it’s not obtrusive when not in use.)Google Glass: Putting technology on your face is a much bigger cultural hurdle. For Glass to succeed, humans will need to get used to wearing a computer on their face – and to looking at and interacting with other people who have computers on their face.Google Glass, however, doesn’t just shift the location of the phone screen: instead it offers a completely new computing paradigm.The unique benefits of smartglass includeTrue hands-free computingLow-profile camera that records true first person PoV video/stillsHead tracking (it knows where you are looking)Private audio (via bone conduction)Private viewing of informationNone of these benefits can be realized with even the most most sophisticated smartwatch. In short, Google Glass affords a far more intimate connection to the infosphere than any other wearable tech, short of implants.(See also Why Google Glass Is Far More Important Than Any Smartwatch.)Importantly, Glass superimposes net information atop your natural view of the world. Users of smartphones and smartwatches find themselves sucked into screens, walling off the outside world. The Google Glass interface instead places a small, semi-transparent overlay seamlessly atop actual waking reality.That means Google Glass could dramatically reduce the time and effort required to retrieve information from your files or the Internet. While Google Glass is still a prototyple, a well-engineered smartglass could reduce many such tasks from more 12 seconds to less than 3 seconds.Big Time SavingsWhile saving 8 seconds may not seem like a lot, multiply it times the 100 or more times a day users typically accesses their smartphones, and it becomes massive. In fact, that aspect alone could potentially save users 13 minutes a day, or almost 80 hours a year. That’s two full weeks of work!It would also reduce muscular exertion for these processes: Compare getting a phone out of your pocket, pushing several buttons and then typing to simply tilting your head skyward and saying “OK Glass.“Results? Information is no longer at your fingertips, it’s closer than your fingertips. Information retrieval could become so fluid that it becomes ingrained into your very consciousness… ideally becoming a genuinely natural extension of our biological brains and thought processes.Google Glass Has A Long Way To GoAs it stands, Google Glass is a long way from delivering on that promise, but the potential benefits of a device that fully realizes the concepts Glass pioneers are truly revolutionary.Will those potential benefits outweigh the in-your-face social and fashion issue that might make people hesistant to wear Google Glass, especially in public?Maybe, especially if Google can successfully position the product as a coveted fashion item that transcends tech. If that happens, the iWatch will be nothing but an afterthought. Role of Mobile App Analytics In-App Engagementlast_img read more
